Oregon has a state income tax, and it is one of the highest rates in the country

Oregon taxes the income of residents and non-residents who earn money in the state. The state uses a progressive tax system, meaning the tax rate increases as your income rises. Oregon has no sales tax, but it makes up for that with income tax. If you live in Oregon or work there, you will owe state income tax on wages, self-employment income, interest, dividends, and other earnings.

The state tax year runs the same as the federal tax year: January 1 through December 31. You file Oregon taxes using Form OR-40 (the Oregon Individual Income Tax Return) if you are a resident, or Form OR-40-N if you are a non-resident with Oregon income. Both forms are due by April 15 unless you request an extension.

Key Takeaways

  • Oregon residents pay state income tax on all income, including wages, self-employment earnings, interest, and dividends, using a progressive tax rate structure.
  • Oregon has no state sales tax, but state income tax rates range from 4.75% to 9.9% depending on your income bracket and filing status.
  • You file Oregon taxes on Form OR-40 (residents) or Form OR-40-N (non-residents) by April 15 each year, the same important date as federal taxes.
  • Oregon offers a standard deduction that varies by age and filing status, and you can deduct federal income tax paid when calculating Oregon taxable income.

Oregon income tax brackets and rates for the current tax year

Oregon uses tax brackets that change each year based on inflation. The state publishes updated brackets in January for the tax year that just ended. For example, in 2023, Oregon had five tax brackets for single filers: 4.75% on income up to $3,750, 6.75% on income from $3,751 to $9,450, 8.75% on income from $9,451 to $121,500, 9.9% on income from $121,501 to $305,000, and 9.9% on income over $305,000.

The brackets are different for married filing jointly, married filing separately, and head of household filers. Oregon's Department of Revenue publishes the current year's brackets on its website each January. Because the brackets shift annually, you should check the department's site or your tax software to find the exact brackets for the year you are filing.

Oregon's top rate of 9.9% applies only to the portion of income that falls into the highest bracket, not your entire income. This is how a progressive system works: you pay the lowest rate on the first dollars you earn, then higher rates only on income above each threshold.

Standard deduction and personal exemptions in Oregon

Oregon allows a standard deduction that depends on your age and filing status. For 2023, the standard deduction for a single filer under 65 was $4,890, and for a single filer 65 or older it was $6,190. Married filing jointly filers had a standard deduction of $9,780 if both spouses were under 65, and higher amounts if one or both were 65 or older. These amounts change each year.

You can also deduct federal income tax you paid during the year when calculating your Oregon taxable income. This is a significant deduction that many states do not allow. Oregon does not allow a deduction for state income tax you paid.

If your income is below the standard deduction for your filing status, you may not owe Oregon income tax at all. You can find the current year's standard deduction amounts on the Oregon Department of Revenue website or in the instructions that come with Form OR-40.

Who must file an Oregon tax return

You must file an Oregon return if your income exceeds the standard deduction for your filing status, or if you had Oregon income tax withheld from your paychecks. Even if you do not owe tax, filing may be worth doing if you had taxes withheld, because you could receive a refund.

Non-residents who earned income in Oregon must also file, even if they live in another state. This includes people who worked in Oregon for part of the year or had business income from Oregon sources. Non-residents file Form OR-40-N and report only the income earned in Oregon, not income from other states.

Oregon residents who are claimed as dependents on someone else's return may still need to file their own return if they had earned income or unearned income above certain thresholds. The Form OR-40 instructions list the specific income limits for dependents.

Tax withholding and estimated payments

If you are an employee, your employer withholds Oregon income tax from your paycheck based on the W-4 form you complete. The amount withheld depends on your income, filing status, and the number of allowances you claim. You can adjust your withholding at any time by submitting a new W-4 to your employer.

If you are self-employed or have income that is not subject to withholding, you may need to make quarterly estimated tax payments to Oregon. These payments are due on April 15, June 15, September 15, and January 15. You calculate estimated payments using Form OR-ES, which the Oregon Department of Revenue provides on its website.

If you do not pay enough tax throughout the year through withholding or estimated payments, you may owe a penalty when you file your return. Oregon allows you to avoid this penalty if your withholding and estimated payments equal at least 90% of the current year's tax or 100% of the prior year's tax, whichever is smaller.

Oregon tax credits and deductions you may use

Oregon offers several tax credits that reduce the amount of tax you owe. The Earned Income Tax Credit (EITC) is available to low- and moderate-income workers and is calculated based on federal EITC rules. Oregon also offers a dependent exemption credit, a child and dependent care credit, and credits for property taxes or rent paid by low-income residents.

In addition to the standard deduction and federal income tax deduction, Oregon allows deductions for charitable contributions, mortgage interest, and certain business expenses if you are self-employed. You can itemize deductions instead of taking the standard deduction if your itemized deductions are larger, using Schedule A.

Oregon also has a Working Family Household and Dependent Care Expense Credit for families who pay for childcare or adult care so they can work. The credit is calculated on Form OR-10, and the amount depends on your income and the expenses you paid.

How to file your Oregon tax return

You can file your Oregon return on paper by mailing Form OR-40 or OR-40-N to the Oregon Department of Revenue, or you can file electronically using tax software or a tax professional. Electronic filing is faster and reduces the chance of errors. The Oregon Department of Revenue website lists approved tax software providers that can file Oregon returns.

If you file on paper, mail your return to the address shown in the Form OR-40 instructions. Keep a copy for your records. If you file electronically, you will receive confirmation of receipt from the Oregon Department of Revenue within a few days.

If you cannot file by April 15, you can request an extension using Form OR-40-EXT. An extension gives you until October 15 to file, but it does not extend the important date to pay any tax you owe. You should pay as much as you can by April 15 to avoid interest and penalties on the unpaid balance.

Frequently Asked Questions

Does Oregon have sales tax?

No, Oregon has no state sales tax. However, some cities and counties in Oregon impose local sales taxes on certain items. The state compensates for the lack of sales tax with higher income tax rates compared to many other states.

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

Yes, you must pay Oregon income tax on income you earned in Oregon. You file Form OR-40-N as a non-resident and report only the income earned in Oregon. You may also owe tax to the state where you live, but most states allow a credit for taxes paid to other states to avoid double taxation.

What is the Oregon Earned Income Tax Credit?

Oregon's EITC is a refundable tax credit for low- and moderate-income workers. The amount is based on federal EITC rules and your filing status and income. You claim it on Form OR-40 using the same income and family information you use for the federal EITC.

Can I deduct federal income tax on my Oregon return?

Yes, Oregon allows you to deduct federal income tax paid during the year. This is one of the few states that allows this deduction. You report the deduction on Form OR-40, and it reduces your Oregon taxable income.

What happens if I do not file an Oregon tax return?

If you owe tax and do not file, the Oregon Department of Revenue may assess penalties and interest on the unpaid amount. The department can also file a return on your behalf based on information it receives from employers or other sources, though this return may not include deductions or credits you are may have access to to.
