1. The Two Clocks: Registration in 20 Days, Tax in 365

A new resident lives under two clocks that start on different days and measure different things. Mixing them up is the single most common mover error on the internet — and the reason our companion guide on the 10-day vs 20-day rule exists. This page states both clocks, side by side, in one table, and then never confuses them again.

	Clock 1 — the 20-day registration clock	Clock 2 — the 365-day tax clock
What it is	You must register a vehicle previously registered in another state or country within 20 days of becoming a California resident or bringing the vehicle into the state.	The DMV requires use tax or a CDTFA-111 for a vehicle purchased outside California on or after October 1, 2008, and brought into California within 365 days of the purchase date.
Source	DMV New California Resident Portal: “you must register it within 20 days of becoming a resident or bringing it into the state.”	DMV Vehicle Industry Registration Procedures Manual §4.040, “Vehicle/Vessel Purchased Out of State (CR&TC §6248)”.
Starts	The day you become a resident — intent to live in California six months or more in one year — or the day you bring the car in, whichever the facts support. Employment in California starts the residency clock on day one; there is no settling-in grace period.	The date of purchase — the day you bought the car, not the day you moved, not the day it entered California.
Ends	Day 20 after the trigger.	Day 365 after the purchase date. (The statute says “within 12 months”; the DMV manual operationalises it as 365 days — see section 2.)
What happens at the end	Late registration penalties under Vehicle Code §9554.5. The tiers are our 10-day vs 20-day guide’s subject — this page does not reprint them.	The §6248 presumption stops arising on its own terms for entries after the window. That does not mean “no tax ever” — other provisions and facts still apply.
Who collects	DMV (registration).	DMV collects the use tax at registration, on CDTFA’s behalf.

Why the two clocks collide for movers: registration is when the tax is collected. A mover who bought a car eight months ago and moved yesterday faces both clocks at once — 20 days to register, and a live 365-day presumption. A mover who bought a car 14 months ago and moved yesterday faces only the 20-day clock for the tax presumption’s purposes — but still has to register in 20 days, and still has to be ready to show the purchase date, because the DMV counter is where the 365-day question gets asked. The worked examples in section 3 are built on this collision.

Residency — the trigger for both clocks. The DMV portal states the residency test plainly: you are a California resident if you intend to live in the state for six months or more in one year. Its intent examples: present in California six months or longer within a 12-month period (and not visiting on a temporary or transient basis); registered to vote in California; employed in California; place of business in California; paying resident tuition at a public institution; dependents attending a California primary or secondary school; homeowner with a property-tax exemption; renting a property as a primary residence; claiming California residency to obtain a privilege or benefit nonresidents cannot obtain; holding a current California driver’s licence or ID; or being determined a resident because acts or events show presence more than temporary or transient. The list expressly excludes military personnel. Vehicle Code §516 is the statutory hook CDTFA cites for the same test, and presence in California for six months or more in any 12-month period creates a presumption of residency. Licence questions belong to the 10-day vs 20-day guide; this page stays on the tax.

2. The 12-Month Rule, Precisely, for Movers

California does not charge “sales tax” on a car you bought in another state. It charges use tax — the mirror-image tax on storing, using, or consuming in California something you bought from a retailer without paying California sales tax. If you bought a vehicle outside California, first functionally used it outside California, and then brought it into California within 12 months of purchase, California presumes you bought it for use in California and taxes it — unless you rebut that presumption with documentary evidence that you bought it for use outside California during those first 12 months (Revenue & Taxation Code §6248). The full rule — every trigger, every carve-out, the complete evidence checklist, and the full credit arithmetic — lives on our companion page, Out-of-State Car Use Tax: The 12-Month Rule. This page gives you the rule as a mover needs it: the triggers, the two wordings, and the proof.

The presumption, in the statute’s own words (paraphrased closely)

RTC §6248(a) creates a rebuttable presumption that any vehicle, vessel, or aircraft bought outside California and brought into California within 12 months from the date of purchase was acquired for storage, use, or other consumption in California and is subject to use tax — if any one of four conditions occurs:

#	Condition	What it means for a mover
1	The vehicle was purchased by a California resident (Vehicle Code §516).	The strongest trigger for movers. If you were already a California resident when you bought — a California job, a California home, a California licence — the presumption bites on this condition alone.
2	The vehicle was subject to California registration during the first 12 months of ownership.	The trigger most movers actually trip: first registration is the act of registering. If you register in California within the first 12 months of owning the car, this condition is met.
3	For a vessel or aircraft, it was subject to California property tax during the first 12 months.	Not a car rule. Listed here so you know it exists — and that it does not apply to your car.
4	If purchased by a nonresident, it was used or stored in California more than one-half of the time during the first 12 months of ownership.	The test for the genuine nonresident who later moved. A mover who kept the car out of state for most of the first 12 months is much harder to catch on this condition — but condition 2 still applies once you register.

