1. What Is Form 16?
Form 16 is a TDS (Tax Deducted at Source) certificate issued by your employer under Section 203 of the Income Tax Act, 1961. It is the official document that tells you — and the Income Tax Department — exactly how much salary you earned and how much income tax was deducted from your salary during the financial year.
Think of it as your employer's formal statement: "Here's what we paid you, and here's the tax we deducted and deposited on your behalf."
| What Form 16 contains | Why it matters for ITR |
|---|---|
| Your total salary and all components | This becomes your income from salary in the ITR |
| Exemptions claimed (HRA, LTA etc.) | Directly used in your ITR deductions section |
| Deductions allowed (80C, 80D etc.) | Pre-computed by your employer for the ITR |
| Tax computed and TDS deducted | Cross-checked with Form 26AS before filing |
| Employer PAN, TAN, and your PAN | Verified by IT Department to link TDS to you |
When should you receive Form 16? Your employer must issue Form 16 by 15 June 2026 for FY 2025-26. Employers who deducted TDS and fail to issue Form 16 are liable for a penalty of ₹100/day under Section 272A(2)(g).
2. Form 16 Part A vs Part B — What's the Difference?
| Feature | Part A | Part B |
|---|---|---|
| Source | Downloaded from TRACES (government portal) | Prepared by employer |
| Contains | Employer TAN & PAN, your PAN, quarter-wise TDS deposited, total TDS, challan details | Gross salary breakup, exemptions (HRA, LTA), Chapter VI-A deductions, net taxable salary, tax computed |
| Authentication | TRACES watermark + certificate number (verifiable) | Employer sign/stamp on company letterhead |
| Purpose | Proof of TDS deposit with government | Input for ITR income and deductions |
Important: A valid Form 16 must have both Parts A and B. Some employers issue only Part B on letterhead without the TRACES-generated Part A — this is incomplete. Always check that your Part A has the TRACES watermark and a certificate number.
3. How to Read Form 16 Part A
Part A is standardised and generated by the IT Department's TRACES portal. Here are the key fields and what they mean:
| Field | What It Means |
|---|---|
| Name & Address of Employer | Verify this matches your appointment letter or payslips. |
| TAN of Employer | Tax Deduction Account Number. Must match Form 26AS. |
| PAN of Deductee (You) | Your PAN. If wrong, the TDS credit will not appear in your account — raise it with HR immediately. |
| Assessment Year | For FY 2025-26 this should read 2026-27. Verify this — employers sometimes issue the previous year's Form 16. |
| Period of Employment | Your tenure with this employer. Important for job-changers — should reflect only your service period, not the full year. |
| Amount of Tax Deducted | Total TDS deducted from your salary. Must match Form 26AS exactly. A difference means TDS was deducted but not deposited — a serious issue. |
| Quarter-wise Details | TDS by quarter (Q1: Apr–Jun, Q2: Jul–Sep, Q3: Oct–Dec, Q4: Jan–Mar). |
| Certificate Number | TRACES-generated. Verify at tdscpc.gov.in → Verify TDS Certificate. |
4. How to Read Form 16 Part B
Part B is the salary computation annexure prepared by your employer. This section feeds directly into your ITR:
| Field | What It Means |
|---|---|
| Gross Salary (a) | Total CTC components — basic, HRA, special allowance, medical, LTA, other allowances, and perquisites. |
| Exemptions u/s 10 (b) | Tax-exempt allowances: HRA u/s 10(13A), LTA u/s 10(5), children education allowance. Computed by your employer based on declarations and rent receipts. |
| Balance = (a) – (b) | Gross salary minus exemptions — enters into tax computation. |
| Standard Deduction | ₹75,000 under new regime / ₹50,000 under old regime. Automatic — no proof required. |
| Deductions u/s VI-A | Deductions declared to your employer: 80C (PPF, ELSS, LIC, home loan principal), 80D (health insurance), 80CCD(1B) (NPS), etc. |
| Net Taxable Income | The amount on which tax is computed. Must match your ITR computation. |
| Relief u/s 89(1) | Relief for salary arrears received in the current year relating to a previous year. |
5. How to Use Form 16 for ITR Filing
Form 16 is your single most important input document. Here is how each field maps to your ITR:
| Information From Form 16 | Where It Goes in Your ITR |
|---|---|
| Gross Salary (Part B) | Schedule Salary → Gross Salary |
| HRA / LTA exemptions u/s 10 | Schedule Salary → Allowances exempt u/s 10 |
| Standard Deduction (₹75K / ₹50K) | Schedule Salary → Standard Deduction |
| 80C deductions (Part B) | Schedule VI-A → Section 80C |
| 80D deductions (Part B) | Schedule VI-A → Section 80D |
| TDS deducted (Part A) | Schedule TDS1 → TDS on Salary |
| Employer TAN (Part A) | Schedule TDS1 → TAN of Employer |
| Net Taxable Salary (Part B) | Cross-verify with ITR computation |
Before you use Form 16: Download your AIS (Annual Information Statement) from incometax.gov.in and cross-check the TDS figure in Form 16 Part A against what appears in your AIS. If they don't match, raise it with your employer before filing.

