US State Tax Residency for Digital Nomads: Severing Domicile Without Getting Audited

The short answer

Digital nomad state tax residency is settled by state law, not by where your plane landed. Leaving the country does not end a state's claim on you. A state keeps taxing you as a resident until you can show you abandoned your old domicile and established a new one somewhere else. Day counts matter less than documents.

California and New York publish the rules their auditors work from, and neither treats a departure as self-executing. Which government taxes your income at all is a separate layer, covered in where you owe tax as a nomad. This article is about the state that still thinks you live in it.

Federal relief does not bind the states

The Foreign Earned Income Exclusion is a federal provision, and a generous one: under Revenue Procedure 2025-32, the exclusion in section 911(b)(2)(D)(i) is USD 132,900 for taxable years beginning in 2026, up from USD 130,000 for 2025 under Revenue Procedure 2024-40. IRS Notice 2026-25 puts the matching cap on housing expenses at USD 39,870, or 30 per cent of the exclusion. None of it binds a state.

California is explicit. FTB Publication 1031 for 2025, the Franchise Tax Board's guidelines for determining resident status, states that "California does not allow a foreign tax credit or a foreign earned income exclusion," and tells filers who claimed it federally to add the excluded amount back on Schedule CA (540NR). It extends the same logic to treaties: "Generally, unless the treaty specifically excludes the income from taxation by California, the income is taxable."

New York goes the other way. Its instructions for Form IT-203 say that if you are entitled to a federal exclusion from foreign earned income under section 911, "you are also allowed to claim it on your New York State income tax return in the Federal amount column," with federal Form 2555 attached.

The same Form 2555 therefore produces a state bill in one state and none in the other, and which federal election you made changes the state arithmetic too. We compare the two in FEIE against the Foreign Tax Credit.

Domicile and statutory residence are two separate tests

States run two independent routes to resident status, and a nomad can fail either.

Domicile is intent-based and singular. The New York Department of Taxation and Finance defines it as "the place you intend to have as your permanent home" and adds that "you can only have one domicile." The California FTB calls it the place you establish "with a present intention of making it your true, fixed, permanent home," and "the place where, whenever you are absent, you intend to return."

Statutory residence ignores intent and counts. Under New York's framework, someone domiciled elsewhere is still a New York resident if they maintain a permanent place of abode in the state for substantially all of the taxable year and spend "184 days or more in New York State during the taxable year." The Department's bulletin defines that abode as a residence maintained "whether you own it or not" and "suitable for year-round use," and reads "substantially all of the taxable year" as more than eleven months.

For nomads the trap is the abode, not the calendar: leave a lease running and the day count is all that stands between you and resident status. The Department is also clear about who holds the paperwork. A non-domiciliary keeping a New York abode must retain "adequate records to substantiate the fact that such person did not spend more than 183 days of such taxable year within New York State."

Both tests differ structurally from the country-level rules in how tax residency is actually decided. A country can usually be left by leaving. A domicile cannot.

California does not treat absence as departure

California is the state nomads most often misread, and the FTB says why in one sentence: "any individual who is a resident of California continues to be a resident when absent from the state for a temporary or transitory purpose."

Publication 1031's Example 3 is the warning. A taxpayer declares Nevada residency and moves their bank accounts there, but keeps a California home, spends six or seven months a year in it and retains social club and business connections. The FTB's determination: "Your declaration of residency in Nevada does not establish residency in that state."

One bright-line route out exists, and it is narrow. The 2025 publication's safe harbor provides that an individual domiciled in California who is outside the state under an employment-related contract "for an uninterrupted period of at least 546 consecutive days will be considered a nonresident," unless they have intangible income exceeding USD 200,000 in any taxable year the contract is in effect, or the principal purpose of the absence is to avoid personal income tax. Return visits of no more than 45 days in a covered year count as temporary, and an accompanying spouse or registered domestic partner qualifies on the same 546-day basis.

Note the precondition: an employment-related contract. The FTB adds that "individuals not covered by the safe harbor determine their residency status based on facts and circumstances" — where a self-employed nomad with clients rather than an employer sits. Whether a consulting arrangement reads as an employment-related contract is worth paying a cross-border accountant to answer before you file, not after a notice arrives.

Absent the safe harbor, the FTB requires all three of "abandonment of your prior domicile," "physically moving to and residing in the new locality," and "intent to remain in the new locality permanently or indefinitely as demonstrated by your actions."

