Oregon Capital Gains Tax Rules
Oregon has no separate capital gains rate. Short-term and long-term gains are both taxed as ordinary income at Oregon's 2026 rates from 4.75% to 9.9%; the 9.9% rate applies above $125,000 of taxable income ($250,000 for joint filers). Oregon's federal tax subtraction and personal exemption credit phase out as income rises, so the tax added by a gain can be more than 9.9% of it. This state tax is separate from — and in addition to — the federal capital gains tax you owe to the IRS.
Understanding Oregon's capital gains rules is essential for investors, homeowners selling property, and business owners who plan to sell assets. The calculator above computes your estimated federal and Oregon state capital gains tax based on your sale price, cost basis, holding period, and income. It subtracts the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly, $24,150 head of household) from the income you enter, stacks the gain on top of your other income, and taxes each slice at its own rate.
Federal vs Oregon Capital Gains Tax
The federal tax on a gain depends on your taxable income and on how long you held the asset. For long-term gains (held more than 12 months), the 2026 federal rates set by IRS Rev. Proc. 2025-32 are 0% on taxable income up to $49,450 single / $98,900 married filing jointly / $66,200 head of household, 15% up to $545,500 single / $613,700 joint / $579,600 head of household, and 20% above those thresholds. The gain is stacked on top of your other income, so one sale can be taxed partly at 0%, partly at 15% and partly at 20%. Short-term gains are taxed as ordinary income at the 2026 federal brackets of 10% to 37%. A 3.8% Net Investment Income Tax is added on the lesser of the gain or the amount by which your modified adjusted gross income exceeds $200,000 (single or head of household) or $250,000 (married filing jointly).
Worked example (2026): a single filer with $90,000 of other income sells stock held for two years at a $50,000 gain. Federal tax is $7,500 (the whole gain falls in the 15% band) and Oregon tax is $5,369, a combined $12,869 or 25.7% of the gain. Sold after 11 months instead, the same gain is short-term: $11,364 federal plus $5,369 Oregon tax, $16,733 in total. The calculator above reproduces both results.
Oregon Has No Long-Term Capital Gains Preference — Portland Extras (2026)
Unlike the federal government, Oregon does NOT give a lower rate for long-term capital gains — every gain is taxed as ordinary income at up to 9.9% regardless of how long you held the asset. The 9.9% top bracket kicks in at $125,000 taxable income (single) / $250,000 (married joint) for 2026. For a single filer with $250,000 of other income, a long-term $100,000 gain owes: $15,000 federal (15%) + $9,900 Oregon + $3,800 NIIT = $28,700 total (28.7% effective). Multnomah County adds a 1% Preschool for All tax on high earners (income over $125k single / $200k joint) — capital gains count toward the base. Portland Metro adds a 1% Supportive Housing Services tax on the same brackets. A Portland-resident investor faces 9.9% state + 1% + 1% = 11.9% in Oregon-and-local income tax on gains.

Oregon Cap Gains Strategies & Exemptions
Several strategies can help Oregon taxpayers reduce their capital gains tax burden. First, hold assets for more than 12 months to qualify for the lower long-term federal rate. Second, harvest capital losses to offset gains — if you have losing positions, selling them in the same tax year can reduce your net taxable gain. Third, use tax-advantaged accounts (401k, IRA, HSA) to shelter future investment growth from both federal and Oregon state tax.
For Oregon homeowners, the federal home-sale exclusion allows you to exclude up to $250,000 (single) or $500,000 (married filing jointly) of gain from the sale of a primary residence, provided you meet the 2-of-5-year ownership and use tests. The calculator does not apply this exclusion, so enter only the gain that remains after it. Consult an Oregon tax professional to understand which exclusions apply to your specific situation.
Always work with a qualified tax professional before executing large asset sales. Tax laws change, and individual circumstances — such as installment sales, like-kind exchanges (1031 exchanges for real estate), or business asset sales — can significantly affect your total tax liability.

Frequently Asked Questions
What is the Oregon capital gains tax rate in 2026?
Oregon has no separate capital gains rate. In 2026 a gain is taxed as ordinary income at rates from 4.75% to 9.9% (the 9.9% rate applies above $125,000 of taxable income, $250,000 for joint filers), so the state tax depends on your total income. Because Oregon's federal tax subtraction and personal exemption credit phase out as income rises, the tax added by a gain can be more than 9.9% of it.
Does Oregon tax short-term vs long-term capital gains differently?
No. Oregon taxes short-term and long-term capital gains the same way, as ordinary income. Only the federal tax depends on the holding period: gains on assets held more than 12 months get the 0%, 15% or 20% long-term rates, while short-term gains are taxed at ordinary federal rates of 10% to 37%.
Are there Oregon capital gains exemptions?
Oregon has no general exclusion for capital gains — a gain is taxed as ordinary income. At the federal level you can exclude up to $250,000 of gain ($500,000 if married filing jointly) on the sale of your main home if you meet the ownership and use tests. Consult a tax professional for your specific situation.
How does Oregon capital gains compare to federal rates?
Federal long-term capital gains rates for 2026 are 0%, 15% and 20%: the 15% rate starts above $49,450 of taxable income for single filers ($98,900 married filing jointly) and the 20% rate above $545,500 ($613,700). Oregon state tax is charged in addition to the federal tax. For example, a single filer with $90,000 of other income and a $50,000 long-term gain owes $7,500 federal and $5,369 to Oregon.
Do I owe Oregon capital gains tax if I move before selling?
If you move before selling an asset, your state tax obligation depends on where you were a resident when the sale occurs. If you are a Oregon resident at the time of sale, Oregon capital gains rules apply. Always consult a tax advisor when changing states.
Does Oregon give a lower rate for long-term capital gains like the IRS does?
No. Oregon taxes long-term and short-term capital gains identically at ordinary-income rates up to 9.9%. This is unlike the federal system, where long-term gains held over 12 months get 0%, 15%, or 20% preferential rates. For a $100,000 long-term gain held 5+ years: the IRS may charge only 15%, but Oregon still charges up to 9.9% — as much as $9,900 of state tax for a filer in the top bracket. Only farm/forestry land held under specific rules and Working Family Household & Dependent Care Credit produce meaningful reductions.
Do Portland residents pay extra tax on capital gains beyond the 9.9% Oregon rate?
Yes. Portland-metro residents pay two local income taxes on top of the Oregon 9.9% rate: (1) Multnomah County's 1% Preschool for All tax on taxable income over $125,000 single / $200,000 joint, and (2) Portland Metro's 1% Supportive Housing Services tax on the same thresholds. Combined worst-case for a Portland investor: 9.9% Oregon + 1% Multnomah + 1% Metro = 11.9% on gains, plus federal 15-20% and NIIT 3.8%. Total peak rate near 35% for high earners.
