A Dubai agency, VAT-registered and making only taxable supplies, engages a UK firm for AED 100,000 of consulting. The UK invoice shows no UAE VAT. Here is exactly what goes on the return.
The calculation
Step 1, the supply value: AED 100,000, entered in the return's box for supplies subject to the reverse charge provisions.
Step 2, output VAT: 5% of AED 100,000 = AED 5,000, included in the return's output tax. This is the VAT the agency declares as the buyer.
Step 3, input VAT: AED 5,000 claimed as recoverable input tax on the same return, because the agency makes only taxable supplies.
Net effect: AED 5,000 output minus AED 5,000 input = nil. No VAT cash leaves the agency, but both entries are on the return and the FTA can see the full trail. Now flip one fact: if the agency also made exempt supplies, it could only recover part of that AED 5,000, and the unrecovered portion becomes a real cost.
The golden rule this example shows: reverse charge is a reporting exercise, not a payment, right up until your recovery position is less than 100%. Reconciled monthly books make sure these supplies are never missed in the first place.
