Oregon's income tax system and your rate

Oregon taxes income at rates between 4.75% and 9.9%, depending on how much you earn. The state uses a progressive tax system, meaning higher earners pay a higher percentage. Your rate depends on your filing status (single, married filing jointly, married filing separately, or head of household) and your total taxable income for the year.

Oregon is one of the few states that does not have a sales tax, so income tax is the state's primary way of funding schools, roads, and public services. This means Oregon residents typically pay more in income tax than residents of states with sales tax but lower income tax rates.

The Oregon Department of Revenue sets the tax brackets each year and adjusts them for inflation. If you work in Oregon or live there, you file a state return in addition to your federal return. Self-employed people, retirees with investment income, and employees all owe Oregon income tax on their earnings.

Key Takeaways

  • Oregon's income tax rates range from 4.75% to 9.9% and increase as your income rises.
  • Your tax bracket depends on your filing status and total taxable income, which the state adjusts for inflation each year.
  • Oregon has no sales tax, so state income tax funds most public services.
  • You must file an Oregon state return if you earned income in the state or lived there during the tax year.

The six Oregon tax brackets for 2024

Oregon's six tax brackets explore differently based on whether you file as single, married filing jointly, married filing separately, or head of household. The lowest bracket starts at 4.75% and applies to the smallest income amounts. Each bracket above it increases by roughly 0.99 percentage points until you reach the top rate of 9.9%.

For single filers in 2024, the 4.75% rate applies to income up to $3,750. The 6.75% rate applies to income between $3,750 and $9,450. The brackets continue to climb, with the highest 9.9% rate explore to income over $125,000. If you file as married filing jointly, the income ranges are wider — for example, the top bracket begins at $250,000 instead of $125,000.

Married filing separately filers use the same ranges as single filers, which often results in a higher total tax bill than filing jointly. Head of household filers have their own bracket structure, which falls between single and married filing jointly. Oregon publishes updated bracket amounts each January on the Department of Revenue website.

What counts as Oregon taxable income

Oregon taxable income includes wages, salaries, tips, self-employment income, interest, dividends, capital gains, rental income, and retirement distributions. If you earned money in Oregon or lived in the state while earning money elsewhere, that income is subject to Oregon tax.

Some income is excluded from Oregon taxes. Social Security benefits are not taxed by Oregon, even though they may be taxed federally. Certain retirement account contributions, like traditional 401(k) and IRA deposits, reduce your taxable income. Oregon also allows deductions for federal income tax paid, which can lower your state tax bill.

If you moved to Oregon partway through the year, you only pay tax on income earned while you were a resident. If you moved out of Oregon, you only pay tax on income earned before you left. The state considers you a resident if you lived in Oregon for more than nine months of the tax year, though other factors like employment and property ownership can affect residency status.

Filing requirements and important date

You must file an Oregon state return if your income exceeds the filing threshold for your age and filing status. For 2024, a single person under 65 with income over $4,700 must file. The threshold is higher for married filers and for people 65 and older. Even if you do not owe tax, filing may be worth it if you paid taxes throughout the year — you could receive a refund.

Oregon uses the same filing important date as the federal government: April 15 of the following year. If you file your federal return late, your Oregon return is also late. You can request an extension, which gives you until October 15 to file, but extensions do not extend the important date to pay taxes owed. If you owe money, interest and penalties begin accruing on April 16.

You can file by mail, electronically through approved software, or through a tax professional. Oregon offers free filing options for households earning below a certain income threshold through the Oregon Volunteer Income Tax information (VITA) program, which operates through community organizations and libraries.

Tax credits that reduce what you owe

Oregon offers several tax credits that directly reduce your tax bill. The Oregon Earned Income Tax Credit (EITC) is available to low- and moderate-income workers and is often larger than the federal credit. The Working Family Household and Dependent Care Expense Credit helps offset childcare costs. The Dependent Exemption Credit provides a flat amount per dependent, though the value is modest.

