How to Write a Compliant Invoice in Malta (2026 Guide)

A clear, correct invoice is how you get paid and how you stay on the right side of Malta's VAT rules. Whether you are a freelancer sending your first invoice or a business issuing hundreds a month, this guide explains exactly what a compliant invoice in Malta must contain in 2026, when a simplified invoice or a fiscal receipt is enough, and the small mistakes that quietly cause late payments and VAT headaches.

Invoice, tax invoice or fiscal receipt?

Malta's invoicing rules come from the Value Added Tax Act (Cap. 406). The document you must issue depends on who your customer is:

• A tax invoice (full VAT invoice) is required when a VAT-registered person supplies goods or services to another VAT-registered person (B2B).
• A fiscal receipt is required when you supply a customer who is not VAT-registered, such as most consumers.
• Businesses registered as a small undertaking under Article 11 (turnover up to EUR 35,000 a year) do not charge VAT, but still issue an invoice or receipt for the work; it simply shows no VAT.

Not sure which VAT category you fall under? Our guide to Article 10 vs Article 11 registration breaks it down.

What a compliant Malta tax invoice must include

Under Cap. 406, a full tax invoice issued by an Article 10 business should show all of the following:

• The word "invoice" and a sequential invoice number from one or more series, with no gaps or reused numbers;
• The date of issue, and the date of supply (the tax point) where it differs;
• Your name, address and VAT identification number;
• The customer's name and address (and their VAT number for cross-border B2B sales);
• A clear description, quantity and unit price for each line;
• The VAT rate and the VAT amount charged, shown per rate where you mix rates;
• The taxable amount (net) and the total payable;
• Where you apply 0% or an exemption, a short note of the reason or legal reference.

Getting the VAT rate right on each line matters, because Malta uses 18%, 12%, 7%, 5% and 0%. Our Malta VAT and tax guide lists which rate applies to what.

The simplified invoice: the EUR 100 rule

For domestic supplies that do not exceed EUR 100 including VAT, you may issue a simplified invoice. It can leave out the customer's name, address and VAT number and the line-by-line VAT breakdown, as long as it still shows your details, the date, a description, and the VAT-inclusive amount with the rate applied. Simplified invoices cannot be used for cross-border sales, which always need a full invoice whatever the value.

Why sequential numbering is not optional

Invoice numbers must run in an unbroken sequence. Gaps, duplicates or numbers that jump around are exactly what a VAT inspection looks for, because they suggest missing sales. You can run more than one series (for example a prefix per year or per branch), but each series must be continuous. Deleting an invoice and reusing its number is a common, avoidable mistake; issue a credit note instead.

Five mistakes that make an invoice non-compliant

• No VAT number on a tax invoice, or quoting the wrong one.
• Missing the supply date when it differs from the issue date.
• One blended VAT figure instead of VAT shown per rate on mixed-rate invoices.
• Re-using or skipping numbers after cancelling a draft.
• No reason given for a 0% or exempt line.

A faster way to stay compliant

You can build invoices in a word processor or spreadsheet, but every field above then becomes something you have to remember by hand, every single time. That is the gap invoices.mt is built to close. It is invoicing made for Malta, so it assigns gap-free sequential numbers automatically, stores your VAT number and business details, captures both the issue and supply dates, lets you set the correct VAT rate per line and works out the VAT and totals for you.
