Complete Expenses Guide for UK Taxi Drivers
Every pound you claim in legitimate expenses reduces your taxable profit. Most taxi drivers miss deductions worth hundreds of pounds each year. This guide covers all 14 HMRC-approved expense categories for self-employed drivers, what receipts you need, and how to keep digital records that satisfy HMRC.
Why Tracking Expenses Matters
As a self-employed taxi or private hire driver, you pay Income Tax and Class 4 National Insurance on your profit -- not your gross income. Your profit is calculated as gross income minus allowable expenses minus mileage allowance.
This means every legitimate expense you track directly reduces the amount of tax you owe. A driver in the basic rate band saves 26p in tax and NIC for every pound of expenses claimed (20% Income Tax + 6% Class 4 NIC).
Quick example
If you spend £3,000 per year on fuel but forget to claim it, you are overpaying tax by approximately £780(at the basic rate). Over five years that is £3,900 gone unnecessarily.

HMRC-Approved
The 14 Expense Categories for Taxi Drivers
HMRC allows self-employed taxi drivers to deduct expenses that are "wholly and exclusively" for business purposes. Here are all 14 categories Fyled tracks for you, with guidance on what qualifies.
Fuel
Petrol, diesel, electricity for your vehicle. Keep every fuel receipt and note the date, amount, and litres purchased. If you use your vehicle for both personal and business, you can only claim the business proportion.
Repairs & Maintenance
MOT, servicing, tyres, brakes, exhaust work, and any mechanical repairs to your taxi. Bodywork repairs from accidents on shift also qualify. Keep the garage invoice.
Insurance
Taxi or private hire insurance premiums. This includes your commercial vehicle policy and any public liability insurance required by your local authority.
Road Tax (VED)
Vehicle Excise Duty for your taxi. The full cost is deductible if the vehicle is used exclusively for business. For mixed use, claim the business proportion.
Licence Fees
Your taxi or private hire driver licence, vehicle licence, and any council licensing fees. DBS check costs for licence renewals also qualify.
Cleaning & Valeting
Car washes, interior valeting, air fresheners, and cleaning supplies for your cab. Passengers expect a clean vehicle, and HMRC recognises this as a legitimate business cost.
Phone & Data
Your mobile phone contract or top-ups used for ride-hailing apps, sat nav, and communicating with passengers. Claim the business proportion of your phone bill.
Parking & Tolls
Parking fees at ranks, airports, and stations. Congestion charges, toll roads (Dartford Crossing, M6 Toll), and any clean air zone charges during working hours.
Vehicle Finance
Interest on a hire purchase or loan for your taxi. Note: you cannot claim the capital repayment, only the interest portion. Lease payments are fully deductible.
Accountancy Fees
Fees paid to an accountant or tax software (like Fyled!) for preparing your Self Assessment. Bookkeeping services and tax advice also count.
Advertising
Business cards, vehicle signage, decals, online listings, and any marketing to attract passengers. If you advertise your private hire service, the full cost is deductible.
Bank Charges
Fees on your business bank account, card payment processing fees (e.g. SumUp, iZettle terminal charges), and overdraft interest on your business account.
Training
Courses to maintain or improve your driving skills, NVQ in road passenger transport, disability awareness training, or safeguarding courses required by your council.
Other Expenses
Anything else wholly and exclusively for your taxi business: sat nav subscriptions, dash cam purchases, first aid kit, high-vis vest, uniform costs, or trade union fees.
What Receipts Do You Need?
HMRC requires you to keep records of all business income and expenses for at least five years after the 31 January submission deadline for that tax year. You do not need to send receipts with your tax return, but you must be able to produce them if HMRC asks.
What counts as a receipt?
- Till receipts from petrol stations, garages, and shops
- Invoices from mechanics, insurance companies, and suppliers
- Bank statements showing direct debits and card payments
- Digital receipts from email or apps (Uber, Bolt, etc.)
- Mileage log with dates, start/end readings, and purpose
Common mistakes to avoid
- Claiming personal expenses as business costs
- Not splitting mixed-use costs (e.g. phone used 50/50 personal and business)
- Claiming both mileage allowance AND fuel/repair costs (you must choose one method)
- Throwing away receipts before the 5-year retention period ends
Digital Record Keeping
Under Making Tax Digital (MTD), HMRC now accepts -- and increasingly requires -- digital records. Paper shoeboxes full of receipts are a thing of the past. Digital records are searchable, cannot fade like thermal paper, and are automatically backed up.
Benefits of going digital
- Receipts are stored securely in the cloud -- never lost
- Automatic categorisation saves hours of bookkeeping
- Totals update in real time as you add expenses
- Export-ready reports for your accountant or HMRC
- Compliant with MTD for Income Tax requirements
WhatsApp Receipt Scanning with Fyled
With Fyled's Standard and Premium plans, you can snap a photo of any receipt and send it via WhatsApp. Our AI reads the amount, date, and vendor, then auto-categorises it into the right expense category. No typing, no manual entry, no forgotten receipts at the bottom of your glovebox.
Mileage Allowance vs. Actual Costs
HMRC gives you two methods to claim vehicle costs. You must pick one and stick with it for that vehicle.
Mileage Allowance (Simplified)
Claim 45p per mile for the first 10,000 business miles and 25p per mile thereafter. You cannot claim fuel, repairs, insurance, or road tax separately under this method -- the mileage rate covers everything.
Best for: Drivers with lower vehicle costs or who want simplicity.
Actual Costs Method
Claim the actual amount you spend on fuel, repairs, insurance, road tax, and all other vehicle costs. You must keep receipts for everything and calculate the business-use proportion if the vehicle is also used personally.
Best for: Drivers with high running costs or expensive vehicles.

Top Tips for Managing Your Expenses
Record expenses the same day
The longer you wait, the more likely you are to lose a receipt or forget a cost. Get in the habit of logging expenses at the end of every shift.
Separate business and personal spending
Use a dedicated business bank account or card. This makes it much easier to identify and evidence business expenses if HMRC enquires.
Photograph every paper receipt immediately
Thermal till receipts fade within months. Take a photo or use Fyled's WhatsApp scanning feature to create a permanent digital copy.
Review your expenses monthly
A quick monthly review helps you spot missing categories. Many drivers forget to claim phone bills, parking, or cleaning costs.
Use software designed for drivers
Generic accounting software is not built for taxi drivers. Fyled knows your 14 expense categories, calculates mileage allowance, and prepares HMRC-ready reports automatically.
