Interactive Brokers for your LLC: setup, tax treatment and when to use

8BEN-E. IB does open accounts for non-resident-owned LLCs with W-8BEN-E. Tradovate for futures, Kraken for crypto. Real tax framework (0% US capital gains, treaty rates on dividends), profiles where it fits and how Exentax designs the investing operation.

Without a filed W-8BEN-E, Interactive Brokers withholds 30% on every US dividend paid to a non-resident-owned LLC; with a clean W-8BEN-E, the treatment drops as per treaty.

One of the most frequent questions Exentax clients close on: "Can I open Interactive Brokers in the name of my LLC to invest from the United States?". The answer is yes, it's done, and properly structured it makes sense. In this article we explain how it actually works, which brokers are available to a non-resident-owned LLC, what changes on the tax side, and how to design clean investment operations from your LLC.

The starting point

A US Single-Member LLC, owned by a non-resident, has full legal capacity in the United States. It has an EIN, an operational bank account, a legal address through a registered agent. To open a brokerage account it works exactly like any other US entity: it presents its corporate documents, identifies the beneficial owner with a W-8BEN-E, and operates normally.

A non-resident opening a brokerage account for their LLC is standard operations. What matters is knowing which broker, with what documentation, and for what objective.

Brokers that open accounts for a non-resident-owned LLC

There are real options. The idea that "no top-tier broker accepts a foreign-owned LLC" is false. These are the effective routes:

Interactive Brokers (stocks, ETFs, options, bonds)

IB accepts accounts in the name of a US LLC with a non-resident beneficial owner. The opening is processed as a business account and the key documents are:

Articles of Organization of the LLC.
EIN Letter (CP575 or 147C).
Operating Agreement.
W-8BEN-E signed by the LLC declaring the real beneficial owner.
Identity document of the owner.
Proof of address of the owner.

The process usually takes 2–4 weeks if the documentation arrives complete and consistent. What we see at Exentax: when the LLC is properly formed and the documents are consistent (same legal name, same EIN, same beneficial owner declared in BOI and in W-8BEN-E), the opening is straightforward.

Access: 150+ markets, competitive commissions, professional tools (TWS, IBKR Pro), margin, options, futures via the platform itself.

Tradovate (futures)

Tradovate allows opening accounts in the name of an LLC to trade futures (ES, NQ, CL, GC, etc.). Similar documentation (Articles, EIN, Operating Agreement, W-8BEN-E). It's the reference option when the LLC's activity is futures trading on an intraday or swing horizon.

Kraken (institutional crypto)

Kraken accepts corporate accounts for LLCs and works with non-residents. The institutional/Pro account allows trading crypto assets with regulated custody and serious trading tools. For an LLC with crypto activity (trading, treasury in stablecoins, exposure to BTC/ETH), Kraken is one of the clean routes.

Others available depending on the profile

Charles Schwab International: accounts for non-residents, traditionally more focused on individuals.
TastyTrade / Tradier: accept US LLCs, especially useful for options.
Webull: works with an LLC with standard documentation.

The real criterion is not "which broker will let me in", it's "which broker fits your activity and how your LLC is designed".

What changes on the tax side when you invest through an LLC

Here is the real framework, no marketing and no alarmism.

In the US (federal)

A foreign-owned disregarded SMLLC investing in US financial markets:

Capital gains on US stocks: for non-residents, capital gains from selling US stocks are not US-source income (IRC §865(a)(2)) unless physical presence exceeds 183 days. There is no US tax on portfolio capital gains. This holds when operations run through a disregarded SMLLC.
US dividends: 30% withholding by default, reducible by treaty (15% Spain, 15% Mexico, 15% Colombia, 10% Chile, 15% Argentina). The broker applies the treaty rate if the W-8BEN-E is on file.
Portfolio interest (US bonds): 0% under the portfolio interest exemption (§871(h)) when the requirements are met.
US bank interest: typically exempt for non-residents (§871(i)).

The LLC adds no new federal taxation. What it adds is a clean operating entity with its own brokerage account, its own reporting, its own traceability.

