Tax Liability Insurance for Indian M&A: Known Risk Cover, Contingent Liability, and Claim Mechanics

Tax liability insurance (TLI) is often confused with the tax warranty section of a W&I policy, but the two products address different risks. W&I tax warranties cover unknown tax breaches: items that the acquirer does not know about at signing and that would violate a warranty given by the seller. TLI covers specific tax positions or contingent tax exposures that both parties know about (or strongly suspect) and that the acquirer wants to ring-fence through insurance rather than absorb or negotiate a seller indemnity.

The distinction matters because W&I policies explicitly exclude known risks. If due diligence identifies a pending transfer pricing assessment with a potential exposure of INR 80 crore, the W&I underwriter will exclude that matter from cover. The acquirer must either accept the risk, demand a seller indemnity (which the seller may resist, particularly on a clean-exit deal), or purchase a TLI policy that ring-fences the specific exposure. TLI operates as a surgical product, sitting alongside W&I in the deal insurance stack to address identified risks that W&I is structurally unable to cover.

TLI has been used in Indian M&A since approximately 2017, initially for cross-border deals involving Indian targets where international acquirers wanted to ring-fence Indian tax exposures. The product has since grown in domestic use as Indian acquirers become more sophisticated about risk allocation. Industry broker data suggests that 15 to 20 percent of W&I placements in India now include a companion TLI policy or a specific tax indemnity arrangement, up from under 5 percent in 2019.

The TLI product comes in two variants. The first is known-risk cover, also called specific tax risk cover, which addresses an identified tax position. The second is contingent tax liability cover, sometimes called unknown-unknown cover, which addresses the possibility that a tax exposure not currently quantified could emerge during a defined window post-closing. Both variants are offered by the same insurers that underwrite W&I, including Tokio Marine HCC, AIG, Chubb, Liberty, and specialist Lloyd's syndicates, typically placed through Singapore or London paper with Indian brokers coordinating local input.

For Indian acquirers working through a deal, the decision tree runs as follows. If due diligence surfaces a specific material tax risk, assess whether to accept, negotiate a seller indemnity, or insure. If insured, structure a known-risk TLI. Separately, for tax areas where Indian regulation is actively evolving (GAAR, POEM, section 56(2)(viib) reforms, transfer pricing enforcement), consider contingent tax liability cover to protect against unanticipated exposure even where no specific risk has been identified.

A known-risk TLI policy begins with an identified tax position that the acquirer wants to insure. The position may be an ongoing assessment (a notice has been issued under section 143(2) or a draft order exists under section 144C), an appellate proceeding (the matter is pending before CIT(A), ITAT, High Court, or Supreme Court), a position taken in a filed return that could be challenged on reassessment, or a structural arrangement whose tax consequences may be questioned under anti-avoidance provisions.

The underwriting process for known-risk cover differs materially from W&I. Where W&I underwriting relies on the acquirer's due diligence reports, TLI underwriting requires a separate tax counsel opinion on the insured position. The opinion must come from a recognised tax advisor, typically a Big Four accounting firm tax partner or a senior tax counsel (Senior Advocate at a High Court or ex-ITAT member practising privately). The opinion must conclude that the insured position is more likely than not (MLTN) to succeed, meaning greater than 50 percent probability of the position being sustained through final appellate adjudication. Some underwriters accept a should level opinion (approximately 70 percent probability) at a premium discount, but MLTN is the base standard.

The opinion must address specific issues. The factual matrix underlying the position, including all documents supporting the factual assertions. The legal and regulatory framework governing the issue, including recent judicial decisions. The specific arguments for and against the position. A probability assessment that gives a reasoned view on likelihood of success. An analysis of quantum under both adverse and favourable outcomes. Underwriters will often engage their own tax advisor (typically a separate Big Four firm) to review the insured's opinion and form an independent view. This counter-opinion review adds two to three weeks to the underwriting timeline.

