Argentina-US tax treaty for Delaware LLC founders: 2026 deep dive

Argentina-US tax treaty status

Argentina does not currently have a ratified income tax treaty with the United States. Default withholding rules apply.

Why tax treaty matters for Delaware LLC founders

US tax treaties (formally Double Taxation Agreements, or DTAs) reduce withholding rates on certain US-source income flowing to residents of treaty countries. For Delaware LLC founders based in Argentina, treaty-rate withholding applies to US-source FDAP (fixed, determinable, annual, periodical) income types: royalties, certain interest, dividends, and some service-related payments.

Without a US tax treaty, Argentina residents face the default 30% US withholding on US-source FDAP income. This affects royalty income, certain affiliate payments, AdSense earnings, and similar revenue streams. Form 5472 obligations on the US LLC side are unchanged regardless of treaty status.

How withholding works for Delaware LLC founders in Argentina

US payers (Google AdSense, Amazon Associates, Stripe Connect, royalty platforms) withhold federal tax on US-source FDAP payments to non-US recipients. The withholding rate is:

• Default: 30% of the gross payment, withheld at source.
• Treaty rate: Not applicable; Argentina does not have a US tax treaty.
• To capture treaty rate: File W-8BEN-E with each US payer. The form is per-payer; each platform requires its own filing.

W-8BEN-E filing for Argentina-based LLC owners

W-8BEN-E is the IRS form used by foreign entities (and disregarded-entity LLCs owned by foreign persons) to claim treaty-rate withholding reduction. The key counter-intuitive point: for a single-member US LLC owned by a Argentinaresident treated as a disregarded entity, the entity for treaty purposes is the Argentina-resident owner, not the LLC itself.

Critical fields:

• Part I, Box 4: Chapter 3 entity classification. For a single-member LLC, the foreign owner is the entity for treaty purposes.
• Part I, Box 5: Chapter 4 (FATCA) classification. "Active NFFE" for non-financial entities with substantially less than 50% passive income.
• Part III: Treaty benefits claim. Specify Argentina as treaty country and the article being claimed (typically Article 7 for business profits or Article 12 for royalties).
• Sign and date Part XXX.

Form 5472 applies regardless of treaty status

Tax treaty status does not eliminate the Form 5472 filing obligation. Foreign-owned single-member US LLCs file Form 5472 + pro forma Form 1120 each year regardless of whether the home country has a US tax treaty. Form 5472 is an information return; the treaty affects how the underlying income is taxed, not whether the information return is filed.

Penalty for failure to file Form 5472: $25,000 per occurrence. Treaty residents are not exempt. Engage a CPA familiar with non-resident-owned LLC filings.

Home-country taxation for Argentina residents

Argentine residents are taxed on worldwide income under AFIP rules. The Bienes Personales tax applies to foreign-held assets, including US LLC interests.

Engage an Argentine tax adviser; the tax structure is complex.

The US side of the analysis (federal tax, Form 5472, Delaware franchise tax) is one half. The Argentina side is the other, and the two need to be coordinated. Engage both a US CPA and a Argentina-based tax adviser. Two-adviser coordination prevents double taxation and compliance gaps.

Income types and Argentina treaty treatment

Service revenue (US clients paying for services)

Service revenue from US clients is typically treated as business profits under the treaty's Article 7 (in treaty countries) or as effectively-connected income for US tax purposes. For service work performed entirely fromArgentina, the income may be sourced to Argentina for treaty purposes, with US tax applying only to income attributable to a US permanent establishment. Permanent-establishment analysis is fact-specific.

Royalty income (Amazon KDP, music distribution, content licensing)

Royalty income from US sources is FDAP income subject to withholding. Without a US tax treaty, default 30% withholding applies.W-8BEN-E captures the treaty rate.

AdSense and affiliate revenue

Google AdSense, YouTube monetization, Amazon Associates, ShareASale, and similar US-payer revenue is generally treated as either royalty (for ad-display revenue) or commission income. Default 30% withholding without treaty-rate reduction.

Distributions from the LLC to the Argentina owner

Distributions from a single-member disregarded LLC to its owner are not separately taxable in the US (the IRS treats the LLC as transparent). Distributions are not US-source FDAP income to the foreign owner; they are simply transfers from the owner's LLC to the owner's personal account. Argentina home-country tax may apply to the distribution depending on Argentina tax rules.

