Oregon State Tax Rate Guide

Oregon State Tax Rate Guide – Oregon’s tax system stands out for its lack of a statewide sales tax, reliance on progressive income taxes, and unique business levies. This comprehensive Oregon State Tax Rate Guide breaks down current rates for individuals, businesses, property owners, and more. Whether you’re a resident, new to the state, or a business owner, understanding Oregon taxes helps with planning and compliance. All information is based on the latest data from the Oregon Department of Revenue (DOR) and trusted sources like the Tax Foundation as of 2026.

Oregon State Income Tax Rates and Brackets

Oregon imposes a graduated personal income tax on taxable income. Rates range from 4.75% to 9.9% for most taxpayers, with higher brackets for very high earners in recent updates. Taxable income starts from federal adjusted gross income with Oregon-specific additions and subtractions.

For tax year 2025 (returns filed in 2026), approximate brackets (adjusted annually for inflation; exact tables in DOR Form OR-40 instructions) are:

Single or Married Filing Separately:

  • 4.75% on $0 – ~$4,300
  • 6.75% on ~$4,301 – ~$10,750
  • 8.75% on ~$10,751 – $125,000
  • 9.9% on over $125,000

Married Filing Jointly or Qualifying Surviving Spouse (roughly double the single brackets):

  • 4.75% on $0 – ~$8,600
  • 6.75% on ~$8,601 – ~$21,500
  • 8.75% on ~$21,501 – $250,000
  • 9.9% on over $250,000

Head of Household: Brackets fall between single and joint.

For 2026 tax year, brackets receive minor inflation adjustments, and very high-income earners may face additional marginal rates (e.g., 10.9% and 11.9% in top tiers per some analyses), though the core structure remains progressive up to 9.9% for most. Use the official DOR tax calculator or rate charts for precision.

Oregon does not tax Social Security or Railroad Retirement benefits. Standard deductions and credits (e.g., retirement income credit, Oregon Kids Credit) can reduce liability. Full-year residents file Form OR-40; part-year/nonresidents use OR-40-P or OR-40-N.

No Sales Tax in Oregon: A Major Advantage

One of Oregon’s biggest tax benefits is zero state sales tax—and no local sales taxes either. This makes it one of only five states without a general sales tax. Purchases of goods and most services are tax-free at the register.

Exceptions include specific excise taxes on items like:

  • Alcohol
  • Tobacco
  • Fuel
  • Cannabis

This no-sales-tax environment benefits shoppers, tourists, and businesses but is offset by higher income and property taxes. Out-of-state sellers generally have no sales tax collection obligations in Oregon.

Oregon Property Tax Rates and How They Work

Oregon property taxes fund schools, local governments, and services. The statewide average effective rate is approximately 0.81%–0.90% of assessed value, though it varies significantly by county and taxing district.

Rates are applied to assessed value (capped under Measure 5/50 limits), not always full market value. In FY 2024–25, the average tax rate was about $9.18 per $1,000 of real market value statewide.

Highest-tax counties (effective rates often 1.0%+):

  • Multnomah County (Portland area)
  • Washington County
  • Clackamas County

Lower-tax rural counties include Wheeler, Grant, and Harney (often under 0.6%).

Property taxes appear on annual statements (due November 15 or in installments). Homeowners may qualify for exemptions or deferrals (e.g., senior citizens, disabled veterans). Always check your county assessor’s office for exact rates.

Corporate and Business Taxes in Oregon

Businesses face two main state-level taxes:

  1. Corporate Income/Excise Tax — Graduated rates:
    • 6.6% on taxable income up to $1 million
    • 7.6% on taxable income over $1 million
  2. Corporate Activity Tax (CAT) — A modified gross receipts tax:
    • $250 base tax + 0.57% on taxable Oregon commercial activity over $1 million
    • Applies to most entities (C corps, S corps, partnerships, LLCs, sole props) with over $1M in Oregon activity
    • Allows 35% subtraction for cost of goods/labor (with limits)

Oregon also has local business taxes in some areas (e.g., Portland Metro). Estimated payments and returns are required; consult Publication OR-CAT or a tax professional.

Other Oregon Taxes and Fees

  • Estate/Inheritance Tax — Oregon has an estate tax with a $1 million exemption (no inheritance tax).
  • Excise Taxes — On motor fuel, cigarettes, alcohol, and certain services.
  • Local Taxes — Portland’s $35 arts tax applies to many residents; some cities/counties have transient lodging taxes.
  • Unemployment Insurance and Workers’ Comp — Employer-paid payroll taxes (rates vary by industry/experience).

No state tax on retirement income from certain pensions, and Oregon offers several credits for low- to moderate-income families.

Filing Deadlines, Payments, and Requirements

  • Individual Returns — Due April 15, 2026 for 2025 tax year (or next business day).
  • Extensions — Available (federal extension often accepted).
  • Estimated Taxes — Required if you expect to owe $1,000+ after withholding/credits.
  • Payment Options — Online via Revenue Online, direct debit, or check.

Electronic filing is encouraged. Use the DOR’s free tax calculator for estimates.