The policy is triggered by specific defined events. For Indian known-risk TLI, the typical trigger is the issuance of a final assessment order or appellate order that adversely affects the insured position. For positions already in appellate proceedings, the trigger is a final order from the tribunal or court that crystallises the liability. Some policies also trigger on interim events (a notice under section 148 reopening an assessment, or a reference to the Transfer Pricing Officer under section 92CA), with the trigger being a payment obligation rather than a final adjudication.

The policy period is typically seven years from closing, which covers the standard Indian reassessment window for significant cases and most appellate pathways. For positions already in advanced appellate stages (for example, pending before the Supreme Court), the policy period may be shortened to three to five years reflecting the residual litigation timeline. Premium payment is typically made upfront at closing, though some policies allow spreading over the policy period at a financing cost.

An important feature of known-risk cover is that the insurer agrees specific opinion-based underwriting exclusions rarely. The opinion itself defines the scope of what is covered. Where the opinion assumes certain facts (for example, that transfer pricing documentation exists and supports the arm's length nature of the transaction), the policy is contingent on those facts being correct. Misrepresentation of the underlying facts during opinion development can void coverage.

Contingent tax liability cover addresses the tax equivalent of the unknown unknown. Unlike known-risk TLI that ring-fences a specific identified position, contingent TLI provides coverage for tax exposures that may arise during a defined post-closing window without requiring the acquirer to identify those exposures in advance. The product is narrower than it sounds, with significant exclusions and limits, but it fills a genuine gap for Indian acquirers concerned about future regulatory or enforcement developments.

Contingent TLI policies typically cover tax liabilities arising from: reassessment under section 147 of income-tax returns for periods ending before closing, transfer pricing adjustments under sections 92 to 92F for transactions occurring before closing, GST input tax credit reversals based on vendor non-compliance for supplies received before closing, TDS short-deduction orders for the pre-acquisition period, and customs classification disputes reopened for pre-acquisition imports. The common thread is that the economic activity generating the exposure occurred pre-closing, but the tax authority action triggering liability occurs post-closing.

Coverage is subject to important exclusions. Known positions excluded during due diligence are excluded from contingent TLI (forcing the acquirer to use known-risk cover for those positions). Fraud by the target or its officers is excluded. Change in law applying retrospectively to pre-closing periods is sometimes excluded, sometimes covered, and represents a key negotiation point particularly in the Indian context where retrospective tax amendments have occurred (notably the 2012 retrospective amendment on indirect transfers following Vodafone and the 2021 partial rollback). Penalty and prosecution exposures are typically excluded or sub-limited.

Policy limits for contingent TLI typically range from INR 50 to 500 crore. Premiums run at 3 to 7 percent of the policy limit, reflecting the broad undefined scope of cover compared to the sharply defined known-risk product. For a INR 100 crore contingent TLI limit, the premium falls between INR 3 crore and INR 7 crore, payable at closing. The retention is typically set at INR 2 to 5 crore per claim, with no aggregate across claim types.

Contingent TLI is most valuable in specific deal types. Acquisitions of Indian companies with significant related-party transactions where transfer pricing enforcement patterns are uncertain. Acquisitions of companies in sectors with active regulatory scrutiny (infrastructure, telecom, pharma, and financial services have all experienced periodic tax enforcement waves). Acquisitions by foreign buyers concerned about indirect transfer tax under section 9(1)(i) on the acquisition itself. Acquisitions structured through complex holding company chains where the seller's pre-closing restructuring may attract future scrutiny.

The product is less valuable for straightforward acquisitions of compliant target businesses in low-enforcement sectors where identified due diligence issues can be addressed through known-risk cover. Indian acquirers should evaluate contingent TLI on a deal-by-deal basis rather than treating it as automatic dealinfrastructure.

Indian tax law contains several provisions that generate substantial TLI demand because the provisions are broad, subjective, or retrospectively applied in practice. Understanding the specific triggers helps Indian acquirers identify which positions warrant known-risk TLI or contingent TLI coverage.

