Lock Periods lets you freeze past tax years while safely optimizing current ones. Lock historical data, experiment with accounting methods, and improve tax outcomes without risking previously filed reports.

Summ now supports Aster DEX and the Sei network, making it easier to import perpetual, spot, and on-chain transactions for accurate crypto tax reporting. Connect via API, wallet address, or CSV to simplify your crypto tax calculations and reduce manual tracking.

Our new spam center gives you control over any crypto spam currencies that slip through automated detection. Mark entire currencies as spam in one click, manage all spam controls centrally, and maintain clean transaction data for precise reports.
