US LLC taxation in Spain: the DGT's three attribution tests

What Spain's February 2020 BOE resolution actually says about foreign entities: tax classification, legal identity, retained profits and evidence for your LLC.

A US LLC can give your business a clear legal home for contracts, ownership, investment and international banking. If you are tax-resident in Spain, a separate question needs a reliable answer: how does Spain classify that entity for tax purposes? Neither the letters LLC nor the location of its bank account settles the issue.

Spain's Directorate-General for Taxation, known as the DGT, set out a framework on 6 February 2020 for assessing foreign entities. Understanding that framework helps you align the company, its owners and its reporting from the outset. This article explains the Spanish position; it does not apply Spanish rules to readers resident elsewhere.

The February 2020 BOE resolution: the document that matters

The official reference is BOE-A-2020-2108, published on 13 February 2020. It is an interpretative DGT resolution about foreign entities and Spain's income-attribution regime. It is not a court judgment, a TEAC decision or an individual ruling written exclusively about LLCs.

The official BOE text distinguishes the document's date, 6 February 2020, from its publication and effect. Section VI makes it binding on the tax administration's implementing bodies from publication and applies its effects to taxable events accruing from that date.

For an established LLC, this is a reason to review the relevant year properly. A present-day summary should not simply be copied across every historical return. The resolution describes an evolution in administrative reasoning; it does not establish that all LLCs were previously treated as opaque corporations.

The DGT's three tests for foreign entities

Section V identifies three characteristics that must be present. They concern the entity's actual tax treatment in its jurisdiction of formation, rather than how its name translates into Spanish.

Identify the taxpayer, not just the amount of tax paid

To meet this criterion, the entity must not itself be a taxpayer under a personal income tax in its formation jurisdiction. The test concerns liability under the regime, not merely whether any tax was payable that year.

An entity can be subject to income tax and owe nothing because it has losses. That does not make it transparent. Equally, the absence of withholding on a bank payment does not determine the entity's classification.

The relevant question is who is treated as the taxpayer under the applicable rules. An EIN letter is useful identification, but does not replace evidence about members, elections and tax treatment. A state maintenance charge also answers a different question from federal income-tax classification.

Establish whether attribution depends on a distribution

The second test separates income earned from cash transferred to an owner. Under an attribution regime, income can belong to the member for tax purposes when it arises, even though the company keeps the money.

Retaining funds can support hiring, investment and working capital. Its business purpose remains entirely valid; the tax timing needs its own analysis. Our guide to LLC pass-through taxation explains why an owner withdrawal should not automatically be described as a corporate dividend.

Preserve the character of each income stream

Service fees and investment income do not automatically become the same type of income because they enter one LLC account. The third test concerns the character of the activity or source in the hands of each member.

Article 88 of Spain's Personal Income Tax Law reflects that distinction. The contract and the underlying transaction matter. A bank statement showing a generic incoming transfer is not enough to classify what the payment represents.

Tax transparency does not erase the LLC's legal identity

A US LLC is formed under state law. Its tax classification does not automatically remove its contracts, ownership of assets or membership arrangements.

The Spanish resolution explains why looking for a foreign legal form identical to a Spanish one is not sufficient. Its historical discussion includes a UK LLP with its own legal personality. That example illustrates the reasoning; it is not an LLC-specific ruling.

This is a useful distinction for business owners: legal identity and tax treatment answer different questions. A company can have its own accounts and contractual relationships while its income is attributed to members for tax purposes. The extent of limited liability depends on the relevant law and the way the entity is operated, not on a tax label alone.

Single-member, multi-member and corporate elections

The IRS's single-member LLC guidance describes the federal starting point. A single-member LLC is generally disregarded for federal income tax unless it elects corporate treatment. An LLC with two or more members is generally classified as a partnership by default, subject to valid elections and any applicable special rules.

Those are US classifications. Applying the Spanish resolution means examining the effective regime against all three DGT criteria. Headcount alone does not replace the analysis.

Foreign-owned describes ownership, not a separate tax election. Member count and effective elections determine the federal starting point described above. The owner's residence and the company's formation jurisdiction are also separate pieces of information.