General Anti-Avoidance Rules (GAAR) under sections 95 to 102 of the Income-tax Act 1961 empower tax authorities to disregard or recharacterise transactions that are impermissible avoidance arrangements, defined broadly as arrangements entered into primarily to obtain a tax benefit and lacking commercial substance. GAAR has been applicable since April 2017. Retrospective application of GAAR to pre-2017 arrangements has been contentious, though the statutory framework suggests prospective application. TLI has been used to insure positions where the target used structured acquisition financing, holding company interposition for treaty benefits, or debt-versus-equity characterisation choices that could face GAAR scrutiny. Known-risk cover on a specific GAAR exposure typically requires a tax counsel opinion addressing both the commercial substance and the tax benefit, and insurer appetite is stronger for positions with clear commercial rationale independent of tax outcomes.

Transfer pricing under sections 92 to 92F addresses arm's length pricing of transactions between associated enterprises. Transfer pricing adjustments are among the largest tax exposures for Indian corporate targets, particularly subsidiaries of multinational groups where intra-group service fees, royalties, cost allocation, and financing arrangements all create adjustment risk. Royalty payments for technology or brand licences, intragroup management services, and intragroup financing (both loans and guarantees) generate the most frequent adjustments. TLI is widely used to ring-fence transfer pricing positions where the target has filed a return with a transfer pricing approach that the TPO could challenge on reference under section 92CA. Known-risk cover requires a transfer pricing opinion typically from a Big Four firm's transfer pricing practice, supported by benchmarking studies, economic analysis, and factual documentation.

Indirect transfer tax under section 9(1)(i) Explanation 5 taxes the transfer of shares of a foreign company that derives substantial value from Indian assets. The provision was introduced after the Vodafone matter, retrospectively amended, then partially rolled back in 2021 for pre-2012 transactions. TLI has been used on cross-border acquisitions where the acquirer purchases shares of a non-Indian holding company that indirectly owns Indian assets. The insured position is typically that the transferred entity does not derive substantial value from Indian assets, or that treaty provisions apply to exempt the gain, or that the transaction falls within the 5 percent safe harbour. Known-risk cover on indirect transfer positions is available but typically requires a well-supported opinion addressing the substantial value threshold (50 percent of global value test) and any applicable tax treaty.

Section 50CA and section 56(2)(viib) create fair market value friction points. Section 50CA applies to transfer of unquoted shares and deems the consideration to be the fair market value if the declared consideration is lower. Section 56(2)(viib), the so-called angel tax, treats the excess of share issue price over fair market value as income in the hands of the issuer. Both provisions generate TLI demand where the valuation methodology chosen at deal time could be challenged. Known-risk cover is available with a valuation opinion supporting the adopted methodology, typically under the discounted cash flow method or net asset value method permitted under Rule 11UA.

Place of Effective Management (POEM) under section 6(3) treats a foreign company as Indian-tax-resident if its place of effective management is in India. POEM is particularly relevant for Indian corporate groups with offshore subsidiaries that conduct substantive management activity from India. TLI has been used to insure the non-Indian tax residency of specific offshore entities where the POEM analysis is fact-intensive. Known-risk cover requires a POEM opinion analysing board composition, board meeting location, day-to-day management location, and senior decision-maker location, typically supported by documentary evidence.

Beyond these five headline triggers, TLI is also used for specific issues under the GST regime (classification disputes, input credit eligibility, place of supply questions for services), customs duty classification and valuation, equalisation levy under section 165 of the Finance Act 2016, withholding tax on payments to non-residents, and tax treaty applicability for specific income streams.

TLI policies cover four financial components that together make up the economic loss from a tax dispute. Understanding which components are covered, excluded, or sub-limited in a specific policy drives the true economic value of the cover.

The primary tax liability itself is always covered up to the policy limit. If the insured position fails and an assessment order confirms an adjustment of INR 80 crore in tax, the policy pays INR 80 crore subject to the retention and limit. This is the core function of the cover.

Interest on the tax liability is typically covered. Under section 234B of the Income-tax Act 1961, interest on unpaid advance tax accrues at 1 percent per month from the first day of the assessment year until payment. Under section 234C, interest on deferred advance tax accrues at 1 percent per month. Under section 220(2), interest on unpaid demand accrues at 1 percent per month from the due date of payment. Over a seven-year policy period, interest can represent 60 to 100 percent of the principal tax, so interest cover materially affects the real protection offered. Most policies include interest within the policy limit, meaning tax and interest together are capped at the limit. Some policies include interest outside the limit (on top of the limit), attracting a premium loading.

