A business must register for VAT if their taxable supplies and imports exceed the mandatory registration threshold of AED 375,000.
Furthermore, a business may choose to register for VAT voluntarily if their supplies and imports are less than the mandatory registration threshold, but exceed the voluntary registration threshold of AED 187,500.
Similarly, a business may register voluntarily if their expenses exceed the voluntary registration threshold. This latter opportunity to register voluntarily is designed to enable start-up businesses with no turnover to register for VAT.
