Features & Modules

Tax Liability Insurance

Our tax liability insurance can help a buyer or seller reduce or eliminate its exposure to a specific, identified risk of a tax-related loss. GTS Tax Liability Insurance shifts the responsibility for tax contingencies from the insured to the insurer—minimizing financial risk and exposures and reducing the friction between buyers and sellers.

Tax Liability Insurance for Sellers: Removing uncertainties from the equation—and the balance sheets.

Post-closing rulings and challenges by tax authorities can prevent the distribution of proceeds while liabilities are determined. Sellers often set aside funds in escrow accounts for up to seven years. GTS Tax Liability Insurance gives sellers peace of mind with a single, calculated insurance premium and can limit each seller’s exposure to one another.

Tax Liability Insurance for Buyers: Optimizing the investment, minimizing the exposure.

M&A deals are a huge investment for buyers. Unknown tax liabilities, pre- or post-closing, can turn a lucrative deal into a financial disaster. GTS Tax Liability Insurance reassures buyers and lenders that outstanding liabilities may be covered.

Features & Modules

Tax Liability Insurance

The global tax system is complex and ever-changing, inherently leading to challenging business decisions for taxpayers and their advisors. Tax liability insurance limits the uncertainty and risk of tax positions – whether in the context of an M&A deal or a strategic position. Tax liability insurance is an efficient risk management tool that protects against identified, supportable tax positions not qualifying for their intended tax treatment.

Why use Tax Liability Insurance?

In the M&A context, uncertain tax positions often lead to tense negotiations that can force the parties to walk away from a deal. With tax liability insurance, buyers can avoid self-insuring the risk or negotiating an indemnity/escrow and sellers can insulate themselves from an indemnity obligation. Regardless of an opinion’s strength, no tax position is free from doubt. Private letter rulings are not always available and can take time and energy to procure. As a result, tax liability insurance is an ideal solution to protect against a tax position not qualifying for its intended treatment.

Extent of coverage

Subject to certain terms and conditions and satisfactory underwriting, tax insurance policies provide coverage for the tax owed, any associated interest, fines or penalties, and the costs related to defending the position. Coverage may also include a ‘gross-up’ to compensate for any income taxes assessed on the receipt of the insurance proceeds.

  • Coverage for tax owed
  • Coverage for associated interest, fines, or penalties
  • Coverage for costs related to defending the position
  • Coverage may include a ‘gross-up’ for income taxes on insurance proceeds

Frequently Asked Questions

What are the typical costs and pricing models for Tax Liability Insurance in the USA?
The cost of Tax Liability Insurance typically depends on the nature and complexity of the tax position, deal size, and the specific risks involved. For high-value transactions, such as those overseen by AIG or Liberty GTS, pricing might be calculated as a percentage of the indemnified amount, usually ranging from 1% to 5%. Additionally, firms like Euclid Transactional offer competitive rates reflecting the deal speed execution and the involvement of highly rated carrier partners, insuring over $8 trillion in deal values since 2016.
What are key selection criteria when choosing a Tax Liability Insurance provider?
When selecting a provider, consider their underwriting capacity, speed of execution, and the ability to handle complex claims. AIG and Liberty GTS bring scale and speed as part of global M&A platforms, offering up to $100 million per-risk capacity, which is crucial for large transactions. Additionally, the expertise of handling cross-border deals, as demonstrated by AIG's in-house claim support, and the ability to tailor policies, such as Ambridge’s customization for statutes of limitation, are significant criteria.
What industry standards and compliance requirements must Tax Liability Insurance firms adhere to?
Firms must comply with state regulatory requirements regarding insurance underwriting and claims processing. Companies like Chubb align their offerings with global transactional risk standards, minimizing escrow requirements and facilitating cleaner exits. Additionally, compliance with international accounting and tax regulations is crucial, especially when dealing with cross-border transactions, as supported by AIG's bespoke solutions for complex deals.
What are common implementation challenges of Tax Liability Insurance and how are they addressed?
Challenges include accurately assessing the contingent tax risk and integrating insurance coverage into the transaction timeline. Ambridge and Euclid Transactional mitigate these by offering multi-year policies and deal-speed execution, respectively, ensuring that policies match the statutes of limitation and address uncertainties swiftly. Moreover, Chubb leverages its global transactional risk suite to overcome operational hurdles, providing comprehensive coverage for known exposures.
How does Tax Liability Insurance deliver ROI and value to organizations?
Tax Liability Insurance provides significant ROI by safeguarding against unexpected tax liabilities, thus preserving deal value and facilitating M&A transactions. For instance, AIG's bespoke solutions for tax positions, including U.S. renewable energy credits, help clients transfer risk effectively. Liberty GTS and Euclid Transactional enhance value by shifting tax contingencies from buyers or sellers to insurers, enabling smoother transactions and reducing the need for large escrows, ultimately facilitating cleaner exits for sellers.
