US Federal Capital Gains Taxation on Equities and Crypto in 2026
In the United States, selling stocks, mutual funds, ETFs, or cryptocurrencies for a profit triggers capital gains taxation under the Internal Revenue Code (IRC). Under IRS Notice 2014-21, virtual currencies and digital assets are legally classified as property, meaning every crypto sale, crypto-to-crypto swap, or spending of crypto on goods constitutes a taxable disposal.
The single most significant determinant of your tax liability is the **holding period**: assets held for one year or less are classified as short-term capital gains and taxed at ordinary income rates up to 37%, while assets held for more than one year qualify for preferential federal long-term capital gains rates of 0%, 15%, or 20%.
IRS Long-Term Capital Gains Tranches for 2026
Net capital gain is calculated as Sale Proceeds minus Adjusted Cost Basis (purchase price plus allowable transaction fees).
For tax year 2026, the statutory federal long-term capital gains brackets under Revenue Procedure 2025-32 are:
**0% Tax Bracket:** Single filers with taxable income up to $49,450 ($98,900 for married filing jointly) pay 0% federal tax on realized long-term capital gains.
**15% Tax Bracket:** Single filers with income between $49,450 and $545,500 ($98,900 to $613,700 joint) pay a 15% statutory rate.
**20% Tax Bracket:** Single filers with taxable income exceeding $545,500 ($613,700 joint) pay the maximum 20% federal capital gains rate.
Net Investment Income Tax (NIIT) and State Taxes
High-income investors with modified adjusted gross income exceeding $200,000 (single) or $250,000 (married filing jointly) face an additional 3.8% Net Investment Income Tax (NIIT) under IRC § 1411, bringing the effective top federal capital gains rate to 23.8%.
Unlike the federal tax code, most US states do not offer preferential rates for long-term capital gains; states such as California, New York, and Massachusetts tax capital gains as ordinary state income, with top marginal rates exceeding 10%.
Taxpayers residing in states with no personal income tax (such as Texas, Florida, Nevada, and Washington for standard equities) pay only federal rates.
Loss Harvesting and the Wash-Sale Rule
Under IRC § 1211, capital losses can offset capital gains dollar-for-dollar. If total losses exceed total gains in a tax year, you can deduct up to $3,000 of excess net capital losses against ordinary wage income ($1,500 if married filing separately), with any remaining loss carried forward indefinitely to future tax years.
For equities and ETFs, the wash-sale rule (IRC § 1091) disallows the tax loss deduction if you purchase a substantially identical security within 30 days before or after the sale date.
Keep meticulous transaction records using cost-basis accounting methods such as Specific Identification (Spec ID) or FIFO to optimize your realized tax liabilities.
Tax Comparison Short-Term vs. Long-Term Capital Gains
Illustrative tax liability on a $25,000 realized gain from an initial $15,000 investment (sale proceeds $40,000) for a standard taxpayer in the 22% ordinary bracket:
| Holding duration | Gross Profit | Tax Classification | Applicable Rate | Federal Tax Owed | Net Profit After Tax |
|---|---|---|---|---|---|
| Under 1 Year (Short-Term) | $25,000 | Ordinary Income | 22.0% | $5,500 | $19,500 |
| Over 1 Year (Long-Term) | $25,000 | Preferential LTCG | 15.0% | $3,750 | $21,250 |
| Held in Roth IRA / 401(k) | $25,000 | Tax-Sheltered | 0.0% | $0 | $25,000 |
Holding an asset for more than 365 days saves $1,750 on a $25,000 profit by transitioning from ordinary income brackets to preferential long-term capital gains rates.
Frequently Asked Questions About US Capital Gains Tax
- Is swapping one cryptocurrency for another a taxable event?
- Yes. Under IRS Notice 2014-21, exchanging Bitcoin for Ethereum is treated as a sale of the first coin at fair market value and immediately triggers capital gains tax on any accrued appreciation.
- What is the difference between short-term and long-term capital gains?
- Assets held for one year or less are short-term gains, taxed at standard ordinary income rates (10% to 37%). Assets held for more than one year receive preferential long-term rates (0%, 15%, or 20%).
- How much capital loss can I deduct against regular W-2 income?
- You can deduct up to $3,000 of net capital losses against ordinary income per year ($1,500 if married filing separately). Remaining unused losses carry forward to future years.
- Do I have to pay tax if I haven't sold my Bitcoin or stocks?
- No. Unrealized paper gains are not subject to tax in the United States until a disposal event (sale, swap, or trade) takes place.
