You end your state domicile by moving your life abroad and cutting the ties your old state counts, because no form does it for you. A Florida declaration of domicile only helps if you're settling in Florida. Skip the cutting and your old state can keep treating you as a resident.
Step 1: Find the state that counts you as a resident
Name the state where you're domiciled today, because that state decides whether you're still taxed after you leave. Domicile is the home you intend to return to whenever you're away. California's Publication 1031 describes it as the place where you voluntarily establish yourself and your family, not merely for a special or limited purpose.
New York uses the same idea: your domicile is the place you intend to be your permanent home (20 NYCRR 105.20(d)). Most people have one answer. If you moved states recently, check the old state too, because an existing domicile continues until you show a change.
Domicile is a state test. Your federal status runs on separate federal residency tests, the green card test and the substantial presence test.
Step 2: Move your life to India
Settle in India with the intent to stay, because a state keeps you as a domiciliary until you've both left it and landed somewhere else. A short stay abroad doesn't count. California treats you as a resident if you're domiciled there but outside the state for a temporary or transitory purpose.
Take Priya, an H-1B engineer in San Jose who accepts a role in Pune. She rents out her condo, keeps her California license, and plans "a couple of years" abroad. California can read that as a temporary absence, and a temporary absence leaves her a resident.
If you hold a green card, the immigration side matters too. Letting the card lapse doesn't end your US tax status, and keeping a green card after the move has its own rules.
Step 3: Decide if a declaration of domicile helps
File a Florida declaration of domicile only if Florida is where you're settling. Florida Statute 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, and the clerk charges a fee set under section 28.24.
The declaration records your intent, not the facts a state looks at. I wouldn't route a move through Florida just to file one, because paper without a real home, real time, and real ties is the weakest evidence you can offer.
If you're leaving from a state with no income tax, such as Florida or Texas, you've no state income-tax residency to end. This guide matters most if you're leaving from California, New York, or a similar state.
Step 4: Cut the ties your old state counts
Move the ties your old state looks at, one by one, and date each move. A kept home is a tie in its own right, so decide early whether you'll sell or rent it, and note that selling your US home carries its own tax rules.
Ties California counts
California's Publication 1031 lists the factors it weighs:
- Time: your days in California versus your days outside it.
- Family: where your spouse or registered domestic partner and your children live.
- Home: your principal residence, plus any real property and investments in the state.
- Documents: the state that issued your driver's license, where your vehicles are registered, and where you're registered to vote.
- Everyday life: your bank accounts, doctors, accountants, attorneys, and social ties.
The Franchise Tax Board says no one factor decides the question. Switching your license and voter registration while keeping the home and the family there won't carry the move.
The New York trap: a kept apartment
New York can treat you as a resident even after you've stopped being domiciled there. If you keep a permanent place of abode in the state and spend more than 183 days of the year in it, you're a statutory resident under Tax Law section 605(b).
If New York questions your move, the burden of proving the change is on you, and the evidence has to be clear and convincing. Keep dated records of where you slept as well as where your mail went.
Step 5: File the right last returns
File a part-year return for your old state and a dual-status return for the federal year you leave. In California, if you were a resident for only part of the year, you file Form 540NR.
On the federal side, if you've ended US residency and aren't a resident on December 31, you file Form 1040-NR marked "Dual-Status Return." You attach Form 1040 as the statement for your resident months.
The IRS dual-status rules set the due date at April 15 if you had wages with withholding, and June 15 if you didn't. The guides to your final US tax year and to Form 1040-NR walk through the federal return.
Step 6: Tell the people who withhold
Update your address with your 401(k) custodian, then ask it to stop withholding state tax once you've really left. Federal law bars a state from taxing retirement income of someone who isn't its resident or domiciliary, as that state's own law decides (4 U.S.C. 114(a)).
A 401(k) payout counts as retirement income under 4 U.S.C. 114(b)(1)(A).
The bar doesn't apply if the state still counts you as domiciled there, which is why steps 1 to 4 come first. Your 401(k) withdrawal strategy covers the federal and India side.
Start your timeline today
Write down your last day in the state, the date each tie moved, and where you slept most nights. I'd keep that record even if no state ever asks, because dates and receipts hold up where memory doesn't.

Frequently asked questions
Do I need a declaration of domicile in Florida before moving to India?
No. Florida's declaration under Florida Statute 222.17 is for people who have established a Florida domicile, and you file it with the clerk of the circuit court in your county. Moving abroad from another state doesn't require it, and it can't stand in for the ties a state actually looks at.
Which California form do I file in the year I move to India, Form 540 or Form 540NR?
File Form 540NR if you were a California resident for only part of the year. Form 540 is for full-year residents. The exit-year tax planning guide covers the federal side of the same year.
Will New York still tax me after I move abroad?
It can, if New York still counts you as a resident. That happens if you keep your domicile there, where you carry the burden of proving a change, or keep a permanent place of abode and spend more than 183 days in the state.
Estate tax is a separate question, covered in New York's estate tax cliff.
Can my old state tax my 401(k) after I move to India?
Not if you're no longer its resident or domiciliary. Under 4 U.S.C. 114, a state can't tax retirement income of someone who is neither, as that state's own law decides. The catch is the domicile test itself, so finish the ties in step 4 first.
Does California's 546-day safe harbor end my residency if I move to India for work?
It can, but only if you're outside California under an employment-related contract for at least 546 consecutive days. It doesn't apply if you have intangible income above $200,000 in a year the contract is in effect, or if your main purpose in leaving is avoiding California income tax, according to Publication 1031.
