Lost in Familiar Territory: Why UK Businesses Struggle in the US Despite Speaking the Language
Of all the foreign businesses that expand to the United States, UK companies are among the most likely to be underprepared, not because they lack sophistication, but because they feel too comfortable.
Shared language creates an illusion of shared context. A British founder reads the same contracts, watches the same financial news, and speaks fluently with American counterparts. The cultural friction that trips up a German or Japanese company entering the US seems absent. So UK businesses often skip the homework that their continental European counterparts do as a matter of course.
That's the trap. The US and the UK share a language, not a rulebook. And the gaps between them in tax, employment, compliance, and business culture, are deep enough to derail an expansion that looked straight forward on paper.
The False Familiarity Problem
Before getting into specifics, it's worth naming the pattern directly: UK businesses entering the US tend to underestimate the differences because the surface-level experience feels familiar.
The contracts are in English. The business etiquette seems close enough. American counterparts are friendly and direct. The legal documents look similar to what you'd see at home. So assumptions get made about how employment works, how taxes operate, how customers expect to be treated, how disputes get resolved. Those assumptions simply don't hold up.
The companies that navigate the US expansion most successfully are often not the ones with the most resources, but the ones who resist the assumption that familiarity equals equivalence. They ask the questions a German company would ask, even when the answers seem obvious.
The Tax System Is Not a Simpler Version of HMRC
UK businesses are accustomed to a centralized tax authority, HMRC. And a relatively unified national tax framework. VAT is collected at 20% across most goods and services. Corporation tax has a clear rate. The rules are complex, but they operate from one rulebook.
The US has no equivalent structure.
Federal tax is just the starting point. Every state levies its own income or franchise tax, with different rates, different filing requirements, and different definitions of what constitutes taxable activity. Some states (Texas, Washington, Nevada) have no corporate income tax at all. Others (California, New York) are among the most aggressive tax regimes in the developed world.
Sales tax is where UK businesses consistently get caught out. There is no federal VAT in the US. Instead, there are over 10,000 separate sales tax jurisdictions, state, county, city, and special district. Each with different rates and different definitions of what's taxable. A product that's exempt in one state may be taxable in the next. Following a 2018 Supreme Court ruling, states can assert tax obligations based on economic activity alone, meaning a UK business selling online into the US can trigger sales tax obligations in dozens of states without ever setting foot on American soil.
The UK-US tax treaty exists and does provide meaningful benefits. Reduced withholding rates on dividends, interest, and royalties between UK and US entities, and protections against double taxation. But claiming those benefits requires proper structuring. A UK company that sets up a US entity without advice on treaty positions may pay full withholding rates unnecessarily, or worse, lose treaty protection entirely through poor structuring choices.
Employment Law Is Almost the Opposite of What You're Used To
This is where the UK-US gap is starkest, and where the shared language does the most damage, because the terminology sounds the same while meaning something completely different.
At-will employment: In the UK, employees have substantial statutory protections from the moment of employment, with unfair dismissal rights typically kicking in after two years. In the US, most states operate under at-will employment, meaning either party can end the employment relationship at any time, for any reason, with no notice required (unless a contract specifies otherwise). UK businesses often find this jarring, and sometimes overcorrect by offering UK-style contractual protections that limit their flexibility unnecessarily.
Benefits expectations: In the UK, healthcare is not an employer obligation, the NHS provides a baseline. In the US, employer-provided health insurance is the norm and, in many roles and markets, a basic expectation. A UK company hiring in New York or San Francisco without a competitive benefits package will lose candidates to domestic employers before salary is even discussed. Health insurance, dental, vision, 401(k) matching, and paid time off all need to be structured from day one.
Paid leave: The US has no federal statutory minimum paid leave requirement, this surprises almost every UK employer. Paid holiday is entirely at the employer's discretion (except where individual states mandate it). This doesn't mean you should offer nothing, competitive hiring requires it, but it means the baseline assumptions that govern UK employment don't apply.
Payroll complexity: UK payroll runs through PAYE, a relatively centralized system. US payroll involves federal withholding, state withholding (in each state where you have employees), local taxes in some cities, Social Security, Medicare, federal unemployment (FUTA), and state unemployment insurance (SUI), each with its own filing calendar and deposit requirements. A UK business with employees in three US states is effectively managing three separate payroll compliance programs simultaneously.