Practical tax-compliance pattern for Argentina-based LLC owners

1. Form Delaware LLC; obtain EIN.
2. File W-8BEN-E with each US payer (AdSense, affiliate platforms, etc.) to capture treaty-rate withholding.
3. File BOI report with FinCEN within 90 days of formation.
4. Engage US CPA familiar with non-resident-owned LLCs for annual Form 5472 + pro forma Form 1120 by April 15.
5. Engage Argentina-based tax adviser for Argentina home-country reporting of LLC income and distributions.
6. Pay Delaware $300 franchise tax by June 1 each year.

Does Argentina have an income tax treaty with the United States?

Argentina does not have a ratified income tax treaty with the United States. The two countries have negotiated and discussed agreements over the years, but as of 2026 no comprehensive bilateral income tax treaty is in force between Buenos Aires and Washington. For an Argentine founder who owns a Delaware LLC, this matters because a treaty is the legal instrument that would otherwise reduce certain US tax rates or assign taxing rights between the two governments. Without one, the default provisions of the US Internal Revenue Code apply on their own terms, and there is no treaty mechanism to lower the standard rates or to resolve cases where both countries claim the right to tax the same income.

The practical takeaway is that an Argentine owner should plan around the domestic rules of each country rather than around treaty relief. In many situations this is less alarming than it first sounds, because the most common Delaware LLC setup for a non-resident founder generates little or no US income tax in the first place. The absence of a treaty becomes relevant mainly in narrower situations, such as when a US business pays the founder passive income like certain royalties or interest. Even then, the analysis turns on the type of income involved. The sections below walk through how the US classifies income, why a pass-through LLC often produces no US tax for its foreign owner, and what reporting duties remain regardless of whether a treaty exists. None of this is tax advice, and an Argentine adviser should confirm how each rule applies to a specific founder.

What does "no treaty" actually mean for an Argentine owner?

When people hear that Argentina lacks a US tax treaty, they sometimes assume the worst, picturing double taxation on every dollar the LLC earns. That assumption is usually wrong. The phrase "no treaty" means only that the United States applies its statutory rules without modification and that Argentina applies its own rules without a treaty override. It does not automatically mean a founder pays US income tax on business profits. Whether US tax arises depends on the nature and source of the income, not on the existence of a treaty. For a typical service or software business run remotely from Argentina, the most likely outcome is that profits are not subject to US income tax at all, because they are not connected to a US trade or business and are not US-source passive income.

Where the lack of a treaty does bite is in the category of US-source passive payments. If a US company pays an Argentine-owned LLC certain types of fixed or determinable income, the United States imposes a default 30% withholding tax at the source. A treaty, where one exists, commonly reduces that figure to a lower agreed rate. Because Argentina has no such agreement, the full statutory rate applies to income that falls into that bucket. Understanding which payments fall into the passive category and which do not is therefore the heart of planning for an Argentine founder. The distinction between passive US-source income and business income earned through personal effort drives nearly every practical conclusion on this page.

FDAP income versus effectively connected income: the core distinction

The US tax code sorts the income of a non-resident into two broad families, and the line between them decides almost everything. The first family is FDAP income, which stands for fixed, determinable, annual, or periodical income. FDAP covers passive flows such as dividends, interest, rents, and royalties that a US payer sends to a foreign person. The second family is effectively connected income, often shortened to ECI, which is income connected with the active conduct of a US trade or business. The two families are taxed in completely different ways. FDAP is generally taxed on a gross basis through withholding at the source, while ECI is taxed on a net basis at the regular graduated rates after deductions, much as a US business would be taxed.

This distinction is where a treaty would normally do its work, and where its absence matters for Argentina. A treaty can reduce or eliminate the withholding rate on FDAP income, turning a default 30% charge into a reduced treaty rate or sometimes zero. A treaty generally does not change how ECI is taxed, because ECI represents real business activity that the United States is entitled to tax on a net basis under its domestic law. For an Argentine founder the consequence is straightforward. If the founder receives US-source FDAP, the lack of a treaty means the full statutory withholding applies. If the founder instead earns business profits that are not effectively connected to a US trade or business, there is usually no US income tax to reduce in the first place, so the missing treaty causes no harm.

• FDAP income: passive, US-source, taxed by gross withholding, treaty-reducible where a treaty exists.
• Effectively connected income: active US business income, taxed on a net basis, generally not reduced by treaty.
• Foreign-source business profits: usually outside the US net entirely for a non-resident with no US presence.

