International Tax

Global Tax Clarity for Businesses That Don’t Stand Still

The World Moves Quickly. Your Tax Strategy Should Keep Pace.

Global operations bring opportunity — and complexity. Regulation evolves. Markets shift. Supply chains adapt. And the tax rules that once felt manageable can suddenly feel murky.

As your business reaches across borders, so do your tax responsibilities. We help you make sense of what’s required, what’s changing, and what matters most — with steady guidance, practical insight, and a partner who stays close as you grow.

You may be navigating:

New entities or operations overseas
Partnerships or programs in unfamiliar jurisdictions
Transfer pricing that no longer reflects today’s margins
Data challenges across teams, countries, and systems
Growing expectations from regulators and stakeholders
Uncertainty around Pillar Two, GILTI, CAMT, or foreign reporting

Stop Managing Global Risk. Start Architecting Global Certainty.

You’re leading a growth-focused company, but the international tax landscape is more volatile than ever. Between the new Global Minimum Tax (BEPS Pillar Two), the looming 2026 U.S. tax sunset, and the continuous threat of tariffs, complexity is no longer a compliance issue—it’s an existential threat to your Effective Tax Rate (ETR) and supply chain integrity.

We believe that extraordinary complexity demands an integrated, accountable partnership. Our specialized “big, small firm” service model ensures our senior partners remain focused on high-stakes strategy, delivering the white-glove service that you expect.

Your challenge

The BEPS Time Bomb: Your ETR is at risk from the new 15% global minimum tax, requiring constant restructuring and modeling.

Transfer Pricing Volatility: Tariffs and supply chain shifts force constant, complex adjustments to transfer pricing policies.

Lack of Consistency: Fragmented advice from multiple firms creates compliance risk across different global jurisdictions.

Springline's Strategic Advantage

Global Certainty, Senior Focus: Dedicated tax practitioners proactively model your ETR exposure and structure your entities for compliance and maximum defense.

Integrated Transfer Pricing Resilience: We integrate Transfer Pricing, Valuation, and International Tax to ensure your policies are defensible and resilient to geopolitical shocks and supply chain changes.

Unifying National Network: A single, consistent partner for all U.S. international tax needs—from U.S. inbound structuring to Controlled Foreign Entity (CFE) compliance in Asia and Europe.

Cross-Border Planning That Meets You at Every Stage

Whether you’re expanding your reach, aligning your operations, or preparing for a major transition, we help you design structures that support how your business actually works, for today and tomorrow.

We organize our work around the points where global complexity shows up most often. Our advisory services are structured to provide you with a comprehensive, defensible framework for operations and capital.

Complexity at this scale requires decisive action and technical mastery. We manage the immediate and future threats to your global structure, giving you peace of mind and strategic leverage.

Pillar Two Readiness & ETR Modeling: Proactive modeling and scenario planning to anticipate the financial impact of the Global Minimum Tax, verifying your tax structure is compliant and optimized to withstand top-up taxes.
U.S. Tax Sunset Structuring: Strategic planning and restructuring to prepare for the looming changes to U.S. international provisions, including GILTI, FDII, and BEAT.
Controversy and Audit Defense: Dedicated senior support for managing international tax controversies and audits, providing expert technical analysis and robust defense documentation.
Controlled Foreign Entity (CFE) Compliance: Handling the complex, ongoing tax reporting required on the U.S. side for foreign operations in high-risk or specialized jurisdictions, such as China and the UK.

In a world defined by trade wars and supply chain disruption, Transfer Pricing (TP) is no longer just a compliance task, it’s a critical risk management function. We make sure your intercompany policies are not just compliant, but profitable and defensible.

Integrated TP for Resilience: We integrate tax strategy with valuation expertise to ensure that structural changes (such as nearshoring) result in defensible transfer pricing policies that reflect commercial and geopolitical realities.
Documentation & Audit Support: Creating robust, country-specific documentation that clearly defines the arm’s-length principle of your transactions, helping to provide the necessary audit defense when facing aggressive tax authorities.
IP & Valuation: Specialized analysis of intellectual property (IP) migration, valuation, and cost-sharing arrangements, designed to support the management of intangible assets in alignment with tax efficiency and regulatory expectations.

Transfer Pricing isn’t only about documentation. It’s about aligning your economics with your operations in a way that holds up under scrutiny.

We help you:

Build or refresh policies
Address supply chain changes
Adjust for shifting margins
Produce defensible analyses
Prepare for reviews or disputes

Is Your International Tax Plan Cleared for Takeoff?

Before moving forward on your global journey, it helps to take a quick look at where you stand today. Consider the following prompts a short pre-flight check: a moment of reflection can highlight areas that deserve closer attention before you continue expanding or refining your operations abroad.

Our transfer pricing reflects last year, not this year.
We’re unsure what Pillar Two — or its local equivalents — means for us.
We’ve expanded abroad faster than our tax planning.
We rely on several teams for data, and timing is a challenge.
We don’t have a clear, confident narrative about our effective tax rate.
Our global structure has evolved, but we haven’t revisited our tax approach.

If this checkpoint surfaced areas that could use attention, we’d be glad to help you make sense of them. A brief conversation can quickly clarify what matters now, what can wait, and how to move ahead with confidence.

We believe strong work starts with strong relationships. Soon, you’ll see more of the people leading and shaping this practice.
