Filing exemption for very senior citizens when bank deducts tax on pension and interest, relieving return obligation. A relief permits very senior resident individuals whose entire income comprises pension and interest from a bank account, and who furnish the prescribed declaration, to have tax deducted by the bank after allowing Chapter VI-A deductions and rebate; if tax is deducted under this bank deduction provision, the senior citizen is not required to file an income-tax return for that previous year.
