Key takeaways
- For US federal tax purposes, a single-member LLC is disregarded by default: its income belongs to its owner.
- A foreign owner with no US trade or business often pays no US federal income tax — but still has filing obligations.
- Your country of residence will usually tax the LLC’s profits as if you had earned them directly.
- In Spain, tax-transparent LLCs have generally been treated as income-attribution entities.
The US Limited Liability Company has become hugely popular among digital entrepreneurs. It is quick to set up, cheap to maintain, opens the door to US banks and payment platforms and, above all, has a reputation for “not paying taxes”.
That last part is where the problem starts. An LLC does not eliminate taxes: in most cases, it simply moves them to your country of residence.
What a US LLC is
An LLC is a company created under the laws of a US state, such as Delaware, Wyoming or New Mexico. Like a corporation, it limits its members’ liability, but its tax treatment is very flexible. For US federal tax purposes:
- Single-member LLC: treated by default as a disregarded entity: the IRS ignores the company and attributes its income to the owner.
- Multi-member LLC: treated by default as a partnership: the income flows through to the members.
- Election: an LLC can choose to be taxed as a corporation by filing Form 8832.
Why many foreign owners pay no US tax
If the owner is not a US tax resident and the LLC has no trade or business effectively connected with the US — no office, employees or dependent agents there — its income is generally not subject to US federal income tax. The US sees that income as the foreign owner’s, earned outside the US.
That is where the “tax-free” idea comes from. But it only describes the US side of the story.
Tax transparency: your country taxes you
Because the LLC is transparent, most countries of residence look through it. If you live in a country that taxes its residents on their worldwide income, the LLC’s profits will usually be taxed there as if you had earned them personally — whether or not you withdraw the money.
Each country classifies foreign entities with its own criteria. Some follow the US treatment and consider the LLC transparent; others compare its legal features with local company types and may treat it as a corporation, which changes how and when the income is taxed.
The case of Spain
The Spanish tax authorities have generally treated tax-transparent US LLCs as entities under the income attribution regime (entidades en régimen de atribución de rentas). In practice, a Spanish resident member must report the LLC’s income in their personal income tax return according to its nature — for example, as business income — taxed at progressive rates.
Setting up an LLC therefore does not reduce the tax bill of a Spanish resident. It can also add complexity: US filings, Spanish reporting obligations for foreign accounts and assets, and possible social security obligations for the activity you carry out.
Common mistakes with LLCs
- Assuming no filings are needed: Form 5472 and state requirements apply even with zero US tax.
- Not declaring the income at home: transparency means the income is yours, even if it stays in the LLC’s account.
- Believing no one will know: information exchange between tax authorities makes undeclared structures increasingly easy to detect.
- Using an LLC to ignore your residency: if you actually live in a country, that country’s rules apply regardless of where your company is.
When an LLC can make sense
An LLC is not a bad tool. It can be useful to sell to US customers, access US banking and payment processors, or as part of an international structure that has been designed and reported correctly in the owner’s country of residence.
The key is to decide based on your actual tax residency — not on what worked for someone else. If you are considering an LLC or already have one, an international tax structuring review will tell you how it is really taxed in your case.
Frequently asked questions
Does a US LLC pay taxes?
A single-member LLC owned by a non-resident with no US trade or business generally pays no US federal income tax, but its owner is usually taxed in their country of residence.
Is an LLC tax-free for Spanish residents?
No. Spain has generally treated transparent LLCs as income-attribution entities, so the member pays Spanish personal income tax on the profits.
What is Form 5472?
An annual information return that foreign-owned single-member LLCs must file, together with a pro forma Form 1120, to report transactions with their owner.
Is a Dubai company a better option than an LLC?
A Dubai company is a separate taxable entity with its own rules. Whether it makes sense depends on where you live and where the company is actually managed.
