How to use Wash Sale Tracker

  1. Log your buy and sell transactions for a security, including dates.
  2. The tool flags trades that fall within the IRS's 30-day wash sale window (30 days before or after a loss sale), where the loss would be disallowed for tax purposes.

Limitations

  • This flags likely wash sales based on the dates and tickers you enter — it doesn't have visibility into your full brokerage history or substantially identical securities across multiple accounts. Cross-check against your broker's official 1099-B before filing.
