State Tax Residency Rules for Remote Workers Who Moved in the Last Year

Remote work untethered a lot of people from the assumption that where you live and where you're taxed are the same simple fact. States don't determine residency based on a single event like a change-of-address form — they look at a bundle of factors, and if a filer moves mid-year without deliberately severing ties to the old state, both the old and new state can each have a legitimate claim to tax at least part of that year's income.

What states actually look at

Residency (often called "domicile" in tax terminology, meaning the place someone treats as their true, permanent home) is generally established through a combination of factors, no single one of which is decisive on its own:

• Physical presence — many states use a rule-of-thumb threshold around 183 days in the state during the year as a trigger for residency, though the exact rules and definitions vary by state.
• Voter registration — remaining registered to vote in the old state after moving is a common piece of evidence used against a residency change.
• Driver's license and vehicle registration — an old-state license kept "just in case" is one of the most common self-inflicted residency problems.
• Where a primary home is owned or leased, and whether the old home was sold, rented out, or kept as a vacant second residence.
• Where banking, healthcare providers, and professional licenses are based.

A move is far cleaner, from a tax-residency standpoint, when most or all of these factors point the same direction on the same date, rather than trickling over weeks or months.

The "convenience of the employer" trap

A handful of states apply what's known as a "convenience of the employer" rule: if a remote employee works for a company based in one of these states, but works remotely from a different state purely for their own convenience rather than because the employer required it, the employer's state can still tax that income as if the work were performed there. This rule specifically catches remote workers who moved away from an employer's home state but kept the same job — someone can genuinely, fully relocate to a new state and still owe tax to their employer's state on the same income, depending on how that state's rule is written and whether any exception applies.

Moving your home is a fact about where you sleep. Moving your tax residency is a fact about paperwork — and the two don't automatically happen on the same day.

An illustrative example of how dual taxation happens

Picture a remote worker who moves from State A to State B on July 1, immediately buying a home in State B and updating their address with their employer. But they keep their State A driver's license because renewing feels like a hassle, stay registered to vote in State A through the November election "since I'm already registered," and don't formally establish domicile paperwork in State B until the following January. State A's tax authority, reviewing the return, sees a driver's license, a voter registration, and no clear severance date, and treats the worker as a State A resident for the full year, taxing all twelve months of income. State B, where the worker actually lived and worked for the second half of the year, also asserts residency starting July 1. Without a tax credit or reciprocity agreement resolving the overlap (which some but not all state pairs have), the worker can end up filing part-year returns in both states and, in a worst case, facing a dispute over which state's claim is stronger for the overlapping period — an entirely avoidable situation caused by loose ends left in the old state.

What a clean move actually requires

Severing residency cleanly generally means, on or near the actual move date: updating the driver's license and vehicle registration to the new state, re-registering to vote in the new state (and formally canceling the old registration, not just letting it lapse), notifying banks, healthcare providers, and any professional licensing boards of the new address, and — if keeping the old home — either selling it or converting it clearly to a rental rather than leaving it available as a residence to return to. The clearer and more concentrated in time these changes are, the harder it is for the old state to reasonably argue residency continued past the move date.
