Tax calculation if employed in more than 1 company in a FY

Hi,

I was working for a company from Apr 2010 to Dec 2010 and joined another company(current) from Jan 2011. I have both Form-16s.

in 1st company(Apr-Dec 2010):                    in current company(Jan-Mar2011):

gross salary - Rs. 5,75,365.00                     gross salary - Rs. 3,11,617.96

TDS - Rs. 26,536                                              TDS - Rs. 2,590

I think due to the 2 times chapter VIA deduction and 2 times tax slab exemption, the TDS are less and i need to calculate chapter VIA and tax slab as 1 time, is this correct ?. till now i have not paid any self-assessment tax. please someone let me know under what section in 234B , 234C i will have to calculate.

Thanks,

B.Sathish Kumar
