Checklist for Using Tax Treaties in M&A

Tax treaties are a powerful tool for reducing taxes in cross-border M&A deals, but they require careful planning to work effectively. Without proper use, companies risk double taxation, high withholding taxes, and compliance issues. Here’s what you need to know:

• Tax treaties reduce withholding taxes on dividends, interest, and royalties, often lowering rates from 30% to as little as 0-15%.
• Residency and eligibility are key. Companies must meet specific criteria and provide documentation, like Form 8833 in the U.S., to claim benefits.
• Deal structure matters. Stock purchases may preserve treaty benefits, while asset purchases offer flexibility to establish operations in treaty-friendly jurisdictions.
• Post-deal compliance is critical. Maintaining documentation, monitoring changes in tax laws, and avoiding permanent establishment risks are ongoing tasks.

Tax Treaty Basics for M&A Transactions

Tax treaties play a key role in simplifying cross-border tax issues during mergers and acquisitions (M&A). These agreements between countries aim to prevent double taxation and provide clear guidelines for international transactions. A solid understanding of how these treaties work is essential before diving into the specifics of your deal.

What Tax Treaties Do and Why They Exist

The main purpose of tax treaties is to avoid double taxation and curb tax evasion. They often reduce or completely eliminate withholding tax rates on qualifying transactions, making cross-border activities more efficient.

The United States has income tax treaties with over 60 countries, while globally, there are more than 3,000 bilateral tax treaties. Most of these agreements follow standardized models developed by the OECD and the United Nations, which help create consistency in handling cross-border taxation.

Beyond addressing double taxation, these treaties promote international trade and investment by clearly outlining taxing rights. This clarity is especially important in M&A transactions, where multiple jurisdictions might claim the right to tax the same income.

To prevent misuse, treaties include anti-abuse measures known as Limitation of Benefits (LOB) provisions. These provisions are designed to stop "treaty shopping", a practice where companies set up artificial structures or shell entities solely to take advantage of favorable tax treaty terms. LOB provisions ensure that only legitimate tax residents benefit from treaty advantages.

Types of Income That Tax Treaties Cover

Tax treaties primarily address two types of income common in M&A transactions: business income and non-business income.

• Non-business income includes dividends, interest, royalties, and capital gains. In the U.S., these are categorized as Fixed, Determinable, Annual, or Periodical (FDAP) income and are generally subject to a statutory 30% withholding rate. However, tax treaties often lower or eliminate this rate for qualifying transactions, as noted by GHJ Advisors.
• Business income is taxed based on whether a company has a Permanent Establishment (PE) in the other country. If no PE exists, the company’s business profits are typically exempt from taxation in that jurisdiction. For capital gains, treaties often provide favorable terms, such as exemptions or reduced rates, though the specifics vary by agreement. Some treaties even offer full exemptions for certain types of capital gains, while others impose conditions for eligibility.

This distinction between income types is critical for understanding how tax treaties can benefit M&A deals in practical terms.

How Tax Treaties Work in Practice

Tax treaties provide benefits through reduced withholding tax rates and tax credits. For instance, instead of the standard 30% withholding rate, qualifying transactions may see significantly lower rates or even exemptions. Additionally, foreign tax credits allow companies to offset taxes paid in one country against their tax obligations in another.

Residency is a key factor in determining treaty eligibility. For businesses, residency is often based on the place of incorporation, the location of management, or where the company is effectively managed. For individuals, factors like domicile, citizenship, or place of management come into play.

When residency overlaps between two countries, treaties include tie-breaker rules to resolve conflicts. These rules prioritize factors like permanent home, center of vital interests, habitual abode, and citizenship. If these tests don’t resolve the issue, the competent authorities of both countries work together to reach an agreement.

Claiming treaty benefits comes with compliance requirements. For example, taxpayers seeking treaty advantages must file Form 8833 (Treaty-Based Return Position Disclosure) annually with their U.S. income tax returns. This ensures transparency and proper documentation of treaty claims.

