vat registration has been made compulsory for the ones whose taxable products and services pass a threshold of AED 375,000 of a year. This is not a small order as if anyone is seen not following them, he will get punished and will have to pay penalty as well. S, people must mind all of their taxable supplies so that they do not get any penalty on anything they do or not do.
You must show the VAT claimed as a separate total in your purchase records. This is quite important or else there may arise more complications for you.