Oregon also offers credits for education expenses, retirement savings, and energy-efficient home improvements. Some credits are refundable, meaning you receive money back even if you owe no tax. Others are non-refundable, meaning they can only reduce your tax bill to zero. The Oregon Department of Revenue website lists all available credits and the income limits for each.

To claim a credit, you typically report it on your state return using a specific form or line. Some credits require documentation — for example, the childcare credit requires the provider's tax ID number. Keeping receipts and records for three years after you file is standard practice in case the state requests proof.

Deductions that lower your taxable income

Oregon allows you to take either the standard deduction or itemize deductions, similar to federal tax rules. The standard deduction for 2024 is $2,500 for single filers and $5,000 for married filing jointly filers. If you are 65 or older, you receive an additional standard deduction amount. Many people use the standard deduction because it is simpler and often results in a lower tax bill than itemizing.

If you itemize, you can deduct mortgage interest, property taxes, charitable donations, and medical expenses that exceed a threshold. Oregon also allows a deduction for federal income tax paid, which is unique among states. This deduction can be significant if you owe federal tax, because it reduces your Oregon taxable income dollar-for-dollar.

Self-employed people can deduct business expenses, including a portion of health insurance premiums, home office costs, and vehicle mileage. You report these deductions on Schedule C, which you attach to your Oregon return. Keeping detailed records of all business expenses throughout the year makes filing easier and ensures you do not miss deductions you are may have access to to claim.

Special situations: part-year residents and nonresidents

If you moved to Oregon during the year, you are a part-year resident and only pay Oregon tax on income earned while you lived in the state. You must report the date you moved and calculate your income for only the months you were a resident. If you moved out of Oregon, the same rule applies — you only owe tax on income earned before you left.

Nonresidents who earned income in Oregon must file an Oregon return even if they do not live there. This includes people who worked in Oregon for part of the year or had rental property in the state. Nonresidents use a different form and calculation method than residents, and they may be able to claim a credit for taxes paid to another state to avoid double taxation.

Military members stationed in Oregon are generally not considered Oregon residents for tax purposes, even if they live on base there. However, spouses and dependents may have different rules. If you are military or have a complex residency situation, contacting the Oregon Department of Revenue directly can clarify your filing status.

Frequently Asked Questions

Do I have to pay Oregon income tax if I work remotely for an out-of-state company?

Yes, if you live in Oregon and work remotely, you owe Oregon income tax on your wages. Your employer's location does not matter — Oregon taxes income earned by residents, regardless of where the employer is based. You may also owe tax to the state where your employer is located, but you can claim a credit for taxes paid to another state to reduce double taxation.

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

The Oregon Department of Revenue can assess penalties and interest on unpaid taxes. Penalties start at 5% of the unpaid tax and can increase. Interest accrues daily at a rate set by the state. If you owe a significant amount, the state can place a lien on your property or garnish your wages. Filing late is better than not filing at all — you can request an extension or file as soon as you are able.

Can I claim Oregon tax credits if I am a part-year resident?

Some credits are available to part-year residents, but you must prorate them based on the number of months you lived in Oregon. For example, if you lived in Oregon for six months, you may claim half of a credit. Other credits have specific rules about part-year residency. Check the instructions for each credit you plan to claim, or contact the Oregon Department of Revenue for guidance.

Is Oregon income tax withheld from my paycheck automatically?

Yes, if you work in Oregon, your employer withholds Oregon income tax from your paycheck based on the W-4 form you complete. You can adjust your withholding if you expect to owe more or less tax at the end of the year. If too much is withheld, you receive a refund when you file. If too little is withheld, you owe money when you file.

What is the Oregon Department of Revenue phone number if I have questions?

The Oregon Department of Revenue operates a tax information line during business hours. You can find the current phone number and hours on the department's website. For complex questions, you may also request a consultation by mail or email. The VITA program offers free in-person help at libraries and community organizations for people who may have access to.
