Oregon for retirees: Social Security untaxed, everything else taxed in full

Oregon draws one bright line through retirement income. Social Security and Tier 1 Railroad Retirement benefits come off the return in full, on line 11 of Form OR-40, at any age and any income. Everything else a retiree draws is taxed as ordinary income: a company pension, Oregon PERS, a federal or military pension for service after September 1991, traditional IRA and 401(k) withdrawals, required minimum distributions, the taxable part of an annuity, and the full amount of a Roth conversion. The rates reach 8.75% at about $22,800 of taxable income on a joint return for 2026, so a couple with $50,000 of pension and IRA income pays 8.75% on most of it. There is no general retirement-income exclusion and no age-based exclusion. What Oregon offers instead is the Social Security subtraction, an extra $1,000 per spouse on the standard deduction at 65 (verify), a special medical subtraction at 66, a retirement income credit that almost nobody qualifies for, and the federal tax subtraction, which helps retirees exactly as much as it helps everyone else.

The practical result is that where your retirement money comes from matters more in Oregon than in many places. Two retirees with the same $70,000 of income can owe very different amounts depending on how much of it is Social Security.

What is subtracted and what is taxed

The Social Security subtraction is of the amount on federal line 6b. If the federal formula taxes 85% of your benefit, 85% is in AGI and 85% comes off; the Oregon result is zero either way.

The federal pension rule. Oregon once exempted all federal pensions while taxing PERS. The courts ended that in the early 1990s, and the compromise that survives is a subtraction for the share of a federal pension earned by service before October 1, 1991. A civil servant or service member who retired with twenty years, eight of them before that date, subtracts 40% of the pension. Someone who enlisted in 1995 subtracts nothing. The Department’s veterans publication puts the test as a question: is the pension based on federal employment before October 1, 1991? If yes, work out the months.

The retirement income credit. At 62 or older you may claim a credit of 9% of your pension income, but the pension income that counts is capped at $7,500 single or $15,000 joint, and that cap is reduced dollar for dollar by Social Security received and by household income over $15,000 single or $30,000 joint. The credit is therefore zero once household income reaches $22,500 or $45,000, and household income here means almost everything except Social Security. A couple with $20,000 of Social Security and $30,000 of pension has a base of $15,000 less $20,000 less $0: nothing. The credit was written to expire for tax years beginning in 2026; the 2025 legislature’s omnibus bill, HB 2087, extends it to 2032. Few retirees will notice either way.

The federal senior deduction, and why it stops at the state line

The $6,000 federal deduction for taxpayers 65 and older, in effect for 2025 through 2028, lives in section 151 of the Internal Revenue Code. Oregon is disconnected from section 151; the Department’s guide lists the senior deduction specifically as a conformity exception. Form OR-40 starts from AGI, so the deduction never enters the Oregon computation and no add-back is needed. The same is true of the extra federal standard deduction for age.

Oregon’s own age breaks are smaller and arrive in two places. On line 17 the standard deduction grows by $1,200 for a single or head-of-household filer and $1,000 per spouse on a joint return for each person 65 or older, and again for blindness (2025 figures; 2026 to come). On Schedule OR-ASC, code 351, a taxpayer or spouse who turned 66 by year end may subtract medical and dental expenses paid for themselves, up to $1,800 per qualifying person when AGI is under $50,000 joint ($25,000 single), $1,400 up to $100,000 ($50,000), $1,000 up to $200,000 ($100,000), and nothing above that. The expenses must be ones you could have itemized; Medicare premiums and supplemental insurance count. It is a modest amount, but it comes on top of itemizing the same expenses on Schedule OR-A if you itemize.

Itemizing in retirement

Oregon lets you itemize on Schedule OR-A even when you took the federal standard deduction, and retirees are the group this helps most. Medical and dental expenses above 7.5% of AGI, property tax, mortgage interest and charitable gifts all count. A couple with $86,600 of AGI, $12,000 of medical costs including Medicare and Medigap premiums, $4,500 of property tax and $3,000 of charitable giving has $5,505 of medical over the floor plus $7,500 of other deductions: $13,005 against a standard deduction of $7,820. Federally the $32,200 standard deduction wins without a contest; in Oregon, the itemized total wins by more than $5,000. Keep the receipts.

