Declaring US LLC Income in Your Home Country's Tax Authority — Guide for Foreign Owners (2026)

Many foreign US LLC owners believe that since they have an "American company," only the American tax regime is relevant. This is incorrect and dangerous assumption.

Most European tax laws define you as tax resident if:

• You have a permanent address in your home country, or
• You spend more than 183 days in the country over 12 months, or
• Your center of vital interests is in your home country (family, primary income, property)

As a tax resident, you must declare all your income — from home and abroad — in your annual tax return.

US LLC income is "foreign-source income" and must enter the return. Non-declaration is tax evasion — punishable by fines and in severe cases criminal prosecution.

Key concept is "disregarded entity." In US tax system, single-member LLC isn't taxed separately — IRS treats LLC income and expenses as directly belonging to the owner.

Most European tax systems also don't recognize US LLC as separate legal entity for tax purposes when it's single-member. This means:

• US LLC income is considered your personal income
• Declared in your personal annual return
• Taxed at personal income tax rates
• NOT treated as dividend (that would be concession to separate company)

This is opposite of domestic corporation structure — local corp is separate legal entity, pays corporate tax, and only distributed dividends are your personal income.

Exception: if US LLC is multi-member (with partners), treated as partnership in US and as "transparent entity" locally — income still directly attributed to owners proportionally by shares.

Foreign owners with US LLC typically operate in one of two structures:

Structure A: Individual Directly Owns US LLC

You → (own) → US LLC → (generates) → Income

• Income declared as your personal income
• Taxed at personal income tax rates
• If self-employed — pay social security on net income (combined 20-28% effective)

Structure B: Local Corporation Owns US LLC

You → (own) → Local Corp → (owns) → US LLC → (generates) → Income

• US LLC income enters local corp revenue
• Local corp pays corporate tax on profit
• On distribution of dividend to you — additional dividend tax
• Combined effective taxation typically 10-20%

Which Structure for What Case

• Small freelance/consulting (under ~€30K/year): Structure A as self-employed is simpler. Minimal administrative overhead.
• Medium/large income (€30K-200K/year): Structure B often more tax-efficient — savings on lower rate compensate for corporate maintenance costs.
• Very large income (€200K+/year): Consult tax specialist — optimization options through international structures become more diverse.

For Structure A (individual with direct US LLC), most European tax returns have a dedicated section for foreign income.

Which Sub-section to Use

Depends on activity nature:

• Foreign employment income. Not applicable for US LLC owner.
• Foreign self-employment/professional income. Most common category for SaaS, consulting, freelance services owners with US LLC.
• Foreign capital income. For specific activities like stock sales, US property rental.
• Foreign dividends. NOT for US LLC income (it's not dividends). Yes, if you have US C-Corp and paid yourself dividend.

What to Fill

• Gross amount of income received during the year
• Deductible expenses (varies by country and category)
• Social security paid
• Date of income receipt (typically date of transfer to home account or receipt in Wise/Revolut)
• Source country: USA
• Tax withheld abroad (if any — for typical foreign owner without USTB this is $0)

Important: declare gross amount of all receipts — not net LLC profit after US expenses. In your home return, use local rules for deductions, not US bookkeeping.

Most European tax returns have a section for declaring tax treaty benefits when you paid income tax in the foreign state (US in this case) and want credit against home tax.

When You Need This

For most foreign owners with single-member US LLC without USTB — NOT needed, because you didn't pay US federal income tax. If you:

• Paid nothing in US → don't file this section
• Paid $0 because LLC had no activity → don't file
• Paid small amount of state tax (rare but possible in certain states) → fill in

When Completed

If you paid US federal income tax (have USTB/ECI), fill:

• Source country: USA
• Income type: matches your main foreign-income section
• Gross income abroad
• Tax paid abroad (in local currency, at official exchange rate on payment date)
• Double taxation avoidance method: per US-home tax treaty, usually "credit" method

With "credit" method, local tax reduces by amount paid in US, but no more than the local tax on the same income.

Most common category for foreign US LLC owners is "self-employed freelancer."

Registration Locally

• Self-employment declaration — filed within short window of starting activity
• Choice of social security base — between minimum and maximum
• Monthly advance payments
• Activity can be registered as free profession if intellectual (consulting, design, programming, writing)

Annual Obligations

• Annual tax return: by standard annual deadline
• Social security reconciliation: within annual return, based on actual income
• Electronic filing discount often available

Typical Case Calculation

John is a SaaS freelancer with Wyoming LLC. Annual income through LLC: $60,000 (~€55,000).

• Gross income declared: €55,000
• Normative deductible expenses (varies): -€13,750
• Social security base: €41,250
• Social security: ~€7,000 annually
• Tax base: €41,250 - €7,000 = €34,250
• Income tax at 10-15%: €3,400-5,100
• Total: ~€10,000-12,000 = 18-22% effective

Significantly below maximum rate because social security often capped and income tax is flat in many European countries.

If income exceeds ~€40K/year, corporate structure often more efficient.

Money Flow

1. Clients pay US LLC
2. US LLC transfers money to Mercury/Relay account
3. From there transfers to local corporation (as "service fee", "license fee", or another matching contractual basis)
4. Local corp declares these as revenue, pays corporate tax on profit
5. You withdraw net dividends after tax

Key Points

• Transfer pricing — prices between US LLC and local corp must be "at arm's length." Too-low prices = potential issue. Too-high = excessive home tax. Typically local corp retains 10-20% margin.
• US LLC income above local corp — US LLC keeps 10-20% of income for operations; this money does NOT go to local corp automatically. You need clear US expense policy to justify it.
• Form 5472 reports all transfers — every transfer from US LLC to local corp is reportable transaction. Details in 5472 article.

When NOT Worth Corporate Structure

• Under €30K/year revenue — corporate admin costs ~€2-3K/year (accounting, filings, registrations). Doesn't justify economically.
• If planning to leave home country (digital nomad) — unnecessary complication
• If frequent structure changes — corporate is stable setup for long-term

1. Not declaring because "it's an American company" — most common mistake. Inevitable on home audit.
2. Declaring as dividend instead of active income — effectively using lower dividend rate. IRS audit could find this, home authority too.
3. Declaring only money you withdrew to home account — income declared for year US LLC received it, not when you withdrew. Cash-basis is strictly for US personal, not home declaration.
4. Not filing foreign-income section because no US tax paid — this section isn't about US tax data, but declaration of income as such. Always filled.
5. Currency conversion errors — USD to home currency should be at official rate on income receipt date, not annual average.
6. Ignoring social security — if self-employed and declared income, social security is automatic obligation. Missing = interest + penalties.
7. Year mixing — US tax year and home tax year are usually same (calendar), but receipt dates can straddle years in December-January.

Tax authorities have access to international banking data through Common Reporting Standard (CRS) and automatic information exchange. US hasn't signed CRS directly, but:

• Mercury, Relay, and all US banks must know beneficial owner — in their KYC files
• European banks (Wise, Revolut) where money flows to home — in CRS system
• Large international transfers (over €15K) flag automatically for AML review

If authority finds undeclared income:

• Typical lookback: 5 years
• Taxes + interest + penalties
• Potentially criminal prosecution at large amounts

Good strategy: declare correctly from first year. Cost of perfect compliance is 5-10x less than audit costs.
