Form 16A is a certificate issued by a deductor (such as an employer, bank, or financial institution) to the deductee (the taxpayer) as proof of tax deducted at source (TDS) on payments made to the taxpayer. It is primarily used for payments other than salaries, such as payments for professional fees, rent, or interest. After filing the TDS return (Form 26Q) for payment other than salary, you need to download Form 16A.
