10 Legal Ways Taxi Drivers Can Reduce Their Tax Bill

1. Claim Every Genuine Allowable Expense

The simplest tax-saving step is to claim all business expenses you're legally entitled to deduct from your income. Common allowable expenses for taxi and private hire drivers can include fuel, diesel, electricity and charging costs; taxi insurance and breakdown cover; repairs, servicing, tyres and MOT; taxi licence, badge, plate and inspection fees; vehicle cleaning, valeting and cleaning products; Uber, Bolt or FREENOW commission; local taxi-office commission, radio rent and booking fees; phone, data and navigation-app costs used for work; accountancy and bookkeeping fees; business bank charges and card-machine fees; advertising, website costs and taxi-business software; and business parking and toll charges.

HMRC allows self-employed people to deduct eligible vehicle expenses such as fuel, insurance, repairs, servicing, parking, vehicle tax, licence fees and breakdown cover — however, personal travel, fines and penalties cannot normally be claimed. See our full allowable expenses guide for the complete list.

A tax deduction does not mean HMRC refunds the full cost — it reduces your taxable profit, which may reduce the Income Tax and National Insurance you owe. For example:

Calculation	Amount
Taxi income	£45,000
Allowable business expenses	£20,000
Taxable business profit	£25,000

Without claiming the £20,000 of valid costs, your taxable profit would look much higher than it really is.

2. Keep Receipts and Records Throughout the Year

You can only confidently claim expenses when you have good evidence. Save every business receipt, invoice, platform statement and taxi-office settlement record — fuel and charging purchases, vehicle repairs and servicing, insurance payments, licence renewals and badge fees, cleaning and valeting, platform commissions, radio rent or taxi-office fees, phone bills and work-app subscriptions, mileage records, parking and toll receipts, bank charges, and accountancy invoices.

HMRC does not normally require you to submit receipts with your Self Assessment return, but you must keep accurate records and be able to show evidence if HMRC asks. A practical system is to photograph receipts immediately and save them into monthly folders, such as:

Taxi Records
├── April 2026
├── May 2026
├── June 2026
├── Platform Statements
├── Taxi Office Statements
├── Vehicle Costs
└── Licence and Insurance

This avoids missing expenses when you prepare your tax return. See our guide on how to keep tax records as a self-employed driver for a fuller system.

3. Record Gross Fares and Deduct Commission Separately

Uber, Bolt, FREENOW and other platforms often deduct their service fee before paying you. Local taxi offices may also deduct commission, radio rent or booking charges. Don't assume that the money deposited in your bank account is always your complete taxi income figure. For example:

Uber or platform statement	Amount
Gross passenger fares	£1,200
Platform commission	£280
Amount paid to driver	£920

Depending on the contractual arrangement, your records may need to show taxi income of £1,200, a platform commission expense of £280, and a net payment received of £920. The same principle can apply to local taxi-office work — if an office deducts £100 per week in commission or radio rent, keep the statement and record that cost separately. Digital platforms may be required to collect seller information and report income details to HMRC, and must provide the seller with a copy of the reported information. See our Uber vs local taxi office tax guide for more on this distinction.

Accurate records help you reconcile platform figures, taxi-office settlements and bank payments while ensuring you claim the booking fees you've actually paid.

4. Choose Mileage or Actual Vehicle Costs Carefully

For an eligible vehicle, taxi drivers may be able to claim either actual vehicle costs or simplified mileage expenses. The better option depends on your annual mileage, vehicle costs, repairs, insurance, finance, private use and vehicle type.

Actual-cost method

You add up real business vehicle costs, such as fuel or charging, insurance, repairs and servicing, tyres, MOT and taxi tests, vehicle tax, cleaning, breakdown cover, relevant lease or finance costs, and capital allowances where appropriate. If you use the vehicle privately, you must restrict the claim to the business-use percentage.

Mileage method

You keep a clear mileage log and claim the approved mileage rate for qualifying business miles. This method is simpler, but you cannot also claim fuel, repairs, insurance and other vehicle costs that are already covered by the mileage rate. Don't claim both mileage and actual running costs for the same vehicle unless you've confirmed the specific cost is outside the mileage calculation and is allowed — double claiming can lead to an incorrect tax return. See our buying vs leasing a taxi guide for how the vehicle-acquisition method interacts with this choice.

