A US LLC for Swiss residents: your tax liability ends at the border

Swiss tax law treats your US LLC in its own way: in two places clearly in your favour, and in one place more idiosyncratically than you may like. This page sorts out all three.

The two pieces of good news first. First: your tax liability ends when you leave. The law says so in as many words: tax liability ends "when the taxpayer leaves Switzerland" (Art. 8 para. 2 DBG, the Federal Direct Tax Act). No provision anywhere in the DBG attaches to your former residence, your citizenship or a period after departure. Second: capital gains on movable private assets are tax-free (Art. 16 para. 3 DBG), and where an increase in value is never taxed, there is nothing to settle when you leave either. There is no general exit tax on private shareholdings.

The idiosyncratic part: how Switzerland classifies your LLC is the least harmonised question of the whole subject. More on that in a moment, because that is exactly where your numbers are decided.

Consultations are held in English only.

The short version:

• After you leave, only economic allegiance remains: businesses, permanent establishments and real estate in Switzerland, board fees, pension benefits (Art. 4 and 5 DBG). No trailing liability, no time limit.
• The classification of the LLC is officially unresolved: the cantonal coordination line (SSK 2011) leans towards treating it like a Swiss limited liability company, while the Federal Supreme Court treated a Wyoming LLC as a partnership in 2015. It comes down to your Operating Agreement and the US tax treatment.
• If you live in Switzerland, the LLC shields nothing: either it becomes taxable in Switzerland itself through its effective management, or its results are attributed to you as self-employment income, AHV included.
• The DBG has no CFC rules. Switzerland does not need them: effective management, transparency and look-through in cases of tax avoidance are enough.
• When you leave, there is nothing to settle on private assets. The one trap is called business assets.

What remains after you leave

Under Art. 4 and 5 DBG, Switzerland only stays on board if you leave something behind: a business or permanent establishment in Switzerland, Swiss real estate, board fees from Swiss companies, claims secured by real estate, benefits from Swiss occupational pension schemes. It is an exhaustive list with a clear logic: what is taxed is what is in Switzerland, not who you used to be.

The only provision in the DBG that attaches to nationality at all concerns federal employees abroad. For emigrants with an LLC, it is irrelevant. You deregister, and the matter is closed.

The classification question: SSK versus the Federal Supreme Court

The law treats foreign entities like the domestic legal entities they most closely resemble "legally or in fact" (Art. 49 para. 3 DBG). It sounds simple, and it is not, because the two authoritative voices in Swiss practice pull in different directions:

The Swiss Tax Conference (SSK), practice notes of 2011: As a rule, the LLC is to be treated like a Swiss limited liability company. Legal personality, limited liability, formation by registration: "there are therefore hardly any conceivable cases in which the LLC is to be treated as a partnership under domestic law". The consequences of this reading: distributions are investment income, partially taxed from a 10% shareholding; the LLC's own profits are disregarded for the Swiss member as long as they are not distributed; the shares count at market value for wealth tax.

The Federal Supreme Court, judgment 2C_894/2013 of 18 September 2015: A Wyoming LLC was assessed using an expressly "pragmatic mix of methods", in which the tax treatment in the US counts as a "decisive element". The result in that specific case: a partnership. What decided it was the Operating Agreement (capital accounts, no share capital, profit allocation in proportion to the interests) and the undisputed transparency in the US. The consequence: the holding is self-employment, the interests are business assets, payments from the LLC are taxable, and a tax-free private capital gain is ruled out. Worth noting in passing: the Federal Tax Administration (ESTV) had already quietly deleted the old equation "LLC interest = limited liability company share" from its circular back in 2009.

The honest answer: there is no formulaic answer, and any page that sells you "Switzerland always treats the LLC as X" is wrong. The classification depends on how your Operating Agreement is actually drafted (share capital or not, capital accounts, profit mechanics, transferability) and on the US tax treatment (transparent by default, or a check-the-box election as a corporation). These are exactly the levers we set at formation, depending on which outcome is right for your case. A leading decision that settles the question generally is still missing; the SSK itself said as much about its own practice in 2011.

