Your tax residency, not your company’s jurisdiction, decides what you pay. Everything else in this business (which state, which free zone, which entity type) sits downstream of that one fact. This guide covers how residency actually works, the four systems (five, once you separate the remittance basis from territorial taxation, as I do in the tax systems of the world) in the world, what authorities really test, and how to change it in a way that survives being looked at.
The rule that actually governs this: company residency and personal residency are separate questions. Forming an entity abroad does not move you, and no structure fixes an unresolved residency: it just adds a second unresolved question on top of the first.
The thing almost everyone misreads
The mistake is not subtle, and it is extremely common: people treat “where my company is registered” and “where I am taxed” as the same sentence.
They are not connected in the way the marketing implies. A US LLC is a state-level entity. Registering one in Wyoming tells you where the entity exists; it tells you nothing about where its owner is taxed. For a single owner, the US generally looks straight through the entity (that is what “disregarded” means) and the profit lands on the owner. The owner is tax resident somewhere, and that somewhere applies its own rules.
So the sequence that works is: settle where you are tax resident, understand how that country treats a foreign entity and its profit, and only then choose the structure. The sequence that fails is the reverse, and it is the one sold at checkout.
The four tax systems
Which system you are in determines what any structure can and cannot do for you. To see it in numbers, the US LLC tax calculator by residence applies each country’s system to the same profit and ranks them on a ladder.
Worldwide. The country taxes its residents on all income, wherever earned. Most of Europe and most of Latin America work this way, along with Portugal and Cyprus. A foreign entity’s profit is generally taxable here, and CFC rules may reach even undistributed profit.
Territorial. The country taxes only locally-sourced income. Panama, Paraguay, Georgia, Costa Rica and Malaysia are commonly cited examples. This is where a foreign structure can genuinely change the outcome, but “foreign-source” is a legal test about where the work happens and where the income arises, not about which entity issues the invoice. Georgia is a good illustration: consulting work performed physically in Tbilisi is Georgian-source income regardless of whether a US LLC invoices for it.
No personal income tax. The UAE, Monaco and a handful of others do not tax individual income at all. This is the cleanest position available and it requires you to actually live there. Note that no personal income tax is not the same as no corporate tax: the UAE has had a corporate tax regime since 2023.
Citizenship-based. Only two countries tax on citizenship rather than residency: the United States and Eritrea. For a US person, moving abroad does not end the filing obligation, and nothing on this site is written for that situation.
Not sure how this applies to your case?
Eleven questions and we tell you whether the LLC fits, and if it does not, that too.
What authorities actually test
The 183-day rule is the one everybody knows and the one that misleads most, because it is rarely the only test.
Most systems apply some combination of:
- Days present, counted over a calendar year or a rolling twelve months.
- Permanent home available to you: a property you own or rent and can use, whether or not you are in it.
- Centre of vital interests: where your family lives, where your economic life is, where your ties are strongest.
- Habitual abode, looked at across several years rather than one.
- Nationality, as a tie-breaker in some treaties.
Two consequences follow. First, you can be under 183 days somewhere and still be treated as resident there. Second, two countries can each conclude you are resident, at which point a double tax treaty’s tie-breaker rules decide, if a treaty exists.
How you actually change it
Changing tax residency is an administrative process with evidence attached, not a decision you announce.
- Leave properly. Deregister where required, file whatever exit formalities exist, and understand any exit tax or quarantine rule. Several countries apply extended rules to people moving to jurisdictions they consider low-tax.
- Arrive properly. Register locally, obtain the residence permit if one is needed, open local accounts, and establish the ties that make the new country your genuine centre.
- Get the certificate. A certificate of tax residency from the new country is the document that makes the position defensible.
- Close the loose ends. Update tax residency self-certifications with your banks and brokers, update your tax forms with platforms that pay you, and make sure the answer is the same everywhere.
