Long-Term Capital Gains Tax: Rates, Brackets & Planning
⚡ Key Takeaways
- Long-term capital gains apply to assets held for more than one year
- Preferential tax rates of 0%, 15%, or 20% apply depending on taxable income
- The 3.8% Net Investment Income Tax (NIIT) adds a surcharge for high earners
- Strategic use of long-term holding periods is one of the most effective tax optimization tools
What Are Long-Term Capital Gains?
A long-term capital gain is the profit from selling an asset you have held for more than one year. The IRS rewards patient investors with significantly lower tax rates compared to short-term capital gains, which are taxed as ordinary income.
The holding period starts the day after you purchase a security. To qualify for long-term treatment, you must sell the asset after at least one year and one day from the purchase date. This single-day distinction can mean the difference between a 37% tax rate and a 15% rate.
Long-term capital gains treatment applies to stocks, bonds, ETFs, mutual funds, real estate, and most other investment assets. The preferential rates exist as a policy incentive to encourage long-term investment over short-term speculation.
Long-Term Capital Gains Tax Rates
The federal government taxes long-term capital gains at three rates: 0%, 15%, and 20%. Your rate depends on your taxable income and filing status.
| Tax Rate | Single Filer | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 0% | Up to $47,025 | Up to $94,050 | Up to $63,000 |
| 15% | $47,026 – $518,900 | $94,051 – $583,750 | $63,001 – $551,350 |
| 20% | Over $518,900 | Over $583,750 | Over $551,350 |
These thresholds are separate from ordinary income tax brackets. A married couple with $90,000 in taxable income would pay 0% on their long-term capital gains — effectively tax-free profits.
Pro Tip
The Net Investment Income Tax (NIIT)
High earners face an additional 3.8% surtax on net investment income, including long-term capital gains. The NIIT applies when your modified adjusted gross income (MAGI) exceeds:
- $200,000 for single filers
- $250,000 for married filing jointly
- $125,000 for married filing separately
This means the true maximum federal rate on long-term gains is 23.8% (20% + 3.8%). While higher than the base 20% rate, it remains far below the top short-term rate of 40.8%.
NIIT = 3.8% × lesser of (Net Investment Income, MAGI − Threshold)
Example: Single filer, MAGI $300,000, Net Investment Income $80,000
NIIT = 3.8% × min($80,000, $100,000) = 3.8% × $80,000 = $3,040
How Much You Save With Long-Term Rates
The tax savings from qualifying for long-term treatment are substantial. Consider a trader in the 32% marginal bracket who realizes a $50,000 gain:
| Scenario | Tax Rate | Tax Owed | Net Gain |
|---|---|---|---|
| Short-term gain | 32% | $16,000 | $34,000 |
| Long-term gain | 15% | $7,500 | $42,500 |
| Savings | — | $8,500 | — |
Over a career of investing, these savings compound dramatically. An investor who converts $50,000 per year from short-term to long-term treatment saves roughly $8,500 annually — over $170,000 across 20 years, before considering the time value of that money.
Calculating Your Long-Term Capital Gain
Your capital gain equals the sale price minus your cost basis minus any selling expenses.
Long-Term Capital Gain = Sale Price − Cost Basis − Selling Expenses
Example: Buy 100 shares at $50 ($5,000) + $10 commission = $5,010 basis
Sell 100 shares at $80 ($8,000) − $10 commission = $7,990 proceeds
Capital Gain = $7,990 − $5,010 = $2,980
Your cost basis includes the purchase price plus any commissions, fees, or reinvested distributions. For inherited assets, the cost basis is typically the fair market value on the date of the decedent's death (stepped-up basis). For gifted assets, the cost basis generally carries over from the donor.
Cost basis methods matter when you have purchased the same stock at different prices:
- FIFO: First shares purchased are first sold
- Specific identification: Choose which tax lots to sell
- Average cost: Available for mutual funds and some ETFs
Qualified Dividends and Long-Term Rates
Qualified dividends also receive the same preferential long-term capital gains rates. To qualify, dividends must meet specific holding period requirements and be paid by a U.S. corporation or qualifying foreign entity.
