How We Help US Citizens Navigate Taxes When Applying for Portugal’s Golden Visa

A Path to European Residency With Confidence

For many affluent Americans, Portugal’s Golden Visa offers a rare combination: EU residency, minimal relocation requirements, and a potential pathway to citizenship without needing to uproot your life. But while the travel and lifestyle benefits are clear, there’s a less obvious layer of complexity: navigating the U.S. tax system while investing abroad.

At Citizenship360, we work closely with high-net-worth U.S. clients to simplify this process. We coordinate with U.S. tax experts, vet tax-efficient funds, and ensure every step—from investment to reporting—is structured with compliance and clarity in mind.

Let’s unpack what that really means.

What’s Changed? Understanding Portugal’s Golden Visa in 2025

In 2023, Portugal eliminated real estate as a qualifying option for the Golden Visa. Today, eligible investment routes include:

• €500,000 or more into a regulated Portuguese investment fund
• Capital injection into a Portuguese company that creates jobs
• Contributions to scientific research or cultural preservation

The investment fund option is by far the most popular route for U.S. applicants in 2025. It offers clear legal oversight, passive exposure to the local economy, and, if selected properly, better alignment with U.S. tax rules.

The visa itself still has light physical presence requirements:

• 7 days in Portugal in year one
• 14 days during each subsequent two-year period

After five years, you can apply for permanent residency or citizenship, regardless of whether you ever lived in Portugal full time.

US Tax Challenges: PFICs, Form 8621, and the IRS

Here’s the thing. The IRS doesn’t care if your fund is Golden Visa approved. If you’re a U.S. taxpayer and you own shares in a non-U.S. investment fund, it likely qualifies as a Passive Foreign Investment Company (PFIC).

That’s where things get messy.

PFICs are taxed harshly by default. Unless you make the right elections and get the right paperwork from the fund, your gains may be taxed at ordinary income rates with interest charges that stack over time.

Key issues include:

• IRS Form 8621 must be filed every year for each PFIC you own
• The Excess Distribution regime taxes gains across multiple years and penalizes late reporting
• A QEF (Qualified Electing Fund) election can provide relief, but only if the fund supplies annual PFIC statements

Get it wrong and you’re left with a paperwork nightmare and potentially a large, unexpected tax bill. Get it right and you’ll stay compliant while minimizing friction.

That’s why we work only with vetted funds that understand U.S. tax obligations and are willing to provide the necessary documentation.

Portuguese Tax Residency: When It Starts to Matter

Portugal treats tax residency separately from Golden Visa residency. You only become a Portuguese tax resident if:

• You spend 183 or more days in the country in any 12-month period, or
• You have a habitual home there on December 31

If you remain a non-resident for tax purposes, Portugal does not tax your global income. It only taxes income sourced in Portugal, such as rental income or local capital gains.

For those who do become residents, the situation depends on your tax regime.

TISRI: A New Option for New Residents

The TISRI regime (Tax Incentive for Scientific Research and Innovation) replaced the older NHR scheme in 2024. It’s more targeted and applies primarily to:

• Scientific or research professionals
• Tech or innovation sector workers
• Qualifying startup founders or employees

If eligible, you could benefit from:

• 20 percent flat tax on Portuguese employment or business income
• 0 percent tax on most foreign-source income for up to 10 years

This makes full relocation more attractive but only for those who qualify under the regime’s criteria.

Dual Reporting and Compliance Headaches

U.S. citizens must report foreign holdings and accounts, regardless of residency.

If your Golden Visa fund investment is held directly or via a foreign account, you’ll likely need to file:

• FBAR (Foreign Bank Account Report) if total foreign accounts exceed $10,000
• FATCA Form 8938 if foreign assets exceed $200,000 (unmarried) or $400,000 (married)

Add that to the annual Form 8621 for PFICs and you’re looking at a multilayered compliance regime.

Our role is to simplify that. We help you structure your investment smartly, often via a U.S. LLC or other entity, and ensure you have a trusted U.S. tax advisor handling the reporting on both sides.

Case Study: John from New York

John is a 45-year-old tech founder from Manhattan. He wanted EU residency as a long-term hedge and lifestyle option but without moving right away.

Here’s how we helped:

• Investment: €500,000 in a Portuguese venture capital fund with PFIC-friendly reporting

• Tax Team: U.S. expat CPA handled Form 8621 and FATCA filings
