As some of your registration information may have become outdated (e.g. trade license, business activities), you will have to complete your "first amendment" application in EmaraTax by following the below steps:
1) Login to EmaraTax and navigate to your Taxable Person tile
2) Click on the "Actions" button on your VAT or Excise Tax tile to amend your registration application.
Once your first amendment application is approved by the FTA, an "Edit" option will be enabled in your “Actions”. Click on "Edit" and follow the steps where you will find the option to link your customs registration number with your TRN.
