More American professionals and entrepreneurs are looking beyond US borders. Whether driven by tax efficiency, lifestyle quality, access to EU markets, or simply a desire for change, the move to Europe — or its geographic neighbors — has never been more strategically attractive. But not all destinations are created equal.
Here is Helvetios’ curated breakdown of the top countries worth considering if you’re an American looking to relocate and launch or grow a business.
Top Countries to Start a Business in Europe from the USA
Estonia — The Digital Republic
Estonia has quietly built one of the most business-friendly ecosystems in the world. Its flagship e-Residency program allows anyone — including non-residents — to register and run an EU-based company entirely online. For Americans who want a foothold in the European market without committing to a full physical relocation, it’s a compelling entry point.
That said, full relocation comes with its own set of advantages. Estonia offers a flat income tax rate, a corporate tax system that only taxes distributed profits (meaning retained earnings grow tax-free), and a deeply digitized public administration — filing taxes, signing contracts, and accessing government services can all be done from a laptop.
Key advantages:
- EU membership with full market access
- Zero corporate tax on reinvested profits
- Fast and affordable company formation (under €300 with E-Residency Card)
- Strong startup and tech ecosystem, especially in Tallinn
- English widely spoken in business circles
Things to consider: Estonia’s small domestic market means most businesses will be internationally focused from day one. Winters are long. And while cost of living is low by Western European standards, Tallinn’s rapid growth has pushed up property prices.
Best for: Tech founders, digital entrepreneurs, remote workers seeking EU residency, and those wanting a lean, compliant EU corporate structure.
Portugal — The Lifestyle-Meets-Business Sweet Spot
Portugal has earned its reputation as one of the most welcoming countries for foreign professionals and entrepreneurs. The NHR (Non-Habitual Resident) tax regime — now evolving into the IFICI regime — has attracted thousands of international professionals by offering flat or reduced tax rates on certain foreign-sourced income for up to ten years.
Lisbon and Porto have emerged as genuine startup hubs with access to EU funding, a growing pool of English-speaking tech talent, and strong investor networks. The cost of living, while rising, remains lower than most Western European capitals.
Portugal’s Golden Visa program (now restructured) and D8 Digital Nomad Visa offer multiple pathways for Americans to establish legal residency. The country’s bureaucracy can be slow, but the overall reception toward foreign entrepreneurs is warm.
Key advantages:
- EU residency and passport pathway
- Favourable tax treatment for new residents
- High quality of life — climate, food, safety, healthcare
- Growing international professional community
- Strong flight connections to the US and rest of Europe
Things to consider: The NHR/IFICI regime changes require careful planning. Housing in Lisbon has become competitive. Portuguese bureaucracy can be slow without professional guidance.
Best for: Entrepreneurs, consultants, investors, and professionals in tech, finance, and creative industries seeking EU residency with an exceptional lifestyle.
United Arab Emirates — Zero Tax, Global Hub
While not in Europe, the UAE — and Dubai in particular — consistently tops relocation lists for ambitious American professionals. The reasons are straightforward: zero personal income tax, zero corporate tax on most activities (a 9% federal rate was introduced in 2023, with significant exemptions), and a world-class infrastructure designed to attract global talent and capital.
Free zones such as DIFC, ADGM, and Dubai Internet City allow 100% foreign ownership, full profit repatriation, and streamlined setup processes. The UAE’s location as a bridge between East and West, combined with strong US ties and English as the de facto business language, makes it accessible for Americans.
Key advantages:
- Zero personal income tax
- Low or zero corporate tax depending on structure and free zone
- Excellent international connectivity
- Strong banking and financial infrastructure
- Fast business setup — companies can be operational within days
Things to consider: The UAE is not in the EU, so it doesn’t provide European market access. Cultural adaptation is required. Long-term residency depends on maintaining economic activity. Heat and lifestyle differences may not suit everyone.
Best for: Finance professionals, trading companies, consultants, high earners looking to optimize tax exposure, and businesses with international — not specifically EU-focused — operations.
United Kingdom — Familiar, But Different
Post-Brexit Britain occupies a unique position. It’s no longer an EU member, which reduces its appeal for those specifically seeking European market access.
However, for Americans, the UK offers a number of distinct advantages: a shared language, a common-law legal system that mirrors the US in many respects, deep financial markets, and London’s status as one of the world’s top global business cities.
The Global Talent Visa and Innovator Founder Visa are among the most accessible routes for entrepreneurs. Corporation tax is 25% for larger companies (19% for smaller ones), which is competitive by G7 standards. The UK’s startup ecosystem — particularly in London, Manchester, and Edinburgh — remains world-class.
Key advantages:
- Shared language and legal familiarity for Americans
- World-class financial and legal infrastructure
- Strong VC and startup funding ecosystem
- No language barrier, simplified integration
- Time zone friendly for transatlantic business
Things to consider: No longer provides EU single market access. High cost of living in London. Immigration rules have tightened. Tax efficiency is moderate compared to UAE or Estonia.
Best for: Finance, legal, media, and tech professionals; entrepreneurs targeting UK or global (non-EU) markets; Americans who want a culturally familiar English-speaking base.
How to Choose the Right Destination
There’s no one-size-fits-all answer. The right country depends on your industry, tax situation, family circumstances, lifestyle priorities, and long-term goals. A tech founder optimizing for lean EU operations will prioritize Estonia. A consultant valuing lifestyle and EU residency may prefer Portugal. A high-earning finance professional minimizing tax exposure might choose Dubai. And an entrepreneur comfortable in an English-speaking common-law environment may find the UK the most natural fit.
What’s consistent across all four is this: the move requires professional planning. Visa applications, company formations, banking setups, tax treaty analysis, and local compliance are not DIY projects — especially when you’re navigating unfamiliar legal systems from across the Atlantic.

Q&A — Common Questions from Americans Considering the Move
Can I keep my US citizenship if I move to Europe or the UAE?
Yes. The US does not require you to renounce citizenship when obtaining foreign residency or even a second passport. However, US citizens remain subject to US tax obligations worldwide — a key reason professional tax advice is essential before any move.
Does moving abroad reduce my US tax burden?
Not automatically. The US taxes citizens on global income regardless of where they live. However, mechanisms like the Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credits (FTC) can significantly reduce double taxation. The structure of your business and residency matters enormously here.
How long does it take to set up a company in these countries?
Estonia is the fastest — an e-Residency company can be set up in days. The UAE’s free zones typically take 1–2 weeks. Portugal and the UK range from a few days (online) to a few weeks depending on the structure and required licenses.
Do I need to physically live in the country to benefit from its tax system?
It depends on the regime. Estonia’s e-Residency does not confer tax residency on its own. Portugal’s NHR/IFICI requires 183+ days per year. UAE residency is typically tied to maintaining a UAE-based economic activity and presence. Each situation is different — and the details matter.
Is it difficult to open a business bank account as a non-resident?
Banking can be one of the trickier steps, particularly in Europe where KYC (Know Your Customer) requirements are strict. It’s one of the areas where having a professional guide with existing banking relationships makes a material difference.
