🔑 Key Rule
Driving a minicab under a private hire licence almost always means you're self-employed for tax purposes — even if you work exclusively through one firm or app. That means you're responsible for registering with HMRC, keeping records, and filing your own Self Assessment return.
Do You Need to Register for Self Assessment as a Minicab Driver?
If you earn more than £1,000 a year (before expenses) from driving — whether through a local minicab firm, a radio circuit, or an app — you must register for Self Assessment. Registration deadline is 5 October following the end of the tax year in which you started driving (e.g. if you started in August 2025, you must register by 5 October 2026).
PHV Licence vs Employment Status: Are You Really Self-Employed?
Holding a private hire vehicle (PHV) driver's licence and a vehicle licence from your local council is a strong indicator of self-employment — you take on the financial risk of the vehicle, fuel, and insurance, and you're free to choose your own hours and which jobs to accept. Most minicab firms engage drivers on a self-employed, "owner-driver" basis. If in doubt, HMRC's Check Employment Status for Tax (CEST) tool can confirm your status.
Step-by-Step: Filing Your Minicab Driver Tax Return
Once registered, you'll complete the main SA100 form plus the SA103S (short self-employment) supplementary pages — or the SA103F (full) pages if your turnover exceeds £85,000.
What Income Counts
You must declare all income from your minicab work, including:
- Cash fares paid directly by passengers
- Account/corporate account work invoiced through your circuit or firm
- App-based bookings (Uber, Bolt, FreeNow, local apps) — declare the gross fare before any commission is deducted
- Tips received, where significant and regular
Many minicab drivers earn from a mix of cash jobs, circuit account work, and app bookings — keep a simple weekly log totalling each income stream so nothing is missed at year-end.

What Can a Minicab Driver Claim? Full Checklist
Reducing your taxable profit through legitimate expenses is the single biggest lever you control. Here's what minicab and private hire drivers can claim for 2025/26.
Vehicle Costs: Mileage vs Actual Costs
As with all self-employed drivers, you choose between the HMRC mileage allowance (45p/mile for the first 10,000 business miles, then 25p/mile) or the actual costs method (fuel, insurance, servicing, repairs, apportioned for business use). Most minicab drivers covering high annual mileage find the mileage allowance simpler and more generous — see our HMRC mileage allowance guide for full worked examples.
Licensing, Badges & Council Fees
These are unique to minicab/PHV work and 100% deductible:
- Private hire driver's licence (badge) fee — paid to your local licensing authority
- Private hire vehicle (PHV) licence fee for your car
- Vehicle livery, signage, or roof sign required by your licence
- DBS check and medical examination fees required for licence renewal
- Knowledge test or topographical test fees (where applicable)
Insurance, Radio/Dispatch Fees, Phone & Data
- Hire-and-reward (commercial) insurance — the higher premium required for carrying fee-paying passengers is fully deductible
- Radio circuit / dispatch membership fees — weekly or monthly fees paid to your minicab firm for jobs and dispatch access
- Two-way radio or in-car terminal rental
- Mobile phone and data — the business-use percentage of your bill, essential for apps and dispatch
- Vehicle cleaning and valeting — keeping your car presentable for passengers

⚠ Watch Out For
Declaring net app payouts instead of gross fares (and forgetting to claim the commission as an expense); forgetting cash jobs entirely; missing licence renewal and DBS fees because they're paid annually rather than monthly; and claiming both the mileage allowance and fuel receipts for the same vehicle, which HMRC does not permit.
Worked Example: A Minicab Driver's Tax Bill Calculation
Consider a minicab driver earning £32,000 in gross fares over 2025/26, driving 18,000 business miles:
| Item | Amount |
|---|---|
| Gross fares (cash + account + app) | £32,000 |
| Mileage allowance: 10,000 × 45p + 8,000 × 25p | −£6,500 |
| Licensing, badge & DBS fees | −£450 |
| Radio circuit/dispatch fees (£25/week) | −£1,300 |
| Insurance (hire-and-reward, business portion) | −£900 |
| Phone & data (business portion) | −£300 |
| Taxable profit | £22,550 |
Income Tax and Class 4 National Insurance are then calculated on this £22,550 profit, after deducting your Personal Allowance. Use our free calculator to get your exact figures, including Class 4 NI — see our Class 4 National Insurance guide for how this is worked out.
