Capital gains tax is the single biggest tax most investors will pay — and it’s also the most avoidable with the right strategy. New to investing? Start with our How to Start Investing Guide. This guide covers 2026 rates, how gains are calculated, and legal strategies that can save you thousands or even eliminate your capital gains tax entirely.
2026 Long-Term Capital Gains Tax Rates
Long-term capital gains (assets held more than 1 year):
| Tax Rate | Single Filer | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 0% | Up to $48,350 | Up to $96,700 | Up to $64,750 |
| 15% | $48,351-$533,400 | $96,701-$600,050 | $64,751-$566,700 |
| 20% | Over $533,400 | Over $600,050 | Over $566,700 |
Net Investment Income Tax (NIIT): An additional 3.8% surtax applies to investment income if your modified AGI exceeds $200,000 (single) or $250,000 (married). This means the effective top rate is 23.8%.
Short-Term vs. Long-Term: Why It Matters
| Factor | Short-Term (<1 year) | Long-Term (1+ year) |
|---|---|---|
| Tax rate | 10-37% (ordinary income) | 0%, 15%, or 20% |
| Example: $50K gain, $100K salary | ~$11,000 tax | ~$7,500 tax |
| Example: $100K gain, $200K salary | ~$32,000 tax | ~$15,000 tax |
| Planning value | Low | Very high |
The 366-day rule: Selling an investment on day 365 means paying up to 37% tax. Waiting one more day drops the rate to 0-20%. That single day of patience can save thousands.
How to Calculate Your Capital Gains
Formula: Sale Price − Cost Basis = Capital Gain (or Loss)
| Term | What It Means |
|---|---|
| Sale price | What you received for the asset |
| Cost basis | What you paid (purchase price + fees + improvements) |
| Capital gain | Profit — taxed at the rates above |
| Capital loss | Loss — can offset gains + $3,000 of ordinary income |
| Wash sale | Selling at a loss and buying same/similar asset within 30 days — loss is DISALLOWED |
Example Calculation
| Amount | |
|---|---|
| Purchased 500 shares at $40 | $20,000 |
| Plus: trading commission | $0 |
| Cost basis | $20,000 |
| Sold 500 shares at $75 | $37,500 |
| Capital gain | $17,500 |
| Tax (15% long-term rate) | $2,625 |

Real Estate Capital Gains

|---|---|---|
| Single | $250,000 | 2 of last 5 years |
| Married filing jointly | $500,000 | 2 of last 5 years |
Example: Married couple buys home for $400,000, sells for $850,000. Gain = $450,000. Tax owed = $0 (under $500K exclusion).

See Capital Gains Tax on Real Estate.
Cryptocurrency Capital Gains
The IRS treats crypto as property. Every sale, trade, or use triggers a taxable event:

| Buy crypto with USD | No | Not a taxable event |
| Hold crypto | No | Not a taxable event |
| Sell crypto for USD | Yes | Capital gain/loss |
| Trade crypto for crypto | Yes | Capital gain/loss |
| Buy goods with crypto | Yes | Capital gain/loss |
| Receive crypto as payment | Yes | Ordinary income |
| Mining/staking rewards | Yes | Ordinary income |
| Airdrop/fork | Yes | Ordinary income |
See Cryptocurrency Tax Guide and I Forgot to Report Crypto.
Tax-Loss Harvesting
Tax-loss harvesting means selling investments at a loss to offset capital gains:
| Scenario | Without Harvesting | With Harvesting |
|---|---|---|
| Capital gains | $30,000 | $30,000 |
| Capital losses realized | $0 | ($18,000) |
| Net taxable gain | $30,000 | $12,000 |
| Tax (15% rate) | $4,500 | $1,800 |
| Tax savings | $2,700 |
Rules:
- You can offset unlimited gains with losses
- Excess losses offset up to $3,000 of ordinary income per year
- Remaining losses carry forward indefinitely
- Watch the wash sale rule: Can’t buy the same or “substantially identical” security within 30 days before or after the sale

The Bottom Line
The two most important capital gains tax strategies are free: hold investments for more than one year and use tax-advantaged accounts. Beyond that, tax-loss harvesting, strategic timing of sales around income levels, and the $250K/$500K home sale exclusion can eliminate or dramatically reduce your capital gains bill. Don’t let taxes drive your investment decisions entirely — but a 30-second check of your holding period before selling can save you thousands. If your portfolio has grown significantly, consult a CPA once a year to plan your sales strategically.
