Spanish doctrine on the US LLC (Feb-2020): what Spain says about it

0290-20. Spanish administrative doctrine on how a US LLC is taxed is decisive for Spanish residents. We review query V0443-19, the line reinforced in Feb-2020, and implications for your IRPF.

Spain's binding ruling V0290-20, dated February 11 2020, is the single document that frames how a US LLC is taxed in the hands of a Spanish tax resident.

If you are a Spanish tax resident and you have a <a href="/en/blog/us-llc-for-non-residents-tax-structure">US LLC</a>, the key question isn't what the <a href="https://www.irs.gov" target="_blank" rel="noopener">IRS</a> says but what Spanish administrative doctrine says about your LLC. Here lies a body of binding rulings from the Directorate-General of Taxes (<a href="https://petete.tributos.hacienda.gob.es" target="_blank" rel="noopener">DGT</a>) and resolutions of the Central Economic-Administrative Court (<a href="https://serviciostelematicosext.hacienda.gob.es/TEAC/DYCTEA" target="_blank" rel="noopener">TEAC</a>) that is absolutely decisive. Let's analyze it precisely.

The underlying tax problem

A US single-member LLC is by default a Disregarded Entity for IRS purposes: it does not tax as its own entity and all its income is attributed to the partner. But Spain is not the United States, and the AEAT must classify the LLC under Spanish law to determine how the resident partner is taxed.

Key technical questions:

  1. Does the LLC have legal personality from the Spanish-law perspective or is it treated as an entity without personality?
  2. Does the LLC itself tax (Non-Resident Income Tax without permanent establishment) or is its income attributed directly to the partner (income-attribution regime, art. 87 LIRPF)?
  3. If the LLC is opaque, are the partner's distributions movable-capital income (dividends) or income from work / economic activity?
  4. Does the Spain-US Double-Taxation Treaty (<a href="https://www.boe.es" target="_blank" rel="noopener">BOE</a> 22-12-1990, modified by Protocol in force since 27-11-2019) apply?
  5. How is double taxation avoided?

The answer to these questions has a direct impact of up to 20 percentage points on your personal tax burden.

The earlier doctrine: opacity and dividends

For years, the DGT considered LLC of non-residents with their own legal personality under US law as opaque entities (similar to a Spanish S.L.). Therefore:

  • The LLC did not tax in Spain on its income (no permanent establishment).
  • When it distributed profits to the Spanish-resident partner, those were classified as movable-capital income (dividends), taxed in the savings base at 19-28%.
  • The Spain-US DTT applied along with double-taxation deduction.

This was favorable to the taxpayer: 19-28% savings base vs. 24-47% general base for economic-activity income.

The shift: query V0443-19 and BOE Feb-2020

In 2019, particularly with Binding Query V0443-19, of 28 February 2019, the DGT introduced more sophisticated analysis that lays the foundation for the line consolidated from February 2020 onward:

> The decisive element to fiscally classify a foreign entity is not its formal legal personality in the country of formation, but a functional comparison with equivalent figures in Spanish law, considering substantive regime (partner liability, asset autonomy, capacity) and tax regime in the country of origin (transparent vs opaque).

Technical conclusion: a single-member LLC treated as Disregarded Entity by the IRS is functionally assimilated to an entity under the income-attribution regime of Spanish law. That is, akin to an unincorporated common-property arrangement: income is imputed directly to the partner according to its nature (economic-activity income, capital gains, etc.).

This line has been consolidated in subsequent queries (V1631-21, V2034-22, V0863-23) and in TEAC resolutions on analogous cases.

What changes for your IRPF

If your LLC is classified as an income-attribution entity:

  • There is no "dividend distribution moment". Income is imputed to the Spanish-resident partner in the year the LLC obtains it, regardless of distribution.
  • Income is imputed by its original nature. If the LLC provides professional services, it is economic-activity income taxed in the general base (24-47%).
  • No dividend-double-taxation exemptions apply. What applies is the deduction for international double taxation (art. 80 LIRPF) only for tax actually paid in the US, which for a Disregarded Entity is typically $0 federal (see <a href="/en/blog/llc-pass-through-with-real-tax-structure">pass-through taxation</a>).
  • LLC deductible expenses are deductible for computing the net imputed result (as in any economic activity).

When the LLC remains opaque

Not every LLC is automatically assimilated to a transparent entity. If your LLC:

  • Has multiple members (Multi-Member LLC) and is treated by default as a Partnership in the US: the line is similar (income attribution).
  • Makes a check-the-box election (Form 8832) to be taxed as a C-Corporation in the US: the situation is different. The LLC would tax as opaque in the US (federal 21%) and Spanish doctrine could classify it as opaque too; distributions would be dividends.

Query V2034-22 reinforces this logic: the US tax regime (transparent or opaque) is the most relevant indicator for the Spanish classification.

