United States. Illinois, and the states that operate a real withholding at closing

Is there an Illinois exit tax when you move out of state?

Illinois levies no exit tax. It applies a domicile test, a part-year return and tax on Illinois-source income afterwards. The exit tax Illinois movers hear about is at least three unrelated things; the one real charge is New Jersey's.

Question 1

Which state are you leaving?

The mechanism differs completely by state, and the phrase exit tax describes different things in each.

What US states actually do when you leave, 2026

Last updated 2026-08-15

The phrase exit tax covers three unrelated things. A charge for leaving is what people picture. A prepayment taken from a nonresident at a property closing is real. A residency test that decides you never left is the expensive one. This table separates them.

What US states actually do when you leave, 2026
State	Is there an exit tax?	What actually applies	The mechanism	Where it catches people
Illinois	No	Residency by domicile, and tax on Illinois-source income after you leave	You are an Illinois resident if you were domiciled in Illinois for the entire tax year. A part-year resident files Form IL-1040 with Schedule NR	A move that did not change domicile. Domicile is where you reside and intend to return after temporary absences, and intent is read from the facts
Illinois, part-year	No	The split between the resident and nonresident periods	Include income received from any source while you were a resident, plus Illinois income received while you were not	The date of the change is doing all the work and is rarely evidenced at the time
New Jersey	No formal exit tax, and this is the mechanism people mean	An estimated Gross Income Tax payment on a nonresident's sale or transfer of New Jersey real property	The gain is multiplied by the highest Gross Income Tax rate, 10.75% effective 8-1-2004, and the payment must not be less than 2% of the total consideration stated in the deed	The 2% floor. A seller with no gain, or a loss, still pays 2% of the price at closing and waits for the return to get it back
New Jersey, the paperwork	Not a tax question at all	Which GIT/REP form reaches the settlement agent	GIT/REP-1 nonresident declaration at closing, GIT/REP-2 receipt for a prepayment before closing, GIT/REP-3 residency certification or exemption, GIT/REP-4 waiver, GIT/REP-4A corrective deeds	The form decides whether money is held back, and it is settled in the week before closing
New York, domicile	No	Residency by domicile, as in most states	You are a New York State resident if you are domiciled in the state	Nothing unusual. This limb behaves like Illinois
New York, statutory residence	No, and this is the expensive one	Residency by presence, regardless of intention	You are a resident if you maintain a permanent place of abode in New York State for substantially all of the taxable year and you spend 184 days or more in New York State	A genuine relocation plus a kept apartment plus frequent work trips. Intent is irrelevant to this test
Any state, after you leave	No	Continuing tax on income sourced to the state	Nonresidents are taxed on state-source income, which includes income from real property located in the state	Assuming that leaving ends the filing obligation. It ends the worldwide one, not the sourced one

Illinois levies no exit tax: its published guidance describes residency by domicile and a part-year return, not a charge triggered by leaving.
Illinois defines domicile as the place where you reside and the place where you intend to return after temporary absences, so a temporary absence does not change it.
An Illinois part-year resident includes income received from any source while a resident, plus Illinois income received while not a resident.
New Jersey requires an estimated Gross Income Tax payment on a nonresident's sale of New Jersey real property, computed as the gain times the highest rate of 10.75% effective 8-1-2004.
That New Jersey payment must not be less than 2% of the total consideration stated in the deed, so a seller with no gain still pays 2% of the price at closing.
New York treats you as a resident if you maintain a permanent place of abode in the state for substantially all of the taxable year and spend 184 days or more there, whatever your domicile.
Leaving a state ends its claim on your worldwide income, not on income sourced there, including income from real property located in the state.

How this was compiled, and how to cite it

Every row is taken from published state guidance read on 15 August 2026 and cited in full below: the Illinois Department of Revenue IL-1040 instructions and filing requirements for the Illinois rows, the New Jersey Division of Taxation GIT/REP FAQs and Technical Bulletin TB-57 for New Jersey, and the New York State nonresident and part-year resident guidance for New York. Figures are quoted as the states state them, including the 10.75% highest Gross Income Tax rate described as effective 8-1-2004 and the 184 day statutory residence count. Where this table says a state does not do something, it means the guidance cited describes no such mechanism, which is not the same as a search of the whole statute book: settlement practice in particular should be confirmed with the closing agent. No figure here is estimated, and no rate is carried over from another state by analogy. Rates and thresholds change on state legislative cycles, so the date this page was last checked is at the top of it, and it is the date the figures belong to.

The Illinois domicile test, and how a move actually gets proved

Illinois residency turns on domicile: where you reside and intend to return after temporary absences. What that means in evidence rather than in intention.

The states that really do take money when you leave

New Jersey's estimated GIT payment and New York's statutory residence test. What each one actually is, and why one is a prepayment rather than a tax.

The part-year return: which income belongs to which period

The year you move produces two tax periods with different rules. What goes in each, and the two items that most often land in the wrong one.

Leaving a state: the record to build while it is still easy

None of these items decides residency on its own. Together they are the record you would otherwise reconstruct years later from memory, under time pressure.

What it does and does not check

The 6 things it checks

Illinois, where there is no exit tax and the question is domicile
New Jersey's estimated Gross Income Tax payment at closing, which is what most people mean
New York's statutory residence test, and how a kept apartment undoes a move
Selling real property in the state you are leaving
Part-year returns and what income belongs to which period

Straight answers

Does Illinois have an exit tax?

No. Illinois publishes no charge triggered by leaving the state. You are a resident if domiciled there for the entire tax year; domicile is where you reside and intend to return after temporary absences. In the move year you file as a part-year resident on Form IL-1040 with Schedule NR. After that, Illinois taxes only Illinois-sourced income.

What do people mean when they talk about an exit tax?

Usually one of three unrelated things. A charge for leaving, not a feature of the states most often named. A prepayment from a nonresident seller at a property closing, which is real and mainly New Jersey and New York. Or a residency test saying you never left: the most expensive, as it taxes a full year of worldwide income.

What is the New Jersey exit tax?

Not a tax and not about leaving. A nonresident's sale or transfer of New Jersey real property requires an estimated Gross Income Tax payment at closing. It is the gain times the highest rate, 10.75% effective 8-1-2004, but not less than 2% of the deed's consideration. A seller with no gain still pays. The nonresident return settles the actual liability.

Can New York still tax me after I move away?

Yes, on two bases. One is domicile. The other, whatever your domicile, is a permanent place of abode in New York State for substantially all of the year plus 184 days or more there. A kept apartment plus frequent trips can mean a full resident year. Nonresidents still pay on New York source income, including real property.

How do I prove I changed my domicile?

With a pattern of small contemporaneous facts, not a declaration. It covers your home and the last one, family and children's school, driving licence, vehicle and voter registration, and professional licences. It also covers doctors, dentists, safe deposit boxes, club memberships and your payroll address. No single item decides it. Arrange it before the move, not after a notice.

Do I pay Illinois tax on selling my Illinois house after I leave?

The gain is Illinois-source income, taxed for a nonresident on Form IL-1040 with Schedule NR. The Illinois guidance cited here describes no closing payment or withholding like New Jersey's and New York's. So money may not be held back; confirm with the closing agent. Whether the sale falls in your resident or nonresident period changes where the return reports it.

Can two states both tax me in the year I move?

Yes, and it is normal. The state you left taxes worldwide income up to the domicile change and state-source income after; the new state taxes you from arrival. A credit generally relieves doubled income. Both treating you as resident for the same period is not normal: domicile is contested or statutory residence caught you. Take advice then.
