Tds on service tax ???

Mr Rupesh, Can you please mention the case law regarding the same.

But what in case if Service is subject to Reverse Charge. In case if a business entity take the services of an advocate and are billed for Rs. 50000/- excluding Service Tax. Then would they deduct TDS on Rs. 50000/- or Gross up the amount and deduct on Rs. 56180/-?

In case of tax deduction u/s 194J...the grossed up amount will be subject to such deduction. Hence, in your case, Rs 56180 shall be subject to TDS.