In your country of residence

The dividends and capital gains the LLC receives, when attributed to or distributed to the resident member, are taxed under the rules of your country (IRPF in Spain, IR in Portugal, ISR in Mexico, etc.). Here the LLC is not a tax shield against your local tax authority: the planning comes from the design of the flow (when you distribute, what you reinvest, which vehicles you choose), not from the wrapper.

When it makes sense to invest through an LLC (the real cases)

1. You have an operational LLC with surplus treasury

Your LLC bills, operates, and accumulates cash between distributions. Investing that cash in T-Bills (via Slash or IB), money market or conservative ETFs inside the LLC itself keeps the capital productive without taking it out to your personal life prematurely. Standard, clean operations.

2. You want to trade derivatives (options, futures) with a dedicated vehicle

A brokerage account inside the LLC separates the derivatives activity from your personal estate. If the operation is serious, the LLC brings accounting order, asset separation and a defined tax perimeter. IB for options, Tradovate for futures.

3. Crypto trading at scale

Operating crypto from an LLC opens access to institutional products (Kraken Pro, custody, fees), separates the risk from your personal estate and allows clean traceability for your tax return. For serious volumes it's the standard path.

4. Coordinated family / wealth structure

Families that coordinate their market exposure inside an LLC to keep a single management center, control distributions to members and plan coherently with other structures (a company in the country of residence, a trust, etc.).

5. Active investing with deductible costs

The LLC allows you to deduct operational expenses associated with serious investing activity: data feeds, analysis software, training, infrastructure. When there's real activity, those costs reduce the base.

The one nuance to plan: US estate tax on direct US assets

This is the point worth knowing, without alarmism:

A non-resident who passes away holding US-situs assets above USD 60,000 (direct US stocks, for example) is subject to US federal estate tax. A disregarded SMLLC does not isolate that risk by itself, because it is also looked through for estate tax purposes.

Does this mean you shouldn't invest through an LLC? No. It means that, if your direct US portfolio crosses that threshold, it's worth planning along one of these routes:

Irish/Luxembourg UCITS ETFs inside the LLC: not US-situs, eliminate the estate-tax risk on that portion.
Interposed structure (a non-US company on top of the LLC) when the amounts justify it.
Specific cover (US term life insurance) in specific profiles.

It's standard estate planning, not a problem of the LLC. We design it with you when the invested wealth calls for it.

What we see every week at Exentax

The client about to open IB without a coherent EIN setup: the LLC was formed months ago, the EIN is there, but the operating agreement doesn't mention the beneficial owner correctly and the W-8BEN-E the client prepares has errors. IB asks for clarifications and the process gets stuck. We solve it in one pass: consistent documents, correct W-8BEN-E, clean opening.

The client trading futures from their personal account: when the volume rises, mixing with their personal estate complicates their home-country taxation and the separation. We move it to Tradovate over the LLC, with capitalization documentation and an updated operating agreement.

The client who wants to combine crypto + US stocks + treasury: we design the full stack. Mercury for operations, Slash for treasury in T-Bills, IB for stocks/ETFs, Kraken for crypto. Planned distributions. Continuous US compliance.

How it's done well

Before opening a broker: check that the LLC has coherent corporate documentation (Articles, EIN, Operating Agreement, BOI filed).
Correct W-8BEN-E: identification of the beneficial owner, treaty claim if applicable, dates and signatures in order.
Documented capitalization: the LLC has its own funds to invest; the member's contributions are recorded.
Segregated account: the brokerage account is operated from the LLC's bank account, not from the member's personal account.
Coherent Operating Agreement: reflects the investing activity if applicable, defines how movements are approved, how the result is distributed.
Internal reporting: at every fiscal close, the broker P&L is incorporated into the LLC's accounting and into the 5472 / 1120 pro forma.
Coordination with your local advisor: so the attribution / distribution of investing income is properly declared in your country.

Why Exentax

Because we set up LLCs that are ready to operate with brokers from day one. Consistent documentation, correct EIN, BOI filed, adapted operating agreement, W-8BEN-E prepared. When you go to open IB, Tradovate or Kraken, you won't run into a "come back tomorrow": you'll open the account and trade.

