6 reasons you may get income tax notice even after meeting July 31 ITR filing deadline

Filing your income tax return (ITR) before the July 31, 2026 deadline was an important step towards staying tax-compliant. However, submitting your return on time does not necessarily mean that you may not receive an income tax notice. Every year, the Income Tax Department sends notices to taxpayers for various reasons, including mismatches between the information reported in the ITR and the data available with the department.



Here are the six common reasons why you may receive an income tax notice even if you filed your ITR before the July 31 deadline.

Income mismatch

One of the most common reasons for an income tax notice is a mismatch in income details. For example, if the salary reported in your ITR differs from the salary mentioned in Form 16, tax deducted at source (TDS) returns filed by your employer or the information available in your Annual Information Statement (AIS) mismatch, the Income Tax Department may ask you to explain the difference.

Interest income not reported

Many taxpayers forget to include interest earned on savings accounts, fixed deposits (FDs), recurring deposits (RDs) or even income tax refunds. Banks and financial institutions report this information to the Income Tax Department, and it is reflected in your AIS. If the interest income shown in the AIS is missing or only partially reported in your ITR, it may trigger a notice asking you to explain the reason.

TDS/TCS mismatch

Claiming a higher Tax Deducted at Source (TDS) or Tax Collected at Source (TCS) credit than what is reflected in Form 26AS or the AIS can also trigger an income tax notice.

Higher cash transactions

The Income Tax Department receives information about several high-value financial transactions from banks and other reporting entities. If these transactions appear in your AIS but are not supported by the income declared in your ITR, the Income Tax Department may seek an explanation.

Capital gains mismatch

If you have sold shares, mutual funds, property or any other capital asset during the financial year, the details may already be available with the Income Tax Department through brokers, registrars or other intermediaries. Incorrect calculation of capital gains, failure to report the transaction or the omission of taxable gains in the ITR can lead to a notice.
