About CabTax
Built for UK taxi drivers
CabTax is a Self Assessment and tax-return app built for UK taxi and private hire drivers. We help you log income and expenses with taxi-specific categories, track business mileage at HMRC rates, see a live estimate of your Income Tax and National Insurance, and prepare your SA100 figures in one place.
Who CabTax is for
CabTax is designed for self-employed taxi, private hire, Uber and Bolt drivers who complete a Self Assessment. It can also suit other sole traders with straightforward tax affairs. If your situation is complex, we recommend speaking to a qualified accountant.
It is available in five languages — English, Urdu, Punjabi, Bengali and Somali — so you can manage your return in the language you know best.
What CabTax does
  • Log income from apps, private jobs, cash, PAYE, dividends, interest, rental and capital gains
  • 28 taxi-specific expense categories
  • Mileage tracking at HMRC simplified rates (55p then 25p per mile)
  • Live Income Tax and National Insurance estimate
  • Making Tax Digital quarterly updates sent to HMRC
  • SA100 summary export as PDF or CSV
CabTax connects to HMRC's official Making Tax Digital system for quarterly updates. For the annual SA100 Self Assessment, CabTax produces a summary you submit yourself. CabTax is working towards recognised software status and is not yet listed on HMRC's approved software list.
