Best US Business Banking for UK Founders Running US LLCs
HMRC International Manual paragraph INTM180030 treats single-member US LLCs as transparent for UK tax purposes — matching the IRS disregarded-entity classification and sidestepping the 50–75% effective-rate trap the CRA produces for Canadian residents holding the same structure.
US business bank accounts for non-US-resident founders sit on a tightening regulatory shelf. Acceptance rates, KYC document requirements, and supported jurisdictions shift quarterly. The current 2026 Q2 state for the three vendor-neutral options that GS tracks is below, alongside the country-specific FEMA / SAFE / SBP / OFAC layer that defines what a founder from this country can actually use.

UK residents opening US LLC bank accounts operate in one of the lowest-friction non-US jurisdictions in this matrix. The UK has had no individual outbound foreign-exchange controls since the 1979 abolition under the Exchange Control Act 1947; sterling moves freely to USD without quota interaction. The Financial Conduct Authority (FCA) regulates UK-domestic banking and does not gate US bank account access for UK residents. HMRC reporting flows through Self Assessment: the main return (SA100) plus the foreign-income supplement (SA106) when LLC distributions or attributed profits cross the reporting threshold.
The structural picture for UK residents holding US LLCs sits on top of the Anson v HMRC [2015] UKSC 44 Supreme Court decision. Historically HMRC treated US LLCs as opaque (corporate-like) entities, which produced a classification mismatch similar to the Canadian trap. Anson reversed the default in fact-specific situations: the Supreme Court held that a Delaware LLC could be transparent for UK tax purposes where the operating agreement vested profits directly in members rather than distributing through a corporate-style declared dividend. HMRC's post-Anson guidance (International Manual INTM180030 and the INTM334000 series) accepts transparent treatment on a case-by-case basis when the LLC operating agreement supports it; opaque treatment remains the default in less clearly-drafted situations. The US-UK Income Tax Treaty (1975, last amended by 2002 Protocol) covers cross-border business profits (Article 7), residence tie-breakers (Article 4), and dividend / interest withholding rates.
UK residents working as solo founders through US LLCs face two additional UK-specific considerations beyond banking access. IR35 / off-payroll-working rules (ITEPA 2003 Chapter 10) apply when a UK-resident contractor invoices a UK end-client through a US LLC structure — the LLC does not insulate the founder from inside-IR35 reclassification by HMRC. Worldwide Disclosure Facility and Requirement to Correct rules also continue to apply to undeclared foreign income.
2026 Q2 banking access for UK-passport applicants matches the Canadian baseline. Mercury (via Choice Financial Group and Column N.A., Members FDIC) and Relay (via Thread Bank, Member FDIC) accept UK residents with 3–7 business day review windows. Wise Business is UK-headquartered (London FCA-regulated as Wise Payments Limited) and operates as the most native USD-receiving channel for UK founders.
