Kansas taxes gains at 5.2% and 5.58%
Kansas uses just two individual rates for 2026. A single filer’s first $23,000 of Kansas taxable income is taxed at 5.2% (the line sits at $46,000 on a joint return) and every dollar past it at 5.58%, so nearly every meaningful gain lands at 5.58%. A single resident going from $60,000 to $110,000 of Kansas taxable income pays $2,790 more, from $3,260.60 to $6,050.60.
Kansas taxes long-term and short-term gains alike, with no holding-period discount, and its two-rate structure means a sale rarely changes which bracket applies to the rest of the year’s income. A future revenue-triggered rate cut is not assumed for 2026.
Kansas approved resident annual comparison
Kansas’s actual 2026 K-40ES schedule publishes 5.2% and 5.58% bands. Married joint returns change bands at $46,000 with a $2,392 upper-band base. The other published status schedule changes at $23,000 with a $1,196 base. Use the current estimate together with the operative statute rather than historical rates or an assumed future revenue-trigger reduction.
State taxable income must already reflect actual Kansas additions, subtractions, deductions and exemptions. A recognized capital gain can affect these annual amounts; the calculator does not infer them from federal proceeds or apply federal preferential bands. State-specific investment exclusions require their own transaction eligibility records. Filing status is independently confirmed for the Kansas calculation, even when the federal selection is already present.
Enter both approved annual taxable balances and complete usable nonrefundable credits in the resident estimate. A $10,000 increase entirely above the applicable upper-band threshold adds $558 before credit changes. Final-liability comparison handles unsupported additional taxes, allocation, refundable credits and prescribed filing-table effects. The published 2026 estimate is not a promise that a future indexed or triggered schedule will be identical.
