Head of household capital gains brackets

Head of household (HoH) filing status provides more favourable ordinary and long-term capital gains thresholds than single status, but you must qualify under IRS rules — generally unmarried (or considered unmarried) and paying more than half the cost of keeping up a home for a qualifying person.

HoH long-term capital gains 0% and 15% thresholds sit between single and joint amounts. NIIT generally uses the same $200,000 MAGI threshold as single filers. Misclaiming HoH is a common audit flag, so confirm eligibility before selecting it in the calculator.

State filing status may differ from federal status in some situations. Use this page for federal planning estimates, then open your state calculator for the state layer.

See methodology for bracket sources (including Rev. Proc. 2025-32) and IRS Topic 409 for capital gains basics.
