your tax statement always says how much tax you gave even if it was paid by employer on YOUR BEHALF before you got the money in your account or if the company has paid tax on YOUR BEHALF if you have earned on shares.
Dont mix it with the tax COMPANIES pay (corporate tax) in which NS is shareholder that is totally different from personal tax.
After the “self assessment” system is introduced, you are bound to tell how much tax you have already paid. Just think for a min, can some sane mind accept the returns submitted by these politicians (across board) as true returns?
