Summ Reviews

Summ (formerly Crypto Tax Calculator) is especially valued for its industry-leading number of over 2,900 integrations. No other platform in this comparison offers such broad coverage of exchanges, wallets, and blockchains. Support for FIFO, LIFO, HIFO, and ACB as tax methods, along with country-specific tax formats for over 20 countries, makes the tool appealing for internationally active crypto investors.

Particularly noteworthy is the comprehensive Web3 and DeFi support, which also fully captures NFT transactions. The developer API enables advanced use cases and integrations into existing workflows. Prices ranging from 49 to 299 USD per year are considered moderate by market standards and offer tiered options for different portfolio sizes.

A free plan is not currently available, which raises the barrier to entry compared with some competitors. Setup is described as moderately complex, and audit support is still unavailable. Overall, Summ is considered especially suitable for users who use a wide range of exchanges and DeFi protocols and are looking for a tool with maximum integration breadth – especially for users with diversified portfolios across many platforms.
