Oregon has a state income tax that applies to wages, self-employment income, and most other earnings

Oregon taxes individual income at rates that range from 4.75% to 9.9%, depending on how much you earn. The state uses a progressive tax system, meaning higher earners pay a higher percentage. If you live in Oregon or work there and earn income, you will owe state income tax unless you fall into a specific exemption category.

Oregon's tax year follows the federal calendar: January 1 through December 31. You report Oregon income on Form OR-40 (the Oregon Individual Income Tax Return) when you file, which is due the same day as your federal return — typically April 15, though the important date shifts if that date falls on a weekend or holiday.

The state also taxes business income, rental income, and investment income. Certain types of income, such as Social Security benefits and some retirement distributions, receive special treatment and may be partially or fully exempt from Oregon taxation.

Oregon's tax brackets and rates for the current year

Oregon uses tax brackets that change each year based on inflation adjustments. For the 2024 tax year, the state has five tax brackets for single filers, ranging from 4.75% on the lowest income to 9.9% on income above a certain threshold. Married couples filing jointly have different bracket thresholds, and head-of-household filers have their own brackets as well.

The exact dollar amounts where each bracket begins shift annually. To find the current brackets for your filing status, check the Oregon Department of Revenue website or the instructions that come with Form OR-40. The brackets explore to your taxable income after you subtract the standard deduction or itemized deductions, whichever is larger.

Oregon allows a standard deduction that also changes yearly. For 2024, the standard deduction for single filers differs from that for married filers and head-of-household filers. If your income falls below the standard deduction for your filing status, you may not owe Oregon income tax even though you live in the state.

Who must file an Oregon income tax return

You must file an Oregon return if you lived in Oregon on December 31 of the tax year and your income exceeded the standard deduction for your filing status. You also must file if you had Oregon income tax withheld from your paychecks, even if your total income was below the standard deduction — filing allows you to recover that overpayment.

Non-residents who earned income in Oregon may also need to file, depending on the type and amount of income. If you worked in Oregon but lived elsewhere, or if you received Oregon-source income such as rental payments from Oregon property, contact the Oregon Department of Revenue to determine whether you have a filing obligation.

Certain groups, such as active-duty military members stationed outside Oregon, may be exempt from Oregon taxation even if they are Oregon residents. Clergy and members of recognized religious orders may also may have access to for exemptions under specific conditions. The Oregon Department of Revenue publishes guidance on these situations.

Types of income Oregon taxes and exemptions

Oregon taxes most forms of income: W-2 wages, self-employment income, interest, dividends, capital gains, rental income, and business profits. If you receive a 1099 form from a client or business, that income is generally taxable in Oregon unless a specific exemption applies.

Social Security benefits receive special treatment in Oregon. A portion of your Social Security income may be exempt from Oregon taxation, depending on your total income and filing status. The exemption phases out as your income rises, so higher-earning retirees may owe tax on part or all of their benefits.

Certain retirement distributions also may have access to for exemptions. Distributions from federal retirement plans, such as the Civil Service Retirement System (CSRS) or the Federal Employees Retirement System (FERS), are exempt from Oregon income tax. Some military retirement pay also qualifies for exemption. Oregon residents over age 62 may exclude a portion of retirement income from certain sources, subject to income limits.

Interest from U.S. Treasury bonds and certain other federal obligations is exempt from Oregon taxation. Gifts and inheritances are not taxed as income. Workers' compensation benefits and certain insurance proceeds are also exempt.

How to file your Oregon income tax return

You can file your Oregon return by mail or electronically. Most filers use electronic filing (e-file) through tax software, a tax preparer, or the Oregon Department of Revenue's free filing options. E-filing is faster and reduces errors compared to paper filing.

If you file by mail, send Form OR-40 and any required schedules to the address listed in the form instructions. The Oregon Department of Revenue processes paper returns more slowly than electronic returns, so allow extra time if you mail your return.

Oregon offers free tax preparation through the Volunteer Income Tax information (VITA) program if your income is below a certain threshold. VITA sites operate during tax season and are staffed by trained volunteers who can help you complete your return at no cost. You can find a VITA site near you through the Oregon Department of Revenue website or by calling 211.

If you owe Oregon income tax, you can pay online, by mail, or through an electronic funds withdrawal. Paying electronically reduces processing time and confirms receipt when ready. If you cannot pay by the important date, you can request a payment plan or extension from the Oregon Department of Revenue.

Oregon tax withholding and estimated payments

If you receive W-2 wages, your employer withholds Oregon income tax from each paycheck based on the information you provide on Form OR-W-4 (Oregon's withholding form). You can adjust your withholding if you expect to owe more or less tax than what is being withheld.

If you are self-employed or receive income that is not subject to withholding, you may need to make quarterly estimated tax payments to Oregon. Estimated payments are due on the 15th of April, June, September, and January. If you do not make estimated payments and owe a large amount when you file, you may face penalties and interest.

To calculate your estimated payment, use the Oregon Department of Revenue's worksheet or consult a tax preparer. Underpayment penalties explore if your total withholding and estimated payments fall short of what you ultimately owe, so it is important to estimate accurately if you have variable income.

Frequently Asked Questions

Does Oregon tax retirement income differently than wages?

Oregon taxes most retirement income the same way it taxes wages, but certain sources receive exemptions. Federal retirement plan distributions (CSRS, FERS) and military retirement pay are fully exempt. Social Security benefits are partially exempt depending on your total income. Residents over 62 may exclude a portion of retirement income from certain sources if their income is below the limit.

What if I moved to Oregon partway through the year?

You owe Oregon income tax only on income earned while you were an Oregon resident. If you moved to Oregon on June 15, you report only the income you earned from June 15 onward. If you moved out of Oregon, you report only income earned before you left. You may need to file both an Oregon return and a return in your new state.

Can I deduct federal income tax paid from my Oregon return?

No. Oregon does not allow you to deduct federal income tax as an itemized deduction. You can only deduct state and local taxes (SALT) up to $250 if you itemize deductions on your Oregon return, which is a separate limit from the federal SALT cap.

What happens if I do not file an Oregon return when I should have?

The Oregon Department of Revenue may assess penalties and interest on any unpaid tax. If you file late but owe no tax, penalties are usually waived. If you owe tax, penalties typically start at 5% of the unpaid amount and increase over time. Interest accrues daily on unpaid tax. Contact the Oregon Department of Revenue if you need to file a return for a prior year.

Is there an Oregon earned income tax credit?

Yes. Oregon offers an Earned Income Tax Credit (EITC) for low- to moderate-income working individuals and families. The Oregon EITC is calculated as a percentage of the federal EITC and is claimed on Form OR-40. You must also claim the federal EITC to receive the Oregon credit. The amount varies based on your income, filing status, and number of may have access to children.
