STATE RESIDENCY DAY COUNTER · RUNS IN YOUR BROWSER · NOTHING UPLOADED

How many days have I spent in each state, and am I near the 183-day line?

List where you were and when. The counter totals the days per state, checks them against the commonly published statutory residency tests, shows the room you have left and the date you would cross a limit, splits remote-work wages by workdays, and gives you a day-range record to keep.

An organising aid, not tax or legal advice: residency also turns on domicile and your ties, which a day count cannot settle. New to this? Read the 183-day rule by state, with a worked example, how the convenience-of-the-employer rule can tax remote days, how many days a Florida snowbird can spend in New York, why Maryland and Utah cap you at 182 days, the New York City resident test, why Georgia, New Mexico and Louisiana need no home to make you a resident, how Ohio's 212 contact-period safe harbor works, how the six-month tests in Nebraska, Colorado, Arkansas and Kansas work, the 200- and 270-day tests in Oregon, Hawaii and Idaho, or how California's nine-month presumption differs from a 183-day rule.

How it is calculated

Days: every date in the year is checked against your stays. A day counts for a state if any stay in that state covers it; the arrival and departure days both count unless you choose to count nights. Two states can share a travel day. Overlaps that are more than a travel day are flagged as a probable typo and counted in both.

Limits: the table of commonly published tests is: a permanent place of abode plus more than 183 days for New York, New Jersey, Connecticut, Massachusetts, Pennsylvania, Minnesota, Rhode Island, Virginia, Maryland and Utah (183 days or more), Michigan, Indiana, Kentucky, Vermont, Missouri, Iowa, Maine, West Virginia and Delaware, and the District of Columbia (183 days or more); 183 days or more with no home required for Georgia (counted over the trailing 365 days, which this tool approximates with the calendar year); 185 days or more with no home required for New Mexico; more than six months (taken as 183 days) with no home required for Louisiana; more than six months (taken as 183 days) with a home for Nebraska; more than 200 days for Oregon; more than seven months (taken as 210 days) with a home for North Dakota; more than 212 contact periods (approximated by nights) for Ohio; more than 270 days for Idaho; and for California a presumption of residency beyond about nine months. A statutory state is only marked over the limit when you say you keep a home there. You can type your own limit for any state. Rules change; check the state's current guidance.

Would cross on: the date you would pass the limit if you were in the state every day from the as-of date onward.

Workdays: Monday to Friday days, split evenly across the states worked on a shared day, as a share of all workdays; the wage figure applies that share to the wages you typed. Holidays and weekends worked are not modelled. Name your employer's state to see the convenience-of-the-employer view for the states commonly described as applying it (NY, NE, DE, AR; PA, NJ and CT against states that do the same).

Not modelled: domicile, where your family and belongings are, what counts as a permanent place of abode, part-year resident rules, reciprocity agreements, city taxes other than New York City's, foreign days, and state-specific ways of counting a day. The counts are checked against an independent recount in the test suite, but unverified against any tax authority's own determination.

Common questions

How many days can I spend in a state before I become a tax resident?

There is no single number. Several states, including New York, New Jersey, Connecticut, Massachusetts, Pennsylvania, Minnesota, Rhode Island, Virginia, Maryland and Utah (183 days or more), Michigan, Indiana, Kentucky, Vermont, Missouri, Iowa, Maine, West Virginia and Delaware, and the District of Columbia (183 days or more), publish a statutory test: you are treated as a resident if you keep a permanent place of abode there and spend more than 183 days in the state. Oregon uses 200 days, Ohio 212 contact periods (roughly nights), Idaho 270, and New Mexico counts 185 days or more of physical presence with no home required, and Louisiana more than six months (taken here as 183 days) with no home required, and Nebraska the same six months but only with a permanent place of abode. Many other states, California among them, decide residency by domicile and where your ties are strongest, so a day count alone does not settle it. The counter shows where you stand against the commonly published day tests and lets you enter your own limit.

Does the day I arrive or leave count?

Often yes. New York, for example, counts any part of a day spent in the state as a day. The counter defaults to that conservative reading and counts both the arrival day and the departure day. You can switch to counting nights, which drops the departure day, but check what your state says before relying on it.

What is a permanent place of abode?

Broadly, a home you keep and could use, whether you own or rent it, as opposed to a hotel stay or a short visit to relatives. Because the statutory tests usually need both the abode and the day count, the counter only flags a statutory state as over the limit when you tell it you keep a home there. Whether a particular dwelling counts is a question for the state's own guidance or a tax professional.

What if I am a resident of two states?

It happens, usually when one state treats you as domiciled there and another treats you as a statutory resident. The usual relief is a credit on the return of the state where you are a resident for tax paid to the other, which is why people who live partly in two states keep a day-by-day record. The counter produces that record and a CSV to keep.

How are my wages split between states when I work remotely while travelling?

Many states tax wages for work physically done in the state, and an employer's allocation often follows days worked. The counter estimates a share by counting Monday to Friday workdays in each state, splitting a shared travel day evenly, and applying it to the annual wages you type. It ignores holidays and your employer's own rules, and some states have a convenience-of-the-employer rule that can pull remote work back to the employer's state, so treat the figure as an estimate to discuss with a payroll or tax professional.

Can I use this to prove where I was to a tax authority?

It builds an organised record from dates you enter, which is a good start for the contemporaneous log auditors ask for, but it is not evidence by itself. Keep what supports the dates: travel receipts, card statements, calendar entries and phone or toll records. Nothing you type is stored or uploaded, so download the CSV and keep your own copy.

Is my travel history uploaded anywhere?

No. Everything is calculated in your browser from what you type, nothing is sent to a server, there are no accounts, and it works offline once the page has loaded.
