Combined rate and how to defer it in Alaska.
Alaska has no state income tax, so investment property sellers owe only the federal rate: up to 23.8% (20% federal + 3.8% NIIT, 0% state). That is the lowest combined rate in the country, shared with a handful of other no-tax states.
Alaska imposes no state income tax, so your capital gains exposure is entirely federal. Use the capital gains tax calculator to estimate federal-only capital gains and depreciation recapture.
Even at 23.8%, a 1031 like-kind exchange defers the entire federal bill by reinvesting into a replacement property. Model it in the 1031 exchange calculator and check your deadlines in the timeline calculator.
