Crypto Tax Calculator
Estimate the tax you owe on cryptocurrency capital gains by entering your gain amount and applicable tax rate. Use it during tax season or before selling to understand your potential tax liability.
About this calculator
Cryptocurrency gains are treated as capital gains in most jurisdictions. This calculator uses the formula: Tax Owed = capitalGains × (taxRate / 100). Capital gains is the profit from selling crypto above your cost basis. The tax rate depends on your holding period and income bracket — short-term gains (held under 1 year) are typically taxed at ordinary income rates, while long-term gains (held over 1 year) qualify for reduced rates in many countries (e.g., 0%, 15%, or 20% in the US). The holdingPeriod field helps you identify which rate category applies to your situation. Note that this calculator estimates federal tax only; state or local taxes may also apply. Always consult a tax professional for advice specific to your situation.
How to use
Suppose you sold Ethereum for a $8,000 capital gain and held it for 8 months, making it a short-term gain. Your marginal income tax rate is 22%. Enter: Capital Gains = $8,000, Tax Rate = 22%. The calculator computes: $8,000 × (22 / 100) = $8,000 × 0.22 = $1,760 in estimated tax owed. If you had held the same ETH for 14 months (long-term), and your long-term rate is 15%, the tax would be $8,000 × 0.15 = $1,200 — saving $560 simply by holding longer.
Frequently asked questions
How is cryptocurrency taxed on capital gains in the United States?
In the US, the IRS treats cryptocurrency as property, so selling it triggers a capital gains tax event. If you held the crypto for one year or less, the gain is short-term and taxed at your ordinary income rate, which can range from 10% to 37%. If held longer than one year, it is taxed at the preferential long-term capital gains rate of 0%, 15%, or 20% depending on your income. Losses can offset gains and potentially reduce your tax bill.
What is the difference between short-term and long-term crypto capital gains tax?
Short-term capital gains apply when you sell crypto held for 12 months or fewer, and these gains are taxed at the same rate as your regular income — potentially as high as 37% in the US. Long-term capital gains apply when you hold for more than 12 months and are taxed at significantly lower rates. Strategically timing your sales to qualify for long-term treatment can result in substantial tax savings, as illustrated by the worked example above.
Do I owe crypto taxes if I trade one cryptocurrency for another?
Yes — in most jurisdictions, including the US, swapping one cryptocurrency for another is a taxable event. When you exchange Bitcoin for Ethereum, for example, the IRS considers this a disposal of Bitcoin at its fair market value at the time of the trade. Any gain above your cost basis is reportable as a capital gain. This catches many investors off guard, so it is important to track the cost basis and value at the time of every trade, not just cash-out events.