Where Form 8832 has been used, check the election, its effective date and the consequences in both countries. A corporate election is not a decision to make by comparing one headline rate. Future distributions, changes of ownership and the business plan belong in the same assessment.

Retained profit and owner withdrawals: a worked example

Consider an illustrative single-owner LLC whose owner is tax-resident in Spain and whose regime qualifies for income attribution. It earns EUR 40,000 and incurs EUR 10,000 of expenses assumed, for this example, to be fully deductible under the applicable rules. The resulting profit is EUR 30,000.

If the owner withdraws EUR 12,000 and EUR 18,000 remains in the business, the withdrawal does not turn the profit into EUR 12,000. If the owner withdraws nothing, that alone does not turn the EUR 30,000 result into zero. The actual calculation still depends on the correct income, expenses and period.

Keeping funds available can be commercially sensible. Buying an asset, however, may require depreciation rather than an immediate deduction of its entire price. The LLC deductions guide explains how expenditure and supporting records fit together.

Where the properly calculated tax result is zero, there is no positive profit from that activity to attribute for the period. Other income and filing requirements are considered separately. No sales, no receipts, no distributions and no profit are four different situations.

Why Form 5472 and a pro forma 1120 do not change this analysis

A foreign-owned US disregarded entity is treated separately for the limited purposes of section 6038A. The Form 5472 instructions explain the information-reporting rules and the accompanying pro forma Form 1120.

That pro forma return is not a corporate election under Form 8832. It also does not, by itself, determine the Spanish treatment of the entity. The forms perform different jobs.

Reportable owner transactions can exist without sales, including contributions and distributions. Keeping bank statements and records of owner funding from formation makes the annual preparation clearer. It also separates commercial revenue from money introduced by the member.

The US-Spain treaty adds another layer of coordination

Article 1.6 addresses income received through fiscally transparent entities. Applying it requires identifying the resident to whom the income belongs and satisfying the treaty's conditions. Having an EIN is not automatic treaty eligibility.

Article 7 concerns business profits, Article 17 limitation on benefits and Article 24 double-tax relief. Our US-Spain tax treaty guide explains their practical use for different income streams.

Entity classification, income source and foreign tax actually paid are connected but distinct issues. Where a service is performed matters; the customer's address and the payment currency do not replace that analysis. VAT, social security and asset-reporting questions are assessed separately where relevant.

Reading DGT rulings and TEAC decisions properly

An individual binding tax ruling answers a stated set of facts. Article 89 of Spain's General Tax Law governs its effects, including application to other taxpayers with identical facts and circumstances, subject to the statutory conditions.

A useful review reads the full answer and checks the year, entity, member residence and tax being considered. A ruling number on its own does not show that the conclusion applies to your LLC.

TEAC is a different administrative review body from the DGT. Attributing a position to it requires an identifiable decision and its actual scope. Sound advice makes that chain of reasoning visible instead of using institutional names as a substitute for evidence.

Turning the classification into a workable structure

At Exentax, we start with the business you actually have or intend to build. We examine formation documents, the Operating Agreement, membership, tax elections and the dates of relevant changes. We then connect those facts with the contracts, income streams and owners' residence.

The purpose is a position you can understand and support: which treatment applies, what evidence it rests on and how to coordinate the LLC with the professionals handling your Spanish taxation. Banking, payment arrangements and investment accounts should fit that position.

Questions about Spain's 2020 resolution and US LLCs

Is the BOE resolution exclusively about LLCs?

No. It establishes criteria for foreign entities. Applying it to an LLC requires reviewing its effective tax regime and the characteristics identified in the resolution.

Does disregarded mean the LLC is no longer a company?

No. It is a classification for particular US tax purposes. The LLC's legal existence and its tax treatment must be considered separately.

Does keeping profit inside the LLC prevent attribution in Spain?

Not by itself. Where the income-attribution regime applies, income is attributed under its rules even if retained by the entity. Distributions and the calculation of profit are different matters.

Does filing a pro forma Form 1120 turn the LLC into a corporation?

No. Its use alongside Form 5472 fulfils specific information-reporting requirements. It is not equivalent to a corporate tax election using Form 8832.
