This guide explains everything you need to know about calculating your capital gains tax for 2021.
What Are Capital Gains?
Capital gains represent the profit you make when you sell an asset for more than you paid for it. These assets can include:
- Stocks, bonds, and mutual funds
- Real estate (primary residence or investment properties)
- Collectibles like art, antiques, or precious metals
- Cryptocurrency (treated as property by the IRS)
- Business assets or interests
Short-Term vs. Long-Term Capital Gains
The tax treatment of your capital gains depends primarily on how long you held the asset before selling:
| Holding Period | Tax Treatment | 2021 Tax Rates |
|---|---|---|
| Short-term (1 year or less) | Taxed as ordinary income | 10% to 37% (based on tax bracket) |
| Long-term (more than 1 year) | Preferential tax rates | 0%, 15%, or 20% (based on income) |
2021 Long-Term Capital Gains Tax Rates
The long-term capital gains tax rates for 2021 were structured as follows based on filing status and taxable income:
| Filing Status | 0% Rate | 15% Rate | 20% Rate |
|---|---|---|---|
| Single | Up to $40,400 | $40,401 to $445,850 | $445,851+ |

| Head of Household | Up to $54,100 | $54,101 to $473,750 | $473,751+ |
Special Capital Gains Tax Situations
Collectibles Gain Rate (28%)
Gains from the sale of collectibles (art, antiques, coins, precious metals, etc.) are taxed at a maximum rate of 28%, regardless of your income level. This rate applies to the portion of your gain that would otherwise be taxed at 20% if it were a regular capital asset.
Unrecaptured Section 1250 Gain (25%)
When you sell depreciable real estate at a gain, the portion of the gain attributable to depreciation you’ve claimed is taxed at a maximum rate of 25%. This is known as “unrecaptured Section 1250 gain.”
Qualified Small Business Stock (QSBS)
Gains from qualified small business stock may be eligible for a 50%, 75%, or 100% exclusion from taxable income, depending on when the stock was acquired. For stock acquired after September 27, 2010, up to 100% of the gain may be excluded, subject to certain limits.
Net Investment Income Tax (NIIT)
High-income taxpayers may also be subject to the 3.8% Net Investment Income Tax (NIIT) on their capital gains. This tax applies to the lesser of:
- Your net investment income, or
- The amount by which your modified adjusted gross income (MAGI) exceeds:
- $200,000 for single and head of household filers
- $250,000 for married filing jointly
- $125,000 for married filing separately
State Capital Gains Taxes
In addition to federal capital gains tax, most states also tax capital gains as regular income. However, nine states (as of 2021) have no income tax:
- Alaska
- Florida
- Nevada
- New Hampshire
- South Dakota
- Tennessee
- Texas
- Washington
- Wyoming
New Hampshire only taxes interest and dividend income, not capital gains.
States with the highest capital gains tax rates in 2021 included:
- California (13.3%)
- Hawaii (11%)
- New Jersey (10.75%)
- Oregon (9.9%)
- Minnesota (9.85%)
How to Minimize Capital Gains Taxes
There are several legitimate strategies to reduce your capital gains tax liability:
- Hold investments for more than one year to qualify for long-term capital gains rates, which are significantly lower than short-term rates.
- Use tax-loss harvesting by selling losing investments to offset your gains. You can deduct up to $3,000 in net capital losses against ordinary income each year.
- Maximize retirement account contributions since investments in 401(k)s, IRAs, and other retirement accounts grow tax-deferred or tax-free.
- Consider charitable donations of appreciated assets. You can avoid capital gains tax and claim a charitable deduction for the full market value.
- Use the primary residence exclusion which allows you to exclude up to $250,000 ($500,000 for married couples) of gain from the sale of your primary home if you’ve lived there for at least 2 of the past 5 years.
- Invest in Opportunity Zones where you can defer and potentially reduce capital gains taxes by reinvesting gains in designated economically-distressed communities.
- Consider installment sales to spread the recognition of gain over multiple years, potentially keeping you in a lower tax bracket.
Capital Gains Tax on Real Estate
Real estate transactions have special capital gains tax considerations:
- Primary Residence: As mentioned, you can exclude up to $250,000 ($500,000 for married couples) of gain if you’ve lived in the home for at least 2 of the past 5 years.
- Investment Properties: Gains are taxed at capital gains rates, but you may also face depreciation recapture taxed at 25%.
- 1031 Exchanges: You can defer capital gains tax indefinitely by reinvesting proceeds from the sale of investment property into a “like-kind” property through a 1031 exchange.