The honest fork in the road: an LLC while living in Switzerland

The sentence we read out to every prospective client applies to you too: while you live in your home country, the US LLC is not a tax-saving model. Switzerland needs no CFC rules for this; it has three simpler tools:

Tool 1: effective management. Legal entities have unlimited tax liability in Switzerland if their effective management is in Switzerland (Art. 50 DBG). The SSK says so expressly for the LLC: if it is run from Switzerland, it is taxed like a Swiss limited liability company. The mailbox in Wyoming changes nothing if the decisions are made at your kitchen table in Zug.

Tool 2: transparent attribution. If your LLC qualifies as a partnership under the Federal Supreme Court's line, its results are attributed to you on an ongoing basis as self-employment income (Art. 18 DBG). On top of that comes something many people forget: the AHV (Swiss old-age and survivors' insurance). Partners in associations of persons without legal personality that pursue a gainful purpose owe contributions on their share of the profit (Art. 20 para. 3 AHVV, the AHV Ordinance), and according to case law this applies regardless of whether you personally work in the business (BGE 141 V 234). At present that is 10.0% AHV/IV/EO on income from self-employment, with no upper limit (AHV leaflet 2.02, as at 1 January 2026). So the profits of your transparent LLC attract not only income tax but social security contributions as well.

Tool 3: look-through in cases of tax avoidance. For constructions that exist only on paper, the tax offices need no special provision; look-through is established practice.

What the DBG genuinely does not have is CFC taxation that attributes the undistributed profits of a genuine foreign company to you. On the SSK track, retained LLC profits therefore remain untaxed, but only as long as the LLC has neither its effective management nor a permanent establishment in Switzerland, and at the price that distributions are then fully taxable investment income. Anyone selling you the "tax-free accumulating LLC run from your Swiss sofa" is leaving out Tool 1.

The Switzerland-US tax treaty shields nothing

One more illusion we can clear away right now: under the double tax treaty, the transparent LLC is entitled to treaty benefits only to the extent that its income is taxed in the hands of its members (Art. 4 para. 1(d) of the Switzerland-US treaty). On the SSK reading, distributions from an LLC that is transparent in the US are not dividends within the meaning of the treaty, because the US does not treat them like income from shares for tax purposes (Art. 10 para. 4). And the business profits article only helps you if you can prove a genuine US permanent establishment: that is a tax-reducing fact, and the burden of proof is on you. Without a US permanent establishment, the profit share of a member resident in Switzerland ends up in the Swiss tax base, on one track or the other. The Federal Supreme Court has expressly confirmed that this classification logic is consistent with the treaty.

The rule of thumb for practice: the US LLC does not work as a Swiss tax-saving model, but as a vehicle for people who have left. The difference lies not in the LLC, but in where you live.

Three Swiss starting points

You are emigrating and your destination is set. Paraguay, Dubai, Costa Rica, the usual suspects. For you, the LLC is the standard tool: tax-free in the US when structured correctly, respected internationally, with banking worthy of the name. Your calculation is the simplest in all of Europe: no trailing liability, no exit tax on your private portfolio, only the business assets question and your pension decisions. Once your deregistration is complete, your LLC profits belong for tax purposes to your new country of residence, not to Bern.

You are setting off as a nomad. Here too you are in a good position: if your Swiss tax liability ends when you leave, nothing follows you, even without a new tax home. The practical questions remain all the same: if you do not genuinely give up your tax residence, you do not end your tax liability either, and being "resident nowhere" makes neither opening accounts nor treaty protection any easier. The 183-day myth gets told wrongly around Swiss pub tables as well.

You are staying in Switzerland. Then you form the LLC for the US market, liability protection, banking, or as a vehicle prepared for a later move abroad, and you form it with your eyes open: on either of the two tracks it is taxed in Switzerland, and on the transparent one with AHV on top. What you can spare yourself is the illusion; what often still pays off are the structural advantages. Whether your case belongs on the limited-liability-company-style or the transparent design is the most important question before formation, not after it.