Roth conversions: expensive here

A Roth conversion moves money from a traditional IRA to a Roth and is taxed as income in the year of the move. In Oregon the converted amount sits in AGI and nothing takes it back out, so it is taxed at the full graduated rates, mostly 8.75% and, above $125,000 single or $250,000 joint of taxable income, 9.9%. The federal tax subtraction softens the blow a little, because a conversion raises your federal tax, and more federal tax means a larger Oregon subtraction, but the subtraction is capped at $8,500, and a conversion of any size pushes a typical retiree past the cap. Beyond that point, every converted dollar is taxed at the Oregon marginal rate with no offset. A conversion that also lifts AGI past $200,000 joint costs the exemption credits too.

The arithmetic suggests two things. Convert in the years before you move to Oregon, if you have that choice, or in a low-income year such as the gap between retiring and starting Social Security. And convert in slices sized to stay under the 9.9% line and the $200,000 exemption-credit cliff. The federal considerations, including what a conversion does to Medicare premiums two years later, are in Roth IRAs and the backdoor Roth and IRMAA.

The flip side is that the qualified charitable distribution is worth more in Oregon than in most places. A QCD sends up to $111,000 for 2026 ($108,000 for 2025) (verify) a year from an IRA directly to charity, satisfies the required minimum distribution, and never enters AGI, so it escapes both federal tax and Oregon tax at 8.75% or 9.9%. For a retiree over 70½ who gives to charity anyway, the QCD beats writing a check and itemizing on Schedule OR-A. See RMDs and giving from your IRA.

Withholding on retirement income

Nobody withholds Oregon tax from Social Security, and most pension and IRA payers withhold state tax only if asked. PERS and many large plans will withhold Oregon tax on request; a brokerage IRA often will not. A retired couple whose only withholding is federal can easily owe $2,000 or $3,000 to Oregon in April and then owe underpayment interest on top, because estimated payments are required once you expect to owe $1,000 or more after withholding and credits. Ask each payer for Oregon withholding, or make four estimated payments by April 15, June 15, September 15 and January 15. The federal rules are the same shape; see Estimated payments.

Property tax: a deferral, not an exemption

Oregon has no homestead exemption, no senior freeze and no property-tax credit on the income tax return. Measure 50 limits the growth in every property’s assessed value to 3% a year, for everyone, and that is the state’s main property-tax protection. The one program for seniors is the Senior and Disabled Property Tax Deferral, run by the Department of Revenue through the county assessors.

The deferral is a loan, not a gift. It suits a homeowner who is house-rich and income-poor and intends to stay. It is a poor fit for someone planning to sell within a few years, because the taxes, interest and lien costs come out of the sale.

Disabled veterans and their surviving spouses may claim a partial exemption of assessed value through the county assessor (verify). There is no general veterans’ or seniors’ exemption otherwise.

Moving in, moving out

Federal law bars a state from taxing the retirement income of someone who no longer lives there, so a pension earned elsewhere and paid to a new Oregon resident is Oregon’s to tax, and Oregon taxes it. The Department says so on its own page: once you move here, retirement income is taxable here, apart from Social Security and the pre-1991 federal pension share. A retiree leaving Oregon stops owing Oregon tax on pension and IRA income the day residency ends, which is one reason the move date matters and why the Department looks hard at it. In the move year, Form OR-40-P allocates each pension and IRA payment to the state you lived in when you received it. Details, including how Oregon tests residency, are in Moving to Oregon.

The estate tax

Oregon’s estate tax begins at $1,000,000 of gross estate, a threshold that has not changed since 2012, with rates from 10% to 16% and no portability between spouses. A couple who own a paid-off Portland house and a modest IRA can cross it. Form OR-706 is due twelve months after death. The 2026 legislature declined to raise the threshold, and a repeal initiative did not reach the November ballot. For a retiree, the tax is a reason to look at the usual federal tools, lifetime gifts and a credit-shelter trust, at a far lower level of wealth than the federal estate tax would require.
