Assumptions
- Gain = proceeds − basis, less losses and (for a primary home) the $250,000/$500,000 exclusion.
- Long-term: 0/15/20% bands stacked on other taxable income using the 2026 thresholds; short-term: difference in ordinary tax with and without the gain; collectibles capped at 28%.
- NIIT 3.8% on the lesser of the gain or MAGI above $200,000/$250,000; state = flat %.
Worked example
Gain $25,000, all long-term. Stacked on $70,000 of income it sits entirely in the 15% band → $3,750 federal; no NIIT (income under $200,000); state $1,250 → total $5,000, net proceeds $55,000, 20% effective on the gain. As a short-term gain it would be ordinary income at 22% — $5,500 federal, $1,750 more.

Do I pay capital gains on my home?
Not on the first $250,000 ($500,000 joint) of gain if it was your primary residence for two of the last five years; enter the home option to apply the exclusion.
