Best Tax Tips for Retirees in Oregon (2026)

This list is the practical companion to our full reference, Retirement and Social Security tax in Oregon, which covers what Oregon taxes, how Washington compares, and the move-across-the-river and Roth conversion questions. Here we stick to specific rules, figures and elections. Federal 2026 figures are from the IRS. Oregon figures are from the Oregon Department of Revenue’s Publication OR-17 for tax year 2025, the latest the department has published; check the 2026 edition when it is released.

1. Make sure Social Security comes back off your Oregon return

Oregon does not tax Social Security benefits. The mechanics matter, though: your Oregon return starts from federal figures, so any Social Security that is taxable federally has to be subtracted on the Oregon return. Publication OR-17 treats Railroad Retirement Board benefits the same way. If your Oregon taxable income looks too high, this is the first line to check.

2. Set Oregon withholding on pensions and IRA distributions

Publication OR-17 says most retirement income is subject to Oregon tax when an Oregon resident receives it, even if it was earned while living somewhere else. The Oregon Department of Revenue’s 2026 Form OR-W-4 instructions say the same form employees use is also how you set Oregon withholding on a pension, annuity or other periodic payment. Withholding at the source is often simpler than making quarterly estimated payments.

3. Claim the federal pension subtraction if you served before October 1991

Retired federal employees and their beneficiaries may be able to subtract part or all of their federal pension on the Oregon return. The subtraction depends on months of federal service (or points) before and after 1 October 1991:

• All service before 1 October 1991: subtract 100% of the taxable federal pension.
• No service before that date: no subtraction.
• Service on both sides: divide months before 1 October 1991 by total months. That percentage stays the same from year to year.
• Thrift Savings Plan withdrawals qualify once you are retired. Money moved out of the TSP into another account loses its federal pension character.

4. Test yourself for the Oregon retirement income credit

This credit is small and easy to overlook, and it is aimed at retirees with modest income and little Social Security. For tax year 2025, Publication OR-17 says you may qualify if you were 62 or older at the end of the year, had taxable retirement income, and:

• household income is less than $22,500 ($45,000 married filing jointly);
• Social Security and Tier 1 Railroad Retirement benefits are less than $7,500 ($15,000 married filing jointly); and
• household income plus those benefits is less than $22,500 ($45,000 married filing jointly).

The credit is 9% of a worksheet amount, cannot exceed your tax, and does not carry forward. Household income for this credit includes some items that are not in federal adjusted gross income, so it is worth running the worksheet rather than guessing.

5. Claim the new federal senior deduction, and know Oregon does not follow it

The One Big Beautiful Bill Act added a deduction of $6,000 for each person aged 65 or older, $12,000 for a married couple when both qualify, for tax years 2025 through 2028. According to the IRS, it is available whether you itemize or take the standard deduction, it is in addition to the existing extra standard deduction for age 65, and:

• it phases out for modified adjusted gross income over $75,000 ($150,000 for joint filers);
• married couples must file jointly to claim it; and
• the Social Security number of each qualifying person must be on the return.

Oregon is a different story. For tax year 2025, Publication OR-17 lists the IRC Section 151 deduction for personal exemptions, which it says includes the deduction for taxpayers who are age 65 or older, among the federal provisions Oregon is disconnected from, so it does not reduce your Oregon tax. That is not true of every new federal deduction: Oregon does allow the tip, overtime and car loan interest deductions as subtractions on the Oregon return.

6. Use both age-based standard deductions

Separately from the senior deduction, both returns give older filers a larger standard deduction. For tax year 2026, the federal additional standard deduction for age 65 or older (or blind) is $1,650, or $2,050 if you are unmarried and not a surviving spouse (Rev. Proc. 2025-32). On the Oregon return for tax year 2025, the addition is $1,000 per box checked if married or a qualifying surviving spouse and $1,200 if single or head of household.

7. Take your first RMD on time, and decide about the double year

The IRS says required minimum distributions from traditional IRAs, SEP and SIMPLE IRAs and workplace plans generally start at age 73. Roth IRAs have no RMDs while the owner is alive.

• The first RMD can wait until 1 April of the year after you turn 73.
• Waiting means two RMDs in one year: the delayed first one and the second, due by 31 December. Two distributions in one year can raise your tax bracket.
• A missed RMD can carry a 25% excise tax on the amount not taken, reduced to 10% if corrected within two years.

8. Give to charity straight from your IRA

From age 70½, you can have an IRA pay a qualified charity directly. The IRS calls this a qualified charitable distribution (QCD). It is left out of your taxable income, and it can count toward all or part of your RMD. For 2026 the limit is $111,000 per person (IRS Notice 2025-67). The distribution has to go from the IRA to the charity: money you withdraw and then donate does not qualify. Because a QCD keeps the income off the return, it can matter even to people who take the standard deduction.

9. Check the special Oregon medical subtraction at 66

Oregon has its own subtraction for medical and dental expenses of taxpayers who turned 66 by the end of the year. For tax year 2025, Publication OR-17 limits it to federal AGI of $200,000 or less ($100,000 if single or married filing separately), and caps it at $1,800 per qualifying person at the lowest incomes, stepping down to $1,000 in the top band. Expenses for anyone under 66, and for dependents, do not count, and neither do expenses deducted elsewhere on the return. Keep the medical and dental receipts for each spouse separately.