The clean route: leaving Switzerland plus an LLC

For Swiss residents the route is pleasantly short, because there is no trailing liability and no exit tax on private assets. Here is the map of what still needs settling:

• End your tax liability cleanly. Tax liability ends when you leave (Art. 8 para. 2 DBG); in the year you leave, tax is assessed only up to the cut-off date. The condition is that you have genuinely given up your residence: deregistration, home, centre of your life.
• Check the business assets trap. Capital gains on private assets are tax-free, but transferring business assets to foreign operations counts as a disposal (Art. 18 para. 2 DBG). What makes this sensitive is, of all things, the Federal Supreme Court's line: if your LLC interest has qualified as a business asset, leaving can trigger a settlement on the hidden reserves. Anyone taking a sole proprietorship or partnership interests with them faces this anyway.
• Decide on AHV and your pension fund. Leaving ends your coverage, and the questions of a vested benefits account, a cash withdrawal and voluntary insurance come up.

After that, the simplest rule of the whole subject applies: your new country of residence decides what happens to the LLC profits. Switzerland is out, from day one.

What we take on for our Swiss clients

Mount Bonnell Advisors in Austin has looked after Swiss clients for years, from the Zurich SaaS founder to the emigrant moving to Paraguay. We handle the entire US side:

• Formation in the right state (all 50 compared), with Registered Agent, formation documents and privacy protection through our firm's address
• Operating Agreement drafting with the Swiss classification in mind: share capital mechanics, capital accounts, transferability, depending on whether your case needs the limited-liability-company-style or the transparent design
• US tax number (EIN; your personal ITIN with the Credit Builder) and ongoing compliance: annual reports, state fees, Form 5472, beneficial ownership monitoring
• Banking: US business accounts and payment providers, and if you wish, building US credit with the Credit Builder
• Contracts: the template library drafted by attorneys

What we do not replace: your tax representation in Switzerland. The cantonal tax office's assessment of your individual case, your tax return and any ruling you obtain with a Swiss fiduciary (Treuhänder) or tax expert. We provide the US structure and the documentation that this work builds on.

How the formation works

The US side is a craft, and it is ours (with honest timelines):

1. Choose your state. Wyoming for anonymity and asset protection, New Mexico for lean long-term running, Florida for a US presence with a beach. The comparison of all 50 saves you the research.
2. Order, questionnaire, name check. Done in half an hour, after which we file.
3. An Operating Agreement made to Swiss measure. Capital accounts or share capital mechanics, profit allocation, transferability: we build the structure that fits the outcome you are aiming for and document it so that your fiduciary and the tax office can work with it.
4. EIN, account, credit. We obtain the US tax number from the IRS, then support your account and payment provider setup and, if you wish, building your US credit with the Credit Builder.
5. Hand the compliance calendar to us. Annual report, Registered Agent, Form 5472: from now on, deadlines are our problem.

The questions our Swiss clients ask most

Do I have to declare the LLC to the tax office while I live in Switzerland? Your worldwide income and worldwide assets belong in your tax return, and so does your LLC interest. How it is valued and taxed depends on the classification, which is exactly why clean documentation from day one pays off.

Can I choose the classification? Not choose, but shape it: the Operating Agreement and the US classification are the levers that the SSK and the Federal Supreme Court themselves name as decisive. Anyone who ignores this at formation and has to argue the point later holds the weaker cards.

Does the LLC pay tax in the US? Structured correctly, no: no US permanent establishment, no ETBUS business (effectively connected trade or business in the US), and it is then a transparent exempt LLC. You still need to understand the permanent establishment logic, because it works in both directions.

What does it all cost? One price, one package, ongoing support from the firm included: the price list by state.

Your next step

If your move is set or you already live abroad, formation is the easy part: see prices, order, and we take over. If you are still in Switzerland and want to know which track your case lands on, or what the Operating Agreement must look like so that it lands on the right one, the consultation with Sebastian, held in English, is the place to start: one hour, honest feedback, a 15-minute guarantee.
