What a UAE VAT return involves
A VAT 201 return reports output VAT on sales, input VAT on purchases and adjustments, split by emirate for standard-rated supplies and by treatment for zero-rated, exempt and reverse charge items. It must be filed, and any VAT paid, within 28 days of the end of the tax period.
Most of the effort is not the form itself. It is making sure every sale and purchase in the period is recorded with the right treatment, that input VAT is supported by valid tax invoices and that nothing is counted twice.
