Bad Debt Write-Off: ITAT Ruling 2026 on Section 36(2)(iv) Relief

What Happened?

The Mumbai Income Tax Appellate Tribunal (ITAT) recently delivered an important judgment allowing bad debt deduction to a taxpayer without requiring additional proof of irrecoverability after the debt had already been written off. The tribunal rejected the Assessing Officer's (AO) demand for documentary evidence under Section 36(2)(iv) of the Income Tax Act 2025, and clarified that the transitional four-year rule applicable under that section does not apply to debts already written off in the books.

This ruling provides significant relief to businesses that have already taken bad debt write-offs in their financial statements and accounts.

Background & Legal Context

Section 36(2)(iv) of the Income Tax Act 2025 deals with deduction of bad debts from taxable income. Under this section, a taxpayer carrying on business can claim deduction for debts that are considered irrecoverable during the financial year.

The Income Tax Act 2025 introduced a transitional provision requiring taxpayers to provide proof that a debt is irrecoverable within a four-year period from the end of the financial year in which the debt was incurred. This was meant to tighten compliance and prevent frivolous bad debt claims.

The Key Issue: The question before the tribunal was whether this four-year transitional rule applies to debts that have already been written off in the taxpayer's financial statements and books of accounts before the Income Tax Act 2025 came into force.

Previous Regime (Pre-2025): Under the old Income Tax Act 1961, bad debt deduction was allowed if the assessee could show that the debt became irrecoverable during the year of claim. The burden was on the taxpayer to prove irrecoverability, but once written off, it was not revisited in subsequent years.

The ITAT's Reasoning: The tribunal held that once a debt has been formally written off in the audited financial statements and accounts, it represents a conclusive acknowledgment by the assessee and auditors that the debt is irrecoverable. Therefore, the AO cannot subsequently demand proof of irrecoverability for a second time. To do so would be duplicative and unjust.

Additionally, the tribunal ruled that the transitional four-year rule under Section 36(2)(iv) of the 2025 Act applies only to new claims for bad debt deduction arising after the new act came into force, not to debts that were already written off under the previous regime.

What Does This Mean for You?

For Business Owners & Traders:

• Bad Debts Already Written Off: If you have written off a bad debt in your financial statements before Assessment Year 2025-26, the AO cannot reopen the question during assessment and demand fresh proof of irrecoverability. Your write-off in the books is sufficient evidence.
• Relief from Double Scrutiny: You are protected from being asked to prove irrecoverability twice — once when you wrote it off, and again during income tax assessment. The tribunal's ruling prevents this harassment.
• No Four-Year Retrospective Application: The transitional four-year compliance requirement does not reach back to debts written off under the old regime. This saves many businesses from having to hunt for old documentation.
• Assessment Year 2025-26 Onwards: For bad debts claimed in AY 2025-26 and later, you must ensure you have proof of irrecoverability ready within four years of the end of the financial year in which the debt was incurred — but only for new claims going forward.

For Corporate Houses: Finance departments can confidently rely on audited financial statements as evidence of bad debt write-offs. There is no need to maintain parallel documentation or re-prove irrecoverability at the income tax stage if the auditors have already verified the write-off.

For Professionals & Small Business Owners: If you are in AY 2026-27 and earlier, any bad debts you have already written off in your books are safe from AO scrutiny on the ground of insufficient proof of irrecoverability.

For Lenders, NBFCs & Financial Services: This ruling is particularly important because loan defaults are common in this sector. Once your finance team has written off a loan as a non-performing asset (NPA) and adjusted it in the audited accounts, that write-off is your shield against further proof demands during assessment.

What Should You Do Now?

Action Items for Taxpayers:

• Review Your Last 4-5 Years of Returns: Check if the AO has demanded proof of irrecoverability for debts you had already written off in the books. If yes, you now have strong grounds to challenge such demands under this ITAT ruling.
• Gather Audit Reports: If you are facing assessment queries on bad debts, immediately obtain copies of your audited financial statements and the auditor's notes. These will serve as primary evidence.
• For Pending Assessments: If your assessment is still pending for AY 2025-26, file a strong reply to any bad debt query citing this ITAT precedent. Mention that written-off debts do not require separate proof of irrecoverability at the tax stage.
• For New Bad Debt Claims (AY 2025-26 onwards): Maintain a four-year record of communications with debtors, legal notices, recovery attempts, RBI (for banks/NBFC) classifications, and board resolutions authorizing write-offs. Don't wait until the AO asks — prepare proactively.
• Consult Your Tax Advisor: If the AO has disallowed bad debt deduction citing lack of proof, engage a Chartered Accountant to file a rectification request or appeal citing this recent ITAT judgment.
• File Revised Returns if Applicable: If you have paid excess tax due to disallowed bad debt claims in AY 2024-25 or AY 2025-26, consider filing a revised return (Form 139) within the statutory period to claim relief under this ruling.

Key Takeaways

• Once Written, Always Deductible: A bad debt written off in audited financial statements cannot be challenged on the ground of insufficient proof of irrecoverability under Section 36(2)(iv) ITA 2025.
• Transitional Rule Non-Retrospective: The four-year proof requirement is prospective only and does not apply to debts written off under the old Income Tax Act 1961 regime.
• AO's Powers Limited: The Assessing Officer cannot impose a second layer of proof-gathering once the auditor has already verified and approved the write-off. This protects taxpayers from harassment.
• Documentation Priority for Future: From AY 2025-26 onwards, businesses must maintain contemporaneous records of recovery efforts, legal action, and board approvals for any new bad debt claims to comply with the four-year rule.
• Practical Impact: This ruling provides immediate relief to hundreds of businesses in retail, manufacturing, services, and financial sectors where bad debts are a normal business reality.
