New ITR-B Form for Tax Assessments: What You Need to Know

Background and Legal Context

Under sections 132 and 132A of the Income-tax Act, authorities may conduct a search or requisition to detect undisclosed income. Post such action, taxpayers must file a special return for the "block period" under section 158BC.

This notification introduces Rule 12AE and Form ITR-B, providing detailed procedural guidelines and a new format to furnish return of income for such cases.

Key Highlights of the Notification

This rule lays down the procedural aspects for filing a return post-search/requisition:

  • Applicability: Applies to searches initiated or requisitions made on or after 1st September 2024.
  • Form: Taxpayers must use Form ITR-B.
  • Verification: Must be verified in the manner specified in the form.

3. New Form ITR-B Structure

The ITR-B is a comprehensive form specifically designed for block period assessments. It includes:

A. General Information

Captures personal/organizational details, PAN, Aadhaar, address, employment status, and nature of entity.

B. Return Filing History

Details of returns filed for each assessment year falling in the block period (Y6 to Y0, and Y+1 if applicable).

C. Breakdown of Undisclosed Income

Block period income is broken into:

  • Head-wise income (Salary, Business, Capital Gains, etc.)
  • Assessment year-wise income
  • Disclosure of income discovered during different phases:
    • Before search
    • From 1st April till search
    • From search till conclusion

D. Nature of Undisclosed Assets/Transactions

Requires specific reporting of:

  • Cash, Bullion, Jewellery
  • Virtual Digital Assets
  • Unaccounted expenses or incorrect claims (deductions, allowances)
  • Specified Domestic and International Transactions

E. Tax Computation

  • Tax is computed at 60% on undisclosed income.
  • Additional Surcharge and Cess apply.
  • Interest under Section 158BFA(1) is also levied.

F. Tax Credits and Payments

Includes separate sections for:

  • Tax already paid but not claimed
  • Advance tax/self-assessment tax
  • TDS/TCS credits claimed
 

Implications for Taxpayers

Greater Accountability and Transparency

The form mandates granular detail, including past returns, pending assessments, provisional incomes, and exact asset disclosures-ensuring traceability and deterring evasion.

Comprehensive Data Capture

Multiple heads of income and breakdowns make this format exhaustive. This helps the department cross-verify with findings during search operations.

Digital Filing Emphasis

Pushes for full digitization via DSC or EVC, aligning with India's e-governance goals.

Strict Tax and Penalty Provisions

Tax at 60% + cess + interest makes the cost of non-compliance heavy. Further, incorrect claims attract scrutiny and reporting.

What Taxpayers Should Do

1. Review Past Returns (Y6 to Y0)

Ensure return history is available and accurate for all relevant years. Cross-check ITRs filed, sections used, income declared, and assessments pending.

2. Maintain Proper Documentation

Books of accounts, agreements, valuation reports, and evidence for claims must be preserved-especially if they form the basis for any declaration in Form ITR-B.

3. Identify All Undisclosed Items

Declare cash, digital assets, gold, foreign accounts, etc., to avoid future complications. Note that undisclosed income on account of international or specified domestic transactions must be reported separately.

4. Ensure Timely Filing Post-Search

Returns must be filed within the time stipulated in the notice under section 158BC, using Form ITR-B.

5. Use E-Filing Portal Carefully

Ensure accurate submission via the Income Tax e-filing portal using DSC or EVC, depending on the category.

Conclusion

CBDT's Notification No. 30/2025 brings robust procedural clarity to the process of block assessment under search and seizure cases. By introducing Form ITR-B and mandatory digital filing, it enforces transparency and compliance. For taxpayers and tax professionals, meticulous documentation and proactive review of income declarations and tax positions are critical.

Failure to comply not only leads to high tax and interest but may also invite penal consequences or prosecution under sections relating to concealment.
