Oregon State Income Tax
Understanding the Oregon State Income Tax can be crucial for residents and those doing business in the state. Here’s an in-depth look at the key aspects of Oregon's state income tax, including its structure, rates, deductions, and frequently asked questions.
Overview of Oregon Income Tax
Oregon levies a progressive state income tax on individuals, which means the tax rate increases as income increases. Unlike some states, Oregon does not impose a separate corporate income tax at the state level but does tax corporate income under its Corporate Activity Tax (CAT).
Key Features
- Progressive Tax System: The state income tax is calculated using a tiered tax rate system, where different portions of your income are taxed at different rates.
- No Sales Tax: Oregon is one of the few states that do not have a sales tax, which means the state relies more heavily on income taxes and other forms of taxation.
Oregon Individual Income Tax Rates
Oregon's individual income tax rates for 2023 are as follows:
Income Bracket | Tax Rate |
---|---|
$0 - $3,650 | 4.75% |
$3,651 - $9,200 | 6.75% |
$9,201 - $125,000 | 8.75% |
Over $125,000 | 9.90% |
These brackets apply to single filers and are adjusted for inflation each year. For married couples filing jointly, the brackets are slightly different, generally doubling the income levels.
Example Calculation
For a single filer earning $50,000 annually:
- The first $3,650 is taxed at 4.75%.
- The next $5,550 (from $3,651 to $9,200) is taxed at 6.75%.
- The remaining $40,800 (from $9,201 to $50,000) is taxed at 8.75%.
The total state tax would be the sum of each bracket taxed separately.
Deductions and Credits
Standard Deduction
Oregon offers a standard deduction, which varies depending on filing status:
- Single or Married Filing Separately: Approximately $2,350
- Married Filing Jointly, Head of Household, or Surviving Spouse: Approximately $4,700
Itemized Deductions
Taxpayers can choose to itemize deductions if they exceed the standard deduction. Common deductions include:
- Medical Expenses: Unreimbursed medical expenses are deductible if they exceed a certain percentage of your adjusted gross income (AGI).
- Mortgage Interest and Property Taxes: These deductions are similar to those at the federal level.
Tax Credits
Oregon offers various tax credits that can reduce your tax liability:
- Earned Income Tax Credit (EITC): Available to low- to moderate-income taxpayers with qualifying children.
- Child and Dependent Care Credit: Available to taxpayers who pay for the care of a child or dependent while they work or look for work.
- Working Family Household and Dependent Care Credit: Available to low-income families with dependents.
Filing Requirements
Anyone who lives in Oregon or earns income from an Oregon source must file a state income tax return if their income exceeds the set threshold. Generally, the filing deadline aligns with the federal deadline of April 15th.
Non-Residents and Part-Year Residents
Oregon requires part-year residents and non-residents earning income in the state to file a tax return. They must report all income earned while a resident and any income sourced from Oregon.
Oregon Corporate Income Tax
Corporate Activity Tax (CAT)
The CAT is not purely a corporate income tax but rather a tax on business activity. Introduced in 2019, it applies to companies with commercial activity over $1 million. The key features include:
- Tax Rate: $250 plus 0.57% on gross receipts over $1 million.
- Exemptions: Certain receipts are exempt, like groceries and healthcare.
S-Corporations and LLCs
These entities are generally pass-through entities for state tax purposes, meaning the income is reported on individual owner’s tax returns.
Filing and Payment
Oregon encourages electronic filing for both individuals and corporations. Payment options include payment by check, electronic payment, or a scheduled installment plan.
Penalties for Late Filing or Non-Payment
Oregon imposes penalties for late filing, late payment, or failing to file a return. Interest accrues on any unpaid taxes from the due date until the tax is paid in full.
Frequently Asked Questions
Is there a penalty for underpayment of tax?
Yes, Oregon may impose a penalty for underpayment of estimated taxes if your tax obligation exceeds your withholding and estimated payments by more than $1,000.
How does Oregon handle capital gains?
Oregon taxes capital gains as regular income. However, certain exclusions can apply, such as a percentage exclusion on long-term capital gains from qualified sales.
Can I carry forward unused deductions or credits?
Oregon generally follows federal rules on the carryforward of net operating losses and unused credits, allowing you to apply these in subsequent years.
What records should I keep for tax purposes?
Keep comprehensive records of your income, deductions, and credits claimed. This includes W-2s, 1099s, receipts, and proof of payments for expenses.

The Oregon state income tax system, with its progressive rates and comprehensive deductions, can significantly impact individuals and businesses.
