There is no income tax treaty between Brazil and the United States, so the starting point for any Brazilian founder running a Wyoming LLC is the default 30% US withholding on US-source FDAP income, with no treaty rate to claim, and a careful look at whether that default even touches your business.
Treaty status and what it means for Brazil founders
Brazil does not have a comprehensive income tax treaty in force with the United States. This is verified against the IRS "United States income tax treaties - A to Z" list: that index runs alphabetically from Armenia through Uzbekistan, and Brazil simply does not appear in it. There is no signed-but-not-yet-in-force income tax treaty waiting on ratification either. Despite decades of intermittent discussion, the two countries have never concluded a bilateral income tax convention. Brazil is one of the only G20 economies in that position.
What the two countries do have is a narrow set of agreements that get confused with a tax treaty but are not one. There is a 2007 Tax Information Exchange Agreement (TIEA), confirmed in a U.S. Department of the Treasury press release; a Social Security Totalization Agreement that entered into force in 2018; and a FATCA intergovernmental agreement for financial-account reporting. None of these reduces US withholding rates, none provides a residency tie-breaker, and none creates a treaty-based foreign tax credit mechanism. They handle information sharing and social security coordination, not income tax relief.
The practical meaning for a Brazil-resident Wyoming LLC owner is direct. Any US-source FDAP income (fixed, determinable, annual, or periodical income such as dividends, royalties, and certain interest) that is attributable to you as a non-resident alien is subject to the statutory 30% gross withholding under Internal Revenue Code sections 1441 and 1442. There is no Article 10 dividend rate, no Article 12 royalty rate, and no reduced interest rate to invoke, because there are no articles. Do not let any provider tell you otherwise, and do not file a W-8BEN-E that claims a Brazil treaty rate, because none exists and claiming one is a false certification.
The good news, covered below, is that for the overwhelming majority of operating LLCs run by Brazilian founders, US-source FDAP income is not actually present, so the 30% default never bites. The treaty absence costs you nothing on operating revenue. It only matters if you deliberately route passive US investment income through the LLC.
Withholding rates by income type
Because there is no treaty, there is no reduced column to populate. The table below shows the default US position for a Brazil-resident owner and is intentionally honest about the fact that there is no relief to claim. The 30% figure is the statutory rate; the "Brazil treaty rate" column does not exist, so it is replaced with the actual status.
| Income type | Default US rate | Brazil status (no treaty) |
|---|---|---|
| US-source dividends (e.g., US stocks held through the LLC) | 30% | No treaty relief — full 30% withheld |
| US-source royalties (software, IP, content licensing) | 30% | No treaty relief — full 30% withheld |
| US-source portfolio interest | 30% statutory | Usually 0% under the domestic portfolio-interest exemption (IRC §871(h)), not a treaty |
| Bank deposit interest from a US bank | 30% statutory | Generally exempt for non-resident aliens under US domestic rules |
| Business/operating profits with no US permanent establishment or ECI | Generally not US-taxed | Not US-taxed regardless of treaty (see next section) |
| Effectively connected income (ECI) from a US trade or business | Graduated US rates (net) | Same with or without a treaty — a treaty would not have helped here |
| Services performed physically outside the US | Not US-source | Not subject to US tax |
Two nuances matter. First, the portfolio-interest exemption and the bank-deposit-interest exemption are domestic US law, available to Brazilian residents even without a treaty — so most interest a Brazilian founder might earn is not actually hit by the 30%. Second, ECI is taxed on a net basis at graduated rates whether or not a treaty exists; the absence of a Brazil treaty does not increase your ECI exposure, it just means you have no Article 7 "business profits" shield to fall back on if the IRS argues you have a US trade or business. Per the IRS guidance on FDAP income, the 30% applies to gross FDAP, while ECI follows separate net-tax rules.
It is also worth being precise about a contrast that confuses many Brazilian founders comparing notes with peers in treaty countries. An Indian or German LLC owner who happens to hold US dividend stocks can file a W-8BEN-E and knock the dividend withholding down to 15% (or lower). A Brazilian owner in the identical situation pays 30%, period. That gap is the only concrete, dollars-and-cents cost of Brazil lacking a treaty — and it applies exclusively to genuine US-source passive income. It does not touch services revenue, and it does not make your operating business taxable in the US. Many "Brazil-US treaty" search results you may have read are written for US expats living in Brazil worried about Brazilian-side tax on their US income; that is the mirror-image problem and its conclusions (claim a US Foreign Tax Credit on Form 1116 instead of treaty relief) do not transfer to a Brazil-resident running a US LLC. Keep the two fact patterns separate.
