The 2026 picture for New Hampshire residents
New Hampshire has no state income tax, so the 2026 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 New Hampshire throughout the decade.
2026 AMT exemption
The 2026 federal AMT exemption was $88,100 for single filers. The exemption phased out at 25 cents per dollar of AMTI above $626,350, fully eliminating the exemption for higher earners. That is why ISO exercises in New Hampshire during 2026 produced AMT bills that surprised people running first-order mental math.
New Hampshire layer in 2026
New Hampshire did not impose a separate state AMT in 2026, so federal AMT was the only layer. State ordinary tax still applied to any disqualifying disposition income recognized in the same year.
