UK Sole Trader Tax & Bookkeeping Tracker

Stop dreading January 31st. This is a UK-specific bookkeeping tracker mapped exactly to HMRC's SA103 self-assessment categories.

What you get:

Income & expense log (with SA103 dropdowns)

Live tax estimate so you know what to set aside

Mileage tracker (45p / 25p rules built in)

Quarterly summary dashboards

Simple instructions, no accounting jargon

Unlike generic US trackers, this is built specifically for the UK self-assessment system. Keep your records clean and hand them to your accountant, or use the totals to file yourself.

Works in Excel, Google Sheets and Apple Numbers. A planning tool, not financial advice. Instant download (XLSX).
