VAT Invoices for Garages: UAE, UK, US and Saudi Arabia

A garage invoice mixes parts and labour, business and private customers, and sometimes several tax rates on one document. The rules for what that invoice must show depend on the country, and in some countries on whether it is issued electronically. This guide summarises what a garage should know in the United Arab Emirates, the United Kingdom, the United States and Saudi Arabia. It is general information, not tax or legal advice: rules change, so confirm the details with your tax authority or an accountant before you rely on them.

What every garage invoice needs

Whatever the country, a clear garage invoice answers the same questions:

• Who is selling: your business name, address and tax registration number, if you are registered.
• Who is buying: the customer’s name, and for business customers their address and tax number.
• Which document it is: a unique, sequential invoice number and the date of issue.
• What was supplied: each part and each labour operation on its own line, with quantity, unit price and any discount.
• How much tax: the rate on each line, the tax amount and the total with and without tax.

If your job cards already record the vehicle, the lines and the customer’s tax number, most of this is filled in before the invoice is printed. The country-specific details are what follow.

United Arab Emirates: Tax Invoice and TRN

VAT in the UAE is charged at a standard rate of 5%, and some supplies are zero-rated. A VAT-registered garage must issue a tax invoice for taxable supplies, and the Federal Tax Authority (FTA) expects it to show, among other things:

• The words “Tax Invoice” displayed clearly on the document.
• Your name, address and Tax Registration Number (TRN).
• The customer’s name and address, and their TRN if they are registered.
• A sequential invoice number, the date of issue and the date of supply if it is different.
• A description of each part and service, the quantity, unit price, tax rate and tax amount.
• The tax payable expressed in AED, even if you invoice in another currency.

The rules also allow a simplified tax invoice in some situations, for example for customers who are not VAT registered. Check the current conditions on the FTA’s website before you use one. A UAE TRN has 15 digits; it is worth checking the customer’s number on the job card rather than copying it from memory. For UAE businesses, Baktam prints sales receipts and completed job cards with the title Tax Invoice in English and Arabic, your TRN, the customer’s TRN where recorded, and VAT broken down by rate.

United Kingdom: VAT invoice

UK VAT has a standard rate of 20%, a reduced rate of 5% and a zero rate. Most garage work, parts and labour, is standard-rated. If you are VAT registered, you must give a VAT invoice to VAT-registered customers; private customers do not have to receive one, but many garages give the same document to everyone. A full VAT invoice shows:

• A unique invoice number that follows on from the previous one.
• Your business name, address and VAT registration number.
• The invoice date and the time of supply (tax point) if different.
• The customer’s name or trading name and address.
• For each line: a description, quantity, price excluding VAT and the VAT rate.
• The total excluding VAT, any discount, and the total VAT charged.

HMRC allows a simplified VAT invoice for smaller retail sales; the limit is currently £250 including VAT. Keep in mind that invoices are only half of the picture: under Making Tax Digital, VAT records must be kept digitally and returns filed through compatible software, which is a separate task from printing invoices.

United States: sales tax invoices

The US has no VAT. Instead, most states, and many counties and cities, charge sales tax, and rates and rules differ from place to place. A few states have no statewide sales tax at all. For garages the biggest difference is labour: some states tax repair labour, others exempt it when it is shown separately from parts, and the treatment of fees such as shop supplies or tyre disposal also varies. Some states also have consumer rules for auto repair, for example requiring a written estimate before work starts.

In practice this means a US shop invoice should list parts and labour on separate lines, apply the correct combined rate to each taxable line, show the sales tax as its own amount and keep a record of any exemption, such as a resale certificate from a trade customer. Your state’s department of revenue publishes the rules for motor vehicle repair; they are the authority, not general guides like this one.

Saudi Arabia: ZATCA e-invoicing

Saudi Arabia charges VAT at 15%. What sets it apart is e-invoicing: the Zakat, Tax and Customs Authority (ZATCA) requires VAT-registered businesses to issue their invoices electronically through a compliant solution, a programme known as Fatoora. It has two phases. The first, the generation phase, started in December 2021 and requires invoices to be generated and stored electronically in a structured format. The second, the integration phase, connects the invoicing solution to ZATCA’s platform and is being rolled out in waves, with businesses notified by ZATCA when their turn comes.

Under Fatoora, standard tax invoices are used mainly for business customers and simplified tax invoices for consumers, and simplified invoices must carry a QR code. A garage in Saudi Arabia therefore cannot simply print a nicely formatted PDF and call it a tax invoice.

In the integration phase, the business onboards its own e-invoicing unit: it generates a one-time password on the Fatoora portal, and the software uses it to obtain the unit’s certificate (CSID) and pass ZATCA’s compliance checks. From then on, every invoice is signed and sent to ZATCA. Simplified invoices are reported within 24 hours of issue, while standard invoices must be cleared by ZATCA before they go to the customer.

Be clear about what your software does. Baktam supports Phase 2: once your unit is onboarded, each sale is signed as XML, reported or cleared, and printed as a Simplified Tax Invoice or Tax Invoice with ZATCA’s QR code. A sale that has not reached ZATCA yet prints as Invoice with a note that it is not a ZATCA e-invoice. Note that Baktam does not issue ZATCA e-invoices today on its own: someone has to issue each sale, so make it part of the daily routine to stay inside the 24-hour window. Credit notes for cancelled sales are not created automatically yet either.

UAE e-invoicing from 2027

The UAE has announced its own e-invoicing programme, built on the Peppol network. Instead of sending a PDF, invoices will be exchanged in a structured format through accredited service providers and reported to the FTA. It is scheduled to become mandatory in phases from 2027, starting with larger businesses. Until your phase starts, printed or PDF tax invoices remain the norm. Baktam is not yet connected to the Peppol network, so garages that fall into an early phase will need an accredited provider.

A checklist before you issue invoices

1. Enter your legal business name, address and tax number exactly as registered.
2. Check that your default tax rate and any zero or reduced rates match the rules for your country.
3. Record business customers’ tax numbers on their customer card, not on each invoice by hand.
4. Keep parts and labour on separate lines, especially where labour is taxed differently.
5. Make sure invoice numbers are sequential and never reused, even for cancelled documents.
6. Know whether e-invoicing applies to you (Saudi Arabia today, the UAE from 2027) and which solution you will use.
7. Keep copies for as long as your tax authority requires.