Does the treaty even matter for your LLC?
For most Brazilian founders, the honest answer is: the missing treaty barely matters, because the income their LLC earns is not US-source FDAP in the first place.
A single-member Wyoming LLC owned by a non-resident is, by default, a disregarded entity for US federal tax purposes. The IRS looks straight through it to you, the foreign owner. The question then becomes whether you are engaged in a US trade or business and whether the income is effectively connected (ECI), or whether you have US-source FDAP. If neither is true, there is no US federal income tax and nothing for a treaty to reduce.
Consider how a typical Brazil-resident LLC actually earns money. You write software, run an agency, freelance, sell digital products, do e-commerce dropshipping, or provide consulting — and you perform all of that work physically from São Paulo, Florianópolis, or wherever you live in Brazil. Under US sourcing rules, income from services is sourced to where the services are performed. Services performed in Brazil produce foreign-source income, not US-source income, even when every client and every dollar is American. Foreign-source income earned by a non-resident with no US permanent establishment is outside the US federal income tax net entirely. This is the core reason hundreds of thousands of non-resident founders run US LLCs without owing US income tax: their income is foreign-source services income, full stop.
So the treaty absence is irrelevant to that revenue. There is no FDAP withholding on your Stripe, Wise, or Mercury payouts because those are business receipts, not dividends, royalties, or interest paid to a non-resident — they are simply your customers paying for services. Payment processors are not withholding agents on your sales proceeds. (Separately, platforms may issue an information return: under the One Big Beautiful Bill Act, signed July 4, 2025, the Form 1099-K threshold reverted to more than $20,000 AND more than 200 transactions per the IRS 1099-K FAQ update. A 1099-K is informational; it does not by itself create US tax.)
The treaty only starts to matter if you deliberately introduce US-source FDAP into the LLC — for example, parking the LLC's cash in US dividend-paying stocks or ETFs, or licensing IP to a US payer who treats it as a royalty. Then the 30% bites with no relief, and you would have been better off holding those investments elsewhere. The planning lesson is structural, not treaty-based: keep US passive investment income out of the disregarded LLC, and the lack of a Brazil treaty has no cost. Where a treaty country owner might shrug off a 15% dividend rate, a Brazilian owner pays the full 30%, so the avoidance discipline is simply more important here.
The one scenario where you genuinely want professional review is if your facts start to look like a US trade or business — US-based employees, a US office, US-based dependent agents concluding contracts, or US inventory and fulfillment you control. Those facts can create ECI, and without a treaty there is no Article 7 business-profits defense. Most digital founders never get close to that line. Using a US registered agent, a US business bank account (Mercury, Wise), and US payment processors does not, on its own, create a US trade or business — those are administrative facts, not the conduct of business through a US fixed place or US-based people. The line is about where the income-producing work physically happens and who performs it, and for a solo founder in Brazil that work happens in Brazil.
How to claim: W-8BEN-E line-by-line + Form 8833 if needed
Even though there is no treaty rate to claim, your US payers (Stripe, Mercury, marketplaces, SaaS platforms, US clients) will still ask for a withholding certificate to document your foreign status and switch off backup withholding. For a non-resident-owned single-member LLC that is a disregarded entity, the correct form is Form W-8BEN-E, completed in the LLC's name. (Note: a disregarded entity normally does not file its own W-8 because the US looks to the owner — but in practice payers onboard the LLC, so you complete W-8BEN-E identifying the LLC and its foreign owner. Follow each payer's onboarding flow. The IRS Instructions for Form W-8BEN-E govern.)
Line-by-line for a Brazil-resident, no-treaty filing:
- Line 1 — Name of organization: your LLC's exact legal name as on the Wyoming Articles of Organization.
- Line 2 — Country of incorporation: United States.
- Line 3 — Disregarded entity name, if different: usually blank for a single-member LLC.
- Line 4 — Chapter 3 status: check Disregarded entity (single-member LLC owned by a non-resident individual). Do not check Corporation.
- Line 5 — Chapter 4 (FATCA) status: for a non-financial operating business, check Active NFFE (Active Non-Financial Foreign Entity) and complete the corresponding Part XXV certification, or the status that genuinely fits your facts.
- Line 6 — Permanent residence address: your real home address in Brazil. Not a US address, not a registered-agent address.
- Line 8 — US TIN: your LLC's EIN exactly as shown on the IRS CP-575 letter.
- Line 9b — Foreign TIN: your Brazilian CPF (or CNPJ if applicable).
- Part III (Claim of Tax Treaty Benefits) — Leave this blank. Brazil has no income tax treaty with the US, so there is no country and no article to enter. Filling in Part III would be a false certification.
