Oregon Paycheck Calculator

How the Oregon estimate works

Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Oregon annualizes wages and federal income tax withholding, applies the 2026 Form OR-W-4 schedule, federal-tax subtraction phase-out, standard deduction, and allowance credit, then returns the result to the selected pay period. Statewide Transit Tax, Paid Leave Oregon, and the employee Workers’ Benefit Fund share remain separate lines. Confirmed Eugene, Metro SHS, and Multnomah PFA payroll withholding follows each program’s employer rule or an explicit employee election.

Example: The detailed steps in Oregon’s official $25,000 annual-wage example produce a $21,090 base and $1,789 of rounded annual withholding. WageFrame follows those detailed steps and the operative 2026 tables; it does not copy the inconsistent base and prior-year cap text that also appears in the source PDF. The calculator does not assume any unentered benefit deduction or invent a tax result.

Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.

Which Oregon local taxes are included? Eugene employee payroll tax is based on a confirmed primary work location and the pay-date threshold. Metro SHS and Multnomah PFA use the employer payroll-withholding threshold unless the employee has an explicit opt-out or designated amount. TriMet, Lane Transit, and Portland Arts Tax are not employee payroll withholding in this calculation.
