Does Oklahoma have a capital gains tax?
Oklahoma capital gains tax is part of the regular income tax: gains are added to your other income and taxed at rates up to 4.5% for 2026. House Bill 2764, signed by Governor Kevin Stitt in May 2025, cut the top rate from 4.75% to 4.5% starting with tax year 2026 and folded six brackets into three.
The rate matters less than the deduction for most building owners. The Oklahoma Tax Commission lets you deduct qualifying gains from the sale of real property located in Oklahoma that you owned for at least five uninterrupted years before the sale. A long-held apartment building in Oklahoma City or Tulsa usually meets that test, which can take most of the gain off the Oklahoma return.
Oklahoma income tax rates for 2026
Oklahoma has a zero band and three rates for 2026: 2.5%, 3.5% and 4.5%. The Oklahoma Tax Commission’s 2026 withholding tables, which build in the standard deduction, apply 4.5% to annual wages above $13,550 for a single filer and $27,100 for a married filer. In practice, any building gain that is still taxable lands in the 4.5% bracket.
HB 2764 also sets up future cuts. Each December the State Board of Equalization checks whether revenue grew enough to pay for another quarter-point reduction, and a cut that is triggered takes effect two tax years later. A declared revenue failure cancels it. If you plan to sell in 2027 or 2028, ask your preparer whether a trigger has been certified.
| Rate (2026 withholding table, annual wages) | Single | Married |
|---|---|---|
| 0% | Up to $10,100 | Up to $20,200 |
| 2.5% | $10,100 to $11,250 | $20,200 to $22,500 |
| 3.5% | $11,250 to $13,550 | $22,500 to $27,100 |
| 4.5% | Over $13,550 | Over $27,100 |
The Oklahoma capital gain deduction for real estate
Oklahoma lets you deduct qualifying gains that receive capital gain treatment and are included in federal income. The 2026 Form 561 for residents (Form 561NR for nonresidents and part-year residents) lists the categories. The one that matters for property owners covers the sale of real or tangible personal property located within Oklahoma that has been owned for at least five uninterrupted years before the sale.
Three conditions do the work. The property has to be in Oklahoma, so a Tulsa owner who sells a building in Fort Smith gets nothing from this rule. The five years have to be uninterrupted. And the gain has to be net capital gain as defined in Section 1222(11) of the Internal Revenue Code, which means the deduction follows how your federal return labels the income.
Buildings held through a partnership or LLC can qualify too. Form 561 requires that the entity held the asset for the full period and that you were a member for an uninterrupted period of the same length. If you joined the partnership two years ago, your share of the gain may not qualify even though the entity has owned the building for a decade.
What stays taxable when you sell an Oklahoma rental
Even when the building meets the five-year test, some income from the sale can still be taxed at Oklahoma rates.
- Section 1245 recapture on appliances, carpet, cabinets and other personal property, often from a cost segregation study. It is ordinary income on Form 4797, not net capital gain, so it does not fit the Form 561 definition. The Tax Commission has not addressed recapture directly, so plan on it being taxed at up to 4.5%.
- All of the gain on a building owned less than five uninterrupted years.
- Gain on property outside Oklahoma. An Oklahoma resident pays Oklahoma tax on it, subject to any credit for tax paid to the other state.
- Interest on a seller-financed note, and rent or other income you earn in the year of sale.
How Oklahoma tax stacks on federal tax
Federal tax is the larger part of the bill for nearly every Oklahoma seller. For 2026, IRS Revenue Procedure 2025-32 puts the 20% long-term capital gains rate on taxable income above $613,700 for married couples filing jointly and $545,500 for single filers, with 0% up to $98,900 joint and 15% in between.
Straight-line depreciation on the building comes back as unrecaptured Section 1250 gain, taxed federally at up to 25%. It is still part of net capital gain, so it fits the Oklahoma deduction when the holding test is met. Section 1245 recapture is taxed federally at ordinary rates up to 37% and in Oklahoma at up to 4.5%. The 3.8% net investment income tax applies once modified adjusted gross income passes $250,000 joint or $200,000 single.
| Part of the gain | Federal rate (2026) | Oklahoma, held 5+ years | Oklahoma, held less than 5 years |
|---|---|---|---|
| Appreciation above original cost | 0%, 15% or 20% | Deductible | Up to 4.5% |
| Straight-line depreciation (unrecaptured 1250 gain) | Up to 25% | Deductible | Up to 4.5% |
| Section 1245 recapture | Ordinary rates up to 37% | Up to 4.5% | Up to 4.5% |
| Net investment income tax | 3.8% above the thresholds | None | None |
Nonresidents selling Oklahoma property
A nonresident who sells an Oklahoma building reports the gain on an Oklahoma nonresident return, and the capital gain deduction is available through Form 561NR. For gain that passes through a partnership to a nonresident partner, the Form 561-P instructions say only the portion allocated or apportioned to Oklahoma is entered.