- Part XXV (if you selected Active NFFE) — sign the active-NFFE certification.
- Part XXX — sign and date; the signer certifies authority to act for the entity.
Submit the form to each payer, not to the IRS. A W-8BEN-E is generally valid through the end of the third calendar year after signing, then must be renewed (and re-submitted earlier if any information, such as your address, changes).
Form 8833 (Treaty-Based Return Position Disclosure) is not applicable to you, because you are not taking any treaty-based position — there is no Brazil treaty to base a position on. Do not file Form 8833 in a misguided attempt to reduce withholding; it does nothing here and there is no position to disclose. Form 8833 is only for taxpayers who are claiming a treaty benefit (e.g., an India or UK resident invoking Article 7), and even then only above certain thresholds. The correct posture for a Brazilian founder is: foreign-source operating income that is simply outside US tax, documented by a clean W-8BEN-E with Part III blank.
Form 5472 + pro-forma 1120 obligation ($25k penalty) regardless of treaty
The treaty question is completely separate from your annual US filing obligation, and the filing obligation does not go away just because you owe no US tax. A single-member US LLC owned by a non-resident and treated as a disregarded entity is a reporting corporation for these purposes and must file Form 5472 ("Information Return of a 25% Foreign-Owned U.S. Corporation") attached to a pro-forma Form 1120 every year there is a reportable transaction. Reportable transactions include essentially all money flowing between you and the LLC: your capital contributions, owner draws, loans, and payments. Forming the LLC and funding its bank account is itself a reportable transaction, so a first-year filing is almost always required.
The penalty for failing to file, filing late, or filing a substantially incomplete Form 5472 is $25,000 per form under IRC section 6038A, and it can recur for continued non-compliance after IRS notice. This penalty applies whether or not Brazil has a treaty, whether or not your business made a profit, and whether or not you owe a single dollar of US tax. It is purely an information return. The deadline tracks the corporate calendar — generally April 15 for a calendar-year filer, with a six-month extension available via Form 7004. The pro-forma 1120 is filled out only with the top identifying information; the substance lives in the 5472. The IRS overview of Form 5472 and the section 6038A rules confirm the requirement and the penalty. Treat this as the one non-negotiable US filing for every Brazilian-owned Wyoming LLC.
Common mistakes
- Claiming a treaty rate that does not exist. Filling in Part III of W-8BEN-E with "Brazil" and an article number is a false certification. There is no Brazil-US income tax treaty. Leave Part III blank.
- Routing US dividend stocks or ETFs through the disregarded LLC. With no treaty, US-source dividends are withheld at the full 30% with no relief. Hold US passive investments outside the operating LLC, or expect to lose 30% of dividend income.
- Filing Form 8833. There is no treaty-based position to disclose, so Form 8833 is the wrong form and does nothing for a Brazilian founder.
- Skipping Form 5472 + pro-forma 1120. The single most expensive mistake — a flat $25,000 penalty under IRC §6038A, owed even when there is zero US tax. Forming and funding the LLC triggers the first filing.
- Citing the wrong Brazilian law for offshore taxation. Brazilian-resident individuals who control a foreign company are now taxed under Lei 14.754/2023, effective January 1, 2024 — a flat 15% annual tax on the offshore company's net profits each December 31, declared in your DIRPF, even if nothing is distributed (see Mayer Brown's analysis of Law 14.754/23). The older corporate CFC regime under Lei 12.973/2014 is not the rule that governs an individual founder's Wyoming LLC. Get a Brazilian contador to apply the 14.754/2023 regime correctly.
- Confusing DBE with DCBE. The Brazilian Central Bank filing is the Declaração de Capitais Brasileiros no Exterior (CBE/DCBE), mandatory annually for residents whose foreign assets reach US$1,000,000 at year-end, per the Banco Central do Brasil CBE rules. Late or missing filings draw fines from R$25,000 to R$250,000.
- Assuming a treaty is coming. There is no ratification timeline. Plan around the current no-treaty reality, not a hypothetical future agreement.
- Confusing W-8BEN with W-8BEN-E. The individual form is W-8BEN; the LLC uses W-8BEN-E.
Wyoming LLC formation through wyomingllc.xyz is $397 all-inclusive (the Wyoming Secretary of State filing fee is included; see the Wyoming Secretary of State business division for the state-level record), and an ITIN, if you later need one for a personal US filing, is a separate $297 add-on. None of those services change the treaty analysis above: there is no Brazil-US income tax treaty, the 30% default applies to any US-source FDAP you allow into the LLC, and the Form 5472 obligation stands every year regardless.
