What do you mean by Form 16?

Form 16 is a TDS certificate and it is issued by an employer to their employee when tax has been deducted from salary under Section 192 of the Income Tax Act.

The certificate is divided into two parts: Part A includes details of the employer and employee and also contains information related to the tax deducted and deposited with the government, whereas Part B contains detailed information of salary income, including allowances, exemptions, deductions claimed, and tax calculations.

What details should you check in Form 16?

You should check details like mismatch in salary details, missed deductions, incorrect PAN, or uncredited TDS which can result in refund delays or even tax notices.

Check your personal and employment details

Start by verifying simple details like your name, PAN, employer’s name, TAN, financial year, and assessment year, as even small mistake in this information can lead to issues with TDS credit or ITR filing.

Match the Form 16 salary with your payslips for accuracy

Compare Form 16 salary details with your monthly payslips and annual salary statement to make sure that they are matching. Your gross salary, allowances, bonuses, and other components should align with your employment records, and any mismatch should be clarified with your employer before filing your return.

Carefully cross-check any other income and deductions

Ensure that you have covered all your investment made towards tax savings in areas like 80C, 80D, and 80CCD and also ensure that any other source of income like interest from home loans and savings accounts has been accounted for.

Check which tax regime has been used for TDS calculation

Ensure that Form 16 reflects the correct taxation scheme under which your employer has deducted TDS. You can switch taxation schemes during the filing of ITRs.

Cross check Form 16 with your AIS and Form 26AS

Compare your information in Form 16 with the AIS and Form 26AS before filing your return to check whether there are any mistakes in respect of all income or Tax Deduction at Source entries in the forms. This will assist you to find out if salary income, tax credits, interest payments, dividends, and others are shown correctly. In addition, make sure the tax credit information in Form 16 appears in Form 26AS.

Report errors immediately

If you find any errors in Form 16 such as incorrect salary details, deductions or TDS information then immediately contact your employer’s HR, payroll or finance team as they can file a revision of the TDS return and send an updated Form 16.
