Dear u r not right... according to ur statement that zafar caterers deduct ur Rs. 52,000 tax as an Advance Income Tax + General Sales Tax & they provide u only Rs. 22,000 tax receipts. Dear if u have any idea about reverse calculation then do it and u'll find that zafar caterers are not cheaters.
if u going reverse calculation of 22,000 receipts is it is only ur advance tax then u find that 22,000*10=220,000
220,000*100/116=189,655
189,655*16/100= 30,344
it means that GST + Advance income tax = 22,000+30,344= 52,344
dear u you pay 52,000 as an tax but zafar caterers pay 52,344 on ur behalf , Rs.344 extra... so please don't create wrong information thanks i hope u get my point....
