A Wyoming LLC is one of the cleaner structures a non-resident can use to hold a US stock portfolio. It gives you a US legal entity with an EIN, a name a broker can underwrite, and Wyoming's charging-order protection over the membership interest, while keeping you out of US state income tax and franchise tax. What it does not do is rewrite the federal tax rules: a non-resident still pays US tax only on the narrow categories the Internal Revenue Code reaches, and for a passive portfolio those rules are surprisingly favorable on gains and surprisingly blunt on dividends. This guide walks through how the structure actually works, which brokers realistically open accounts, how each type of investment income is taxed and reported, and the mistakes that quietly cost people money or trigger penalties.
What the LLC actually changes, and what it does not
The first thing to be clear about is that a single-member Wyoming LLC owned by one non-resident is, by default, a disregarded entity for US federal income tax. The IRS looks straight through it to you. That means the brokerage account is legally the LLC's, but the dividends, interest, and gains are treated as if you earned them personally. Holding US stocks through the LLC does not, by itself, lower your US tax bill compared with holding them in your own name as a non-resident. The dividend withholding rate is the same, and the capital-gains treatment is the same.
So why use the entity at all? Three reasons that are about structure, not tax. First, liability separation: the portfolio sits in a distinct legal person, walled off from your other ventures and your personal exposure. Second, flexibility: an LLC lets you add members later, layer in a holding company, or assign the membership interest, without retitling every brokerage position. Third, Wyoming's charging-order protection under Wyoming Statutes Section 17-29-503, which extends even to single-member LLCs and limits what a creditor of the owner can reach to a charging order against distributions rather than seizing the underlying assets.
It is also worth stating plainly what Wyoming gives you on the entity-cost side. Wyoming imposes no state income tax and no franchise tax. The only recurring state obligation is the annual report license tax, with a minimum around $60, calculated on assets the LLC has situated or employed in Wyoming. A brokerage account custodied outside Wyoming is generally not a Wyoming-situated asset, so most pure investing LLCs sit at or near the minimum. You also must keep a registered agent in the state year-round.
Disregarded vs. multi-member: the entity choice that drives your filings
The number of owners changes your federal filing track entirely, so decide this before you open anything. A single-member, foreign-owned LLC is a disregarded entity. It files no income tax return of its own, but it must file Form 5472 attached to a pro forma Form 1120 every year to report related-party transactions, with the return due April 15 and extendable to October 15 via Form 7004. The penalty for missing or botching Form 5472 is $25,000 under IRC Section 6038A, which is why this filing matters even when there is no tax due.
A multi-member, foreign-owned LLC is treated as a partnership. It files Form 1065 with a Schedule K-1 for each member, due March 15. If the portfolio's activity ever rises to a US trade or business and produces effectively connected income, the partnership must withhold under Section 1446 and file Form 8805, and each foreign partner files a Form 1040-NR. For a genuinely passive investment club among a few non-residents this is heavier paperwork than a single-member structure, so many solo investors deliberately keep the LLC single-member to stay on the disregarded track.
The table below summarizes the practical differences.
| Feature | Single-member (disregarded) | Multi-member (partnership) |
|---|---|---|
| Federal income return | Pro forma 1120 + Form 5472 | Form 1065 + K-1s |
| Filing deadline | April 15 (ext. Oct 15) | March 15 (ext. Sep 15) |
| Owner-level filing | Usually only if you have other US income | 1040-NR if ECI/withholding |
| Key penalty exposure | $25,000 (Form 5472) | Partnership + withholding penalties |
| Charging-order protection | Yes (Wyo. Stat. 17-29-503) | Yes |
How dividends are taxed: FDAP and the 30% default
US-source dividends paid by US corporations are FDAP income, which stands for fixed, determinable, annual, or periodical income. FDAP is taxed at a flat 30% rate, collected by withholding at the source. The broker withholds before the money ever reaches the account; you do not get a bill, you get a smaller credit. This is the single most important number for a US-stock portfolio because, unlike capital gains, dividends are taxed at source every single year regardless of whether you sell anything.
The 30% rate is the default, and it is reduced only by a tax treaty in force between the US and the owner's country of residence. Many treaties cut the portfolio-dividend rate to 15%, but you cannot assume that figure applies to you. Rates vary by country and by the size of the holding, and some countries have no US treaty at all, in which case 30% stands. The reduced rate is not automatic either: it only takes effect once a valid Form W-8BEN-E is on file with the broker and the treaty article is correctly claimed in Part III. If that form is missing, stale, or filled in wrong, the broker defaults to 30%.
