it is like this,
for accounting purpose the total interest wht you have paid/payable will be treated as expenditure and will b booked.
but for income tax, the treatment is different for Self occupied HP and Let out HP.
if the property is a self occcupied property where the capital borrowed after 1-4-99, the max permissible interest is Rs.150000/-
for letout property there is no such restriction, the actual interest paid/payable will b allowed.
plz consider following illustration:
mr.X has borrowed funds from "S" bank for his HP, the agrred interest rate at the time of saction is 8%, but the bank started charging the interest @ 8.25% after some time due to change in the bank interest rate. The barrower has approached banking ombudsmen for settlement. The ombudsmen has decided the case and awarded the verdict in favor of the barrower
now in this situation, the assessee is eligible to claim @ 8.25%, though he may not actually pay the interest, but if the settlement is done for 8%, then he should treat that excess claim as income in the year in which tht settlement done, and liable to tax.
