We are a company  operating in Karnataka.We are paying service tax to our canteen contractor.(after 50% abatement)Now, he is claiming Karnataka VAT of 5% (Under composition scheme as selected by canteen contractor) on the entire value of the bill.

My question is  on 50% we have paid service tax.On the remaining 50% we will pay VAT @ 5%.

Is it correct ?
