Updated October 5, 2026. Quick answer: No, for a full-year resident. The Department of Revenue’s Publication OR-17 says of the HSA deduction that “flows through to your Oregon return via your federal AGI” and that you should not “claim an additional deduction on your Oregon return”. The 2026 federal HSA limits are $4,400 for self-only coverage and $8,750 for family coverage.

What the Oregon documents say
Publication OR-17, the Oregon Individual Income Tax Guide for 2025, lists the HSA deduction among its adjustments as “[Adjustment code 003]”. It says you may take the federal deduction if you made contributions to an HSA during 2025, and sends the reader to the federal Form 8889 instructions and IRS Publication 969.
For a full-year resident, the guide says “flows through to your Oregon return via your federal AGI”. For a part-year resident, the Oregon deduction combines the contributions made while an Oregon resident with a partial deduction for contributions made as a nonresident who had Oregon-source income.
Earnings, distributions and the rest
Part-year residents and nonresidents use a formula in the guide to find the Oregon share. The guide’s adjustment section is also where it says “Oregon allows a partial deduction” for a nonresident in other adjustment categories, so this page relies only on the HSA paragraph for the HSA rule. The documents read do not address HSA earnings or distributions.
A worked example at the 2026 family limit
An illustration, not a return: a full-year Oregon resident with family coverage who makes the 2026 federal family limit of $8,750 as a deductible contribution takes the federal deduction once, on the federal return. It reaches Oregon through federal AGI, and the guide says not to claim it again. That is $4,350 more than the self-only limit of $4,400 would allow.
What a mover should know
Every figure on this page is Oregon’s own rule. If you moved during the year, or live in one state and work in another, check each state’s page and return, because the documents read here describe only Oregon and none of them settles a part-year or two-state case. The federal side is the same everywhere: see CMG’s 2026 HSA contribution limits page, and state tax on HSA contributions for the other states checked.
What the documents do not say
- The guide read is for tax year 2025. It does not state a rule for HSA earnings or distributions, and no Oregon statute is cited.
Common mistakes
- Claiming a second HSA deduction on the Oregon return as a full-year resident; the guide says the federal deduction already flows through.
- Applying the full-year rule to a part-year or nonresident year; the guide gives a formula for those filers.
- Assuming the answer for one state applies to another, or that the state answer changes the federal limits.
