Your query is incomplete on the following points.
1) State- Which state VAT 2) Are you purchasing the job work materials from URD or Registered parties 3) Items purchased 4) what is the process name or jobwork undertaken.
Any how, Vat is payable on sale of materials or on works contract. VAT on purchase is liable only in the case of purchase made from a un-registered dealer in your state. That too, after paying the tax it can be set off.
