Oregon does not tax Social Security benefits. Under ORS 316.054, any Social Security or Tier 1 railroad retirement income that shows up in your federal adjusted gross income gets subtracted before Oregon calculates your state tax, no matter how much you earn or how large your monthly check is.1Oregon State Legislature. Oregon Revised Statute Chapter 316 – Personal Income Tax The exemption is complete, but it applies only to your Oregon return, and most other retirement income you receive is still taxable at the state level.
How the Subtraction Works on Your Return
Oregon starts its tax calculation from your federal adjusted gross income. If part of your Social Security is taxable federally, that amount initially rides into your Oregon calculation along with everything else. The state then requires you to subtract it back out. You report that subtraction on Schedule OR-ASC, or Schedule OR-ASC-NP if you’re a part-year resident or nonresident.2Oregon Department of Revenue. Publication OR-17, Oregon Individual Income Tax Guide
It’s a straightforward step, but not an automatic one. If you file your own return and skip the schedule, you’ll pay Oregon tax on Social Security you didn’t owe. Tax software handles it if you enter the benefit correctly; a paper filer needs to remember the form.
Federal Tax on Social Security Still Applies
Oregon’s exemption removes Social Security from your state calculation only. The IRS may still tax a portion of your benefits based on your “combined income,” which is your adjusted gross income plus nontaxable interest plus half your Social Security.
For single filers, combined income between $25,000 and $34,000 makes up to 50% of benefits taxable. Above $34,000, up to 85% can be taxed. For joint filers, the thresholds are $32,000 and $44,000.3IRS. IRS Reminds Taxpayers Their Social Security Benefits May Be Taxable Those numbers have never been adjusted for inflation, so more retirees cross them each year. If you have a pension, investment income, or part-time wages alongside Social Security, the federal bill can still be real money even when Oregon takes nothing.
What Oregon Does Tax
Most other retirement income is fully taxable in Oregon. Distributions from pensions, 401(k) plans, traditional IRAs, and deferred compensation plans are all taxed at Oregon’s regular income tax rates, which range from 4.75% to 9.9%.4Oregon Department of Revenue. Personal Income Tax The state has no sales tax, so income tax carries more of the load, and retirement withdrawals are treated like any other income.
Oregon PERS benefits fall into this same bucket. PERS pension payments, OPSRP pension payments, and Individual Account Program distributions all have Oregon income tax withheld by default while you remain a resident. If you move out of Oregon after retiring, you can opt out of the withholding.
The Federal Pre-October 1991 Carve-Out
One narrow exception matters for federal retirees. If you receive a federal government pension and some of your service occurred before October 1, 1991, you can subtract the portion of your pension attributable to that earlier service. The math is a simple ratio: total pension income for the year multiplied by pre-October 1991 months of federal service divided by total months of federal service.1Oregon State Legislature. Oregon Revised Statute Chapter 316 – Personal Income Tax Someone with 20 years of federal service, half of it before October 1991, could subtract roughly half the pension from Oregon tax.
The Retirement Income Credit for Age 62 and Older
Oregon offers a tax credit aimed at retirees age 62 or older who receive taxable retirement income. The credit is 9% of the lesser of your total retirement income or a base amount that shrinks as your Social Security and household income rise.5Cornell Law School. Oregon Admin Code 150-316-0225 – Retirement Income Credit
The base amount starts at $15,000 for joint filers and $7,500 for everyone else. It’s reduced dollar-for-dollar by your Social Security benefits, and reduced further by household income above $30,000 (joint) or $15,000 (other). Social Security itself doesn’t count toward that household income figure. The credit phases out at higher income levels, so it mainly helps retirees with modest incomes who are drawing on both Social Security and a pension or retirement account.
Do Oregon Seniors Still Need to File?
Even with Social Security exempt, you may still need to file an Oregon return if your other income clears the filing threshold. For tax year 2025, a single filer age 65 or older must file if gross income exceeds $9,135. For joint filers where one spouse is 65 or older, the threshold is $16,865, and it rises to $17,865 when both spouses are 65 or older.6Oregon Department of Revenue. Do I Need to File? The 2026 thresholds hadn’t been published at the time of writing but typically move modestly each year.
One quirk to know: Social Security benefits that are exempt from Oregon tax still count as gross income for the purpose of deciding whether you need to file. If you’re close to the threshold, run the numbers. And even if you don’t technically owe anything, filing can still be worthwhile if you’re eligible for the retirement income credit or another refundable credit.