- Then structure. Once the above is real, the entity question becomes answerable, and that is what where to set up your company is for.
The step people skip is the third one, and it is the one that matters when someone asks two years later.
Where a US LLC fits, and where it does not
It fits as operating infrastructure: USD invoicing and banking, payment processor access, vendor onboarding with US clients, and a liability layer between the business and your personal assets. Those benefits are real and they are independent of your residency.
It does not fit as a way to change where you are taxed. If you live in a worldwide-income country, the profit is taxed there. If you live in a territorial one, what matters is where the income arises, not which entity invoices. If you have not settled where you live at all, the entity is premature: see a US LLC for digital nomads for what that failure looks like in practice.
The six destinations we deal with most each have a page, written with what does not work about them included: Dubai, Portugal, Cyprus, Paraguay, Panama and Georgia.
One limit stated openly rather than discovered later: the tax depth behind this guide is Spain and Latin America, because that is where we do the modelling ourselves. For the destinations above we work from the local rules and name what needs confirming with a local adviser. If you are tax resident in the United Kingdom, the Netherlands or Australia, we form and maintain the entity end to end, but the local tax read comes from a licensed adviser in your own jurisdiction coordinated alongside us, not from us pretending to know HMRC as well as we know the AEAT.
The assessment starts with residency for exactly this reason, and tells you plainly when the honest answer is to resolve that first and structure later.

Frequently asked questions
Is the 183-day rule all that matters?
No, and building a plan on it alone is the most common way people get caught out. Days present is the most visible test and often the first one applied, but most countries stack additional tests behind it: where your permanent home is, where your centre of vital or economic interests sits, where your spouse and children live, sometimes habitual abode over several years. It is entirely possible to spend fewer than 183 days in a country and still be treated as tax resident there because everything else about your life points at it. Treat 183 days as necessary-but-not-sufficient, in both directions.
Can I be tax resident nowhere?
As a lifestyle description, yes. As a status a tax authority accepts, effectively no. Many countries take the position that you remain resident until you demonstrate residency somewhere else, and several have deemed-residency or exit rules written precisely for people who leave without arriving. There is also a practical layer: banks, brokers and payment processors ask for a tax residency and a taxpayer identification number as routine compliance, and answering that question inconsistently across institutions is how accounts get frozen pending review.
What is a certificate of tax residency, and do I need one?
It is a document issued by a tax authority stating that you are tax resident there for a given period, and it is the piece of evidence that turns "I live in X now" into something defensible. You typically need it to claim treaty benefits, to satisfy a former country of residence that you genuinely left, and increasingly to satisfy banks. If your plan for changing residency does not include obtaining one, the plan has a hole in it.
Does forming a US LLC change my tax residency?
No, and this is the single most expensive misunderstanding in this field. Company residency and personal residency are separate questions with separate rules. Forming an entity in another country does not move you, does not end your obligations where you live, and does not create a treaty position for you personally. A single-member LLC is transparent for US federal purposes, which means its profit flows to you, and "you" are tax resident somewhere.
What are CFC rules and do they apply to me?
Controlled foreign company rules let a country tax the profits of a foreign entity you control, even when those profits have not been distributed to you. They typically require a control threshold (often 25% or more, counting related parties) and a comparison between the entity effective tax rate and what the domestic rate would have been. Many worldwide-income countries have them. A single-member entity owned outright by one resident, sitting at or near zero foreign tax, is a plausible candidate for the test.
Whether CFC rules reach a specific structure depends on your country of residence, the ownership percentage and the entity effective rate, and needs confirming with a local tax adviser before you rely on any general description, including this one.
Should I resolve residency before or after forming the company?
Before, in almost every case. Every meaningful question about the entity is answered by your residency: how its profit is characterised, whether CFC rules bite, what you disclose and to whom, whether a treaty helps. Forming first means committing to a structure before you know the rules it will be judged under, and in the worst version you end up with a structure built around the country you were leaving.
