The 2024 picture for Washington residents
Washington has no state income tax, so the 2024 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 Washington throughout the decade.
2024 AMT exemption
The 2024 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 Washington during 2024 produced AMT bills that surprised people running first-order mental math.
Washington layer in 2024
Washington did not impose a separate state AMT in 2024, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
