Connecticut Crypto Tax Calculator
Estimate your 2025 federal and Connecticut state tax on crypto capital gains, with FIFO, LIFO, or HIFO cost basis.
Crypto capital-gains tax in Connecticut
Connecticut has seven brackets from 2% to 6.99% for 2025; the bottom two rates were cut to 2% and 4.5% starting in 2024 and are unchanged for 2025. The state has no standard deduction, and its personal exemption phases out so steeply with income that it is not modeled here. Rate-recapture provisions for very high earners are also excluded from this estimate.
