Service tax on purchase of property

If you have paid some advance earlier, then service tax has to be paid. Service tax is not payable where the entire consideration is paid by the buyer after issuance of completion-certificate by the competent authority. 

Agreed with Mr. Mayur.

Okay....thank you Mr. Mayur and Ravi.

so i will have to conffirm that wether the completion certificate has been isued or not,right?

Yes, you need to verify whether such certificate has been issued prior or later to payment of consideration.
