US Limited Liability Companies (LLCs) have become increasingly popular among Portuguese residents seeking to establish or expand their business presence in the United States while maintaining tax efficiency. These entities offer the liability protection of a corporation while potentially benefiting from favorable tax treatment in both countries. The attraction lies in their flexibility, as LLCs can be structured as single-member or multi-member entities, with various options for tax classification.
TLDR
Tax Treatment
Portuguese tax authorities view US LLCs as opaque entities, not pass-through. Income is typically classified as 'other income' rather than dividends.
NHR Benefits
Non-Habitual Residents can claim full tax exemption in Portugal on LLC income, as confirmed by recent tax rulings.
Optimal Structure
Single-member LLC managed outside Portugal, with NHR status, typically provides the most tax-efficient setup.
Required Filings
US tax obligations include Form 1040-NR or Form 1065. Portuguese reporting treats income as foreign-source capital income.
How Portugal Views US LLCs 🇵🇹
Portuguese tax authorities take a distinct approach to US LLCs that differs significantly from their treatment in the United States. This interpretation has evolved through various tax rulings and continues to shape how these entities are taxed in Portugal.
Non-Recognition of Pass-Through Status
Portugal generally does not recognize the pass-through nature of US LLCs that exists under US tax law. According to the landmark 2016 ruling (processo 2360/2016), Portuguese tax authorities established that US LLCs cannot receive pass-through treatment in Portugal unless they qualify under specific exceptions.
Pass-Through Exceptions
- Professional societies (sociedades profissionais)
- Companies for simple asset administration
- Entities explicitly qualifying under Portuguese transparency rules
This means that most US LLCs are treated as opaque entities for Portuguese tax purposes, regardless of their US tax classification. This treatment creates a disconnect between how the entity is viewed in each jurisdiction.
Income Classification
The classification of LLC income in Portugal follows specific guidelines established through various tax authority decisions.
Impact of Recent Tax Rulings
Recent tax authority decisions have provided important clarification on how US LLC income should be treated in Portugal. The most significant recent ruling came in 2024 (Case 26925).
2024 Landmark Ruling
The ruling confirmed that income from US LLCs can qualify for full tax exemption under the Non-Habitual Resident (NHR) regime when properly structured and reported as foreign-source capital income.
Key implications from recent rulings include:
Ruling Implications
- LLC income is classified as foreign-source capital income
- NHR status holders can claim full exemption from Portuguese taxation
- Management location is crucial for determining source of income
- Income must be properly reported as 'other income' rather than dividends
Management Location Considerations
The location from which an LLC is managed can significantly impact its tax treatment in Portugal.
Caution
If an LLC is managed from Portugal, it risks being considered a Portuguese entity, potentially triggering additional tax obligations and losing favorable treatment under the NHR regime.

Optimal LLC Structure for Tax Efficiency
Creating an optimal structure for a US LLC owned by Portuguese residents requires careful consideration of both countries' tax laws and recent rulings. Recent tax authority decisions have provided clarity on the most tax-efficient approaches.

Special Considerations
The ownership of a US LLC by Portuguese residents involves several special considerations that require careful attention to ensure proper tax compliance and risk management in both jurisdictions.
Gift and Inheritance Tax Treatment
Portugal applies stamp duty (Imposto de Selo) rather than traditional inheritance tax on transfers of assets, including LLC interests.
Portuguese Stamp Duty Rates 2024
| Taxable Income | Tax Rate | Additional Information |
|---|---|---|
| Transfers to spouse, children, parents | 0% | Full exemption |
| All other beneficiaries | 10% | On total value transferred |
Notes:
- Applies to Portuguese assets regardless of residency
- No estate tax treaty exists between US and Portugal
Cross-Border Complications
The absence of an estate tax treaty between the US and Portugal can lead to double taxation on inheritance transfers, as both countries may claim taxing rights on the LLC interests.
Double Taxation Risks and Solutions
Several situations can trigger double taxation risks for US LLC owners residing in Portugal.
Common Double Taxation Scenarios
- Income taxed in both countries due to different entity classifications
- Capital gains taxed in both jurisdictions on LLC interest sales
