Paste your trade history (or a 1099-B). We replay it FIFO and flag which losses are disallowed by the wash-sale rule — including the cross-ticker traps (sell VOO, buy IVV) and across-account repurchases a single-broker tool never checks. This is the backward-looking "are my realized losses actually valid?" check. Free, instant, no login.

INDYXQUANT links every brokerage you own — plus a spouse's IRA — and flags these wash-sale traps automatically, year-round, then exports an IRS-ready Form 8949. The wash hiding across your accounts is invisible to single-broker tools.
Start your free 30-day trial →Educational tool, not tax advice. The IRS has not published a bright-line test for “substantially identical,” so cross-ticker flags (e.g. VOO↔IVV) are cautions to verify with your CPA, not rulings. Loss figures use FIFO cost-basis on the data you paste and may differ from your broker's lot accounting. Nothing you enter is saved.
