Form 16 Explained — How to Read It and Use It for ITR Filing

What Is Form 16?

Form 16 is a TDS (Tax Deducted at Source) certificate that your employer issues to you every year. It is your primary document for filing an income tax return as a salaried employee. Think of it as a summary of how much you earned, how much your employer deducted as TDS, and how that was deposited with the government.

Employers are required to issue Form 16 by 15 June for the previous financial year. For FY 2025-26, your employer must give you Form 16 by 15 June 2026.

Form 16 Has Two Parts — and Both Matter

Part A — TDS Details

Part A is generated by the TRACES portal (the government TDS tracking system) and contains:

• Employer's PAN and TAN
• Employee's PAN
• Quarter-wise summary of TDS deducted from your salary
• Total TDS deposited with the government

Part A is generated digitally by TRACES — it always has a TRACES watermark and cannot be manually typed by your employer. If someone gives you a Part A without the watermark, it may not be valid.

Part B — Salary Breakdown

Part B is prepared by your employer and contains:

• Detailed breakup of your salary: basic, HRA, allowances, bonus, perquisites
• Exemptions claimed: HRA exemption, LTA, gratuity, etc.
• Deductions your employer considered: 80C contributions they collected proof for (PPF, ELSS, LIC), 80D health insurance
• Net taxable salary after all deductions
• Tax computed by employer, TDS deducted, balance tax if any

Part B is the most important part for filing your ITR — it shows your chargeable income and what tax your employer already withheld.

How to Cross-Check Form 16 with Form 26AS

Before using Form 16 to file your ITR, always cross-check the TDS figures in Part A with Form 26AS (your tax credit statement) available at the income tax portal. The TDS amounts should match exactly. If they do not:

• Your employer may not have deposited TDS on time
• There may be a data entry error in PAN
• The deposit may still be processing

If there is a mismatch, contact your HR or payroll team and ask them to reconcile it via TRACES before you file. Filing with unmatched TDS can lead to a demand notice from the IT Department.

How to Use Form 16 to File Your ITR

1. Check Part A: Note the total TDS amount deposited with the government. This is the tax credit you will claim.
2. Use Part B for income: The figure labelled "Income chargeable under the head Salaries" in Part B is your taxable salary income for the year. Enter this in your ITR.
3. Add unreported income: Form 16 only captures what your employer knew. If you earned interest on FDs, savings account, rental income, or capital gains during the year — you must add these to your ITR yourself.
4. Review deductions: Your employer may not have captured all your 80C investments (especially if you changed jobs or invested late). Add any missed deductions in your ITR if you are filing under the old regime.
5. Claim TDS credit: In the TDS section of your ITR, enter the TDS amount from Form 16 Part A. The portal pre-fills this from Form 26AS — verify it matches.

What If You Have Multiple Form 16s?

If you changed jobs during FY 2025-26, you will receive Form 16 from each employer. Here is what to do:

• Add the taxable salary from both Form 16s together
• Add the TDS from both Part As together
• Be aware that each employer computed tax independently — they did not know about the other's salary. When combined, you may fall in a higher slab and owe additional tax
• You must disclose salary from both employers even if one employer's Form 16 shows ₹0 TDS deducted

A CA is particularly valuable in job-change situations — the combined income calculation and regime choice requires careful computation to avoid a demand notice later.

What If Your Employer Did Not Give You Form 16?

If your employer refuses or fails to issue Form 16, you can still file your ITR using:

• Your salary slips (for income breakup)
• Form 26AS (for TDS deposited)
• AIS (Annual Information Statement) on the income tax portal

Note: If TDS was deducted but not deposited, you must still pay that tax yourself and then seek a refund or compensation from your employer through legal channels. The IT Department will not accept "employer didn't deposit it" as a reason for a shortfall in your TDS credit.

Common Form 16 Errors and How to Handle Them

• Wrong PAN on Part A: Ask employer to file a TDS correction statement with TRACES. Do not file your ITR until this is corrected — the TDS will not appear in your Form 26AS.
• Salary figure different from actual: Use Part B's chargeable salary figure for your ITR, not your gross CTC. Part B already accounts for exemptions.
• Perquisites not included: Employer-provided rent-free accommodation, car, ESOP vesting, etc. should appear as taxable perquisites in Part B. If they are missing, there may be an understatement.

Filing ITR with a CA — What They Check in Form 16

When you share Form 16 with a CA, they do more than just enter the numbers. They verify the regime applied, check that all exemptions are correctly computed (HRA is a common error), flag any TDS shortfall, identify additional income sources you may have missed, and pick the regime that minimises your tax for the year.
