Oregon does not tax long-term gains at a lower rate. A gain from stocks, a business or real estate flows into your income through your federal return, and Oregon taxes the total on its four-bracket rate schedule. Three points are worth knowing: the top rate of 9.9% starts at $125,000 of taxable income for a single filer, there is a separate reduced rate for gains from selling a farming business, and a 2026 law changed Oregon's treatment of small business stock gains.
This guide uses the Oregon Department of Revenue's 2025 Publication OR-17 (revised 29 January 2026), its 2025 instructions for Forms OR-40, OR-40-N and OR-40-P and its qualified business income page, its 2026 Publication OR-ESTIMATE, a June 2026 Business Oregon summary of new laws, and two IRS pages, all read on 3 November 2026. We could not read the Oregon Revised Statutes or the 2026 rate tables, so the full return brackets below are the 2025 figures. The Department's 2026 estimated-tax publication does list 2026 rate charts, which we show in the rate section, and every rule is stated as the Department states it.
The Department's Form OR-40 instructions tell full-year residents to enter federal adjusted gross income from Form 1040 on line 7. A capital gain reported on your federal return is therefore already in your starting figure, and Oregon taxes it with the rest of your income. Neither Publication OR-17 nor the OR-40 instructions describe a general lower rate or holding-period rule for gains; the rate charts apply to taxable income as a whole.
The federal system works differently. IRS Topic 409 says that if you have a net capital gain, a lower tax rate may apply to the gain than the rate that applies to your ordinary income, that you generally have a long-term gain if you hold the asset more than one year, and that net short-term gains are taxed as ordinary income at graduated rates. Oregon's return does not copy that split. The exceptions we found are the farm rate below and the small business stock change for 2026.
Publication OR-17 lists marginal rates for tax years 2022 to 2025. The 2025 figures for a single filer (the same brackets apply to married filing separately) are 4.75% on the first $4,400 of taxable income, 6.75% from $4,401 to $11,100, 8.75% from $11,101 to $125,000 and 9.9% over $125,000. For married filing jointly the 2025 brackets begin with 4.75% on the first $8,800, and the 9.9% rate applies over $250,000. Head of household and qualifying surviving spouse use the same thresholds as married filing jointly (the same table row).
The 2025 Form OR-40 instructions give the tax rate charts for taxable income of $50,000 or more. Chart S (single or married filing separately) is $4,065 plus 8.75% of the excess over $50,000 up to $125,000, then $10,627 plus 9.9% of the excess over $125,000. Chart J (joint, head of household or qualifying surviving spouse) is $3,756 plus 8.75% of the excess over $50,000 up to $250,000, then $21,256 plus 9.9% of the excess over $250,000.
For 2026, the Department's Publication OR-ESTIMATE (revised 7 October 2025) gives rate charts for estimating 2026 tax. For single and married filing separately they are 4.75% on taxable income up to $4,550, $216 plus 6.75% of the excess over $4,550 up to $11,400, $678 plus 8.75% of the excess over $11,400 up to $125,000, and $10,618 plus 9.9% of the excess over $125,000. For married filing jointly, head of household and qualifying surviving spouse they are 4.75% up to $9,100, $432 plus 6.75% of the excess over $9,100 up to $22,800, $1,357 plus 8.75% of the excess over $22,800 up to $250,000, and $21,237 plus 9.9% of the excess over $250,000. The 8.75% and 9.9% rates and the $125,000 and $250,000 thresholds are unchanged from 2025. These are estimating charts, not the 2026 return instructions, which we could not find published, so confirm against those before filing.
This table is our arithmetic, not an official calculation. It uses the 2025 single-filer brackets above and shows how much Oregon tax a $50,000 gain adds when it sits on top of other Oregon taxable income (after deductions, before credits). The extra tax depends on where the gain lands in the brackets, not on how long you held the asset.
| Other Oregon taxable income | Tax without the gain | Tax with a $50,000 gain | Tax added by the gain |
|---|---|---|---|
| $30,000 | $2,315 | $6,690 | $4,375 |
| $60,000 | $4,940 | $9,315 | $4,375 |
| $130,000 | $11,122 | $16,072 | $4,950 |
In the first two rows the whole gain falls in the 8.75% bracket (8.75% of $50,000 is $4,375). In the last row the filer is already above $125,000, so the gain is taxed at 9.9% ($4,950). The Department's tax tables for taxable income under $50,000 give tax by income range, so the first row of a printed table can differ from this bracket arithmetic by a few dollars. Real returns also depend on credits, exemptions, the federal tax subtraction and other items, so use this only to see the shape of the tax.
The OR-40-N and OR-40-P instructions say Oregon taxes full-year residents on income from all sources. Part-year residents are taxed on income from all sources earned or received while an Oregon resident, plus income from Oregon sources while a nonresident. Nonresidents are taxed only on income from Oregon sources, and the same instructions list the sale of Oregon property among Oregon sources.
Publication OR-17 says that for a nonresident Oregon taxes the gain (or allows the loss) from Oregon sources. We did not find a sentence there or in the instructions stating how a nonresident's gain on stock or other intangibles is sourced, so we do not state a rule for it; ask the Department or a preparer.
When a nonresident sells Oregon real property, Publication OR-17 says authorized escrow agents may be required to withhold taxes due. Unless an exception applies, once escrow closes the agent must withhold and remit the least of four percent of the consideration, the net proceeds from the sale, or eight percent of the gain includible in Oregon taxable income. The nonresident uses Form OR-18-WC to calculate the gain or claim an exemption from withholding.
Publication OR-17 says that generally Oregon will tax the gain from the sale of your residence only when the federal government taxes it, and that Oregon won't tax any gain excluded on your federal return. IRS Topic 701 says you may qualify to exclude up to $250,000 of the gain on the sale of your main home, or up to $500,000 if you file a joint return with your spouse. Only the gain above the federal exclusion would normally reach your Oregon return, taxed at the brackets above. For the federal tests, see our home sale capital gains guide.
Farm sales. Publication OR-17 describes a farm liquidation long-term capital gain rate: if you sold or exchanged capital assets used in farming activities during the tax year, you may be able to apply a reduced tax rate to your net long-term capital gain. The sale or exchange must end all of your ownership interests in a farming business or in property used in a farming business, and you may not claim it on a sale to a related person under IRC Section 267. You compute the tax with Publication OR-FCG. We did not read the reduced rate itself in the sources we could open, so we do not state it here.
Qualifying business income. The Department's QBIRTR page says that if you have qualifying business income from a sole proprietorship, a partnership or an S corporation, you may elect to calculate your Oregon tax using a reduced rate for that income. The page says qualifying income does not include the wages of the business owner or the interest, dividends or capital gains of the business, so this rate is not a way to reduce tax on selling an investment.
Capital losses. Publication OR-17 limits net losses to $3,000 ($1,500 if married filing separately) for full-year residents, part-year residents and nonresidents.
A June 2026 Business Oregon summary of new laws says Senate Bill 1507 (Oregon Laws 2026, chapter 142) disconnects certain state tax provisions from the federal tax code, most notably bonus depreciation and favorable treatment of capital gain from small business stock. The bill summary in the same document says it disconnects from, and requires addback of amounts for, federal provisions allowing the exclusion of gain from small business stock, and applies to tax years beginning on or after January 1, 2026. If you expect to claim the federal small business stock exclusion, ask the Department or a preparer how the 2026 Oregon rules apply to you. We found no 2026 change to the rates in the sources we could read (the 2026 estimating charts above keep the same four rates), but we could not open the Oregon Legislature's own site, so check it for the bill text and anything newer.
