VAT Registration and Deregistration in the UAE: A Complete Guide

VAT registration in the UAE is required once a business's taxable supplies cross a defined threshold, and understanding both when registration becomes mandatory and how deregistration works later (if a business closes or falls below the threshold) matters for staying compliant with the Federal Tax Authority (FTA) throughout a company's lifecycle.

Registration becomes mandatory once a business's taxable turnover exceeds AED 375,000 over a rolling 12-month period, while voluntary registration is available once turnover exceeds AED 187,500, useful for newer businesses that want to reclaim input VAT on expenses even before they're legally required to register. Registration is completed through the FTA's EmaraTax portal, and once approved, the business receives a Tax Registration Number (TRN), which needs to be referenced on invoices and is increasingly treated by banks and business partners as a basic marker of legitimacy, beyond just its tax function.

Deregistration works in the reverse direction: it's required if a business's taxable turnover falls below the AED 187,500 threshold, if the business ceases making taxable supplies entirely, or if it closes down or undergoes a structural change like a merger. Continuing to hold VAT registration after falling below the threshold is now treated as a compliance issue in its own right, not simply an optional continuation, so businesses whose revenue has genuinely declined need to actively apply for deregistration rather than assuming inactivity resolves the matter on its own.

A detail worth understanding clearly: VAT deregistration and corporate tax deregistration are separate processes but need to be coordinated together, since VAT cessation typically triggers corporate tax filing obligations for the final tax period, and any mismatch between the two filings (different cessation dates, inconsistent financial reporting) can trigger cross-tax reconciliation checks and delay the deregistration process. Given how the FTA has moved toward increasingly digital, data-driven reconciliation between VAT and corporate tax records, businesses going through deregistration for any reason are generally well served by ensuring both processes are handled together and consistently rather than treating them as entirely separate administrative tasks.
