Calculation detail
Tax Breakdown
The breakdown shows how the calculator separates ordinary crypto income, short-term gains, long-term gains, losses, NIIT, and state estimates.
What This Crypto Tax Calculator Is Designed to Answer
This page is built around one search intent: estimating how much U.S. tax may apply to realized crypto gains after separating short-term gains, long-term gains, crypto ordinary income, and losses. It does not try to predict crypto prices, project future portfolio value, or replace tax software.
For many taxpayers, the important planning question is not simply whether crypto was profitable. It is whether the taxable activity is short term or long term, whether rewards were ordinary income, whether losses can offset gains, and whether income is high enough for the Net Investment Income Tax to matter.
Methodology
- Short-term gains: estimated by adding net short-term gains on top of ordinary taxable income and applying progressive ordinary income tax brackets.
- Long-term gains: estimated with the 0%, 15%, and 20% long-term capital gains brackets after accounting for taxable ordinary income and short-term gains.
- Crypto ordinary income: staking, mining, airdrop, and reward income are added to ordinary income when the option is turned on.
- Losses: capital losses offset short-term gains first, then long-term gains. Remaining losses offset ordinary income up to the annual capital loss limit used in the calculator.
- NIIT: when enabled, the calculator estimates the 3.8% Net Investment Income Tax based on filing status and the lower of net investment income or income above the threshold.

Crypto Tax Calculator FAQ
How do I estimate tax on crypto gains?
Start by separating short-term gains, long-term gains, crypto ordinary income, and losses. Short-term gains are generally taxed with ordinary income rates, while long-term gains use long-term capital gains rates after considering your taxable income and filing status.
Are short-term crypto gains taxed differently from long-term crypto gains?
Yes. For U.S. federal tax purposes, crypto held for one year or less is generally short term. Crypto held for more than one year is generally long term. The holding period can materially change the estimated tax rate.
Does staking, mining, or airdrop income use capital gains tax rates?
Not usually. Staking rewards, mining income, and airdrops are commonly treated as ordinary income when received. A later sale may also create a separate capital gain or loss based on cost basis and sale price.
Can crypto losses reduce my tax estimate?
Capital losses can offset capital gains. If losses exceed gains, a limited amount may offset ordinary income for the year, with unused losses generally carried forward. This calculator uses the common annual loss-limit framework for a simplified estimate.
Does this calculator include the Net Investment Income Tax?
Yes, if you turn on the NIIT option. The calculator estimates the 3.8% Net Investment Income Tax using the filing-status threshold and the lower of net investment income or the amount over the threshold.
Does this calculator include state crypto taxes?
Only as an optional flat-rate estimate. State tax rules vary widely, so the state field is a rough planning input rather than a state-specific tax calculation.
Does the calculator choose a cost basis method?
No. It does not choose FIFO, specific identification, average cost, or any other lot method. Enter gains and losses after applying the cost basis method you use in your records.
Can I use this calculator for Form 8949 or Schedule D?
Use this calculator as a planning estimate only. It does not create Form 8949, Schedule D, or tax software files. Compare any estimate with your exchange history, wallet records, and tax forms.
Is this crypto tax calculator tax advice?
No. This calculator is for general informational estimates and simple arithmetic checks. It is not tax, legal, accounting, or financial advice.