6. What to Do If You Have Two Form 16s (Changed Jobs)
If you changed jobs during FY 2025-26, you will receive one Form 16 from each employer. This requires careful handling.
The key risk with two Form 16s: Each employer calculates TDS as if they were your only employer for the year. Neither knows about the other's salary. The combined income may push you into a higher tax slab, resulting in short TDS deduction — and you owe the balance when you file.
Step-by-Step: Filing ITR with Two Form 16s
- Collect both Form 16s — Part A + Part B from each employer. Verify the employment periods together cover April 2025 – March 2026.
- Add the salary incomes — Add gross salary figures from both Part B sections. Do NOT simply add net taxable salaries, as deductions may overlap.
- Check deduction overlap — Both employers may have allowed full 80C (₹1.5L) separately. In aggregate, you can only claim ₹1.5L total. Correct this while filing.
- Add TDS from both employers — Total TDS = TDS from Employer 1 + TDS from Employer 2. Enter both in Schedule TDS1 with their respective TANs.
- Compute aggregate taxable income — Calculate tax on the combined income. If total tax exceeds total TDS, pay the difference via Challan 280 before filing.
- Use ITR-2 if needed — Multiple Form 16s usually means ITR-2 unless both tenures together result in a simple salaried profile eligible for ITR-1.

7. What to Do If You Don't Have Form 16
Situation A — Employer didn't deduct TDS (income below taxable limit)
If your salary is below ₹4 lakh (new regime), your employer may not have deducted any TDS. You can still file ITR using monthly salary slips, bank statements, and your AIS / Form 26AS.
Situation B — Employer deducted TDS but hasn't issued Form 16
- Request formally in writing (email to HR / payroll) — keep the email for records
- Download Form 26AS / AIS from incometax.gov.in — it shows all TDS credited to your PAN, even without Form 16
- Use salary slips as the income basis
- If the employer refuses, file a grievance at incometax.gov.in or contact your Assessing Officer
Filing without Form 16 is possible using salary slips + Form 26AS + bank statements. A CA can reconstruct the filing accurately even without the physical Form 16.
8. How to Verify Form 16 Is Genuine
- Check the TRACES watermark — Part A should have a digital watermark stating it was downloaded from TRACES
- Verify the certificate number — Go to tdscpc.gov.in → Verify TDS Certificate. Enter the certificate number, TAN, and PAN. The portal will confirm if genuine.
- Cross-check with Form 26AS — The TDS amount in Part A must exactly match what appears in your Form 26AS under the same TAN and financial year
- Check quarterly consistency — Quarter-wise TDS amounts in Part A must add up to the total TDS figure
- Part B should have employer sign/stamp — on company letterhead with an authorized signatory
Frequently Asked Questions
What is Form 16 in income tax?
Form 16 is a TDS certificate issued by your employer under Section 203 of the Income Tax Act, 1961. It certifies how much salary you were paid and how much income tax was deducted and deposited on your behalf during the financial year. It is the primary document for ITR filing by salaried employees.
What is the difference between Form 16 Part A and Part B?
Part A is generated directly from the TRACES government portal. It contains the TDS certificate number, employer TAN, your PAN, and quarter-wise TDS deposit details. Part B is an annexure prepared by your employer showing your detailed salary breakup, exemptions, deductions, net taxable salary, and tax computed. Both parts together form your complete Form 16.
Is it mandatory for employers to issue Form 16?
Yes — if your employer has deducted TDS, it is legally mandatory to issue Form 16 by 15 June 2026 for FY 2025-26. Failure to issue Form 16 attracts a penalty of ₹100 per day under Section 272A(2)(g).
Can I file ITR without Form 16?
Yes — Form 16 is not mandatory for filing ITR. You can use salary slips, bank statements, and your AIS / Form 26AS to reconstruct the required figures. However, Form 16 makes the process far more accurate since it has pre-computed figures already verified by your employer.
What should I do if I have two Form 16s from different employers?
Collect both Form 16s and combine the salary income from both. Key risks: each employer may have allowed full 80C (₹1.5L) separately, but you can only claim ₹1.5L in total. Also, the combined income may push you to a higher slab than either employer accounted for. Pay any shortfall via Challan 280 before filing. A CA is strongly recommended for this scenario.
By when should I receive Form 16 for FY 2025-26?
Your employer must issue Form 16 for FY 2025-26 by 15 June 2026. If you haven't received it by then, email HR formally requesting it. You can also use your AIS and salary slips to file your ITR without waiting.
How do I verify that my Form 16 is genuine?
Go to tdscpc.gov.in → Verify TDS Certificate. Enter the certificate number (from Part A), employer TAN, and your PAN. The portal confirms authenticity. Also cross-check the TDS amount in Part A against what appears in your Form 26AS.
