Ohio bright-line non-residency caps your time in Ohio at 212 days per calendar year. The statute attaches its consequence at 213 days or more, so 212 is the last safe count. Ohio counts **contact periods**, not days: a contact period is an overnight stay away from your abode outside Ohio. This counter approximates them with calendar days, which is conservative — it can only ever overstate your exposure, never hide it.
Who it applies to
This matters most if you are:
- A remote worker, digital nomad or frequent traveller spending long stretches in Ohio.
- An expat arriving in or leaving Ohio mid-year, where the days straddle a boundary.
- Anyone keeping a home in more than one country who needs a defensible day count for a tax return.
The rule — and why it exists
Contact periods in Ohio. At most 212 days in Ohio per calendar year — <=212 / YEAR. It also requires: Did you keep a permanent home outside this state for the whole year?.
Why it exists: countries use time spent as a measurable proxy for where your economic life really is. A day count gives a clear threshold; the surrounding tests stop a long holiday from making a genuine non-resident taxable.
Counting the days
- Add up every day you were physically in Ohio between 1 January and 31 December.
- Days need not be continuous — several visits in the same year add together.
- Any day of presence generally counts, including arrival and departure days.
- The tally resets to zero on 1 January; it is not a rolling window. Reaching 213 days meets the threshold.
- The count alone does not decide this rule. It also depends on: Did you keep a permanent home outside this state for the whole year?.

Examples
Example 1 — 127 days in the year
Stays: United States (OH) 2026-02-01 → 2026-06-07. Checked on 2026-12-31.
Result: Contact periods in Ohio: 85 of 212 days left (127 used in Ohio).
Example 2 — 222 days in the year
Stays: United States (OH) 2026-01-15 → 2026-08-24. Checked on 2026-12-31.
Result: Contact periods in Ohio: over the limit — 222 of 212 days, first exceeded 2026-08-15.
Example 3 — Days split across two calendar years
Stays: United States (OH) 2025-10-01 → 2025-12-31; United States (OH) 2026-01-01 → 2026-05-07. Checked on 2026-12-31.
Result: Contact periods in Ohio: 85 of 212 days left (127 used in Ohio).
Exceptions & edge cases
- Other residency tests. Most countries also apply a domicile, home or centre-of-interests test; you can be resident under one of those with fewer days.
- Double-tax agreements. If two countries both claim you, the treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) decides.
- Split years. Arriving or leaving mid-year may be treated under special rules; the day count is only one input.
Common misconceptions
- "Under 212 days means I'm safe." False — other tests can apply, and the count is only one input.
- "It follows a rolling year." No — the tally resets on 1 January.
- "Arrival day doesn't count." Any part of a day inside is a day inside.
