Top 10 Mistakes While Filing ITR AY 2026-27 That Can Trigger an Income Tax Notice
Introduction
Filing an Income Tax Return (ITR) has become much more than a routine annual compliance. With the Income Tax Department using advanced data analytics, Artificial Intelligence (AI), Annual Information Statement (AIS), Form 26AS, Statement of Financial Transactions (SFT), and information received from banks, mutual funds, stock exchanges, and other institutions, even small mistakes in an ITR can trigger an Income Tax Notice.
Many taxpayers believe that if tax has been deducted at source (TDS), they do not need to worry about reporting all their income correctly. However, this misconception often leads to notices, demands, penalties, and unnecessary litigation.
For Assessment Year (AY) 2026-27, taxpayers should be particularly careful while filing their returns. In this article, we discuss the Top 10 Mistakes that commonly result in Income Tax Notices and how taxpayers can avoid them.
1. Not Matching Income with AIS and Form 26AS
One of the most common reasons for receiving an Income Tax Notice is a mismatch between the income reported in the ITR and the information available in AIS and Form 26AS.
AIS contains details of:
Salary Income
Interest Income
Dividend Income
Share Transactions
Mutual Fund Transactions
Property Transactions
Foreign Remittances
High-Value Transactions
If any income appearing in AIS is not disclosed in the return, the Income Tax Department may issue a notice seeking an explanation.
How to Avoid
Before filing your ITR:
Download AIS.
Download Form 26AS.
Reconcile all income entries.
Report any missing income.
2. Non-Disclosure of Interest Income
Many taxpayers report only salary income and forget to disclose interest earned from:
Savings Bank Accounts
Fixed Deposits (FDs)
Recurring Deposits (RDs)
Post Office Deposits
Income Tax Refund Interest
Even if no TDS has been deducted, such interest income remains taxable.
The Income Tax Department receives information directly from banks and financial institutions. Therefore, non-reporting of interest income can easily be detected.
How to Avoid
Collect interest certificates from all banks and include the entire interest income in the ITR.
3. Incorrect Claim of Deductions Under Chapter VI-A
Many taxpayers claim deductions without proper eligibility or supporting documents.
Common deductions include:
Section 80C
Section 80D
Section 80G
Section 80CCD(1B)
Section 80E
Claiming excessive deductions or ineligible deductions may result in scrutiny.
How to Avoid
Ensure that:
Investments are genuine.
Proper receipts are available.
Deduction limits are not exceeded.
Always maintain documentary evidence.
4. Failure to Report Capital Gains
This is currently one of the most scrutinized areas by the Income Tax Department.
Taxpayers frequently fail to disclose:
Sale of Shares
Mutual Fund Redemptions
Property Sales
Gold Sales
Cryptocurrency Transactions
Many assume that if the transaction resulted in a loss, reporting is not necessary. This is incorrect.
Every capital asset transaction should be properly disclosed.
How to Avoid
Prepare a detailed capital gain computation before filing the return and disclose all transactions irrespective of profit or loss.
5. Selecting the Wrong ITR Form
Choosing an incorrect ITR form can make the return defective.
Examples:
Filing ITR-1 despite having capital gains.
Filing ITR-1 despite foreign assets.
Filing ITR-4 despite ineligibility under presumptive taxation.
A defective return may lead to notices and additional compliance requirements.
How to Avoid
Choose the ITR form strictly according to the nature of income and taxpayer category.
6. Ignoring Dividend Income
Many investors forget to disclose dividend income received from:
Listed Companies
Mutual Funds
Foreign Investments
Since companies report dividend payments to the Income Tax Department, such omissions are easily traceable.
How to Avoid
Verify dividend details from:
AIS
Demat Statements
Broker Statements
Report the entire dividend income in the return.
7. Claiming Incorrect TDS Credit
A frequent mistake involves claiming TDS credit that does not appear in Form 26AS.
Examples include:
Employer has not deposited TDS.
Wrong PAN reported.
Duplicate TDS claim.
Such mistakes often result in tax demand notices.
How to Avoid
Claim only the TDS that appears in Form 26AS and reconcile all TDS entries before filing.
8. Not Reporting High-Value Transactions
The Income Tax Department receives information regarding high-value transactions such as:
Cash Deposits
Credit Card Payments
Property Purchases
Foreign Travel
Investment Transactions
If such transactions are inconsistent with the income declared in the ITR, scrutiny may be initiated.
Example
A taxpayer reports income of ₹5 lakh but purchases a property worth ₹60 lakh.
Such a mismatch may trigger departmental inquiry.
How to Avoid
Ensure that all major transactions can be properly explained through disclosed income and legitimate sources of funds.
9. Incorrect Reporting of Business or Professional Income
Business owners and professionals often make mistakes such as:
Under-reporting turnover.
Claiming excessive expenses.
Incorrect presumptive taxation calculations.
Failure to disclose GST turnover.
The Income Tax Department increasingly compares:
GST Returns
TDS Returns
Bank Transactions
Income Tax Returns
Any significant discrepancy may result in notice issuance.
How to Avoid
Maintain proper books of accounts and reconcile turnover with GST records before filing the return.
10. Failure to Verify the Return After Filing
Many taxpayers file the ITR but forget to verify it.
An unverified return is treated as invalid.
Verification can be completed through:
Aadhaar OTP
Net Banking
Bank Account EVC
Digital Signature Certificate (DSC)
How to Avoid
Verify the return immediately after filing and download the acknowledgement for records.
Additional Mistakes That Can Also Trigger Notices
Apart from the above, taxpayers should also avoid:
Non-disclosure of foreign assets.
Incorrect residential status.
Wrong carry forward of losses.
Fake rent receipts.
Bogus donation claims.
Incorrect agricultural income reporting.
Non-disclosure of crypto income.
Mismatch between GST and Income Tax turnover.
What Should You Do If You Receive an Income Tax Notice?
Receiving a notice does not necessarily mean that additional tax is payable.
Taxpayers should:
Read the notice carefully.
Understand the reason for issuance.
Gather supporting documents.
Submit a timely response.
Seek professional advice if required.
Ignoring a notice may result in demand creation, penalties, or assessment proceedings.
Conclusion
The Income Tax Department now has access to extensive financial information through AIS, Form 26AS, SFT reporting, GST data, banking channels, and digital transactions. As a result, even minor errors can trigger scrutiny or notices.
Taxpayers should carefully review their income, deductions, TDS credits, capital gains, and AIS information before filing their returns for AY 2026-27. A properly prepared and reconciled ITR significantly reduces the chances of receiving an Income Tax Notice and ensures smooth processing of refunds.
Filing an accurate return today can save taxpayers from unnecessary litigation, penalties, and compliance burdens in the future.