CDTFA’s 12-month-test FAQ states the same test with one extra, crucial qualifier: the vehicle must have been first functionally used outside California and thereafter brought in within 12 months. And Publication 52 (November 2025, p. 6) adds the operational rule the page must print in bold: “The four conditions listed above are independent conditions… Only one of the conditions needs to be met for the presumption to apply.” A mover who is a California resident does not also need to have registered the car in California for the presumption to bite; resident-purchase alone is enough.

The two wordings — “12 months” vs “365 days”. The statute and CDTFA say “within 12 months”; the DMV manual (§4.040) says “brought into California within 365 days from the purchase date.” For ordinary cases they coincide. This page uses “within 12 months of purchase” as its headline wording and footnotes the DMV manual’s “365 days” phrasing. It does not invent a tie-breaker for leap years or month-length edge cases, and it does not present a boundary-day entry (day 364/365/366) as a settled answer: entries in the final week of the window are presented as “treat as inside the window; do not plan a move on the boundary” (see Example D in section 3).

Era windows. The CDTFA FAQ states the 12-month-test provisions apply to purchases from 2 October 2004 through 30 June 2007, and on or after 1 October 2008. The DMV manual operationalises the same rule as purchases on or after 1 October 2008 brought in within 365 days. Purchases in the gap windows (before October 2, 2004, and July 1, 2007 through September 30, 2008) fall under Regulation 1620 and the old 90-day test — see section 9 for why that matters to today’s movers (it is the origin of the 90-day ghost).

What “first functionally used” means — and why it kills the “I never drove it” argument

CDTFA’s vehicles guide defines functional use as use for the purposes for which the vehicle was designed: a personal-use vehicle is functionally used when merely driven; a bus or truck designed for a commercial or special purpose is not functionally used until used for that purpose. Publication 52 states the negative side plainly: if you purchase a vehicle outside California but first functionally use it IN California, the exclusion does not apply and the purchase and use is subject to use tax — the whole 12-month rebuttal framework presupposes genuine first use outside the state. For movers this has a sharp edge: a car bought out of state, trailered to California, and first driven in California was arguably first functionally used in California. This page does not promise that trailering alone defeats the presumption — it says the paper trail (delivery statement, out-of-state registration, insurance start date) is what CDTFA evaluates.

Who counts as a “California resident” for this test

Vehicle Code §516, as summarised by CDTFA’s FAQ and Publication 52: a “resident” is any person (including a firm, partnership, association, LLC, or corporation) who shows an intent to live or be located in California on more than a temporary basis. Presence in California for six months or more in any 12-month period creates a presumption of residency. Factors CDTFA lists as evidence of residency include: where you are registered to vote; the location of your place of employment or business; filing a homeowner’s property-tax exemption; possession of a California driver’s licence; renting or leasing a home for use as a residence; and a declaration of residency to obtain a privilege or benefit not ordinarily extended to nonresidents.

The mover’s wrinkle: you can be a California resident for §6248 purposes before you physically move — for example, if you accepted a California job and rented a California home while the car was still in your old state. Condition 1 can therefore bite even on a car bought while you still lived elsewhere, if the residency facts already pointed at California. Conversely, a genuine nonresident who bought the car, used it out of state, and only later decided to move is tested under condition 4 (used or stored in California more than one-half of the time during the first 12 months) — a much harder trigger for CDTFA to meet on a mover who kept the car out of state. The page states this asymmetry plainly: the presumption is at its strongest for the person who was already a California resident when they bought, and weakest for the genuine nonresident who later moved — but in both cases, bringing the car in within 12 months plus California registration in the first 12 months (condition 2) is the trigger most movers will actually trip, because first registration is the act of registering.

“Rebuttable” — what it actually takes to win, for a mover

§6248(b): “This presumption may be controverted by documentary evidence that the vehicle… was purchased for use outside of this state during the first 12 months of ownership. This evidence may include, but is not limited to, evidence of registration… with the proper authority, outside of this state.” That statutory sentence is deliberately open-ended (“may include, but is not limited to”). CDTFA fills it in with the seven-document list in section 5. The burden is on the purchaser, the evidence is documentary (not “I intended…”), and CDTFA — not DMV — evaluates it: CDTFA’s FAQ says the documentation “must be submitted to the California Department of Tax and Fee Administration (CDTFA) for evaluation.”

One subtle, reader-friendly point from Publication 52 that most competitor pages miss: a voluntary move to California within 12 months of purchase does not automatically prevent you from overcoming the presumption. Publication 52 says evidence that at purchase time the buyer had no intention the vehicle would be used in California is, alone, sufficient — and that a voluntary move is “one factor to consider, along with all the other facts and circumstances.” So the message to recent movers is not “you’re stuck” — it is “your move is one factor, and your out-of-state paper trail is what decides it.” The companion trap to name: registering the vehicle with California DMV itself evidences intent to use it in California (CDTFA FAQ) — so a California resident who registers in California while claiming “not for use in California” is fighting their own paperwork, and CDTFA’s route for that person is the CDTFA-111 clearance path (section 6.3), with proof at the end of the 12 months that the vehicle did not enter California during that period.

