What Oregon residents actually pay
Oregon taxes ordinary income at a top marginal rate of 9.9%. RSU settlement value, NSO exercise spread, and ESPP discount income all count as ordinary wages for this purpose and flow through the state's normal brackets.
High top bracket; Portland has meaningful tech presence.
Withholding gap
Federal supplemental-wage withholding on RSU vesting is flat — 22%, rising to 37% once year-to-date supplemental wages exceed $1M. If your actual marginal rate is higher, the shortfall shows up at filing. In Oregon, layer on 9.9% at the top and model what you'll owe before year-end.
Sourcing when you move
If you earned part of a vesting tranche while in a different state, most high-tax states (California, New York, Massachusetts) use workday allocation between grant and vest. Your payroll will likely withhold only for your current state, so a manual true-up at filing is the rule, not the exception.
Frequently asked
- Does Oregon tax RSU income the same as wages?
- Yes. Oregon treats RSU ordinary income as wages, taxable at the state's top marginal rate of 9.9%. Supplemental-wage federal withholding (22%, or 37% above $1M YTD) does not adjust for state withholding, so you often owe extra at filing.
- What happens if I exercise ISOs while living in Oregon?
- Oregon does not run a separate state AMT, so only federal AMT applies. You still need to model the bargain element carefully if you plan a cashless exercise-and-sell.
- I moved to Oregon from another state. Who taxes my vesting RSUs?
- Most high-tax states (CA, NY, MA) source RSU ordinary income to workdays between grant and vest. If your grant pre-dates your Oregon move, expect the old state to tax the portion of each tranche attributable to workdays earned there. Oregon taxes the remainder.
- Can I reduce Oregon taxes by timing my RSU sales?
- Oregon taxes long-term capital gains at the same rate as ordinary income, so timing alone does not produce a state savings — only federal. Holding for 12 months still halves the federal rate on gains above basis.
