Form 16 — What It Is & How to Use It
Updated June 2026 · VerifiedWhat Is Form 16 and Why Is It Important?
Form 16 is a TDS (Tax Deducted at Source) certificate that your employer issues after deducting tax from your salary under Section 392 of the Income-tax Act, 2025. It serves as proof that:
- Your employer deducted TDS from your salary during the Tax Year.
- The deducted TDS was deposited with the government.
- Your salary income, exemptions, and deductions have been computed correctly.
Form 16 is the primary document salaried individuals use for filing their Income Tax Return. It consolidates all salary-related information into a standardised format, making ITR filing straightforward.
What Does Part A of Form 16 Contain?
Part A is generated and downloaded by the employer from the TRACES portal. It contains:
- Employer details — name, address, TAN (Tax Deduction Account Number), and PAN.
- Employee details — name, PAN, and period of employment.
- Quarterly TDS summary — TDS deducted and deposited for each quarter (Q1 to Q4).
- Challan details — BSR code, challan serial number, date of deposit, and amount for each TDS payment.
- Acknowledgement numbers — quarterly TDS return filing acknowledgement (24Q).
What Does Part B of Form 16 Contain?
Part B is prepared by the employer and provides a detailed breakup of your salary and tax computation:
| Section in Part B | Details Included |
|---|---|
| Gross Salary | Basic salary, DA, HRA, special allowance, bonus, commission, leave encashment |
| Exemptions (Section 10) | HRA exemption, LTA, children education allowance, gratuity, etc. |
| Net Salary | Gross salary minus exemptions |
| Standard Deduction | ₹75,000 (new regime) or ₹50,000 (old regime) |
| Income from Other Sources | Interest or other income reported by employee to employer |
| Gross Total Income | Total of all income heads as reported to employer |
| Deductions (Chapter VI-A) | 80C, 80D, 80E, 80G, 80CCD, etc. (old regime only) |
| Taxable Income | Gross total income minus deductions |
| Tax Computed | Tax on taxable income as per applicable slab rates |
| Rebate under Section 87A | Rebate if income is within threshold |
| Health & Education Cess | 4% cess on tax + surcharge |
| TDS Deducted | Total TDS deducted during the year |
When Must the Employer Issue Form 16?
Under the Income-tax Act, 2025 (corresponding to the earlier Rule 31 of Income-tax Rules), employers must issue Form 16 by 15 June of the year following the Tax Year. For Tax Year 2026-27, the deadline is 15 June 2027.
- If you worked for multiple employers during the year, each employer must issue a separate Form 16 for the period you were employed with them.
- Form 16 must be issued even if no TDS was deducted (if salary was below the taxable threshold).
What If Your Employer Does Not Issue Form 16?
If your employer fails to provide Form 16:
- Request in writing — send a formal email or letter to your HR/payroll department citing Section 392 of the Income-tax Act, 2025.
- Use Form 26AS / AIS — download your Annual Tax Statement from the e-filing portal. It shows all TDS credited against your PAN, which can substitute for Part A data.
- Use salary slips — reconstruct Part B details from your monthly salary slips, showing gross salary, deductions, and net pay.
- Complain to the IT Department — if the employer refuses to issue Form 16, you can file a complaint with the jurisdictional TDS officer. Non-issuance attracts a penalty of ₹100 per day of default under Section 272A(2).
How to Use Form 16 for Filing Your ITR
- Verify Part A with Form 26AS — ensure TDS amounts match. Report discrepancies to your employer.
- Transfer Part B data to ITR — enter gross salary, exemptions, and deductions from Part B into the appropriate fields of your ITR form (ITR-1 or ITR-2).
- Add other income — Form 16 only covers salary. Separately add interest income, capital gains, rental income, and freelance earnings.
- Claim additional deductions — if you have deductions not reported to your employer (e.g., 80D health insurance paid personally), add them while filing.
- Submit and e-verify — complete the return and verify via Aadhaar OTP within 30 days.
Frequently Asked Questions
Is Form 16 mandatory for filing ITR?
No. Form 16 is not mandatory for filing your ITR. You can file using salary slips, Form 26AS, and AIS data. However, Form 16 simplifies the process significantly as it consolidates all salary-related tax information in one document.
What is the difference between Form 16 and Form 16A?
Form 16 is specifically for TDS on salary (Section 392). Form 16A is a TDS certificate for non-salary payments such as interest, rent, professional fees, and commission (Sections 393, 394, etc.). Banks issue Form 16A for TDS on fixed deposit interest, for example.
I changed jobs mid-year. Will I get two Form 16s?
Yes. Each employer issues a separate Form 16 for the period you worked with them. When filing your ITR, combine the salary details from both Form 16s. Be careful — each employer may have applied a separate basic exemption limit, potentially resulting in less TDS than your actual liability.
Can I download Form 16 from the Income Tax portal?
No. Form 16 is issued by your employer, not the Income Tax Department. However, you can download Form 26AS from the e-filing portal, which shows all TDS credited against your PAN and can serve as a cross-reference.
What if the TDS in Form 16 does not match Form 26AS?
Mismatches typically occur when the employer deposits TDS late or files incorrect TDS returns. Contact your employer’s payroll department to file a correction return. Always use Form 26AS as the source of truth since the IT Department credits refunds based on 26AS data, not Form 16.
