Bitcoin.Tax vs Dime

Bitcoin.Tax calculates cryptocurrency capital gains, losses, and income, then produces data and tax forms for filing. Its reports include gains, income, donations, Kraken margin trading, and closing balances with net profit or loss and cost basis. Users can import exchange trade histories, spending, income, mining income, and Kraken margin activity, or use CSV imports. Cost-basis methods include FIFO, LIFO, average costing, specific identification, and optional like-kind treatment. The service lists tax-year support for the United States, Canada, Australia, Germany, and the United Kingdom, or a year beginning January 1. It supports DeFi and NFT activity and lists 23 import sources. Tax outputs include IRS Form 8949 PDF, Schedule D, and formats for TurboTax, TaxACT, H&R Block, Drake, and CCH. Free access covers up to 20 trading transactions. Paid plans are billed once per tax year, beginning with Premium at $59.95, paid once for up to 1,000 transactions. The service says margin trading is not completely supported and may produce incorrect values; its terms also say it does not verify that data is accurate or suitable for tax filing.

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.
