Oregon Paycheck Calculator (2026 Take-Home Pay)

Someone moving to Oregon for a job and building a budget around the offer letter number should know one thing up front: Oregon's income tax runs on a graduated schedule that climbs to a 9.90% top marginal rate across four brackets, among the higher state tax burdens in the country. This calculator applies verified 2026 figures to walk through the entire withholding chain, including federal income tax, FICA payroll taxes, and Oregon's own state tax, then prorates the result across bi-weekly, semi-monthly, monthly, or weekly pay periods. Pre-tax elections matter here too: a 401(k) or HSA contribution reduces the wages used to calculate federal and state tax, even though FICA still applies to the full gross amount, so the order those deductions happen in changes the final number. Salaried employees weighing an offer, hourly workers tracking a raise, and the payroll administrators who process their pay all rely on the same math, just pointed at different figures. Given how much of a paycheck the state tax portion can represent here, an exact calculation matters more in Oregon than it would in a state with a lower or flatter tax structure.

Oregon takes the largest bite of any state in this set. The bottom bracket is 4.75%, the 8.75% rate arrives at $11,400 of taxable income, and the top rate is 9.9% above $125,000. Oregon has no sales tax, which is the trade the state made, and Oregon employees also contribute to the state paid leave program through a separate payroll deduction. The income tax piece works out to:

Four steps stand between gross salary and net pay:

1. FICA Payroll Tax Computation: - Social Security (OASDI): 6.20% withheld on wages up to the 2026 statutory wage base ($184,500). - Medicare (HI): 1.45% withheld on all gross earnings (no wage cap), plus 0.90% Additional Medicare Tax on earnings exceeding $200,000 (single) or $250,000 (married filing jointly).
2. Federal Income Tax Withholding: Evaluated using 2026 progressive federal tax brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) after applying standard deduction thresholds ($16,100 single / $32,200 married joint).
3. Oregon State Income Tax Withholding: Run against the 2026 Oregon schedule (4.75%, 6.75% above $4,550, 8.75% above $11,400, 9.9% above $125,000).
4. Pay Period Proration: Annual net compensation is divided across the designated pay frequency (26 bi-weekly, 24 semi-monthly, 12 monthly, or 52 weekly pay periods).

Consider an employee in Oregon earning $75,000 annually, paid bi-weekly (26 paychecks per year), filing single, with $3,500 in annual pre-tax 401(k) contributions.

1. Gross pay per paycheck. $75,000 ÷ 26 pay periods = $2,884.62 before any withholding.
2. Pre-tax deduction. The $3,500 annual 401(k) contribution reduces each paycheck by $134.62 and also shrinks the wages used to calculate federal and state income tax; FICA is still assessed on the full gross amount.
3. FICA payroll taxes. Social Security withholds 6.2% of gross pay ($178.85) and Medicare withholds 1.45% ($41.83), for $220.67 per paycheck.
4. Federal income tax withholding. Applying the 2026 IRS withholding tables to the reduced taxable wage withholds $265.38 per paycheck.
5. Oregon state tax withholding. Oregon's withholding tables apply to the reduced taxable wage, withholding $228.36 per paycheck.
6. Net take-home pay. $2,884.62 gross, minus $134.62 pre-tax, minus $220.67 FICA, minus $265.38 federal tax, minus $228.36 state tax leaves $2,035.59 per paycheck, or $52,925.25 per year, an effective total tax rate of 24.77%.

Two Months In, And Then The Whole Year

Oregon has no sales tax and pays for it here: a 4.75% entry rate rising to 8.75% above $11,400 produces the heaviest state cumulative line of any page in this family.

Step 7 -- Two months of cumulative pay. The schedule's first row shows $6,250.00 of cumulative gross against $4,410.44 of cumulative take-home. Row two doubles both: $12,500.00 gross, $8,820.88 take-home, with $3,679.13 accumulated on the deduction side.

Step 8 -- The full year. By month twelve the schedule reaches $75,000.00 of cumulative gross and $52,925.25 of cumulative take-home, adding $4,410.44 every month without variation.

Step 9 -- What the year actually withheld. The cumulative deduction column closes at $22,074.75. That column carries the $3,500 pre-tax 401(k) contribution alongside the tax, so tax alone is $22,074.75 - $3,500 = $18,574.75, an effective total tax rate of 24.77% on $75,000.00 of gross pay.

