Digital signature is a computer proof that a document was written by an authorized entity and hasn’t been changed since it was sent out. For the UAE’s phased e-invoicing deployment, which is set to happen in 2026 and 2027, digital signatures are needed.
During this stage, companies will not only make e-invoices, but they will also send them to FTA’s systems in real time. With the cryptographic protection of digital signature for e-invoicing in UAE, you can be sure that the information on a statement is correct and hasn’t been altered in any way.
Additionally, digital signatures help authorities be sure that a business has concocted a legitimate invoice. A public-key infrastructure (PKI) can be used to check this. The invoice is signed with a safe private key that was given to the business. After that, FTA will cross-verify this signature using a public key that is linked to it.
Is it Mandatory to Have a Digital Signature on the Invoice?
Yes, digital signature for e-invoicing in UAE are a prerequisite for the new e-invoice system. As part of the new system, which will be required for all B2B and B2G deals starting in stages in July 2026, every e-invoice needs to be digitally signed to make sure it is verified, factual, and can’t be contested.
What Digital Signatures Do and How They Work?
The digital signature is like a wet-ink signature but works electronically. It creates a safe, unchangeable audit trail that is very important for VAT checks and settling disputes.
Trust and Authentication: The signature proves that the sender is who they say they are and that the data on the statement has not been changed since it was sent.
FTA Follow-up: The Federal Tax Authority (FTA) and the Telecommunications and Digital Government Regulatory Authority (TDRA) have rules about what licenses and technology can be used to make digital signatures.
Automated Process: A lot of the work is done automatically. Companies need to work with an FTA-approved Service Provider (ASP). The ASP’s systems will add the cryptographic signature to every invoice before sending it over the secure Peppol network.
Major Technical Rules to Consider for Digital Signature einvoicing UAE
The UAE’s e-invoicing system is built on a decentralized Continuous Transaction Control (DCTCE) 5-corner model that uses Peppol standards. It has strict technical rules about digital signatures, such as
- Service Providers (ASPs) with an accreditation: For businesses to validate, e-sign, and share e-invoices, they need to choose an ASP that has been approved by the Ministry of Finance.
- Formats with Structure: Invoices must be structured and in a file that computers can read, like XML or JSON, and they must follow PINT-AE or UBL standards. Once the rule is put into place, PDFs, Word documents, or scanned copies will not be accepted as legal e-invoices.
- Steps taken for safety: ASPs must use secure transmission methods and have certifications like ISO/IEC 27001 in addition to digital signatures to protect and keep data private.
Actionable Steps For Businesses
To make sure they follow the rules, businesses should:
- Connect systems: Make sure that their ERP or accounting systems can connect to a trusted ASP so that they can create bills in the right XML or JSON format and allow digital signatures to be generated automatically.
- Pick a Service Provider: Choose an FTA-approved solution provider early so that there is plenty of time for system testing and training before the due dates.
- Train Staff: Learn the new steps, validation alerts, and compliance steps with the business and IT teams.
- Fines and penalties from the FTA may be given to people who don’t follow these rules.
