I have booked a flat few months back in Noida. Now my builder Logix Infrastructure Pvt Ltd is charging Service Tax on payments made after 1st July 2010 at the rate of 2.75 on Basic Sale Price and 10.33 on payments made towards other charges, particularly including the Lease Rent (which we buyer have to pay to Noida Authority). Is the builder right in collecting Service Tax on Lease Rent.
