There's a small correction in the response from one of our fraternity members.
Understanding Form 16
Form 16 is purely a financial document based on the total emolument being paid by the company, along with the details of the applicable Income Tax that is deducted from your salary (which the Finance team submits to the Income Tax Department).
This document helps you with the details of your earnings (and tax deposited) from your employer. Similarly, the various banks from where you would have earned interest on your Fixed Deposits, HDFC Ltd., Company F.D.'s, etc., will all furnish you with Form 16 specifying the total money you would have received from the respective source along with the deducted tax (which each of these banks/HDFC Ltd. would have deposited with the income tax against your PAN number).
Filing Your Returns
Your CA or you need to consider all these details from various Form 16s while filing your returns, computing your total earnings for the year, and calculating the applicable tax, already paid-out tax, and the due tax. You can also get the same details to reconfirm the total earnings from 26AS, which is a document that you can pull out for yourself by furnishing your PAN details on the income tax website. The same is also available by opening your account through internet banking and clicking on the link 26AS, which will lead you to the income tax website. So, all these Forms help you calculate your income tax accurately, which needs to be paid out to the Income Tax Department while filing your returns.
That's it about Form 16.
