When you must register for UAE VAT — and when you shouldn't wait
Mandatory registration is triggered once taxable supplies and taxable imports in the previous 12 months exceed AED 375,000, or once you reasonably expect to exceed that threshold in the next 30 days. The 12-month test is rolling, not calendar-year — it looks back on any 12 consecutive months.
Voluntary registration is available from AED 187,500 of taxable supplies (or taxable expenses). For most B2B businesses invoicing UAE-registered clients, voluntary registration below the mandatory threshold is worthwhile: your clients recover the VAT you charge, and you recover input VAT on your own costs.
Non-resident businesses making any taxable supplies in the UAE — including e-commerce sellers, SaaS platforms and digital-service providers — must register from the first taxable transaction. There is no threshold. This catches out international sellers who assume UAE VAT works like US sales tax.
