Filing your Income Tax Return (ITR) is a crucial task that many take lightly. As a seasoned tax consultant, I often see taxpayers making common yet avoidable mistakes that can lead to notices from the tax department or, worse, penalties.

For AY 2026-27, let’s dive into practical scenarios that can help you ensure your ITR is checked thoroughly before submission.

Real-World Filing Mistakes

Consider a taxpayer, Mr. Sharma, who earns a salary and has recently sold shares at a profit. He assumed he could file ITR-1 without any issues. However, because he had capital gains exceeding ₹1 lakh, he was required to file ITR-2. When he submitted ITR-1, he received a notice from the tax department asking for a revised return.

Common Notice-Risk Situations

• Mismatched Income Details: If your Form 26AS shows income that isn’t reflected in your ITR, you could be flagged for scrutiny.
• Capital Gains Misclassification: Investors often misclassify short-term capital gains as long-term, leading to incorrect tax calculations.
• Foreign Assets Disclosure: Failing to disclose foreign bank accounts can attract severe penalties.

AIS/Form 26AS Mismatch

The Annual Information Statement (AIS) is a key document that the tax department uses to verify taxpayer data. If Mr. Sharma's AIS reflected capital gains that he didn’t report, his return would be flagged for mismatch. Always cross-check your AIS and Form 26AS before filing.

Classification and Disclosure Mistakes

Many taxpayers overlook the importance of proper classification. For example, a freelancer like Ms. Gupta mistakenly files ITR-1, thinking her income is salary-based, when it actually falls under business income. This could lead to a defective return, requiring her to revise it and answer to a notice.

Understanding Capital Gains

Before you file, confirm whether you’re eligible for presumptive taxation under Section 44ADA. If you have mixed sources of income, seeking a professional review can save you from future hassles.

Ultimately, the key is not just to submit your ITR but to ensure it accurately reflects your financial situation. Avoid falling into the trap of assuming everything is in order. A thorough check can save you from unexpected notices and complications down the line.