New York publishes two exits for its own domiciliaries

New York is unusual in writing a nomad-shaped exit into its rules. Its Nonresident Audit Guidelines describe two provisions, under Tax Law section 605(b)(1)(A) and 20 NYCRR 105.20(b), under which a New York domiciliary is not deemed a resident at all.

The 30-day rule requires no permanent place of abode in New York during the year, a permanent place of abode outside New York for the whole year, and not more than 30 days spent in the state. The 548-day rule is the one long-term travellers should know. It requires that within any period of 548 consecutive days the taxpayer is present in a foreign country or countries for at least 450 days; that during that period the taxpayer, their spouse (unless legally separated) and their minor children are not present in New York for more than 90 days; and that presence in New York during the non-resident portions of the bookend tax years is pro-rated against that 90-day allowance. Both full and part days count.

Meet either test continuously and the Department treats you as a non-resident; fail a condition and you are taxed as a resident, with the burden of proof on you.

What actually severs a domicile

New York's audit guidelines are the clearest published account of how this gets decided, because they say what is weighed first. The analysis turns on five primary factors — Home, Active Business Involvement, Time, Items Near and Dear, and Family Connections — plus subordinate other factors, requested "only when a basis for New York domicile, using the primary factors, is found to exist."

Those other factors are what nomads fix first, and California's published list largely matches them. The pattern decides, not the paperwork. Publication 1031 warns that "it is the strength of your ties, not just the number of ties, that determines your residency," and New York's guidelines caution that a taxpayer "may be able to change his voter registration, auto registration, or driver's license to another state for convenience purposes, while never intending to change domicile." Quoting the Tax Appeals Tribunal in Matter of Colin and Delma Getz, they add that formal declarations such as voter and car registration "are less persuasive than informal acts which demonstrate an individual's general habit of life."

Read as a checklist, the items generally need to point the same way.

• Driver's licence and vehicle registration, surrendered in the old state
• Voter registration, with a record of actually voting in the new one — New York's auditors are told to ask about primaries and school board elections, not just November
• Banking, cards and "the origination point of your financial transactions," in the FTB's phrase
• Mailing address and mail forwarding
• Professional licences, club and gym memberships
• Doctors, dentists and where dependants live and go to school
• Where possessions, valuables and safe deposit boxes sit, and what wills and leases name as your domicile
• The old home sold or let at arm's length, not held available for you

Establishing a new domicile in a no-income-tax state

The nomad route is usually South Dakota, Texas or Florida. Each publishes its mechanics.

South Dakota is the most explicit about full-time travellers. Its Department of Public Safety states that an applicant must have a physical South Dakota residential address, live full time in an RV or camper, or travel full time for work. Using a mail forwarding service triggers a notarised Residency Affidavit signed under a perjury statement. The Department also asks for a named receipt from a South Dakota hotel, campground or RV park proving one night's stay within the last year, plus a document showing the personal mailbox address — and says virtual addresses are not accepted.

Texas levies no individual income tax, and the bar is constitutional: Article VIII, section 24-a of the Texas Constitution, added by House Joint Resolution 38 and approved by voters on 5 November 2019, provides that "the legislature may not impose a tax on the net incomes of individuals." The Comptroller describes the state's franchise tax as a "privilege tax" on each taxable entity doing business in Texas — a business tax, not a tax on individual income. Florida offers a formal declaration — Florida Statutes section 222.17 lets a person who has established a Florida domicile file a sworn statement with the clerk of the circuit court in their county declaring the Florida home as their permanent residence, signed under oath and recorded by the clerk. The statute preserves other means of proving domicile rather than replacing them.

Here is the limitation nobody selling mail forwarding mentions: a mailbox is an "other factor," and other factors are subordinate. A South Dakota mailbox, a Texas licence and a Florida declaration evidence that your intent changed. They are weak on their own if your spouse, children, apartment, bank branch and physical presence still point at California. Proving where you are resident instead is the harder half, covered for the international case in our guide to getting a tax residency certificate.

The no-income-tax states, with their caveats

Nine states levy no broad-based individual income tax as of October 2026, though the Tax Foundation's 2026 tables count eight with "no individual income tax at all" and list Washington separately because it "taxes capital gains income only." Three carry asterisks.

What triggers a residency audit, and what the auditor reads

New York's Nonresident Audit Guidelines name two patterns its auditors are pointed at. One is a claimed change of domicile "immediately prior to the occurrence of a large capital gain," where "often the only change in lifestyle demonstrated by the individual is the fact that a substantial gain was realized." The other is a New York address that survives the move: auditors are told to check the living-quarters question on Forms IT-203 and IT-201, the address on the W-2 or IT-2, and the Real Estate Transfer Tax file.

