Self Assessment Return for VAT-Registered Drivers: Your Questions Answered

On your Self Assessment return, a VAT-registered driver normally reports turnover and expenses without the VAT that passes through to HMRC. The exceptions are the Flat Rate Scheme, cash basis records kept with VAT included, and the year you register, and each one changes the numbers you type in. This FAQ works through those changes for the 2026/27 tax year, using the box references in HMRC's current notes.

We wrote it for self-employed ride-hailing and private hire drivers who already know they are VAT registered and now want the income tax side right. If you are still deciding whether to register, start with our guide to VAT for ride-hailing drivers. For a pre-filing list of documents and deadlines, use our Self Assessment tax return and VAT checklist instead. This page sticks to one job: how VAT changes the figures on the return itself.

Key takeaways

• VAT you collect for HMRC is not your income, and VAT you reclaim is not your cost, so neither should inflate your Self Assessment return.
• On the Flat Rate Scheme, the VAT you keep (VAT charged minus the flat rate paid) is taxable business income.
• If your cash basis records include VAT, deduct net VAT paid to HMRC as an expense and add net repayments as income, in the tax year the cash moves.
• In the year you register or deregister, figures either side of the date are treated differently, and HMRC asks you to explain the split in box 103.
• A mileage-rate claim is a flat figure with no VAT inside it; any fuel VAT reclaim happens on your VAT return, not your tax return.

What is a Self Assessment return for a VAT-registered driver?

It is the same annual Self Assessment return every self-employed driver files, reporting profit for Income Tax and National Insurance. VAT registration does not create a second tax return. It changes which turnover and expense figures you enter, because the VAT element must either be left out or adjusted for.

Does VAT registration change which self-employment pages I fill in?

Often, yes. HMRC's notes for the 2025 to 2026 return say you must use the 'Self-employment (full)' pages if your turnover was £90,000 or more. A driver who registered because they crossed the £90,000 VAT threshold will usually be at that level, so the short pages no longer fit. Voluntary registrants below that figure may still qualify for the short version.

According to HMRC's Self-employment (full) notes for 2025 to 2026, the full pages are also needed in other cases, such as when your accounting period needs adjusting. Filing software normally asks the questions and picks the right pages for you. The box numbers in this article come from those notes, so check the 2026/27 version when HMRC publishes it, as numbering can move between years.

What turnover figure goes on my return under the standard VAT scheme?

With standard VAT accounting and traditional (accruals) records, enter your fares excluding the output VAT you charged. HMRC's notes say income and deductions would typically exclude VAT unless the VAT is not recoverable. Expenses go in net of any VAT you reclaim, and at their full price where there is nothing to reclaim.

In practice, a fare of £24 that includes £4 of VAT goes into your accounts as £20 of turnover. A £60 valet with £10 of reclaimable VAT goes in as £50. Motor insurance, which is exempt from VAT, goes in at the full premium because no VAT was charged to reclaim.

The VAT account sits outside your profit. Output VAT collected and input VAT reclaimed are netted off on your VAT return, and under this method the balance you pay HMRC is not an expense on your Self Assessment return. Deducting it would relieve the same money twice, because it never entered your turnover in the first place.

How do I enter figures if my records are on the cash basis?

Cash basis records for a VAT-registered business usually include VAT, and HMRC accepts that. Its notes say that if you include VAT, put your net VAT payment to HMRC as an expense in box 30 and any net VAT repayment in box 16. Over time the VAT nets to nil, but timing can shift profit between tax years.

GOV.UK now describes the cash basis as the standard way for sole traders to record income and expenses, so many drivers end up here without consciously choosing it. The catch is timing. A VAT return and payment are usually due one calendar month and seven days after the period ends, so VAT collected in the last quarter of the tax year is often paid in May. Under the VAT-inclusive method, that VAT sits in this year's turnover and is only deducted next year.