A few nuances are worth flagging so you do not over-promise yourself a low rate. The often-cited 0% dividend rate applies only in narrow situations, such as certain pension funds or a corporate shareholder holding a large equity stake, not an ordinary individual investor's portfolio. And the residency claimed on the W-8BEN-E must be real and supportable; treaty benefits hinge on you being a resident of the treaty country under that treaty's terms. If you are unsure of your country's rate, treat 30% as the working assumption and have a US CPA confirm the treaty article before relying on anything lower.
Why capital gains are usually not US-taxed
Here is the asymmetry that makes US investing attractive for non-residents: capital gains on US stocks are generally not subject to US tax for a non-resident who is not engaged in a US trade or business and who is not present in the United States for 183 days or more during the year. There is normally no withholding on sale proceeds, and no US tax return is triggered by the gain itself. A non-resident can buy Apple, hold it for five years, sell at a large profit, and owe the US nothing on that appreciation.
The reason is in how the Code sources each kind of income. Dividends from US corporations are explicitly US-source FDAP and get caught in the withholding net. Gains from selling stock by a non-resident, by contrast, are generally not treated as US-source taxable income unless one of the specific triggers applies. The two main triggers to keep off are the 183-day physical-presence rule for the calendar year and engaging in a US trade or business such that the gains become effectively connected. For a buy-and-hold investor living abroad, neither applies.
This shapes strategy in a concrete way. A growth-oriented or accumulation portfolio that compounds through price appreciation faces very little US tax, because the return arrives as gains rather than dividends. A high-yield, dividend-heavy portfolio gives up 15 to 30 cents of every dividend dollar to US withholding before it ever reaches you. None of this removes home-country tax: your country of residence almost certainly taxes your worldwide income, so it can tax both the dividends and the gains, often with a credit for the US tax already withheld.
Interest, Treasuries, and other income types
US-source interest deserves its own note because it behaves differently from dividends. Interest is also FDAP with a 30% default, but a large slice of it is exempt. The portfolio interest exemption removes US tax on most interest paid on registered debt to non-residents, and many treaties reduce or zero out interest withholding as well. In practice, interest on US Treasury securities held by a non-resident is frequently subject to no US withholding. So a portfolio leaning on Treasuries or qualifying bonds can generate income that escapes the 30% bite that hits stock dividends.
A few other categories round out the picture for a typical brokerage account:
- Foreign dividends (a non-US company you hold through the US broker) are foreign-source and not US-taxed, though they may carry their own foreign withholding from the issuer's country.
- Capital gains distributions from US mutual funds and ETFs can be reclassified in ways that affect withholding; fund structures sometimes pass through items that are treated as dividends. Read the fund's tax characterization rather than assuming all distributions are gains.
- Substitute payments from securities lending can be recharacterized as dividend-equivalent and withheld at the dividend rate, which catches some margin-account holders off guard.
The clean mental model is: dividends and most stock-fund distributions are exposed to 30%/treaty withholding, qualifying interest is often exempt, and price-appreciation gains are generally free of US tax. Build the portfolio knowing which bucket each holding's return falls into.
Brokerage options and the realistic odds of approval
The hard truth of non-resident-owned LLC investing is that brokerage access is narrower than for operating businesses or US persons. Interactive Brokers is the primary, reliable choice: it opens business accounts for non-resident-owned LLCs, has genuinely global onboarding, low fees, and broad market access. Most readers will end up here. A handful of other brokers accept LLCs with heavier KYC and country restrictions, and several mainstream apps simply do not take LLC accounts at all.
| Broker | Non-resident-owned LLC |
|---|---|
| Interactive Brokers | Primary option; global onboarding, low fees, broad markets |
| TastyTrade | Accepts some LLCs; limited country coverage |
| Charles Schwab | Tightened review for non-resident-owned LLCs |
| Fidelity | Limited acceptance |
| E*TRADE | Limited acceptance |
| Robinhood | Does not accept LLC accounts |
Approval is the broker's decision and is never guaranteed. It depends on your country profile, the documents you supply, and the broker's current policy, all of which change. Some countries are restricted or prohibited outright, so check the broker's live list before you form anything. Funding the brokerage usually runs through a US business account at a fintech such as Mercury, Relay, or Wise; remember these are fintechs operating on FDIC-insured partner banks, not chartered banks themselves, and their approval is likewise a separate hurdle that depends on your country and paperwork.
Step-by-step: opening and running the account
The sequence below is the path most non-resident investors follow. Do them in order, because each step depends on the one before it.
