The South Dakota capital gains tax rate is zero. The state has no personal income tax, so profits from selling stocks, bonds, real estate, or a business are not taxed at the state level.1South Dakota Department of Revenue. Taxes You still owe federal capital gains tax, and that is the only tax most South Dakota residents need to plan around when they sell an appreciated asset.
No State Tax, and It’s Unlikely to Change
South Dakota has never enacted a personal income tax. The Legislature has constitutional authority to impose one under Article XI, Section 2, but it has not done so. Voters added a second lock in 1996: Article XI, Section 14 requires either a two-thirds vote of both legislative chambers or a direct public initiative to impose any new state tax.2South Dakota Legislature. South Dakota Constitution Article XI That makes the zero rate about as stable as any tax policy gets short of a constitutional ban.
Federal Long-Term Capital Gains Rates for 2026
If you hold an asset for more than one year before selling, the profit is a long-term capital gain and is taxed at preferential federal rates rather than ordinary income rates.3Internal Revenue Service. Topic No. 409, Capital Gains and Losses For tax year 2026, the rate depends on your taxable income and filing status:
- 0% for single filers with taxable income up to $49,450, married filing jointly up to $98,900, or head of household up to $66,200.
- 15% for single filers from $49,450 to $545,500, married filing jointly from $98,900 to $613,700, or head of household from $66,200 to $579,600.
- 20% for taxable income above those upper thresholds.
The brackets adjust for inflation each year. The 0% rate is worth planning around if you have a lower-income year, because even a sizable gain can fall entirely within it when other taxable income is modest after deductions.3Internal Revenue Service. Topic No. 409, Capital Gains and Losses
Short-Term Gains Are Taxed as Ordinary Income
Hold an asset for one year or less and the IRS taxes the gain at your regular income tax rates. For 2026, the single-filer brackets run:
- 10% up to $12,400
- 12% from $12,401 to $50,400
- 22% from $50,401 to $105,700
- 24% from $105,701 to $201,775
- 32% from $201,776 to $256,225
- 35% from $256,226 to $640,600
- 37% above $640,600
A short-term gain can cost roughly twice what the same gain would owe as a long-term gain if it pushes you into a higher bracket.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If you are close to the one-year mark, waiting a few extra days before selling can save thousands. South Dakota charges nothing regardless of how long you held the asset, so this calculation is purely federal.
The 3.8% Net Investment Income Tax
Higher earners pay an additional 3.8% surtax on net investment income under the Affordable Care Act. It kicks in when your modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly.5Internal Revenue Service. Net Investment Income Tax It applies to capital gains, dividends, rental income, and other investment returns, and the tax is calculated on the lesser of your net investment income or the amount by which your modified AGI exceeds the threshold.6Internal Revenue Service. Questions and Answers on the Net Investment Income Tax
These thresholds are not indexed for inflation, so more taxpayers cross them each year. A South Dakota resident selling a rental property for a $300,000 gain could owe the 15% or 20% capital gains rate plus the 3.8% surtax, pushing the effective federal rate on part of the gain to nearly 24%.
Selling Your Home
If you sell your primary residence, you can exclude up to $250,000 of gain from federal tax, or $500,000 for a married couple filing jointly. You must have owned the home and used it as your primary residence for at least two of the five years before the sale.7Office of the Law Revision Counsel. 26 U.S. Code 121 – Exclusion of Gain from Sale of Principal Residence For married couples, only one spouse needs to meet the ownership test, but both must meet the two-year use test, and you cannot have claimed the exclusion on another home sale in the previous two years.
If you sell early because of a job relocation, health reasons, or certain unforeseen circumstances, you may qualify for a partial exclusion proportional to the time you lived there. Between the federal exclusion and South Dakota’s zero rate, most homeowners here owe nothing on a home sale. A married couple selling with $400,000 of appreciation would pay $0 at either level.
Inherited Property Gets a Step-Up in Basis
When you inherit property, your tax basis is generally stepped up to the fair market value on the date of the prior owner’s death.8Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired from a Decedent If a parent bought stock for $20,000 decades ago and it was worth $200,000 at death, your basis is $200,000. Selling right away produces no taxable gain.
This hits especially hard in South Dakota. The state has no income tax, no estate tax, and no inheritance tax, so an heir who sells shortly after inheriting may owe nothing at any level. Gifting the same asset during your lifetime does not produce this result: the recipient takes your original cost basis and could face a much larger gain when they eventually sell.
Depreciation Recapture on Rental Property
If you have claimed depreciation deductions on a rental property, the portion of the gain attributable to that depreciation is taxed at a maximum federal rate of 25% when you sell, regardless of your long-term capital gains bracket. This is unrecaptured Section 1250 gain. Profit above the depreciated amount is taxed at the normal long-term rates of 0%, 15%, or 20%.
South Dakota landlords sometimes overlook this because they are used to paying no state tax. A rental held 15 years with $80,000 in accumulated depreciation can trigger up to $20,000 in federal recapture tax on that portion alone, even if the rest of the gain qualifies for the 15% rate. The only way to defer it is through a 1031 exchange.
Deferring the Gain With a 1031 Exchange
A Section 1031 like-kind exchange lets you sell investment or business real estate and reinvest the proceeds in a replacement property without recognizing the gain. The gain is deferred rather than eliminated; it rolls into the basis of the new property. If you keep exchanging through your lifetime, the step-up in basis at death can ultimately erase the deferred gain for your heirs.
The deadlines are strict. You have 45 days from the sale to identify replacement properties in writing and 180 days to close. Both properties must be held for investment or business use; your personal residence does not qualify.9Internal Revenue Service. Like-Kind Exchanges Under IRC Section 1031 Miss either deadline and the full gain becomes taxable in the year of sale. Because South Dakota adds no state tax, the choice to pursue an exchange here comes down entirely to whether the federal deferral is worth the administrative complexity.
Offsetting Gains With Losses
Losses on capital assets offset gains dollar for dollar in the same tax year. If your total losses exceed your gains, you can deduct up to $3,000 of the excess against ordinary income, or $1,500 if married filing separately, and carry the remainder forward indefinitely.10Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses Tax-loss harvesting in South Dakota saves only federal tax, but those savings are real for anyone in the 15% or 20% bracket.
The Real Estate Transfer Fee
South Dakota does not tax capital gains on a real estate sale, but it does charge a small transfer fee when title changes hands. The fee is 50 cents per $500 of value, or roughly $1 per $1,000 of sale price, and the seller pays it.11South Dakota Legislature. South Dakota Code 43-4-21 On a $350,000 home sale, that is $350. Transfers between spouses and transfers under a divorce decree are exempt.
Filing: Federal Only
South Dakota residents do not file a state tax return. There is no state form for capital gains, no state withholding on investment income, and no state estimated payments tied to asset sales.1South Dakota Department of Revenue. Taxes
Everything goes to the IRS. Report capital gains and losses on Schedule D of Form 1040, and use Form 8949 to detail individual transactions before transferring totals to Schedule D.12Internal Revenue Service. About Schedule D (Form 1040), Capital Gains and Losses A rental property sale with depreciation recapture goes on Form 4797. A like-kind exchange requires Form 8824. The net investment income tax is reported on Form 8960. Keep records of your purchase price, improvements, and sale proceeds for every asset; the IRS can challenge a reported basis years after the sale.