The two narrow carve-outs inside the 12-month window (cars only)

(a) Warranty or repair service — vehicles (30 days). §6248(f) and CDTFA’s vehicles guide: a vehicle brought into California during the first 12 months for the exclusive purpose of warranty or repair service is not presumed purchased for use in California if it is used or stored in California for that purpose for 30 days or less. The 30-day period begins when the vehicle enters California, includes travel to and from the facility, and ends when the vehicle is returned to a point outside the state. Required documentary evidence: a work order stating the dates the vehicle was in the facility’s possession, plus the owner’s statement specifying dates of travel to and from the facility. One day over 30, or any non-repair use in California during the stay, and the carve-out fails on its own terms.

(b) Repair, retrofit, or modification — vessels and aircraft only (not vehicles). §6248(e): an aircraft or vessel brought in exclusively for repair, retrofit, or modification is not deemed acquired for California use, provided the work is by a qualifying facility. CDTFA’s FAQ confirms: “This exclusion does not apply to vehicles.” One clarifying sentence only — to stop readers importing a boat/plane rule into a car purchase.

(c) Interstate or foreign commerce — the separate track. §6248(c) removes interstate/foreign-commerce vehicles from §6248, and Regulation 1620 supplies the tests: no use tax if the vehicle was first functionally used outside California AND one-half or more of the miles travelled during the six-month period immediately following entry into California are commercial miles in interstate or foreign commerce (commercial = business use; personal use excluded). There is also the continuous-use exemption: property first used in interstate/foreign commerce before entering California and thereafter continuously so used both within and without California, and not exclusively in California. For a mover’s page this is a “if you are a genuine interstate commercial operator, talk to CDTFA” sidebar — not a loophole for personal cars. Personal-use miles do not count as commercial miles, and this page says so.

§6247 vs §6248 — the distinction in one box

	§6247	§6248
Whose presumption?	The retailer’s — property delivered outside California to a purchaser the retailer knows is a California resident is presumed purchased for California use.	The buyer’s — a vehicle bought outside California and brought in within 12 months is presumed purchased for California use if a §6248 condition is met.
Rebutted how?	Retailer’s timely, good-faith acceptance of the buyer’s signed written statement (CDTFA-447) that it was purchased for use at a designated point outside California; plus other satisfactory evidence.	Buyer’s documentary evidence of purchase for use outside California during the first 12 months (§6248(b); checklist in section 5).
Forms	CDTFA-447 (purchaser statement) + CDTFA-448 (dealer’s statement of delivery outside California).	CDTFA-106 → CDTFA-111 clearance (section 6.3); CDTFA-447/448 are evidence of the out-of-state story, not a §6248 clearance by themselves.
Failure mode to name	A dealer who accepts a 447/448 from a California resident and then registers the vehicle in California for the buyer has its good-faith acceptance questioned and may be liable for failure to collect (CDTFA FAQ). A 447 does not relieve the buyer: CDTFA-447’s own notice says if the vehicle is brought into California within the first 12 months (other than qualifying warranty/repair), it is presumed purchased for California use and the buyer may owe use tax directly to CDTFA.	Registering with California DMV evidences intent to use in California (CDTFA FAQ) — the buyer’s own registration undercuts a “not for California use” claim.

The one-line takeaway: §6247 protects the seller who collected a proper statement; §6248 taxes the buyer who brings the car in within 12 months. A signed 447 in the glovebox does not, by itself, beat §6248. The full treatment — including the dealer’s liability and the annotation law — is on the general use-tax page.

3. Worked Date Examples — the Mover’s Calendar

Every example states three dates — purchase date, move/entry date, days between — and the consequence. The day counts were recomputed on October 31, 2026; the method is simple enough to check yourself: entry date minus purchase date. All purchase prices and rates in these examples are illustrative and labelled; the only rate used is the verified 7.25% statewide base, before district taxes.

Example	Purchase date	Entry into California	Days	Result
A — Inside the window, no contest	January 15, 2026 (Texas)	September 1, 2026	229	Presumption applies. Pay with the §6406 credit, build the section 5 rebuttal, or take the CDTFA-111 route.
B — Outside the window	March 1, 2025	April 15, 2026	410	Presumption does not arise on its own terms. Keep the old registration as evidence of the timeline. “Presumption off” — not “tax-free”.
C — Inside by three weeks	December 10, 2025	November 20, 2026	345	Presumption applies. A car bought “about a year ago” is very often still inside the window.
D — The boundary	November 1, 2025	October 31, 2026	364	Inside by one day. Entry on November 1, 2026 would be 365 days; November 2 would be 366. Treat final-week entries as inside the window.
E — Bought just before the move	June 10, 2026	June 30, 2026	20	Deep inside the window; the presumption applies on every trigger. Expect to pay; bring the purchase agreement and claim the credit.

