Tax for March 2020 and 31st March 2020

Due date for March 2020 remains at April 30, 2020. There is no extension of due date for payment. However, where TDS is paid after the due date, instead of existing penal interest rate of 1% p.m (12% p.a), a lower rate of 0.75%(9% p.a) will have to be paid.

However, TDS returns can be filed till June 30, 2020 without any late fees

But as per section it says 

0.75% per month or part of the month for delay in remittance beyond due date only in the case of due dates falling between 20 March 2020 and 29 June 2020. If the sum remains unpaid after 30 June, the normal interest of 1.5% is chargeable

Period of delay means  period between due date and date on which tax is paid

So for March 2020 TDS , 1.5% interest and 0.75% interest for April, may and June - if we are going to pay on or before 29 June 2020
