Federal long-term capital gains rates (2026)
Federal long-term capital gains (assets held more than one year) are taxed at 0%, 15%, or 20% depending on taxable income, plus a 3.8% Net Investment Income Tax (NIIT) on investment income above $200k single / $250k MFJ. Short-term gains (held one year or less) are taxed at ordinary federal rates of 10% to 37%.
For 2026, the 0% bracket applies up to approximately $48,350 single / $96,700 MFJ of total taxable income, the 15% bracket runs to roughly $533,400 single / $600,050 MFJ, and the 20% rate applies above those thresholds.
California treatment of capital gains
California does not provide a preferential rate for long-term capital gains. Both short-term and long-term gains are generally taxed as ordinary income at the state's marginal rate of approximately 9.30% for high earners. The combined federal + California rate on long-term gains for top earners is approximately 33.10% (20% federal + 3.8% NIIT + 9.30% state).
Capital losses can offset capital gains plus up to $3,000 of ordinary income per year on the federal return, with unused losses carried forward indefinitely. Most states conform to federal rules for loss treatment, though some have their own carryforward limits.
Home sale exclusion (Section 121)
The Section 121 exclusion lets you exclude up to $250,000 (single) or $500,000 (MFJ) of gain on the sale of a primary residence, provided you owned and used the home as your main home for at least 2 of the last 5 years. California generally conforms to the federal exclusion, meaning excluded gain is not taxed at the state level either.
Any gain above the exclusion amount is taxed at federal LTCG rates and California's 9.30% state rate. Track basis carefully — capital improvements (kitchen remodels, additions, new roofs) raise basis and reduce taxable gain.
Capital gains planning for California residents
Common strategies that work well for California households:
- Hold appreciated assets at least 12 months and one day to qualify for long-term rates.
- Harvest losses in down years to offset realized gains.
- Time large gain realizations for years of lower other income (sabbatical, retirement gap year).
- Use Qualified Opportunity Zone funds to defer and reduce federal gain.
- Donate appreciated stock to a Donor-Advised Fund instead of cash — avoids the gain entirely.
- For very large gains, run a residency-change analysis — moving to a no-tax state before realization can save 9.30% of the gain.
Worked example · California, 2026
Consider a California investor with a $100,000 long-term capital gain in 2026 and taxable income in the 15% federal bracket. Federal LTCG tax: $15,000. NIIT (if MAGI above threshold): $3,800. California state tax: $9,300.
Total tax on the $100,000 gain: approximately $28,100, leaving roughly $71,900 after tax.
