Dear friends,

 

Amount paid to contractor on 1/10/2012.

tax deducted at source on the same day.

 so  due date for  deposit of tax is 7/11/2012

but deposited on  20/11/2012

so my doubt is whether interest is calculated for the period  of  7/11/2012 to 20/11/2012

                 or

1/10/2012 to 20/11/2012?

please Answere me friends.
