Filing your Income Tax Return (ITR) can feel intimidating, but it doesn’t have to be. The real problem comes when small errors slip in — errors that might look harmless but can actually cost you big. From delayed refunds to unnecessary penalties, these ITR mistakes can leave your wallet lighter than you expected.
The good news? Almost all of them are avoidable. By understanding the most common ITR mistakes that could empty your wallet, you’ll be better prepared to file correctly, save money, and stay stress-free this tax season.
Ultimate Guide to Avoiding ITR Filing Mistakes
Filing your ITR isn’t just another year-end formality—it’s your chance to stay financially organized and compliant. But when taxpayers rush through the process or leave it until the last minute, ITR mistakes are more likely to creep in.
From entering the wrong details to skipping deductions, even a tiny oversight can be costly—sometimes through penalties, other times by reducing your refund.
Here are the 7 common ITR mistakes you must avoid.
1. Choosing the Wrong ITR Form
One of the most common ITR mistakes is picking the wrong form. Think of it as trying to use the wrong key for a lock — it simply won’t fit.
The Income Tax Department offers different forms for different income types. A salaried employee might need a completely different form compared to a freelancer, landlord, or someone earning capital gains.
Why it hurts your wallet: Filing with the wrong form makes your return “defective.” This means you’ll have to re-file, face delays, and possibly pay penalties for missing deadlines.
2. Missing Key Information
Another frequent ITR mistake is overlooking or incorrectly filling basic details like bank account numbers, PAN, or even your address. While these seem small, they can hold up your refund or raise red flags.
Why it hurts your wallet: Missing or incorrect information could delay refunds and, in some cases, invite scrutiny from the Income Tax Department.
3. Neglecting Deductions and Exemptions
Would you ever leave free money lying on the table? That’s exactly what happens when you forget to claim eligible deductions and exemptions.
Sections like 80C (PPF, ELSS, life insurance), 80D (health insurance premiums), or HRA exemptions are designed to save you tax. Sadly, many taxpayers either don’t know about them or forget to claim them.
Why it hurts your wallet: Neglecting deductions means you’re paying more tax than necessary — directly reducing your take-home income.
4. Filing After the Deadline
Procrastination is one of the biggest causes of ITR mistakes. The due date for filing is usually July 31 (unless extended). Missing this deadline can attract a penalty of up to ₹5,000 under Section 234F, plus interest on tax due.
Worse, filing late also means you may lose the ability to carry forward certain losses, which could have reduced your future tax burden.
Why it hurts your wallet: Late fees, interest charges, and loss of future tax benefits — a triple blow!
5. Not Verifying Your ITR
Here’s a mistake many taxpayers don’t even realize: submitting your return isn’t the final step. You also need to verify it.
Verification can be done online using Aadhaar OTP or net banking, or offline by mailing a signed ITR-V form to CPC Bengaluru. If you skip this step, your return is considered invalid.
Why it hurts your wallet: An unverified ITR is treated as not filed at all — meaning penalties, delays, and lost refunds.
6. Ignoring Notices from the Income Tax Department
Not all notices mean you’re in trouble — sometimes they’re just asking for clarification. But one of the most dangerous ITR mistakes is ignoring these communications.
By not responding, you risk escalating what might have been a minor issue into a bigger one, with penalties or even legal action.
Why it hurts your wallet: Ignored notices can freeze your refunds, add penalties, or bring on unnecessary legal stress.
Why it hurts your wallet: An unverified ITR is treated as not filed, leading to penalties and loss of benefits.
7. Overlooking Advance Tax Payments
If your total tax liability after TDS is more than ₹10,000 in a financial year, you must pay advance tax in installments. Many people assume their TDS covers everything and forget this step.
Why it hurts your wallet: Missing advance tax payments leads to interest penalties under Section 234B and 234C, which could have easily been avoided.
