Filing your Income Tax Return (ITR) might seem like a routine task, but even a small error can lead to big consequences. Whether you’re a freelancer, salaried professional, or business owner, some ITR mistakes can cost you time, money, and peace of mind.
In this blog by Unlock Digi Services, we’ll uncover the 5 most dangerous ITR mistakes that can cause future headaches—and show you how to avoid them.

Why Accuracy in ITR Filing Matters
Every ITR submission becomes part of your financial history. Errors—intentional or not—can trigger scrutiny from the Income Tax Department, attract penalties, and even result in legal notices.
1. Not Reporting All Sources of Income
It’s Not Just About Salary
One of the most common ITR mistakes is failing to disclose secondary sources of income. These include:
- Freelance projects
- Interest from savings accounts or fixed deposits
- Rental income
- Capital gains from investments
Not reporting these can be flagged through AIS (Annual Information Statement) or Form 26AS, both used by the Income Tax Department for cross-verification. Learn more about Form 26AS here (dofollow link).
2. Claiming False Deductions
Overstating 80C Deductions Can Backfire
Section 80C offers deductions up to ₹1.5 lakh, but exaggerating claims under this or other sections (80D, 80G, etc.) without receipts or proof is a red flag.
Common abuse areas:
- Fake donation receipts
- Overstated medical or tuition expenses
- Unverified ELSS or insurance claims
Solution: Only claim what you can back with valid documentation. Remember, falsely claimed deductions can lead to penalties up to 200% of the tax under-reported.
3. Using the Wrong ITR Form
Filing with the wrong form is a silent but damaging mistake. For instance:
- Salaried employees with capital gains must use ITR-2, not ITR-1.
- Freelancers or consultants need to file ITR-3 or ITR-4.
Why it matters: Wrong forms can lead to defective return notices under Section 139(9).
Solution: Refer to this official ITR Form Guide to choose the right form.

4. Not Verifying the ITR After Filing
An Unverified Return = Non-Filing
Yes, you read that right. If you don’t e-verify your return within 30 days, it’s considered invalid—even if submitted on time.
Solution: After filing, verify your return using Aadhaar OTP, net banking, or sending a signed ITR-V to CPC Bangalore.
Pro tip: E-verification is the fastest and safest way to complete the process.

5. Ignoring Previous Year’s Notice or Demand
Unresolved tax demands or notices from past years should never be ignored when filing a new return.
Consequences:
- Your refund may be adjusted against previous dues
- Continued non-compliance can lead to prosecution
Solution: Log in to your income tax portal and check for any pending demands under “e-Proceedings” or “Outstanding Tax Demand.”
