UAE e-invoicing runs on structured invoices carrying fields most client records were never asked for. AudiTax checks eleven of them across your firm and your client book, and tells you which client each gap sits on. The deadlines below are the ones that decide when this stops being optional for you.
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.
Which deadline applies to you depends on revenue, not on firm type. The voluntary pilot opened on 1 July 2026. Businesses with revenue of AED 50 million or more must appoint an Accredited Service Provider by 30 October 2026 and issue electronically from 1 January 2027; everyone else appoints by 31 March 2027 and starts on 1 July 2027. Failing to appoint on time carries a penalty of AED 5,000 for each month the appointment is late.
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. Nothing else in AudiTax blocks an invoice over a missing e-invoicing field, 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.

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.
It depends on revenue, not on what kind of firm you are. Businesses with revenue of AED 50 million or more must appoint an Accredited Service Provider by 30 October 2026 and issue electronically from 1 January 2027. Everyone else appoints by 31 March 2027 and starts on 1 July 2027. Government entities appoint by 31 March 2027 and start on 1 October 2027.
A penalty of AED 5,000 applies for each month the appointment is late. Appointing is also not instant: the provider has to be accredited, and the data you hand them has to be complete, which is the part you can start on today.
No. AudiTax is not an Accredited Service Provider. It does not transmit on the exchange network and reports nothing to the Federal Tax Authority. Your appointed provider does that; AudiTax makes sure the data you give them is complete.
Eleven. Six are about your firm: your TRN, your business address, your emirate, your country as a two-letter ISO code, a business email address, and a network participant identifier once you have one. Five are about each client and invoice: the client TRN, the client address, the client country as an ISO code, the client email address, and a document fingerprint.
Because you cannot backfill it later on invoices already issued. AudiTax reads the party details frozen onto an issued document, not today’s client record, so correcting a client’s address now does not improve an invoice you handed over last quarter. Drafts read the live client, because a draft has frozen nothing yet.
Only one will, and it always has: your own Tax Registration Number, because UAE VAT law requires it on a tax invoice today. Every other gap shows as a note beside the record. Blocking an invoice over an e-invoicing field would be inventing a rule that does not exist yet.
No. This is a data-completeness report. It does not check your rates, your treatment, or whether a position is right. That judgement stays with your firm.
No. Only a structured invoice transmitted through an Accredited Service Provider counts once the mandate reaches you. A PDF or a paper invoice does not, however correct its contents are. That is why the data has to be complete and machine-readable rather than merely printed.
No, and the two are independent. You can run the readiness check and fix the gaps now, before you have chosen a provider. When you do appoint one, the data you hand over is already complete, which is the expensive part to fix afterwards.
Phase dates and requirements change. Check these rather than any vendor's summary of them, including ours.
