We were having a partnership firm dealing as an agency for only one company and were alloted the PAN number and were filing Returns regularly. Since May 2006, this agency is terminated by our principals and we are not doing any business and there is no income or expenses. We have filed a NIL return for the FY 2006-07. Are we to file the Nil return every year or can we surrender the PAN card and how to do the same.
