The 0% long-term capital gains rate is one of the most underused breaks in the tax code. It is not a loophole - it is built into the brackets. Here is how it works in 2026.
The 2026 thresholds
Long-term gains are taxed at 0% as long as your total taxable income (ordinary income plus the gain) stays under the 0% ceiling:
| Filing status | 0% applies up to |
|---|---|
| Single | $49,450 |
| Married filing jointly | $98,900 |
| Married filing separately | $49,450 |
| Head of household | $66,200 |
These are taxable income figures - after your standard or itemized deduction. The 2026 standard deduction adds headroom on top.
Who lands in the 0% band
- Early retirees who have stopped working but not yet started Social Security or pensions.
- Students and part-year workers with low wage income.
- Investors in a gap year - a sabbatical, a business loss year, a career break.
In these low-income years you can deliberately sell appreciated assets - “tax-gain harvesting” - and pay nothing federally on gains that fit under the ceiling.
Watch the edge
The gain itself counts toward the income that decides the band. So if you have $40,000 of taxable income (single) and a $30,000 gain, only about $9,450 of the gain fits in the 0% band; the rest is taxed at 15%. Walk through the math on how to figure your bracket, and remember a large gain can also trip the 3.8% NIIT or raise Medicare premiums.
