US LLC vs. UK Limited: Choosing the Best Entity for Non-US Service Businesses in 2026

Setting up a US LLC as a non-resident typically costs between $300 and $900, depending on the state and services you include. This usually covers state filing fees, registered agent services for the first year, and basic formation assistance. States like Wyoming have lower filing fees, around $100-$150, while Delaware can be slightly higher.

A UK Limited company can be registered for a much lower upfront cost, often between £12 and £50 (approximately $15-$65). This fee usually covers the Companies House registration. However, many founders opt for a formation agent, which can add another £50 to £150 ($65-$190) for a total of around $100-$300 for a professionally managed setup. Both options generally offer quick formation, often within a few business days.

US LLCs require annual state fees, which vary widely. Wyoming charges $60 per year, while Delaware charges a Franchise Tax of $300 per year. All US LLCs must also maintain a registered agent, costing $100-$150 annually. Crucially, as of 2024, US LLCs must comply with Beneficial Ownership Information (BOI) reporting to FinCEN, which requires updating beneficial owner details if they change. This adds a new layer of ongoing compliance.

UK Limited companies have simpler annual compliance. They must file an annual confirmation statement with Companies House, costing £13 (around $16) if filed online. They also need to file annual accounts with Companies House and HMRC, which typically requires an accountant. Professional accounting services for a UK Ltd can range from £500 to £2000 ($650-$2600) annually, depending on activity volume. There is no equivalent of the US BOI reporting for UK companies.

A US LLC, when owned by a single non-US resident, is typically treated as a disregarded entity for US tax purposes. This means the LLC itself does not pay US federal income tax. The owner is only subject to US tax if the LLC is considered engaged in a US trade or business (USTB) and generates effectively connected income (ECI). For service businesses operating entirely outside the US, with no US physical presence or employees, the US LLC might be considered non-USTB, resulting in no US income tax. However, informational returns like Form 5472 and Form 1120 (for informational purposes only) are mandatory, with hefty penalties for non-filing.

A UK Limited company is subject to UK corporation tax on its profits. The main rate of corporation tax is currently 25% for profits over £250,000, with a small profits rate of 19% for profits up to £50,000. Profits between £50,000 and £250,000 are taxed at 25% with marginal relief. This is a direct tax on the company's profits before any distributions to shareholders. Dividends paid to non-UK resident shareholders are generally not subject to further UK withholding tax, though the shareholder's home country tax rules apply.

Opening a traditional US bank account for a non-resident owned US LLC can be challenging. Many major banks require an in-person visit. Challenger banks like Mercury and Wise are popular choices that allow remote account opening for US LLCs, offering USD accounts, virtual cards, and international payment capabilities. Stripe and PayPal are readily available payment processors for US LLCs, providing broad compatibility for online services.

UK Limited companies generally have better access to traditional banking options, even for non-residents. Many UK high street banks (like Barclays, HSBC, Lloyds) may still require a UK director or an in-person visit, but challenger banks like Revolut Business, Wise Business, and Starling Bank offer online account opening for non-resident directors. This often simplifies managing multi-currency operations and receiving payments from EU and UK clients. Payment processors like Stripe, PayPal, and Square also integrate well with UK bank accounts.

A US LLC carries significant prestige globally, especially in tech and e-commerce sectors. It signals professionalism and trustworthiness to clients and partners in North America and beyond. Many global platforms and service providers prioritize US-based entities, often leading to smoother onboarding and access to US-specific tools and integrations. This can be a strong advantage when targeting US clients or seeking US-based funding.

A UK Limited company also offers excellent international credibility, particularly within Europe and Commonwealth countries. The UK's strong legal framework and business-friendly environment are well-regarded. For service businesses primarily targeting European clients, a UK Ltd might offer a perceived advantage and simpler compliance with regional regulations, such as GDPR. Both entities are globally recognized and generally well-received.

The primary trade-off for a US LLC is the potential for zero US corporate income tax versus the complexity of banking and navigating US tax reporting requirements (even for non-taxable entities). The new BOI reporting also adds a permanent compliance task. However, for those serving US customers or needing a strong US brand identity, an LLC is often the best choice. Bastion Formations can assist with navigating these complexities.

For a UK Limited company, the main trade-off is paying UK corporation tax on profits, which might be higher than zero. However, it offers generally easier banking access, simpler annual reporting (no BOI equivalent), and strong credibility in the European market. If your primary market is Europe or you prefer clearer corporate tax rules, a UK Ltd might be more straightforward.
