What is Form 16?

Form 16 is a TDS (Tax Deducted at Source) certificate issued by your employer under Section 192 of the Income Tax Act. It certifies that tax has been deducted from your salary and deposited with the government.

💡 Think of Form 16 as your salary tax receipt. It's proof that your employer has deducted and deposited tax on your behalf.

If you're a salaried employee, Form 16 is the most important document for filing your Income Tax Return (ITR). Without it, you cannot accurately report your salary income and claim deductions.

Part A vs Part B: What's the Difference?

Form 16 is divided into two parts. Each serves a different purpose:

Feature Part A Part B
What it contains TDS deposit details, PAN, TAN Salary breakdown, allowances, deductions
Who generates it TRACES (auto-generated) Employer (manually prepared)
Can it be modified? No — fixed by TRACES Yes — employer prepares it
Authentication Digitally signed by TRACES Signed by employer
Key details TDS amount, deposit dates, challan numbers Basic salary, HRA, 80C deductions, taxable income

Part A — The Tax Proof

Part A is generated by the TRACES portal and contains:

Part B — The Salary Breakdown

Part B is prepared by your employer and includes:

⚠️ Important

If your salary exceeds ₹1,50,000, your employer must provide details of perquisites separately in Form 12BA. For lower salaries, perquisite details are included in Form 16 itself.
