US LLC & UK Ltd for Brazilian Founders: Tax & Banking in 2026

A US LLC, particularly in states like Wyoming or Delaware, provides credibility and access to the vast US market. It simplifies integration with major payment processors like Stripe and PayPal, which often have easier onboarding for US entities. This access is vital for selling digital products or services globally.

For Brazilian non-resident founders, a US LLC generally operates as a disregarded entity for US tax purposes if it has no US economic nexus or US partners. This means profits pass through directly to the owner, who reports them on their personal tax return in Brazil. No US federal income tax is typically owed if income is foreign sourced.

The UK Limited Company is an excellent vehicle for accessing European markets and establishing a strong international presence beyond the US. It is perceived as credible and stable, facilitating partnerships and banking relationships outside of North America. Many payment gateways are more amenable to UK registered businesses for EU transactions.

A UK Ltd allows Brazilian founders to manage their European and potentially other international revenue streams separately from their US operations. This separation can simplify accounting and compliance, especially regarding VAT. It also provides a legal framework under UK law.

As a non-resident sole owner of a US LLC, you generally won't pay US federal income tax on foreign-sourced income. However, you must file Form 5472 and a pro-forma Form 1120 annually. Failure to file these can result in a $25,000 penalty, even if no tax is due. This is a critical compliance requirement.

For US-sourced income, a 30% withholding tax typically applies unless reduced by a tax treaty. However, most Brazilian founders will structure their US LLC to earn foreign-sourced income. If you do have US-sourced income, you will also need an ITIN to file a US tax return (Form 1040-NR).

A UK Limited company is subject to UK Corporation Tax on its worldwide profits. The main rate of Corporation Tax in the UK is currently 25% for profits over £250,000, with a small profits rate of 19% for profits up to £50,000. These rates apply to the company's net profits before distribution.

Brazilian founders owning a UK Ltd will need to submit annual accounts and a Corporation Tax return (CT600) to HMRC. Dividends paid from the UK Ltd to a Brazilian resident shareholder may be subject to tax in Brazil, potentially with credit for any UK dividend tax paid, depending on the Brazil-UK tax treaty.

For your US LLC, Mercury is an excellent option for remote US banking, accessible to non-US residents. Brazilian founders can open a Mercury account without visiting the US. You will need your EIN and Articles of Organization. Mercury offers FDIC-insured accounts, virtual cards, and integration with US payment processors.

Your UK Limited company benefits immensely from a Wise Business account. Wise (formerly TransferWise) allows easy opening of multi-currency accounts from Brazil, providing UK bank details for receiving payments in GBP. It offers competitive exchange rates for international transfers, which is crucial for managing funds between your entities and personal accounts.

Both the US Foreign Account Tax Compliance Act (FATCA) and the Common Reporting Standard (CRS) apply to Brazilian founders with international entities. US financial institutions report accounts held by foreign persons to the IRS under FATCA. Non-US financial institutions in CRS signatory countries (like the UK) report accounts held by tax residents of other signatory countries (like Brazil) to their local tax authorities, which then share the information with Brazil.

This means the existence and financial activities of both your US LLC and UK Ltd will likely be reported to the Brazilian tax authorities. Transparency and accurate reporting in Brazil are paramount to avoid penalties. Ensure your Brazilian tax advisor is aware of your international structure.

Consider using your US LLC for revenue streams primarily from North America and your UK Ltd for European or other international revenue. This helps to segment your income based on geographical origin and streamline compliance. For example, a US LLC could receive payments from US customers via Stripe, while a UK Ltd receives payments from EU customers via another gateway linked to its Wise account.

Funds can be transferred between the US LLC and UK Ltd as intercompany loans or service payments, which must be clearly documented with arm's length pricing. Dividends from the UK Ltd would be sent to your personal Brazilian bank account or potentially to your US LLC if it's acting as a holding company, though this adds complexity not typically needed for most startups.
