Filing tax returns online has made the process more convenient and efficient. However, taxpayers often make errors that can lead to delays, penalties, or audits. Understanding these pitfalls and taking preventive measures can help you file your returns accurately and on time. This guide explores common mistakes and provides practical tips on how to e file ITR  accurately.

Key Takeaways

  • Accurate tax filing helps avoid penalties, ensures timely refunds, and builds a strong financial record useful for loans, visas, and investments.

  • Mistakes such as choosing the wrong tax regime, providing incorrect personal details, failing to report all income sources, and mismatches in TDS can cause delays, additional tax liability, or legal consequences.

  • Under the old tax regime, taxpayers should claim deductions under Chapter VI-A (such as 80C for investments, 80D for health insurance, and 80E for education loans) to reduce tax liability effectively.

  • Late filing results in penalties, interest on outstanding taxes, and loss of tax benefits, while unverified returns remain unprocessed. It is also necessary to select the correct ITR form based on income sources.

  • Taxpayers with liabilities above ₹10,000 must pay advance tax in installments to avoid interest. 

Understanding the Importance of Filing Taxes Correctly

Before having a look at the common errors people make while filing returns, you must know why you need to go through this process in the first place. The following points elaborate on the need for filing returns correctly and how it can benefit you:

  • Avoids Penalties and Legal Consequences: Filing incorrect or late tax returns can result in penalties, interest charges, or even legal action from tax authorities. Ensuring accuracy helps you stay compliant and avoid unnecessary fines.
  • Ensures Timely Refunds: Errors in tax filing can delay refunds or lead to adjustments by tax authorities. A correctly filed return ensures that any excess tax paid is refunded promptly.
  • Builds a Strong Financial Record: Regular and accurate tax filing helps maintain a transparent financial history, which is beneficial for future financial planning, visa applications, and business growth.

Common Mistakes and How to Avoid Them

Correct filing of income tax returns can minimise the risk of legal complications and ensure that you end up paying the right amount of tax. You should, therefore, stay clear of the following errors:

  1. Failing to Choose the Correct Tax Regime: With multiple tax regimes available, taxpayers often struggle to select the most beneficial one. While the old regime allows multiple deductions, the new regime benefits taxpayers with lower tax rates.
    Choosing between the old and new tax regimes without careful evaluation can lead to unnecessary tax liability. You should, therefore, compare both tax regimes based on your income, deductions, and exemptions. You can also use an online tax calculator or consult a tax expert for more clarity on how to calculate income tax as per the chosen regime.

  2. Providing Incorrect Personal Information Errors in personal details such as name, PAN (Permanent Account Number), Aadhaar number, or bank details can cause processing delays or rejections.
    It is necessary to double-check all personal details before submitting your return. Ensure that your PAN is linked to Aadhaar as mandated by the tax authorities. You should also ensure that your bank details, including the IFSC code, are correct and linked to your PAN.

  3. Incorrect Income Reporting: Failing to report all sources of income, including interest earned from savings accounts, fixed deposits, rental income, or freelance earnings, can result in penalties. Many taxpayers overlook capital gains from the sale of stocks, mutual funds, or real estate, leading to scrutiny by tax authorities.
    Make it a point to gain a thorough understanding of how to calculate income tax and collect income details from all sources. Further, use capital gains statements provided by brokers or mutual fund houses to report gains accurately. Do not forget to disclose foreign income and claim benefits under applicable DTAA (Double Taxation Avoidance Agreement) provisions.

  4. Ignoring Tax Deducted at Source (TDS) Mismatch: If the TDS reported in your return does not match the amount in Form 26AS, your return may be flagged for discrepancies.
    You should verify TDS details against Form 26AS and the Annual Information Statement (AIS) before submission. If any discrepancies are found, inform the deductor and request corrections.

  5. Not Claiming All Eligible Deductions and Exemptions: If you opt for the old tax regime, you can avail of deductions under Chapter VI-A, such as under Sections 80C, 80D, 80E, and more. However, many taxpayers fail to claim these deductions, leading to higher tax liability.
    To avail the benefits under these sections, you should keep track of all eligible deductions, such as investments in PPF, EPF, NPS, health insurance premiums, and home loan interest. It is also recommended to maintain receipts and proof of investment for audit purposes.

  6. Failing to Verify the Return: According to Indian tax provisions, e-verification is essential to complete the tax return filing process. Unverified returns are not processed, leading to penalties for non-filing.
    After filing your return, you should verify it using Aadhaar OTP, net banking, or send a signed physical copy to the Income Tax Department within 30 days of filing.

  7. Missing the Filing Deadline: Section 139(1) of Income Tax Act provides due dates for filing returns for different types of assessees such as individuals, HUF, businesses, and more. These dates are often extended by the government. Missing the due date and late filing can result in penalties, interest on outstanding taxes, and loss of certain tax benefits.You should learn how to e file ITR on time and mark important tax deadlines. File your returns well in advance to avoid last-minute technical glitches or missing the due date.

Overlooking Advance Tax Payments

If your total tax liability exceeds ₹10,000 in a financial year, failing to pay advance tax may attract interest under Sections 234B and 234C. Thus, you must calculate your tax liability periodically and pay advance tax in installments as prescribed by the Income Tax Act.

Choosing the Wrong ITR Form

The Income tax department has provided 7 types of ITR forms depending on the income sources, total taxable income, and type of assessee. Filing your returns using the incorrect Income Tax Return (ITR) form can lead to rejection or incorrect tax assessment.

You must identify the correct ITR form based on your income sources, residency status, and other criteria. You can use the online tax filing portal’s guidance or consult a tax expert if unsure about how to e file ITR form.

You should start by gaining a complete understanding of how to e file ITR.  Next, by being mindful of common pitfalls and taking preventive measures, you can ensure an accurate and hassle-free tax filing experience.

A little caution goes a long way in making your tax filing process smooth and stress-free.
