What is ITR?

ITR stands for Income Tax Return, in which the taxpayer discloses all the details related to his income, assets, taxes, losses, refunds, etc. for the relevant assessment year.

Documents Required for Filing ITR

Before filing ITR, there are a few documents and details that you need to gather in order to file ITR.

• PAN and Aadhaar
• Bank Statements
• Form 16
• Donation receipts
• Stock trading statements from the broker platform
• Insurance policy paid receipts related to life and health
• Bank account information linked to PAN
• Aadhaar registered mobile number for e-verifying the return
• Interest certificates from banks

How to File ITR Online?

Before you start, download both your Form 26AS (Tax Credit Statement) and your AIS (Annual Information Statement) from the e-filing portal. Cross-check every entry against your bank statements, Form 16, broker capital gain statements and rent receipts. If any AIS entry is wrong, submit feedback within AIS itself - this preserves your audit trail and prevents notices later.

The step-by-step guide on how to file ITR online for FY 2025-26 through the Income Tax Portal:

Step 1: Log in to the Income Tax Portal

Visit the Income Tax e-Filing portal and click on Login. Existing users can sign in using their PAN (or Aadhaar), password, and captcha code.

If you are filing your return for the first time, click Register and create an account using your PAN, Aadhaar, mobile number, and email ID. Once registration is complete, log in and navigate to e-File > Income Tax Returns > File Income Tax Return to begin the filing process.

Step 2: Select the Relevant Assessment Year and Filing Mode

Choose AY 2026-27 for income earned during FY 2025-26. Select Online as the mode of filing and click Continue.

If you have previously started filing a return but did not complete it, the portal may give you the option to Resume Filing. Otherwise, select Start New Filing to begin a fresh return.

For FY 2025-26, the Income Tax Act 1961 still applies, therefore, we still need to choose the relevant assessment year. The concept of tax year is relevant only for income earned from FY 2026-27 and onwards.

Step 3: Select Your Filing Status

Choose the category under which you are filing the return, such as Individual, HUF, or any other applicable status. Your filing status determines the applicable ITR forms, tax provisions, and reporting requirements. After selecting the correct status, click Continue.

Step 4: Choose the Correct ITR Form

Selecting the correct ITR form is one of the most important steps in the filing process. The form depends on your sources of income, residential status, and whether you have business or professional income.

For example:

• ITR-1 – Salaried individuals with simple income sources
• ITR-2 – Individuals with capital gains, foreign assets, or multiple properties
• ITR-3 – Individuals with business or professional income
• ITR-4 – Taxpayers opting for presumptive taxation under Sections 44AD, 44ADA, or 44AE

Choosing the wrong form may result in your return being treated as defective.

Step 5: Select the Reason for Filing the Return

The portal will ask you to specify why you are filing the return. Select the option that best applies to your situation, such as:

• Total income exceeds the basic exemption limit
• Claiming a tax refund
• Carrying forward losses
• Meeting specific filing requirements due to high-value transactions, foreign assets, or other prescribed conditions

Selecting the correct reason helps ensure accurate processing of your return.

Step 6: Fill in Income, Deduction and Tax Details

Before proceeding, keep important documents handy, such as Form 16, AIS, Form 26AS, salary slips, bank statements, capital gains statements, and proof of deductions. This will help you verify the pre-filled information and ensure accurate reporting of income and tax credits.

Step 7: Review, Submit and E-Verify Your Return

Before submitting, review all the details in your return and ensure the information is accurate. Once validated, submit the ITR.

After filing, you must e-verify your return within 30 days, failing which the return will be treated as invalid. You can e-verify using Aadhaar OTP, Net Banking, Bank Account EVC, Demat Account EVC, or DSC. Alternatively, you can send the signed ITR-V to CPC, Bengaluru.

Your return filing process is complete only after successful verification. Once verified, the Income Tax Department will process your return and issue any eligible refund.

You can calculate your taxes by using ClearTax Income Tax calculator.
