Hello @tax007
As per the IT Act, bank needs to deduct TDS on interest paid / accrues to the customer and deposit it to the Government. Thus, there will be no interest on TDS amount since it is deducted and paid to the government against your PAN. In case your total income is below taxable income, you can claim the refund of the same while filing ITR. You do not have to wait till maturity of FD for claiming of refund of TDS amount deducted by the bank.
For Senior/ Non senior citizen, the limit stands at non taxable income. In case your total income across all sources is below basic exemption limit then you can file respective forms, submit it to bank and there will be no TDS on interest income.
Thank you.
