US Federal Crypto Tax Calculator — 2025 Tax Year
Computes federal capital gains tax on a single crypto sale using 2025 IRS brackets (returns filed April 2026). State tax not included — add separately.
Long-term (held > 1 year): 0% / 15% / 20% brackets based on total taxable income.
This calculator handles one trade. Real portfolios have hundreds or thousands of transactions across exchanges, wallets, DeFi protocols and NFTs. Tax software handles lot-matching (FIFO/LIFO/HIFO), wash-sale checks, missing cost basis from transfers, and generates IRS-ready Form 8949 in minutes.

Methodology & sources
Short-term gains (held ≤ 365 days) are taxed as ordinary income using the 2025 IRS brackets (Rev. Proc. 2024-40).
Long-term gains (held > 365 days) use the preferential 0 / 15 / 20% brackets. 2025 thresholds: single $48,350 / $533,400; MFJ $96,700 / $600,050; HoH $64,750 / $566,700.
The calculator uses the stacking method: your gain is layered on top of your ordinary income to find the marginal rate. This matches how the IRS calculates effective rates on Schedule D.
Not included: state income tax (varies 0–13.3%); Net Investment Income Tax (3.8% surtax for single income > $200k / MFJ > $250k); Self-Employment tax (if mining or staking treated as a trade/business); AMT.
