What Is Form 16? A Complete Guide for Salaried Employees in India

Form 16 is a TDS certificate issued by your employer under Section 203 of the Income Tax Act. It certifies that your employer has deducted tax on your salary and deposited it with the government. For most salaried individuals in India, Form 16 is the starting point for filing their annual Income Tax Return (ITR). Employers are legally required to issue Form 16 by 15 June each year for the preceding financial year.

Form 16 vs Form 16A vs Form 16B

These three forms are often confused:

This guide focuses on Form 16 — the salary TDS certificate.

Part A vs Part B: What Each Contains

Form 16 has two mandatory parts:

Part A is generated directly from the TRACES (TDS Reconciliation Analysis and Correction Enabling System) portal and contains:

• Employer's TAN and PAN
• Employee's PAN
• Period of employment during the FY
• Quarter-wise TDS deposited to the government

You can verify Part A on the TRACES portal by entering your PAN, employer TAN, and year.

Part B is prepared by the employer and contains:

• Gross salary breakup (basic, HRA, allowances, perquisites)
• All deductions claimed (80C, 80D, HRA exemption, professional tax, standard deduction)
• Taxable income after deductions
• Tax computed at applicable slab rates
• Rebate under Section 87A (if applicable)
• Net tax payable vs TDS deducted

How to Read Form 16 for ITR Filing

Step 1: Collect Form 16 from employer (by 15 June)
Step 2: Log in to incometax.gov.in → e-File → File ITR
Step 3: Select ITR-1 (for salary + one house property + other income ≤ ₹50 lakh)
Step 4: Most fields auto-populate from Form 26AS and AIS
Step 5: Cross-verify with Part B: gross salary, deductions, taxable income
Step 6: Enter any additional income not covered by employer (FD interest, capital gains)
Step 7: Verify total tax payable vs TDS already deducted
Step 8: Pay any balance tax as Self-Assessment Tax (Challan 280)
Step 9: e-Verify using Aadhaar OTP, net banking, or DSC

What to Do If You Changed Jobs During the Year

If you worked for two employers in the same FY, you will receive Form 16 from each. However, each employer calculates TDS based only on the salary they paid, without knowing your income from the other employer. This commonly leads to under-deduction of TDS.

The correct approach: inform your second employer about your income from the first employer so they can compute TDS accurately. Submit the pay slips or Form 12B to the new employer. If TDS has been under-deducted, calculate the balance tax and pay it as Advance Tax before 15 March to avoid interest under Section 234B/234C.

What If My Employer Does Not Give Form 16?

Employers are legally obligated to issue Form 16 if they have deducted TDS. If they refuse, you can:

1. File a complaint with your jurisdictional TDS officer
2. Still file your ITR using salary slips and your Form 26AS — the TDS credit will appear there regardless

If no TDS was deducted (income below threshold), the employer is not required to issue Form 16, but you can request Form 12BA for perquisite details.

Form 16 and the New Tax Regime

From FY 2023-24, Form 16 Part B must indicate whether the employee opted for the old or new tax regime. If you want to switch regimes, inform your employer via a revised declaration — do not simply assume the ITR filing will handle it, as the employer will have already deducted TDS under one regime.
