Dime vs Summ

Dime is a free, open-source command-line tool that calculates United Kingdom cryptoasset taxes from a transaction spreadsheet. It accepts CSV data containing fields such as dates, operations, market values, assets, quantities, fees, and income, with receive, send, swap, and transfer operations. After processing, users can review figures for available tax years and see their current fiat balance. The format supports marking sent and received assets as non-fungible, including guidance for an NFT minted from multiple NFTs. Dime runs locally and stores transactions and computed figures in a SQLite database inside the user’s .dime folder. Installation documentation covers Composer, a PHAR archive, Docker, and an experimental standalone application. Composer and PHAR installations require PHP 8.2 and BCMath; Docker requires Docker and sh or Bash. The project targets people familiar with UK tax rules who want local processing.

Summ is a web service for identifying, organizing, and tracking cryptocurrency activity while preparing tax reports. It combines portfolio value, profit and loss, and tax liability in one place. Reports include summaries, capital gains, income, expenses, audits, and nine other detailed formats, with settings that can be customized for local tax rules. Summ describes a Least Tax First Out method that selects the asset lot with the highest cost basis when a disposal occurs. The service lists more than 3,500 integrations across exchanges, DeFi services, protocols, and wallets, with custom CSV upload when an integration is unavailable. DeFi and NFT support are included. Signup provides transaction importing, smart suggestions, automatic categorization, portfolio tracking, and DeFi and NFT features free; reports and some tools require a paid plan. Summ supports up to one million transactions and offers custom solutions for high-volume traders. It is web-only and headquartered in Sydney, Australia.
