Americans Freelancing in Portugal: Keep US LLC or Go Local?

Imagine this scenario: you're freelancing with a US LLC and have decided to relocate to Portugal. The next steps might not be as straightforward as one would hope. Deciding whether to maintain the existing structure or switch to a local setup can quickly become complicated, with tax regulations, compliance rules, and bureaucratic hurdles to complicate things.

There are important considerations when working as a freelancer in Portugal, along with several practical concerns, from handling income taxes and understanding how to apply for a digital nomad visa, to determining whether it’s necessary to adjust the business structure to meet Portuguese tax and legal requirements. But apart from that, for many American freelancers, the question remains: continue operating through a US LLC, or establish a Portuguese structure like a trabalhador independente or an LDA? This is exactly what we’ll explore in this article.

Key Differences Between US and Portuguese Freelancing Structures

US LLC (As a Freelancer Tool)

A US LLC (Limited Liability Company) is a popular structure for many freelancers because of its flexible and protective nature. Here’s why freelancers often choose an LLC:

• Pass-through taxation: The LLC itself doesn’t pay taxes. Instead, profits “pass through” to the owner’s personal income tax return, simplifying tax filings.
• Limited liability: An LLC provides personal liability protection, ensuring that personal assets are separate from business liabilities.
• Separate finances: Many freelancers use their LLC to separate personal and professional finances, which can be useful in the context of bookkeeping, taxes, and financial planning.

While these benefits make it appealing to maintain one’s LLC abroad, there are some international tax implications to consider when relocating to Portugal.

Portuguese Options

In Portugal, freelancers have several structures to choose from, including trabalhador independente, LDA, and unipessoal LDA. Here's a brief breakdown:

• Trabalhador Independente (Sole Trader): This is the simplest structure for individuals working as freelancers. It’s similar to being a sole proprietor in the US and is ideal for individuals who are looking for minimal bureaucracy.
• LDA (Sociedade por Quotas): This is Portugal’s LLC equivalent in Portugal. It allows for a more formal business structure with limited liability but comes with increased administrative requirements.
• Unipessoal LDA (One-Person Company): A one-person LDA that operates similarly to a small LLC. It provides limited liability but is simpler to establish than a multi-member LLC.

Key Questions to Help You Decide

When considering whether to maintain your US LLC or transition to a local structure in Portugal, the following questions may offer some guidance.

Where Are You a Tax Resident?

If you spend more than 183 days in Portugal, you are considered a Portuguese tax resident and must declare all worldwide income, including any income from the US LLC. Portuguese tax authorities expect a report on this income, which could be subject to Portuguese taxation, depending on the nature of your income and whether you qualify for Portugal's NHR tax regime.

Where Are Your Clients?

• US-based clients: If most of your clients are in the US, maintaining your LLC might make the most sense. This setup allows for easier contracts and invoicing, especially for tax purposes.
• EU-based clients: If your clients are mainly in the EU, having a local Portuguese setup could simplify invoicing, VAT, and other legal requirements. Additionally, many European clients prefer dealing with EU-based entities.

Are You Under the NHR (Non-Habitual Resident) Regime?

Portugal's NHR tax regime stands out as one of the country’s main incentives for new residents. For those who qualify, it offers a 20% flat tax rate on specific types of income. However, business income generated through a US LLC may still be treated as Portuguese-source income if the activities are managed from Portugal, even under the NHR. This distinction plays an important role in assessing whether it makes sense to maintain the US LLC or transition to a local structure.

How Much Complexity Feels Justifiable?

Managing a US LLC while residing in Portugal comes with dual tax filing obligations: one with the IRS and another with Portuguese authorities. Additional reporting requirements, such as FBAR and FATCA, apply to US citizens with foreign accounts (regardless of how their business is structured). In contrast, Portuguese options like trabalhador independente or an LDA simplify the paperwork and compliance process but come with their own set of challenges.

Planning to Stay Long-Term?

If you're planning a long-term stay or eventual citizenship in Portugal, switching to a local business structure can be advantageous. It may ease integration into the Portuguese tax and social security systems, where local contributions are often required. Additionally, some benefits of Portuguese residency—such as the NHR regime—can be more effectively accessed or optimized through a local setup. 

How Portugal Views US LLCs

While US tax law sees LLCs as pass-through entities (meaning profits are reported on your personal tax return), Portugal takes a different approach.

Under Portuguese law, an LLC is generally seen as an opaque entity. This means income from the LLC is classified as "other income," rather than dividends or self-employment/business income. This distinction matters significantly, especially if you’re under the NHR (Non-Habitual Resident) regime. 

A December 2024 ruling clarified that foreign-sourced "other income" may be exempt from Portuguese tax under NHR, but only if certain conditions are met. Most importantly, your LLC must not be effectively managed from Portugal—making decisions or running daily operations from Portugal likely means that its income is not seen as foreign-sourced. NHR benefits would not apply in that case. Likewise, having a permanent establishment in Portugal, like an office, risks local taxes.

Other risks include:

• Double taxation if exemptions aren’t applied correctly.
• Corporate residency risk if the LLC is seen as Portuguese.
• Transfer pricing issues with cross-border invoicing.
• Compliance costs from managing US and Portuguese obligations.
• Banking and currency complications.

Practical Steps for Each Option

If Keeping Your US LLC

• Register as a foreign income earner: Go to the Portuguese tax office (Autoridade Tributária) and register as a foreign income earner.
• Declare income: Report your US LLC income on your Portuguese tax return. Make sure to meet the annual tax filing deadline (30th June).
• Get a NIF and VAT ID: You’ll need a Portuguese tax number (NIF) for any official dealings and, if required, a VAT ID.
• Consider a fiscal representative: If working with EU clients, it’s often easier to invoice through a Portuguese fiscal representative.

If Switching to a Portuguese Setup

• Apply for a NIF: If you don’t already have one, apply for a Portuguese tax number.
• Register as trabalhador independente or set up LDA: Depending on your business structure, register accordingly with the Portuguese tax office.
• Understand VAT obligations: As a freelancer or LDA, you might need to charge VAT on your services, depending on your turnover.
• Enroll in Social Security: Freelancers are required to obtain a Portuguese Social Security Number and contribute to the system. If you're a US self-employed person, consider applying for the US-Portugal Totalization Agreement to avoid double contributions.

Mixed Structure (Hybrid)

• Keep the LLC for US clients: Continue invoicing US clients through your LLC.
• Open Portuguese freelancer status for EU clients: Register as trabalhador independente or an LDA for clients within the EU to ensure VAT compliance.
• Maintain clean bookkeeping: Keep separate records for US and Portuguese income to avoid confusion during tax season.

Tax Tips & Pitfalls

• Optimize the NHR regime: If you're eligible for Portugal's NHR tax regime, structure your income to maximize the tax benefits.
• Track all expenses: Whether you're keeping your LLC or transitioning to a local setup, track all deductible expenses to lower your tax burden.
• Avoid double taxation: The aforementioned US-Portugal tax treaty can help you avoid double taxation, but be sure to consult with a tax professional to ensure proper reporting.