Either method gives the same total profit over the life of the business. What differs is which tax year bears it, and that matters in a year when your income crosses a tax band or when you stop trading. Pick one method, apply it to every line, and never mix VAT-inclusive fares with VAT-exclusive costs. Our guide to how bookkeeping feeds every box shows how to set your records up so the choice is obvious at year end.

What about VAT on a cost that is not an allowable expense?

HMRC's notes deal with this directly. If an item is not deductible for Income Tax but the VAT on it is recoverable, add that recoverable VAT to the expense in box 30, or take it off the repayment in box 16, and explain in box 103. Capital allowances are worked out on the cost excluding any recoverable VAT.

This matters if you buy a car. HMRC's motoring expenses guidance (VAT Notice 700/64) allows VAT recovery on a qualifying car intended to be used primarily for hire with a driver to carry passengers, so a VAT-registered private hire driver may be able to reclaim it. Check the conditions with an adviser first. If you use the simplified mileage rate instead, you do not claim the car's cost on your Self Assessment return anyway.

How does the Flat Rate Scheme change my Self Assessment return?

On the Flat Rate Scheme you pay HMRC a fixed percentage of your VAT-inclusive turnover and keep the rest of the VAT you charged. HMRC expects accounts to use gross receipts less the flat rate VAT for turnover, with irrecoverable input VAT kept in expenses. The VAT you keep is therefore taxed as business income.

HMRC's VAT Notice 733 on the Flat Rate Scheme sets out that accounts treatment in section 7.8. According to GOV.UK's page on how much you pay under the Flat Rate Scheme, the rate for 'transport or storage, including couriers, freight, removals and taxis' is 10%, with a 1% reduction in your first year of VAT registration. Limited cost businesses pay 16.5% instead, so test that rule every VAT period.

Some advisers reach the same profit by a different route: net fares first, then a separate line for the gap between VAT charged and flat rate VAT paid. Both routes land on one figure. The version that goes wrong is net fares with no second line, because the scheme's benefit then vanishes from your Self Assessment return and profit is understated.

Why does the first-year discount slightly raise my taxable profit?

The 1% discount means less flat rate VAT goes to HMRC, so more of each fare stays with you. Because turnover on the return is gross receipts less flat rate VAT paid, a smaller payment produces a larger turnover figure. You are still better off overall: the VAT saved is kept in full, while only part of it is lost to Income Tax and National Insurance.

Can I reclaim any VAT on costs while on the Flat Rate Scheme?

Only in narrow cases. VAT Notice 733 (section 15.2) allows a reclaim on a single purchase of capital expenditure goods costing £2,000 or more including VAT, but not on services or smaller items. If you make that reclaim, leave the reclaimed VAT out of the asset's cost for capital allowances. Everyday costs stay in your accounts at their VAT-inclusive price.

Standard scheme or Flat Rate Scheme: what lands on the return?

The table below is our own summary of how each approach changes the self-employment pages. It is built from HMRC's 2025 to 2026 notes and VAT Notice 733, and assumes a sole trader driver using the simplified mileage rate.

What happens in the tax year I register for VAT?

The year splits in two. HMRC's notes say expenses up to your registration date should include VAT, because you could not reclaim it then. From the effective date, your chosen VAT method applies. Use box 103, 'Any other information', to give the registration date and say whether you included VAT in income and expenses from that date.

Your effective date comes from the threshold test. GOV.UK's VAT registration guidance says that if taxable turnover over the last 12 months passes £90,000, the effective date is the first day of the second month after you went over. A driver who crossed the line in August would be registered from 1 October, with VAT due on fares from then. Our VAT threshold and personal tax FAQ explains how to track the rolling total.

What about VAT reclaimed on things bought before registration?

HMRC's VAT Input Tax Manual (VIT32000) allows a reclaim on goods bought up to four years before registration if they are still on hand and used in the business, and on services received up to six months before. If you already deducted those costs at their VAT-inclusive price, the VAT you get back is recovered money. Your accountant will either reduce the expense or bring the refund in as income, so you do not get relief twice.

What changes in the year I deregister?

