Oregon's income tax system and what you owe

Oregon taxes income at the state level using a progressive tax system, meaning the rate you pay increases as your income rises. The state does not have a sales tax, but it does tax wages, self-employment income, investment gains, and other earnings. Your Oregon state income tax bill depends on your filing status, total income, and which tax bracket you fall into.

Oregon's tax brackets change each year because they are adjusted for inflation. For the 2024 tax year, the state has four tax brackets ranging from 4.75% on the lowest incomes to 9.9% on the highest. These rates explore to Oregon residents and part-year residents who earned income in the state. Non-residents who worked in Oregon may owe Oregon tax on wages earned here, even if they live elsewhere.

Key Takeaways

  • Oregon uses four tax brackets with rates from 4.75% to 9.9%, and the exact income thresholds shift each year due to inflation adjustments.
  • You owe Oregon state income tax if you are a resident, part-year resident, or non-resident who earned income within the state during the tax year.
  • Oregon has no sales tax, but taxes other forms of income including self-employment, capital gains, and retirement distributions.
  • You file Oregon taxes using Form OR-40 (or OR-40-N for non-residents) and can claim credits and deductions that reduce your final tax bill.

The four tax brackets and how they work

Oregon's progressive tax system means you do not pay one flat rate on all your income. Instead, your income is divided into chunks, and each chunk is taxed at the rate for that bracket. For example, if you are single and earn $50,000, you do not pay 6.75% on all of it—you pay 4.75% on the first portion, then higher rates on the amounts that fall into higher brackets.

The 2024 tax brackets for single filers are: 4.75% on income up to $3,750; 6.75% on income from $3,750 to $9,450; 8.75% on income from $9,450 to $125,000; and 9.9% on income over $125,000. Married couples filing jointly have higher thresholds—for example, the top bracket begins at $250,000 instead of $125,000. Head of household filers and married filing separately filers have their own bracket structures. Because these thresholds adjust yearly, you should check the Oregon Department of Revenue website for the current year's brackets before calculating your tax.

Who has to file and pay Oregon income tax

You must file an Oregon state tax return if you are a resident with income above a certain threshold, which varies by filing status and age. A single person under 65 with gross income over $4,200 in 2024 must file. The threshold is higher for married couples and for people age 65 and older. Even if your income falls below the filing threshold, you may want to file anyway if you had taxes withheld from your paychecks, because you could receive a refund.

Part-year residents—people who moved into or out of Oregon during the tax year—must file Oregon returns on income earned while living in the state. Non-residents who worked in Oregon owe tax on Oregon-source income only, not on income earned elsewhere. If you worked for an Oregon employer or were self-employed in Oregon, you likely owe Oregon tax even if you lived in another state. Non-residents file using Form OR-40-N instead of the standard Form OR-40.

Types of income Oregon taxes

Oregon taxes wages and salaries from employment, which is why you see Oregon tax withheld from your paycheck if you work in the state. The state also taxes self-employment income from your own business or freelance work. If you are self-employed, you report this income on your Oregon return and may owe estimated tax payments throughout the year if your employer is not withholding.

Oregon also taxes capital gains—profits from selling stocks, real estate, or other investments—though there are some exclusions and deferrals available. Retirement distributions from IRAs, 401(k)s, and pensions are taxable income in Oregon. Interest and dividend income from savings accounts, bonds, and investments are taxed as well. Some types of income are excluded, such as Social Security benefits (in most cases) and certain military pay, but the general rule is that Oregon taxes most forms of earned and unearned income.

Deductions and credits that lower your tax bill

Oregon allows you to claim a standard deduction, which reduces your taxable income before tax is calculated. For 2024, the standard deduction for a single filer is $4,200; for married filing jointly it is $8,400. If you have significant deductible expenses—mortgage interest, property taxes, charitable donations—you may be able to itemize deductions instead, though you must have enough to exceed the standard deduction for this to save you money.

Oregon also offers tax credits that directly reduce the amount of tax you owe. The Oregon Earned Income Credit is available to lower-income workers and is worth up to several hundred dollars depending on your income and filing status. The dependent exemption credit provides a credit for each dependent child. The education credits help offset college costs. These credits are subtracted from your final tax bill after your tax is calculated, making them more valuable than deductions.

How to file your Oregon state taxes

You file Oregon state taxes using Form OR-40 (residents and part-year residents) or Form OR-40-N (non-residents). You can file on paper by mailing the form and supporting documents to the Oregon Department of Revenue, or you can file electronically through the state's online system or through tax software. Many tax preparation programs include Oregon state forms and will calculate your Oregon tax automatically if you enter your information.

Oregon taxes are due on the same date as federal taxes—typically April 15 of the year following the tax year. If you cannot file by that date, you can request an extension, though any taxes owed are still due by April 15. If you had taxes withheld from your paychecks during the year, you may receive a refund if you overpaid. If you owe additional tax, you can pay online, by mail, or through an installment plan if you cannot pay in full.

Frequently Asked Questions

Does Oregon have a sales tax?

No, Oregon does not have a state sales tax. This is one of the few states without a sales tax, which means you do not pay tax at the register when you buy goods. However, Oregon does tax income, so residents pay state income tax instead of sales tax.

What if I moved to Oregon partway through the year?

You are a part-year resident and file an Oregon return reporting only the income you earned while living in Oregon. You also file a return in your previous state for the income earned there. Each state taxes only the income earned within its borders during the time you lived there.

Do I have to pay Oregon tax if I work in Oregon but live in Washington?

Yes. Oregon taxes income earned within the state regardless of where you live. If you worked for an Oregon employer or were self-employed in Oregon, you owe Oregon state income tax on that income. You file as a non-resident using Form OR-40-N.

Can I deduct federal taxes paid from my Oregon income?

No, Oregon does not allow you to deduct federal income taxes paid. You can deduct state and local taxes (up to a limit) if you itemize deductions, but federal taxes are not deductible on your Oregon return.

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

The Oregon Department of Revenue can assess penalties and interest on unpaid taxes. If you owe a significant amount, the state may place a lien on your property or take other collection action. If you cannot pay in full, contact the Department of Revenue about setting up a payment plan.