It’s important to note that tax treaties typically apply only to federal taxes. State-level tax rules may differ significantly, potentially creating unexpected obligations if not addressed during deal planning. Careful analysis of both federal and state tax implications is essential to structuring an M&A deal that maximizes treaty benefits.

Understanding these tax treaty fundamentals is a critical step in conducting thorough due diligence and structuring transactions to achieve the best possible tax outcomes.

Due Diligence Steps for Tax Treaty Benefits

Thorough due diligence is essential for effectively utilizing tax treaties in mergers and acquisitions (M&A). This process involves a detailed examination of treaty frameworks, entity qualifications, and the target company's tax history. The goal is to structure the deal in a way that delivers the intended tax savings while minimizing risks.

Identify and Review Relevant Tax Treaties

Start by pinpointing the tax treaties that apply to your transaction. Identify the countries where the acquiring and target companies are tax residents, and locate the bilateral tax treaty governing those jurisdictions. This step provides a clear understanding of the treaty framework and the potential benefits it offers. Once the treaties are identified, confirm that both parties meet residency requirements to qualify for treaty benefits.

Confirm Eligibility and Residency Status

Determining residency status requires a review of legal criteria and actual circumstances for each party. For individuals, this means applying the U.S. green card and substantial presence tests. For corporations, confirm domestic status under U.S. law. In cases of dual residency, treaty tie-breaker rules come into play.

Residency rules differ by jurisdiction - some focus on the place of incorporation, while others prioritize the place of effective management. Carefully document the criteria used by each country and gather evidence to support the desired residency classification.

Dual residency cases demand extra care. If an individual or entity qualifies as a resident in both treaty countries, standard tie-breaker rules can resolve the issue. When those rules fall short, the competent authorities of both countries must reach a mutual agreement. Once residency and eligibility are verified, shift focus to the target company's tax history to uncover potential risks.

Check Target Company Tax History

Examine the target company's recent tax returns at the federal, state, and local levels, along with any audit findings. Look for inconsistencies, hidden liabilities, or unresolved permanent establishment issues. Review financial statements and their accompanying notes to understand the company’s tax position, including effective tax rates and uncertain tax provisions.

Pay close attention to any permanent establishment concerns that could affect long-term tax obligations.

Deal Structure Planning for Tax Treaty Benefits

Once you've confirmed treaty eligibility and reviewed the target's tax position, the next step is to structure the transaction in a way that maximizes treaty benefits. How you organize the deal can significantly influence potential tax savings and shape your ongoing compliance responsibilities.

Using insights from your due diligence, you can create a transaction structure that takes full advantage of treaty benefits.

Choose the Right Transaction Structure

Deciding between a stock purchase and an asset purchase is a critical step that directly impacts tax outcomes.

• Stock purchases often allow the target company's existing treaty positions to remain intact. This means you can continue benefiting from the treaty advantages tied to the company’s current residency status, including favorable treaty positions and permanent establishment arrangements.
• Asset purchases, on the other hand, come with their own set of advantages and challenges. While you won't inherit the target's existing treaty benefits, you gain the flexibility to establish the acquiring entity in a jurisdiction with a more favorable treaty network. This can be especially useful if the target's current treaty access is limited or if consolidating operations under a single treaty framework aligns better with your strategy.

Another option to consider is setting up holding company structures. These can be used in treaty-favorable jurisdictions to channel payments and reduce withholding taxes. However, it's crucial to ensure these structures have enough economic substance to avoid violating anti-treaty shopping rules, which could disqualify treaty benefits.

Timing also plays a role in optimizing treaty benefits. For example, staged acquisitions allow you to test treaty positions and refine your transaction structure as you move forward. This phased approach gives you the flexibility to adapt to initial results or changing tax environments.

Once you've settled on the most effective structure, the next priority is minimizing withholding tax expenses.

