12 July 2011 In our case TDS was deducted as on 26-03-2011 and the same paid on 07-05-2011 i.e after the due date of 30-04-2011
Further interest was calculated @ 1.5% for two months
my question is
1.whether should i calculate the interest for two months
2.whether should i calculate the interest for three months in the following way
26-03-2011 TO 31-03-2011 - One Month
01-04-2011 T0 30-04-2011 - Second Month
01-05-2011 To 07-05-2011 - Third Month

In which way i should calculate the interest for late deposit of TDS Deducted

Anybody please clarify the same as soon as possible