And, above all, we set up the full ecosystem for you: operational banking, treasury with yield, corporate cards, brokers tailored to your objective, planned distributions. A structure that invests with order, not an LLC with an improvised broker bolted on top.

Tax compliance in your country: CFC, controlled-foreign rules and income attribution

A US LLC is a fully legal, internationally recognized vehicle. But compliance does not end at incorporation: as an owner who is tax-resident elsewhere, your local tax authority still has the right to tax what the LLC earns. The key is under which regime.

By jurisdiction

Spain (LIRPF/LIS). An operative single-member disregarded LLC (real services, no significant passive income) is generally treated under income attribution (art. 87 LIRPF): the LLC's net profits are attributed to the member in the year they arise and integrated into the general IRPF base. If instead the LLC elects corporation treatment (Form 8832) and is controlled by a Spanish resident with mostly passive income, the CFC regime (art. 91 LIRPF for individuals, art. 100 LIS for companies) can apply. The choice is not optional: it depends on economic substance, not on the label.
Information returns. US bank accounts with average or year-end balance >€50,000: Form 720 (Law 5/2022 after CJEU C-788/19, 27/01/2022, penalties now under the general LGT regime). Related-party transactions and dividend repatriation: Form 232. US-custodied crypto: Form 721. Relax: at Exentax this is what we do every week, we close it before the letter ever lands in your inbox.
Spain–US tax treaty. The treaty (BOE 22/12/1990, Protocol in force 27/11/2019) governs double taxation on dividends, interest and royalties. An LLC without a permanent establishment in Spain does not by itself create a PE for the member, but effective management can if all activity is run from Spanish territory.
Mexico, Colombia, Argentina and other LATAM jurisdictions. Each has its own CFC regime (Mexico: Refipres; Argentina: foreign passive income; Chile: art. 41 G LIR). Common principle: profits retained inside the LLC are deemed received by the member if the entity is treated as transparent or controlled.

How to read the LLC + Interactive Brokers configuration as a stable operational mapping rather than as an opportunistic combination

The LLC + Interactive Brokers configuration reads more usefully when it's treated as a stable operational mapping between the holder of the brokerage account, the country of residence of the beneficial owner and the type of activity hosted in the LLC, than as an opportunistic combination. The mapping doesn't change with the market direction.

A short note in the LLC folder that records the holder of the brokerage account, the date the account was opened and the activity hosted in the LLC turns the configuration into something the member can review in a few minutes whenever a tax adviser asks for clarification.

Before going further, put numbers on your case: the Exentax calculator compares, in under 2 minutes, your current tax bill with what you would carry running a US LLC properly declared in your country of residence.

> Free consultation, no strings attached

Practical rule: an operative LLC with substance, properly declared in your country of residence, is legitimate tax planning. An LLC used to hide income, fake non-residence or shift passive income with no economic justification falls within art. 15 LGT (anti-abuse) or, worse, art. 16 LGT (simulation). The facts decide, not the paperwork.

At Exentax we structure the entity to fit the first scenario and document every step so your local return can be defended in case of review.

Banking and tax facts worth clarifying

Fintech and CRS information evolves; here is the current state:

