ITR Filing 2026: Top 5 Mistakes That Can Delay Your Income Tax Refund

With the deadline for filing Income Tax returns (ITR) for Assessment Year (AY) 2026-27 approaching, taxpayers are rushing to submit their returns. Making the filing on time is crucial, but having all the information that you have given accurately is equally important.

If you are making a small mistake you may have to wait for your tax refund, which can delay your tax refund or spark further scrutiny, or it can get you marked as being defective in your return. The Income Tax Department checks the information contained in your ITR with other financial records before refunding it in your ITR and then cross-checks that information with your tax refund information from other financial records.

The five most common mistakes taxpayers must avoid to bring the refund in a timely and effective manner, so the refund is more than just a refund.

1. Entering Incorrect Bank Account Details

Your income tax refund is directly credited to your pre-validated bank account. If you enter the wrong account number, IFSC code, or bank details, the refund transaction may fail.

Before filing your return, make sure:

1. Your bank account is correctly entered.
2. Your account is linked to your PAN.
3. The account is pre-validated on the Income Tax e-filing portal.

Such details can be verified beforehand to avoid a delayed refund.

2. Not Reporting All Sources of Income

Many taxpayers do not include income tax on their salary income, but forget about other taxes.

These may include:

1. Interest earned on savings accounts.
2. Fixed deposit (FD) interest.
3. Rental income.
4. Freelance or consulting income.
5. Capital gain from shares or mutual funds.
6. Other investment income.

The Income Tax Department compares your return with Form 26AS, the Annual Information Statement (AIS), and other financial records. If a mismatch is identified, it will lead to further verification and delay the refund.

3. Choosing the Wrong ITR Form

We need to choose the correct ITR form.

Different ITR forms are available to different groups of taxpayers based on their income sources, business activities, and residential status.

If you file using the wrong form:

1. The problem may be that your return is defective.
2. You may need to submit a revised or corrected return.
3. Refund processing may be delayed until the problem is resolved.

When you are going to select the appropriate ITR form, always verify eligibility.

4. Claiming Incorrect Deductions

Claim only those deductions for which you are genuinely eligible.

If incorrect claims or excessively high deduction amounts are made, then the Income Tax Department will ask you to report them.

Keep supporting documents ready, including:

1. Investment proofs.
2. Life insurance premium receipts.
3. Health insurance receipts.
4. Home loan interest certificates.
5. Education loan certificates.
6. Other eligible tax-saving documents.

In general, these documents do not need to be uploaded while filing the return, but should be saved for further verification in the future.

5. Forgetting to Verify Your ITR

Submitting your return is only the first step.

After filing, you must complete the verification process. Your ITR is not valid without verification, and the Income Tax Department will not process your refund.

You can verify your return through:

1. Aadhaar OTP.
2. Net Banking.
3. Digital Signature Certificate (where appropriate).
4. Other electronic verification methods available on the e-filing portal.

To avoid delays, complete the verification within the prescribed time limit.

Tips for Faster Refund Processing

To increase the chances of getting your refund quickly:

1. Verify your personal information.
2. Ensure your PAN and Aadhaar are linked (if necessary).
3. Match your income with Form 26AS and AIS.
4. Choose the correct ITR form.
5. Report every source of taxable income.
6. Verify your return immediately after filing.

Conclusion

Filing your Income Tax Return accurately is just as important as filing it on time. Simple mistakes like incorrect bank information, unreported income, selecting the wrong ITR form, unsupported deductions, or failing to verify the return can significantly delay your refund.

Taking a few extra minutes to review your ITR before submission can save you from unnecessary delays and ensure that your tax refund is processed smoothly.
