The 2025 picture for New Hampshire residents
New Hampshire has no state income tax, so the 2025 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.
2025 federal capital gains brackets
In $2025, federal long-term capital gains rates were 0% up to approximately $48,350, 15% up to approximately $533,400, and 20% above. The 3.8% NIIT added for MAGI above $200,000 single, producing a 23.8% top federal rate on long-term equity sales.
New Hampshire treatment in 2025
New Hampshire imposed no state income tax on capital gains in 2025, so federal 23.8% was the ceiling. This was a meaningful structural advantage for equity sellers compared to California and New York peers.
