How Oregon state tax withholding works
Oregon taxes wage income, so your employer withholds Oregon income tax from each paycheck in addition to federal tax. You tell your employer how much to withhold on Form OR-W-4 (Oregon Employee’s Withholding Statement and Exemption Certificate), the state’s counterpart to the federal Form W-4.
For 2026, Oregon uses graduated tax rates. Each rate applies only to the income within its band — the single-filer schedule is:
| Rate | Taxable income over |
|---|---|
| 4.75% | $0 |
| 6.75% | $4,550 |
| 8.75% | $11,400 |
| 9.9% | $125,000 |
Oregon’s standard deduction is $2,910 (single) and $5,820 (married filing jointly).

Oregon vs. federal withholding
Your Oregon and federal withholding are figured separately. Federal withholding follows the IRS Publication 15-T tables and your Form W-4; Oregon withholding follows the state’s own rates and your Form OR-W-4. Getting one right doesn’t guarantee the other — this calculator handles both so you don’t owe a surprise bill to either the IRS or Oregon.
Important Oregon notes
- Oregon allows a federal-tax subtraction in its withholding formula that this estimate does not apply, so actual withholding may be slightly lower. Some localities (e.g., Portland metro) levy additional taxes.
