Kansas taxes the gain at nearly 6%, on top of what the IRS already takes.
Kansas capital gains are taxed as ordinary income, up to 5.7% at the state level. Add the federal 20% and the 3.8% NIIT and an investment property seller can face up to 29.5% of the gain.
Kansas doesn't treat capital gains any differently than a paycheck; the same bracket structure applies, topping out at 5.7%. Combined with the federal side, the ceiling lands at 29.5%. See your own figure, with recapture included, in the capital gains tax calculator.
Send the proceeds into a like-kind property instead of your bank account and the 29.5% bill waits. The 1031 exchange calculator handles your specific basis and reinvestment amount, and the timeline calculator tracks the 45- and 180-day deadlines.