Penalty cover is more complex. Penalties under the Income-tax Act 1961 vary by provision. Section 270A imposes a penalty of 50 percent of the tax payable on underreported income and 200 percent on misreported income. Section 271C imposes a penalty equal to the TDS not deducted. Section 271AAB imposes penalties on undisclosed income found during search proceedings. Insurers typically cover penalties arising from a bona fide position taken in good faith, with documentary support, that ultimately fails on technical grounds. Insurers typically exclude penalties arising from fraud, wilful misrepresentation, or positions taken without reasonable belief. Some policies sub-limit penalty cover at 50 percent of the primary limit to reflect the moral hazard concern.

Defence costs cover the fees of tax counsel, chartered accountants, and forensic experts engaged to contest the assessment and prosecute appeals. Indian M&A deal scenarios may involve defence costs running to INR 5 to 25 crore over a seven-year appellate journey through CIT(A), ITAT, High Court, and potentially Supreme Court. Most TLI policies cover defence costs within the policy limit by default, with policyholders negotiating to move defence costs outside the limit (on top of the limit) where deal economics justify the additional premium.

Policy limits for known-risk TLI in the Indian market typically range from INR 50 crore for smaller ring-fenced exposures to INR 500 crore for material positions on large deals. The limit should be sized to cover the full estimated exposure including grossed-up interest and penalty components over the expected appellate timeline. Underlimit policies force the insured to absorb excess exposure, while overlimit policies waste premium on unused capacity.

Premiums for known-risk TLI in the Indian market typically run at 3 to 7 percent of the policy limit, higher than W&I rates reflecting the defined adverse selection and the insurer's inability to spread risk across the broad warranty universe. Positions with strong opinion support (should level rather than MLTN level), clear factual foundations, and non-aggressive fact patterns attract rates toward the lower end of the range. Positions with aggressive fact patterns, weak documentation, or adverse recent judicial trends attract rates toward the upper end or are declined.

Indian tax law periodically offers dispute resolution schemes that allow taxpayers to settle pending tax disputes at concessional rates. The Vivad Se Vishwas scheme launched in 2020 (extended by Vivad Se Vishwas 2.0 announced in the Union Budget 2024) allowed taxpayers to settle pending income-tax disputes by paying the disputed tax amount without interest or penalty. Similar schemes have operated under the Sabka Vishwas (Legacy Dispute Resolution) Scheme 2019 for indirect tax disputes. These schemes interact with TLI policies in ways that insured parties should understand before signing.

Most TLI policies include a settlement clause that requires insurer consent before the insured enters into any settlement, scheme participation, or compromise with the tax authority. The rationale is that the insurer bears the economic loss, so the insurer must control economic decisions affecting the loss. If the insured unilaterally participates in a Vivad Se Vishwas scheme and pays the disputed tax, the insurer may refuse to reimburse on grounds of breach of the settlement clause.

In practice, insurers and insureds can usually agree on scheme participation because scheme settlement is typically economically favourable compared to full litigation. A scheme that requires payment of 100 percent of disputed tax without interest or penalty may produce an economic outcome substantially better than the expected outcome of continued litigation (where the insured could face 100 percent tax, 60 to 100 percent interest, and potentially 50 to 200 percent penalty). The insurer saves money by settling early.

The mechanics of scheme participation under TLI typically work as follows. The insured notifies the insurer of the scheme availability and the proposed settlement amount. The insurer reviews the expected outcome of continued litigation against the scheme cost and consents to scheme participation if the scheme is economically favourable. The insured pays the scheme amount and claims reimbursement from the insurer. The insurer reimburses the scheme payment subject to retention. Any residual policy limit may or may not survive, depending on policy wording.

