s your vat registration in UAE rejected? This is a question that many people ask and are not aware of the consequences that can follow if they do not comply with these rules. The UAE has very strict rules and regulations when it comes to VAT registration. If you are a business owner, then it is your responsibility to ensure that all necessary documents are submitted on time and without any errors. If there is an error in any document, then your VAT(Value Added Tax) registration could be rejected.
