VAT Registration Requirements: 2026 Update on Late Registration and HMRC Letters
VAT registration requirements apply from the date you were first liable, not the date you notice. If you passed £90,000 months ago or HMRC has written to you, you owe VAT on fares since your effective date, and telling HMRC first can bring a penalty down to nil.
Published 6 November 2026 · Updated 6 November 2026
If you have passed the £90,000 threshold without registering, the VAT registration requirements do not wait for you to catch up. HM Revenue and Customs (HMRC) registers you from the date you should have been registered, and value added tax (VAT) is due on your takings from that date. The penalty, though, depends heavily on whether you tell HMRC before it tells you.
This 2026 update is for drivers who have just realised they crossed the line months ago, or who have opened an HMRC letter asking about possible VAT registration. It covers how your effective date is fixed, how VAT on past fares is worked out, the current penalty rules, how to disclose and how to reply on time. If you have not crossed the threshold yet, our complete guide to the VAT registration threshold is the better place to start.
Key takeaways
- Missing the VAT registration requirements does not move your start date. HMRC registers you from the date you were first liable, so VAT is due on fares from then.
- Past fares are normally treated as VAT-inclusive, so the VAT due is one-sixth of the fare, not 20% added on top.
- The penalty for failing to notify depends on behaviour and disclosure. Telling HMRC first can bring a non-deliberate penalty to nil, while a prompted disclosure starts at 10%.
- An HMRC letter about VAT is not proof you must register. Test your own taxable turnover, then reply or register promptly.
- Whether your app operator acts as your agent or as principal changes what counts as your turnover, and a further change is planned from 2 January 2028.
What are VAT registration requirements?
VAT registration requirements are the legal tests that decide when a business must register for VAT. You must register if your taxable turnover for the last 12 months goes over £90,000, or if you expect it to go over £90,000 in the next 30 days alone.
According to HMRC's VAT Notice 700/1, Who should register for VAT, these are the historic test and the future test, checked at the end of every month in the 2026/27 tax year as in any other. Taxable turnover includes zero-rated sales but leaves out exempt income. For a driver it is broadly your takings before expenses, not your profit, which is why many drivers are closer to the line than their take-home pay suggests.
What happens if you passed the £90,000 threshold months ago?
HMRC will register you from the date you should have been registered, however late you tell it. You then owe VAT on your taxable takings from that effective date, even though you never charged it. You may also face a failure to notify penalty, and interest may be charged on VAT paid late.
On late cases the VAT registration requirements are blunt. Section 4.6 of Notice 700/1 says HMRC will register you from the date you were liable, whenever you let it know. The longer the gap, the larger the bill, because every month of fares since your effective date carries VAT. Waiting does not shrink the liability. It only makes it more likely that HMRC finds you first.
How your effective date of registration is fixed
Under the historic test, the effective date of registration is the first day of the second month after the month in which you went over £90,000. You have 30 days from the end of that month to tell HMRC. Under the future test, the effective date is the date you realised you would go over the threshold in the next 30 days.
Get this date right before you apply. Some drivers enter the day they finally applied, which understates the VAT due. HMRC's staff guidance on belated notification, at VATREG26550 in the VAT Registration Manual, tells officers to correct the effective date to an earlier date where a trader has been registered from the wrong one.
How is VAT on past fares worked out?
Fares from your effective date are normally treated as VAT-inclusive, because you did not add VAT to them. At the 20% standard rate, the VAT inside a VAT-inclusive amount is one-sixth, so £6,000 of fares contains £1,000 of VAT. You then deduct allowable input VAT on your business costs.
The same VATREG26550 page tells officers to treat the price charged as tax-inclusive unless tax was charged separately. HMRC's VAT guide, Notice 700, sets the VAT fraction at one-sixth for the 20% rate. The difference is real money: adding 20% on top of £60,000 of fares gives £12,000, while the correct VAT-inclusive figure is £10,000. Our VAT calculator splits a gross figure into net and VAT in seconds.
You can also recover some VAT you paid before your effective date. Section 11 of Notice 700 allows VAT on goods bought up to 4 years before registration if you still hold them, and on services received up to 6 months before. Both must relate to your taxable business, and you need acceptable evidence, which in practice means VAT invoices.
Can you go back to passengers for the VAT? In practice, no. Your passengers paid a fare through the app and cannot be traced, and most could not reclaim VAT anyway. The VAT for the late period comes out of money you have already earned, so set it aside the day you spot the problem.
What are the late registration penalties in 2026?
Where the duty to register arose on or after 1 April 2010, late VAT registration falls under HMRC's failure to notify penalty regime. The penalty is a percentage of the potential lost revenue. The rate depends on whether the failure was deliberate and whether you told HMRC before it had reason to find out. The range starts at nil.