Minimize Withholding Tax Expenses

Withholding taxes on cross-border payments often represent a major area for treaty-based savings in M&A transactions. Here's how treaties can help:

• Dividend withholding taxes: Treaties often reduce withholding rates on dividends to as low as 0% to 15%, compared to statutory rates that can climb to 30% or more.
• Interest payments: Many modern treaties either eliminate withholding taxes on interest payments entirely or reduce them to 10% or less. This is particularly advantageous when structuring acquisition financing through treaty-friendly jurisdictions.
• Royalty payments: Intellectual property-related royalties often benefit from treaty exemptions or significantly reduced withholding rates. This is especially valuable in technology acquisitions where royalties are a key part of the deal.

Strategically timing payments can also help you take advantage of lower withholding rates. Accelerating or deferring payments, depending on the treaty terms, can further enhance savings. Just ensure that all calculations and claims are well-documented to avoid compliance issues.

Beyond withholding taxes, integrating foreign tax credits into your planning can help avoid double taxation and maximize treaty advantages.

Leverage Foreign Tax Credits and Plan Integration

When treaty benefits don't completely eliminate foreign taxes, foreign tax credits can help offset the remaining tax burden. However, credit limitation rules require careful planning to ensure you can fully utilize these credits.

• Structure income streams to maximize the use of foreign tax credits.
• Pool foreign taxes and income across jurisdictions to optimize credit utilization, especially in acquisitions involving multiple subsidiaries or operations in different treaty countries.
• Keep detailed records to support credit calculations and claims.

Post-merger integration is another area where foreign tax credits require attention. Changes in entity structure, income sourcing, or business operations can affect credit availability. A flexible integration plan can help preserve these tax benefits.

To add an extra layer of certainty, consider negotiating advance pricing agreements with tax authorities. These agreements clarify transfer pricing and foreign tax credit positions, reducing the risk of future disputes and ensuring your treaty planning remains effective over the long term.

Finally, the integration process itself can unlock additional treaty benefits. By consolidating operations, restructuring intellectual property ownership, or realigning financing arrangements, you may discover new opportunities for treaty optimization that weren’t possible before the acquisition.

Post-Deal Compliance and Monitoring Tasks

Wrapping up an M&A deal is just the beginning. The next phase - active post-deal compliance - is critical to preserving treaty benefits. This involves consistent monitoring and careful management to ensure your tax strategy stays effective over time.

Post-deal challenges can quickly undermine treaty advantages. Shifts in business operations, changes in tax laws, and evolving regulations can all jeopardize the treaty positions you worked hard to establish.

Maintain Tax Treaty Compliance Requirements

To keep treaty benefits intact, you’ll need to stay on top of documentation and reporting. A centralized system for tracking all treaty-related documents is a great starting point. This includes keeping residency certificates current, updating beneficial ownership records, and maintaining any supporting documents for your treaty claims. Tax authorities expect precise and up-to-date records throughout the duration of your treaty benefits.

Regular reviews are essential. Check that your business continues to meet treaty requirements, such as substance standards, and verify that all necessary filings are up to date. Be especially vigilant about changes in ownership, management, or business operations that could impact your eligibility for treaty benefits.

Documentation requirements vary by country. While some jurisdictions require annual recertification for treaty positions, others may accept multi-year certifications. To avoid compliance gaps during audits, it’s crucial to have a robust record-keeping system in place. This also helps you stay prepared for shifts in tax laws.

Monitor Tax Law and Treaty Changes

The tax environment is constantly changing, and these shifts can directly impact your treaty benefits. Over 70% of dealmakers view tax risks as a growing concern for M&A success, highlighting the importance of staying informed.

To keep up, use advisory services and local tax experts to monitor legislative changes. Tax laws can change quickly, and some updates may even apply retroactively to past transactions. For instance, the OECD’s Pillar Two and Global Minimum Taxation reforms have been identified by 46% of respondents as likely to affect deal outcomes, with over 50 countries already adopting similar measures.

