How to Use This Calculator
Enter your income, filing status, and any deductions. The calculator computes your Oregon state income tax alongside your federal tax, showing exactly how much goes to each and what you take home.
The most useful thing to try? Compare different income levels to see how Oregon's brackets affect your tax bill, then look at how combined federal + state taxes shape your total take-home pay.
Here's what each field means:
Annual Income is your total earnings before any taxes. Include wages, freelance income, investment income, and any other sources.
Filing Status determines which set of tax brackets and deductions apply. Oregon uses filing statuses similar to the federal system — single, married filing jointly, married filing separately, and head of household.
Oregon Income Tax: What You Need to Know
Oregon uses a progressive income tax system with rates ranging from 4.75% to 9.9%. Like the federal system, this means your income is taxed in layers — each bracket only applies to the income within that range, not your entire income.
Oregon Tax Brackets (Single Filers)
| Taxable Income | Tax Rate |
|---|---|
| $0 - $4,050 | 4.75% |
| $4,050 - $10,200 | 6.75% |
| $10,200 - $125,000 | 8.75% |
| $125,000+ | 9.9% |
Married Filing Jointly
| Taxable Income | Tax Rate |
|---|---|
| $0 - $8,100 | 4.75% |
| $8,100 - $20,400 | 6.75% |
| $20,400 - $250,000 | 8.75% |
| $250,000+ | 9.9% |
A Real Example
Let's say you're a single filer earning $80,000 in Oregon. After applying the standard deduction of $2,745, your income flows through each bracket:
Your approximate Oregon state income tax would be around $6,036, for an effective state tax rate of about 7.5%.
Remember, this is just the state portion. You'll also owe federal income tax and FICA taxes on top of this.
Deductions and Exemptions
Standard Deduction: Oregon offers a standard deduction of $2,745 for single filers and $5,495 for married couples filing jointly.
Oregon standard deduction (very low), federal tax credit (capped at $7,050), personal exemption credit, Oregon EITC (12% of federal). Oregon allows a credit for income taxes paid to other states.
Local Taxes
Yes — the Portland Metro area (Multnomah County) has two significant local taxes: a Multnomah County Preschool For All personal income tax (1.5% on income over $125,000 single / $200,000 MFJ, with an additional 1.5% over $250,000/$400,000), and a Metro Supportive Housing Services tax (1% on income over $125,000 single / $200,000 MFJ). Together, these can add up to 4% for high Portland-area earners.
What's Unique About Oregon
Oregon has the fourth-highest top income tax rate in the nation at 9.9%. What makes Oregon's system particularly impactful is that the 8.75% bracket starts at just $10,200 for single filers — meaning most working Oregonians are paying close to the top rate on the majority of their income. Oregon compensates somewhat by having no sales tax, making it one of only five states with no statewide sales tax. Oregon's standard deduction is very low ($2,745 single), which means more of your income is exposed to these high rates. Oregon also does not tax Social Security benefits.
Recent Changes
The Portland Metro area taxes are relatively new (2021-2023) and have significantly increased the total tax burden for high earners in the Portland area. State rates have been stable.
