What is Form 16?
Form 16 is a certificate issued by employers to employees under Section 203 of the Income Tax Act. It acts as official proof that tax has been deducted from your salary at source (TDS) and deposited with the government. Under the new Income-tax Act, 2025, Form 16 transitions into Form 130, carrying forward similar structure details but aligning with modern simplified e-filing systems.
✓ Mandatory Issuance Date
Employers must issue your Form 16 / Form 130 on or before June 15 of every assessment year. If you have changed jobs within the financial year, you should collect Form 16 from all previous employers.
Structure of Form 16: Part A vs. Part B
Form 16 is divided into two distinct components, both of which are critical for filling out your return:
1. Part A: The TDS Credit Certificate
Part A is generated and downloaded by the employer from the government's TRACES portal. It contains verified quarterly tax deposit details:
Employer's Name, Address, and TAN.
Employee's Name, Address, and PAN.
Summary of tax deposited quarterly and authenticated with a unique TRACES certificate number.
2. Part B: The Salary and Deduction Breakdown
Part B is prepared by the employer's payroll team. It acts as an annexure to Part A, showing exactly how your tax liability was calculated:
Gross Salary breakdown (Basic salary, allowances, and perquisites).
Exemptions claimed (such as HRA, LTA, or other standard allowances).
Standard Deduction (₹75,000 under the New Tax Regime for FY 2025-26).
Deductions under Schedule XV or Chapter VI-A (Section 80C / Section 123 details like PF, PPF, NPS, medical insurance).
Net Tax Payable or Refund due.
How to Use Form 16 to File Your ITR-1 Online
Filing your return using Form 16 is straightforward because the tables in Form 16 align directly with the schedules on the e-filing portal:
Log in to the e-filing portal and choose File Income Tax Return.
Select ITR-1 (if your total income is below ₹50 Lakhs and you do not have business income or capital gains).
Under the Income from Salary section, match the fields with Part B of your Form 16 (Gross Salary, Exempt Allowances, and Net Salary).
In the Deductions schedule, input the values for Section 123 (PPF, ELSS) or Section 80D as listed in Part B.
Go to the TDS Schedule and cross-verify that the TDS amounts match Part A of your Form 16. Ensure the employer's TAN is entered correctly.
Proceed to payment or submit, and e-verify within 30 days.
⚠ Check for Errors Early
Compare the TDS amount in Part A with your Form 26AS (Form 168). If the amount shown in Form 26AS is lower, the tax portal will auto-populate the lower value, leading to a tax demand notice. If there is a mismatch, request your employer to file a correction return.
Can You File ITR Without Form 16?
Yes. If your employer has not issued Form 16 (for example, if your income was below the taxable limit and no TDS was deducted), you can still file your return. Collect your monthly salary slips to calculate your gross salary, download your AIS / Form 26AS to verify that zero TDS was deducted, and compute your tax liability using our online calculators.
