United States Crypto Tax Calculator

In the United States, the Internal Revenue Service (IRS) treats cryptocurrency as property, not currency. This means every disposal — selling for USD, swapping for another coin, or spending on goods — triggers a capital gains event. The US system is unique because it applies completely different tax rates depending on how long you held the asset. Short-term gains (held one year or less) are taxed as ordinary income using the same progressive brackets that apply to your salary. Long-term gains (held more than one year) receive preferential rates of 0%, 15%, or 20% based on your total taxable income. Understanding this bifurcation is essential because the tax difference between a short-term and long-term sale can be dramatic, sometimes exceeding 15-20 percentage points.

To estimate your US crypto tax, first determine whether your gain is short-term or long-term by checking if you held the asset for more than 12 months. For short-term gains, add the full gain to your other taxable income and apply the ordinary income tax brackets (10%, 12%, 22%, 24%, 32%, 35%, or 37%). For long-term gains, use the separate preferential brackets: 0% if your total taxable income is below roughly $48,350 (single filer), 15% if it falls between that threshold and $533,400, and 20% if it exceeds the upper limit. The calculator below models both scenarios automatically. You can also reduce your gain by adding purchase fees to your cost basis and subtracting sale fees from proceeds. Losses can offset gains of the same type first, then up to $3,000 of excess losses can offset ordinary income annually, with any remainder carried forward indefinitely.

Track your gains throughout the year using the PnL calculator so you are prepared for end-of-year tax filing. To work out your cost basis across multiple buys, use the DCA calculator.

US taxpayers report every crypto disposal on Form 8949 and summarize on Schedule D of Form 1040. Each sale requires the date acquired, date sold, proceeds, cost basis, and gain or loss. If you have many trades, use crypto tax software to generate Form 8949 automatically. The filing deadline is 15 April, with an automatic extension to 15 October available via Form 4868. Remember that estimated quarterly taxes may be required if you have significant crypto gains without withholding.

A common US crypto tax mistake is failing to report crypto-to-crypto swaps, which the IRS treats as taxable barter transactions. Another error is ignoring the wash-sale rule, which disallows loss deductions if you repurchase the same asset within 30 days before or after the sale. Many taxpayers also miscalculate cost basis by not including trading fees or by using incorrect accounting methods. Always use FIFO unless you have specifically elected a different method with the IRS.
