Filing an Income Tax Return (ITR) has become easier than ever. However, filing a return accurately still requires careful verification of income, deductions, tax credits, and disclosures.

Every year, thousands of taxpayers receive notices or face refund delays due to simple mistakes that could have been avoided.

Here are some of the most common mistakes taxpayers should watch out for before submitting their Income Tax Return.

1. Filing the Wrong ITR Form

Selecting the wrong ITR form is one of the most common errors. Each form is applicable to different categories of taxpayers based on the nature of income.

Using an incorrect form may result in a defective return.

2. Ignoring AIS and Form 26AS

Many taxpayers rely only on Form 16.

Before filing your return, always compare your income with AIS and verify TDS credits through Form 26AS.

3. Forgetting Interest Income

Interest earned on savings accounts, fixed deposits, recurring deposits, and other bank deposits is taxable unless specifically exempt.

Many taxpayers forget to include this income.

4. Incorrect Reporting of Capital Gains

Capital gains from shares, mutual funds, or property should never be reported based on estimates.

Use broker statements and capital gain reports for accurate computation.

5. Claiming Incorrect Deductions

Only deductions supported by law and proper documentation should be claimed.

Unsupported claims may invite scrutiny.

6. Not Verifying the Return

Filing an ITR is not complete unless it is successfully verified within the prescribed time.

Always check the filing status after submission.

7. Waiting Until the Last Date

Last-minute filing often leads to avoidable mistakes.

Early filing provides sufficient time to resolve mismatches and correct errors before the due date.

Conclusion

An accurate Income Tax Return is not prepared in haste.

It is prepared after careful reconciliation of income, tax credits, deductions, and supporting documents.

A few minutes of verification can save months of correspondence with the Income Tax Department.

Key Takeaway

Accuracy is the most important step in Income Tax Return filing. Always verify before you submit.
