	Hi Bruno.  the sale should be within one year from the date the trasnfer took place.
	Yes to claim the exemption, you will be required to file your I-T return on or befoer the due date of furnishing your I-T Return.  In that the detailed of calculation of the Capital  Gains should be given as below:
	Sale Consideration                                           xxxxxx
	Less: Brokerage Paid    xxxx
	             Indexed Cost of Acquisition xxxxxx    xxxxxx
	                       Long Term Capital Gains         xxxxxx
	Less; Exemption u/s 54                                    xxxxxx
	LTCG chargeable to tax                                    xxxxx
	If the Cost of Acquisition of the new house is less then the Capital Gains then on the balacne you wud be requried to pay LTCG tax  @ 20%.
	Your Indexed COA would be the Cost of the Acquisition of the house purchased multiplied by Cost Inflation Index for the year when the sale took place divided by Cost Inflation Index of the Year when the property was being purchased.
