Income mismatch notices have become more frequent in 2025 as the Income Tax Department expands automated cross-verification across Form 26AS, AIS, and TIS. These systems now track interest income, salary variations, capital gains, property transactions, and high-value financial activity reported by banks, employers, and financial institutions. Any inconsistency between reported income and department records is immediately flagged. Even minor differences—such as missed FD interest or an entry mapped to the wrong PAN—can trigger a digital notice. With closer scrutiny and tighter data analytics, accurate reconciliation is essential before filing the ITR. TaxBuddy assists taxpayers by identifying mismatches early and guiding them through precise corrections.
A notice for income mismatch is issued when the income disclosed in the ITR does not match data reflected in Form 26AS, AIS, or TIS. Banks, employers, stockbrokers, and government agencies directly report transactions linked to the PAN, and any gap between those records and the ITR triggers automated scrutiny.

Understanding Why Income Mismatch Notices Are Rising in 2025
Mismatch notices have increased sharply because data collection systems are now fully interconnected. Banks report interest income and high-value transactions under the SFT framework, employers file TDS returns instantly, and investment platforms submit capital gain details in real time. With AI-driven analytics screening every return, mismatches that previously went unnoticed are now automatically flagged. The scrutiny framework for FY 2024-25 and FY 2025-26 places special focus on underreported income, sudden income drops, and inconsistencies across multiple financial sources.
What Is an Income Mismatch Under the Income Tax Act?
An income mismatch occurs when income reported in the ITR differs from the information collected by the Income Tax Department through sources such as Form 26AS, AIS, and TIS. These include salary, interest income, rent, dividends, foreign remittances, securities transactions, property purchases, and cash deposits. When declared income does not match the department’s data, a notice is sent under Section 143(1)(a), Section 139(9), or for detailed scrutiny depending on severity.
Core Reasons for Getting a Notice for Income Mismatch
Several issues commonly trigger mismatch notices:
Missing interest income from fixed deposits, recurring deposits, or savings accounts
Unreported capital gains from stocks, ETFs, mutual funds, NPS, or bonds
Salary differences due to income from a previous employer
TDS amounts not matching due to incorrect PAN reporting
High-value transactions such as deposits above ₹10 lakh or property purchases above ₹30 lakh
Incorrect deduction claims, including overstated HRA or investments
Entries mapped to the wrong taxpayer due to PAN errors in bank systems
Sudden or unexplained drop in income compared to prior years
These gaps are flagged automatically, often within minutes of ITR filing.
How Automated & AI-Driven Scrutiny Detects Mismatches
The 2025 scrutiny process relies heavily on machine learning and pattern recognition. Income reported across sources is compared against historical income patterns, past ITRs, and entries reported by banks and financial institutions. The system identifies anomalies in TDS, unexplained credits, cash deposits, securities trades, and deductions that appear inconsistent with income level. This automated approach reduces manual review and increases the accuracy of detecting discrepancies.
Latest 2025 Updates: Increased Scrutiny and Digital Notices
The department has shortlisted over 1.65 lakh returns for detailed scrutiny in 2025, focusing on income mismatch, inaccurate deductions, and high-value financial activity. Almost all notices are now issued digitally through email and SMS, pushing taxpayers to verify AIS/26AS before filing. Penalties for misreporting under Section 270A and Section 271AAD are stringent, ranging from 50% to 200% of the tax due. Taxpayers are expected to justify discrepancies with proper documentation.
How AIS Collects Data from Banks and Financial Institutions
AIS aggregates data from deductors, banks, SFT filers, stock exchanges, mutual fund houses, GST returns, and government agencies. Each transaction is mapped to a PAN, including interest, dividends, mutual fund transactions, salary information, cash deposits, credit card payments, and property transactions. Even minor errors during account opening—such as a digit mismatch in PAN—can route income to the wrong AIS profile. Delayed bank updates and KYC gaps also contribute to mismatched entries.
Common Bank-Related Errors That Create AIS/26AS Discrepancies
Several bank-level issues often lead to incorrect entries:
PAN misreported during account opening
Joint accounts incorrectly mapped to the wrong primary holder
Interest from dormant or forgotten accounts
FD renewals generating multiple interest entries
Typo in PAN or Aadhaar during KYC
Reporting delays by banks, causing income to appear in a different financial year
These errors lead to unexpected figures in AIS/26AS, which the ITR system treats as discrepancies.
What To Do When Your AIS or 26AS Shows Wrong Entries
If incorrect entries appear:
Verify whether the transaction belongs to an existing or closed bank account.
Raise “Feedback” on the AIS portal using options such as “Information is incorrect” or “Information relates to another PAN.”
Contact the respective bank or financial institution and request correction in their reporting file.
Retain bank confirmation or email proof for submission if the department requests clarification.
Report only actual income in the ITR, not incorrect AIS entries.
Corrections may take time, but updated data ensures accurate scrutiny results.
