any has sent me FBT dues for FY2008-2009

Hello everybody,

My earlier company, which I resigned in March 2009, has sent me FBT for the financial year 2008-2009 in dec2009.

My company gave me stock options in NYSE, which I sold in March 2009. The trading company withheld 33% of the money (for FBT). Thus I filed my returns in july 2009 with 0 tax liabilty.

I left the company in match 2009.

Now my company has sent me FBT calculation sheet for 2008-2009, which says that I have to pay more FBT, which I have to pay to the company.

Please help me on this

(1) Is it legal and correct to send me the tax calculations now, after the date for tax returns for 2008-2009 has also gone?

(2) If I have to pay this money, can I show this money as capital loss? Can it be adjusted againt income?

(3) Can it be adjusted only against capital gains from shares etc?

(4) Can I show this as loss after the due date for taxes have gone? I have read that I cannot claim any returns/losses after the due date for taxes.

Thanks in advance

I really need help on this
