Oregon taxes your income at rates between 4.75% and 9.9%, depending on how much you earn

Oregon has a progressive income tax system, meaning the tax rate increases as your income increases. You do not pay the same percentage on every dollar you make. Instead, your income is divided into brackets, and each bracket is taxed at its own rate. For the 2024 tax year, Oregon's rates range from 4.75% on the lowest bracket to 9.9% on the highest.

Oregon taxes wages, self-employment income, investment income, and retirement distributions. If you live in Oregon or work there, you will owe state income tax on most types of income. The state also taxes capital gains — profits from selling stocks, real estate, or other assets — at a flat 5% rate on gains above $250,000 per year.

Unlike federal income tax, Oregon does not allow you to deduct state and local taxes (SALT) from your state return. This means you cannot reduce your Oregon taxable income by claiming deductions for property taxes or sales taxes paid.

Key Takeaways

  • Oregon's income tax brackets range from 4.75% to 9.9%, with higher rates explore only to income above each threshold.
  • You owe Oregon income tax if you live in the state or earn income there, including wages, self-employment income, and investment gains.
  • Oregon taxes long-term capital gains at a flat 5% rate on gains exceeding $250,000 per year.
  • Oregon allows a standard deduction or itemized deductions to reduce your taxable income, similar to federal tax rules.
  • Retirement income including Social Security, pensions, and IRA withdrawals may be partially or fully taxable depending on your total income.

How Oregon's tax brackets work

Oregon divides income into five tax brackets for single filers and five for married couples filing jointly. The brackets change each year based on inflation. For 2024, a single filer pays 4.75% on income up to $3,750, then 6.75% on income from $3,750 to $9,450, then 8.75% on income from $9,450 to $125,000, then 9.9% on income above $125,000. Married couples filing jointly have higher thresholds at each bracket.

The key point is that you only pay the higher rate on income that falls into that bracket. If you earn $50,000 as a single filer, you do not pay 8.75% on all $50,000. You pay 4.75% on the first $3,750, 6.75% on the next $5,700, and 8.75% on the remaining $40,550. This is called the marginal tax rate — the rate you pay on your last dollar of income — and it is different from your effective tax rate, which is the average rate you pay on all your income.

Oregon publishes updated brackets each January on the Oregon Department of Revenue website. If you file taxes yourself, you will find the current brackets on the forms and instructions you read.

Deductions and credits that lower what you owe

Before you calculate your tax, Oregon allows you to reduce your income using either the standard deduction or itemized deductions. For 2024, the standard deduction is $2,500 for single filers and $5,000 for married couples filing jointly. If you own a home with a mortgage, pay significant property taxes, or have large charitable donations, itemizing may save you more money than the standard deduction.

Oregon also offers tax credits that directly reduce the amount of tax you owe. The Oregon Earned Income Tax Credit (EITC) is available to low- and moderate-income workers and can return money to you even if you owe no tax. The Working Family Household and Dependent Care Credit helps offset childcare costs. The Dependent Exemption Credit provides a small reduction for each dependent you claim.

Credits are more valuable than deductions because they reduce your tax dollar-for-dollar, whereas deductions only reduce the income that gets taxed. If you have a $1,000 credit, you owe $1,000 less in tax. If you have a $1,000 deduction and you are in the 8.75% bracket, you owe only $87.50 less in tax.

Retirement income and Social Security taxation

Oregon taxes most retirement income, but the rules vary by source. Distributions from traditional IRAs, 401(k)s, and similar retirement accounts are fully taxable as ordinary income. Pensions from your employer are also taxable. However, Oregon offers a pension and retirement income exclusion that may reduce or eliminate tax on some retirement income if you meet age and income requirements.

Social Security benefits are partially taxable in Oregon if your total income exceeds certain thresholds. The state uses a formula that includes half of your Social Security benefits plus all other income. If that total exceeds $25,000 for single filers or $32,000 for married couples filing jointly, a portion of your benefits becomes taxable. This is the same calculation the federal government uses, but Oregon's thresholds are lower.

