ANSWER:

If you were caught by the authorities, they would consider this to be tax evasion and this is against the law. You must demand the purchase taxes bill.

I have a shop in India. When we buy goods for reselling most of our wholesalers don’t give us a tax bill is which is by law a must. When we don’t get the purchase tax bill we cannot show a sales tax when we sell a product. The some products on which we get a purchase tax bill, we are ready to pay the sales tax to the government after the sales . In this case is my earning halal.
