Crypto Tax Calculator (US)

This crypto tax calculator helps estimate US crypto gains, losses, and potential capital gains tax using simplified assumptions. It is designed for planning, not for preparing a complete tax return.

Crypto tax can be complicated because taxable events may include selling crypto, swapping one token for another, spending crypto, receiving rewards, or disposing of assets after fees. Cost basis and holding period are especially important.

If you bought crypto for $5,000 and later sold it for $8,000, the gain before fees is $3,000. If it was held for more than one year, it may be treated as a long-term capital gain; if held for one year or less, it may be short-term.

Fees, multiple purchases, partial sales, and token swaps can change the cost basis. That is why clean transaction records matter.

Crypto activity can span wallets, exchanges, staking platforms, and DeFi protocols. If records are incomplete, it becomes much harder to calculate cost basis, holding period, gains, and losses accurately.

Use the calculator to estimate the scale of a tax liability, then reconcile the result against detailed transaction history before filing.

Track buys, sells, swaps, transfers, fees, rewards, and dates. Set aside cash for estimated tax when realizing gains, especially after a large sale.

Tax rules and reporting requirements can change, so confirm current rules with IRS guidance or a qualified crypto tax professional.

Use this calculator for one simplified US crypto disposal where you know cost basis, sale amount, transaction fees, holding period, and the tax rate you want to test.

The component subtracts fees from sale proceeds, compares net sale proceeds with cost basis, and applies the entered tax rate only to positive gain.

It does not handle multiple lots, FIFO, specific identification, staking, mining, airdrops, swaps across many tokens, wash-sale uncertainty, or full IRS reporting.

Use capital gains tax us for non-crypto investment sales, and use estimated tax when a gain creates a payment-planning question.

Label saved scenarios with token, dates, cost basis source, and rate assumption because crypto records can fragment across wallets and exchanges.

Treating cash withdrawal as the only taxable event. Swaps, sales, rewards, and other transactions can have different treatment.

Using zero basis because records are missing instead of reconstructing exchange and wallet history.

Entering total portfolio value when the calculator is built for one disposal scenario.

Assuming the holding-period selector chooses the correct tax rate automatically. The rate is still the manual rate entered.

Forgetting state tax, losses, fees, token-specific records, and income treatment for rewards or mining.

Example: enter a $5,000 cost basis, $8,500 sale amount, $0 fees, short-term holding period, and a 15% estimated tax rate.

The calculator estimates gain, tax on the positive gain, net sale proceeds, and profit after tax.

Add transaction fees when they should reduce net proceeds in the scenario.

Change the tax rate only after deciding whether you are modelling short-term, long-term, state, or combined tax assumptions.

Use capital gains tax us for stocks, funds, property, or other non-crypto sale scenarios.

Use net investment income tax if crypto gains may be part of a NIIT calculation.

Use estimated tax if active trading creates quarterly payment planning after you estimate annual tax.

Use tax software or a crypto tax export when many lots, wallets, or exchanges are involved.

Check exchange CSVs, wallet transfers, acquisition dates, disposal dates, fees, and cost-basis method.

Check whether the transaction is a sale, swap, reward, mining income, airdrop, gift, or transfer between your own wallets.

Check whether losses, state tax, NIIT, or missing basis records require a more detailed filing workflow.

Rerun this crypto tax calculator when sale amount, cost basis, fees, holding period, or estimated tax rate changes.

Recheck after importing final exchange data because cost basis and fees may differ from rough notes.

If this estimate differs from crypto tax software, trace the lot selection, proceeds, fees, holding period, and tax-rate assumption separately.
