Hi, I hav changed my company during last November, henceforth I have Form16 from last April'06 to Nov'07.. and from my new company it is from Nov'07 to Mrach'08... in earlier Form16 Taxpayable is mentioned as 0. and in the current it is approx Rs 10K, but while filing return thru an online website, it is showing my tax payable for this year is approx 20k, why is this so??.. I hav shown investment upto 1,00,000 ... but still why do i need to pay so much tax... can anybody please explain...
