Domicile vs. Statutory Residency: Which State Taxes Your Whole Freelance Income? (Guide for Freelancers With Two Homes)

Published: October 6, 2026 · Reading time: 12 min

TL;DR: A state taxes all of a resident's income, wherever it was earned, and taxes a nonresident only on income sourced to the state. So which side of that line you land on is the biggest state-tax question a freelancer with two homes has. The line is drawn by a legal test, and there are two different tests. Domicile asks where you intend your permanent home to be. Statutory residency ignores intent: in New York, a person who maintains a permanent place of abode in the state and spends more than 183 days there is a resident "whether or not domiciled" there. You can have only one domicile, but you can be a resident of a state that is not your domicile. In our worked example, the same $120,000 of profit is taxed on $62,608.70 at 175 days and on $120,000 at 190 days, a $2,869.57 difference in state tax at an illustrative 5% rate (New York City resident tax, which this example leaves out, would widen it). Not every state uses a general day count: California weighs your closest connections. Keep a dated record of where you were.

If you live and work in one place, you will never think about this. If you keep a second apartment, spend winters somewhere warm, or "moved" to a no-income-tax state and still return to the old city for clients, you are in the one situation where a single word on your tax return, "resident," can cost thousands of dollars.

That word sounds like it describes where you live. It does not. It names the result of a test, and the test is written by each state. This guide compares the two tests that matter, shows where they diverge, and explains what to track so you can prove your answer.

For the basics of state filing (resident returns, nonresident returns and credits), start with state income tax for multi-state freelancers. This post goes one level deeper: how the state decides which of those returns you file in the first place.

Why "Resident" Matters So Much

A state's power to tax you comes in two sizes:

• Resident: the state taxes your income from all sources, including clients in other states and work you did elsewhere.
• Nonresident: the state taxes only income sourced to it, which for most freelancers means income from work physically performed there.

California's residency guide puts the resident side in one sentence: "As a resident, your income from all sources is taxable by California." For a freelancer whose clients are scattered across the country, being a resident of the wrong state means being taxed there on money earned somewhere else entirely.

Your federal return does not care. Your Schedule C and self-employment tax come out the same whichever state you live in. Residency only decides which state returns you file and how large they are.

The Label Is Not the Test

The everyday words, "home," "I live in Florida," "my address," are labels. Neither state-law test below is satisfied or defeated by a label:

• Saying you live somewhere does not make it your domicile. New York's regulation says your declarations "will be given due weight, but they will not be conclusive if they are contradicted by such individual's conduct."
• Not owning a home in a state does not prevent statutory residency, because a leased apartment can be a permanent place of abode too. And having a home there does not by itself make you a resident, because the day count still has to be met.
• Being domiciled elsewhere is not a defense to statutory residency. The statute says so in terms.

So the useful question is not "where do I live?" but "what does each state's definition say, and which of my facts does it count?"

The Two Tests, Side by Side

I fetched the New York statute (Tax Law §605(b)(1)), New York's implementing regulation (20 NYCRR 105.20) and California's Franchise Tax Board residency guide (FTB Publication 1031, 2025 edition) directly and searched the raw text for every quotation below. New York is the best-known example of a hard day-count rule, which is why it is the main illustration. California is included because it shows that a day count is not universal.

Test 1: Domicile (intent)

New York's regulation, 20 NYCRR 105.20(d)(1), defines it this way: "Domicile, in general, is the place which an individual intends to be such individual's permanent home," and the same sentence continues, "the place to which such individual intends to return whenever such individual may be absent."

Three features make it unlike the day-count test:

1. You get exactly one. Subdivision (d)(4): "A person can have only one domicile. If a person has two or more homes, such person's domicile is the one which such person regards and uses as such person's permanent home." The regulation adds that "the length of time customarily spent at each location is important but not necessarily conclusive."
2. It sticks until you replace it. Under (d)(2), a domicile "continues until the individual in question moves to a new location with the bona fide intention of making such individual's fixed and permanent home there," and "no change of domicile results from a removal to a new location if the intention is to remain there only for a limited time."
3. You carry the burden of proving a change. "The burden is upon any person asserting a change of domicile to show that the necessary intention existed." Voting and registering help but are "important but not necessarily conclusive, especially if the facts indicate that such individual did this merely to escape taxation."

A person domiciled in New York is a resident unless one of the statutory exceptions applies. The main one: the person maintains no permanent place of abode in New York, maintains one elsewhere for the entire year, and spends no more than 30 days in New York in the year (Tax Law §605(b)(1)(A)(i); 20 NYCRR 105.20(b)(1)). All three conditions must be met.

