Costs that may be allowable
These are common examples. A cost is allowable only if it is wholly and exclusively for your business, so check GOV.UK guidance on expenses if you are self-employed, or ask an accountant.
- Licensing fees may be allowable
- Vehicle costs or mileage may be allowable
- Insurance may be allowable
- Radio fees may be allowable
- App fees may be allowable
- Vehicle cleaning may be allowable
Common mistakes
- Not retaining receipts or invoices for taxi licence fees.
- Mixing business and personal journeys in one mileage record.
- Using both simplified mileage and actual vehicle costs for the same vehicle.
- Leaving app or radio fee statements apart from fare and vehicle records.
Records worth keeping for this trade
- Taxi licence fee receipts and related correspondence.
- App or radio fee statements alongside fare records.
- Vehicle cost and insurance invoices, with business and personal use recorded separately.
- Mileage log with date, destination, purpose and distance.
How can a taxi driver connect app or radio charges to their driving records? Keep app or radio fee statements with fare records, retain licence and vehicle cost documents, and log business journeys separately from personal travel.
Keep records as you go
Keep receipts, invoices and mileage details as you work, and record business and personal use separately where needed. Organised records make it easier to prepare your Self Assessment return.
