- Higher chances of audits
- Poor financial record for loan or visa applications
Let’s explore the common pitfalls you should watch out for, ITR Filing Mistakes
Missing the Due Date
One of the biggest mistakes is missing the ITR filing deadline. For individuals and non-audit businesses, the due date is usually July 31st, while audited accounts have until October 31st.
Tip: Set calendar reminders or engage a tax consultant to stay ahead of the deadline.
Filing Under the Wrong ITR Form
Choosing the incorrect ITR form is another common error. Each form is designated for a specific taxpayer category.
- ITR-1: Salaried individuals (income < ₹50 lakh)
- ITR-2: Individuals with capital gains or foreign assets
- ITR-3: Professionals and business owners
- ITR-4: Presumptive income under Section 44AD/ADA

Not Reporting All Sources of Income
Many individuals forget to include:
- * Interest from savings or fixed deposits
- * Freelance or side gig income
- * Rental income
- * Foreign income or assets (NRI returns)
Non-disclosure can attract scrutiny and fines. Always ensure full income disclosure, even if the amount seems small.

Ignoring Form 26AS and AIS
Your Form 26AS and Annual Information Statement (AIS) provide a consolidated view of your TDS, tax payments, and high-value transactions. Not matching your ITR details with these can lead to discrepancies and notices.
Always cross-check your reported income and TDS with these forms before submission.
Incorrect Bank Details
Mistyped bank account numbers or IFSC codes can delay your income tax refund. Make sure your bank account is active and linked to your PAN to receive timely refunds.
Not Verifying the ITR
Filing your ITR isn’t complete until you e-verify it. If not verified within 30 days of filing, your return will be treated as invalid, ITR Filing Mistakes

Missing out means you pay more tax than necessary. Maintain proper documentation and consult a tax expert to maximize benefits.
