Form a US LLC as a Portuguese citizen

Last updated: August 2026

Bottom line

Form a US LLC as a Portuguese citizen is straightforward once the Portugal paperwork is in order. As a Hague Convention member, Portugal issues a single apostille that the US recognizes without further legalization. Tax treaty: US-Portugal treaty (1994) caps dividend withholding at 5·15% and royalty withholding at 10%.

NHR + US LLC stack works well if structured before NHR application. The order matters; do not retrofit. This is the country-specific guide for Portuguese citizens to form a us llc, apostille, banking, and treaty notes that change by jurisdiction. For the canonical procedural sequence (the steps everyone follows regardless of citizenship), see the main US LLC formation page.

A Wyoming or Delaware LLC is the cleanest holding entity for a non-resident founder. No state income tax, no minimum capital, no resident director requirement. The whole setup runs remote: file Articles online, fax Form SS-4 for the EIN, open Mercury for banking. The catch is the annual Form 5472 filing, miss it and the penalty is USD 25,000.