The split runs the other way. HMRC's notes say expenses from the date you cancel your registration will include VAT again. Box 103 should give the deregistration date and say whether income and expenses before that date include VAT. Any final VAT bill or refund still needs placing in the correct tax year.

Deregistering may also mean accounting for VAT on business assets you still hold, such as a car on which VAT was recovered. If that could apply to you, take advice before the cancellation date rather than after it, while there is still time to plan the timing.

Can a VAT refund or VAT bill be counted twice on the return?

Yes, and it is the error we correct most often. It happens when a driver excludes VAT from turnover and also deducts the VAT payment as an expense, or includes VAT in turnover but forgets to deduct what was paid over. Choose one method, then use your bank statements to prove every VAT payment and refund.

How to check the VAT figures on your return, step by step

1. Write down which method you used: VAT excluded, VAT included on the cash basis, or the Flat Rate Scheme.
2. List every VAT return period that overlaps 6 April 2026 to 5 April 2027, with the date each payment left your account or each refund arrived.
3. If VAT is excluded, confirm no VAT payment or refund appears among your expenses or other business income.
4. If VAT is included, total the payments made within the tax year for box 30 and the refunds received for box 16.
5. On the Flat Rate Scheme, confirm turnover equals VAT-inclusive receipts minus flat rate VAT for the same periods.
6. Compare the turnover on your Self Assessment return with the turnover on your VAT returns for the same months, and explain any gap by timing or scheme.
7. Add a short note in box 103 if you registered, deregistered or changed scheme during the year.

Does my mileage claim change once I am VAT registered?

Not on the Self Assessment side. GOV.UK's guidance on simplified expenses for vehicles gives 55p a mile for the first 10,000 business miles and 25p after that for 2026/27, up from 45p before 6 April 2026. You enter business miles multiplied by the rate, with no VAT to strip out.

The rate replaces actual costs such as fuel, insurance, repairs and servicing, and black cabs and hackney carriages cannot use it. Fuel VAT is a separate question for your VAT return under the standard scheme, limited to the fuel element and backed by receipts. Our mileage allowance and VAT FAQ covers that calculation, so we will not repeat it here. On the Flat Rate Scheme there is no fuel VAT to reclaim.

HMRC's simplified expenses guidance does not set out any separate adjustment to the mileage figure where fuel VAT is reclaimed. If you claim both, keep your fuel receipts and workings together and ask your accountant to confirm the treatment for your circumstances.

Is there VAT on ride-hailing fares in the UK?

Taxi and private hire fares are standard-rated when the business supplying the journey is VAT registered. HMRC's VAT Notice 700/25 on taxis and private hire cars says fares are liable at the standard rate and that voluntary tips are outside the scope of VAT. Who the supplier is depends on contracts and working practice.

The notice explains that where an operator acts as principal, it accounts for VAT on the full fare paid by the customer. Where it acts only as an agent, VAT on fares is due only if the driver is VAT registered. That is why two drivers with similar takings can be in different VAT positions. Read your own terms with the app operator, or ask us to, rather than assuming either way.

The rules are due to change. GOV.UK's note on VAT on passenger transport supplied through agents says that from January 2028, journeys booked through an agent will be treated as supplied by the agent, where it is above a set turnover threshold, and the agent then charges VAT on the full fare. If that reaches you, both your VAT and Self Assessment return figures would change from that point.

Illustrative example: one driver, three ways to fill in the return

This illustrative example uses an invented driver and our own round figures for 2026/27. Dev drives private hire full-time as a sole trader and is the supplier of his journeys. His rolling 12-month takings pass £90,000 in August 2026, so his VAT registration takes effect from 1 October 2026. To keep the comparison clean, he makes no fuel VAT reclaim.

• 6 April to 30 September 2026, not registered: fares received £46,000; other costs £2,400 with no VAT to reclaim.
• 1 October 2026 to 5 April 2027, registered: receipts including VAT £50,400, of which output VAT is £8,400 (one-sixth); other costs £2,400, including £240 of reclaimable VAT.
• Business mileage for the year: 30,000 miles, claimed as 10,000 × 55p plus 20,000 × 25p = £10,500.