Steps to Correct Income Mismatches Before Filing ITR A clean reconciliation process reduces the risk of future notices:
Compare Form 26AS, AIS, and TIS with bank statements and investment account summaries
Match interest income across all savings and FD accounts
Verify salary slips against Form 16 from all employers
Reconcile capital gains from brokers with AIS reporting
Review SFT transactions such as cash deposits, credit card payments, and property purchases
Ensure rent receipts, deduction proofs, and investment documents are accurate
Confirm that PAN and KYC details are updated in all financial accounts

FAQs
Q1. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options? TaxBuddy offers both self-filing and expert-assisted plans to suit different types of taxpayers. The self-filing plan provides an AI-driven interface that auto-reads Form 16, imports AIS/TIS data, and helps complete the return with guided prompts. For taxpayers who prefer professional oversight, the expert-assisted plan connects them with qualified tax experts who review income details, verify deductions, reconcile AIS mismatches, and file the return accurately. This dual-approach ensures flexibility, reliability, and error-free filing for every income category.
Q2. Which is the best site to file ITR? The official Income Tax e-Filing portal is the mandated government platform for filing returns. However, taxpayers seeking convenience, accuracy, and automated checks prefer platforms like TaxBuddy that streamline the entire process. TaxBuddy reduces manual entry, identifies mismatches with AIS/26AS instantly, and provides expert-backed review—making it one of the most trusted and user-friendly platforms for filing ITR, especially during peak filing seasons.
Q3. Where to file an income tax return? An income tax return can be filed on the government’s official e-filing portal or through registered private platforms. Many taxpayers choose platforms like TaxBuddy for their AI-driven automation, secure document handling, and expert review features that simplify the filing process. Filing through TaxBuddy ensures accurate reconciliation of income, deductions, and TDS before submission.
Q4. How to avoid getting a notice for income mismatch? Avoiding mismatch notices requires reconciling all sources of income—salary, interest, capital gains, rent, and high-value transactions—with AIS, Form 26AS, and TIS. Updating KYC details in bank accounts, verifying TDS entries, cross-checking broker statements, and accurately reporting FD interest are essential steps. Filing through platforms like TaxBuddy offers automatic mismatch detection, reducing the chances of receiving a notice.
Q5. What should be done if AIS shows an income entry that does not belong to the taxpayer? In such cases, the taxpayer must raise feedback on the AIS portal using options like “Information is incorrect” or “Information relates to another PAN.” Additionally, the concerned bank or reporting institution must be contacted to correct the error in their reporting file. TaxBuddy’s experts guide taxpayers through this process, ensuring corrections are made and the ITR reflects only valid income.
Q6. Does an income mismatch notice always mean additional tax liability? Not necessarily. A mismatch notice simply indicates that the reported ITR information does not align with the department’s records. Sometimes it results from clerical errors, incorrect AIS entries, or TDS reporting issues rather than actual underreporting. With proper explanation, corrected data, or supporting documents, the notice can often be resolved without additional tax. TaxBuddy helps determine whether any tax liability arises and prepares accurate responses.
Q7. Can FD interest or savings interest cause a mismatch notice? Yes, interest income is one of the most common reasons for mismatch notices. Banks report interest amounts to the Income Tax Department, and these entries appear in AIS and 26AS. When taxpayers forget to include interest from FDs, RDs, sweep accounts, or savings accounts, the system automatically flags the difference. Ensuring all interest entries are reconciled prevents such notices.
Q8. Can an error made by the bank or employer result in a mismatch notice? Incorrect PAN mapping, delayed TDS returns, wrong income entries, or duplicate reporting by banks or employers can lead to mismatches. These errors reflect in AIS or 26AS and may trigger notices. Taxpayers must raise AIS feedback and follow up with the reporting entity for correction. Filing with TaxBuddy ensures such discrepancies are identified before the return is filed.
Q9. Is a sudden drop in income compared to previous years a reason for scrutiny? A significant reduction in income, especially without corresponding documentation or explanation, may trigger automated scrutiny. The system compares past ITRs and flags deviations. Providing valid reasons—job changes, reduced business income, or deductions—helps justify the drop. TaxBuddy assists in preparing clear explanations to avoid unnecessary escalation.
Q10. How long does it take to resolve an income mismatch notice? Resolution time depends on the complexity of the mismatch. Minor discrepancies may be resolved within a few days by submitting online clarifications, while cases involving bank errors or employer corrections may take several weeks. Detailed scrutiny cases with multiple mismatches can extend up to a few months. Using TaxBuddy accelerates the process through structured responses and expert coordination.
Q11. Can income mismatch notices be ignored if the difference is small? Even small mismatches should not be ignored. The automated system does not differentiate between minor and major gaps, and unresolved notices can escalate into demand notices or additional scrutiny. Prompt correction and timely response prevent penalties and future complications. TaxBuddy ensures every discrepancy—big or small—is addressed accurately.
Q12. How does TaxBuddy help in resolving income mismatch notices? TaxBuddy’s system identifies all differences between ITR data and AIS/26AS entries through automated reconciliation. Expert professionals review the mismatch, analyse the source of the discrepancy, prepare the appropriate response to the Income Tax Department, and guide the taxpayer through corrections. This combination of automation and expert support ensures accurate resolution and reduces the chances of future mismatch notices.
