Tamilnad Mercantile Bank (TMB) has received a Notice of Demand for ₹17.75 crore from the Income Tax Department concerning Assessment Year 2016-17. The demand is based on the disallowance of a claim made under Section 36(1)(viia) of the Income Tax Act, a provision related to deductions for bad and doubtful debts.
Appeal Planned, No Material Impact Expected
TMB is contesting the tax demand and intends to file an appeal against the order. The bank has expressed confidence in a favourable outcome and stated that the demand is not expected to materially affect its financial statements.
Understanding the Tax Dispute
The Income Tax Department's action stems from questioning TMB's eligibility or substantiation for deductions claimed under Section 36(1)(viia). This section allows scheduled banks to claim deductions for provisions against loans and advances, helping to bolster financial stability by accounting for potential non-recoveries. While TMB believes the issue will be resolved favorably and without significant financial consequences, adverse rulings in tax appeals can sometimes lead to substantial financial outflows for financial institutions.
Previous Tax Issues and Penalties
This is not the first time TMB has faced significant tax demands. In March 2026, the bank disclosed a ₹204.23 crore demand for Assessment Year 2013-14, also related to a disallowance under Section 36(1)(viia). TMB has also encountered other regulatory actions, including an RBI penalty of ₹39.60 lakh in November 2025 and ₹1.32 crore in March 2024 for compliance breaches. Additionally, the bank incurred a GST penalty of ₹17.88 lakh in January 2026, and in July 2023, the Income Tax department flagged potential reporting violations exceeding ₹2,700 crore.
Investor Implications
Shareholders should be aware of this contingent liability, though the bank currently assesses it as not material. The ongoing appeal process and its potential outcomes will be reflected in the bank's financial statements. Given the recurring nature of such tax disputes, closer scrutiny of TMB's tax provisioning and compliance mechanisms may follow.
Potential Risks
The primary risk is an unfavourable outcome in the appeal, which could require immediate payment or provisioning for the ₹17.75 crore demand. Although TMB expects a favorable resolution, the appeals process could be lengthy and resource-intensive.
Competitive Context
TMB operates in a competitive Indian private banking sector alongside major players such as HDFC Bank, ICICI Bank, Axis Bank, and Kotak Mahindra Bank. These larger institutions typically benefit from established compliance frameworks and scale that help absorb tax-related contingencies.
Key Factors to Monitor
Investors will be watching the progress and final outcome of TMB's appeal against the Income Tax Department's demand. Further disclosures from the bank regarding this matter and management's commentary on tax contingencies during earnings calls will also be important.
