Our take
Bitcoin.Tax
Bitcoin.Tax serves as an established, utility-focused tax preparation platform tailored specifically to digital asset transactions. Instead of serving as a brokerage or execution venue, it processes historical transaction records to determine taxable events, capital gains, capital losses, and income generated across centralized trading desks and self-hosted addresses. Its core strength lies in its customizable tax calculations, which permit users to apply specific accounting rules across varied tax jurisdictions.
While modern alternatives emphasize automated onchain tracking for decentralized finance, Bitcoin.Tax retains a clear focus on structured data handling, custom CSV ingestion, and straightforward form generation. Filers who maintain organized records or work directly with accountants benefit from its granular cost-basis options and reliable report exports, making it a functional accounting resource despite a utilitarian user interface.
Koinly
Koinly delivers a comprehensive tax calculation and portfolio management solution designed to handle messy crypto transaction histories. By connecting read-only API keys, public wallet addresses, and CSV records, the platform consolidates activity across centralized trading venues, self-custody addresses, and smart contract protocols. The core strength rests in its extensive regional compliance settings, which support country-specific accounting methods such as FIFO, LIFO, and share pooling rules in the United Kingdom or average cost basis in Canada.
While the service offers free transaction syncing and balance monitoring, downloading official tax filing forms requires an annual tax year license. Pricing scales by total transaction count, which can become costly for automated bot traders or active yield farmers. For individuals seeking clear tax liability calculations and downloadable reporting forms, Koinly provides an established and reliable operational setup.
