What is statutory residency in a US state?

A separate test, used by many states, that makes you a resident if you spend more than a threshold number of days (often 183 or 184) in the state and maintain a permanent place of abode there — even if your domicile is elsewhere.

What's the difference between domicile and statutory residency?

Domicile is where you intend your permanent home to be — a qualitative test evaluated over years. Statutory residency is a bright-line day-count-plus-abode test. A state can pull you in under either one.

Do I have to file in more than one state?

Often, yes. Part-year and nonresident returns are common after a move, and some states can claim you as a resident even while another treats you as a nonresident.

What is a permanent place of abode?

A dwelling in the state you have year-round access to — owned or rented, lived in or not. It's a factual test focused on availability, not how often the home is actually used.

US State Tax Residency

Two independent tests can pull you in — domicile and statutory residency. Either one can trigger state tax on worldwide income.

The answer

You can leave a state and still owe it tax.

US states run two parallel tests — domicile and statutory residency. Either one can keep the old state's claim alive, regardless of where you say you moved.

Why it matters

The cost rarely comes from the state you moved to.

It comes from the one you left.

Moving and leaving aren’t the same thing.

New York, California, Massachusetts — high-tax states don’t release you when you change your driver’s license. They watch for signals that you actually left. Days out of state. A home no longer available. Family no longer there. Income no longer tied.

When the signals don’t line up with the declaration, the old state keeps its claim.

You don’t change domicile by saying you moved.

One failed year is a six-figure problem for a mobile earner.

Two or three failed years compound.

Most people don’t lose on one mistake. They lose on the pattern.

You don’t find out during the year.

You find out later. When it’s expensive to fix.

How it works

Two tests. Either one can make you a resident.

Domicile. Your intended permanent home. Changing it takes actually leaving the old state and establishing the new one. Courts look at patterns, not declarations. Source: California FTB — Residency Status

Statutory residency. A bright-line test. Enough days in-state (often 183 or 184) plus a permanent place of abode, and you’re a resident — regardless of where you’re domiciled. Source: NY Department of Taxation and Finance — Income Tax Definitions

You can fail either test. Either one makes you a resident.

States run them differently. New York runs both — for the specifics, see our guide on New York statutory residency. California has no statutory day test but applies a closer-connection analysis that weights days heavily. Nine states have no broad-based income tax — but that only covers where you are. It doesn’t settle where you’ve been.

The record wins. Not the story.

If you think the state you left may still have a claim on you, run your situation through the Can My Old State Still Tax Me? tool — it weighs domicile signals, days in-state, and multi-year consistency.

Where people get this wrong

Thinking Florida or Texas ends it. The former state is usually what drives the risk. Changing where you pay tax doesn’t end where you owed it. The mechanics of actually executing that change are covered in our guide on moving to another state.

Relying on declarations. Voter registration, driver’s license, a forwarding address — these are inputs. They don’t settle the question.

Ignoring day count. Even in domicile-focused states, days in-state are evidence. The state you left counts them. The state you moved to counts them. Both sides are watching.

Leaving ties in place. A home still accessible. A spouse and kids still there. A job that keeps bringing you back. Each one is a signal the state weighs against the claim that you moved. A contemporaneous record of where you’ve been is what holds up in an audit.

Your move

Check your exposure

Most people don't realize where they're exposed until they check.
