State residency day counter

Pick a state and enter your days. The counter shows how many days remain before the common 183-day statutory-residency line, or tells you when a state has no income tax or uses a facts-and-circumstances test instead. Everything runs in your browser.

How the day count decides residency

Most income-tax states can tax you as a statutory resident if you keep a permanent place of abode there and spend more than 183 days in the year (184+). Two groups are different:

For a mover, the harder job is usually proving you stayed under the old state's line — which is exactly what a contemporaneous day record is for.

Frequently asked questions

Updated 2026-09-13

How many days can I spend in a state without becoming a resident?
In most income-tax states, statutory residency triggers when you spend more than 183 days there while maintaining a permanent place of abode, so 183 is the last safe day. A few states use different day counts, and some, like California, use a facts-and-circumstances test with no bright line.
Does a partial day count as a day?
In New York and several other states, yes: any part of a day counts as a full day, with narrow exceptions such as travel in transit. Arriving late in the evening still burns a day.
Which states have no income-tax day test?
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming levy no broad-based income tax, so there is no day threshold to become taxable there. The counting problem is staying under the threshold of the state you are leaving.
What if I split the year across three or more states?
Each state applies its own test independently, so you can be over a line in one while safe in the others. The count that matters is per state, which is exactly why a per-state automatic ledger beats a single calendar.

Not tax advice. Thresholds shown are the common 183-day statutory test; each state's exact rule, and the definition of a "day," can differ. Confirm your situation with a qualified advisor.
