Three calculators for the 2026 tax year. Free forever, no account, your numbers never leave your browser.
Crypto Tax Calculator
One buy → one sell: gain or loss, correct holding-period classification, and estimated federal tax using 2026 brackets for your filing status.
Open calculator →Tax-Loss Harvesting Estimator

Open estimator →Staking & Mining Income Tracker
Log every reward at fair market value, get your 2026 ordinary-income total, and export a CSV for your records or preparer.
Open tracker →How the three tools fit together
The three estimators follow the order in which crypto tax questions usually arrive. The Crypto Tax Calculator answers the first one: for a single purchase and a single sale, what is the gain or loss, is it short-term or long-term, and roughly what federal tax does that imply at your filing status. The Tax-Loss Harvesting Estimator answers the planning question that follows in the last quarter of the year: given the gains already realized, how much would selling losing positions before December 31 offset, how much of any excess loss is deductible against ordinary income this year, and how much carries forward. The Staking & Mining Income Tracker handles the income side that trading calculators ignore: rewards are ordinary income at fair market value when you gain control of them, and that value becomes the cost basis of the coins you received, so a running log saves two problems at once.
What they share, and what they leave out
All three run entirely in your browser. Nothing you type is sent to us or stored; close the tab and it is gone, which is why there is no account. Each uses the current federal rates and thresholds published by the IRS, cites the publication it relies on, and shows its assumptions on the page. None of them models state tax, the net investment income tax, the alternative minimum tax, or the interaction between crypto and the rest of your return, and none of them can choose a cost-basis method for you; our cost-basis guide explains why that choice matters and what the broker-reporting rules now require. They are estimators for understanding your position, not a substitute for the software or the professional who prepares the return.
Reading the results
Treat every output as “approximately this, under these assumptions”. If a result surprises you, check the holding period first (a sale one day short of a year is short-term), then the cost basis you entered (fees paid to acquire are part of basis), then the filing status. The common-mistakes guide lists the errors we see most. If you have more than a handful of transactions, the estimators will not scale, and the comparison below is the next step.
