Capital gains tax in Kansas (2026): selling a business, real estate or farm
Two brackets, and the top one starts early
Since tax year 2024 Kansas has had just two individual brackets: 5.2% and 5.58% (K.S.A. 79-32,110, as amended by 2024 SB 1). The 5.58% rate begins at $46,000 of Kansas taxable income on a joint return and $23,000 for everyone else. For anyone selling a business, a farm or a building, that means effectively every dollar of gain is taxed at 5.58% in 2026, the same rate that applies to wages, interest and recapture.
There is no Kansas holding-period discount, no percentage exclusion and no deduction for selling a Kansas business. Federal rates are a separate layer: 0%, 15% or 20% on long-term gain, the 20% rate starting above $613,700 of joint taxable income for 2026 (Rev. Proc. 2025-32). The long-term capital gains guide covers that side.
What a $2.4 million building sale costs in Kansas
In the first example a Kansas couple sells a commercial building held for years. Of the $2.4 million gain, $400,000 is unrecaptured Section 1250 gain, which the IRS taxes at up to 25% (IRC 1(h), 2026) while Kansas taxes all of it at 5.58%. The sale causes $510,653 of federal income tax, $86,260 of net investment income tax and $133,920 of Kansas tax, an effective rate of 30.5% on the gain.
Spreading the same gain over five years (second example) brings the total to $586,831, a $144,002 reduction. Look at where it comes from: the Kansas line is $133,920, the same as the cash sale, because 5.58% already applies above $46,000. In Kansas the payoff from an installment sale is federal: more gain taxed at 15% instead of 20%, and less net investment income tax. More on rentals: capital gains tax on commercial property.
The exclusions Kansas used to have
Searchers often find old references to a Kansas capital gains break. Those subtractions were temporary. K.S.A. 79-32,117(c)(xxii) let farmers subtract net gain on breeding, dairy and draft cattle, horses and other livestock, and (c)(xxiv) covered Kansas-grown Christmas trees held six years, but both applied only to tax years beginning after 2012 and ending before Jan. 1, 2017. A 2026 sale of cattle, land or a business gets no Kansas subtraction.
That makes the federal rules the main lever for Kansas farmers. Land and raised breeding stock are usually Section 1231 gain, machinery triggers Section 1245 recapture at ordinary rates, and farm property is exempt from the Section 453A interest charge on large notes (IRC 453A(b)(3)). See capital gains tax on farmland and farm installment sales.
Moving away does not take Kansas land with you
Kansas taxes a nonresident with a ratio formula: compute the tax as if the person were a Kansas resident on all income, then multiply by the share of income that is Kansas-source (K.S.A. 79-32,110(b), 2026). Gain on Kansas real estate and tangible business property is Kansas-source, so a seller who moves to Texas and then sells a Kansas building or farm still files a Kansas return, and a big gain pushes the ratio toward 100%.
Moving does help with gain on stock or other intangibles, which generally follows the owner's residence on the date of sale. If you are weighing it, read moving states before a sale and compare Missouri, Oklahoma, Nebraska and Colorado. Installment payments on Kansas property received after a move are still Kansas-source.
Rate cuts depend on a revenue trigger
2025 SB 269 set up automatic cuts: each August 15 the budget director tests whether prior-year revenue beat an inflation-adjusted base and whether the rainy day fund holds at least 15% of receipts (KDOR Notice 25-06, Oct. 2, 2025). If both pass, rates fall proportionally until the lowest reaches 4%. The first test failed by about $88 million, so there is no reduction for tax year 2026. Timing a sale around a possible cut is a bet on revenue reports, not a scheduled rate.
Retirees, heirs and the rest of the Kansas picture
A large gain can make up to 85% of Social Security taxable federally, but Kansas subtracts all Social Security benefits included in federal income for tax years after 2023 (KDOR Notice 24-08, 2024). The federal Medicare premium surcharge and net investment income tax still respond to the gain, which big sale year phase-outs walks through.
Kansas has no estate tax for deaths after Dec. 31, 2009 (KDOR Notice 10-07), and heirs receive a federal stepped-up basis, so holding until death can remove built-in gain entirely. Business owners should also read capital gains tax on the sale of a business.

What to know
The engine applies 5.58% to the full Kansas gain, which matches the statute for any seller well above the $46,000 joint bracket line. Spreading payments helps federally but leaves the Kansas bill nearly unchanged, and the buyer's credit becomes your risk until the note is paid, so secure it with a first-position mortgage, a meaningful down payment and personal guarantees where the buyer is an entity. Kansas rate cuts are conditional and should not drive the closing date on their own.
Worked example
Married couple in Kansas, $120,000 of other income, sells a commercial building in 2026: $2,000,000 long-term gain plus $400,000 of unrecaptured Section 1250 gain from depreciation. Same couple and gain, paid in five equal annual installments from 2026; under the installment rules the $400,000 of Section 1250 gain is reported first, in year one. Later years use projected federal tables.

| Unrecaptured Section 1250 gain (25% max) | $400,000 | $400,000 |
| Federal income tax on the sale | $510,653 | $386,411 |
| Net investment income tax (3.8%) | $86,260 | $66,500 |
| State income tax on the sale | $133,920 | $133,920 |
| Total tax caused by the sale | $730,833 | $586,831 |
| Effective rate on the gain | 30.5% | 24.5% |
| Gain kept after these taxes | $1,669,168 | $1,813,170 |
