Form 16 Explained 2026: Meaning, Part A & B, and How to File ITR Using It

Every year, around May or June, salaried employees across India receive a document from their employer called Form 16. For many people, it is the first thing their chartered accountant asks for when it's time to file the income tax return. Yet a surprising number of employees have no idea what it actually contains or why it matters.

This guide is a plain-language breakdown of everything you need to know about Form 16 in 2026 — what it is, what Part A and Part B mean, who gets it, how to download it, and how to actually use it to file your ITR. We have also covered the most common mistakes people make, along with answers to questions that come up every year.

1. What is Form 16?

Form 16 is a TDS certificate that your employer issues after deducting tax at source from your salary.

Form 16 is a TDS (Tax Deducted at Source) certificate that every employer in India is required to issue to their salaried employees. It is governed by Section 203 of the Income Tax Act, 1961.

In simple terms, when your employer pays you a salary, they first deduct a certain amount as income tax on your behalf and deposit it with the government. Form 16 is proof that this deduction happened. It shows exactly how much your employer paid you, how much tax was deducted, and how much was deposited with the Income Tax Department.

Think of it as a report card of your salary and taxes for a complete financial year. For FY 2025-26 (which runs from April 1, 2025 to March 31, 2026), your employer must issue Form 16 by June 15, 2026.

2. Why Form 16 is Important

Form 16 is the single most important document for salaried employees when filing an income tax return.

If you are a salaried employee, Form 16 is probably the most important tax document you will deal with all year. Here is why it matters so much:

• Proof of income: Banks, housing finance companies, and visa authorities often ask for Form 16 as income proof. It is considered more reliable than a salary slip because it covers the entire year.
• Proof of TDS payment: It confirms that the tax already deducted from your salary has actually been deposited with the government. This protects you from any future disputes.
• Makes ITR filing easier: All the figures you need to fill in your Income Tax Return — gross salary, allowances, deductions, and TDS — are already there in Form 16. You just have to cross-verify and transfer them.
• Claim refunds accurately: If excess tax was deducted from your salary (which happens when your investments were declared late), Form 16 helps you correctly claim that refund.
• Loan applications: Home loans, car loans, and personal loans often require Form 16 for the last one or two years as part of the documentation.

3. Part A vs Part B — What's the Difference?

Form 16 has two distinct parts — Part A is generated by the government, while Part B is prepared by the employer.

Form 16 is divided into two parts. Many people confuse them or think they are the same. They are not.

Part A — The Government's Record

Part A of Form 16 is generated by TRACES (TDS Reconciliation Analysis and Correction Enabling System), which is a portal run by the Income Tax Department. Your employer downloads this part from TRACES after depositing the TDS.

Part A contains:

• Your employer's name, address, and TAN (Tax Deduction Account Number)
• Your name, address, and PAN (Permanent Account Number)
• The assessment year for which TDS was deducted
• A quarter-by-quarter breakdown of TDS deducted and deposited
• The BSR code and challan details for TDS deposits

Part B — The Employer's Calculation

Part B is prepared by your employer (not the government). It contains the detailed salary breakdown for the entire financial year.

Part B contains:

• Gross salary, including basic pay, HRA, special allowances, and other components
• Exemptions claimed — such as HRA exemption, LTA, and other allowances
• Deductions allowed under Chapter VI-A (Section 80C, 80D, 80CCD, etc.)
• The total taxable income after all exemptions and deductions
• Tax computed on that taxable income under the applicable regime
• Education cess and total tax payable
• TDS already deducted and any balance tax

4. Who Gets Form 16?

Any salaried employee where TDS has been deducted is entitled to receive Form 16 from their employer.

Not every salaried employee automatically gets Form 16. Here is the rule:

Form 16 is mandatory when TDS has been deducted. If your annual salary is below the basic exemption limit and no TDS was deducted, your employer is not legally required to issue Form 16. However, many employers issue it anyway as a good practice.

For FY 2025-26 (AY 2026-27), the basic exemption limits are:

• Under Old Regime: ₹2.5 lakh (₹3 lakh for senior citizens aged 60-80; ₹5 lakh for super senior citizens above 80)
• Under New Regime: ₹4 lakh (effectively ₹12.75 lakh after Section 87A rebate and standard deduction for salaried individuals)

5. How to Download Form 16

Form 16 is typically issued by your employer, though Part A data can be verified via the income tax e-filing portal.

You cannot download Form 16 yourself from the income tax portal. It is the employer's job to generate and share it. However, here is how the process works for both sides:

For Employees

Your employer will provide Form 16 either as a PDF sent by email or through your company's HRMS (Human Resource Management System). You just need to download it from there. Most large companies also allow employees to access it through employee self-service portals.

The deadline for employers to issue Form 16 for FY 2025-26 is June 15, 2026.

For Employers (How They Generate It)

1. 1
   Log in to TRACES

   The employer logs into the TRACES portal at tdscpc.gov.in using their TAN credentials.

2. 2
   File TDS returns (Form 24Q)

   The employer must have filed quarterly TDS returns (Form 24Q) for all four quarters of the financial year before generating Form 16.

3. 3
   Download Part A from TRACES

   After TDS returns are processed, the employer requests and downloads Part A for each employee from TRACES.

4. 4
   Prepare Part B

   The employer prepares Part B in-house, listing the salary details, exemptions, and deductions for each employee.

5. 5
   Issue the combined Form 16

   Both parts are combined (usually as a single PDF) and shared with employees before June 15.

6. How to Use Form 16 for ITR Filing

Filing your ITR using Form 16 is straightforward once you know where each piece of information goes.

For most salaried employees, ITR-1 (Sahaj) is the form to use, provided your income is only from salary, one house property, and other sources like interest — and total income does not exceed ₹50 lakh. Here is how to use your Form 16 to file it correctly:

1. 1
   Log in to the Income Tax e-Filing portal

   Go to incometax.gov.in and log in with your PAN and password. If you have not registered, do it first — it takes about 10 minutes.

2. 2
   Check your pre-filled return

   The portal now pre-populates many fields using data from your employer's TDS returns and Form 26AS. Start by reviewing this pre-filled data — most of your salary, TDS, and deductions should already be there.

3. 3
   Enter / verify gross salary from Part B

   From Form 16 Part B, take the gross salary figure and cross-check it with what is pre-filled. Look at the breakup — basic, HRA, special allowances, and any other component.

4. 4
   Add exemptions (Old Regime only)

   If you are under the Old Tax Regime, enter the exemptions from Part B — HRA exemption, LTA, uniform allowance (if applicable), and any other exempt allowances your employer has calculated.

5. 5
   Enter Chapter VI-A deductions (Old Regime only)

   From Part B, find the deductions your employer has already considered — 80C, 80D, 80CCD(1B), home loan interest under 24(b), etc. Enter these in the appropriate fields. If you have additional investments beyond what the employer counted, add those too.

6. 6
   Verify TDS credited using Part A

   From Part A of Form 16, note the total TDS deducted and verify it matches the TDS credit showing in your Form 26AS. If there is a mismatch, do not proceed — contact your employer first.

7. 7
   Add income from other sources

   If you have interest income from savings accounts, fixed deposits, or any other income, add those separately. Form 16 only covers salary income. Use your Form 26AS and AIS for a complete picture.

8. 8
   Verify tax computation and submit

   Once all details are in, the portal will compute the final tax payable or refund. If there is a balance tax, pay it using Challan 280 before submitting. Then e-verify using Aadhaar OTP, net banking, or a bank account. You can also use Numvexa's Income Tax Calculator to verify the computation independently.
