Calculate short-term capital gains tax on cryptocurrency held less than one year. Estimate federal tax owed based on your income tax bracket.
Short-term capital gains on cryptocurrency are profits from selling digital assets held for one year or less. Unlike long-term gains, which receive preferential tax rates, short-term gains are taxed at your ordinary income tax rate — the same rate applied to wages and salaries. Depending on your income bracket, this rate can range from 10% to 37% at the federal level.
This calculator helps you estimate the federal tax owed on short-term crypto gains by applying the appropriate marginal tax bracket to your net gain. Simply enter the proceeds from your sale, your cost basis, and your taxable income to see your estimated tax liability. The tool accounts for the 2025/2026 federal income tax brackets.
Understanding your short-term tax exposure is critical for active traders who frequently buy and sell crypto within the same year. Day traders, swing traders, and anyone who sold crypto within 365 days of purchase should use this calculator to estimate their quarterly or annual tax obligation and avoid surprises at filing time.
Many crypto traders underestimate how much they owe on short-term gains because they assume crypto gets a flat tax rate. In reality, short-term crypto gains stack on top of your regular income and are taxed at marginal rates. A trader in the 32% bracket who realizes $20,000 in short-term gains could owe $6,400 in federal taxes alone. This calculator reveals the true after-tax profit so you can plan cash reserves for tax payments and decide whether holding longer might save you money.
Short-Term Gain = Proceeds − Cost Basis Tax Owed = Short-Term Gain × Marginal Income Tax Rate After-Tax Profit = Short-Term Gain − Tax Owed
Result: $1,100 estimated tax
You sold crypto for $15,000 that cost $10,000, yielding a $5,000 short-term gain. With $60,000 taxable income (single filer), the gain falls in the 22% bracket. Tax owed = $5,000 × 22% = $1,100. Your after-tax profit is $3,900.
The IRS treats cryptocurrency as property. When you sell or trade crypto held for one year or less at a profit, that profit is taxed at your ordinary income tax rate. This rate depends on your total taxable income and filing status. For 2025, federal brackets range from 10% to 37%.
The simplest strategy is to hold assets for longer than one year to qualify for long-term rates. If you must sell short-term, consider harvesting losses on other positions to offset gains. Timing sales across tax years can also help manage bracket exposure.
The IRS requires you to track the date acquired, date sold, cost basis, and proceeds for every crypto transaction. Crypto tax software can automate this by importing exchange data. Maintaining accurate records is essential to correctly classify gains as short-term or long-term and to defend your return in an audit.
Any profit from selling, trading, or spending cryptocurrency that you held for one year or less is a short-term capital gain. The holding period starts the day after you acquire the asset and ends on the day you dispose of it. If you held the crypto for exactly 365 days or fewer, it is short-term.
Short-term gains are taxed at your ordinary income tax rate (10-37%), while long-term gains receive preferential rates of 0%, 15%, or 20%. For high-income taxpayers, the difference can be significant — 37% vs 20% on the same gain amount.
Yes. Trading one cryptocurrency for another is a taxable event. If you bought ETH with BTC, you must calculate the gain or loss on the BTC you disposed of based on its fair market value at the time of the trade minus your cost basis.
Yes, short-term losses first offset short-term gains. If your net short-term result is still a loss, it can then offset long-term gains. Any remaining net capital loss (up to $3,000 per year) can offset ordinary income.
In most states, yes. States that impose income tax typically tax capital gains as ordinary income. A few states like California tax gains at the same rate as wages, adding up to 13.3% on top of federal taxes. States without income tax (TX, FL, WA, etc.) do not impose additional tax.
You must reconstruct your cost basis from exchange records, wallet transactions, and blockchain data. The IRS expects you to report accurate cost basis. If records are unavailable, some taxpayers use a zero cost basis (worst case) or work with a crypto tax professional to reconstruct records.
