dont worry, banks are required to file their annual accounts within 1 month from end of FY. & accounts of banks are audited within 10 days or so.
so now if your TDS is correctly duducted & Paid then it reflecte in 26AS. if they dont duduct/paid correctly then they have to transfer the amount to your account.
morever you can ask 16A from bank if TDS credit is not display in 26AS.
as per CBDT circular, few judgments & 205 sec of incometax.
“205. Bar against direct demand on assessee. — Where tax is deductible at the source under (the foregoing provisions of this Chapter), the assessee shall not be called upon to pay the tax himself to the extent to which tax has been deducted from that income.”
so u can cliam amount on base on 16A.
hope your query is solved.
dont forget to thanks
