15 Common ITR Filing Mistakes That Delay Your Refund or Trigger Tax Notices
Filing your Income Tax Return (ITR) is much easier today than it was a few years ago, thanks to the Income Tax Department's improved e-filing portal. However, thousands of taxpayers still make small mistakes that can delay refunds, generate notices, increase tax liability, or even require filing an updated return.
Whether you're a salaried employee, pensioner, freelancer, business owner, professional, or first-time taxpayer, understanding these common mistakes can save both time and money.
This guide explains the most frequent ITR filing errors, how to avoid them, and what you should verify before clicking the final Submit button.

Why Small ITR Mistakes Become Expensive
Many taxpayers assume that once their return is submitted, the process is complete. In reality, every return is compared against multiple databases including:
- Employer TDS returns
- Banks and financial institutions
- Form 26AS
- Annual Information Statement (AIS)
- Taxpayer Information Summary (TIS)
- Mutual fund transactions
- Stock market transactions
- Property registrations
- GST records (for businesses)
Even a minor mismatch can result in refund delays, additional tax demands, or notices from the Income Tax Department.
Tip:
Always compare your return with your AIS, TIS, Form 26AS and salary documents before submission.
What Happens If Your Return Contains Errors?
| Mistake | Possible Result |
|---|---|
| Wrong income declared | Tax demand or scrutiny |
| Incorrect bank account | Refund failure |
| Ignoring AIS entries | Income mismatch notice |
| Wrong ITR form | Defective return |
| Late filing | Penalty and interest |
| Missing deductions | Higher tax payment |
| Incorrect PAN details | Return processing delay |
Mistake #1 — Choosing the Wrong ITR Form
This is one of the biggest mistakes made by taxpayers every year.
Different categories of taxpayers are required to file different ITR forms. Filing the wrong form may result in the return being treated as defective.
ITR-1
Generally suitable for salaried individuals having simple income.
ITR-2
Applicable where capital gains or multiple income sources exist.
ITR-3 / ITR-4
Used by business owners, professionals and eligible presumptive taxpayers.
Selecting the correct form before starting your return prevents unnecessary notices and processing delays.
Mistake #2 — Not Checking Form 26AS
Many taxpayers directly enter salary or tax deducted from Form 16 without checking Form 26AS.
Form 26AS reflects taxes deposited with the government. If the TDS shown in your return doesn't match Form 26AS, refund processing may get delayed.
Before filing your ITR, compare:
- Employer TDS
- Bank TDS
- Advance tax
- Self-assessment tax
- TCS credits
Mistake #3 — Ignoring AIS (Annual Information Statement)
The Annual Information Statement contains much more information than Form 26AS.
It may include:
Ignoring these entries is one of the most common reasons taxpayers receive mismatch notices after filing.
Mistake #4 — Forgetting Bank Interest
Many taxpayers believe savings account interest is tax-free.
While deductions may be available under applicable provisions, interest income usually needs to be reported appropriately in the return.
| Interest Source | Should be Reported? |
|---|---|
| Savings Account | Yes |
| Fixed Deposit | Yes |
| Recurring Deposit | Yes |
| Corporate Deposits | Yes |
| Post Office Interest | Depending upon applicable provisions |
Mistake #5 — Missing Dividend Income
Companies and mutual funds often credit dividends directly into bank accounts.
Taxpayers sometimes forget to include this income while filing returns because no separate payment reminder is received.
However, dividend transactions generally appear in AIS and may also be reflected through other reporting mechanisms.
Always verify dividend entries before submitting your return.
Mistake #6 — Incorrect Personal Details
Simple typing mistakes can delay refund processing.
| Information | Verify Carefully |
|---|---|
| PAN | Correct spelling and number |
| Name | Should match PAN records |
| Date of Birth | Correct format |
| Email Address | Active email |
| Mobile Number | Working mobile |
| Bank IFSC | Correct code |
| Account Number | Refund-enabled account |
A wrong bank account number is among the most common reasons refunds cannot be credited successfully.

Mistake #7 — Claiming Deductions Without Proper Proof
Many taxpayers claim deductions under various sections without maintaining supporting documents. Although you may not be required to upload every document while filing your Income Tax Return, the Income Tax Department may ask for evidence during verification or assessment.
Claiming deductions that you are not eligible for can result in additional tax demand, interest, or penalties.
| Common Deduction | Documents to Keep |
|---|---|
| Life Insurance Premium | Premium receipts |
| ELSS Investments | Investment statements |
| PPF Contributions | Passbook or deposit receipts |
| Health Insurance | Policy and payment receipt |
| Home Loan Interest | Interest certificate from lender |
| Education Loan | Interest certificate |
Always keep supporting documents safely for future reference, even after your return has been processed.
Mistake #8 — Choosing the Wrong Tax Regime
India currently offers different tax regimes depending on eligibility and applicable rules. Selecting the wrong option without comparing your tax liability may increase the amount of tax you pay.
Many taxpayers simply accept the default option without calculating which regime is actually beneficial.
Before Choosing
- Estimate taxable income
- Calculate eligible deductions
- Compare both tax regimes where applicable
- Understand switching rules
Don't Assume
The lower tax rate does not always mean lower total tax. Deductions and exemptions may significantly affect your final liability.
Mistake #9 — Forgetting Capital Gains
Many taxpayers invest in shares, mutual funds, gold, or property but forget to report capital gains while filing their return.
Even if tax is not immediately payable in certain situations, transactions may still need to be reported according to applicable provisions.
| Asset | May Generate Capital Gain? |
|---|---|
| Listed Shares | Yes |
| Mutual Funds | Yes |
| Property | Yes |
| Gold | Yes |
| Bonds | Yes |
Always download your broker's capital gains statement and reconcile it with your records before filing.
Mistake #10 — Filing Without Verifying the Return
Many taxpayers believe filing is complete once the return is submitted.
However, the return generally needs to be verified through the prescribed verification methods unless processed automatically under applicable procedures.
Important:
An unverified return may be treated as not validly filed if verification is not completed within the prescribed time.
Mistake #11 — Waiting Until the Last Day
One of the biggest mistakes every year is waiting until the filing deadline.
Although the Income Tax portal has become much more stable, last-minute filing increases the chances of:
- Internet connectivity issues
- Heavy portal traffic
- Payment failures
- Banking delays
- Document mistakes
- Missing important information
Early filing also allows you to receive your refund sooner if all information is correct.
Mistake #12 — Ignoring Income From Previous Employers
If you changed jobs during the financial year, you may have received salary from more than one employer.
Many taxpayers accidentally report income from only their latest employer.
This may result in under-reporting of salary income and additional tax demand later.
Mistake #13 — Not Reporting Freelance or Side Income
Income earned through freelancing, consulting, online platforms, commissions, content creation, tuition, or part-time work may also need to be reported according to applicable tax provisions.
| Income Type | Should Be Reviewed During Filing? |
|---|---|
| Freelancing | Yes |
| Consultancy | Yes |
| Online Services | Yes |
| Commission Income | Yes |
| Professional Fees | Yes |
Mistake #14 — Not Updating Bank Account for Refund
Your refund can only be credited to a valid, eligible bank account linked according to the applicable e-filing requirements.
Before filing, verify:
Mistake #15 — Filing Without Professional Review
Simple ITRs may be straightforward, but returns involving business income, capital gains, multiple employers, foreign assets, or complex deductions often benefit from an independent review before submission.
A second review can help identify missing income, incorrect deductions, calculation errors, and reporting inconsistencies.
