How accurate is a crypto tax calculator?

It gets you to the right order of magnitude for planning and estimated payments. A filed return still requires per-lot cost basis, per-wallet tracking, and reconciliation against every 1099 the exchanges issued.

Are short-term and long-term crypto gains taxed differently?

Yes. Crypto held one year or less is taxed at ordinary income rates up to 37%. Crypto held more than a year is taxed at 0%, 15%, or 20% depending on your total taxable income.

Does the calculator store my numbers?

No. Everything runs in your browser and nothing is transmitted or saved on our servers.

How much should I set aside for crypto taxes?

Use the estimate here as a floor, add your state rate if you did not include it, and set the cash aside in the same quarter you realize the gain so underpayment penalties never start.

Planning estimate only, using current federal brackets, the standard deduction, and a flat state rate. It ignores credits, AMT, NIIT, the Social Security wage cap, phase-outs, and state-specific capital gain rules. It is not tax advice or a filed return.