Test 2: Statutory residency (abode plus days)

Statutory residency does not ask where you intend to live. Tax Law §605(b)(1)(B) makes a resident of an individual "who maintains a permanent place of abode in this state and spends in the aggregate more than one hundred eighty-three days of the taxable year in this state, whether or not domiciled in this state for any portion of the taxable year" (armed forces members in active service are excepted).

The regulation adds a "substantially all of the taxable year" condition in 105.20(a)(2): the person "maintains a permanent place of abode for substantially all of the taxable year (generally, the entire taxable year disregarding small portions of such year) in New York State and spends in the aggregate more than 183 days of the taxable year in New York State."

Two definitions do the work:

• Permanent place of abode, 105.20(e)(1): "a dwelling place of a permanent nature maintained by the taxpayer, whether or not owned by such taxpayer, and will generally include a dwelling place owned or leased by such taxpayer's spouse." A rented flat counts. A spouse's lease can count. But "a mere camp or cottage, which is suitable and used only for vacations, is not a permanent place of abode."
• A day, 105.20(c): "presence within New York State for any part of a calendar day constitutes a day spent within New York State," except presence "solely for the purpose of boarding a plane, ship, train or bus for travel to a destination outside New York State, or while traveling through New York State to a destination outside New York State."

The same subdivision puts the proof on you: a person domiciled outside New York who keeps a permanent place of abode in New York and claims to be a nonresident "must keep and have available for examination by the Department of Taxation and Finance adequate records to substantiate the fact that such person did not spend more than 183 days."

A third approach: closest connections, not a general day count

California's FTB Publication 1031 defines a resident as an individual who is either "Present in California for other than a temporary or transitory purpose" or "Domiciled in California, but outside California for a temporary or transitory purpose." The underlying theory, it says, is "that you are a resident of the place where you have the closest connections," and "it is the strength of your ties, not just the number of ties, that determines your residency." There is a presumption, not a bright line: "You will be presumed to be a California resident for any taxable year in which you spend more than nine months in this state."

The publication also states directly that California "makes a distinction" between domicile and residence "as two separate concepts," so "you may be domiciled in California but not be a California resident or you may be domiciled in another state but be a California resident for income tax purposes."

California does carve out one narrow safe harbor for domiciliaries who work outside the state: under the publication, a California domiciliary outside California under an employment-related contract for an uninterrupted period of at least 546 consecutive days is generally treated as a nonresident, with limits on return visits and on intangible income. Whether it reaches a self-employed person is a question for a preparer, so do not assume it does.

(One caution on dates: the California guide I searched is the 2025 edition. Check the current edition before relying on any detail.)

Comparison Table

The Decision Framework: Four Questions in Order

You are not choosing between these tests; each state applies its own to you. What you can do is find out which way the facts point before the year ends, while a change is still possible.

1. Where is my domicile? Pick the one home you regard and use as your permanent home, and make your conduct match: where your family lives, where your belongings are kept, where you spend holidays, where your license, voter registration and bank accounts are. If your facts are split, expect a state that wants to tax you to argue that your conduct points to it.

2. Do I keep a dwelling in any other state? An owned home, a lease, a spouse's lease, a long-term rental: each can be a permanent place of abode where the state uses that concept. A vacation cabin used only for vacations is not.

3. How many dates did I physically spend in each such state? Count distinct calendar dates, using the state's counting rule, not nights. In New York, arriving at 11 p.m. is a day.

4. Which state could claim me, and does either offer a credit? If your domicile state and a statutory-residency state both treat you as a resident, both can tax all of your income. See the credit section below.

Worked Example: Dana's Two Homes and Fifteen Days

Dana is a freelance video editor. She is domiciled in Florida, which does not tax individuals' income (Article VII, section 5(a) of its constitution bars any state tax on the income of natural persons above the amount creditable against a similar federal tax, and the state levies none), and she leases a Brooklyn apartment year-round. Her 2026 net profit is $120,000. For the arithmetic, assume:

• She performs work in New York on 120 of her 230 working days in the year, so New York would source 120/230 of her profit if she is a nonresident. Real nonresident sourcing rules are a separate analysis, and the multi-state post linked above covers how sourcing works.
• New York would tax at an illustrative 5% effective rate. That is a placeholder to show the shape of the result, not New York's rate schedule.

