At present, taxpayers taking housing loans are eligible for income-tax exemption on interest payment of up to Rs 1.5 lakh every year. Besides this, the repayment of principal amount is part of investments eligible for benefit under Section 80(C) of the Income-Tax Act, which has a ceiling of Rs 1 lakh.

The government has already identified housing as one of its focus areas, a fact highlighted by President Pratibha Patil in her address to both the houses of Parliament.

The existing tax exemption limit is considered inadequate at a time when a two-bedroom house in big cities costs at least Rs 25 lakh.

Considering a person takes a loan of Rs 20 lakh at an interest rate of 9.5 per cent, he would pay Rs 1,88,493 towards interest alone in the first year. His annual interest payment in the first five years would be more than Rs 1.5 lakh.
