⚡ CalcWolf Insight

The crypto wash sale loophole (as of 2025) is one of the most powerful tax strategies available. You can sell crypto at a loss to offset gains, then immediately rebuy the same coin — locking in the tax loss without actually exiting your position. With stocks, you must wait 30 days to rebuy. Congress has proposed closing this loophole, so use it while it lasts.
