 Dear frnds                                 

              we are all knowing about that expenses allowable even if it is not paid during the year but paid before due date (30th sep or 31st Jul)  as per sec 43B of Income Tax Act,1961

                                              Such section includes tax,cess,duty,fee but it excludes service tax ...!!!!!!

any reason for that ....?????
