US LLC vs. UK Ltd: Tax & Banking for Canadian Founders in 2026

For Canadian founders, a US LLC typically offers pass-through taxation as a disregarded entity or partnership. This means the LLC itself does not pay US corporate income tax on foreign-sourced income. Instead, profits flow directly to the Canadian owner's personal tax return.

You will generally owe US tax only if your LLC has US-sourced income, such as from US customers or operations within the United States. Even then, you might only pay a 30% flat tax on gross US-sourced income or elect to be treated as engaged in a US trade or business. Canadians also benefit from the US-Canada income tax treaty, which can reduce or eliminate certain US tax liabilities. Always consult with a tax professional specializing in international taxation.

A UK Ltd company is a separate legal entity and is subject to UK corporate tax on its global profits. The current UK corporation tax rate is 19% for profits up to £50,000 and 25% for profits over £250,000, with a tapering rate in between. Canadian founders will need to account for this tax at the company level.

Distributing profits from a UK Ltd to a Canadian owner typically involves dividends or salaries. Dividends are generally tax-free at the company level but taxable in Canada for the recipient. Salaries are subject to UK PAYE (Pay As You Earn) tax and National Insurance contributions, then also declared in Canada. This can lead to double taxation if not properly managed under the Canada-UK tax treaty.

Opening a US business bank account for an LLC as a Canadian non-resident requires an Employer Identification Number (EIN). You can obtain an EIN even without a US Social Security Number or ITIN. Many fintech banks, like Mercury, Stripe Atlas, or Wise Business, provide remote account opening options for non-resident-owned LLCs.

Traditional banks often require an in-person visit. Expect Know Your Customer (KYC) procedures. Having a clear business plan and understanding your entity structure will streamline the process. The process can take anywhere from a few days to several weeks, depending on the bank and your preparedness.

For a UK Ltd company, opening a UK business bank account is typically straightforward. Traditional UK banks like Barclays, HSBC, or NatWest offer business accounts. Fintech alternatives like Wise Business or Revolut Business also cater to non-resident directors.

While usually simpler than US banking for non-residents, some UK banks may still require directors to physically visit a branch. However, many fintech providers allow fully remote setup. You will need proof of identity, proof of address (Canadian address is usually acceptable), and company registration documents.

US LLCs must comply with state-specific annual reporting requirements, which vary in cost and frequency. All US LLCs must also comply with the Beneficial Ownership Information (BOI) reporting rule with FinCEN starting in 2024. This requires reporting identifying information about beneficial owners and company applicants.

Additionally, Canadian owners of US LLCs need to be aware of FATCA (Foreign Account Tax Compliance Act) and FBAR (Report of Foreign Bank and Financial Accounts) obligations. If your Canadian financial accounts exceed certain thresholds, you might need to report them to the IRS. This ensures transparency for the US tax authorities.

UK Ltd companies face several ongoing compliance obligations. This includes filing annual accounts with Companies House and HMRC, and an annual confirmation statement. Corporate tax returns must also be submitted to HMRC.

Canadian owners of UK Ltd companies will also be subject to the Common Reporting Standard (CRS). UK financial institutions report account information to HMRC, who then exchange this data with Canadian tax authorities under international agreements. This ensures transparency regarding your financial holdings.

The initial cost to form a US LLC typically ranges from $50 to $500, depending on the state and registered agent fees. Annual registered agent fees are usually $100-$150. State annual reports or franchise taxes can range from $0 (Wyoming) to $300 (California, though less common for non-residents). Professional EIN application services average $100-$250. Expect $500-$1,500 annually for tax and compliance support.

Forming a UK Ltd costs around £12-£50 (approximately $15-$65 USD) directly with Companies House. Registered office services cost £30-£100 annually (around $40-$130 USD). Annual accounting and tax compliance for a UK Ltd generally cost £500-£1,500 (approximately $650-$1,950 USD). These figures are estimates and can vary based on service providers and company activity.
