Migliaccio & Rathod LLP is investigating whether popular crypto tax software miscalculated users’ returns under new IRS cost-basis rules effective in 2025.
Tax Software Errors Under New 2025 IRS Crypto Rules
Beginning January 2025, the IRS required wallet-by-wallet tracking of crypto purchases and sales. Users of leading tax apps—like Koinly, CoinTracker, and Crypto-Tax-Calculator—report serious errors, including incorrect fees, phantom negative balances, and tax results off by 20% compared to manual calculations.
Why Faulty Tax Software Is a Legal Concern
Consumers rely on tax software to accurately prepare returns. Incorrect calculations can lead to IRS penalties, costly amended filings, and lost trust. It’s no different than TurboTax misreporting your income and leaving you with fines.

- You used crypto tax software to prepare your 2024 or 2025 returns
