The 2023 picture for Alaska residents
Alaska has no state income tax, so the 2023 tax picture for its residents was entirely federal: ordinary rates up to 37%, capital gains up to 23.8%, and federal Medicare taxes. That was the structural advantage that drove tech-employee relocations into Alaska throughout the decade.
2023 AMT exemption
The 2023 federal AMT exemption was $85,700 for single filers. The exemption phased out at 25 cents per dollar of AMTI above $609,350, fully eliminating the exemption for higher earners. That is why ISO exercises in Alaska during 2023 produced AMT bills that surprised people running first-order mental math.
Alaska layer in 2023
Alaska did not impose a separate state AMT in 2023, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
