The govt in Budget 2020-21 brought an optional income tax regime, under which individuals and Hindu Undivided Families (HUFs) were to be taxed at lower rates if they did not avail specified exemptions and deductions, like house rent allowance (HRA), interest on the home loan, investments made under Section 80C, 80D and 80CCD. Under this, total income up to Rs 2.5 lakh will be tax-exempt.
