interest on tds u/s 201

18 % PY nw u calcalate 

I agree with u Samir sir ,
but i want to know if u have deducted tds on last day of month nd deposited it one day after the due date.

nw will int be payable for 2 months?

7 of every month last date for tds so if u paid on

8 interest is payable @ 1.5% per month

 here u have to pay for one month i think

since interest is charged 1.5%per month or part of month.
Suppose, i have deducted TDS on 30th June, and deposited it on 08th of july then 1 day of June will be treated as one month and 8 days of July will be another one month.
Hence total period is 2 months. Since,
As per the Act , interest is charged from the period when tds is deducted to till tds deposited .
