 PCIT vs. IVen Interactive Limited (Supreme Court)

1. 143(2):

Mere mentioning of new address in the return of income is not enough. If change of address is not specifically intimated to the AO, he is justified in sending the notice at the address mentioned in PAN database. If the notice is sent within the period prescribed in s. 143(2), actual service of the notice upon the assessee is immaterial.

 It is required to be noted that notices under Section 143(2) of the 1961 Act are issued on selection of case generated under automated system of the Department which picks up the address of the assessee from the database of the PAN. Therefore, the change of address in the database of PAN is must, in case of change in the name of the company and/or any change in the registered office or the corporate office and the same has to be intimated to the Registrar of Companies in the prescribed format 12 (Form 18) and after completing with the said requirement, the assessee is required to approach the Department with the copy of the said document and the assessee is also required to make an application for change of address in the departmental database of PAN, which in the present case the assessee has failed to do.
