Hi,
If a person has acquired a property in the year 2007-08 and made improvements in the same year and later he constructed Ground floor and First floor in the year 2008-09 and constructed Second floor in 2010-11, whether indexed cost of acquisition in all the aspects? whether construction of GF, FF and SF attracts acquisition?? or not?? someone please enlighten me regarding this issue.