5. Separate Personal and Business Vehicle Use

Many taxi drivers use the same vehicle for work and family life. If that applies to you, don't claim 100% of mixed-use costs without a proper business-use calculation. For example, if your taxi is used 85% for taxi and private hire work and 15% for personal trips, you'd generally restrict relevant actual vehicle costs to the business-use percentage.

The same rule can apply to mobile-phone bills, data packages, broadband, home-office costs, vehicle insurance, repairs, fuel or charging, car cleaning, and leasing and finance costs. HMRC states that you cannot claim non-business use of premises, phones or office resources. Keep a mileage log or make a realistic regular calculation — claiming a fair business proportion is safer than claiming every cost in full.

6. Claim Business Phone, App and Admin Costs

Your phone is often essential for taxi work — Uber, Bolt and other driver apps, booking-office calls, passenger contact, navigation, card-payment systems, digital receipts, insurance and licence administration, bookkeeping software, and email and online banking. You may be able to claim the business proportion of mobile phone bills, data packages, navigation subscriptions, dispatch software, receipt-scanning apps, bookkeeping software, website hosting and domain renewal, and printer ink, stationery and office supplies.

HMRC includes phone, mobile and internet bills, stationery, printing and business software among the types of office costs self-employed people may claim, provided there's a genuine business element. If your phone costs £50 per month and you reasonably use it 70% for work, record the business calculation rather than claiming the full £600 annual bill.

7. Do Not Miss Licence, Insurance and Compliance Costs

Taxi drivers have business expenses that many other sole traders do not. These costs are easy to overlook because they may only be paid once or twice a year. Review whether you've recorded your driver badge and licence renewal, private hire or hackney vehicle licence, plate fees, required medical examinations, DBS-related costs where relevant, local authority vehicle tests, MOT and compliance checks, taxi insurance, public liability insurance, hire-and-reward cover, breakdown membership, taxi signage, meter or card-machine costs, and vehicle camera or safety-equipment costs used for the business.

These expenses can make a meaningful difference to your taxable profit, especially when your licence renewal and insurance payments fall in the same tax year.

8. Consider Pension Contributions as Part of Tax Planning

Paying into a personal pension can help you save for retirement and may provide tax relief — especially useful for drivers who've had a strong year and want to plan their finances before the tax year ends. Tax relief is generally available on private pension contributions up to 100% of your annual earnings, subject to pension rules and the annual allowance. The standard annual allowance is currently £60,000, although lower limits can apply in some situations. If you complete a Self Assessment tax return, additional pension tax relief where relevant is normally claimed through that return.

Don't make a pension contribution purely because someone says it will "wipe out" your tax. Consider your current profit, cash flow, family commitments, existing pension savings, retirement plans, the pension provider's charges, and whether you need independent financial advice. Pension money is normally locked away until the minimum pension age, except in limited circumstances, so make sure the contribution is affordable.

9. Review Your Payments on Account Early

Many taxi drivers receive a shock when their Self Assessment bill includes both tax owed for the previous tax year and the first payment on account towards the next year. Payments on account are usually due on 31 January and 31 July.

If you expect your business profit to be lower than the previous year, you may be able to apply to reduce your payments on account. HMRC allows this where profits or other income have fallen, available tax relief has increased, or more tax has been deducted at source. Only reduce payments on account when you have a realistic reason and calculations to support it — if you reduce them too much, HMRC can charge interest on the shortfall. A simple habit is to put aside a percentage of your weekly taxi profit in a separate tax savings account, rather than spending all income as it arrives.

10. Prepare for Making Tax Digital Before It Becomes Urgent

Making Tax Digital for Income Tax is being introduced in stages, requiring affected self-employed people to keep digital records and send quarterly income and expense updates using compatible software. The rollout timetable is currently:

Start date	Who must use MTD for Income Tax
6 April 2026	Qualifying self-employment and property income over £50,000
6 April 2027	Qualifying income over £30,000
6 April 2028	Qualifying income over £20,000

Qualifying income is generally your gross self-employment and property income before expenses and allowances are deducted. For taxi drivers, this means you should begin keeping digital records now for gross fares, cash fares, app-based income, local taxi-office income, tips and bonuses, Uber or Bolt commission, radio rent and office fees, fuel and charging, vehicle costs, licence fees, and mileage records. Good digital records help you avoid missed expenses, understand your profit each month and make your Self Assessment or Making Tax Digital reporting much less stressful.

The aim is not to pay zero tax. The aim is to pay the correct amount of tax after claiming every legitimate expense and relief available to you.
