A California residency audit is decided on bank statements and card swipes, not on the client’s story. The Franchise Tax Board (FTB) builds a calendar of where the client physically was. Declared intent comes a distant second.
Here is what the law asks, what the auditor pulls, and what the exit-year file should hold.
Two ways to be a resident
Revenue and Taxation Code Section 17014(a) defines a resident in two limbs. First, “every individual who is in this state for other than a temporary or transitory purpose”. Second, anyone “domiciled in this state who is outside the state for a temporary or transitory purpose”.
The second limb follows a client out of the state. Subdivision (c) adds that a resident “continues to be a resident even though temporarily absent”. (Domicile is the one permanent home a person intends to return to, however long they are away.)
So the client who left has two things to prove. That domicile moved, and that the absence is not temporary or transitory. Both are questions of fact.
“Temporary or transitory” means closest connections
The statute does not define the phrase. The FTB’s guide to resident status, Publication 1031, supplies the test. “You are a resident of the place where you have the closest connections.”
The State Board of Equalization said the same in the Appeal of Bragg (2003-SBE-002). With contacts in more than one state, residence is the state of “the closest connections during the taxable year”. The decision “cannot be based solely on the individual’s subjective intent”; it rests on objective facts.
The FTB’s own Residency and Sourcing Technical Manual restates this for its auditors. The question is whether the taxpayer “substantially severed his California connections” or kept them “in readiness for his return”. Every document request is built around that frame.
The factors, and why counting them fails
Bragg lists nineteen factors. Where the residential real property is, and its size and value. Where the spouse and children live, and where the children attend school.
Which residence carries the homeowner’s property tax exemption. Telephone records, meaning “the origination point of taxpayer’s telephone calls”. Days in California versus days elsewhere, “and the general purpose of such days”.
Where the returns are filed and what state they claim. Bank accounts, and “the origination point of the taxpayer’s checking account transactions and credit card transactions”. Then memberships, vehicles, driver’s license, voting history, doctors, lawyers, employment, business interests and affidavits.
The Board was blunt that the list is a guide, not a scorecard. The weight of any factor “depends upon the totality of the circumstances”. The focus is not whether the taxpayer “satisfies a majority, or even a significant number, of the factors”.
Publication 1031 puts it in one line. “It is the strength of your ties, not just the number of ties, that determines your residency.” The manual groups them in three: physical presence and property, personal and professional associations, registrations and filings.
One presumption to know: more than nine months in California in a year, and you are presumed a resident. It can be rebutted, and the manual notes that under nine months proves nothing.
What the auditor actually pulls
The FTB’s audit page says it “will contact you in writing” if a return is under audit. It then issues Information Document Requests, or IDRs. (An IDR is a written list of records the auditor wants, due in 30 days.)
Before the first letter, the auditor has done what the manual calls “skip tracing”. It names the sources: DMV records, the internet, Lexis/Nexis, Zillow.com and prior audit reports. The client’s public footprint is in the file before the client knows there is one.
Then come the financial records. The manual calls them “the most useful, but most sensitive, documents obtained during a residency audit”. Bank statements, canceled checks and card statements are entered into a database, transaction by transaction.
From those the auditor prepares “calendars to reflect a taxpayer’s physical presence for each year under audit”. Grocery stores, cleaners, hair salons and gas purchases count as presence at the payee’s location. A mailed mortgage or utility payment does not.
Why “I moved to Nevada” loses on documents
Publication 1031 has the case ready-made. A taxpayer declares Nevada residency, keeps the California home, and still spends six or seven months there. Bank accounts move to Nevada; the social club and business connections stay.
The FTB’s answer: “Your declaration of residency in Nevada does not establish residency in that state.” Closest connections are to California, so the absence is temporary or transitory. Full resident, taxed on all income.
The manual tells auditors why the paperwork alone does not help. New voter registration, or a stated intent to live elsewhere, are “mere formalisms” and “not controlling”. A moved bank account carries no weight if “the transaction pattern remains the same after the change”.
Bragg itself cut the other way. Mr Bragg kept home, family and doctors in California and argued he had stayed. The Board held he had left for Arizona: his days, work and returns said so.
The burden sits on the client
Bragg states the rule. The FTB’s residency determinations “are presumptively correct, and the taxpayer bears the burden of showing error”. The burden of proving a change of domicile “is on the party asserting such change”.
And the tie goes to California. If doubt remains after all the facts are in, “the domicile must be found to have not changed”. The FTB generally has four years from filing to assess, so the records must last that long.
The FTB will not help in advance. Publication 1031 says it “will not issue written opinions” on residency, because it is “a question of fact, not law”. There is no ruling to request, only the file.
The exit-year file
Build it in the year the client leaves, in the auditor’s own three categories. Physical presence first: a day-by-day calendar for the exit year and the year after. Tie it to card statements and boarding passes, and name the purpose of each California trip.
Property next. The closing statement or lease on the new home, and the sale or listing of the California one. The letter canceling the California homeowner’s exemption.
Associations: the spouse’s and children’s addresses, school enrollment letters, new doctors, club resignations and new memberships. Registrations: the new driver’s license, vehicle registrations and voter card, each dated. The last California return says part-year; the new state’s return says resident.
Then a short memo, written at the time, applying the Bragg factors to these facts. Name the ties that stayed and why. A memo written that year beats a reconstruction four years later.
If the client is abroad under a long employment contract, check the 546-day safe harbor first. We cover it in our article on California and the foreign earned income exclusion.
What this means for your firm
A California exit return is an evidence problem, not an allocation problem. The evidence has to exist before the question is asked. Our state tax guide for expats covers the client side; our multi-state allocation article covers splitting the year.
This is the kind of return we prepare for firms. The Desk’s record: 5,300+ tax returns filed in the last 4 seasons. One enrolled agent prepares, and a second reviews every file before it leaves.
For a California exit year, that means a Form 540NR with the residency dates supported. A day count reconciled to documents. A Bragg-factor memo in the workpapers, written the year it happened.
You review, you sign, you file. We never sign a return or e-file. Your firm stays preparer of record.
We work under ISO/IEC 27001:2022 certification; the platform logs who touched what. How we work with firms is at for expat tax firms, starting with the first five returns. Pricing is on the pricing page.
