When Should I Submit an E-Invoice in UAE? VAT 14-Day Rule Explained

If you are wondering, when should I submit an e-invoice, it is not dependent on a specific date on the calendar. It is dependent on VAT legislation, namely the date of supply.

According to UAE VAT rules, a tax invoice must be issued within 14 days from the date of supply.

This means that it is dependent on when the goods were delivered or when the service was provided, and not on your accounting system.

There is no legislation that states “submit all invoices by the 30th” or “submit at the end of the month.” The legislation is dependent on when the transaction occurred.

Ideal Submission Time

The best time to send an e-invoice is as soon as the taxable supply takes place and not later than the 14-day limit specified in VAT legislation.

For instance:

Sending the invoice after 14 days may raise compliance issues, particularly if it impacts VAT returns. VAT returns should be submitted for the right tax period, depending on the date of supply. Sending the invoice late may raise the chances of making errors in VAT returns.

But once the UAE's structured e-invoicing system is fully implemented, the answer will be even more clear. The system will be able to track when the invoice was issued and sent out. This will ensure that the date the UAE tax authorities receive the e invoice is directly traceable to the compliance process.

FAQs

If you are wondering when should I send an e invoice, the answer is that it depends on the date of supply. Under UAE VAT law, a tax invoice must be issued within 14 days from the date of delivery of the goods or completion of the services. It is not tied to month-end or accounting cycles.

2. Is there a specific date for e invoice submission that UAE businesses must follow?
