Crypto Short-Term vs Long-Term Capital Gains

When you sell cryptocurrency, the tax bill depends entirely on how long you held it. Crypto short-term vs long-term capital gains are taxed at different federal rates: short-term gains use your ordinary income tax bracket (up to 37%), while long-term gains receive preferential rates (0%, 15%, or 20%). The dividing line is one year of ownership.

Why the One-Year Line Matters

The Internal Revenue Service treats cryptocurrency as property, not currency. When you sell crypto for a gain—whether to fiat, to another cryptocurrency, or to buy a good or service—you trigger a taxable event. The size of your tax bill is not determined by the dollar amount of gain alone; it depends on how long you held the asset before disposal.

Short-term capital gains are taxed as ordinary income. Long-term gains are taxed at preferential federal rates that stop at 20%, regardless of income level. For many taxpayers in higher brackets, this difference is substantial. A $10,000 gain held less than one year might be taxed at 37% federal ($3,700); the same gain held over one year might be taxed at 20% federal ($2,000)—a savings of $1,700 on a single transaction.

Holding Period: How It’s Counted

The clock starts the day after you acquire the cryptocurrency. If you buy Bitcoin on January 15, 2024, your one-year anniversary is January 16, 2025. A sale on January 16, 2025 or later qualifies for long-term treatment.

This rule applies universally: staking rewards, mining proceeds, fork coins, and borrowed crypto all carry acquisition dates. If you receive 1 Bitcoin through mining on March 1, the one-year clock for that Bitcoin starts March 2, independent of any other crypto you own.

Important: the count is based on the acquisition date of the specific asset sold, not a portfolio-wide threshold. You can own Bitcoin and Ethereum simultaneously with different holding periods. When you sell, only the holding period of that particular lot matters.

Tax Rates Across the Brackets

Federal long-term capital gains rates depend on your total taxable income in the year of sale, not the size of the gain itself.

2025 long-term rates (single filers):

• 0% rate: up to $47,025
• 15% rate: $47,026 to $518,900
• 20% rate: $518,901 and above

The same brackets apply to married filing jointly, heads of household, and other statuses (with different income thresholds). Short-term gains are taxed using the ordinary income brackets, which max out at 37%.

Stacking matters. If you have $30,000 in wages and sell crypto for a $40,000 long-term gain, your total taxable income is $70,000. The first $17,025 of the gain sits in the 0% bracket; the remaining $22,975 sits in the 15% bracket. Your effective rate on that $40,000 gain is roughly 9.6%.

When Holding Periods Are Suspended

The holding period is suspended—not reset—when you close a short selling position against cryptocurrency you own, or when you identify a lot using the specific identification basis method and then change identification methods mid-hold. These edge cases are uncommon but can trap unwary traders.

Generally, buying and selling are treated as separate transactions. Taking a loss (a short-term loss against a long-term gain, or vice versa) does not affect the holding period of remaining positions.

Crypto-to-Crypto Swaps and Like-Kind Exchanges

Under current U.S. law, trading one cryptocurrency for another triggers a taxable event immediately—it is not a like-kind exchange. The date of the swap is your disposal date for the original asset, and the acquisition date for the new asset. If you swap Bitcoin for Ethereum on March 1, you trigger tax on any gain in Bitcoin as of March 1; the Ethereum’s holding period starts March 2.

Some traders held older tax positions based on pre-2018 law, when the IRS allowed like-kind treatment for crypto-to-crypto trades. The Tax Cuts and Jobs Act (2017) narrowed like-kind to only real property; crypto swaps now trigger immediate recognition of gains. Any swaps executed after January 1, 2018 should be reported as separate short-term or long-term disposals.

Reporting on Schedule D and Form 8949

The IRS requires you to report capital gains and losses on Schedule D (Capital Gains and Losses) along with Form 8949 (Sales of Capital Assets). Each transaction must be listed with the acquisition date, sale date, basis, proceeds, and resulting gain or loss.

Many exchanges and wallet platforms provide export reports, but you remain responsible for accuracy. If your sale date is December 26, 2024 and acquisition date is December 26, 2023, that is short-term (364 days). The date calculation is automatic for most tax software, but reconciling sales from multiple exchanges and manually moved wallets is where taxpayers often miscount.

State and Local Taxes

Long-term preferential rates apply only to federal tax. Most states tax capital gains at ordinary income rates or flat rates independent of holding period. California, New York, and other high-tax states do not recognize a federal long-term distinction for state purposes. You may pay federal long-term rates (0%–20%) and state rates (5%–13%) on the same gain simultaneously.

A few states—Washington, for example—impose capital gains tax only on long-term gains above a threshold, creating a minor incentive to hold above one year; most ignore the distinction entirely. Confirm your state’s treatment when planning sales.

Tax Planning Around the Threshold

The one-year threshold creates an incentive to hold volatile assets through December 31 of the following calendar year. A $50,000 gain in November triggers short-term tax if sold before the anniversary; waiting two months can cut the federal bill by up to 17 percentage points.

Conversely, realized losses can offset gains without regard to holding period. If you’ve taken short-term losses early in the year, harvesting a short-term gain later may cost you no additional federal tax due to offsetting losses. Holding the asset one more month would not improve your position.

Some traders use tax-loss harvesting to absorb short-term gains at their ordinary rate, then repurchase the same asset later without triggering a wash-sale (because wash rules do not formally apply to crypto). However, the IRS has indicated it may challenge artificial loss transactions, so this strategy remains contested.
