Core capability
Most tools treat each exchange as an island. CryptoTax8949 follows lots when you transfer — so one sale on Binance can correctly reflect basis from Coinbase or KuCoin.
See holdings, balances, and activity in one place instead of logging into every platform at tax time.
Identify positions trading below cost basis before year-end so you can offset realized gains within IRS rules.
Every economic event in one auditable timeline — not just buys and sells.
Lots keep their original acquisition price when you move assets between venues.
Workflow
A straightforward path from exchange data to CPA-ready schedules.
Link exchanges via API or upload CSV exports from wallets and platforms you use.
Match withdrawals to deposits so cost basis travels with the asset — across venues.
Apply FIFO, HIFO, LIFO, hybrid rules, or pick specific lots before generating reports.