Example A — Inside the window, no contest. Bought January 15, 2026 in Texas; first used it there; moved to California and brought the car in September 1, 2026. Days between purchase and entry: January 16–31 = 16, February = 28, March = 31, April = 30, May = 31, June = 30, July = 31, August = 31, September 1 = 1 → 229 days. Inside 365. The §6248 presumption applies (brought in within 12 months + California registration in the first 12 months will follow). The mover’s realistic paths: pay with the §6406 credit, or build the section 5 rebuttal, or the CDTFA-111 route (section 6.3). The voluntary move alone does not defeat the rebuttal — but the paper trail decides it.

Example B — Outside the window, presumption off. Bought March 1, 2025; registered and insured it in the old state; moved to California April 15, 2026. March 1, 2025 → March 1, 2026 = 365 days (2025 is not a leap year); March 1 → April 15, 2026 = 31 + 14 = 45 days → 410 days. Outside 365. The §6248 presumption does not arise on its own terms. Keep the old registration as evidence of the timeline. This page presents this as “presumption off,” not “tax-free” — other use-tax provisions and the actual facts still apply, and a flat “13th month = exempt” sentence is banned from this guide (see section 9).

Example C — Inside by three weeks. Bought December 10, 2025; moved November 20, 2026. December 10 → December 31 = 21 days; 2026: January 31, February 28, March 31, April 30, May 31, June 30, July 31, August 31, September 30, October 31, November 20 = 21 + 31 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 20 = 345 days. Inside 365, with 20 days to spare. The lesson: a car bought “about a year ago” is very often still inside the window — movers who guess “it was a year ago, so I’m clear” are the ones who get surprised at the counter. Count the days; do not estimate the year.

Example D — The boundary (presented as a warning, not a verdict). Bought November 1, 2025; car enters California October 31, 2026. November 1 → December 1 = 30; December 1 → January 1 = 31; January 1 → February 1 = 31; February 1 → March 1 = 28; March 1 → April 1 = 31; April 1 → May 1 = 30; May 1 → June 1 = 31; June 1 → July 1 = 30; July 1 → August 1 = 31; August 1 → September 1 = 31; September 1 → October 1 = 30; October 1 → October 31 = 30 → 364 days. Inside by one day. Entry on November 1, 2026 would be 365 days; entry on November 2, 2026 would be 366. The statute says “within 12 months” and the DMV manual says “within 365 days,” and no source found in this research resolves the exact boundary day. This guide therefore does not declare day 365 “in” or “out.” It says: entries in the final week of the window are boundary cases — treat them as inside the window, bring the full section 5 paper trail, and do not plan a move date on the boundary. A mover who schedules a move to land on day 366 to “beat the clock” is gambling on a one-day reading of a rule that has two wordings.

Example E — Bought just before the move. Bought June 10, 2026; moved June 30, 2026 — 20 days between purchase and entry. Deep inside the window; the presumption applies on every trigger (resident purchase if the buyer was already a California resident; California registration in the first 12 months in any event). This is the case where the rebuttal is hardest and the credit matters most: the buyer should expect to pay, bring the purchase agreement showing the other-state tax, and claim the §6406 credit at the counter. It is also the case where the “buy before you move” decision (our buy-before-moving guide’s subject) has already been made — this page does not re-litigate it.

Example F — “Register now, prove later” (the CDTFA-111 resident route). A California resident buys a car out of state, first uses it out of state, and registers it with California DMV — but the car does not enter California during the first 12 months of ownership. CDTFA’s FAQ provides the route: the resident may request a CDTFA-111 clearance certificate so registration completes without paying use tax at that time; at the end of the first 12 months the resident must clearly demonstrate through documentary evidence that the vehicle did not enter the state during that period. Without that evidence, it is presumed the vehicle was purchased for use in California and tax would be owed. Print both halves: the clearance is not an exemption, it is a deferral with a proof deadline at month 12.

Example G — The storage trap (“wait out the clock” fails). Bought out of state in January; the buyer moves to California in March but leaves the car in a garage in the old state, planning to bring it in after the 12 months expire. Two problems, both verified in DMV manual §4.040: (1) the 365-day counter runs from the purchase date, not from the move date — storing the car does not pause or reset it, and the entry date is what gets compared to the purchase date; (2) referral to CDTFA is required if the vehicle was purchased out of state and stored for a period of time before entering California. So the storage strategy does not avoid the tax question — it guarantees a CDTFA referral. Do not store the car to run out the clock; the manual names storage as a referral trigger.

Example H — The warranty trip. Bought out of state, first functionally used there; at month 6 the car enters California solely for warranty work, stays 18 days including travel to and from the shop, and returns out of state with a work order showing the shop’s possession dates plus the owner’s travel-date statement. On §6248(f)’s terms the car is not presumed purchased for California use for that entry. If the same trip lasted 40 days, or mixed in a California road trip, the carve-out fails — the 30-day limit includes travel time and the purpose must be exclusive.

