BittyTax vs Koinly
Side-by-side comparison of features, pricing, ratings, and alternatives.
BittyTax is a free, open‑source crypto‑currency tax calculator that helps users import transaction data from a wide range of wallets, exchanges, and blockchain explorers. It supports migration from other crypto tax platforms, making the transition to BittyTax seamless. The tool generates tax reports compatible with major tax authorities and provides detailed breakdowns of gains, losses, and income, enabling individuals and small businesses to stay compliant with minimal effort.
Koinly is crypto tax and portfolio tracking software that imports transaction history from exchanges, wallets, and blockchains, then calculates capital gains, income, and taxes owed. It supports multiple cost-basis methods including FIFO, LIFO, HIFO, and country-specific rules like UK Share Pooling, and it automatically matches transfers between a user's own wallets within a 12-hour window to avoid mistakenly taxing them as sales. The free plan allows unlimited transaction imports and full portfolio tracking, but generating downloadable tax reports such as IRS Form 8949 requires a paid plan, priced from $49 to $279 per tax year depending on transaction volume. Koinly produces localized tax reports for more than 100 countries and integrates with tax filing tools such as TurboTax and TaxAct.
