For the Company issuing the gift voucher (presuming no consideration was collected for the same) to the customers, exception can be claimed if the total output VAT payable on all deemed supplies given by the Company for a 12 month period is less than AED 2,000 (taxable value AED 40,000). Here the term person refers to the Company itself and not the recipient of the supply. Also, the term person denotes each Company in a Tax Group and not the Group as a whole since they have not used the wording "Taxable person", in my view. So exception based on this clause may not be available. However it is perhaps possible to cite the reason that no input tax was claimed on the acquisition of these vouchers since the purchase did not constitute a taxable supply, hence onwards free give away should not qualify as a deemed supply (just my view). Furthermore it is mentioned that these vouchers were purchased from same Tax Group Company. So it should be noted that, presuming the customers need to redeem these vouchers for purchases from that VAT group company, taxable point arises at the time of redemption for the VAT Group.

Thanks Sajith, How tax will be applied on voucher sales (FOC) if company claimed input VAT already?

The value of deemed supply is the cost of acquiring the goods/service which is given FOC
