Yes, Oregon has a state income tax

Oregon taxes the income of residents and non-residents who earn money within the state. The tax applies to wages, self-employment income, interest, dividends, and other forms of income. Oregon's income tax rates range from 4.75% to 9.9% depending on your income level — the state uses a progressive tax system, meaning higher earners pay a higher percentage.

Unlike some states, Oregon does not have a flat tax rate. Your actual tax bill depends on your filing status (single, married filing jointly, head of household) and your total taxable income for the year. You report Oregon income tax on your state return, which you file separately from your federal return.

Oregon income tax brackets and rates for 2024

Oregon's tax brackets change each year based on inflation adjustments. For the 2024 tax year, the state income tax rates are 4.75%, 6.75%, 8.75%, and 9.9%. Which bracket you fall into depends on your taxable income and filing status.

A single filer with $3,750 or less in taxable income pays 4.75%. Income between $3,751 and $9,450 is taxed at 6.75%. Income between $9,451 and $21,900 is taxed at 8.75%. Any income above $21,900 is taxed at 9.9%. These thresholds are different for married couples filing jointly, heads of household, and married couples filing separately — each status has its own bracket structure.

The Oregon Department of Revenue publishes updated brackets each January. If you file your return after the year ends, use the brackets for the tax year you are reporting, not the current year.

Who must file an Oregon income tax return

You must file if your income exceeds Oregon's filing threshold for your age and filing status. For the 2024 tax year, a single person under 65 must file if they had more than $4,050 in income. A single person 65 or older must file if they had more than $5,050 in income. These thresholds are higher for married couples filing jointly and vary by filing status.

Non-residents who earned income in Oregon must also file an Oregon return, even if they do not live in the state. This includes people who worked in Oregon for part of the year or received income from Oregon sources like rental property or business income. Non-residents report only the income earned in Oregon, not income from other states.

If you are claimed as a dependent on someone else's return, the filing threshold may be lower. The Oregon Department of Revenue website lists the exact thresholds for each filing status and age group.

Oregon's standard deduction and deductions you can claim

Oregon allows you to claim either the standard deduction or itemized deductions, similar to the federal system. For the 2024 tax year, the standard deduction for a single filer is $2,440. For married couples filing jointly, it is $4,880. These amounts increase if you are 65 or older or blind.

If you itemize deductions instead of taking the standard deduction, you can deduct state and local taxes (up to $10,000 combined), mortgage interest, charitable contributions, and certain medical expenses. Oregon also allows a dependent exemption of $215 per dependent for the 2024 tax year, though this amount changes annually.

Oregon offers several tax credits that reduce your tax bill directly. The Oregon Earned Income Tax Credit (EITC) is available to low- and moderate-income workers. The dependent and dependent care credit, the education credit, and the residential energy credit are also available under certain conditions. Credits are more valuable than deductions because they reduce your tax dollar-for-dollar rather than reducing your taxable income.

How to file your Oregon income tax return

You can file your Oregon return online through the Oregon Department of Revenue's website, by mail, or through a tax preparer or accountant. The state does not require you to use a specific software, but many commercial tax software programs include Oregon forms and can file electronically on your behalf.

If you file electronically, the Oregon Department of Revenue typically processes your return within two to four weeks. If you mail a paper return, processing takes longer — usually four to six weeks or more during peak filing season. You will receive a confirmation once your return is processed.

You need your Social Security number, W-2 forms from employers, 1099 forms for self-employment or other income, and documentation of deductions you plan to claim. If you are filing as a non-resident, you also need to report which months you worked in Oregon or earned Oregon-source income.

What happens if you do not file or owe Oregon income tax

If you owe Oregon income tax and do not file, the state may assess penalties and interest on the unpaid amount. The failure-to-file penalty is typically 5% of the unpaid tax per month, up to 25%. Interest accrues daily on unpaid tax at a rate set by the Oregon Department of Revenue, which changes quarterly.

If you file late but pay what you owe, the penalty is usually smaller than if you do not file at all. If you expect to owe money, filing on time or requesting an extension before the deadline can reduce penalties. The Oregon Department of Revenue offers a payment plan option if you cannot pay the full amount at once.

If the Oregon Department of Revenue believes you owe tax, they will send you a notice. You have the right to dispute the assessment or request a hearing. Ignoring notices does not make the debt go away — it can result in wage garnishment, bank account levies, or a lien on your property.

Oregon income tax for self-employed people and business owners

If you are self-employed or own a business in Oregon, you report your business income on your Oregon tax return. You can deduct ordinary and necessary business expenses — supplies, equipment, rent, utilities, and other costs directly related to running your business. Self-employed people also pay self-employment tax to fund Social Security and Medicare, which is a federal obligation separate from Oregon state income tax.

Oregon allows you to deduct the self-employment tax you pay when calculating your Oregon taxable income, which reduces your state tax bill. You must keep records of all income and expenses in case the Oregon Department of Revenue audits your return.

Frequently Asked Questions

Do I have to pay Oregon income tax if I live in Washington or another no-income-tax state?

If you live in Washington or another state with no income tax but earned income in Oregon, you owe Oregon tax on that income. Oregon taxes income earned within the state regardless of where you live. You would file an Oregon non-resident return reporting only the income you earned in Oregon.

What is the deadline to file my Oregon income tax return?

The Oregon income tax return deadline is typically April 15, the same as the federal deadline. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. You can request an extension to file by October 15, though an extension to file is not an extension to pay — you still owe tax by April 15 if you expect to owe money.

Can I file my Oregon return if I did not file a federal return?

You can file an Oregon return even if you are not required to file a federal return, though many people file both. If you are owed a federal refund, you should file a federal return to claim it. Some Oregon tax credits require you to have filed a federal return, so check the requirements for any credits you plan to claim.

What if I moved to Oregon partway through the year?

If you moved to Oregon during the tax year, you are a part-year resident. You report income earned before you moved as non-resident income (if it was Oregon-source income) and income earned after you moved as resident income. Oregon has specific rules for determining your residency status based on the number of days you spent in the state.

Does Oregon tax retirement income or Social Security?

Oregon does not tax Social Security benefits. Oregon does tax retirement income from pensions, 401(k) withdrawals, and IRAs, though there are some exemptions for certain types of retirement income depending on your age and income level. Check the Oregon Department of Revenue website for current rules on retirement income exemptions.
