How to calculate Municipality fee, Service charge, and VAT for restaurants in Dubai

Question

Restaurants in Dubai charge Municipality fee, Service charge, and VAT.
Let's say all Prices are inclusive/exclusive of 10% service charge, 7% Municipality fee and 5% VAT.
How can I calculate this? Also, how are each fee calculated?

Answer 1

First receipt has these charges listed out explicitly, on other receipts the prices are already inclusive (although the VAT amount is explicitly shown).

So for example, the last receipt shows AED1531.00 charge which is inclusive of all the taxes. It then lists the taxes: 5% VAT, 7% Mun. fee, 10% service. Total 22%. So 1531.00 is 122% of the original amount. Your total before taxes thus is 1254.92 (1531 / 1.22). You can then calculate each of the taxes from that amount. It may not add up perfectly because of the rounding errors.