A Texas or Arkansas owner of a building in Lawton or Stillwater can therefore owe little Oklahoma tax on a long-held property, apart from any Section 1245 recapture. Ask your title company early whether any state paperwork applies at closing. Foreign sellers also face federal FIRPTA withholding, which is a separate federal rule.
Worked example: selling a $2 million apartment building in Oklahoma
A married couple in Edmond sells a 24-unit building in Oklahoma City for $2,000,000 in 2026. They bought it in 2012 for $1,100,000. Selling costs are $90,000, so the amount realized is $1,910,000. They have taken $420,000 of depreciation, $370,000 straight-line on the building and $50,000 on personal property, so adjusted basis is $680,000 and the gain is $1,230,000. Their other taxable income is $420,000.
Federal tax: the $50,000 of Section 1245 recapture falls in the 32% bracket, or $16,000. The $370,000 of unrecaptured Section 1250 gain is taxed at 25%, or $92,500. The remaining $810,000 of gain sits above the $613,700 threshold and is taxed at 20%, or $162,000. The 3.8% net investment income tax on the full gain adds $46,740. Federal tax is $317,240.
Oklahoma tax: they owned the building for well over five uninterrupted years, so the $1,180,000 of net capital gain is deducted on Form 561. Only the $50,000 of recapture stays in Oklahoma income, and at 4.5% that is $2,250. Had they owned it less than five years, the full $1,230,000 would be taxed, about $55,350. Waiting out the holding period is worth roughly $53,100 here.
Their total bill is about $319,490, close to 16.7% of the amount realized. The capital gains tax calculator runs the federal side on your own numbers.

How a 1031 exchange changes the picture in Oklahoma
A 1031 exchange defers the federal tax, which is where the money is for a long-held Oklahoma building. Oklahoma taxable income starts from federal adjusted gross income, so gain deferred federally never shows up on the Oklahoma return either.
In the example, a full exchange into a replacement of $2,000,000 or more defers the $317,240 of federal tax and the $2,250 of Oklahoma tax on recapture. Any cash you keep or debt you are relieved of without replacing is boot, and it is taxed federally in the year of the exchange.
One Oklahoma wrinkle deserves a conversation with your CPA. The deduction applies only to property located in Oklahoma. If you exchange into a building in Texas and later sell it while you still live in Oklahoma, that later gain is on out-of-state property and does not fit the Oklahoma-property category, even though the original building would have. Our guide to the 1031 exchange in Oklahoma covers this and the deadlines.
Installment sales and seller financing in Oklahoma
An installment sale spreads the federal gain over the years you collect principal, and each year’s gain shows up on that year’s federal return. The Oklahoma deduction is claimed on the return for the year the gain is reported, so the holding test is measured at the original sale date and a building you owned five uninterrupted years before closing should keep qualifying as payments arrive. Confirm that reading with your preparer.
The interest the buyer pays you on the note is ordinary income, so Oklahoma taxes it at up to 4.5%. Section 1245 recapture is reported in full in the year of sale no matter how payments are spread, which makes the first year heavier than most owners expect.
Ways to keep the Oklahoma share low
Most Oklahoma planning comes down to the holding period and the label on each piece of the gain.
- Check the date you, and any entity you own through, acquired the building. A sale one month short of five uninterrupted years can cost the full 4.5% on the gain.
- Ask your preparer for a recapture schedule before you agree on a price allocation; personal property allocations raise Section 1245 recapture.
- If you joined a partnership late, confirm your own membership period meets the Form 561 test.
- Keep federal planning first. An exchange, a Delaware statutory trust or an installment sale changes far more tax than any Oklahoma step.

For the tax a buyer will carry after closing, see property tax rate in Oklahoma. For tenant rules that come with the building, see Oklahoma landlord-tenant law for apartment owners.
Selling? Spread the tax with seller-carry terms
If a large tax bill is what is keeping you from selling, an installment sale may help. When you carry part of the price as a note, the gain is generally reported as you receive payments instead of all in the year of sale. Some parts of the gain, such as certain depreciation recapture, can still be due up front, so run the numbers with your CPA first.
Skyline Capital Investments buys apartment buildings with five or more units and can offer seller-carry terms, or a delayed closing that fits your 1031 timeline.
