Basis

ORS Chapter 316

Oregon treats you as a statutory 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. Meeting either test makes you a full-year resident taxed on your worldwide income. Keeping your in-state presence at 200 days or fewer avoids the day test — but only while you are not otherwise domiciled in Oregon.

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.

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).
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 maintain that is suitable for year-round living — an owned or rented home, not a hotel stay or a short holiday let. 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

• Domicile overrides the day count. An Oregon-domiciled person can only avoid resident treatment in narrow statutory situations, not merely by staying under 200 days.
• 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 maintain and that is suitable for year-round living.
• "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.
