The record

Purpose: Dime calculates cryptoasset taxes in the UK from a spreadsheet of transactions and returns tax figures by tax year.
Intended user: The maker primarily intends Dime for people familiar with UK cryptoasset tax rules who want a privacy-preserving way to complete their tax return.
Input format: Dime accepts a transaction spreadsheet in CSV format with fields including date, operation, market value, assets, quantities, fees and income.
Operations: The accepted transaction operations are receive, send, swap and transfer.
Tax year review: After processing a spreadsheet, users can review tax figures for available tax years and see their current fiat balance.
NFTs: The spreadsheet format supports marking sent and received assets as non-fungible, and the guide explains how to report an NFT minted from multiple NFTs.
Privacy: Dime processes transactions locally and stores them with computed tax figures in a SQLite database in the user's .dime folder.
Install options: The project documents installation through Composer, a PHAR archive, Docker and an experimental standalone application.
System requirements: Composer and PHAR installations require PHP 8.2 and the BCMath extension; Docker installation requires Docker and sh or Bash.
Support: The maker says they will try to address bugs and issues related to reported figures, but do not take feature requests; discussion replies are not guaranteed.
Limitations: The maker says the tax figures are only as accurate as the spreadsheet and advises consulting a professional accountant before use.
