US LLCs for Non-Residents: Maximizing UK Payment Processor Access in 2026

US payment processors can impose higher fees on cross-border transactions for non-US resident owned LLCs. They may also have stricter KYC (Know Your Customer) requirements or limit payout currencies. UK processors, however, often offer more competitive rates and broader multi-currency support, especially for businesses serving European and global markets.

For example, a typical US processor might charge 2.9% + $0.30 per transaction for international cards, while a UK equivalent could be 1.5% + £0.20. These differences accumulate quickly for high-volume businesses. Accessing UK payment infrastructure diversifies your processing options, reducing reliance on a single region's financial ecosystem.

Most UK payment processors require a UK-registered business entity to open an account. A standalone US LLC, even with a US bank account, typically will not qualify. This is a common barrier for non-US founders seeking to optimize their payment stack.

Attempting to register a US LLC directly with a UK payment gateway usually results in rejection. The system is designed to serve businesses with a physical or registered presence within the UK jurisdiction, necessitating a specific strategic approach.

The most effective way for a US LLC to access UK payment processors is by establishing a complementary UK Limited Company (UK Ltd). This UK entity acts as the interface for your UK payment gateways. The US LLC remains your primary operational entity, but the UK Ltd handles specific payment collection.

Your customers could pay through the UK Ltd's payment gateway. The funds are then transferred from the UK Ltd's UK bank account to your US LLC's US bank account, simplifying compliance and international transfers. This structure is efficient for both sales and accounting.

Stripe UK is a popular choice, offering excellent global coverage and developer-friendly APIs. To open a Stripe UK account, your UK Ltd needs a UK company registration number, a UK bank account, and a UK physical address. Wise Business and Revolut Business also offer services, including multi-currency accounts and virtual cards.

For example, a UK Ltd can obtain a UK bank account with Wise Business. This bank account then serves as the settlement account for Stripe UK. This combination creates a powerful and streamlined payment flow for your US LLC's revenue.

You can form a UK Limited Company remotely, often within 24-48 hours. The process requires a registered office address in the UK and at least one director. Bastion Formations can assist with this setup, ensuring all legal requirements are met.

Expect initial setup costs for a UK Ltd to be around $150 to $300, plus an annual registered agent fee of $100 to $200. Maintaining the UK entity also involves annual compliance filings, which can cost $200 to $500 if outsourced.

Once your UK Ltd receives payments via a UK processor and deposits them into its UK bank account, you need an efficient way to transfer these funds to your US LLC. Services like Wise Business offer competitive exchange rates and low transfer fees for international wire transfers.

Transferring funds from your UK Ltd's Wise Business account to your US LLC's Mercury Bank account, for instance, typically incurs minimal fees, often less than 0.5% of the transaction value. This ensures your US LLC receives its revenue quickly and cost-effectively.

The US LLC will generally be taxed in the US based on its classification (e.g., disregarded entity or partnership). The UK Ltd will be subject to UK corporation tax on its profits, currently 19% on profits under £50,000. It is crucial to have a clear intercompany agreement.

This agreement specifies how the UK Ltd collects funds on behalf of the US LLC, often as a service fee or commission. Consulting with a tax professional specializing in international structures is essential to ensure compliance and avoid double taxation.