4. How Much You Owe: the Credit, in Dollars

RTC §6406: “A credit shall be allowed against, but shall not exceed, the taxes imposed… to the extent that the person has paid a retail sales or use tax, or reimbursement therefor, imposed with respect to that property by any other state, political subdivision thereof, or the District of Columbia prior to the storage, use, or other consumption of that property in this state.” Three limiters hide in that sentence, and this page states all three in plain English:

• Same property, same kind of tax. The credit is for a retail sales or use tax (or reimbursement) imposed on that property by another state (or its subdivision, or D.C.). It is not a general credit for “taxes I paid somewhere.” A dealer “handling fee,” title fee, registration fee, or documentation charge from the other state is not a retail sales/use tax and does not create credit — the credit is measured by the tax line on the purchase documents.
• Paid BEFORE California use. The other state’s tax must have been paid prior to the storage, use, or consumption in California that triggers California’s tax. Tax paid to another state after you already started using the car in California does not retroactively create a §6406 credit on these words.
• Capped — “shall not exceed.” The credit can never be larger than the California taxes it offsets, and it is apportioned across those taxes in proportion to their amounts (state + district components). No refund of an excess, no carry-forward is stated in §6406 — and this page does not invent one.

The rate: the use-tax rate is the same as the sales-tax rate, determined by the address where the vehicle is registered (CDTFA vehicles guide). The statewide base rate is 7.25%, and in most areas local district taxes sit on top of it. This page never prints a single “California use tax rate” as if it were one number, and never prints a county or city rate from memory — it sends the reader to CDTFA’s city/county rate tables and address lookup to find their own combined rate. Any worked example that uses a combined rate above 7.25% is labelled ILLUSTRATIVE, with the rate stated as an assumption — never as “the Los Angeles rate” or “the San Francisco rate”.

CDTFA’s own credit examples (verified, use first — the only credit numbers this page needs): you paid $1,500 in sales/use tax to another state; California use tax due is $2,000. Balance due to California: $2,000 − $1,500 = $500. Publication 52’s smaller twin: paid $150, California due $200 → balance $50; paid $200, California due $150 → California use tax $0. (CDTFA vehicles guide + Pub 52 p. 9.)

One illustration with the verified base rate (labelled, not a rate claim): purchase price $30,000; no tax paid to another state (credit $0); combined rate assumed = 7.25% base only, i.e. the calculation before any district taxes the reader’s address may add. $30,000 × 7.25% = $2,175 California use tax before district taxes. In most California addresses district taxes raise the combined rate above 7.25% — look yours up on CDTFA’s rate tables; every extra 1% on $30,000 is another $300. The full worked credit arithmetic — six examples, dollars-not-rates math, the lease-payment proviso and the lessor trap — lives on the general use-tax page; this page links, it does not duplicate.

Claiming the credit at DMV: provide DMV with a copy of the purchase agreement showing the amount of sales/use tax paid to the other state; DMV can handle the credit directly (Publication 52, pp. 6 and 9). One caution, carried honestly: several secondary sources citing DMV manual §4.015 state the credit is claimed by submitting a Statement of Facts (REG 256) certifying the tax paid to the other state. That section was not opened in this research, so this page prints only the verified Publication 52 version and does not present REG 256 as the credit-claim form.

The tax base (one paragraph, CDTFA’s own examples): the tax is based on the total purchase price, including cash, checks, the payment or assumption of a loan or debt, and the fair market value of any property and/or services traded, bartered, or exchanged. CDTFA’s vehicles guide examples: taking over a friend’s loan payments = tax on the loan balance assumed plus any cash paid, even with no cash to the friend; trading a $3,000 car plus $2,000 cash for a $5,000 car = tax on the full $5,000, not the $2,000 cash difference; a straight swap = tax on the $5,000 market value of the car traded; painting services worth $5,000 for a car = tax on $5,000. The warning to carry away: “the cash that changed hands” is not the tax base.

5. The Rebuttal Checklist — Gather This Before Your DMV Appointment

This is CDTFA’s own document set, reframed for a mover walking into first registration. The full exposition — tier by tier, with the eight-year retention rule and the “what does not rebut” list — lives on the general use-tax page. This page carries the checklist in the order the counter asks for it, with the mover-specific handling rules.

Bring these, in this order:

CDTFA also weighs (frame as “CDTFA also weighs…”, not as documents): whether you had a residence out of state at purchase time; where the vehicle was insured; how much time the vehicle spent in California during the first 12 months; whether your move to California was voluntary or involuntary — with the section 2 rule that a voluntary move alone does not defeat the rebuttal.

Handling rules — print these with the checklist:

