Online Dispute Feedback: Taxpayers have the statutory right to dispute incorrect or duplicate entries directly within the AIS interface on the eFiling portal.

1. Executive Overview and Regulatory Architecture

Over the past three assessment years, the Central Board of Direct Taxes has fundamentally reshaped the tax compliance landscape in India. Gone are the days when individual tax returns were reviewed on an isolated, self declared honor basis with minimal verification. Today, the tax department operates one of the most sophisticated financial data aggregation platforms in the world.

The centerpiece of this ecosystem is Project Insight and the Annual Information Statement. Financial institutions across India, including scheduled commercial banks, non banking financial companies, stock depositories, clearing corporations, mutual fund registrars, and state sub registrars, are legally mandated to transmit periodic Statements of Financial Transactions. When an individual files their Income Tax Return, automated algorithms at the Centralized Processing Centre in Bengaluru execute instantaneous line by line comparisons.

While this system has drastically expanded the formal tax base and eliminated intentional tax evasion, it has also created administrative headaches for honest citizens. Flawed reporting by third party entities, incorrect classification of off market share transfers, duplicate interest entries, and joint bank account confusion routinely trigger automated demand notices. Understanding the systemic mechanics of these reports is the first step toward effective financial protection.

2. Systemic Mechanics: Big Data, SFT Filings, and Algorithm Traps

To comprehend how tax mismatch intimations originate, one must analyze the statutory pipeline through which your financial transactions travel:

Source Reporting: When you purchase shares through a broker, open a fixed deposit, or pay a credit card bill exceeding ₹1 Lakh in cash or ₹10 Lakh electronically, the institutional reporting entity logs the transaction against your PAN and submits an SFT filing under Section 285BA.
Department Data Ingestion: The Directorate of Systems processes these institutional logs and populates your AIS ledger under distinct categories: Salary, Interest, Dividend, Securities Transactions, Real Estate, and Foreign Travel.
Automated Discrepancy Matching: If your ITR discloses ₹25,000 of dividend income, but reporting companies have filed SFT returns indicating ₹48,000, the CPC algorithm flags a prima facie mismatch, calculating unpaid tax and accumulated interest under Section 234B and Section 234C.

3. Structural Comparison: AIS versus Form 26AS versus TIS

Statement Type	Primary Purpose	Information Covered	Legal Status
Annual Information Statement (AIS)	Comprehensive transaction trail for full income transparency.	All financial movements including share sales, foreign remittances, and rent.	Department Intelligence Ledger
Taxpayer Information Summary (TIS)	Summarized taxable value derived after taxpayer feedback.	Category-wise totals used to pre-fill online ITR schedules.	Operational Computation Guide
Form 26AS	Tax credit verification for prepaid and deducted taxes.	TDS by employers and banks, TCS, advance tax, and self assessment tax paid.	Statutory Tax Credit Ledger

4. Capital Gains Slabs and Reporting Guidelines

Capital gains from stock market trading and mutual fund redemptions represent the single largest category of taxpayer mismatches. Reporting entities transmit the gross transaction value, which uninformed taxpayers sometimes misinterpret as pure net profit.

Asset Class	Holding Period Threshold	Long Term Tax Rate	Short Term Tax Rate
Listed Indian Equity Shares	More than 12 Months	12.5% on gains above ₹1.25 Lakh per year	20% Flat
Unlisted Shares and Private Equity	More than 24 Months	12.5% without indexation	Applicable Slab Rate
Specified Debt Mutual Funds	Any Duration (Post 1 April 2023)	Applicable Slab Rate	Applicable Slab Rate

5. Common Mismatch Triggers and Exact Corrective Actions

Discrepancy Scenario	Root Cause	Recommended Feedback	Resolution Action
Joint Bank Account Interest	Bank reports 100% interest under primary holder PAN even if funds belong to secondary holder.	Information Relates to Other PAN	Submit secondary holder PAN and respective share in AIS feedback.
Duplicate Stock Sale Entry	Both the stock exchange and the clearing depository report the same securities transaction.	Duplicate Information	Mark the redundant entry as duplicate with reference to broker contract note.
Cancelled Property Deal	Agreement drafted but cancelled before registration, while token advance was recorded.	Information is Denied	Upload deed cancellation certificate and bank reversal proof.