You must hold the stock for at least 61 days during the 121-day period beginning 60 days before the ex-dividend date. This prevents investors from buying stocks solely to capture a dividend at reduced rates.
For more details on how dividends are taxed, see our dividend tax rate guide.
Strategies to Maximize Long-Term Treatment
Hold for at least one year and one day. This is the most straightforward strategy. Before selling a profitable position, check whether waiting a few more days or weeks would qualify the gain for long-term treatment.
Use tax-lot selection. When selling partial positions, use specific identification to sell shares with the longest holding period first. This maximizes the portion of your gain that qualifies for long-term rates.
Pair with tax-loss harvesting. Use tax-loss harvesting to offset any remaining short-term gains. Short-term losses are most valuable when they offset short-term gains taxed at higher rates.
Invest in tax-advantaged accounts for active trading. Reserve taxable accounts for long-term holdings and use IRAs or 401(k)s for shorter-term trading strategies where gains would otherwise be taxed at ordinary income rates.
Consider tax-managed funds. Index funds and tax-managed mutual funds minimize capital gains distributions, helping investors maintain long-term holding periods.
Pro Tip
State Tax Treatment of Long-Term Gains
Unlike the federal government, most states do not offer preferential rates for long-term capital gains. In most states, capital gains — both short-term and long-term — are taxed as ordinary income.
Notable exceptions include:
| State | Long-Term Capital Gains Treatment |
|---|---|
| No income tax states (FL, TX, NV, WY, etc.) | No state capital gains tax |
| New Hampshire | Taxes interest and dividends only (no capital gains tax) |
| Wisconsin | 60% exclusion on certain long-term gains |
| Montana | Capital gains credit available |
For most investors, state taxes add 3% to 13% on top of federal long-term capital gains rates. This makes the total effective rate range roughly 15% to 37% depending on your state.
Reporting Long-Term Capital Gains
Long-term capital gains are reported on Form 8949 (Part II for long-term transactions) and summarized on Schedule D of Form 1040. Your broker provides a 1099-B with transaction details.
Key reporting considerations:
- Verify your broker's cost basis reporting matches your records
- Report any adjustments for wash sales, gifted stock basis, or inherited stock basis
- Ensure the correct holding period is listed for each transaction
- Carry forward any unused capital losses from prior years on Schedule D
Long-Term Capital Gains on Special Assets
Certain assets have unique long-term capital gains rules:
Collectibles (art, coins, antiques) are taxed at a maximum rate of 28%, higher than the standard 20% maximum.
Section 1202 stock (Qualified Small Business Stock) may qualify for a 100% exclusion on gains up to $10 million or 10 times the adjusted basis, if held for at least five years.
Real estate gains may be subject to depreciation recapture at 25% before the standard long-term rates apply.
Section 1256 contracts (futures, index options) receive automatic 60/40 treatment — 60% of gains are taxed as long-term regardless of how long you held the contract. See our options taxes guide for more.
FAQ
What is the holding period for long-term capital gains?
You must hold an asset for more than one year (at least one year and one day) to qualify for long-term capital gains treatment. The holding period starts the day after purchase and includes the day of sale.
Can I pay 0% on long-term capital gains?
Yes. Single filers with taxable income up to $47,025 and married couples filing jointly with taxable income up to $94,050 pay 0% on long-term capital gains. This is particularly beneficial for retirees or those in lower income years.
Do long-term capital losses offset short-term gains?
Yes. After long-term losses offset long-term gains, any excess long-term losses can offset short-term gains. However, using short-term losses against short-term gains first provides a greater tax benefit due to the rate differential. See long-term vs. short-term for strategy details.
How do long-term capital gains affect my tax bracket?
Long-term capital gains are taxed at their own separate rates and do not push your ordinary income into a higher bracket. However, they can increase your MAGI, potentially triggering the NIIT or affecting other income-based thresholds.
Are ETF gains taxed as long-term capital gains?
If you hold an ETF for more than one year, your gains from selling are taxed at long-term capital gains rates. ETFs are also generally more tax-efficient than mutual funds because of the in-kind creation/redemption process, which minimizes capital gains distributions.
