Sir/Madam, please tell me the quarterly TDS return filing liability in case where Deductor deduct tax at source in the month of march for the whole year. For ex. Mr.A (Deductor) has paid interset to Mr. B(Deductee) on monthly basis as per T & C which is above threshold limit i.e. above 5000/- without deducting Tax at source. Now in the month of march he has deducted total Tax and deposited with interest penalty i.e. 1% per month. now my question is whether Mr. A is liable to file all quarterly return or he can file the return only for fourth quarter.