Notes by provider

Mercury operates with several federally chartered partner banks and FDIC coverage via sweep network: mainly Choice Financial Group and Evolve Bank & Trust, with Column N.A. still in some legacy accounts. Mercury is not itself a bank; it is a fintech platform backed by those partner banks. If Mercury closes an account, the balance is typically returned by paper check mailed to the account holder's registered address, which can be a serious operational problem for non-residents; keep a secondary account (Relay, Wise Business, etc.) as contingency.
Wise ships two clearly different products: Wise Personal and Wise Business. For an LLC you must open Wise Business, not the personal account. Important CRS nuance: a Wise Business held by a US LLC sits outside CRS because the account holder is a US entity and the US is not a CRS participant; the USD side operates via Wise US Inc. (FATCA perimeter, not CRS). In contrast, a Wise Personal opened by an individual tax-resident in Spain or another CRS jurisdiction does trigger CRS reporting via Wise Europe SA (Belgium) on that individual. Opening Wise for your LLC does not bring you into CRS through the LLC; a separate Wise Personal in your own name as a CRS-resident individual does report.
Wallester (Estonia) is a European financial entity with an EMI/issuing-bank licence. Its European IBAN accounts are within the Common Reporting Standard (CRS) and therefore trigger automatic reporting to the tax administration of the holder's country of residence.
Payoneer operates through European entities (Payoneer Europe Ltd, Ireland) that are also in scope for CRS for clients resident in participating jurisdictions.
Revolut Business: when paired with a US LLC, it operates under Revolut Technologies Inc. with Lead Bank as its US banking partner. The account delivered is a US account (routing + account number); no European IBAN is issued to a US LLC. The European IBANs (Lithuanian, Belgian) belong to Revolut Bank UAB and are issued to European clients of the group. If you are offered a European IBAN tied to your LLC, confirm exactly which legal entity holds that account and which regime it reports under.
Zero tax: no LLC structure delivers "zero tax" if you live in a country with CFC/tax transparency or income attribution rules. What you achieve is no double taxation and correct reporting at residence, not elimination.

Legal & procedural facts

FinCEN and IRS reporting requirements moved recently; the current state is:

BOI / Corporate Transparency Act: your LLC is NOT required to file (a competitive advantage). After FinCEN's March 2025 interim final rule, the BOI Report obligation was narrowed to "foreign reporting companies" (entities formed OUTSIDE the US and registered to do business in a state). A US-formed LLC owned by a non-resident does NOT file the BOI Report: one fewer filing on your calendar, less paperwork, and a cleaner structure than ever. If your LLC was formed before March 2025 and you already filed BOI, keep the acknowledgement. The regulatory status can change again: we monitor FinCEN.gov on every filing and, if the obligation comes back, we handle it at no extra cost. Current status verifiable at fincen.gov/boi.
Form 5472 + pro-forma 1120. For a Single-Member LLC owned by a non-resident, the final regulations of Treas. Reg. §1.6038A-1 (in force since 2017) treat the LLC as a corporation for 5472 purposes. Procedure: pro-forma Form 1120 (header only: name, address, EIN, tax year) with Form 5472 attached. It is filed by certified mail or fax to the IRS Service Center in Ogden, Utah, not e-filed via standard MeF. Due date: April 15; extension via Form 7004 to October 15. Penalty: $25,000 per form per year, plus $25,000 per additional 30 days of non-filing after IRS notice.
Substantive Form 1120. Only applies if the LLC has filed a check-the-box election to C-Corp (Form 8832): it then pays 21 % federal corporate tax and files a substantive 1120. A standard disregarded LLC does not file a substantive 1120 and does not pay federal corporate tax.
EIN and notice. Without an EIN you cannot file 5472 or BOI. The IRS does not warn before imposing penalties; you find out when an EIN is flagged or a later filing is rejected.

LLC + Interactive Brokers: how to invest in US stocks as an entity and why it sometimes makes sense

Investing in US stocks through your LLC rather than personally changes the tax regime, traceability and succession planning. Not for everyone, but for specific profiles (capital >250k, sustained reinvestment plan, residence with favourable CFC) it is technically correct. Here is what to understand before opening.

How the setup works. Single-member LLC (Wyoming preferred for privacy), EIN, IBKR Pro account opened in the LLC's name with W-8BEN-E (treaty benefits if Spain, France, Germany, etc.). IBKR is the broker that best accepts foreign entities and disregarded LLCs; others (Schwab, Fidelity) usually reject non-resident LLCs.
Capital gains and dividend taxation. US stock capital gains for an LLC owned by a non-resident: 0% federal (not effectively connected, no ETBUS). US dividends: 30% withholding default, reduced to 15% (or 0% in specific cases) under treaty with W-8BEN-E. Residence taxation: attribution if LLC disregarded (Spain IRPF; France IR), or dividend if opaque (LATAM).
Why invest from LLC vs personal. Centralisation for professional management, simplified succession (transfer of membership interest vs inheritance of dispersed assets), operational separation from main activity, possible intermediate holding with reinvestment without distribution. NOT an automatic tax shield: tax authority attributes anyway.
When it does not fit. Capital <250k EUR (operational and accounting costs - monthly bookkeeping, annual 1120/5472 - eat the return), residence with aggressive CFC (Spain applies transparency rules, no real saving), or plan to withdraw all in 1-2 years (immediate taxation, useless deferral).

