TaxMate UK dashboard with income, expenses and an income-versus-expenses chart (demo data)
Dashboard with demo records.

The problem

Sole traders need a simple way to see income received, money still owed and expenses in the right tax year.

Who it is for

UK sole traders and freelancers.

What was built

A responsive web app that separates received, invoiced, outstanding and overdue income, scopes figures to the 6 April tax year, and exports backups as JSON or CSV.

Key features

  • Income and expense records
  • Tax-year-aware dashboard
  • Outstanding and overdue invoice tracking
  • JSON and CSV backup
  • Accessible dialogs and forms

Results so far

Calculations covered by unit tests; workflows covered by end-to-end tests in CI.

Limitations and context

  • Prototype: data is stored only in the browser, with no account or backup service.
  • UK tax rules are not yet implemented; not for filing decisions or tax advice.
