VANCOUVER, British Columbia – U.S. entrepreneurs are increasingly turning to second passports to expand mobility, secure investment opportunities, and shield themselves from political or economic uncertainty. Yet as more business founders embrace global citizenship, many are discovering that the complexities of U.S. tax law, particularly controlled foreign corporation rules and the global intangible low-taxed income regime, follow them wherever they go. The result is a rising wave of tax surprises that have left some entrepreneurs scrambling to restructure their companies after the fact, while others have faced costly audits and penalties.
The story of second passports has often been told through the lens of lifestyle, access, and freedom of movement. What is less visible, but far more consequential for entrepreneurs, is the tax overlay that remains firmly tied to U.S. citizens, regardless of the number of citizenships they hold. At the center of this issue are two acronyms that dictate the fate of many global business structures: CFC and GILTI.
Controlled foreign corporation rules, which apply when U.S. persons own more than 50 percent of a foreign company, and global intangible low-taxed income provisions, introduced in the 2017 Tax Cuts and Jobs Act, are designed to prevent Americans from shifting profits offshore. For U.S. citizens who take up new citizenship abroad but maintain their American passport, these rules are not optional. They are binding, complex, and often misunderstood.
This press release examines how the second passport trend intersects with U.S. tax regimes, why many entrepreneurs underestimate their exposure to these risks, and what strategies can help mitigate financial and legal risks. It draws on case studies from technology, finance, and emerging industries to illustrate how business founders navigate the global tax landscape and why missteps can be devastating.
The allure of a second passport has never been more potent. According to data from Caribbean and European citizenship-by-investment programs, applications by U.S. nationals have surged by double digits since 2020. Political polarization, pandemic travel restrictions, and concerns over future tax increases have motivated many to diversify their citizenship portfolios. For entrepreneurs, the attraction is clear: a second passport can ease cross-border business travel, unlock residence rights in major markets, and serve as a hedge against domestic policy shifts. However, this growing mobility has collided with the immovable principle of U.S. worldwide taxation. Unlike most countries, the United States taxes its citizens on their worldwide income, regardless of their place of residence. The only exit is formal expatriation, a step that carries its own tax consequences and emotional complexities.
The controlled foreign corporation regime was initially enacted in the 1960s to prevent U.S. taxpayers from parking income in low-tax jurisdictions. It attributes specific categories of passive and easily movable income, such as dividends, interest, royalties, and certain types of service income, directly to the U.S. shareholder, even if the foreign company never distributes any cash.
GILTI, enacted more recently, broadened the net by targeting active income from intangible assets, such as intellectual property, held in foreign subsidiaries. For technology entrepreneurs, who often operate global structures with valuable IP, GILTI can apply even if operations are legitimate and profits remain reinvested abroad.
A case study helps illustrate this. Consider a U.S. software founder who acquires Maltese citizenship through investment and relocates to Valletta. She believes her new passport, combined with Malta’s favorable corporate tax refunds, will reduce her tax burden. She incorporates a Maltese holding company to own her intellectual property and begins licensing software globally. What she does not anticipate is that, as a U.S. citizen, her Maltese entity qualifies as a controlled foreign corporation under U.S. tax law.
The licensing income, which is deemed intangible and highly mobile, falls squarely within the GILTI regime. Instead of reaping low Maltese taxes, she finds herself with additional U.S. tax reporting, potential double taxation, and the administrative burden of foreign tax credit planning. Her second passport may help her live and work in Europe, but it does not shield her from American tax rules.
Contrast this with another case. A U.S. entrepreneur in the renewable energy sector obtains Portuguese citizenship through residency and later naturalization. He carefully structures his overseas operations, placing capital-intensive manufacturing assets in his Portuguese company and documenting active business functions locally.
Because GILTI allows for an exclusion tied to tangible assets, the so-called qualified business asset investment, the Portuguese operations generate less residual income subject to GILTI. By aligning substance with structure and ensuring that employees, assets, and decision-making occur in Portugal, he reduces the risk of phantom income taxation in the U.S. This case highlights that while second passports do not eliminate U.S. tax liability, thoughtful planning can mitigate the associated friction.
The misconception that a second passport alone exempts one from U.S. tax obligations is widespread. Marketing materials for citizenship-by-investment programs often highlight the tax advantages of their jurisdictions without acknowledging that Americans remain taxable. In practice, a U.S. entrepreneur who becomes a citizen of St. Kitts or Dominica, or who secures an EU passport through golden visa programs, continues to file annual U.S. returns unless they formally expatriate. The Internal Revenue Service has reinforced this point through enforcement actions, reminding dual citizens that noncompliance can lead to severe penalties.
Entrepreneurs often compare their situations to those of peers from other countries. In the United Kingdom, for example, the remittance basis allows non-domiciled residents to shield foreign income from U.K. taxation until it is brought into the country. Portugal’s non-habitual resident program offers a decade of favorable treatment for foreign-sourced income.
