Here I need not worry about paying my taxes as the payer of my income will at the time of paying me my income, deduct a part of it and deposit it with Government as tax on my behalf.
Payer means:
My employer in case of salaries
The bank in case of interest on deposits
The tenant in case of rentals (over some limit)
The payer of business receipts whether professional or contractual (again this is sometimes, if the other person is a business entity)
I should only worry if I don’t have enough incomes and find that its an unnecessary tax payment out of my income. Such as if I am drawing only salary or pension income, and after saving, there would be no tax on my income, I should tell my employer/payer about my planned savings, so that he considers that while determining my deduction of tax at source.
For other payers, if my income going to be is below taxable, say I am a senior citizen drawing only interest income, which is likely to be below my exemption limit, I can fill up a form every year and give to bank asking banker not to deduct my tax at source.
