ITR Filing Mistakes: Common Errors to Avoid While Filing Income Tax Returns

The deadline for submitting income tax returns by individual taxpayers in India is 31 July. It is advisable that you submit your returns well in advance to avoid any mistakes that could happen in a hurry. The income tax department has adopted e-filing of returns in recent years. This has made the process of filing income tax returns more user-friendly. You may file physical returns if your income is below ₹5 lakh p.a., if there are no refund claims or if you are a super senior citizen (anyone aged 80 or over during the preceding year).

When filing income tax returns, there are some common mistakes that may occur. These errors may cause you trouble in the form of notices and penalties levied by the income tax department.

15 Common Mistakes To Avoid When You Are Filing Your ITR

Hold on before you hit submit on that ITR. Some easy-to-miss details could slip through.

Selecting An Incorrect ITR Form

Picking the wrong form is a huge mistake. If your earnings come from salary, interest, or a single house property and stay within ₹50 lakh, ITR-1 (Sahaj) is usually the form to go with. If you are running a business or working as a professional then ITR-3 applies instead.

Before filing anything, take a moment to review Form 26AS. It helps confirm both your income details and the TDS already recorded. If you choose the wrong one, the tax department marks your return as defective. You will then have to start the whole process again from scratch.

Quoting The Wrong Assessment Year

People often mix up the Financial Year (FY) and the Assessment Year (AY). If you earned money in FY 2025-26, your AY is 2026-27. Putting the wrong year on your form is a major blunder. It means your tax data will not match the department's records for that period.

Furnishing Incorrect Personal Or Bank Details

Typos in your name or PAN can cause big gaps in communication. Check your bank account number and IFSC code twice. Your refund goes directly to this account. Also, make sure your bank account is pre-validated on the e-filing portal or the payment will simply fail.

Not Disclosing All Sources Of Income

Only reporting your main salary is a common mistake. You are legally required to declare every single rupee you earn. This includes rent from a spare room, freelance payments, or even small side gigs on weekends. Even if the amount seems tiny to you, hiding it is against the law.

Not Reporting Exempt Income

You’re required to disclose income even when tax doesn’t apply. Think of things like agricultural earnings. Or the amount you receive after a life insurance policy reaches maturity. Reporting these proves your wealth grew legally. It helps you explain big purchases or investments to the tax authorities later on.

Incorrect Reporting Of Capital Gains Or Foreign Income

Investors often fail to report gains from stocks or mutual funds correctly. You must label them as short-term or long-term. Anyone with assets overseas, even just a bank account, has to disclose them through Schedule FA. Forgetting this can lead to massive fines.

Claiming Incorrect Or Ineligible Deductions

It is tempting to claim big deductions to pay less tax. However, you must only claim what you can prove with a receipt. Claiming fake deductions under Section 80C or 80D is very risky. If your case is audited, you will need to show bank statements for everything.

Missing Out On Eligible Deductions

On the other hand, many people forget to claim real benefits. You might miss deductions for health check-ups or money given to charity. Look through all sections of Chapter VI-A carefully. Do not pay more tax than the law actually requires you to pay.

Errors In Reporting Interest Income

A lot of people get confused about how interest is taxed. Section 80TTA allows a deduction, but only up to ₹10,000. This deduction is only applicable on interest earned from savings accounts (bank, post office, or co-operative bank accounts). Interest earned from Fixed Deposits (FDs), Recurring Deposits (RDs), corporate bonds, or other sources is fully taxable. All such interest income must be reported in your tax return, even if Tax Deducted at Source (TDS) has already been applied. Failure To Reconcile TDS With Form 16, Form 26AS, And AIS

Compare your Form 16 with your 26AS tax credit statement. A mismatch in TDS can slow things down, especially when it comes to your refund. It’s worth taking a moment to review your Annual Information Statement (AIS). You might spot something you missed earlier.

Not Paying Advance Tax Or Self-Assessment Tax

If your total tax bill is over ₹10,000 after TDS, you must pay advance tax. If you miss the deadlines, you will face heavy interest charges. Always check your final tax due before you submit the form. Pay any extra gap as self-assessment tax immediately.

Not Verifying ITR After Filing (ITR-V)

Filing the form is just the first step. You must verify it within 30 days. You can use Aadhaar OTP or your net banking for this. If you do not verify the ITR, the department treats it as "Not Filed." All your hard work will go to waste.

Missing The ITR Filing Deadline

The deadline for individuals is usually July 31st. Missing this date results in a late fee of up to ₹5,000. It also stops you from carrying forward business losses to next year. Filing late also means your refund will take much longer to reach you.

Not Revising ITR After Identifying Mistakes

If you find an error after hitting submit, do not panic. The law lets you file a "Revised Return." You should do this as soon as possible before the year ends. Ignoring a known mistake is far worse than taking ten minutes to fix it.

Ignoring AIS Or Not Keeping Proper Documentation

The AIS shows nearly every financial move you made this year. It tracks high-value credit card spends and property deals. Make sure your ITR matches this data. Also, keep your investment proofs and bills safe for seven years in case of an audit.

Conclusion

Filing of income tax returns has come a long way from years ago. The income tax department’s online portal for tax filing has made the process simpler. But first-time taxpayers might still be confused with so many forms and details to be filled in. There are online service providers who try to make the filing process even easier for new taxpayers. In the meantime, remember the points mentioned above while filling out your income tax return forms to avoid these common mistakes.