The United Arab Emirates offers a territorial tax system with a zero percent tax rate on most foreign income. Singapore similarly exempts foreign-sourced income not remitted locally. For U.S. citizens, however, these advantages are tempered by American rules. Even if a U.S. entrepreneur qualifies for NHR in Portugal, the IRS will still require reporting and potential taxation, often offset only by foreign tax credits.
The global tax landscape is also undergoing significant changes. The OECD’s Pillar Two initiative, which seeks to implement a global minimum tax of 15 percent on multinational enterprises, further complicates planning. U.S. entrepreneurs with international structures must consider not only American rules but also the compliance obligations of host jurisdictions implementing minimum tax standards. The interplay of GILTI and Pillar Two remains a subject of intense debate, but the risk of overlapping obligations is real.
Another case study highlights the enforcement angle. A U.S. entrepreneur in the blockchain sector obtained citizenship in Cyprus, believing that the island’s favorable tax regime and EU membership would provide protection. He structured token sales through a Cypriot company and reported only local obligations.
U.S. authorities, leveraging FATCA and information-sharing agreements, uncovered the arrangement. The IRS argued that his company was a controlled foreign corporation and that token revenues fell under GILTI. After a lengthy audit, he faced back taxes, penalties, and interest, as well as reputational damage. This case illustrates how digital assets, often marketed as borderless, remain subject to nationality-based taxation.
The IRS has invested heavily in global enforcement. Through FATCA, more than 100 countries report financial account information of U.S. citizens and residents. Whistleblower programs have incentivized insiders to disclose aggressive structures. High-profile prosecutions have highlighted the risks associated with hiding behind second passports. For entrepreneurs, the lesson is that transparency and proactive planning are essential.
Building structures without tax surprises requires a holistic approach. The first step is acknowledging that citizenship, not residence alone, drives taxation in the U.S. A second passport can offer mobility benefits but does not alter this reality unless paired with a formal expatriation process. Even expatriation has complexities, including potential exit taxes on unrealized gains and ongoing tax exposure for certain U.S.-source income.
Within this framework, entrepreneurs should design foreign corporations with substance. Locating real operations, employees, and decision-making in the jurisdiction of incorporation strengthens the argument that income is active, not passive. Leveraging qualified business asset investment rules can reduce GILTI exposure.
Coordinating tax treaties can help mitigate double taxation. Most importantly, maintaining rigorous compliance with accurate filings of Form 5471, GILTI calculations, and foreign bank account reports demonstrates good faith and reduces the risk of punitive penalties.
Some entrepreneurs explore hybrid structures, using partnerships, trusts, or disregarded entities to align income recognition with personal tax positions. Others pursue timing strategies, deferring income or aligning distributions with high foreign tax years to maximize credits. Each strategy carries risks, and no two cases are identical. Case studies show that those who succeed are those who approach the issue early, with expert guidance, rather than reacting after the IRS intervenes.
A compelling example comes from an American entrepreneur in the healthcare technology field who obtained citizenship in Singapore. By carefully documenting research, development, and executive decision-making in Singapore, and by reinvesting profits into tangible assets, he minimized his residual income subject to GILTI. At the same time, he filed all U.S. forms and claimed foreign tax credits. His approach, though not tax-free, provided predictability and avoided enforcement actions.
By contrast, another case involved a U.S. citizen who obtained citizenship in Grenada and attempted to operate through a Belizean company with no staff, assets, or local functions. The IRS deemed the company a shell, attributed all income back to the shareholder, and imposed penalties for unfiled CFC disclosures. His second passport did nothing to protect him, and the lack of substance in his structure proved fatal.
As second passports grow more popular among U.S. entrepreneurs, the intersection with CFC and GILTI rules will remain a critical topic. Policymakers continue to debate reforms, and entrepreneurs continue to adapt. What is clear is that mobility and opportunity cannot be separated from compliance and transparency. For every success story of seamless global structuring, there are cautionary tales of miscalculation.
Entrepreneurs should view second passports as tools for opportunity, not tax escape hatches. They should invest in education, seek counsel familiar with both U.S. and foreign systems, and anticipate evolving standards such as global minimum tax rules. Above all, they should approach global structuring with the same rigor they apply to product design or capital raising.
The rise of second passports is a defining feature of today’s entrepreneurial landscape. It reflects ambition, resilience, and adaptability. But without careful attention to CFC and GILTI rules, it can also lead to costly mistakes. The entrepreneurs who succeed in this environment are those who integrate tax planning into their global vision, ensuring that their structures are built for sustainability, not just speed.
As the global economy continues to evolve, second passports will remain part of the toolkit for entrepreneurs. But they must be wielded with full awareness of the obligations that come with U.S. citizenship.
The opportunity is real, but so are the risks. Navigating this terrain requires diligence, foresight, and an unwavering commitment to compliance.
