Filing an income tax return correctly and on time will help you avoid penalties. It will also help you get any refunds without unnecessary delays. That is why it is important for individual taxpayers to file their taxes before the deadline -31st July of the assessment year.
Note: The due date for filing tax returns for FY 2024-25 (AY 2025-26) is 15th September 2025 for individual taxpayers.
Returns can be filed either manually or online. However, if your income is over Rs.2,50,000 or if you are claiming a refund, filing online is compulsory. This has been the case since the financial year 2016-2017. Under the new tax regime, the limit is Rs.3,00,000. Apart from filing on time, there are other common mistakes that taxpayers end up making every year due to various reasons.

Many taxpayers miss filing their tax returns on time. Missing the deadline can lead to fines. You may also be disqualified from getting your refund if you miss the deadline for filing your Income tax returns.
The wrong ITR form can delay your filing process as you may have to do it again. As mentioned earlier you can be penalised, or it can even cause the rejection of your return. It is important to choose the right form to file your ITR based on your income type.
The Income Tax Department requires complete transparency regarding your financial holdings so failing to disclose all your bank accounts, including foreign ones, can lead to serious legal consequences.
Simple errors like misspelling your name, entering the wrong PAN, or providing incorrect bank details can result in significant delays or rejection of your ITR.
The assessment year is always the year following the financial year. For example, for FY 2023-24, the assessment year is 2024-25. Quoting the wrong assessment year is a common mistake, especially when people confuse the financial year with the assessment year. This could lead to additional taxes or even double taxation.
Many taxpayers neglect to compare their TDS details in Form 16 and Form 26AS, leading to discrepancies. Mismatched information can delay your refund or lead to a higher tax liability.
The Annual Information Statement (AIS) and Taxpayer Information Summary (TIS) provide data on your financial activities during the year. Missing or incorrect data can cause discrepancies in your return.
Some taxpayers fail to report all their income sources, including exempt income or income from secondary sources such as savings accounts or capital gains. This may result in charges of tax evasion.
If you have worked with more than one employer during the year, you may have multiple Form 16s. Failing to consolidate these can result in errors in your income and tax calculation.
Deductions under various sections like 80C, 80D, and 80G reduce your taxable income, but many people fail to utilise these opportunities.
Some employers fail to include House Rent Allowance (HRA) in the Form 16 if rent receipts are not submitted on time, even if you are eligible to claim it.
The interest on National Savings Certificates (NSC) is taxable, but it is often mistakenly believed to be tax-free. Proper reporting is necessary to avoid penalties.
Once you file your ITR, it must be e-verified within 30 days as per the latest CBDT notification. Failure to do so renders the ITR invalid, leading to delays in processing your refund or any further action on your tax return.
Ignoring any communication from the Income Tax Department can lead to serious consequences, such as legal actions or fines.
If your net income exceeds Rs.50 lakh, you must fill out Schedule AL, providing details of your assets and liabilities. Failing to do so can result in penalties or further scrutiny from the tax authorities.
