VAT for UK Garages: the MOT Trap, Simplified Invoices and What Changes in 2029

Most UK garages charge VAT on the MOT. Many of them do not have to. HMRC’s own guidance says the test fee can sit outside the scope of VAT altogether when you are an authorised centre and you charge up to the statutory maximum — and on a £54.85 test, that difference is yours to keep or to pass on.

That is one of three VAT rules that quietly cost garages money. Here are all three, plus the change the government announced three days ago that every VAT-registered garage will have to plan for.

A VAT invoice has nine things on it. Miss one and your trade customer cannot reclaim.

Parts and labour priced line by line, your VAT number on the document, VAT separate from the net, and the MOT handled separately when it needs to be. From £35/month, one user, up to 100 job cards.

The short version

  • The MOT fee can be outside the scope of VAT when you are an authorised test centre charging up to the statutory maximum. Subcontract it and the rules change — and anything you add on top is taxable.
  • You can issue a simplified invoice up to £250, which is most of a garage’s retail work and a lot less paperwork.
  • A full VAT invoice needs nine specific things. Leave one out and your trade customer cannot reclaim, which is a phone call you do not want.
  • Parts and labour are both standard-rated at 20%. There is no reduced rate hiding in a repair bill.
  • Making Tax Digital has applied to every VAT-registered business since 1 April 2022.
  • From 1 April 2029 you will have to issue and receive e-invoices. The roadmap was published on 28 October 2026. It is not real-time reporting, and it is further away than the headlines suggest — but it decides what you buy now.

The MOT trap

This is the rule most garages get wrong, and it comes straight from HMRC’s VAT guide.

If you are an authorised MOT centre and you do the test yourself, the fee can be treated as outside the scope of VAT, up to the statutory maximum. The caps are £54.85 for Class 4 and £58.60 for Class 7.

If you subcontract the test to another garage, it only stays outside the scope if you pass it on as a disbursement — at cost, with the customer aware that another business carried out the test. Anything you charge above what you paid is your own supply, and that part is taxable at 20%.

Why it matters more than it looks

Take a £54.85 Class 4 test. Treated correctly as outside the scope, the whole £54.85 is the fee. Treated as a standard-rated supply, £9.14 of it is VAT you hand over. Over a year of tests that is a meaningful number, and it is a number you can either keep or use to price under the garage down the road.

The flip side is the one that causes trouble at inspection: if you subcontract and add a £10 handling charge, that £10 is taxable even though the test itself was not. Mixing the two on one line is how it goes wrong. Keep the test fee and anything you add as separate lines.

Worth saying plainly: this is a summary of published guidance, not advice on your business. Check the current position with your accountant before you change how you invoice.

The £250 shortcut most garages ignore

For supplies up to £250, you can issue a simplified VAT invoice rather than the full document. For a garage that is a large share of retail work — a service, a pair of tyres, a diagnostic.

The saving is not the paper. It is the counter. A simplified invoice does not need the customer’s details, which means you are not asking a walk-in for their address while three people queue behind them.

Above £250, or whenever a business customer wants to reclaim, you need the full version.

What a full VAT invoice must show

Nine items. The one garages most often miss is the last one, and it is the one that triggers the call back.

On every full VAT invoice
A sequential number, unique in the series
The tax point (time of supply)
Your name, address and VAT registration number
The customer’s name
A description of the goods or services
Quantity, VAT rate and amount for each line
The unit price
The total excluding VAT
The total VAT, expressed in sterling

Two practical notes. Sequential means no gaps — a cancelled job still burns its number, and a credit note is its own document, not a deletion. And the VAT total has to be in pounds even if you invoiced a fleet in another currency.

Nine items, every time, without checking a list.

Sequential numbering, your VAT number, parts and labour as separate lines, the VAT total in sterling. From £35/month, up to 100 job cards a month.

Estimate and quotation are not the same word

This is not a VAT rule, but it ends up on the same piece of paper and it is the single most common cause of an argument at the counter.

In UK trade practice the two words carry different weight. An estimate is an approximate cost — you may charge more than it, within reason. A quotation is a firm price — you are held to it. The industry code treats them as distinct, and a customer who was given one and billed as though it were the other has a complaint with something behind it.

The practical rule: write down which one you gave, and record the customer’s authorisation when the work grows beyond it. The dispute is almost never about whether you did the job. It is about whether they agreed to it.

Making Tax Digital

Every VAT-registered business has been inside MTD since 1 April 2022. In practice that means the VAT return has to come out of digital records, not out of a shoebox and a calculator.

If you are below the £90,000 threshold and not registered, this does not apply yet — but it is the reason to think about what you invoice with before you cross it, rather than after.

What changes in 2029 — and what does not

On 28 October 2026 the government published its e-invoicing implementation roadmap. Here is what it actually says, because the headlines have been looser than the document.

From 1 April 2029, VAT-registered persons — including public sector bodies — will need to be able to issue and receive VAT invoices as e-invoices. Note both verbs. Receiving is as much a requirement as sending, and it is the half most people skip over.

The UK will adopt Peppol as its core interoperability framework. That is a structured exchange network, not a PDF emailed to a customer — a PDF is not an e-invoice under this definition.

Three things it is not

  • It is not real-time reporting to HMRC. The roadmap is explicit: no decision has been taken on whether e-invoicing digital reporting should be introduced. Do not let anyone sell you a system on that basis.
  • It is not settled yet. Requirements will be confirmed between October 2027 and April 2028. Anyone quoting you exact technical specifications today is guessing.
  • It is not a reason to register for VAT. The roadmap states the design will let smaller businesses use e-invoicing without having to register. Limited exemptions are expected, including for digitally excluded persons.

What a garage should actually do about it

Nothing urgent, and that is the honest answer. 2029 is two and a half years away and the detail is not written.

But there is one decision it should influence. If you are choosing what to run the workshop on now, prefer something where your invoices are structured data rather than a document you typed. A system that already holds the line items, the VAT rate and the VAT number as fields can be pointed at a network later. A Word template and a PDF cannot, and that migration will land on you in a year when you are busy.

That is the whole of the 2029 advice: do not buy for it, but do not paint yourself into a corner either.

One last number

You must register for VAT when your taxable turnover over the last 12 months goes over £90,000. It is a rolling 12 months, not a tax year, and you have 30 days from the end of the month in which you crossed it.

Garages cross it quietly, because parts turnover inflates the figure without inflating the profit. Watch the rolling total monthly, not annually.

Get the invoice right from the first job card.

Line-by-line parts and labour, VAT separate from the net, your VAT number on the document — and you can retitle it “VAT Invoice”. From £35/month, one user, up to 100 job cards a month.
