Built for UK sole traders, not US software.

Tidy Trader makes one thing well: a plain, honest set of bookkeeping and Self Assessment templates for UK sole traders, freelancers and side-hustlers. No subscription, no login, no fluff.

Why we exist

Most "small business" templates were built for the US and quietly get the UK wrong: wrong tax year, no SA103 boxes, mileage and working-from-home rates that don't match HMRC. We built the pack around the rules you actually file under, cash basis, simplified mileage, the WFH flat rate, and MTD ITSA landing in 2026.

What you can expect

• UK-correct figures for the 2026-27 tax year, kept current if HMRC moves a rate.
• Spreadsheets that open in Excel, Numbers, Google Sheets or LibreOffice.
• A short, plain-English guide, not forty pages of filler.
• One payment, yours to keep, with a 14-day no-questions refund.

What we are not

We are not accountants and the pack is not tax advice. It helps you keep tidy records and see what you will owe. For anything specific to your situation, talk to an accountant or HMRC.
