Moving to Another State

How this engine works

You enter your own figures; the engine models two scenarios side by side and shows the twelve-month difference between them. The outputs are estimates built from your inputs and documented assumptions — not predictions, and not advice. Mood and stress are self-reported context that adjust the wording of the summary, nothing else. Inputs are processed in your browser. The full methodology, including what the engine does not claim, is on the Decision Center.

Step 2: Decision Forge — compare assumptions

Decision scenarios with reflection prompts

Each scenario in the tool above presents two options drawn from this event and models them side by side from the figures you entered. Before the comparison, the page names a cognitive-bias concept as an educational reflection prompt. It is a general prompt attached to the scenario rather than a finding about you: the page does not test whether the concept applies to your situation, and it does not indicate which option you should choose.

Self-reported context at decision time

The page does not create a psychological profile. Mood and stress may tailor wording and general next-step suggestions. They do not change the entered financial values or scenario math. They do not establish decision readiness. The named bias concept is a general reflection prompt; the page does not detect bias, assess decision capacity, diagnose a condition, or predict outcomes.

The day counts that decide which state taxes you

A move is taxed by the calendar and by the state, and the two largest states do not count the same way. Three of these four are counted in days or in years. The fourth is a door that has now been shut permanently.

The moving expense deduction did not come back

It was suspended in 2017 and a great many pages have been predicting its return ever since. The suspension is now permanent — 2025 legislation struck the expiry date rather than extending it.

Two groups can still deduct: active-duty military moving under orders, and, newly from tax year 2026, certain intelligence community employees moving under a required change of assignment. Everyone else cannot, and there is no version of the deduction waiting to be restored.

The same rule governs employer help, and this is the expensive half. Relocation assistance from an employer is taxable wages — it appears in your W-2 income and is subject to withholding and payroll tax. The form of the payment does not change that: a lump sum, a direct-billed van line and a third-party relocation company all produce the same result. A $20,000 relocation package is not $20,000 of moving budget, and the gap is the thing to negotiate about.

Which state can tax you, and why the day count is not the whole test

Two independent hooks decide this, and people usually know only one of them.

Domicile is the place you intend as your permanent home and return to. You have exactly one, it does not change because you spent a year elsewhere, and the burden of proving you changed it falls on whoever asserts the change — typically you, by clear and convincing evidence. Statutory residency is the other hook: maintaining a permanent place of abode in the state plus spending enough days there.

The familiar “183-day rule” is both slightly wrong and materially incomplete. In New York, which is the most litigated example, the threshold is 184 days or more — more than 183, not 183 — and it applies only where a permanent place of abode was maintained for substantially all of the year. A day count on its own never makes you a resident without an abode, and it never un-makes domicile.

What states weigh when domicile is in dispute is concrete: where your home is, where your active business involvement is, where you spend time, where the items near and dear to you are kept, and where your family connections are. Moving a driving licence and a voter registration is the easy part; moving the items you would grab in a fire is the part that convinces an auditor.

The nine states with no individual income tax

Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. Three of them carry caveats that have changed recently.

• New Hampshire taxed interest and dividends until recently; that tax was repealed for tax periods beginning on or after 1 January 2025. Pages listing it as taxing investment income are out of date.
• Tennessee’s equivalent was fully repealed in 2021.
• Washington has no income tax but does impose a capital gains excise tax — 7 percent above a roughly $1 million standard deduction, plus an additional 2.9 percent on gains above $1 million, which is new from tax year 2025. A page quoting a flat 7 percent is describing the old structure.

And the general caution: no income tax does not mean low taxes. The revenue is raised somewhere — usually property or sales tax — and for a given household the total can go either way.

Mail and movers

A change of address costs $1.25 online, charged purely to verify your identity against the card you use, and it is free in person at a post office with identification. Third-party sites that appear above the official one in search results charge up to forty dollars for the same filing, and some take the money without filing anything.

Standard forwarding runs twelve months and is extendable, but it does not treat all mail alike: first-class is forwarded free, periodicals for only 60 days, package services for twelve months with postage due from you, and advertising mail generally not at all. Plan to change the address directly with anyone who matters rather than relying on forwarding to carry you.

For an interstate move, federal rules require the mover to give you the booklet “Your Rights and Responsibilities When You Move” along with the written estimate, and to offer two levels of liability.

Neither of these is insurance, and neither is described as insurance in the rules. Verify any interstate mover’s registration in the federal database before paying a deposit — that single check eliminates most of the rogue operators.

Moving to the United States

Three administrative facts do more work than anything else in the first year.

Tax residency is a formula, not a status. The substantial presence test counts you as a US tax resident if you are here at least 31 days this year and at least 183 days across three years, counting all of this year’s days, a third of last year’s and a sixth of the year before. Certain visa categories are exempt from counting days at all but must file a form to claim it.

An individual taxpayer identification number is only for people ineligible for a Social Security number. You cannot hold both, it does not authorise work or confer any immigration status, and it exists purely so that tax can be filed. Allow several weeks, longer during filing season.

Foreign accounts have their own filing. If the combined value of your accounts outside the US exceeded $10,000 at any point in the year, a separate report is required — filed electronically, not with your tax return, due in April with an automatic extension to October. It applies to the aggregate, so several small accounts can trigger it where no single one would.

One thing to expect rather than be surprised by: a credit history does not cross borders. However long and excellent your record elsewhere, US lenders will see nothing, and you will start effectively invisible. Secured cards and becoming an authorised user are the usual ways in, and it takes months rather than weeks.
