UAE e-invoicing turns your invoices into structured records that a machine reads. Most of what it needs is data you already ask clients for — but only if you asked before the invoice was issued. AudiTax tells you what is missing now, while collecting it is still a conversation rather than a cleanup.
AudiTax is not an Accredited Service Provider. It does not transmit invoices to the exchange network and reports nothing to the Federal Tax Authority on your behalf — that requires an accredited provider, and appointing one is a separate step you will take when the regime reaches you. What AudiTax does is make sure the data you hand that provider is complete.
The pilot runs from 2026 and firms under AED 50 million turnover follow in 2027. Nothing in AudiTax blocks an invoice over a missing e-invoicing field today, because refusing to issue one would be inventing a rule that does not exist yet. The gaps show as a note beside the record, not an error in front of it.
One check does block, and it always has: an invoice cannot be issued without your own Tax Registration Number, because UAE VAT law requires that today.
Fixed once, in Settings. Six checks.
Your Tax Registration Number
Every e-invoice identifies the seller by TRN. It is also required on a UAE tax invoice today.
Your business address
A structured invoice carries the seller address as separate fields, not free text on a page.
Your emirate
The address has to resolve to a recognised subdivision before it can be encoded.
Your country as a two-letter code
Structured formats want ISO codes — “AE”, not “UAE” or “United Arab Emirates”.
A business email address
The network needs somewhere to send acknowledgements and rejections.
A network participant identifier
Issued by the exchange network once you register through a service provider. Nothing to do until then — it is listed so the eventual step is visible rather than surprising.
Fixed on the client record, and worth doing at onboarding. Five checks.
The client's Tax Registration Number
A standard tax invoice between VAT-registered businesses names the buyer by TRN.
The client's address
Carried as structured fields on an e-invoice.
The client's country as a two-letter code
Structured formats want ISO codes — “AE”, not “UAE”.
The client's email address
The exchange network routes to an address; it is also how the invoice is delivered today.
A document fingerprint
Issued invoices are fingerprinted so they can be proved unchanged. This one should never be missing — if it is, the invoice was not properly issued.
For an invoice that has already been issued, AudiTax reads the party details frozen onto the document, not today's client record. That is the honest answer: the document that would be transmitted is the one that was issued, and correcting a client's address now does not change what was already handed over. Drafts read the live client instead, because a draft has frozen nothing yet.
These are eleven fields. A full structured invoice specification carries considerably more, and AudiTax does not check your tax treatment, your rates, or whether a position is correct. This is a data-completeness report, not a validation service and not tax advice.
Phase dates and requirements change. Check these rather than any vendor's summary of them, including ours.
