I have bought the flat no 304 in Satyam Platinum building Kamothe Navi Mumbai and yet to complete the full payment. I did registration in Feb 2012. I booked flat on 11 dec 2011 and architect's "virtual completion certificate" for building dated 23.11.2011 is avaialable. The Occupation Certificate is yet to come.Please let me know if I need to pay service and VAT for building which seems to complete prior to my booking in it. The builder is asking for 2.58% service tax & 1 % VAT. Please let me know if I need to pay Service tax & VAT. I will be thankful to esteem lawyers.
