We wish to buy a flat in Mumbai after selling our flat in Pune. The flat in Pune is in my mother's name, we want to avoid capital gains, so is it advisable for my mother and father to have a joint ownership? Also, if this happens will it impact the exmeption claimed by my mother on the property?
Since the Pune Flat is owned by your mother, capital gains will arise to your mother. By investing in another residential flat exemption u/s. 54 of the Income Tax Act can be claimed upto a value of subsequent purchase.
Further the Mumbai flat can be purchased in joint ownership of your mother and father. Joint ownership will not have any impact on exemption that will be available to your mother under section 54 of the Income Tax Act.
