How to Use Form 16 to File ITR: Complete Step-by-Step Guide for Salaried Employees (FY 2025-26)

If you are a salaried employee in India, knowing how to use Form 16 to file ITR is one of the most important financial skills you need every year. With the ITR filing deadline of July 31, 2026 approaching fast, millions of salaried taxpayers are now receiving Form 16 from their employers. But simply having Form 16 is not enough — you need to understand what it contains, how to verify it, and how to use it correctly to file your income tax return without errors or tax notices.

This comprehensive guide explains exactly how to use Form 16 to file ITR step by step, covering everything from understanding its two parts to cross-checking it with Form 26AS and AIS, avoiding common mistakes, and completing your ITR filing smoothly on the Income Tax e-filing portal.

What Is Form 16? A Quick Overview

Before diving into how to use Form 16 to file ITR, you must understand what this document actually is. Form 16 is a TDS (Tax Deducted at Source) certificate issued by your employer under Section 203 of the Income Tax Act, 1961. It is proof that your employer has deducted tax from your salary and deposited it with the Government of India on your behalf.

Every salaried employee whose employer has deducted TDS is legally entitled to receive Form 16 by June 15 of the assessment year. For FY 2025-26 (AY 2026-27), employers must issue Form 16 by June 15, 2026.

Important 2026 Update: Under the new Income Tax Act 2025, Form 16 has been renumbered as Form 130 effective from Tax Year 2026-27 (April 1, 2026) onwards. However, for FY 2025-26, your employer will continue to issue the existing Form 16 as usual. This means the process of how to use Form 16 to file ITR remains the same for FY 2025-26 — nothing changes for this year’s filing. This guide covers everything you need to know about how to use Form 16 to file ITR for the current assessment year AY 2026-27.

Part A and Part B of Form 16 Explained

Understanding both parts is essential when learning how to use Form 16 to file ITR accurately.

Part A — TDS Summary

Part A of Form 16 is generated directly from the TRACES portal (TDS Reconciliation Analysis and Correction Enabling System) maintained by the Income Tax Department. It contains:

Name and address of both employer and employee

PAN of the employee and TAN of the employer

Assessment year and period of employment

Quarterly details of TDS deducted and deposited with the government

Challan or book identification numbers for TDS deposits

Part A is a government-verified document. Any mismatch here with Form 26AS can create problems when you file your ITR.

Part B — Salary and Deductions Breakup

Part B is prepared by your employer and provides:

Gross salary details

Exemptions like HRA (House Rent Allowance) and LTA

Standard deduction of ₹50,000 (or ₹75,000 as updated)

Deductions under Section 80C, 80D, 80E, and other sections

Net taxable income after all deductions

Total tax payable and TDS already deducted

Part B is the most important section when you want to understand how to use Form 16 to file ITR because it directly maps to the income and deduction fields in your ITR form.

Step-by-Step: How to Use Form 16 to File ITR

Here is the complete process for how to use Form 16 to file ITR for FY 2025-26:

Step 1 — Collect and Verify Your Form 16

The very first step in understanding how to use Form 16 to file ITR is to collect it from your employer’s HR or finance department. Once you receive it, do not rush to file immediately. Carefully check:

Your PAN number (incorrect PAN means TDS credit will not reflect in Form 26AS)

Your name and address

Employer’s name, PAN, and TAN

Assessment year (should be AY 2026-27 for FY 2025-26)

TDS amount in Part A matches your payslips

Even a small error in personal details can cause problems in processing your income tax return.

Step 2 — Cross-Check with Form 26AS and AIS

This step is critical for anyone learning how to use Form 16 to file ITR without receiving tax notices later. Log in to the Income Tax e-filing portal (incometax.gov.in) and download:

Form 26AS — Annual tax credit statement showing all TDS deducted against your PAN number from all sources.

AIS (Annual Information Statement) — A comprehensive document that includes additional income sources such as interest income, dividend income, capital gains, and other financial transactions that may not appear in Form 16.

Compare:

TDS shown in Form 16 Part A with TDS in Form 26AS

Income sources in AIS with income declared in Form 16

Any interest income, dividends, or capital gains in AIS that are not in Form 16 must be added separately in your ITR

If there are discrepancies in AIS, report them immediately through the feedback option on the Income Tax portal and retain supporting evidence.

Step 3 — Choose the Correct ITR Form

Knowing how to use Form 16 to file ITR also means choosing the right ITR form:

Most salaried employees with straightforward income will use ITR-1.

Step 4 — Log In to the Income Tax Portal and Start Filing

Go to incometax.gov.in and log in with your PAN as user ID. Navigate to e-File → Income Tax Returns → File Income Tax Return → Select AY 2026-27.

