    Yes, in case you have not deposited TDS by the due date, the following penalties might be applicable:

    • Interest (if you do not deposit the TDS amount in time)

    • Late filing fee (if you do not file by the deadline)

    • Penalty (if TDS is not filed within one year of the due date)

    Hope this helps!
