US LLC taxation by country of residence: what you pay where you live

A US LLC can be federally transparent, but the real answer is in your country of residence: attribution, CFC rules, reporting and local tax treatment.

An LLC is not taxed the same way for everyone: real savings depend on residence, CFC rules, attribution, reporting and documentary evidence.

The fundamental principle: taxation by residence

Most countries tax their residents on worldwide income. This means you must declare all LLC profits in your country, not just what you earn locally.

A well-structured LLC allows you to:

• Deduct legitimate business expenses before calculating taxable income
• Apply double taxation treaties between your country and the US
• Optimize the timing of distributions
• Document everything professionally for clean local tax declarations

Spain: IRPF and foreign assets

If you live in Spain, LLC profits are subject to IRPF as income from economic activities.

IRPF progressive rates:

• Up to €12,450: 19%
• €12,450 - €20,200: 24%
• €20,200 - €35,200: 30%
• €35,200 - €60,000: 37%
• €60,000 - €300,000: 45%
• Above €300,000: 47%

In practice:

• LLC generates income and has deductible expenses (software, tools, professional services, Registered Agent, etc.)
• Net profit (income minus expenses) is declared in Spain
• Taxable base is lower thanks to documented deductions
• Spanish tax resolution <a href="https://petete.tributos.hacienda.gob.es" target="_blank" rel="noopener">DGT</a> V0290-20 addresses treatment of foreign entity income

Additional obligations:

• Modelo 720 for foreign assets exceeding €50,000 (bank accounts, investments, real estate)
• Compliance with IRPF declaration requirements

Example: €72,000 gross income → €18,000 deductions → €54,000 declared → ~€12,000 IRPF + €1,500 LLC maintenance = €13,500 total (18.75% effective vs. 35.1% as autónomo)

Mexico: ISR and applicable regime

For tax residents in Mexico, LLC income is subject to ISR (Impuesto Sobre la Renta).

ISR rates for individuals: 1.92% to 35% (progressive)

In practice:

• Foreign-source income declared in annual return
• Mexico has a tax treaty with the US preventing double taxation
• LLC deductible expenses reduce taxable base

Important considerations:

• Mexico is strict with REFIPRES (Preferential Tax Regimes). Proper LLC structuring is essential for compliance
• SAT (Mexican tax authority) has been increasing scrutiny of foreign entities
• Proper documentation of all LLC transactions is critical

Colombia: income tax and CRS

Colombia taxes worldwide income of its tax residents.

Income tax rates for natural persons: 0% to 39% (progressive)

In practice:

• Colombia has a tax treaty with the US
• LLC deductible expenses reduce taxable base
• Distributions declared in annual income tax return
• DIAN (Colombian tax authority) requires declaration of foreign assets

Practical advantage: A Colombian freelancer billing in USD through a US LLC has access to US banking (Mercury), professional payment processing (Stripe US), and asset protection unavailable to a local freelancer.

Argentina: income tax and personal assets

Argentina has one of the highest effective tax rates in the region.

Impuesto a las Ganancias rates: 5% to 35% (progressive)

In practice:

• LLC income declared in Impuesto a las Ganancias
• Impuesto sobre Bienes Personales may apply to foreign assets (including LLC and bank accounts)
• Argentina has no tax treaty with the US
• BCRA currency controls make the LLC structure particularly attractive — you operate in USD without BCRA exchange rate restrictions

Practical advantage: For Argentine freelancers, the LLC provides access to US banking without BCRA exchange controls. The gap between official and parallel exchange rates can make the structure valuable from an operational standpoint, but the tax result still depends on residence and reporting.

Chile: income tax

Impuesto Global Complementario rates: Up to 40% for the highest bracket.

In practice:

• Chile has a tax treaty with the US
• Foreign income declared in annual return
• LLC deductible expenses reduce taxable base

Common principles across all countries

1. The LLC optimizes, not eliminates, your tax obligation. You reduce taxable income through deductions and operate with a more efficient structure.
2. Documentation is everything. Invoices, contracts, expense records, distribution documentation, without documentation, no deductions.
3. US compliance protects you locally. Filing Form 5472 and maintaining BOI Reports demonstrates to your local tax authority that your structure is legitimate and transparent.
4. Every situation is different. Your effective tax rate depends on income, expenses, country, specific tax regime, and dozens of variables requiring case-by-case analysis.

Jurisdiction map

• Spain (LIRPF/LIS). An operative single-member disregarded LLC (real services, no significant passive income) is generally treated under income attribution (art. 87 LIRPF): the LLC's net profits are attributed to the member in the year they arise and integrated into the general IRPF base. If instead the LLC elects corporation treatment (Form 8832) and is controlled by a Spanish resident with mostly passive income, the CFC regime (art. 91 LIRPF for individuals, art. 100 LIS for companies) can apply. The choice is not optional: it depends on economic substance, not on the label.
• Information returns. US bank accounts with average or year-end balance >€50,000: Form 720 (Law 5/2022 after CJEU C-788/19, 27/01/2022, penalties now under the general LGT regime). Related-party transactions and dividend repatriation: Form 232. US-custodied crypto: Form 721. At Exentax we map the exposure early, prepare the reasonable-cause file and reduce avoidable escalation before the authority controls the timeline.
• Spain–US tax treaty. The treaty (<a href="https://www.boe.es" target="_blank" rel="noopener">BOE</a> 22/12/1990, Protocol in force 27/11/2019) governs double taxation on dividends, interest and royalties. An LLC without a permanent establishment in Spain does not by itself create a PE for the member, but effective management can if all activity is run from Spanish territory.
• Mexico, Colombia, Argentina and other LATAM jurisdictions. Each has its own CFC regime (Mexico: Refipres; Argentina: foreign passive income; Chile: art. 41 G LIR). Common principle: profits retained inside the LLC are deemed received by the member if the entity is treated as transparent or controlled.

Country-of-residence analysis is the part that makes or breaks the LLC. The same US entity can be treated differently depending on transparency rules, attribution regimes, CFC rules, reporting duties and how profits are documented locally.

• The same LLC reads differently by residence country. Spain, Mexico, Argentina, Andorra or Portugal can treat retained profits, distributions, reporting and CFC risk in very different ways. Banking must be selected after that residence analysis, not before it.
• Account location is not the whole story. What matters is who owns the account, which entity provides the service, what self-certification was given and how money ultimately reaches the resident owner.
• Keep distributions visible and intentional. If profits are retained in the LLC, record the reason. If they are distributed, route them cleanly and document them. That is often more important than chasing the fashionable fintech of the month.
• Exentax adapts the stack to the country file. The account setup for a Spanish resident owner is not automatically the same as for a founder in Andorra or Latin America.

Local tax tests that matter

Residence is the variable that changes the whole LLC equation. The same US entity can be read as transparent, opaque, attributed, controlled, ignored or taxable depending on where the owner lives and how the business is managed. We map that country layer first, then decide whether the LLC is a tool or a problem.
