From the US with an LLC: Spain DNV

How a US LLC works structurally

A US Limited Liability Company is a state-level business form with federal tax flexibility. Default IRS treatment depends on member count:

• Single-member LLC: disregarded entity. Income flows directly to the owner's Form 1040 (or 1040-NR). No federal entity-level tax. State income tax depends on state of formation and operations.
• Multi-member LLC: partnership. Files Form 1065, issues K-1s to members. Pass-through at the entity level; tax owed at the member level.
• Either, with Form 8832 election: can elect corporate treatment ("check-the-box"). Files Form 1120. Subject to US corporate income tax (21% federal).

The default pass-through treatment is what makes US LLCs popular with American digital nomads. Profits flow to the owner's personal tax return, which is then subject to whatever the owner's residence-state tax rules apply. The Foreign Earned Income Exclusion (FEIE) of $130,000 for 2026 can exclude much of this from US tax for Americans bona-fide-residing abroad.

How Spain treats your US LLC

The structural question for Spanish DNV holders running US LLCs: does Spain's tax authority respect IRS pass-through treatment, or does it look through to the US entity and treat it as a foreign corporation?

The legal default in most civil-law European jurisdictions is to look at the entity's substance and form under Spanish corporate law. A US LLC — with limited liability, capital structure, and corporate-style governance — often resembles a Spanish S.r.l. / S.A. / Ltd. structurally, even though the IRS treats it as a pass-through.

The three positions European tax authorities take

Position 1: Respect IRS pass-through. Spain treats LLC income as if earned directly by the owner. Owner pays Spanish personal income tax on the income. No Spanish corporate-level tax on the LLC. This is the LLC-friendly outcome. Croatia, Romania, and Cyprus generally take this position.

Position 2: Treat as foreign corporation. Spain treats the LLC as a non-resident foreign corporation. LLC income is corporate income, taxed at Spanish rates if there's a permanent establishment (PE), or treated as foreign income with treaty relief. Owner pays Spanish personal tax only on dividends/distributions actually paid. Spain and Italy can take this position.

Position 3: Case-by-case. The tax authority looks at substance: where management decisions are made, where employees work, where revenue is generated. If the LLC's management and operations are clearly in Spain, it may be deemed a Spanish tax-resident entity regardless of US-side treatment. This is the riskiest outcome — the LLC becomes a fully-taxable Spanish corporation.

Practical setup for Spain DNV holders

The cleanest US-LLC setup for a Spanish DNV applicant typically involves:

1. Maintain the LLC's US substance. US registered agent, US business address, US bank account, US-facing contracts where possible. The more the LLC looks like a genuine US business with US operations, the harder it is for Spain to deem it a Spanish entity.
2. Don't sole-source revenue from Spanish clients. If 100% of LLC revenue comes from Spanish sources, Spain has a strong case for PE assertion. Diversified non-Spanish revenue helps.
3. Salary, not just distributions. Many advisors recommend the LLC pays a reasonable salary to the owner for Spanish services rendered, with the salary subject to Spanish tax in full. This satisfies both IRS "reasonable compensation" rules for S-corp elections and Spanish substance tests. The residual profit flows as pass-through or distributions.
4. Use the US-Spain tax treaty. Most US-Spain double-tax treaties contain provisions for relieving double taxation on the same income stream. Treaty-residence tie-breaker rules apply if you become Spanish tax resident.
5. Get a tax opinion in writing. For LLC income above ~$100,000/year, a tax opinion from a cross-border specialist (US-Spain bilateral expertise) is worth the $3,000–$8,000 cost. The exposure on a deemed-corporation outcome can run 15–30% of LLC profits in Spanish corporate tax.
