About this tool

Price the tax on one crypto sale for 2026. The model takes sale proceeds, cost basis, your other income, and filing status, then applies either ordinary federal rates stacked on your other income for short-term sales or the 0, 15, and 20 percent long-term schedule. On the defaults, a 20,000 dollar sale with a 12,000 dollar basis leaves an 8,000 dollar gain; short-term, sitting on 85,000 dollars of other income as a single filer, it adds 1,760 dollars of tax at the 22 percent marginal rate, while the same gain held over a year costs 1,200 dollars at 15 percent. This is a single-lot, federal-only estimate: FIFO lot matching, state tax, and loss carryforward rules are out of scope. Simplified single-lot federal estimate for 2026: no lot matching, no state tax, no loss modeling, no special rate exceptions; verify with official sources; not tax advice.Brokers now report digital asset sales on Form 1099-DA, covering 2025 transactions onward, so proceeds and often basis arrive pre-printed. Losses follow offset rules in real filings: gains cancel losses first, then up to 3,000 dollars reduces ordinary income, with the rest carried forward; enter net positive gains here. The holding clock runs from the day after acquisition to the day of sale.