The portal now auto-populates pre-filled data from your AIS and Form 26AS. However, do not blindly trust this pre-filled data. Always verify the pre-filled information against your Form 16 Part B before proceeding.

Go to the Income Tax e-filing portal and log in with your PAN as user ID.

Step 5 — Fill in Salary and Deduction Details from Form 16 Part B

This is the core of understanding how to use Form 16 to file ITR. Use Part B to fill in:

Gross salary from your employer

HRA exemption (if applicable)

Standard deduction

Professional tax paid

Deductions under Section 80C (PPF, ELSS, LIC premium, home loan principal, etc.)

Deductions under Section 80D (health insurance premium)

Any other eligible deductions

Note: If some deductions are not reflected in Form 16 (because you didn’t submit proofs to your employer on time), you can still claim them directly while filing your ITR.

Step 6 — Add Income Not in Form 16

This is a step many salaried employees miss. When learning how to use Form 16 to file ITR, remember that Form 16 only covers your salary income. You must additionally declare:

Savings account interest income (taxable above ₹10,000 under Section 80TTA)

Fixed deposit interest income (fully taxable)

Dividend income

Capital gains from mutual funds or shares

Any freelance or other income

All taxable income including foreign income must be included in your ITR even if it is not in Form 16 or Form 16A.

Step 7 — Choose Your Tax Regime

From FY 2023-24 onwards, the New Tax Regime is the default. When using how to use Form 16 to file ITR knowledge in practice, compare both regimes before selecting:

Old Tax Regime — Allows deductions under 80C, 80D, HRA, etc.

New Tax Regime — Lower slab rates but most deductions not available

The portal will calculate tax under your selected regime automatically. If you have significant deductions, compare both before finalising.

Step 8 — Pay Any Remaining Tax (Self-Assessment Tax)

After filling in all details, if there is any additional tax payable beyond TDS already deducted, pay it as Self-Assessment Tax using Challan 280 before submitting your return. Only file your ITR after this payment is made and challan details are entered in the return.

Step 9 — Submit and E-Verify Your ITR

Submit your return and complete e-verification immediately. E-verification is mandatory — an unverified ITR is treated as invalid by the Income Tax Department. Options include:

Aadhaar OTP (fastest and most common)

Net banking

Bank account EVC

Demat account EVC

DSC (Digital Signature Certificate)

Complete e-verification within 30 days of filing to avoid any issues.

What If You Have Multiple Form 16s?

If you changed jobs during FY 2025-26, you will receive a separate Form 16 from each employer. Here is how to use Form 16 to file ITR in such cases:

Collect Form 16 from all employers

Combine income from all Form 16s in your ITR

Standard deduction cannot be claimed twice — only one ₹50,000/₹75,000 deduction applies

Check that TDS from all employers is reflected in Form 26AS

Provide your new employer with salary details from the previous employer so TDS is correctly calculated

When you change jobs mid-year without informing the new employer of previous salary, each company may independently give you the basic exemption benefit, resulting in lower TDS. This can lead to a tax demand when you file your ITR.

What If You Have Not Received Form 16?

Understanding how to use Form 16 to file ITR also includes knowing what to do if your employer does not issue it. If your employer has deducted TDS but not issued Form 16:

1 .Formally request it from HR or finance department

2 .If still not received, use Form 26AS, AIS, and monthly payslips to file your ITR manually

3 .Your employer is liable for penalties for not issuing Form 16 despite deducting TDS

If no TDS was deducted because your income was below the taxable limit, the employer is not legally required to issue Form 16. You can still file your ITR using your payslips and Form 26AS.

Common Mistakes to Avoid When Using Form 16 for ITR

Even experienced taxpayers make errors. Here are the most common mistakes to avoid when applying how to use Form 16 to file ITR knowledge:

1 Not verifying PAN in Form 16 — Wrong PAN means TDS credit is lost

2 .Ignoring AIS income — Interest, dividends, and capital gains in AIS must be declared

3 .Not combining multiple Form 16s — Leads to underreporting of income

4.Trusting pre-filled data blindly — Always cross-check against Form 16 Part B

5.Missing deductions — Deductions not in Form 16 can still be claimed in ITR

6 .Not paying self-assessment tax before filing — Leads to defective return notice

7 .Skipping e-verification — Unverified return is treated as not filed

Documents to Keep for 6 Years

An important but often forgotten aspect of how to use Form 16 to file ITR is document retention. Keep the following for at least six years:

Form 16 and Form 16A from all employers

Form 26AS and AIS downloads

Investment proofs for 80C deductions

Rent receipts for HRA claims

Bank statements showing interest income

Payslips for the entire financial year