Step 10 -- Why the monthly increment never changes. Every month in the schedule adds the same amount, and that is a property of the engine, not just of this salary. The $184,500 Social Security wage base and the $200,000 Additional Medicare threshold are applied to annual wages first, and only then is the annual result divided across twelve months. A real payroll ledger would show take-home step up in the month Social Security stops; this schedule never does. At $75,000 the point is academic, because gross reaches neither limit. Above $184,500, or above $200,000 filing single, it would matter and this schedule would still run flat.

$52,925.25 is what a year leaves in Oregon, the lowest take-home of the fifty states at this salary. The $18,574.75 total is the trade Oregon makes for taxing no purchases.

Oregon's top bracket begins at $125,000 of taxable income, a bound fixed in statute rather than indexed, and the salary sweep crosses it cleanly.

At $128,500 of gross salary. The $3,500 deferral leaves $125,000 of taxable wage, exactly the top of the 8.75% band. Oregon tax for the year is $10,618.50, $408.40 per bi-weekly check, and annual take-home is $85,817.25.

At $128,600, one hundred dollars later. Taxable wage is $125,100 and the last $100 is charged at 9.9%. Oregon tax rises to $10,628.40, $408.78 per check, and annual take-home to $85,875.70. The step costs $9.90 of state tax on $100 of salary against $8.75 the moment before.

Each additional $1,000 of salary at the baseline. From $75,000 to $76,000, annual take-home moves from $52,925.25 to $53,541.25. Only $616.00 of the raise survives, the least of any state in this family, and $87.50 of the $384.00 lost is Oregon's alone.

The reverse question: how much salary sits inside the 8.75% band? Taxable wage from $11,400 to $125,000, which at the default deferral means gross salary from $14,900 to $128,500. That single band covers nearly every full-time Oregon wage, so for most filers Oregon behaves as a flat 8.75% marginal state with a small discount on the first $11,400.

Right method against wrong method. Applying Oregon's 9.9% headline top rate to the $71,500 taxable wage gives $7,078.50. Applying the 8.75% band rate to the whole wage gives $6,256.25. The engine returns $5,937.25, walking 4.75% then 6.75% then 8.75%. The top-rate shortcut overstates Oregon withholding by $1,141.25 a year and the single-band shortcut by $319.00.

What the state figure excludes. The engine applies no Oregon standard deduction or exemption credit before the bracket walk. It also does not model the statewide transit tax or the Paid Leave Oregon contribution, both withheld on the same stub, nor the Portland-area Metro and Multnomah County income taxes. The $228.36 per-check state line is the income tax alone.

What Filing Jointly Is Worth Against Oregon's 8.75% Band

The filing status selector now drives the Oregon line as well as the federal one. At $75,000 with a $3,500 pre-tax election on a bi-weekly schedule, Oregon withholding is $228.36 per check filing single and $216.09 filing jointly, a saving of $12.27. Federal withholding falls from $265.38 to $162.31 across the same change, lifting the net paycheck from $2,035.59 to $2,150.93 and annual take-home from $52,925.25 to $55,924.25, a gain of $2,999.00. Oregon stays the heaviest state line in this batch under either status: even a joint filer's $216.09 per check exceeds every other state here filing single, because the 8.75% band opens at $11,400 single and $22,800 joint, so a $71,500 taxable base is inside it either way.

• Local municipal, city, or county wage taxes where applicable.
• Post-tax wage garnishments (child support, tax levies, student loans).
• Voluntary post-tax deductions (Roth 401k, charitable giving, supplemental insurance).

• Confusing Bi-Weekly with Semi-Monthly Pay: Bi-weekly pay results in 26 paychecks per year (two 3-paycheck months), whereas semi-monthly pay results in 24 equal paychecks.
• Failing to Update Form W-4: Inaccurate withholding allowances on Form W-4 can lead to substantial underpayment penalties or large unexpected tax bills.
• Forgetting Pre-Tax Deduction Benefits: Contributions to 401(k) and HSA accounts directly reduce taxable income, lowering both federal and state tax burdens.
• Overlooking Additional Medicare Tax: Failing to anticipate the 0.9% surtax on high-earning households with multiple income sources.
