cumbersome situation, as there are too much provision of penalty and concealment under the law for so much delay in filing the return.
1) straightway 5000/- penalty for late filing of return, if the date of filing return is taken in notice by the AO
2) if selected for scurtiny then ITO will insist that the property was brought in the year of declaration, and wiould like to add the value under taxable income, however the assesee may file appeal and get rellef from the appelete authority.
3) in General practice, a property is not sold overnight , so there may be some agreement on 31/03/2014 i belive, and some kind of token advance may had been paid also, i belive, on that ground you can save yourself that as agreemtn was there the property is booked for yourself only, however final procurement and payment was done in later year/s, keep your records fulfilled as per the return filed,
4) Sec 154 is an alternative to rectify yoiur mistakes, but it can be done only if you are assessed u/s 143(1), and demand raised or no demand case, but if the file is pulled for regular / scurtiny u/s 143(3) then you have to appear and face the situation.
