Cross-Border Tax Intelligence: Carol Larson’s Strategic Framework for Multijurisdictional Families

A proprietary methodology for structuring global wealth with precision, foresight, and jurisdictional fluency.

In the increasingly complex arena of global wealth, the families who thrive are the ones who anticipate—not react to—regulatory shifts, cross-border tax exposure, and the intricate consequences of mobility. Nowhere is this more evident than among multijurisdictional families whose financial, personal, and business lives span the United States, the European Union, the United Arab Emirates, and Latin America.

It is within this environment that Carol Larson, founder of Larson Wealth & Legacy, has developed one of the most respected strategic frameworks for global tax intelligence. Her methodology is not simply a set of guidelines or a procedural checklist. It is an integrated system, informed by decades of cross-border advisory work, designed to reconcile the competing demands of tax efficiency, regulatory compliance, personal mobility, and long-term family governance.

What follows is a detailed examination of this framework—how it works, why it matters, and what distinguishes it from the traditional models often applied by advisors operating within a single jurisdiction.

1. The Limitations of Traditional Single-Jurisdiction Analysis

Most tax systems were designed for individuals with static lives—citizens living, investing, and operating businesses within a single country. High-net-worth families today exist in an entirely different paradigm:

  • children attending school in Europe,

  • operating companies in the United States,

  • holding structures in the UAE,

  • real estate across multiple continents, and

  • heirs with mixed tax residencies.

Conventional tax analysis struggles under this weight. The result—frequent exposure to double taxation, ineffective succession plans, or unintended reporting obligations.

Carol Larson’s system begins where traditional advisory methods fail: with the recognition that multijurisdictional families require a unified and predictive strategy.

2. The Larson Multijurisdictional Matrix™

At the heart of Carol Larson’s approach is a proprietary diagnostic known internally as the Larson Multijurisdictional Matrix™.
It maps a family’s global footprint through five core dimensions:

  1. Tax Residency Profiles

  2. Asset Classification and Location

  3. Corporate and Holding Structures

  4. Mobility and Immigration Pathways

  5. Succession and Intergenerational Planning

Each dimension is reviewed independently and then cross-referenced against the others, identifying areas where jurisdictions interact—sometimes cooperatively, often contentiously.

This matrix is the reason Larson Wealth & Legacy is able to forecast exposure long before it materializes.

3. The Three Pillars of Cross-Border Tax Intelligence

Carol Larson’s methodology does not treat tax as an isolated discipline. Instead, it is built upon three interdependent pillars that together inform every strategic recommendation.

A. Predictive Tax Engineering

Rather than analyzing only current obligations, this component models:

  • anticipated residency changes,

  • currency risk,

  • upcoming regulatory reforms,

  • timing of liquidity events,

  • cross-border inheritance exposure, and

  • multi-jurisdictional reporting requirements.

The objective is simple:
to allow families to act before consequences arise.

B. Structural Integrity Across Borders

Families often inherit disconnected structures built in different eras, by different advisors, for different objectives. Carol Larson’s framework addresses the structural fragmentation head-on.

This includes:

  • reorganizing holding companies under a unified logic,

  • evaluating trusts and foundations for cross-border compatibility,

  • migrating entities when beneficial and permissible,

  • aligning corporate domiciles with tax-efficient jurisdictions.

The goal is a structure that is not only efficient, but durable—one that survives regulatory change.

C. Human-Centric Governance

A tax plan that ignores people ultimately collapses.
For this reason, the framework incorporates:

  • the family’s generational dynamics,

  • educational levels of heirs,

  • cultural expectations,

  • marital regimes,

  • comfort levels with risk and transparency.

This is where Carol Larson’s background in family governance becomes central. She understands that a global structure is only as strong as the people responsible for stewarding it.

4. Handling the Most Challenging Cross-Border Conflicts

Among the cases in which this framework proves indispensable are those involving:

  • U.S. citizens living abroad, who remain subject to worldwide taxation.

  • Brazilian residents newly exposed to offshore taxation under the 2024 Brazilian reform.

  • European citizens inheriting assets in the United States or UAE.

  • Families relocating to Dubai, seeking zero taxation but overlooking exit-tax rules or controlled foreign corporation exposure.

  • Entrepreneurs with dual corporate footprints, often subject to competing reporting standards.

Where most advisors attempt reactive repairs after the conflict emerges, Larson’s methodology anticipates these issues through multi-scenario modelling.

5. A Framework Rooted in Precision, Not Assumptions

Perhaps the most distinguishing feature of Carol Larson’s method is that it avoids the assumption that one jurisdiction’s logic applies elsewhere.

For example:

  • U.S. estate tax does not follow the same valuation logic used in the EU.

  • Brazil’s new offshore rules differ substantially from the U.S. GILTI or CFC models.

  • The UAE’s tax landscape, though favorable, demands structured governance to be sustainable.

This insistence on precision is where the methodology becomes most valuable for families with assets spanning four or more countries.

6. The Strategic Advantages for Multijurisdictional Families

Families using this system benefit from:

  • Reduced exposure to global double taxation

  • Streamlined structures that are easier to administer

  • Predictive succession mapping

  • Compliance alignment across conflicting jurisdictions

  • Clearer family governance protocols

  • Risk mitigation before mobility decisions

  • Transparent reporting frameworks that reduce regulatory friction

Most importantly, they benefit from the ability to make decisions anchored in legal certainty.

7. Why Carol Larson’s Framework Has Become a Global Benchmark

The success of this methodology is largely the result of Carol Larson’s unique professional trajectory. Her experience spans:

  • U.S. tax advisory,

  • Latin American regulatory reform,

  • European succession law,

  • international mobility strategy, and

  • UAE corporate and wealth structuring.

Few advisors combine these areas in a single practice. Fewer still have built a methodology that operates across all of them.

This is why families across continents increasingly rely on Larson Wealth & Legacy not only as advisors, but as architects of global continuity.

CONCLUSION

Cross-border tax intelligence is no longer optional.


For multijurisdictional families, it is the foundation upon which all other strategic, financial, and personal decisions must rest.

Carol Larson’s framework stands out because it recognizes the reality of the modern wealthy family: global, mobile, diversified, and exposed to regulatory environments that rarely speak to one another.

Her methodology provides a coherent language—one that aligns jurisdictions, structures, and generations into a unified strategy capable of sustaining wealth far beyond the present.

It is this disciplined, predictive, and human-centered approach that has positioned Larson Wealth & Legacy as a global leader in multi-jurisdictional advisory.
