Advance tax for fd interest

Hello all,

I have some income from my FD (Fixed Deposits) as their interest i am earning.  I have not asked my employer to deduct taxes on this amount.  

I wanted to know what is process to deposit the taxes for this amount if i want to do this on my own.  Previous year i calculated this amount only at the time of ITR filing and paid SAT (self assessment tax) but i have to pay some interest on that amount under section 234B and 234C (my CA did this).

I want to avoid paying any interest this time and pay taxes as anyway i will do that.

Can someone guide me on this.

Regards,

Vivek