If you are 62 or older and receive a pension, you may be able to exclude up to $27,360 of pension income from your Oregon taxes (for 2024). The exclusion phases out for higher incomes. You will need to check the current year's rules and your specific situation to know whether this applies to you.

Self-employment income and quarterly taxes

If you are self-employed, you owe Oregon income tax on your net business income — what you earn minus legitimate business expenses. You also owe federal self-employment tax, which funds Social Security and Medicare. Oregon does not have a separate self-employment tax, but you must include your self-employment income on your state return.

If you expect to owe more than $500 in Oregon income tax for the year, you should make quarterly estimated tax payments. These are due April 15, June 15, September 15, and January 15 of the following year. If you do not pay enough throughout the year, you may owe a penalty when you file your return, even if you ultimately get a refund.

You can pay estimated taxes online through the Oregon Department of Revenue website, by mail, or through your bank. Keep records of what you paid so you can claim credit for those payments when you file your annual return.

Who must file an Oregon tax return

You must file an Oregon return if you live in Oregon and your income exceeds the filing threshold for your filing status. For 2024, the threshold is $2,500 for single filers, $5,000 for married couples filing jointly, and $2,500 for heads of household. If you are claimed as a dependent on someone else's return, the threshold is lower — generally $1,250 or more of earned income, or $450 or more of unearned income.

Even if your income is below the threshold, you should file if you had taxes withheld from your paychecks or made estimated payments. Filing allows you to claim a refund of those overpayments. You should also file if you are due any credits, such as the Earned Income Tax Credit, because you will not receive them unless you file.

If you moved to Oregon during the year or moved out of Oregon, you may owe a partial-year return. Oregon taxes you on income earned while you were a resident. If you moved out, you do not owe tax on income earned after you left, but you do owe tax on income earned before you left.

How to file your Oregon return

You can file your Oregon return on paper using Form OR-40 (the individual income tax return) and supporting schedules, or you can file electronically through the Oregon Department of Revenue's online system or through tax software. E-filing is faster and reduces errors because the software catches common mistakes before you submit.

Oregon offers free tax preparation through the Volunteer Income Tax information (VITA) program if your income is below a certain threshold (usually around $60,000). You can find a VITA site near you through the IRS website or by calling 211. VITA volunteers are trained to prepare both federal and Oregon returns.

The filing important date is April 15 unless that date falls on a weekend or holiday. If you cannot file by the important date, you can request an extension, but an extension to file is not an extension to pay. If you owe tax, you should pay by April 15 to avoid penalties and interest, even if you file late.

Frequently Asked Questions

Do I have to pay Oregon income tax if I work in Oregon but live in another state?

Yes. Oregon taxes income earned within the state, regardless of where you live. However, you may be able to claim a credit on your home state's return for taxes paid to Oregon, so you do not pay tax twice on the same income. Check your home state's rules on out-of-state income.

What happens if I do not file or pay my Oregon taxes on time?

Oregon charges penalties and interest on unpaid taxes. The penalty is typically 5% of the unpaid tax per month, up to 25%. Interest accrues daily at a rate set by the state. If you cannot pay in full, contact the Oregon Department of Revenue about a payment plan. Filing late is better than not filing at all, because the failure-to-file penalty is larger than the failure-to-pay penalty.

Can I deduct federal income taxes from my Oregon return?

No. Oregon does not allow you to deduct federal income taxes, state income taxes, or local taxes from your Oregon taxable income. You can only use the standard deduction or itemize deductions for mortgage interest, property taxes, charitable contributions, and other allowed expenses.

Is Oregon income tax withheld automatically from my paycheck?

Yes, if you work for an employer in Oregon. Your employer withholds Oregon income tax based on the W-4 form you complete. If too much is withheld, you will get a refund when you file. If too little is withheld, you will owe tax. You can adjust your withholding by submitting a new W-4 to your employer.

What is Oregon's capital gains tax and how does it work?

Oregon taxes long-term capital gains — profits from selling assets held more than one year — at a flat 5% rate on gains exceeding $250,000 per year. Short-term gains and gains below the threshold are taxed as ordinary income at your regular tax rate. This applies to stocks, real estate, and other investments, but not to your primary residence if you meet certain conditions.
