" I made a sale to other State charging VAT. is this legal or accountable, as the party not able to issue me a c form"

 

Your transaction is correct and accountable if you have charged the tax

as per the VAT rate in your state.

 

My Query is: then what about Purchaser... Whether he can avail this VAT paid on Purchase made from Other state without issue of C Form  to VAT Liabilty?
