It is over and above the existing deduction of Rs 2 lakh available on interest payment of a home loan under section 24b. Therefore, this deduction will only be useful if the total interest payment on your housing loan was above Rs 2 lakh in financial year 2019-20. Therefore, you need to get hold of your home loan repayment statement and check the total interest paid during the year. If it is above Rs 2 lakh and you fulfill all the essential conditions, make sure that you get additional deduction.