Many guides, including some updated this year, still quote bands of 5%, 10% and 15%. Those come from HMRC's Notice 700/41 on late registration penalties, and that notice says it applies where liability to register arose before 1 April 2010. For a driver who crossed £90,000 in 2025 or 2026, the relevant source is HMRC's factsheet CC/FS11, penalties for failure to notify.
| Type of failure | Unprompted disclosure | Prompted disclosure |
|---|---|---|
| Non-deliberate, told HMRC within 12 months of the tax being due | 0% to 30% | 10% to 30% |
| Non-deliberate, told HMRC 12 months or more after the tax was due | 10% to 30% | 20% to 30% |
| Deliberate but not concealed | 20% to 70% | 35% to 70% |
| Deliberate and concealed | 30% to 100% | 50% to 100% |
Where you land inside a range depends on the quality of your disclosure. CC/FS11 explains that HMRC weighs telling it about the failure at up to 30%, helping it work out the figures at up to 40%, and giving access to records at up to 30% of the available reduction. A full, early and accurate disclosure pulls the penalty towards the bottom of the range.
No penalty is due at all if three things are true: you had a reasonable excuse, the failure was not deliberate, and you told HMRC without unreasonable delay once the excuse ended. Not knowing the rules is unlikely to count on its own. The factsheet also gives you, usually, 30 days to challenge a penalty by sending new information, asking for an internal review or appealing to the tribunal. If HMRC is proposing a penalty, get professional representation before you reply.
Prompted or unprompted: why timing matters most
A disclosure is unprompted if you tell HMRC before you have any reason to believe it is about to find the failure. Once a letter or check about your VAT position has arrived, a disclosure is likely to be treated as prompted. For a non-deliberate failure told within 12 months, that lifts the minimum penalty from 0% to 10% of the VAT due.
HMRC has written about VAT registration: what should you do?
Do not ignore it, and do not register on reflex. Check the letter is genuine, then test your own taxable turnover against the VAT registration requirements month by month. If you are over the threshold, register and set out the facts. If you are not, tell HMRC why, keep your workings, and reply by any date the letter gives.
In May 2026 the ICAEW, the chartered accountants' professional body, reported that HMRC was writing to unregistered businesses whose records showed turnover above £90,000. Its Tax Faculty warned that a figure above £90,000 does not always mean registration is required. The figure may cover more than 12 months, or include income that is not taxable turnover. Scam messages about tax are also common, so check any letter against HMRC's guidance on GOV.UK before you call a number or follow a link in it.
Treat the reply as evidence that you understand the VAT registration requirements. Write in plain terms, attach a month-by-month table of your rolling turnover, and keep a copy. If the letter is about your income tax return rather than VAT, the approach in our guide to answering an HMRC enquiry about your mileage claim is more relevant.
| Your position | What it usually means | First move | Watch out for |
|---|---|---|---|
| Rolling 12-month taxable turnover never went over £90,000 | No duty to register | Reply with your monthly totals and a short explanation | Where the operator is your agent, test fares, not bank payouts |
| Over £90,000 once, but the next 12 months will not go over £88,000 | You may qualify for an exception from registration | Apply for an exception promptly, with evidence of falling takings | HMRC decides; if it refuses, you register from the liable date |
| Over £90,000 and HMRC has not contacted you | Liable from your effective date; disclosure can still be unprompted | Register now and disclose the arrears in writing | Every month of delay adds VAT and risks a prompted disclosure |
| Over £90,000 and HMRC has already written | Liable; disclosure is likely to be treated as prompted | Register, reply in writing and give full figures | Higher minimum penalty; accuracy and cooperation still reduce it |
| Unsure because the operator acts as principal | Your turnover may be what you charge the operator, not the passenger fare | Check your driver agreement and take advice | Private or account work still adds to your app turnover |
The exception in the second row comes from Notice 700/1, section 3.7. It applies where you can show your taxable supplies in the next 12 months will not go over the £88,000 deregistration threshold. It is worth asking for if one unusually busy season tipped you over, but you need evidence, not hope.
How do you make a voluntary disclosure of late VAT registration?
For VAT, the practical disclosure route is to register online straight away with your correct effective date, then tell HMRC in writing how and when you went over the threshold and what you owe. HMRC's Digital Disclosure Service is aimed mainly at undeclared income and gains, so check GOV.UK before using it for VAT.
We use the 10-step plan below with drivers who come to us late. It is designed to be finished within 30 days, because speed protects the unprompted position and stops the VAT bill growing.
- Download monthly earnings statements from your driver app for at least the last 24 months, plus records of any private or account work.
- Build a rolling 12-month total at each month end and find the first month it went over £90,000.
- Work out your effective date: the first day of the second month after that month.
- Check whether your operator acted as your agent or as principal on your bookings, because that sets what counts as your turnover.
- Check whether an exception could apply because your next 12 months will not go over £88,000.
- Register for VAT online using the effective date you calculated, following the steps in our VAT registration walkthrough for drivers.
- Write to HMRC with a short disclosure: when you crossed, why you missed it, and your calculation.
- Calculate VAT as one-sixth of fares from the effective date, less input VAT backed by invoices, including allowable pre-registration VAT.