What we are asked the most

Does IBKR let me open as LLC without ITIN? Yes, with the LLC's EIN and a correctly filled W-8BEN-E. ITIN is for the individual owner; rarely required by IBKR for disregarded entity accounts.

Tax difference LLC vs personal for US stocks? In US taxation: virtually none (both non-resident, both 0% capital gains, both 15% dividend under treaty). At residence (Spain): the LLC is attributed, so you are taxed the same. LLC advantage is planning, not direct taxation.

At Exentax we set up LLC + IBKR + W-8BEN-E + investment-specific bookkeeping and model upfront whether it pays off with your capital and residence - to avoid adding complexity without saving.

What if HMRC, the IRS or my local tax authority asks about my LLC?

It's the question every client raises in the first consultation, and the short answer is: your LLC isn't opaque, and a properly declared structure closes any inquiry in standard forms. Your tax authority can request the state Certificate of Formation (Wyoming, Delaware or New Mexico), the EIN issued by the IRS, the signed Operating Agreement, the Mercury or Wise statements for the year, the Form 5472 plus pro-forma 1120 you filed, and the bookkeeping that reconciles income, expenses and movements. If all of that exists and is delivered in order, the inquiry doesn't escalate.

What tax authorities do pursue, and rightly, is sham ownership (nominees, paper residency) and undeclared foreign accounts. A well-structured LLC is the opposite: you appear as beneficial owner in the BOI Report when applicable (verifiable at fincen.gov/boi), you sign the bank accounts and you declare the income where you actually live. The structure is registered with the state Secretary of State, with the IRS and, when European banks are involved, inside the CRS perimeter of the OECD standard.

The mistake that really sinks an inquiry isn't having an LLC; it's not attributing the income correctly in your domestic return, not declaring foreign accounts when the year-end balance exceeds the local threshold (€50,000 in Spain via Modelo 720; the equivalent FBAR / Form 8938 in the US for residents; T1135 in Canada), and not documenting related-party transactions between the member and the LLC. Those three fronts are worth closing before any request arrives, not after.

## What an LLC does NOT do

- It does not exempt you from tax in your country of residence. If you live in Spain, France, Germany or Portugal, you are taxed there on worldwide income. The LLC organises your US side (zero federal tax for non-resident SMLLC pass-through, absent Effectively Connected Income); it does not switch off your domestic taxation. The income tax is computed on the attributed profit, not on the dividends actually paid.

- It is not an offshore vehicle or a BEPS scheme. It is a US entity recognised by the IRS, registered in a specific state with physical address, registered agent and annual informational filings. Classic offshore jurisdictions (BVI, Belize, Seychelles) leave no public trace; an LLC leaves a trace in five different places.

- It does not protect you if you commingle funds. The pierce the corporate veil doctrine kicks in as soon as a judge sees the LLC and the member behaving as the same wallet: mixed accounts, personal expenses paid from the LLC, no signed Operating Agreement, no bookkeeping. Three suspicious transactions are enough.

- It does not save you social security contributions at home. If you are self-employed in Spain, France or Germany, your monthly social contribution remains identical. The LLC handles the trading side with international clients; your personal contribution is independent.

- It does not exempt you from declaring foreign accounts. Spain residents file Modelo 720 / 721; UK residents, the SA106; Portugal residents, the Anexo J of Modelo 3 IRS; Germany residents, the Anlage AUS. Those obligations belong to the individual, not to the LLC.

At Exentax we cover those five fronts every year alongside the US federal calendar (Form 5472, pro-forma 1120, FBAR, state Annual Report and BOI Report when applicable). The goal is that no inquiry finds a loose end and that the structure withstands a 5-to-7-year retroactive review.