Why a pass-through LLC owned by a non-resident often has no US-connected income

A single-member LLC owned by one non-resident individual is by default a disregarded entity for US tax purposes. The Internal Revenue Service looks through the LLC and treats its income as belonging directly to the owner. Because the owner is a non-resident, the question becomes whether that owner is engaged in a US trade or business and whether the income is effectively connected to it. For many Argentine founders, the answer is no. They write software, run an agency, or provide freelance services from Buenos Aires, Cordoba, or Rosario, with no US office, no US employees, and no dependent agent concluding contracts inside the United States. The work is performed in Argentina, and the income is generally treated as foreign-source income that the United States does not tax.

The location of customers usually does not change this conclusion. An Argentine founder can sell to US clients and collect US dollars through Wise, Payoneer, or Mercury without that fact alone creating a US trade or business. What matters is where the income-producing activity happens and whether the founder has a US presence that rises to the level of a trade or business. Selling remotely to American buyers is not the same as operating inside the United States. This is why so many non-resident owned LLCs report no US income tax on their business profits despite substantial US revenue. The structure works as a clean USD billing and banking vehicle, which is especially valuable for Argentine founders protecting earnings against peso volatility, while the actual income tax is owed back home in Argentina rather than to the US Treasury.

The role of Form W-8BEN-E when a US payer is involved

When a US business pays a foreign-owned entity, the US payer has its own legal duty to determine whether to withhold tax. To document the foreign status of the payee and to apply the correct treatment, the payer typically requests a Form W-8BEN-E from the LLC. This form tells the payer that the entity is foreign, identifies the type of entity, and states whether any treaty benefits are claimed. For an Argentine-owned LLC, the form still serves an important purpose even though no treaty exists. It establishes the entity's foreign status and prevents the payer from defaulting to backup withholding rules that apply when no valid documentation is on file. Completing it correctly avoids unnecessary withholding on payments that are not actually subject to US tax.

The treaty-claim section of Form W-8BEN-E is where Argentina's status becomes visible. That part of the form asks the entity to name the country of residence claiming treaty benefits and to specify the article and rate being claimed. An Argentine founder cannot complete that section in the usual way, because there is no Argentina-US treaty to invoke. The founder simply leaves the treaty-benefit claim blank and relies on the underlying nature of the income instead. If the payment is for services performed outside the United States, it is generally foreign-source income and not subject to withholding regardless of any treaty. If the payment is genuinely US-source FDAP, the default 30% withholding applies because no treaty reduces it. Keeping a current, accurate W-8BEN-E on file with each US payer is a practical safeguard either way.

How Argentina taxes the LLC profit

Whatever happens on the US side, an Argentine resident remains taxable in Argentina. Under AFIP rules, Argentine residents are taxed on their worldwide income, which means the profit flowing through a Delaware LLC is reportable and taxable in Argentina even though the entity is formed abroad. Because a single-member LLC is a disregarded entity for US purposes, Argentine tax analysis usually looks through the structure and treats the income as the founder's own, although the precise characterization under Argentine law should be confirmed with a local adviser. The point is that forming a US LLC does not move the income out of the Argentine tax base. The founder's home-country obligations continue, and they are typically the main income tax cost of the whole arrangement.

Argentina also imposes the Bienes Personales tax, a personal assets tax that can apply to foreign-held assets, and a US LLC interest can fall within its reach. This adds a layer that founders from treaty countries with simpler regimes do not always face, and it is one reason the record for Argentina flags the tax structure as complex. Argentine residents should expect to declare the LLC interest, account for the business profit on their personal returns, and consider how Bienes Personales treats the holding. Currency rules administered through the local regulatory framework can also affect how and when US dollars are brought into the country. None of these are reasons to avoid the structure, but they are reasons to plan it with a qualified Argentine professional rather than assuming the US side is the whole picture.

Does a foreign tax credit help an Argentine founder?

A foreign tax credit is a mechanism that prevents the same income from being taxed twice by letting a resident offset home-country tax with tax already paid to another country. For an Argentine founder, the credit only becomes relevant if US tax was actually paid on the income in question. In the common case where the LLC's profits are foreign-source business income with no US income tax due, there is no US tax to credit, so the founder simply pays Argentine tax on the profit and the question never arises. The credit is not a way to reduce Argentine tax on income that the United States never taxed. It only neutralizes genuine double taxation.

