How to Read Form 16

Form 16 is the TDS certificate your employer issues for tax deducted from salary. It is the official summary of how much salary they reported, how much tax they deducted, and (in Part B) how they computed that estimate. It is not your income-tax return, and it is not complete if you have interest, capital gains or a second employer.

Use it together with Form 26AS and AIS and income-tax basics.

Part A: the certificate

Part A is generated from the department’s TDS system (TRACES) once the employer has filed TDS returns and deposited tax.

Check:

• your PAN and the employer’s TAN;
• the financial year and period of employment;
• quarterly TDS deposited with challan particulars;
• a receipt / certificate number.

If Part A shows less tax than your payslips, the employer may not have deposited or filed correctly. That is a payroll problem to raise early. You cannot invent a credit the department does not have.

Part B: how payroll did the maths

Part B (the annexure) typically walks from gross salary through exemptions and deductions the employer considered, to taxable salary and tax.

Typical blocks:

• gross salary, perquisites, profits in lieu of salary;
• exemptions payroll allowed (for example HRA, if you claimed it under the regime that permits it);
• standard deduction if they applied it;
• deductions they had proof for (such as declared investments);
• tax on the remainder, including cess, minus rebate if they applied one;
• TDS already deducted.

This is why CTC vs take-home arguments belong in the offer stage, and Form 16 belongs at filing time. CTC will not appear as a line you can file.

Matching the three documents

Work in this order:

1. Payslips — monthly gross, exemptions, TDS.
2. Form 16 — annual totals from that employer.
3. 26AS / AIS — what the department says was deposited against your PAN, plus other information.

If payslip TDS sums to ₹1.2 lakh and 26AS shows ₹1.0 lakh, the missing ₹20,000 is not “rounding”. Ask payroll. If you file using Form 16’s higher credit, processing can reduce it.

AIS may show interest the bank reported. Form 16 will not. Leaving it out is how notices begin.

Regime, proofs and what payroll cannot see

Payroll can only deduct on the proofs you submitted in their window, and on the regime you asked them to use. If you later change regime in the ITR, or you forgot a donation receipt, your return is the place — not a handwritten edit on Form 16.

If you opted for a regime with fewer deductions, Part B may show almost no 80C-style lines. That can be correct.

What Form 16 is not

• It is not proof of your full income.
• It is not a refund order.
• It is not GST.
• It does not fix a wrong PAN used on an FD.

Digital signature: a Form 16 from TRACES / the employer’s system should be verifiable. A blurry photo from a group chat is not a certificate.

Filing checklist

1. All Form 16 PDFs for the year.
2. 26AS and AIS downloaded on the same day you start the return.
3. Interest certificates, capital-gains statements, rent receipts if you claim what the law still allows.
4. Bank account for refund — the one you actually use, with the IFSC on the statement.
5. If numbers clash, pause filing and write to the deductor; do not “average” two documents.
