The rule in one paragraph
As a Washington resident you are a non-resident of Oregon. Oregon may tax your Oregon-source income and nothing else. For wages, Oregon-source means work physically performed inside Oregon. You report it on Form OR-40-N, the Oregon non-resident return, which calculates tax on the Oregon portion of your income while taking your total income into account for rate purposes.
What Oregon can and cannot reach
| Income | Taxable by Oregon? | Why |
|---|---|---|
| Wages for days worked at a Portland office | Yes | Services physically performed in Oregon |
| Wages for days worked at home in Vancouver | No | Services performed outside Oregon |
| Your spouse’s wages from a Washington employer, work done in WA | No | No Oregon source |
| Interest and dividends | No | Intangible income follows residency |
| Gain on selling your Vancouver house | No | Washington real property |
| Rent from a rental house in Gresham | Yes | Oregon real property |
| Self-employment income from work done in Portland | Yes | Oregon-source business activity |
The part most people get wrong
Payroll systems are usually set up once and left alone. If your employer registered you as an Oregon employee in 2019 when you were in the office five days a week, and you now go in twice a week, the withholding almost certainly has not changed — but the correct Oregon-taxable share of your wages has dropped by 60%.
Metro SHS and Preschool for All — the surprise second layer
Washington residents are often told they owe "no Oregon tax", which is wrong in a specific and expensive way. The Metro Supportive Housing Services tax and the Multnomah County Preschool for All tax apply to income sourced to those jurisdictions, which includes wages earned by a non-resident working there. If your Oregon-sourced income exceeds the threshold, you have a local return to file even though you have never lived in Oregon.
- Metro SHS: 1% on Oregon-district-sourced income above $128,000 single / $205,000 joint (2026)
- Multnomah PFA: tiered from 1.5% above $125,000 single / $200,000 joint
- A Portland office inside Multnomah County means both may apply; an office in Beaverton means Metro only; an office in Vancouver means neither
What to do about it
- 1Start a workday calendar today. Even mid-year, a contemporaneous record from here forward is better than nothing at all.
- 2Check what your employer is withholding against how you actually work now.
- 3Ask payroll to correct the allocation where the pattern has changed. Many employers will; some will not, and that is survivable because the return fixes it.
- 4File OR-40-N reporting the Oregon-source portion, claiming the remaining withholding.
- 5Check the prior open years. Three years is the general window, so more than one may still be claimable.
- 6Check the local returns — Metro SHS and PFA, if your Oregon-sourced income clears the thresholds.
Will my employer get in trouble if I claim this back?
No. The employer withheld and remitted correctly to Oregon; the return simply reconciles what Oregon was actually owed against what was paid. This is what non-resident returns are for.
Does it matter that my paycheque comes from an Oregon bank account?
No. Nor does where the company is headquartered, where the payroll processor sits, or where your manager lives. Where you were physically working is the test.
What if I cannot prove my workdays?
Badge records, VPN logs, calendar entries, expense reports and parking receipts all help. Start with what your employer already logs — it is usually more than you think.
Do I still get an Oregon standard deduction?
Non-residents get a prorated benefit through the way OR-40-N calculates tax on the Oregon-source share. It is not the same as a full resident deduction, but it is not nothing.
I also have a side business at home in Vancouver. Is that Oregon income?
Generally not, if the work is performed at your Washington home for clients wherever they are. But if you perform services on-site in Oregon for clients, that portion is Oregon-source.
Get the sourcing right before you file
Cross-border returns turn on facts nobody asks you about until it is too late. An appointment settles which state taxes what.