The burden then falls on you. New York's Nonresident Audit Guidelines state that "the burden of proving a change of domicile is upon the party asserting the change," and that the evidence "must be clear and convincing" under Bodfish v. Gallman — a taxpayer historically domiciled in New York who claims a change "must be able to support his intentions with unequivocal acts."

On day counts, the guidelines name the records: a taxpayer may be asked for "credit card receipts, phone bills, or other information to identify where the taxpayer was during a specific period," and diaries and logs are verified by random sampling and test checking. They also warn about "false indicators" that wrongly turn a non-New York day into a New York day, such as a child's credit card purchase in the state.

A contemporaneous day log — date, city, country, corroborated by boarding passes, accommodation receipts and card statements — kept from the departure date rather than from the arrival of a notice is what those requests get tested against. New York's guidelines are reasonable about gaps, telling auditors not to count an undocumented weekend between two documented out-of-state days as in-state days, but that only helps if there is a pattern to interpolate from.

The year you leave: part-year returns

The departure year almost always carries a filing obligation, sometimes two. California's rule is stated plainly in Publication 1031: "part-year residents of California are taxed on all income received while a resident and only on income from California sources while a nonresident," on Form 540NR, with Schedule CA (540NR) reconciling the federal and California figures. New York splits the year on Form IT-203, whose instructions tell part-year residents to include in the New York State amount column the part of the federal amount received while resident, and flag that the columns diverge for taxpayers subject to special accruals.

Two details set the size of that bill: the date your residency actually ended, and the sourcing of income that straddles it — a bonus, an equity vest, a house sale. The sequencing genuinely changes the number, and it is worth paying an accountant who does multi-state and cross-border work to review the departure year before you file.

The bottom line

State tax residency is a documentation exercise dressed up as a travel decision. The two states that matter most to nomads publish their own playbooks — Publication 1031 and the Nonresident Audit Guidelines — and both say the same thing: intent counts, intent is proved by acts, and the acts have to be consistent.

So the whole list matters more than any single item on it, and contemporaneous records are what demonstrate the pattern. Neither state publishes a timetable for completing the move, which is one more reason the sequencing belongs in front of an accountant. Then layer the federal and international picture on top; we map the full stack in our nomad tax residency guide. Because a residency audit is argued on facts, the specifics of your own case belong in front of a cross-border accountant before you change anything.

Frequently Asked Questions

Do digital nomads pay state taxes?

Many do without realising it. State residency is decided under state law, independently of federal rules and of any foreign country's claim. FTB Publication 1031 states that a California resident "continues to be a resident when absent from the state for a temporary or transitory purpose," so a nomad who kept a California domicile still owes tax there on worldwide income. One who severed it and established a new domicile in a no-tax state generally does not.

Can California still tax me if I live abroad?

Yes, if California remains your domicile. The FTB's own example treats a taxpayer who declared Nevada residency but kept a California home, social clubs and business connections as a continuing resident. The published exception is the safe harbor: an uninterrupted absence of at least 546 consecutive days under an employment-related contract, subject to the USD 200,000 intangible income limit.

Does a mail forwarding address establish residency?

Not on its own. South Dakota's Department of Public Safety accepts a personal mailbox address as one supporting document for full-time travellers, alongside a notarised Residency Affidavit and a receipt proving one night's stay in the state in the past year, and says virtual addresses are not accepted. New York's guidelines treat addresses and registrations as subordinate "other factors" a taxpayer controls at will, which is why a mailbox alone rarely carries an audit.

Which states have no income tax?

Nine levy no broad-based individual income tax as of October 2026: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. Washington's Department of Revenue still taxes long-term capital gains at 7 per cent above a standard deduction, plus 2.9 per cent above USD 1 million from tax year 2025, and Senate Bill 6346, signed on 30 March 2026, adds a 9.9 per cent tax on Washington income above USD 1 million from 1 January 2028. Tennessee's Hall income tax ended for periods beginning on or after 1 January 2021; New Hampshire's Interest and Dividends Tax was repealed for periods beginning after 31 December 2024.

What triggers a state residency audit?

New York's Nonresident Audit Guidelines point auditors at a claimed change of domicile "immediately prior to the occurrence of a large capital gain," and at New York addresses and living quarters still showing on the return, the W-2 or the Real Estate Transfer Tax file. They put the burden of proving a change of domicile on the taxpayer, require "clear and convincing" evidence, and describe auditors requesting credit card receipts and phone bills. Which jurisdiction can tax you at all is a prior question, covered in how tax residency is actually decided.