• Retention: at least eight years. Publication 52 (p. 7): “All documentary evidence must be retained for at least eight years.” Keep everything for at least eight years — the purchase file, the credit proof, the clearance if any, and the registration paperwork. It is the single most actionable line in this section.
• Submit to CDTFA for evaluation (FAQ), not just “show DMV.” At DMV, the practical fork is: pay the tax (or get the credit applied) and register, or seek a CDTFA-111 clearance first (section 6.3) — and DMV withholds registration/transfer if the applicant neither pays nor produces a CDTFA-111 (§4.040).
• Dates matter more than stories — the REG 256 rule. The DMV manual (§4.040) requires strict adherence to the “date of purchase” definition: the applicant must write the date of entry into California, date of delivery, and all similar data on the application, and a completed, signed REG 256 (Statement of Facts) is required for any alteration to the date of entry or date of purchase. Referral to CDTFA is required if the vehicle was stored for a period before entering California, or if the applicant maintains the application date differs from the date of actual physical possession. Page translation: do not “fix” a date on the form — a corrected date without a REG 256 is exactly how a clean rebuttal becomes a credibility problem. Write the dates right the first time; if a date on your paperwork is wrong, say so, file the REG 256, and expect the referral.
• What does NOT rebut, on its own: a bare statement of intent with no documents; a Montana/elsewhere LLC registration with no genuine out-of-state use paper trail (see the shell-company rule in section 2 and the SB 1406 box in section 8); a CDTFA-447 that was accepted by a dealer who then registered the car in California for you (see section 2); and mere non-use (“I never drove it in California”) without the delivery + first-functional-use + location documents above.

6. At the DMV Counter: the Two Forks

6.1 The rule that frames the counter

Use tax is due on all original registration and/or transfer applications for vehicles/vessels purchased from someone other than a licensed California dealer, manufacturer, or dismantler, unless the transaction is specifically exempted or CDTFA issues the applicant a CDTFA-111 (CR&TC §6422.1). DMV must withhold registration and/or transfer if the applicant does not pay the required use tax or submit a CDTFA-111. That sentence — “pay or produce a 111” — is the whole counter in one line.

6.2 The applicant fork (plain-English translation of §4.040’s table)

When it appears use tax is due but the applicant claims it is not due:

If you…	Then DMV…
Want the application processed immediately	Collects the use tax and any other fees due. You complete a REG 256 explaining why a refund is requested. (Refund route — see section 6.4.)
Do not want to pay the use tax due	Collects any other fees due on a report of deposit of fees (RDF) to avoid penalties. Advises you to contact CDTFA for a CDTFA-111.
Do not want to pay any fees	Returns the application to you, and advises you of the last penalty-free date to pay the fees due.
Need further information	Refers you to the CDTFA Taxpayer Information Section at 1-800-400-7115.
Live in an unincorporated area and are exempt from additional city use tax	Accepts a REG 256 with your residence address, a letter on city letterhead stating city use tax is not due, or a CDTFA-111.

Guidance on the fork, in the mover’s interest: the “pay now + REG 256 refund claim” route gets the car registered on time (protecting the 20-day clock) while the tax dispute runs its course; the “RDF + CDTFA-111” route avoids paying a tax you believe you do not owe, but leaves the registration incomplete until CDTFA answers — and the 20-day clock does not pause while you wait. This page does not recommend one route for everyone; it states the trade-off and lets the reader choose.

6.3 The CDTFA-111 clearance route (before registration)

If you claim the purchase is exempt or nontaxable, DMV may ask you to obtain a use tax clearance certificate from CDTFA before allowing registration without paying tax (CDTFA vehicles guide). Apply via CDTFA online services (“Request Use Tax Clearance for Registration with DMV/HCD” under Limited Access Functions) or submit form CDTFA-106, Vehicle/Vessel Use Tax Clearance Request, to a CDTFA field office or the Consumer Use Tax Section, MIC:37, PO Box 942879, Sacramento, CA 94279-0037. If approved, CDTFA issues CDTFA-111 (vehicle/mobilehome/commercial coach) or CDTFA-111-B (vessel). Take the original to DMV with the registration application.

Timing warning from Publication 52 (the detail movers miss): pay the DMV transfer fee on time even while a clearance request is pending — if you apply for a clearance, DMV returns the application and asks you to re-submit after CDTFA replies; a denied request means the tax is due to DMV, with a refund claim to CDTFA (Publication 117) as the dispute route. A pending clearance does not pause the registration deadlines.

The resident variant (Example F, section 3): a California resident who registers the car but keeps it out of state for the rest of the 12 months requests the CDTFA-111 so registration completes without paying use tax at that time — then must prove at month 12, with documentary evidence, that the vehicle did not enter the state during that period. Without that evidence, the presumption applies and tax is owed. The clearance is not an exemption; it is a deferral with a proof deadline at month 12.