- Inherited Property: Heirs receive a “step-up in basis” to the property’s fair market value at the time of the original owner’s death, potentially eliminating capital gains tax.
Capital Gains Tax on Cryptocurrency
The IRS treats cryptocurrency as property for tax purposes, meaning:
- Selling crypto for more than you paid is a taxable capital gain
- Using crypto to purchase goods or services is a taxable event
- Exchanging one crypto for another is a taxable event
- Mining crypto creates taxable income
- Receiving crypto as payment is taxable income
Each cryptocurrency transaction must be tracked for cost basis and fair market value at the time of the transaction. Popular accounting methods include:
- FIFO (First-In, First-Out)
- LIFO (Last-In, First-Out)
- Specific Identification
Capital Gains Tax Reporting
Capital gains and losses are reported on IRS Form 8949 and summarized on Schedule D of your Form 1040. You’ll need to provide:
- Description of the property sold
- Date acquired
- Date sold
- Sales price
- Cost basis (original purchase price plus improvements)
- Adjustments to basis
- Gain or loss amount
For complex situations (like inherited property or gift property), you may need to file additional forms or provide additional documentation.
2021 vs. 2022 Capital Gains Tax Changes
While this calculator focuses on 2021 rates, it’s worth noting some key changes that took effect in 2022:
- Income thresholds for capital gains brackets increased slightly for inflation
- No major structural changes to capital gains tax rates
- Proposals to increase long-term capital gains rates for high earners were not implemented
- The wash sale rule (which prevents claiming losses on substantially identical securities bought within 30 days) was proposed to be expanded to include cryptocurrency, but this change hasn’t been finalized
Common Capital Gains Tax Mistakes to Avoid
-
Forgetting to account for all costs when calculating your basis. Remember to include:
- Purchase price
- Commissions and fees
- Improvements (for real estate)
- Other acquisition costs
- Not keeping good records of purchase dates, sale dates, and transaction details. This is especially important for cryptocurrency.
- Assuming all gains are taxed the same without considering special rates for collectibles, real estate, or small business stock.
- Missing deadlines for strategies like 1031 exchanges (45 days to identify replacement property, 180 days to complete the exchange).
- Not considering state taxes which can significantly increase your total tax burden.
- Overlooking tax-loss harvesting opportunities to offset gains with losses.
- Forgetting about the Net Investment Income Tax for high earners.
Frequently Asked Questions About 2021 Capital Gains Tax
What is the capital gains tax rate for 2021?
The 2021 long-term capital gains tax rates are 0%, 15%, or 20% depending on your taxable income and filing status. Short-term capital gains are taxed as ordinary income at rates from 10% to 37%.
How do I calculate my capital gain?
Capital gain is calculated as the selling price minus your adjusted basis in the property. Your adjusted basis is generally your original purchase price plus improvements minus depreciation.
Do I have to pay capital gains tax if I reinvest the proceeds?
Generally yes, unless you use a specific tax-deferral strategy like a 1031 exchange for real estate or reinvest in a qualified Opportunity Zone. Simply reinvesting proceeds doesn’t automatically defer the tax.
How can I avoid capital gains tax on stocks?
You can’t completely avoid capital gains tax on profitable stock sales, but you can:
- Hold investments for more than a year for lower long-term rates
- Use tax-advantaged accounts like IRAs or 401(k)s
- Harvest losses to offset gains
- Donate appreciated stock to charity
- Consider gifting appreciated stock to family members in lower tax brackets
What is the capital gains tax on inherited property?
Inherited property receives a “step-up in basis” to its fair market value at the date of the original owner’s death. This means if you sell the property immediately, you generally won’t owe capital gains tax. If you hold it and it appreciates, you’ll only pay tax on the gain since the date of inheritance.
Do I have to pay capital gains tax if I sell my primary home?
You may qualify to exclude up to $250,000 ($500,000 for married couples) of gain from the sale of your primary home if you’ve lived there for at least 2 of the past 5 years. Any gain above these amounts is taxable.
How are capital losses treated?
Capital losses can be used to offset capital gains. If your losses exceed your gains, you can deduct up to $3,000 against ordinary income. Any remaining losses can be carried forward to future years.
Are capital gains included in adjusted gross income?
Capital gains are included in your taxable income, which is used to calculate your adjusted gross income (AGI). However, they’re reported separately on Schedule D and may be taxed at different rates than ordinary income.