Option A, standard scheme with VAT excluded: turnover is £46,000 + £42,000 = £88,000. Expenses are £10,500 + £2,400 + £2,160 = £15,060. Profit is £72,940, and Dev pays HMRC £8,160 of VAT (£8,400 less £240) through his VAT returns.

Option B, standard scheme on the cash basis with VAT included: turnover is £46,000 + £50,400 = £96,400, and costs are £15,300. Only his October to December VAT payment, say £4,080, left his account inside the tax year, so that goes in box 30. Profit is £77,020. The other £4,080 is paid after 5 April 2027 and deducted in 2027/28, so Option B moves £4,080 of profit forward a year.

Option C, Flat Rate Scheme at 9% (10% less the first-year 1%), assuming he passes the limited cost business test: flat rate VAT is 9% × £50,400 = £4,536. Turnover is £46,000 + (£50,400 − £4,536) = £91,864. Expenses stay VAT-inclusive at £15,300, giving profit of £76,564.

Compare A and C. On the Flat Rate Scheme, Dev pays £3,624 less VAT (£8,160 − £4,536), and his taxable profit is exactly £3,624 higher (£76,564 − £72,940). The saving is real, but it is taxed. Our VAT calculator helps you test your own figures before choosing a scheme.

What are the common mistakes, and what can they cost?

The usual errors are double counting VAT, leaving the Flat Rate Scheme benefit out, and mixing VAT-inclusive and VAT-exclusive figures. Each one misstates profit. Where tax is underpaid, HMRC charges interest and may charge a penalty for an inaccurate return, so checking before you file costs far less than correcting afterwards.

• VAT-inclusive fares with no VAT payment deducted: profit is overstated, and you overpay tax unless you amend the return.
• Net fares on the Flat Rate Scheme with the VAT kept left out: profit is understated, which can lead to interest on the tax underpaid and possibly a penalty.
• Deducting the VAT payment after already excluding VAT: the same money is relieved twice, with the same exposure to interest and penalties.
• Ignoring the registration date: pre-registration costs entered net of VAT you could never reclaim, which understates your expenses.
• Missing the 31 January online filing deadline while sorting out VAT figures: HMRC can charge late filing penalties, so check our guide to key tax dates for drivers.

Key terms

• Output VAT: the VAT included in the fares you charge, which you owe to HMRC.
• Input VAT: the VAT on business costs, reclaimable under the standard scheme with a valid VAT invoice.
• Flat Rate Scheme: a simplified VAT scheme where you pay a fixed percentage of VAT-inclusive turnover and generally cannot reclaim input VAT.
• Limited cost business: a Flat Rate user whose spending on relevant goods is below HMRC's test, and who must use the 16.5% rate.
• Effective date of registration: the date your VAT registration starts and VAT becomes due on your fares.
• Cash basis: recording income and expenses when money is received or paid, now the standard method for sole traders.
• Box 103: the 'Any other information' box on the full self-employment pages, used to explain VAT changes during the year.

How UK Driver Accountants helps

UK Driver Accountants works only with drivers, on fixed fees from £20 a month, and is independent of any ride-hailing app. Our VAT service for drivers covers registration, scheme choice, quarterly VAT returns under Making Tax Digital (MTD) for VAT, and the reconciliation that makes your Self Assessment return agree with them. See our pricing for what each plan includes.

If you drive through a limited company, the company deals with VAT and your personal return looks quite different. Our guide to the Self Assessment return for limited company director drivers covers that route.

Get your VAT and Self Assessment figures to agree

Being VAT registered does not make your Self Assessment return harder in principle, but it does make the right figures less obvious. Decide your method, apply it consistently, split the registration year properly and explain any change in box 103. If you would like us to check your figures well before 31 January, contact our team and we will review them for a fixed fee.