Corporate Structure Decisions Don't Map Cleanly
A UK Limited Company is not the same as a US LLC or a US C-Corporation, and the decision about which US entity to form doesn't have a clean UK analogue.
UK businesses often assume the LLC is "like a Ltd", both have limited liability and relatively simple compliance. In terms of liability protection, that's broadly true. But the tax treatment is fundamentally different. A US LLC is a pass-through entity by default, profits flow through to the owners and are taxed at their individual rates. For a UK parent company owning a US LLC, this means the UK company is taxed in the US on its share of the LLC's profits, potentially creating mismatches with UK accounting treatment and triggering complex cross-border tax issues.
A C-Corporation is often the cleaner choice for UK parents, it creates a clear taxable entity in the US, and the UK-US treaty governs the treatment of dividends paid upstream. But C-Corps face double taxation (corporate tax at 21%, then withholding on dividends), which needs to be modelled carefully.
The entity decision should be made jointly by a US CPA and a UK tax adviser who can assess the treatment on both sides of the Atlantic simultaneously.
Business Culture: Same Words, Different Meanings
Beyond the regulatory differences, UK businesses often misjudge the cultural dynamics of the American market in ways that affect sales, hiring, and partnerships.
Americans are not reserved about price: UK business culture tends toward indirectness, pricing discussions can be circuitous, and appearing too eager is seen as a weakness. US business culture is more direct. Customers expect clear pricing, fast responses, and decisive proposals. British understatement, the tendency to describe a strong product as "fairly good" or "not bad" reads as lack of confidence in the US market, not modesty.
Litigation awareness: The US is significantly more litigious than the UK. Contracts need to be more detailed, liability clauses matter more, and indemnification provisions that would seem excessive in a UK context are standard in US commercial agreements. UK businesses that enter the US with UK-style contracts, or worse, without clear written contracts, create legal exposure they wouldn't face athome.
Relationship building happens at different speeds: US business culture can appear extremely warm and accessible upfront, first names, open doors, enthusiasm. UK businesses sometimes mistake this for closeness that hasn't yet been earned. American business relationships tend to be more transactional early and trust-based later; the warmth at the outset doesn't necessarily signal commitment.
Spelling and terminology: This is a small point but a real one for marketing and client-facing materials. "Colour", "programme", "authorised", "whilst", these aren't wrong, but they signal foreignness to an American audience. In B2C contexts especially, localization of written materials matters. So does terminology: "holiday" for time off, "CV" instead of resume, "solicitor" instead of attorney, these create subtle friction that accumulates.
What UK Businesses Should Do Differently
The adjustments aren't about starting from scratch, UK businesses bring real advantages to the US market, including credibility, often a strong existing client base, and operational maturity. The goal is to apply those advantages without the blind spots that shared language can create.
Practically, that means:
Treat the US as a foreign market, because it is. Do the due diligence on tax, employment, and compliance that you would if you were expanding to Germany or Japan. The fact that you can read the regulations without a translator doesn't mean you understand them in context.
Get both UK and US professional advice simultaneously. Cross-border structuring decisions made by a US adviser without UK input, or vice versa, routinely create problems on the other side. The UK-US tax treaty, transfer pricing, and entity structure all require a view from both ends.
Budget for benefits from day one. You will not hire competitive US talent on a UK-style compensation package. Health insurance, 401(k) matching, and paid leave are not optional extras — they're baseline expectations in the US employment market.
Localize your customer-facing materials. Not just spelling, tone, references, value propositions, and case studies. What resonates with a UK buyer doesn't always translate directly to a US audience, even in the same language.
The Opportunity Is Real, So Is the Risk
The US is the world's largest consumer market, and the UK's shared language, legal heritage, and business culture genuinely do provide advantages over competitors entering from further afield. The market is accessible in away that few other foreign markets are.
But accessible is not the same as easy. The businesses that succeed in the US are the ones that respect the differences, not the ones that assume familiarity makes preparation unnecessary.
