UAE Free Zone vs Mainland: What Changes on Your Invoices (2026)

Choosing between a UAE free zone and the mainland is usually framed as a licensing question. But the choice follows you onto every invoice you issue: it determines your VAT treatment on some transactions, your corporate tax profile, and what your customers expect to see on the document. Here is how the two regimes differ in practice — and what to put on the invoice in each case.

First, the things that do not change

VAT applies across the UAE at 5% regardless of where you are licensed. A free zone company above the AED 375,000 mandatory registration threshold must register with the Federal Tax Authority (FTA) exactly like a mainland company, obtain a Tax Registration Number (TRN), and issue compliant tax invoices. The same invoice fields are required everywhere: the words tax invoice, supplier name and TRN, sequential number, date, customer details, line descriptions, VAT rate and amount, and totals in dirhams. A simplified tax invoice is permitted for supplies below AED 10,000 to unregistered customers.

Designated zones: where VAT gets interesting

A subset of free zones — fenced areas listed by Cabinet decision, such as Jebel Ali Free Zone and Khalifa Industrial Zone — are designated zones with special VAT rules for goods:

• Transfers of goods between designated zones can be outside the scope of VAT if conditions are met.
• Goods supplied within a designated zone for incorporation into other goods may be out of scope.
• Services, however, are almost always treated as supplied inside the UAE and taxed normally at 5%.

This is the single most misunderstood area of UAE VAT. A software company in a designated zone still charges 5% on services to mainland clients; a trading company moving goods between two designated zones may not charge VAT at all. Document the movement carefully and verify borderline cases with the FTA — getting it wrong in either direction creates exposure.

Corporate tax: the 0% question

Since June 2023, UAE corporate tax applies at 9% on taxable income above AED 375,000. Free zone entities can access a 0% rate on qualifying income as a Qualifying Free Zone Person (QFZP), if they maintain adequate substance in the zone, earn qualifying income (broadly, transactions with other free zone persons and certain listed activities), stay within the de minimis limit for non-qualifying revenue (the lower of AED 5 million or 5% of total revenue), comply with transfer pricing rules, and file audited financial statements.

Sell too much into the mainland and you can lose QFZP status for the whole period — the 0% is a privilege with a cliff edge. Mainland companies simply pay 0% up to AED 375,000 of profit and 9% above it. The details are covered in our UAE corporate tax guide.

Invoicing differences at a glance

Practical invoicing rules to live by

• Bill from the licensed entity. The name, license number, and address on the invoice must match your trade license — mismatches delay payment and can invalidate input VAT for your customer.
• Show your TRN prominently once registered; mainland corporate clients will refuse tax invoices without it.
• Track mainland revenue separately if you are a QFZP — your de minimis calculation depends on it, and clean invoicing categories make the year-end test painless.
• State the place of supply for goods moving through designated zones, with supporting delivery documents. Our delivery note guide covers the paperwork.

Which setup wins?

If your customers are mainly UAE mainland businesses and consumers, mainland licensing keeps life simple: one tax profile, no QFZP tests. If your business is genuinely international — exporting services, trading goods through ports, serving other free zone entities — the free zone route can preserve a 0% corporate tax rate that mainland companies cannot access. Either way, the invoice is where your choice becomes visible to the FTA. Set your template up correctly once, and every document that follows inherits the compliance.
