A specialized tax tool that connects directly to brokerage accounts (Schwab, Webull, etc.), automatically imports and validates 1099-B data, flags common errors like incorrect loss netting, and walks users through capital gains optimization strategies such as tax loss harvesting. It cross-references federal and state rules to correctly handle exemptions like US Treasury capital gains and provides a clear audit trail showing exactly how each gain/loss is calculated.

Retail investing has surged with commission-free trading platforms, dramatically increasing the number of individual filers with complex capital gains situations. Meanwhile, mainstream tax software continues to mishandle edge cases, creating a growing gap between user needs and existing tool capabilities.
