1. Choosing the Wrong ITR Form
One of the most common income tax mistakes is selecting the wrong Income Tax Return form. Each ITR form is designed for specific types of income. For example, ITR-1 is meant for salaried individuals with limited income sources, while people with capital gains or multiple income sources need to file other forms.
Filing the wrong ITR form can make your return defective. In such cases, the Income Tax Department may ask you to revise your return or may even issue a notice. Many taxpayers lose time and peace of mind simply because they did not choose the correct form.
Before filing, you should clearly understand your income sources such as salary, interest, capital gains, rental income, or business income, and then select the appropriate ITR form.
2. Not Reporting All Sources of Income
Many taxpayers believe that if tax has already been deducted at source, they do not need to report that income again. This is a big misunderstanding. All income must be reported in your tax return, even if TDS has been deducted.
Commonly missed income sources include savings account interest, fixed deposit interest, recurring deposit interest, freelance income, consultation fees, dividend income, and capital gains from shares or mutual funds.
Banks, employers, and financial institutions share this data with the Income Tax Department. If your return does not match official records, it can trigger a notice. Declaring complete income ensures transparency and keeps you safe from future issues.
3. Claiming Incorrect or Excess Deductions
Tax deductions help reduce your taxable income, but claiming deductions without proper eligibility or documents can be costly. Many people claim deductions under sections like 80C, 80D, or HRA without checking the limits or conditions.
Some taxpayers also claim deductions twice, once through their employer and again while filing the return. Others enter incorrect amounts or claim deductions for investments that are not eligible.
If the tax department finds incorrect claims, it may disallow the deduction and impose interest or penalties. Always claim deductions only if you are eligible and have proper proof to support them.
4. Ignoring Form 26AS and AIS
Form 26AS and the Annual Information Statement (AIS) are very important documents that show your tax-related financial activity. These include details of TDS deducted, interest income, dividends, high-value transactions, and investments.
Many taxpayers skip checking these statements before filing their return. This can lead to mismatches between the income declared and the income reported by third parties.
Such mismatches often result in delayed processing or tax notices. Reviewing Form 26AS and AIS before filing helps you correct errors in advance and ensures smooth processing of your return.

5. Filing Income Tax Return Late
Late filing of income tax returns is another costly mistake. If you miss the due date, you may have to pay a late fee of up to ₹5,000 along with interest on unpaid taxes.
Late filing can also delay your refund and may prevent you from carrying forward certain losses such as capital losses or business losses. These losses could have helped you reduce tax in future years.
Filing your return on time not only saves money but also gives you peace of mind and faster refunds.
6. Entering Incorrect Bank Account Details
Your income tax refund is credited directly to your bank account. If you enter incorrect bank details such as wrong account number or IFSC code, your refund may fail.
Many taxpayers also forget to pre-validate their bank account on the income tax portal, which leads to refund delays. In some cases, the refund amount goes back to the government, and the taxpayer has to raise a new request.
Always double-check your bank details and ensure the account is active and linked correctly before submitting your return.
7. Errors in Capital Gains Calculation
Capital gains from shares, mutual funds, property, or other assets must be calculated carefully. Errors often happen because taxpayers misunderstand holding periods, tax rates, or indexation benefits.
Short-term and long-term capital gains are taxed differently, and incorrect classification can lead to higher tax payments or notices. Some people forget to include brokerage charges or improvement costs while calculating gains, which affects the final tax amount.
Accurate capital gains calculation is essential to avoid unnecessary tax and scrutiny from the department.

8. Choosing the Wrong Tax Regime
With the introduction of the new tax regime, taxpayers now have the option to choose between the old and new regimes. Many people select a regime without proper comparison.
The new tax regime offers lower tax rates but removes most deductions and exemptions. The old regime allows deductions but has higher tax rates. Choosing the wrong regime can significantly increase your tax burden.
It is always advisable to calculate tax under both regimes and choose the one that offers maximum savings.
9. Not Verifying the Income Tax Return
Filing the return is only the first step. If you do not verify your return within the specified time, it is treated as invalid, as if you never filed it.
Verification can be done easily using Aadhaar OTP, net banking, or electronic verification code. Many taxpayers forget this step and later face penalties for non-filing.
Always verify your return immediately after filing to complete the process properly.
10. Avoiding Professional Help When Required
While online tools make self-filing easy, not all cases are simple. Taxpayers with multiple income sources, capital gains, foreign income, or business income may face complex tax rules.
Avoiding professional help in such cases often leads to errors, missed deductions, or incorrect reporting. These mistakes can result in penalties, notices, and unnecessary stress.
Taking guidance from a qualified tax expert can help you file accurately, save tax legally, and avoid future problems.
