Oregon State Income Tax Guide (2026)

Oregon's 9.9% top rate is among the highest in the country, kicking in at just $125,000 of single taxable income ($250,000 MFJ) — dramatically earlier than CA (13.3% at $1M+), NY (10.9% at $25M+), or NJ (10.75% at $1M+). The 8.75% bracket from $10,750 to $125,000 is what most working professionals actually pay. A $100K single OR earner faces an effective state rate around 7.5% — among the highest 'middle-class' effective rates in the country.

The structural feature that softens this is Oregon's federal tax liability subtraction. OR is one of only 5 remaining states (with AL, LA, MO, MT) that allow subtracting federal income tax paid from state taxable income. The 2026 cap is approximately $8,500, with linear phase-out: full cap up to federal AGI $145K single / $290K MFJ, fully phased out at $215K / $430K. A $100K single filer captures the full $8,500 — saving about $745 in OR state tax annually. At $200K single (mid phase-out), the benefit drops to roughly $3,000-$4,000. Above the phase-out, zero.

Portland's local surtaxes are the part most relocators don't see coming. The Multnomah County Preschool For All Tax (PFA) adds 1.5% on single filer income $125K-$250K and 3% above $250K (MFJ thresholds are higher). The Metro Supportive Housing Services Tax (SHS) adds 1% on income above $125K single / $200K MFJ in the tri-county Portland metro area (Multnomah, Washington, Clackamas counties). For a Portland resident at $300K of taxable income, the stack is roughly 9.9% state + 1.5% PFA + 1% SHS = 12.4% combined marginal. At $500K: 9.9% + 3% + 1% = 13.9%. These are real, separately-administered local taxes — not part of the OR state return.

Standard deduction is unusually low ($2,420 single / $4,840 MFJ for 2026) — well below the federal $16,100 / $32,200. OR taxable income tracks much closer to gross than federal taxable income, so more income falls into higher brackets than in federal-conforming SD states.

Tens of thousands of Portland-region workers live in Vancouver WA and commute across the Columbia River via the I-5 or I-205 bridges. The tax mechanics are the structural reason Vancouver's population has grown faster than Portland's for over a decade. WA has no state income tax. OR taxes WA residents only on wages earned for work physically performed in Oregon (PDX-source income), filed via Form OR-40-N (non-resident). Days physically worked in WA — remote from a Vancouver home, or at a WA-side office — are NOT OR-source income and escape OR tax entirely.

The Portland local surtaxes (PFA, SHS) do NOT apply to non-residents. So a Vancouver-based Portland tech worker pays only OR state tax on PDX-source workdays, with no Multnomah County or Metro surtax exposure. For a hybrid worker living in Vancouver who splits 60/40 between a downtown Portland office and home: only 60% of wages are OR-source and subject to OR's 8.75-9.9% rate. The other 40% is exempt from state-level income tax entirely. At $150K of comp with a 60/40 split, that's roughly $90K subject to OR state vs $60K subject to nothing — saving ~$5,000/year of OR tax plus avoiding $1,400/year of Portland surtaxes for a full-time PDX-resident peer.

The trade-offs versus full Portland residency are real but smaller than the tax savings for most professionals: Vancouver schools are competitive but not Portland-public-school-grade in the strongest districts; the commute adds 25-40 minutes each way depending on bridge traffic; and Vancouver's downtown is noticeably thinner than Portland's. But the math has worked for over a decade and continues to attract Portland-region tech, healthcare, and corporate workers. The cross-border setup is the genuine reason a meaningful share of Portland-region professionals quietly live across the river.

Reverse case: OR residents working in WA pay OR tax on all income regardless of where earned (no WA tax to credit against). A Portland resident commuting to Amazon Seattle or Microsoft Redmond pays OR's full 8.75-9.9% on the wages plus any Portland surtaxes — same comp earned by a Vancouver WA resident: $0 state-level tax.

Four scenarios that cover most readers. Find the one closest to you. If none match, the calculator at the top is for you.

Oregon property tax statewide effective average is about 0.93% on market value — moderate by national standards. The structural feature is Measure 50, passed by voters in 1997, which caps annual assessed value growth at the lower of 3% or actual market change. Long-tenured Oregon homeowners often pay property tax on an assessed value far below current market — a Prop 13-style benefit that compounds over decades of homeownership.

Approximate effective rates by county on a primary residence: Multnomah (Portland) 1.0-1.4%, Washington County (Hillsboro/Beaverton/Tigard) 0.95-1.20%, Clackamas (Lake Oswego/West Linn/Oregon City) 0.90-1.15%, Lane (Eugene) 0.95-1.20%, Marion (Salem) 1.05-1.30%, Deschutes (Bend) 0.65-0.85%, Jackson (Medford/Ashland) 0.90-1.10%.

Measure 50 produces notable intra-neighborhood variability between long-tenured owners and recent buyers. A Portland homeowner who bought in 2002 may pay property tax on a $250K assessed value against $850K market — effective rate ~0.4% of market. The same house bought today would assess near market and pay roughly $9,500-$10,500/year — about 2.5x the long-tenured owner's bill on identical property. The OBBBA SALT cap raise to $25K softens the deductibility hit but doesn't change the cash bill.

If you're earning $100K+ in OR and you're not doing most of these, you may be leaving real money on the table. None of this is exotic. Most of it is 30 minutes of setup once a year and discipline the rest of the year.

Oregon is appreciably high-tax for working professionals, especially Portland metro residents. The combination of a 9.9% top state rate kicking in at just $125K single, plus 1-3% Portland local surtaxes for tri-county residents, plus a $1M estate tax exemption among the lowest in the country, makes OR one of the more financially expensive places to be a high-earning professional. The offsets are genuine: no state sales tax, the federal tax liability subtraction softens effective rates for filers under the phase-out, Measure 50 caps property tax assessment growth for long-tenured homeowners, and the Pacific Northwest outdoor lifestyle is real lifestyle-economy value that doesn't show up on a tax line.

Run your numbers in the calculator above. The OR state line includes the federal tax liability subtraction with the phase-out math, so it should track closely with your actual OR-40 return.

If you're a Portland tri-county resident, add the PFA and SHS surtaxes manually — they're filed separately from OR state and the calculator doesn't model them. If you're considering Vancouver WA living plus Portland working, model the WA-OR commuter math honestly: PDX-office days are OR-source, WA-side remote days are not.

If you're 62 or older with retirement income, verify the Oregon Retirement Income Credit is being applied. The biggest tax mistake most Oregonians make isn't paying too much state income tax — it's not factoring Portland metro surtaxes when moving to Portland from a low-tax state, or missing the federal tax subtraction phase-out math on the OR-40 return.