6. Old Tax Regime versus New Tax Regime Slab Breakdown

Taxable Income Bracket	New Tax Regime (Default)	Old Tax Regime
Up to ₹3,00,000	Nil	Nil (Up to ₹2,50,000)
₹3,00,001 to ₹7,00,000	5% (Fully rebated up to ₹7,00,000 under 87A)	5% up to ₹5,00,000; 20% thereafter
₹7,00,001 to ₹10,00,000	10%	20%
₹10,00,001 to ₹12,00,000	15%	30%
₹12,00,001 to ₹15,00,000	20%	30%
Above ₹15,00,000	30%	30%

Frequently Asked Questions

Question	Answer
Why does AIS show unknown transactions?	Usually caused by reporting entity data entry errors, joint account confusion, or broker reporting trades that were cancelled.
How do I submit online feedback?	Under the AIS portal Services menu, select the entry, click Feedback, and choose reasons like Duplicate or Relates to Other PAN.
What is a Section 143(1) intimation?	An automated preliminary assessment notice issued by the CPC comparing your filed return against system records.
How are dividends taxed?	Dividends are taxed at your applicable income tax slab rate under Income from Other Sources, with 10% TDS on sums over ₹5,000.

Why does my AIS show transactions that I never actually conducted? ×

Mismatches commonly occur due to data entry errors by reporting entities, incorrect PAN linking by third parties, joint account transactions attributed entirely to the primary holder, or cancelled trades reported as executed sales.

How do I submit online feedback if an entry in my AIS is incorrect? ×

Log into the official income tax eFiling portal, navigate to the AIS tab under the Services menu, select the erroneous transaction, click Feedback, and choose options such as Information is not fully correct, Duplicate information, or Information relates to other PAN.

Does submitting AIS feedback automatically change my filed tax return? ×

No. Submitting feedback prompts the reporting entity to verify the entry and updates your Taxpayer Information Summary (TIS). If you need to rectify your declared income, you must file a Revised Return under Section 139(5) or an Updated Return under Section 139(8A).

What is the difference between Form 26AS and the Annual Information Statement? ×

Form 26AS strictly tracks Tax Deducted at Source, Tax Collected at Source, and direct tax payments. The AIS is significantly broader, capturing gross stock trades, mutual fund redemptions, foreign remittances, high value credit card payments, and savings account interest regardless of whether TDS was deducted.

How should I report savings account interest to avoid AIS notices? ×

All savings bank interest credited across all accounts must be declared under Income from Other Sources. Eligible individual taxpayers under the age of sixty can claim a deduction of up to ₹10,000 under Section 80TTA in the Old Tax Regime, while senior citizens can claim up to ₹50,000 under Section 80TTB.

How are dividends from Indian stocks and mutual funds taxed? ×

Dividends are fully taxable in the hands of the investor at their applicable income tax slab rate under Income from Other Sources. Companies deduct 10% TDS under Section 194 if dividend payments exceed ₹5,000 in a financial year.

What should I do if I receive an automated demand notice under Section 143(1)? ×

Do not panic. Carefully review the intimation sheet to identify which specific income head was adjusted. If the department adjustment is erroneous, file an online Rectification Request under Section 154 through the eFiling portal within the stipulated timeline.

How does the tax department verify share trading and capital gains? ×

Stock exchanges, depositories (CDSL and NSDL), and brokers upload daily transaction records directly to the tax department. The department automated algorithms match the gross sale consideration against capital gains reported in Schedule CG of your ITR.

Can I ignore an AIS mismatch if the monetary amount is small? ×

Ignoring persistent mismatches is not advisable. Small discrepancies can accumulate penalty interest under Section 234B and Section 234C, and unresolved differences may lead to scrutiny notices under Section 148A.

Where can retail taxpayers verify authentic department communications? ×

Every authentic notice, intimation, or order issued by the Income Tax Department carries a mandatory Computer Generated Document Identification Number (DIN). Taxpayers can authenticate any letter by entering the DIN on the public eFiling portal.
