Self-employed drivers: vehicle leasing, fuel cards, and staying compliant with MTD

For a self-employed driver, the vehicle is central to earning a living. That does not mean every payment connected with it receives the same tax treatment. Lease rentals, loan repayments, fuel card settlements and private mileage each need a clear place in the records.

Making Tax Digital is more manageable once those distinctions are settled. The starting point is the work you actually do and the vehicle you use, including whether it is an ordinary car, a goods vehicle or a specially designed commercial car.

When Making Tax Digital applies

Making Tax Digital for Income Tax changes how qualifying sole traders and landlords keep records and report income. Under HMRC’s timetable, the starting points are:

• From 6 April 2026, if qualifying income exceeded £50,000 in 2024–25.
• From 6 April 2027, if qualifying income exceeded £30,000 in 2025–26.
• From 6 April 2028, if qualifying income exceeded £20,000 in 2026–27.

Qualifying income generally means gross self-employment and property income combined, before expenses. Salary, pension income and dividends do not count towards this particular test. Check HMRC’s qualifying income guidance, including the treatment of VAT and shorter accounting periods where relevant.

The test uses the relevant earlier tax year; passing a figure during a busy month does not mean you join that day. Exemptions can apply. These rules concern your individual business and property income, rather than a limited company’s Corporation Tax reporting.

Establish your own business income

Use your contract to identify what you earn from bookings or transport work. If an operator collects your fees and deducts commission, normally record your gross earnings and the charge separately. If it buys your services for an agreed amount and resells a package, its full customer price is not automatically your turnover.

Keep remittance statements and match them to bank receipts. Payments described as fuel support, waiting time or cancellation fees also need considering according to their purpose. Owner funding and borrowing should remain distinct from customer income.

Leasing, hire purchase and borrowing

An ordinary vehicle lease generally involves rental charges. Hire purchase is an acquisition arrangement that needs different treatment, while an ordinary loan funds an asset purchase. The capital repaid on that loan is not a second expense in addition to the asset’s cost.

Cars have particular rules. Even under the cash basis, buying a car normally requires capital allowances rather than an immediate equipment expense. Cars are excluded from the annual investment allowance.

The car rental restriction

Section 48 of the Income Tax (Trading and Other Income) Act 2005 can restrict car hire deductions. HMRC’s scope guidance explains the emissions threshold and exceptions, and its calculation guidance explains the 15% reduction.

For a current ordinary car lease, emissions above 50g/km generally bring the restriction into consideration. Contract details and exceptions matter, so check the actual agreement and vehicle information. Private use requires its own adjustment as well.

Worked example: a restricted car lease

Imran uses an ordinary leased car with 80% business use. Annual rentals are £6,000. Assume the 15% restriction applies, there are no relevant exceptions, and the example excludes VAT complications.

Other eligible running costs need their own business-use calculation. The £4,080 is a deduction from profit, not a refund of that amount. A different vehicle or contract can change the result.

Can you use mileage instead?

The simplified mileage rules exclude cars designed for commercial use, including black cabs, hackney carriages and dual-control driving instructors’ cars. Do not assume every professional driving vehicle qualifies.

For eligible cars and goods vehicles, the 2026–27 rates are 55p for the first 10,000 business miles and 25p thereafter. Previous vehicle deductions can prevent using the method, and once chosen it normally continues while the vehicle is used in the business.

Mileage covers the relevant vehicle purchase and running costs. You cannot also deduct the same lease, fuel, insurance and repair costs. Business parking and other qualifying travel costs may be separate.

Fuel cards, valeting and other running expenses

With actual costs, retain fuel card purchase records, fee invoices and settlement statements. The fuel purchase and the payment clearing the card account are not two expenses. Reconcile credits and refunds, including disputed transactions.

Business valeting, appropriate insurance, tracking subscriptions and eligible licence renewals may also be relevant. A medical examination or qualification cost needs assessing by its connection with the existing trade and the nature of the expenditure; it is not automatically deductible simply because it supports an application.

HMRC’s travel expenses guidance distinguishes business costs from private travel and fines. Road-use charges incurred for business can differ from penalties for breaking rules. Keep evidence rather than grouping every motoring debit into one allowable total.

Make private use visible

Record total mileage and qualifying business journeys. Include enough detail to explain the route’s purpose, and assess ordinary home-to-work travel on your working pattern. A business account does not convert personal journeys into business mileage.

Avona AI can support categorisation, while your mileage log and finance documents establish the necessary adjustments. Review the vehicle method before replacing the car so the new records start correctly.

A manageable quarterly routine

For a business using standard tax-year periods, the 2026–27 quarterly update deadlines are 7 August 2026, 7 November 2026, 7 February 2027 and 7 May 2027. Updates are cumulative: each covers the tax year so far. Calendar update periods are also available, with the same deadlines.

Keep digital income and expense records, reconcile them regularly and send the required totals through compatible software. The Income Tax (Digital Obligations) Regulations 2026 underpin the requirements; HMRC’s digital record-keeping notice explains the applicable directions. A bank feed needs supporting detail wherever a payment conceals fees, private purchases or several transactions.

Normally, record the transaction date, amount and relevant category, retaining supporting invoices or receipts. HMRC’s digital records guidance explains permitted simplifications and digital links where more than one software product is used.

Quarterly updates do not replace the annual tax return. The 2026–27 return is due by 31 January 2028, and normal tax payment dates continue. HMRC is not applying late quarterly update penalties for 2026–27, but digital records and updates are still required. That first-year approach does not waive other filing or payment obligations.

Settle the vehicle treatment early

Clear agreements and consistent records make reporting easier throughout the year. Avona.app costs £15/month. For help with vehicle deductions and ongoing accounts, Avona Concierge is managed by chartered accountants and starts from £60/month.