6.4 If DMV got the amount wrong, or you paid and shouldn’t have

• Overpayment at DMV: contact CDTFA; claim a refund via CDTFA online services (“Claim a Refund for Tax Paid to DMV/FTB”) or form CDTFA-101-DMV, Claim for Refund or Credit for Tax Paid to DMV (vehicles guide).
• Underpayment: you reported a lower purchase price than the actual price — make an additional payment via CDTFA online services (“File a Return or Claim an Exemption for a Vehicle, Vessel, Aircraft, or Mobile Home”).
• Did not pay at DMV at all: report and pay directly to CDTFA (online “Pay Use Tax or File an Exemption” route, or in person at a field office), with purchaser/seller names and addresses, VIN, make/model/year, date of purchase, total purchase price, and registration address ready. Due date for the direct-to-CDTFA route: on or before the last day of the month following the month of purchase; penalty and interest begin to accrue once the due date has passed (vehicles guide). Keep this due-date sentence attached to the CDTFA-direct route — it is NOT the DMV 20-day registration deadline.
• Payment plans: Publication 52 notes CDTFA payment plans (weekly/monthly instalments) for use tax not paid at DMV, with a use-tax clearance issuable on approval and a later Notice of Determination for the liability plus penalty/interest. If you cannot pay in full, do not ignore the bill; CDTFA has a plan route. The Tax Collections Bureau number is 1-916-309-8150 (Publication 52).
• The out-of-state dealer who finances the California tax: DMV manual §4.040 has a specific procedure — when a California resident buys from an out-of-state dealer and finances the use-tax amount with the purchase price, the dealer issues a check payable to California DMV for the use-tax amount, and a REG 256 signed by the registered owner, marked “Payment of use tax, please allocate to CDTFA” in Section G, goes forward with the vehicle information. If the dealer did not do that, the buyer owes the tax at registration — ask the dealer for the check/REG 256 proof, do not assume.

6.5 Adjacent registration steps (one short section — not the page’s core)

First registration also needs the out-of-state title, the most recent out-of-state registration, VIN verification (REG 31), a smog certification where applicable, and California-compliant insurance. The full packet is on our buy-before-moving guide, and the first-registration smog rule — including why a nearly new car still needs the test — is on our smog guide for new residents. Book the smog check and the VIN verification in your first two days: they are the two third-party steps that slip past the 20-day clock.

7. Who Else This Affects — Carve-Outs in Short Form

Keep each of these to a short, CDTFA-sourced paragraph so the 12-month rule stays the star. The full treatment of each lives on the general use-tax page.

Active-duty military on official transfer orders. CDTFA vehicles guide + Publication 52: no use tax if the vehicle was purchased and delivered outside California before receiving official transfer orders to California, and the vehicle is brought in because of the transfer. Required documents: official transfer orders, purchase contract, title. Tax applies if delivery is taken in California or the vehicle is bought for California use after the orders. The full military registration treatment — including the narrow RTC §6249 wording (purchase prior to the effective date of reassignment) and the fact that there is no military exemption for vessels — is on our PCS orders guide.

Gift recipients. No use tax if the vehicle was given freely with no payment, trade, service, or assumed liability in return, and not as employer compensation (CDTFA vehicles guide). A signed statement from the former owner (with VIN/plate) plus the title supports the claim. Counter-examples CDTFA names: taking over loan payments = not a gift (tax on the balance assumed + any consideration); a corporate dividend car = not a gift. Note the §4.040 wrinkle: an applicant who gives or acquires a vehicle as a gift to or from a corporation or partnership must pay use tax or submit a CDTFA-111 — the individual-gift rule does not cover entity gifts.

Qualifying family purchases. No use tax on a purchase from a qualifying family member not in the business of selling vehicles: parent, grandparent, child, grandchild, spouse/registered domestic partner, or a brother/sister related by blood or adoption when both are minors — with documentation (birth certificates, marriage licence, adoption paperwork) plus title. CDTFA expressly excludes most step-relationships without a natural/legal-adoption link and post-divorce ex-spouse transactions.

Involuntary transfers. Court order, divorce property settlement, inheritance, or repossession of a vehicle you sold — no use tax, with court/repossession documents plus title. (§4.040 inheritance detail: Letters Testamentary / Letters of Administration = use tax or CDTFA-111 due; REG 5 survivorship transfers = not due — one sentence, link to the title-transfer pages for the full treatment.)

Leases and lease buyouts. Use tax is due on a lease buyout (the buyout amount); if no dealer handles it, the buyer pays at DMV; a resale to a third party within 10 days of acquiring title from the lessor is presumed a sale for resale (no tax to the buyout buyer) unless there was personal use first — and gifting instead of reselling kills that presumption (vehicles guide; DMV manual §4.040: tax on the balance owed at buyout; third-party sale within 10 days → tax from the third party only; after 10 days → tax from both). The full leased-car move treatment is on our leased-car guide.

Interstate-commerce operators. Section 2(c) — the commercial-miles test, not a personal-car strategy.

Trust transfers (one sentence, §4.040): use tax is not due when the current registered owner transfers the vehicle into or out of their own trust (or as a gift into/out of a trust), with a REG 256 from the owner — but use tax is due when a legal entity is the owner. Do not refer trust-transfer applicants to CDTFA for a clearance on an individual trust transfer.

8. New in 2026: SB 1406 and the Shell-Company Rule — Plus Two Different Rules

Two different rules — do not conflate them. The 365-day tax test and the 7,500-mile emissions rule are different rules with different jobs. The 7,500-mile rule (Vehicle Code §§43151–43152) is about whether a non-California-certified (“49-state”) vehicle can be registered at all: a California resident generally cannot register a 49-state vehicle with fewer than 7,500 miles, with exemptions claimed on REG 256F — including the exemption for a person who was a resident of another state when they acquired the vehicle and had it last registered there, which covers most new residents. The 365-day rule is about whether you owe use tax on a car you can register. One forum folk rule (“less than 8k miles or sold new less than 3 months ago = new car, so sales tax must be paid”) mashes the two together and gets both wrong. Keep them apart: 7,500 miles = can you register it; 365 days = do you owe use tax. The full 7,500-mile treatment is on our buy-before-moving guide and our smog guide for new residents.