Where US tax does arise, such as 30% withholding on US-source FDAP income, an Argentine resident may be able to claim relief for that US tax under Argentine domestic rules, subject to the limits and conditions that local law sets. Because there is no Argentina-US treaty, any such relief comes from Argentina's own unilateral foreign tax credit provisions rather than from a treaty article, and the rules can be narrower or more conditional than treaty-based relief would be. This is one of the clearest places where the absence of a treaty has a real cost, since a treaty often smooths the path to crediting foreign tax. An Argentine adviser can confirm whether and how US withholding can be credited against Argentine liability in a given year.

Form 5472 reporting applies whether or not a treaty exists

One duty that has nothing to do with treaties is the Form 5472 filing requirement. A foreign-owned single-member US LLC that is treated as a disregarded entity must file Form 5472 together with a pro forma Form 1120 each year to report reportable transactions between the LLC and its foreign owner or related parties. These transactions include capital contributions, distributions, loans, and similar dealings. The requirement exists because the United States wants visibility into foreign-owned entities even when they owe no US income tax. The penalty for failing to file, or for filing late or incomplete, is 25,000 US dollars, which makes this one of the most important compliance items for any Argentine founder to track.

It is worth stressing that the Form 5472 obligation is independent of whether the LLC owes any US income tax and independent of Argentina's treaty status. A founder whose business profits are entirely foreign-source and free of US income tax still has to file this information return on time. The form is purely informational, but the penalty for missing it is real and substantial. To file, the LLC needs a US employer identification number, which a non-resident founder can obtain for free by submitting Form SS-4 to the IRS, a process that typically takes around 8 to 10 business days when handled by fax or mail through the international procedure. Building the annual 5472 filing into a calendar from the first year avoids the most common and costly mistake foreign owners make.

What other US filings and costs should an Argentine founder expect?

Beyond Form 5472, a Delaware LLC carries a small set of predictable recurring obligations that an Argentine founder can plan for with confidence. Delaware charges an annual franchise tax of 300 US dollars for an LLC, due each year to keep the entity in good standing. There is no Delaware state income tax on an LLC that does not do business inside Delaware, so for a remote Argentine owner the franchise tax functions as a flat annual maintenance fee rather than a tax on profit. Keeping a registered agent and meeting this annual deadline are the baseline requirements for staying compliant at the state level, and they are simple to budget for.

On the federal side, the main recurring item is the Form 5472 and pro forma 1120 package already described. Whether the founder owes any actual US income tax depends on the income analysis covered above, and for most remote service and software businesses the answer is that no US income tax is due. A useful change for US-formed LLCs is that they are exempt from the beneficial ownership information reporting requirement under the FinCEN interim final rule issued on March 26, 2025, which removed that filing for domestic entities. The headline costs for a typical Argentine founder are therefore modest and foreseeable:

• One-time formation handled for a flat 297 US dollar fee.
• Delaware franchise tax of 300 US dollars each year.
• Annual Form 5472 plus pro forma 1120, with a 25,000 US dollar penalty for failure to file.
• Free EIN via Form SS-4, usually issued in about 8 to 10 business days.
• No US-formed-LLC beneficial ownership filing, per the FinCEN interim final rule of March 26, 2025.

Practical steps for an Argentine founder forming a Delaware LLC

For a founder in Buenos Aires, Cordoba, or Rosario, the practical path is to treat the Delaware LLC as a clean USD billing and banking structure while keeping the real income tax planning anchored in Argentina. The first steps are to form the entity, obtain a free EIN through Form SS-4, and open a USD account with one of the providers that work well for Argentine founders, with Wise and Payoneer being consistently reliable and Mercury improving for software and SaaS businesses. From there, the founder should set up a system to keep records of contributions, distributions, and any related-party transactions, because those are exactly the items the annual Form 5472 reports. Good bookkeeping from day one makes the yearly US filing routine rather than stressful.

Because Argentina has no US treaty and a famously intricate domestic tax and currency environment, the single most valuable step is to engage a qualified Argentine tax adviser early. That adviser can confirm how the LLC profit is reported on the founder's Argentine return, how Bienes Personales treats the LLC interest, and whether any US withholding on US-source income can be credited against Argentine tax. On the US side, the founder should keep a current Form W-8BEN-E on file with each US payer, file Form 5472 and the pro forma 1120 on time every year, and pay the Delaware franchise tax to stay in good standing. Handled this way, the absence of a treaty rarely creates a real problem for a remote service or software business, while the structure delivers the USD stability that makes it so attractive for Argentine founders.