One nuance: Vivad Se Vishwas participation typically forecloses further appellate proceedings on the settled matter. The insured cannot revive the matter later. The insurer's consent to scheme participation must therefore be informed and deliberate. Insured parties should consult the insurer early in any scheme window, not wait until the final day, to allow time for the insurer's tax advisor to review the economics and for consent to be formally documented.

Similar dynamics apply to other settlement options. Settlement Commission proceedings under the Income-tax Settlement Commission (now replaced by the Dispute Resolution Committee and Interim Board for Settlement following the Finance Act 2021) require insurer consent. Advance Pricing Agreements (APAs) under section 92CC that resolve transfer pricing positions prospectively typically require insurer consent where the policy covers historical transfer pricing exposure that an APA would settle. Mutual Agreement Procedure (MAP) proceedings under tax treaties similarly engage insurer consent requirements.

For Indian acquirers and sellers structuring TLI policies, the policy wording on settlement and scheme participation deserves specific attention. Broad consent requirements benefit the insurer, while narrow consent requirements (with pre-approved scheme categories or automatic consent mechanisms for economically favourable outcomes) benefit the insured.

The claim process under a TLI policy has more structure than a W&I claim because the underlying dispute (a tax assessment) follows a defined administrative and appellate pathway. Understanding the claim mechanics helps insured parties deal with the multi-year process from initial assessment to final payment.

Notification is the first step. Most TLI policies require notification within 30 to 60 days of the insured becoming aware of a covered event. Covered events typically include: receipt of a notice under section 143(2) initiating scrutiny assessment for a covered period, receipt of a notice under section 148 reopening an assessment, receipt of a reference to the Transfer Pricing Officer under section 92CA, issuance of a show cause notice under section 74 (GST) or similar GST adjudication triggers, receipt of a draft assessment order under section 144C, or issuance of any other tax authority communication that indicates a potential liability under the insured position.

Prompt notification matters because insurers often have the right to participate in or control the defence. Late notification may result in coverage denial on grounds of prejudice to the insurer's ability to defend. Indian acquirers should implement tax notice protocols at the target post-closing to ensure that any tax authority communication is forwarded to insurance counsel within days of receipt.

Defence control is a key negotiating point. Most Indian TLI policies grant the insurer the right to control the defence, including selection of counsel, strategic decisions on appellate pathway, and settlement authority. Insured parties often negotiate for joint defence arrangements where the insured selects counsel subject to insurer approval and major strategic decisions require mutual agreement. For large policies (above INR 200 crore limit), joint defence is standard. For smaller policies, insurer-led defence is more common.

Payment triggers follow the Indian tax demand and collection process. Under Indian tax law, demand issued after assessment is payable within 30 days, but appellate stay orders are routinely obtained to prevent immediate collection pending appeal. Some TLI policies pay out when the insured is required to make an interim deposit (typically 20 percent of demand) to obtain stay pending appeal. Other policies pay out only upon final adjudication at the ITAT, High Court, or Supreme Court level. The timing of the pay-out has significant cash flow implications for the insured, and should be specified clearly in the policy.

Partial success scenarios are common in Indian tax litigation. An assessment may be partially upheld and partially overturned at ITAT, with further appeals to High Court by both sides. The insurer pays the covered portion of the final quantum, with interest and penalty recalculated accordingly. If the insured wins an appeal and recovers tax paid previously, the insured typically returns the recovered amount to the insurer as subrogation.

Subrogation under TLI is complex. The insurer, having paid the insured's tax liability, may in theory subrogate against the seller under the SPA specific indemnity or against third parties. In practice, subrogation against the seller is limited by the SPA (which typically bars it for insured risks), and subrogation against tax authorities is not legally available. Subrogation against advisors whose opinion was relied on (for example, the tax counsel who provided the MLTN opinion) is theoretically possible but rarely pursued because insurer-advisor relationships in the specialist tax market are valued more highly than individual recoveries.

Indian acquirers who purchase TLI should treat the policy as a long-duration relationship, not a one-time transaction. The seven-year policy period covers multiple appellate stages, potential scheme opportunities, and significant administrative engagement. Appointing a single senior executive or advisor to manage TLI matters across the policy life materially improves claim outcomes and reduces administrative friction.