For UK readers, the parallel debate has been settled differently: in Anson v HMRC [2015] UKSC 44 the Supreme Court held that a member of a Delaware LLC was entitled to UK double-taxation relief on US tax paid because the member had a direct interest in the LLC's profits as they arose. HMRC subsequently confirmed in its Manual (INTM180020) that LLC continue to be treated as opaque companies for general UK tax purposes, with Anson applied case-by-case to grant credit relief. The practical takeaway is that a UK-resident member of an SMLLC may credit US tax paid against UK income tax even though the LLC is otherwise treated as a corporation for HMRC purposes — a result that is broadly the opposite of the Spanish income-attribution outcome.

Spain-US Double-Taxation Treaty

The Spain-US DTT (BOE 22-12-1990, modified by Protocol BOE 23-10-2019, in force since 27-11-2019) regulates allocation of taxing rights. Key points:

  • Art. 7 DTT: business profits taxed in the residence State unless there is a permanent establishment (PE) in the other State. An LLC without PE in the US and with a Spanish-resident partner does not tax in the US on business profits: it taxes in Spain.
  • Art. 22 DTT: double-taxation elimination clause.
  • Limitation on Benefits (LOB): the 2019 Protocol hardened anti-treaty-shopping clauses, especially impacting opaque LLC structures.

In a Disregarded Entity, the DTT applies directly to the partner (the LLC is transparent), and there is no US tax to deduct.

Operational implications

  1. You need real LLC bookkeeping. You cannot "estimate" net result: you need books, receipts, bank reconciliations.
  2. Your IRPF must declare the imputed net result, not the "remittance" received in your personal account.
  3. Form 720 still applies. Income-attribution regime does not exempt the informational obligation.
  4. Forms 100/130/131. If classified as economic activity, you need quarterly installments like any self-employed person.

Risk of regularization if you've been treating it as dividends

If you've been declaring your LLC flows as savings-base dividends (19-28%) and the AEAT recharacterizes them as imputed economic activity (general base 24-47%), the difference can be very significant. Statute of limitations: 4 years. Penalties: art. 191-195 LGT.

What we see: regularization of non-prescribed periods + interest + minimum 50% penalty (can rise). The Exentax approach is practical: confirm the data, prepare the evidence and close the next step.

Apply the administrative doctrine in the right sequence

  1. Define classification with judgment. Typical case of professional services with single-member LLC: economic activity imputed by income attribution.
  2. Design the structure for tax-efficient operation. Decisions: capital contributions, allocated expenses, partner remuneration, alternative structures (Spanish S.L. + operational LLC, etc.). See <a href="/en/blog/international-tax-design-3-jurisdictions-max-no-cfc">designing a solid international structure</a>.
  3. Consider your specific activity. Different practical regime for services, e-commerce, royalties, trading. Developed in <a href="/en/blog/llc-tax-by-activity-services-saas-and-trading">LLC taxation by economic activity</a>.
  4. Maintain robust documentation. It distinguishes a defensible structure from a vulnerable one.
  5. Avoid simulation. If the LLC lacks substance and services are materially provided by the resident individual, the AEAT can apply simulation, with higher penalty and possible criminal referral. Exentax maps the weak point to a concrete next step inside the client file.

Classify the LLC before calculating the outcome

Spanish administrative doctrine on the US LLC is very specific: in the typical single-member LLC case, the result is imputed to the Spanish-resident partner as economic activity in the general base. This requires serious planning, a documented operating file. Good news: well-designed, an LLC remains an excellent tool to internationalize your business and legally optimize your global tax burden.

The BOE and administrative-doctrine angle is not about finding a magic label for the LLC. It is about proving what the entity really does, who controls it, where decisions are made and whether the tax treatment follows the economic substance of the case.

Apply Spanish doctrine to the actual facts

The February 2020 BOE administrative doctrine reads more usefully when it's treated as a stable interpretive reference rather than as a one-time event. The interpretation it sets out — how the Spanish tax administration looks at US LLC in the hands of Spanish-resident members — has not been substantively reversed in the years that followed, and it remains the practical anchor for any analysis that involves a Spanish-resident beneficial owner of a US LLC.

Operating checkpoint: Spanish doctrine on the US LLC (Feb-2020)

The published Spanish administrative doctrine on LLC reads more usefully as a stable structural reference between vehicle, beneficial owner and treatment of profits and distributions, than as a closed verdict on every situation. The structural reading remains stable across personal cases.

Use administrative doctrine as evidence, not decoration

Thousands of freelancers and entrepreneurs already operate their US LLC legally, with documentation and a clear compliance file. At Exentax we handle the entire process: formation, banking, payment gateways, bookkeeping, IRS filings and compliance in your country of residence. Book a strategic review and we will tell you honestly whether the LLC makes sense for your case, with no absolute promises.

This Spanish ruling only answers a Spanish-resident analysis; it is not a universal LLC doctrine. The same entity can be read differently by another revenue authority, so the tax outcome can flip from pass-through treatment to corporate opacity depending on where the owner actually lives.

How Exentax reads Spanish doctrine before structuring an LLC

Exentax reads Spanish doctrine as operational risk, not as academic noise. When a founder uses a US LLC from Spain, we connect the BOE criterion with residence, attribution, management, banking records and the documents that would have to support the position if it were reviewed.
