Even experienced taxpayers often make avoidable mistakes while filing ITR — like mismatched income, incorrect bank details, or skipping TDS credits.
These small errors can lead to refunds being delayed or notices being issued.

Here’s a list of the most common income tax filing mistakes and how you can prevent them this year.

1️⃣ Using the Wrong ITR Form

Filing the wrong form makes your return invalid.
✅ Cross-check your income sources before choosing ITR-1, 2, 3, or 4.

2️⃣ Not Reconciling Form 26AS / AIS

Your total income and TDS must match your Annual Information Statement (AIS).
✅ Always verify before submission.

3️⃣ Forgetting to Report All Income

Include:

• Interest income from banks.

• Dividends or capital gains.

• Freelance or side income.

4️⃣ Claiming Wrong Deductions

Don’t claim deductions without valid proof — e.g., fake 80C receipts can attract penalties.

5️⃣ Not E-Verifying the Return

Unverified returns are treated as not filed.
✅ Verify via Aadhaar OTP, net banking, or bank account.

6️⃣ Missing the Deadline

Late filing = ₹1,000 to ₹5,000 penalty under Section 234F + interest on tax payable.

7️⃣ Forgetting Advance Tax / Self-Assessment

For business or rental income, pay advance tax quarterly to avoid interest (234B/C).

Conclusion

Filing ITR isn’t just about uploading numbers — it’s about accuracy and discipline.
Double-check all details, reconcile data, and verify returns before submission to stay fully compliant.