Recent developments illustrate how quickly things can shift. In February 2024, the IRS announced changes to the status of several U.S. foreign tax treaties. Treaties with Russia and Hungary were removed from the list of "comprehensive" and "satisfactory" agreements, eliminating reduced tax rates for qualified dividend income. Meanwhile, Chile’s treaty was added, offering new opportunities for reduced capital gains taxation.

To stay ahead of these changes, consider subscribing to specialized publications or advisory services that track treaty updates in relevant jurisdictions. Partnering with local tax advisors can also help you get early warnings about proposed changes that might affect your treaty positions.

Handle Permanent Establishment Issues

Operational changes after a deal closes can introduce new risks, particularly around permanent establishment (PE). These risks could lead to unexpected tax obligations and, if not managed carefully, might invalidate your treaty benefits.

Post-merger integration often creates PE exposures that weren’t part of the original deal structure. For example, consolidating operations, relocating key personnel, or centralizing decision-making could unintentionally establish a taxable presence in jurisdictions where favorable treaty terms previously applied.

To manage this, keep a close eye on operational changes. Track the movement of key personnel and monitor business activities in each jurisdiction, paying attention to time thresholds outlined in tax treaties.

If your integration strategy involves centralizing procurement, creating shared service centers, or establishing new service relationships, assess how these changes might alter your PE risk profile. Additionally, for businesses with significant online operations, consider how digital PE rules - based on revenue or user engagement rather than physical presence - might impact your compliance strategy.

Global enforcement trends can also add unpredictability, with increased scrutiny of complex M&A-related tax positions. Regular PE assessments should be part of your compliance routine, considering both current operations and future plans.

Phoenix Strategy Group emphasizes the importance of maintaining clear PE boundaries during post-merger integration. As operations evolve, structural adjustments may be needed to preserve treaty benefits. Viewing tax treaty management as an ongoing process, rather than a one-time task, is key to adapting to the ever-changing international tax landscape.

Common Mistakes and Warning Signs to Avoid

Navigating tax treaties in the context of mergers and acquisitions (M&A) can be tricky, even for experienced professionals. The intricate nature of international tax laws, coupled with the urgency to close deals, often leads to costly mistakes. To steer clear of these pitfalls, it’s crucial to be vigilant throughout the process and ensure treaty benefits are secured properly.

Errors in treaty compliance often come to light during post-deal audits, which can result in hefty penalties and unexpected tax liabilities. In some cases, companies may only uncover these issues years down the line, facing additional taxes, interest charges, and disputes with multiple tax authorities.

Spot Tax Compliance Warning Signs

Certain red flags can signal potential compliance issues in M&A tax treaty claims. Here are key warning signs to watch for:

• Inconsistent tax filings: When a company reports conflicting residency statuses or beneficial ownership information across jurisdictions, it raises audit risks. These discrepancies often emerge during due diligence, revealing gaps in the target company’s compliance.
• Missing or incomplete documentation: Essential documents like residency certificates, ownership declarations, or corporate resolutions must be accurate and up-to-date. Without them, treaty benefit claims can be delayed or denied, derailing the deal timeline.
• Transfer pricing violations: If intercompany transactions lack proper documentation or don’t follow arm’s length principles, tax authorities may challenge the treaty structure. This is particularly problematic when the acquiring company depends on existing transfer pricing arrangements.
• Failure to meet substance requirements: Companies claiming treaty benefits without adequate local operations - such as no local employees or minimal assets - face heightened scrutiny. Tax authorities are increasingly targeting such setups.
• Timing mismatches: Claiming treaty benefits for an entire tax year when the qualifying structure was only in place for part of it, or overlooking ownership changes during a transaction, can create compliance vulnerabilities.

These red flags highlight areas where errors commonly occur, emphasizing the need for proactive measures to avoid treaty claim issues.

