How We Calculate & Keep This Accurate

Short-term gains are taxed as the top slice of ordinary income: tax(income + gain) − tax(income) at federal ordinary rates. Long-term gains use the 0%/15%/20% preferential brackets stacked on ordinary taxable income, plus 3.8% NIIT when MAGI crosses the threshold. New Hampshire adds nothing — it has no income tax.

No. New Hampshire has no state income tax, so capital gains face only federal tax (0%, 15% or 20% long-term, plus the 3.8% net investment income tax above the MAGI thresholds).

What is the long-term capital gains rate for 2026?

Long-term gains (assets held over a year) are taxed federally at 0%, 15% or 20% depending on taxable income: for a single filer the 0% rate applies up to $49,450 and the 15% rate up to $545,500. A 3.8% net investment income tax can apply above $200,000 MAGI (single).

Is it worth holding an asset longer than a year?

Usually yes. Short-term gains are taxed at your ordinary federal rates (up to 37%), while long-term gains use the lower 0%/15%/20% brackets. On the example above, holding long-term saves $2,100 in federal tax on this gain alone.