- Set aside the VAT and an allowance for interest, and ask HMRC early about a payment plan if you cannot pay it all at once.
- Diarise the 30-day window to challenge any penalty notice, and keep a copy of everything you send and receive.
How do the 2024 operator VAT changes affect what counts as your turnover?
It depends on whether the operator takes your booking as principal or as your agent. If it acts as your agent, you supply the journey to the passenger, so the fare is broadly your turnover. If it acts as principal, the operator supplies the passenger, and your turnover is broadly what you charge the operator.
The neutral background comes from the government's response to the consultation on VAT treatment of private hire vehicles. A High Court judgment of 6 December 2021 found that London-licensed operators must contract with passengers as principal, and that still stands. A July 2023 High Court ruling extended this elsewhere in England and Wales, but the Court of Appeal overturned it in July 2024, and the Supreme Court upheld that in July 2025.
So, outside London, operators can act as agents. The consultation ran from 18 April to 8 August 2024. The government then chose not to rewrite the agent rules. Instead, it excluded private hire and taxi services from the Tour Operators' Margin Scheme (TOMS) from 2 January 2026, which changes how operators acting as principal account for VAT. It does not change the VAT registration requirements that apply to you as a driver.
The October 2026 update for 2028
On 29 October 2026 the government published a policy paper on the VAT treatment of private hire vehicle operators. From 2 January 2028, journeys supplied through larger operators acting as agent will be deemed to be supplied by the operator, not the driver. The size threshold is still to be consulted on, with £50 million of annual fare turnover as the lead option.
The paper says the measure is unlikely to require more businesses to register, and that some drivers may choose to register voluntarily. It is a proposal awaiting legislation, so treat the detail as subject to change. For a late-registration review, the point is simpler: test each past period under the model that actually applied then. A London driver and a driver in another English city with the same takings can have very different turnover figures.
Read your driver agreement, keep every statement, and take advice rather than assume. Our VAT guide for ride-hailing drivers explains the accounting schemes available once you are registered.
Illustrative example: a driver who spots the problem in September
This illustrative example uses an invented driver, Dev, and our own round figures. Dev drives full time in an English city outside London, where his operator acts as his agent, so his turnover is his gross fares. He takes about £7,800 a month, has no other business income, and knew the VAT registration requirements only in outline.
His rolling 12-month total reaches £90,600 at the end of February 2026. He should have told HMRC by 30 March 2026, and his effective date of registration is 1 April 2026. He notices in early September 2026 while getting ready for Making Tax Digital for Income Tax, which applies from 6 April 2026 where qualifying income is above £50,000.
| Item | Calculation | Amount |
|---|---|---|
| Gross fares, 1 April to 31 August 2026 | 5 months x £7,800 | £39,000 |
| Output VAT, treating fares as VAT-inclusive | £39,000 ÷ 6 | £6,500 |
| Wrong method: 20% added on top | £39,000 x 20% | £7,800 (overstated by £1,300) |
| Input VAT on servicing, tyres, phone and valeting, with VAT invoices | £3,600 ÷ 6 | £600 |
| Pre-registration VAT on a dashcam bought in January 2026 and still held | £180 ÷ 6 | £30 |
| Net VAT due (potential lost revenue) | £6,500 - £600 - £30 | £5,870 |
| Penalty range if he discloses first (non-deliberate, within 12 months) | 0% to 30% of £5,870 | £0 to £1,761 |
| Penalty range if HMRC writes to him first | 10% to 30% of £5,870 | £587 to £1,761 |
Dev registers in September with an effective date of 1 April 2026 and writes to HMRC with his monthly totals. Because he told HMRC before it contacted him, and within 12 months, his penalty range starts at nil. Had he waited for a letter in November, the floor would have been £587, and the VAT bill would have grown by about £1,300 for every extra month of fares.
Nothing here is guaranteed. HMRC sets the final penalty, and interest may also be charged on VAT paid late. But the example shows why the first fortnight after you spot the problem matters more than anything that follows.
Common mistakes and the penalty each triggers
- Registering from today's date instead of your true effective date. HMRC can correct the date, and an understatement that looks deliberate moves you into a much higher penalty range.
- Adding 20% on top of past fares. You overpay VAT and inflate the potential lost revenue that the penalty percentage is applied to.
- Testing bank payouts instead of fares where the operator is your agent. Turnover is understated, the late period grows, and the penalty is worked out on more VAT.
- Ignoring an HMRC letter. Any later disclosure is likely to be prompted, so the minimum non-deliberate penalty rises from 0% to 10%, or to 20% after 12 months.
- Telling HMRC 12 months or more after the VAT was due. Even unprompted, the floor for a non-deliberate failure rises from 0% to 10%.
- Budgeting with the old 5%, 10% and 15% bands. You may set aside too little, because current ranges reach 30% for non-deliberate failures and more for deliberate ones.
- Missing the 30-day window to challenge a penalty notice. You lose the simplest route to a review and may have to rely on a late appeal being accepted.
