How can I know the quantum of tax deducted from my income by the payer?

Ans.  To know the quantum of the tax deducted by the payer, you can ask the payer to furnish you a TDS certificate in respect of tax deducted by him. You can also check Form 26AS from your e-filing account at https://www.incometax.gov.in/iec/foportal

You can also use the “View Your Tax Credit” facility available at www.incometaxindia.gov.in
