What changed for 2026
The 2026 tax year brings the usual annual inflation adjustments, a higher Social Security wage base, and one Oregon-specific note about the kicker. Oregon’s four income-tax rates and its unique federal tax subtraction are unchanged.
Oregon: rates unchanged, subtraction intact
Oregon’s income tax remains the four-bracket system: 4.75%, 6.75%, 8.75% and 9.9% above about $125,000 of base wage for single filers ($250,000 married). The federal tax subtraction — Oregon lets you subtract up to $8,750 of federal tax withheld before computing state tax — is unchanged, as are the $2,910 single / $5,820 married standard deductions and the $263-per-allowance credit.
Federal standard deduction 2026
The federal standard deduction rises to $16,100 for single filers, $32,200 for married couples filing jointly, and $24,150 for heads of household for 2026. Because it is subtracted before federal tax is computed, the higher deduction means slightly more of every Oregon paycheck stays with you compared with 2025.
Federal brackets 2026
The 2026 federal brackets were adjusted for inflation. For single filers: 10% up to $12,400; 12% to $50,400; 22% to $105,700; 24% to $201,775; 32% to $256,225; 35% to $640,600; and 37% above. The bracket widths are wider than 2025, which holds more of your income in the lower rates.
Social Security wage base rises to $184,500
The Social Security wage base — the earnings ceiling for the 6.2% Social Security payroll tax — rises to $184,500 for 2026. The 1.45% Medicare tax has no cap, and the extra 0.9% Medicare surtax still applies above $200,000 for single filers ($250,000 married).
Paid Leave Oregon cap set at $184,500
Paid Leave Oregon’s employee premium is 0.6% of wages, capped at $184,500 for 2026 — so the most you contribute is $1,107 a year. The Statewide Transit Tax (0.1%, no cap) is unchanged.
Portland local taxes: no changes
The Metro Supportive Housing Services tax remains 1% on wages above $125,000 single / $250,000 married, capped at $250,000 of wages. The Multnomah County PFA remains 1.5% above $125,000 and 3% above $250,000, with no cap. Below $125,000, Portland-area workers pay no local income tax.
The kicker
Oregon’s kicker refunds surplus income tax when revenue beats the forecast by 2% or more. The 2025 tax year (refunded in 2026) triggered a kicker of roughly 9.1% of Oregon tax paid. The 2026 outcome depends on revenue through the end of the year.
How the calculator tracks the changes
All of the numbers above live in a single data file that the calculation engine reads. When any figure changes — a wage base, a local rate, a kicker — the data file is updated and every page of the site recalculates automatically. This page is the changelog for that process.
