About Exit Tax Estimator
Which states actually charge you for leaving, and which ones only look like they do
What is on this site
One question, "illinois exit tax", answered with a checker that works on the page with no account, 4 guides on the questions around it, a data table you can cite (the figures and their method), and the sources every figure rests on.
- 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.

Exit Tax Estimator is an independent site operated by Ellul Solutions Ltd. It is not affiliated with, endorsed by or connected to the Illinois Department of Revenue, the New Jersey Division of Taxation, the New York State Department of Taxation and Finance or any government body, and it is not an accounting firm, a law firm or a tax adviser. Nothing here is tax advice on an individual move, and residency is decided on facts that this site cannot see. Every figure and every rule stated here is taken from published state guidance cited on this page and read on the date shown, and where the page says a state does not do something it means the guidance we read describes no such mechanism, not that we have searched the whole statute book. State rates and thresholds change on legislative cycles, so check the date at the top before relying on a figure.
