Five spreadsheets

Each one built for one job, and honest about who it's for.

All five are Excel files that also work in LibreOffice, with no macros. The two tax sheets, Sole Trader Bookkeeping and the Director calculator, carry the 2025/26 and 2026/27 rates; the others work for any year.

Sole traders and the self-employed

Sole Trader Bookkeeping

FOR: UK self-employed sole traders (cash basis). TAX YEARS: 2025/26 and 2026/27, chosen in Settings. Not for 2024/25 or earlier.
