ITR Filing 2025: Know the Various Mechanisms Applied by the IT Dept to Verify the Returns

The Income Tax Department employs several verification mechanisms to ensure that the details provided in Income Tax Returns (ITRs) are accurate and compliant with the law. Here’s a breakdown of the various ways the department verifies returns:


🔍 1. Matching with Form 26AS / AIS / TIS

  • Form 26AS: A consolidated tax credit statement showing TDS, TCS, and advance tax.
  • Annual Information Statement (AIS): Gives a detailed view of financial transactions such as:
    • Bank interest
    • Dividend income
    • Share/mutual fund trades
    • Property purchases/sales
    • Foreign remittances
  • Taxpayer Information Summary (TIS): Summarized version of AIS for easier comparison.
  • Purpose: Verifies whether the taxpayer has reported all income correctly.

📑 2. Reconciliation with TDS/TCS Statements (Form 16, 16A)

  • Cross-checks income declared with TDS deducted by employers (Form 16) or other deductors (Form 16A).
  • Any mismatch may lead to intimation notices (u/s 143(1)) or scrutiny.

💻 3. Data Mining & Analytics (Project Insight)

  • Uses AI/ML tools to detect suspicious patterns such as:
    • High-value purchases not matching declared income
    • Sudden increases in deductions or losses
    • Frequent refund claims
  • Integrates data from banks, mutual funds, stock exchanges, etc.

🏠 4. PAN-Aadhaar Linking & Bank Data Access

  • Enables real-time access to:
    • Bank balances
    • High-value transactions
    • Loan EMIs
  • Cross-verification with PAN-based profiling.

🏦 5. SFT (Specified Financial Transactions) Reporting

Entities like banks, mutual fund companies, property registrars, etc., must report transactions above certain thresholds:

  • Cash deposits > ₹10 lakh in a year
  • Credit card bill payments > ₹1 lakh in cash or ₹10 lakh otherwise
  • Property purchases/sales > ₹30 lakh
  • Mutual fund investments > ₹10 lakh
    These are matched with the ITR.

📬 6. Notice Under Section 139(9), 143(1), 143(2), or 148

  • 143(1): Automated mismatch notice based on ITR and Form 26AS/AIS.
  • 143(2): Scrutiny notice requiring deeper inquiry.
  • 148: Reassessment notice if income has escaped assessment.
  • 139(9): Defective return requiring correction.

💬 7. Verification of Bank Accounts and Digital Footprint

  • UPI, net banking, online trading activity, digital wallet usage may be analyzed to check consistency with declared income.

🧾 8. Review of Audit Reports (Form 3CA/3CD/3CEB)

For businesses and professionals subject to tax audit, the department verifies:

  • Turnover
  • Expenses
  • Compliance with TDS/TCS provisions

💼 9. Survey and Search Operations (U/s 133A / 132)

  • In high-risk or suspicious cases, on-site inspections or raids are conducted.
  • Undisclosed income and assets can be uncovered.

🧠 10. Third-Party Information Exchange

  • Collaborations with agencies like:
    • SEBI (for stock market data)
    • RBI (for foreign remittances)
    • Real estate registrars
  • Information is used to verify large asset purchases or overseas holdings.

✅ 11. e-Verification of High-Value Transactions

  • Taxpayers are sometimes asked to e-verify transactions in AIS via the compliance portal.
  • Failure to respond can lead to further action.

🔁 12. Comparison Across Years

  • Year-on-year comparison of:
    • Income
    • Deductions
    • Capital gains
    • Refund claims
  • Unusual variations may trigger scrutiny.
