Definition
The form follows the structure the FTA uses on its filing page: VAT on sales and other outputs, then VAT on expenses and other inputs, then the net VAT due. Article 64(5) of the Executive Regulation sets the minimum contents of any return, including your TRN, the tax period, the value of standard-rated and zero-rated supplies and their tax, exempt supplies, expenses with recoverable input tax, and the totals of tax due and recoverable.
Standard-rated sales are reported emirate by emirate, so a business with shops in Dubai and Ras Al Khaimah splits its sales between the two.
