You are an Oregon resident for income tax if either of two things is true: you are domiciled in Oregon, or you keep a permanent place of abode in the state and spend more than 200 days there during the tax year — the second route is the statutory residency test, and it does not apply if you prove you were in Oregon only for a temporary or transitory purpose. Keeping your in-state presence at 200 days or fewer avoids the day test, but not residency by domicile.

Who it applies to

This matters most if you are:

• A remote worker or frequent traveler spending long stretches in Oregon while based elsewhere.
• Someone who keeps a home or apartment in Oregon while living or working out of state.
• A snowbird or seasonal resident splitting the year between Oregon and another state.
• An individual moving to or from Oregon mid-year, where domicile and day count both come into play.

It applies regardless of citizenship — Oregon residency here is about domicile, physical presence, and having a home available, not visa or immigration status.

The rule — and why it exists

The definition comes from ORS Chapter 316, Oregon's personal income tax statute. It captures two separate groups of residents:

• Domicile. If Oregon is your true, fixed, permanent home — the place you intend to return to — you are a resident regardless of how many days you spend in the state.
• Permanent abode plus 200 days. If you maintain a permanent place of abode in Oregon and are physically present for more than 200 days in the tax year, you are a statutory resident even if you are domiciled somewhere else — unless you prove you are in the state only for a temporary or transitory purpose, such as a work assignment for a fixed and limited period.

Why it exists: states use domicile and a permanent home combined with sustained physical presence as proxies for where your economic life really sits. The two-pronged test stops people from claiming non-residency purely on day-counting while still keeping a genuine base in Oregon.

Counting the days

1. 1Count every day you are physically present in Oregon during the tax year (1 January to 31 December); by statute a fraction of a day counts as a whole day.
2. 2The count resets at the start of each new tax year — it is a per-year total, not a rolling 12-month window.
3. 3The day test only bites while you keep a permanent place of abode in Oregon; without that home, the 200-day count alone does not create statutory residency.
4. 4More than 200 in-state days plus that permanent abode makes you a resident; 200 or fewer keeps you outside this specific test.

A permanent place of abode means a dwelling you permanently maintain, owned or rented, kept long enough to create a well-settled physical connection with the area; a place kept only during a temporary stay of short duration for a particular purpose is not permanent. The 200-day threshold and the abode requirement must both be met in the same tax year for statutory residency to apply.

Examples

Example 1 — resident by days

You rent a house in Portland year-round and are physically present in Oregon for about 240 days, working remotely and traveling the rest of the time. You maintain a permanent abode and exceed 200 days, so you are a statutory resident and Oregon can tax your worldwide income for that year.

Example 2 — resident despite fewer days by domicile

Oregon is your home: your family, driver's licence, and voter registration are all there, and you intend to return. One year you travel for work and spend only ~150 days in-state. You remain an Oregon resident because you are still domiciled there — the day count does not save you.

Example 3 — under the threshold and not domiciled

You are domiciled in Nevada but keep a coastal condo in Oregon, staying about 180 days a year. Because you are not domiciled in Oregon and stay at or below 200 days, the statutory residency test is not met — though you may still owe Oregon tax on income sourced to the state.

Exceptions & edge cases

• Domiciliaries have only narrow exits. An Oregon domiciliary is taxed as a nonresident only under the 30-day safe harbor (no Oregon abode, a permanent home elsewhere, 30 days or fewer in Oregon), as a qualified individual under IRC § 911(d)(1) living abroad (or, in some cases, the spouse of one), or as an active-duty service member whose payroll residency is outside Oregon.
• Temporary assignments. Under the Department's rule, someone sent to work in Oregon for a fixed and limited period who takes an apartment is not a resident even past 200 days; an open-ended assignment is not temporary.
• Changing domicile is demanding. It requires actually abandoning Oregon as your home and establishing a new one elsewhere — traveling for part of the year is not enough.
• Source income still reaches non-residents. Even if you avoid statutory residency, Oregon can tax income earned from Oregon sources, such as wages for work performed in-state or Oregon rental property.
• Part-year moves. Moving into or out of Oregon mid-year can make you a part-year resident, taxed as a resident for the portion of the year Oregon was your home.

Common misconceptions

• "Under 200 days means I'm safe." False — if Oregon is your domicile, you are a resident with any number of days.
• "Only Oregon income is taxed." Statutory residency makes you a full-year resident taxed on worldwide income, not just Oregon-source income.
• "A hotel or short-term rental is a permanent abode." No — the abode must be a dwelling you permanently maintain, and a place kept only for a short temporary stay is not permanent.
• "Just leaving for the year ends my Oregon residency." Not on its own — you must genuinely abandon Oregon as your domicile and establish a new permanent home elsewhere.