- Form the Wyoming LLC and appoint a registered agent. The entity exists in roughly 24 hours; you do not need to visit the US, hold a visa, or have a US address.
- Obtain the EIN. Without an SSN, you apply on Form SS-4, typically by fax, and receive the number in about 8 to 10 business days. Every broker and bank will require it.
- Open a US business account at a fintech like Mercury, Relay, or Wise to receive and route funds. Approval is provider-dependent.
- Apply for the brokerage business account in the LLC's name with the EIN, most likely at Interactive Brokers.
- File Form W-8BEN-E with the broker to certify foreign status and claim any treaty rate on dividends in Part III. Without it, withholding defaults to 30%.
- Fund the account from the business bank account, keeping a clear record of each contribution.
- Track every buy, sell, dividend, and withholding through the year, and keep the broker's year-end tax statements for filing.
- File the annual federal forms (pro forma 1120 + Form 5472 for a single-member LLC), the Wyoming annual report, and renew the registered agent.
Worked example: the cost of a missing W-8BEN-E
Suppose the LLC holds US shares that pay $10,000 of dividends in a year, and the owner is a resident of a country whose treaty sets the portfolio-dividend rate at 15%. The outcome depends entirely on whether the paperwork is in place.
- No valid W-8BEN-E on file: the broker withholds the 30% default, so $3,000 is taken at source and $7,000 reaches the account.
- Valid W-8BEN-E claiming the treaty: withholding drops to 15%, so $1,500 is taken and $8,500 reaches the account.
That is a $1,500 swing on the same dividends, every year, for the sake of one correctly completed form. Now suppose the investor also sells appreciated stock during the year for a $40,000 gain. Assuming they are not present in the US for 183+ days and not engaged in a US trade or business, that gain is generally not US-taxed, and no withholding hits the proceeds. The LLC still reports the related-party capital contributions used to fund the account on Form 5472. This is an illustration only; treaty eligibility and rates are country-specific, so confirm yours with a US CPA before relying on a number.
The day-trading and ECI edge case
The favorable capital-gains treatment rests on the investor being passive and abroad. The edge case that breaks it is active trading conducted from inside the United States, which can support an argument that you are engaged in a US trade or business. If that argument succeeds, the gains become effectively connected income, taxed on a net basis at graduated rates rather than escaping US tax, and the whole calculus changes. Physical presence of 183 days or more in the year is a separate trigger that can pull gains into US tax even for an otherwise passive holder.
The line here is genuinely fact-specific. Most non-resident investors who trade from their home country, even fairly actively, take the position that their activity is investing rather than a US trade or business, and that gains remain non-ECI. But high-frequency trading, trading while physically in the US, or a pattern that looks like a business operation can move you across the line. If you trade heavily or spend meaningful time in the US, do not guess; have a US CPA evaluate your specific facts before you assume the gains are tax-free.
Common mistakes that cost money or trigger penalties
A handful of errors come up repeatedly, and all are avoidable.
- Skipping or fumbling Form 5472. It is easy to think a disregarded LLC with no US tax due has nothing to file. It does: the pro forma 1120 plus Form 5472, with a $25,000 penalty under Section 6038A for getting it wrong. Capital contributions used to fund the brokerage are exactly the related-party transactions this form exists to capture.
- Letting the W-8BEN-E lapse or assuming a treaty rate you cannot claim. The form expires and must be refreshed; an expired form reverts you to 30%. Claiming a 15% or 0% rate you are not entitled to is worse than claiming nothing.
- Forgetting home-country tax. US treatment is only half the story. Your country of residence typically taxes worldwide income and may tax both dividends and gains, usually crediting the US tax withheld. Plan for both jurisdictions.
- Confusing fintechs with banks. Mercury, Relay, and Wise are fintechs on partner banks. Their approval is not guaranteed and some countries are excluded, so verify access before committing to the structure.
- Treating the LLC as a tax shelter. Because the single-member LLC is disregarded, holding stocks through it does not lower your US dividend or gains tax versus holding them personally. Use it for liability separation, structuring flexibility, and Wyoming charging-order protection, not for a federal tax cut that is not there.
A Wyoming LLC gives a non-resident a credible, protected, low-overhead vehicle for a US stock portfolio, with no state income or franchise tax and strong charging-order protection over the interest. If you want the entity, EIN, and registered agent handled in one step so you can move straight to opening the brokerage account, we form a complete Wyoming LLC for $397 all-inclusive, with the LLC live in about 24 hours and the EIN obtained without an SSN.
