ITR Filing 2026: With the deadline for filing Income Tax Returns (ITR) for Assessment Year 2026–27 approaching, many taxpayers are rushing to complete their returns. While filing at the last minute is common, submitting incorrect or incomplete information can lead to delayed refunds, defective returns, or notices from the Income Tax Department.

Before clicking the "Submit" button, it is advisable to carefully review every section of your return. Here is a comprehensive checklist of 10 important points that can help ensure your ITR is filed accurately.

1. Verify Your Personal and Contact Details

Begin by checking all your personal information, including:

• Full name
• PAN
• Aadhaar number
• Date of birth
• Mobile number
• Email address

Updated contact details are essential because the Income Tax Department uses them to send important alerts, notices, and refund-related communications.

2. Choose the Correct ITR Form

Selecting the right ITR form is one of the most important steps in the filing process.

Generally:

• ITR-1 (Sahaj): Suitable for most salaried individuals with eligible income sources.
• ITR-2: Applicable to individuals with capital gains, foreign assets, or other specified income where business income is not involved.
• ITR-3 and ITR-4: Intended for taxpayers with business or professional income, subject to eligibility conditions.

Choosing the wrong form may result in your return being treated as defective, requiring corrections and re-filing.

3. Match Form 16, Form 26AS and AIS

Before filing, compare the information available in:

• Form 16
• Form 26AS
• Annual Information Statement (AIS)

Ensure that salary income, TDS credits, bank interest, dividends, securities transactions, and other reported information match across all records. Any discrepancy should be resolved before submission.

4. Report Every Source of Income

Do not limit your return to salary income alone.

Include all applicable sources of income, such as:

• Savings account interest.
• Fixed Deposit (FD) interest.
• Dividend income.
• Rental income.
• Freelance or consulting income.
• Capital gains from shares or mutual funds.
• Income from Virtual Digital Assets (VDAs), including cryptocurrencies, where applicable.

Failing to disclose taxable income could result in notices or additional tax liability.

5. Verify TDS and Tax Credits

Cross-check that all Tax Deducted at Source (TDS) entries appearing in Form 26AS are correctly reflected in your ITR.

Also verify:

• Advance tax payments.
• Self-assessment tax payments.
• Challan details.
• Tax credits available for adjustment.

Incorrect tax credit information may delay refunds or create unnecessary tax demands.

6. Claim Eligible Deductions Correctly

If you are eligible to claim deductions under your chosen tax regime, ensure that they have been entered accurately.

Common deductions may include:

• Investments under Section 80C.
• Health insurance premium under Section 80D.
• Eligible National Pension System (NPS) contributions.
• Home loan interest, where applicable.
• Other deductions permitted under the Income Tax Act.

Make sure your claims are supported by valid documents.

7. Check Bank Account Details

If a refund is due, it will be credited directly to your registered bank account.

Verify:

• Bank account number.
• IFSC code.
• Whether the account has been pre-validated on the Income Tax e-filing portal.

Incorrect banking information may delay or prevent refund processing.

8. Pay Any Outstanding Tax Before Filing

If your return calculation shows any remaining tax liability, pay the self-assessment tax before submitting the return.

After payment:

• Save the challan.
• Enter the challan details correctly in your ITR.
• Confirm that the payment reflects in your tax records.

9. Disclose Foreign Assets and Overseas Income

Resident taxpayers who own foreign assets or earn overseas income must disclose the required information in their Income Tax Return.

This may include:

• Foreign bank accounts.
• Overseas investments.
• Foreign property.
• Income earned outside India.

Failure to report such information can attract penalties under applicable tax laws.

10. Complete e-Verification

Submitting the ITR is not the final step.

Your return must be e-verified within the prescribed time limit (currently 30 days after submission) to complete the filing process.

Common verification methods include:

• Aadhaar OTP.
• Net Banking.
• Electronic Verification Code (EVC).
• Verified bank account.

A return that is not verified within the applicable timeline is generally treated as invalid.

Common Mistakes to Avoid

Before filing, make sure you do not:

• Select the wrong ITR form.
• Omit any source of taxable income.
• Enter incorrect PAN or Aadhaar details.
• Forget to claim eligible deductions.
• Ignore mismatches in Form 26AS or AIS.
• Submit the return without e-verification.

Avoiding these errors can help ensure smoother processing and reduce the chances of receiving notices from the Income Tax Department.

Final Take

As the ITR filing deadline approaches, taking a few extra minutes to review your return can save significant time and inconvenience later. Verifying your personal details, choosing the correct ITR form, reconciling tax documents, reporting all income, checking tax credits, updating bank information, and completing e-verification can help ensure your Income Tax Return is processed smoothly and reduce the risk of delays, defective returns, or tax notices.