Fifteen more dates in New York (190 minus 175) move Dana from a nonresident taxed on $62,608.70 to a resident taxed on $120,000, an extra $57,391.30 of taxable income and $2,869.57 of tax at the illustrative rate. Because Florida taxes nothing, there is no home-state credit to offset it. The figures are state tax only. New York City applies the same residency test to its own resident income tax, so the resident column would also add city resident tax on the full $120,000 while the nonresident column owes none, and the real gap is larger than $2,869.57.

Three details make this realistic rather than contrived:

• Dates, not nights. Dana slept in Brooklyn on 168 nights, a number she would quote from memory. Her calendar shows 190 distinct dates in New York, because day trips and the day she leaves each count as a full day. That is a 22-day gap between the number she remembers and the number the regulation counts.
• Her Florida domicile is no defense. The statute reaches an individual "whether or not domiciled" in New York.
• Scenario A is not tax-free. A nonresident still owes New York tax on New York-sourced income. Being under 183 days changes which of the two sizes of tax claim applies, not whether there is one.

If Dana wanted to avoid the statutory test altogether, the options are on the abode side (no permanent place of abode in New York) or the day side (stay at or under 183). The regulation's counting rules mean a margin of safety is a number she tracks in advance, not a figure she reconstructs in April.

What the Exceptions Do Not Buy You

The relief provisions in this area are narrower than they sound, and two of them look similar to each other.

• The 30-day exception is for domiciliaries, and it requires that you keep no New York abode. It lets a person who is domiciled in New York avoid resident status, but only if all three conditions are met, including that the person "maintains no permanent place of abode in New York State during such year." Keep the apartment, and the 30-day rule is unavailable however few days you spend there.
• The 183-day line is not a safe harbor for domiciliaries. It limits the statutory prong, which applies to people who are not domiciled in the state. Spending 120 days in New York does not make a New York domiciliary a nonresident.
• Staying at or below 183 days does not end the state's claim. If you are not domiciled in New York, it means you are a nonresident of New York, who still owes tax on New York-sourced income.
• Registering to vote does not, by itself, change your domicile. The regulation treats registration as "important but not necessarily conclusive," and discounts it where the facts suggest it was done "merely to escape taxation."

When Both States Can Tax the Same Dollar

If your domicile state treats you as a resident and another state treats you as a statutory resident, both can claim all of your income. New York's credit provision, Tax Law §620(a), allows a resident a credit "for any income tax imposed on such individual for the taxable year by another state of the United States ... upon income both derived therefrom and subject to tax under this article."

Read carefully, that credit covers tax the other state imposes on income derived from that other state. It does not, on its face, cover tax your domicile state imposes on income that has no connection to it. For a freelancer paid for work done in the two states, most of the income has a home in one of them, which is why the double-tax risk is real but often partial. The gap is income sourced to neither state, or sourced differently by the two states.

This is an area to have both returns modelled by a CPA or EA before you file. The cost of the model is small next to the stakes.

Common Mistakes to Avoid

• Counting nights instead of dates. The New York regulation counts "any part of a calendar day." Count from a calendar.
• Treating a "move" as complete when the paperwork changes. A new license and voter registration do not outweigh a retained home, family and business ties in the old state.
• Forgetting the spouse's lease. In New York, a permanent place of abode "will generally include a dwelling place owned or leased by such taxpayer's spouse."
• Assuming one state's rule applies everywhere. California has no 183-day count; its test turns on temporary or transitory purpose and closest connections, with a nine-month presumption.
• Assuming "nonresident" means "no tax." A nonresident still owes tax on income sourced to the state, typically work done there.
• Reconstructing days after the audit letter. The regulation puts the burden on the person claiming nonresident status to "keep and have available" the records. Memory is not a record.
• Forgetting the federal return is unchanged. Your state choice does not alter Schedule C, so keep your normal records for each deduction regardless.

How CentSense Helps

Residency is proved with dates and places, and a freelancer's expense records are full of both.

• Scan receipts with AI, so each receipt is saved with its merchant and date, a dated trail that can corroborate where you were on a given day
• Categorize expenses to Schedule C lines, so your net profit, the number every state return starts from, is clean and defensible
• Log business miles by date (Solo plan), which doubles as a dated record of business travel. Note that CentSense's mileage export applies a single annual rate and does not apply the July 1, 2026 split (72.5 cents through June 30, 76 cents from July 1) to each trip, so value each trip at the rate for its date
• Export a CSV for your CPA, who can match your dated entries against a day-count calendar when modelling two state returns

CentSense is not a residency tracker, and it does not count days for you. Keep a separate calendar of where you slept and worked, and use your receipts and mileage entries as supporting evidence for it. The better your dated records, the less you rely on memory.
