Foreign currency and reverse charge
Where the invoice is in another currency, the VAT amount must be shown in AED with the exchange rate used. Where the customer accounts for the VAT under the reverse charge, the invoice must say so and refer to the relevant provision of the VAT law.
Progress invoices
A construction progress invoice is a full tax invoice. Its description should identify the certificate and period, and the amount should match the certified value plus VAT on the correct base.