Entity ownership, in one paragraph. A closely held corporation, partnership, limited partnership, limited liability partnership, or limited liability company counts as a California resident if 50% or more of its shares or interests are held by California residents (§6248(a)(1)(A), as amended by SB 1406, Chapter 1036, Statutes of 2026). A shell company is deemed a California resident if any shareholder, partner, member, or beneficial owner is a California resident (§6248(a)(1)(B)), where “shell company” means a closely held entity used for the purpose of evading taxes due — with evasion indicators including lacking a specific business activity, lacking a physical location outside California, failing to employ people / issue W-2s, and failing to file tax returns outside California (§6248(a)(1)(C)). Entity ownership does not, by itself, defeat the presumption — and a shell entity can make it worse.

9. Mistakes That Cost Movers Money

The 90-day ghost — where it actually comes from. One competitor page states that for motorhomes the presumption “can be overcome if the vehicle is functionally used outside of California for more than 90 days from the date of purchase.” The CDTFA 12-month FAQ’s “What is a binding contract?” section supplies the honest origin: the 12-month test provisions do not apply if a vehicle was purchased, or was the subject of a binding purchase contract entered into, during a time period when the 90-day test provisions were in effect — prior to October 2, 2004, and July 1, 2007 through September 30, 2008. The 90-day test is therefore a real rule — for purchases and binding contracts from those two historical windows. It is not the current test for an ordinary car bought on or after October 1, 2008. The correction in one box: “The 90-day rule you read about is real — and it expired for new purchases in 2008. If your car was bought after October 1, 2008, your test is 12 months.” That correction is more useful (and more linkable) than a flat denial, and it is the kind of precision no competitor page offers.

“Over 12 months = no tax” (the flat claim, still wrong). The verified rule is narrower: the §6248 presumption does not arise. Other provisions, other facts, and other taxes/fees may still apply. A popular forum summary (“over 12 months = no USE tax due; under 12 months = pay the difference”) is the oversimplification this guide replaces with presumption + evidence + credit. Example B in section 3 demonstrates the correct framing: “presumption off,” with the old registration kept as evidence — never “tax-free.”

“Tax is on the fair market value at the move date” (wrong). CDTFA’s base is the total purchase price (plus trades/debts assumed), not move-date value. A Quora answer stating FMV-at-move is wrong against CDTFA’s guides. The correction is the section 4 formula box.

“Tax paid to another state is irrelevant / you pay full California tax anyway” (wrong). The §6406 credit contradicts this. Answer with CDTFA’s $1,500/$2,000 → $500 example.

“A CDTFA-447 exempts the buyer” (wrong). The 447 relieves the seller’s collection duty when timely and in good faith; it does not relieve the buyer, and its own notice warns the buyer of the 12-month presumption. A dealer who accepts a 447/448 from a California resident and then registers the car in California for the buyer may itself be liable (CDTFA FAQ).

“Form an out-of-state LLC / keep Montana plates while living in California” (wrong as a blanket claim). §6248’s closely-held-entity (50%) and shell-company rules (now strengthened by SB 1406), plus the >half-time use/storage condition for nonresidents, contradict any blanket version of this claim. This guide describes the rules; it does not recommend the scheme.

Storing the car to “wait out the clock” (the storage trap). See Example G in section 3: the counter runs from the purchase date, storage does not pause it, and storage before entry is itself a CDTFA-referral trigger under §4.040.

“Fixing” a date on the application (the REG 256 trap). See section 5: any alteration to the date of entry or date of purchase requires a completed, signed REG 256; an application date that differs from the date of actual physical possession triggers a CDTFA referral. A “corrected” date without the form turns a clean file into a credibility problem.

“My dealer will handle the California tax” (half-true). Only under the §4.040 dealer-financed procedure (dealer’s check payable to California DMV + REG 256 Section G “Payment of use tax, please allocate to CDTFA”). If the dealer did not do that, the buyer owes the tax at registration. Ask the dealer for the check/REG 256 proof — do not assume.

“I registered the car, so the tax question is settled” (wrong both ways). Registration evidences intent to use in California (section 2) — it undercuts a “not for California use” claim. And registration does not settle the tax if the amount was wrong: overpayment → CDTFA-101-DMV refund claim; underpayment → additional payment via CDTFA online services (section 6.4).

Trusting a competitor’s fee table or rate. One law-firm cluster says the base registration fee is “approximately $71” in one article and $76 in another. A checklist site says use tax is “usually 7-10% of the car’s value” — wrong framing (purchase price, not value) and an unverified range. A content farm says California use tax is “currently 0%” — flatly wrong. This guide prints no fee figures at all (they are gated until verified on dmv.ca.gov) and only one rate: the verified 7.25% statewide base, plus district taxes at your registration address. For the fee side of the bill, see California DMV Fees.
