Oregon (OR) Paycheck Calculator

Oregon has four income tax brackets for 2026. For single filers: 4.75% on income up to $4,550, 6.75% from $4,550 to $11,400, 8.75% from $11,400 to $125,000, and 9.9% above $125,000. Married filing jointly filers use wider thresholds: 4.75% up to $9,100, 6.75% from $9,100 to $22,800, 8.75% from $22,800 to $250,000, and 9.9% above $250,000. The thresholds are inflation-adjusted annually by the Oregon Department of Revenue. Source: oregon.gov/dor.

The Oregon standard deduction for 2026 is $2,910 for single filers and $5,820 for married filing jointly. These amounts are inflation-adjusted annually. Oregon does not have a separate head of household filing status — federal HOH filers use the single brackets and standard deduction in Oregon.

No. Oregon does not recognize head of household as a separate state filing status. Oregon uses four filing statuses: single, married filing jointly, married filing separately, and qualifying surviving spouse. Federal head of household filers file as single for Oregon income tax purposes, using the single bracket schedule and the $2,910 standard deduction.

Yes. Portland Metro area residents pay a 1% Supportive Housing Services (SHS) tax on Oregon taxable income above $125,000 (single) / $200,000 (joint). Multnomah County residents also pay the Preschool for All (PFA) tax: 1.5% on Oregon taxable income above $125,000 (single) / $200,000 (joint), rising to 3% above $250,000 (single) / $400,000 (joint). These local taxes are not included in this calculator. If you live or work in the Portland metro area, your actual tax burden will be higher.

Yes. Oregon taxes Oregon taxable income, which starts from federal AGI. Pre-tax 401(k) contributions reduce federal AGI and therefore Oregon taxable income. On an $80,000 salary, a 6% 401(k) contribution saves approximately $421 in Oregon income tax ($4,800 × 8.75% marginal rate for that income range).

This calculator uses the IRS Publication 15-T percentage method (annualized wages, post-2020 W-4). Your annual salary is reduced by any pre-tax deductions you enter, then by the federal standard deduction for your filing status. The resulting federal taxable income is run through the 2026 federal income tax brackets to get the annual withholding, which is divided by your pay periods.

Social Security is 6.2% of your gross wages up to the 2026 wage base of $184,500. Medicare is 1.45% of all wages with no cap. High earners (above $200,000 for single filers, $250,000 for married filing jointly) also owe an Additional Medicare surtax of 0.9% on wages above that threshold. These are the employee shares; your employer pays a matching amount separately.

Yes. Traditional 401(k) contributions reduce your federal taxable income (and therefore your federal income tax withholding). They also reduce the tax base in most states, including Oregon. Roth 401(k) contributions are post-tax and do not reduce current-year tax.

This calculator covers federal income tax, FICA (Social Security + Medicare), and Oregon state income tax. It does not include: Excludes Portland Metro Supportive Housing Services Tax (1% on Oregon taxable income above $125,000 single / $200,000 joint for Portland Metro area residents) and Multnomah County Preschool for All tax (1.5%–3% above $125,000 for Multnomah County residents). Oregon has no SDI. Oregon Statewide Transit Tax (0.1%) is a payroll tax, not an income tax, and is excluded. It is an estimate for budgeting purposes — your employer's actual payroll system and your W-4 elections determine your exact withholding.

Your marginal tax rate is the rate that applies to your last dollar of income (the highest bracket you fall into). Your effective tax rate is your total taxes divided by your gross salary — it is always lower than your marginal rate because lower income is taxed at lower bracket rates. The effective rate shown here includes federal income tax, FICA, and state income tax.