Prevent Treaty Benefit Claim Errors

Once potential risks are identified, the focus should shift to preventing errors in treaty benefit claims. Here’s how:

• Understand treaty language and limitations: Misinterpreting treaty provisions or overlooking limitation-on-benefits clauses can lead to costly mistakes. Treaties often include specific definitions and anti-treaty shopping rules that require careful analysis, especially in complex M&A structures.
• Secure proper certifications upfront: Tax authorities expect all necessary documentation, like residency certificates, to be in place before filing returns. Attempting to obtain certifications retroactively is rarely successful and can result in full withholding taxes, penalties, and interest.
• Account for domestic anti-avoidance rules: Even if a transaction qualifies under a treaty, domestic tax laws - such as controlled foreign corporation rules or general anti-avoidance doctrines - may impose additional obligations. Ignoring these can negate treaty benefits.
• Evaluate treaty shopping carefully: While some degree of treaty shopping is permissible, it requires a detailed review of substance requirements, business purpose tests, and international standards like those introduced by the OECD’s Base Erosion and Profit Shifting (BEPS) initiatives.

To minimize errors, establish clear documentation protocols early in the deal process. Create comprehensive checklists that cover all treaty requirements, assign responsibilities for securing documents, and allocate sufficient time for treaty analysis. Many companies now require treaty compliance sign-offs as a standard part of deal approval, treating these issues with the same importance as other critical conditions.

Use Technology and Expert Help to Reduce Risks

Leveraging the right tools and expertise can significantly lower the risk of treaty compliance issues:

• Specialized tax technology: Advanced systems can track deadlines, monitor regulatory changes across jurisdictions, and flag potential issues before they become major problems.
• Cross-border tax expertise: Local advisors bring invaluable insights into administrative practices, audit trends, and compliance approaches that aren’t always apparent in treaty texts. This is especially important for newer treaties with limited guidance.
• Regular compliance audits: Combining technology with expert reviews helps identify and address issues before tax authorities do. These audits should evaluate both current compliance and the ongoing validity of treaty positions, particularly during post-deal integration phases.

Phoenix Strategy Group offers comprehensive M&A support, blending advanced data analytics with deep international tax expertise. Their services help companies optimize treaty benefits while ensuring full compliance, a critical advantage for businesses pursuing cross-border growth.

Finally, invest in robust documentation systems post-deal to maintain compliance. These systems should handle multiple languages, various formats, and complex workflows across time zones. Doing so not only helps avoid penalties but also reduces the costs and stress of audit preparation.

Conclusion: Getting the Most from Tax Treaties in M&A

To make the most of tax treaties in cross-border M&A, it’s essential to weave treaty planning into every stage of the deal process. The complexity of international tax regulations, coupled with the high stakes of M&A, means treaty planning should be a core focus - not an afterthought.

By combining thorough due diligence with strategic deal structuring, companies can create transaction frameworks that reduce withholding taxes, align with long-term objectives, and unlock treaty benefits. This proactive approach not only enhances the financial outcome of the deal but also ensures a smoother path to achieving broader business goals.

Equally important is staying on top of compliance after the deal closes. Tax laws and treaties are constantly evolving due to legislative changes, court decisions, and regulatory updates. To keep pace, companies need robust documentation systems and regular compliance audits. This vigilance helps avoid penalties and disputes while ensuring treaty benefits are fully realized.

Technology and expert guidance play a key role here. Tools that monitor regulatory updates and identify potential risks can streamline compliance efforts. When paired with local tax expertise and cross-border advisory support, these resources minimize the chance of compliance missteps. As tax landscapes shift, these strategies help keep M&A transactions efficient and aligned with treaty benefits.

By following these strategic steps, companies - especially those in growth stages - can tap into expert M&A support, like the services offered by Phoenix Strategy Group. This ensures not only optimal use of tax treaties but also a disciplined approach to compliance.

Investing in early planning, structuring deals for tax efficiency, and maintaining rigorous compliance transforms tax treaties from complex legal documents into tools for gaining a competitive edge in cross-border transactions. With the right approach, these treaties can become a cornerstone for long-term success.
