What Form 16 is, what Part A and Part B contain, how it links to your TDS and Form 26AS, and how to use it when filing your return.

Key points

  • Form 16 is a TDS certificate your employer gives you for tax deducted from your salary.
  • Part A shows employer/employee details and a quarterly summary of TDS deposited.
  • Part B shows the salary breakup, deductions and the tax computed.
  • The TDS in Form 16 should match your Form 26AS and AIS — reconcile them before filing.
  • Form 16 is issued only if tax was deducted from your salary; keep it with your filing records.

If you are salaried and tax was deducted from your pay, your employer gives you a Form 16. It is one of the most useful documents at filing time because it summarises your salary and the tax already paid on your behalf. Here is how to read it.

What Form 16 is

Form 16 is a TDS certificate for salary. “TDS” is tax deducted at source — the tax your employer withholds from your salary each month and deposits with the government. Form 16 is the employer’s certificate that this happened, and how much. It is generated through the TRACES system, so the figures tie back to what the employer reported to the tax department.

Part A: the summary

Part A is the identity-and-totals section. It typically shows:

  • Your name and PAN, and the employer’s name and TAN.
  • The assessment year and the period of employment.
  • A quarter-by-quarter summary of the tax deducted and deposited.

Part A is the part that must match the TDS shown in your Form 26AS, because both come from what the employer reported.

Part B: the computation

Part B is the detailed working. It usually shows:

  • Your gross salary and its components.
  • Exemptions and the standard deduction.
  • Any deductions considered (for example under Chapter VI-A, if you are in the old regime).
  • The taxable income and the tax computed on it.

Part B is essentially a ready-made salary computation you can carry into your return. If you had more than one employer in the year, you should get a Form 16 from each.

How to use it when filing

  1. Check that the PAN, name and assessment year are correct.
  2. Match the TDS in Part A against your Form 26AS and AIS.
  3. Carry the salary and tax figures from Part B into your return (the e-filing portal often pre-fills much of this).
  4. Add any income not in Form 16 — for example bank interest — before you file.

Reconcile before you file

The single most common filing mistake is not matching Form 16 against Form 26AS and AIS. See our Form 26AS, AIS and TIS guide and TDS explained.

If something is missing or wrong

Form 16 is issued only when tax was deducted from salary. If you expected one and did not get it, ask your employer. If the figures look wrong, raise it with the employer so they can correct their TDS return — filing on mismatched numbers can trigger a notice. Keep your Form 16 with your filing records.

Frequently asked questions

What if my employer did not give me Form 16?
Employers are required to issue Form 16 where tax has been deducted from salary. If no tax was deducted, there may be no Form 16. Either way, you can still file your return using your salary slips, bank statements and your Form 26AS / AIS. Ask your employer first if you believe TDS was deducted.
Form 16 vs Form 16A — what's the difference?
Form 16 is the TDS certificate for salary income. Form 16A is the TDS certificate for income other than salary — for example interest or professional fees. Both are TDS certificates, but they cover different kinds of payments.
The tax in my Form 16 does not match Form 26AS. What do I do?
Do not ignore it. A mismatch can mean the deductor has not deposited or reported the TDS correctly. Raise it with your employer/deductor so they can correct their TDS return. Filing with wrong figures can lead to a notice. See our Form 26AS/AIS/TIS and TDS guides for how to reconcile.
