US Taxes for Americans in Argentina: FBAR, FEIE, the Treaty and Catching Up (2026 Guide)
Updated: Oct 6
Who this guide is for: Americans in Argentina, and Argentine founders selling to the US
Moving to Argentina does not end your relationship with the IRS. A US citizen or green-card holder files a US return on worldwide income every year, wherever they live, and reports foreign accounts on top of it. Most of the people who call us from Buenos Aires, Córdoba and Mendoza are not trying to avoid that — they simply never heard it, or heard it years after they moved. This guide lays out the US rules that actually apply in Argentina, what the Agencia de Recaudación y Control Aduanero (ARCA, formerly AFIP) side of the picture means for the US return, and how to catch up if you are behind.
I am an Enrolled Agent, licensed by the US Treasury to represent taxpayers before the IRS from anywhere in the world. We work with four groups in Argentina: US citizens and green-card holders living in Buenos Aires, Mendoza or Bariloche — many working remotely for US employers; Argentine-Americans and dual citizens with family, property or an inheritance in Argentina; Americans with Argentine rental property, farmland or a family business interest; Argentine founders, developers and freelancers who want a US LLC, EIN and US bank account to bill American clients. This is general information, not individual advice.
The US-Argentina tax treaty and totalization: what they do and do not do
There is no US-Argentina income tax treaty in force, so there is no treaty tie-break, no treaty pension article and no treaty-sourced relief — double taxation is managed one-sidedly through the US Foreign Tax Credit and Argentina's own rules.
There is no US-Argentina totalization agreement, so self-employed Americans in Argentina can owe US self-employment tax on top of Argentine social contributions on the same income.
The single most common misunderstanding we correct: a treaty never removes the obligation to FILE. It changes how specific income types are taxed, and the saving-clause in every US treaty lets the IRS tax its own citizens as if most of the treaty did not exist.
FBAR, FATCA and the accounts you have in Argentina
FBAR applies to Argentine accounts at Banco de la Nación Argentina, Galicia, Santander Argentina and every other local bank once the combined high balance of all foreign accounts crosses the reporting threshold — and peso-dollar conversions do not change that.
FATCA (Form 8938) is a second, separate report with higher thresholds for people living abroad; missing one and not the other is common and fixable. Both are informational — no tax is due on the form itself — but the penalties for skipping them are the largest in the expat rulebook.
FEIE vs. Foreign Tax Credit in Argentina
The Foreign Earned Income Exclusion covers wages and self-employment income earned while a bona fide resident of Argentina or physically present abroad long enough; it does not cover US-source income, pensions or investment income.
With no treaty, the Foreign Tax Credit is the only relief mechanism — and Argentina's history of currency controls means the peso value of income on the Argentine return and the dollar value on the US return can diverge sharply, which has to be reconciled on the US side at defensible exchange rates.
The choice is not permanent, but revoking the exclusion locks you out of it for several years, so the decision should be modeled against your actual mix of wages, self-employment and investment income before the first return is filed.
Businesses, pensions and investments: the forms that surprise people in Argentina
An Argentine SRL or SA owned by an American can trigger Form 5471; Argentine mutual funds (FCI) are generally PFICs, and an inherited Argentine property brings Form 3520 reporting for the inheritance itself.
Without a totalization agreement, a self-employed American in Argentina owes US self-employment tax on net earnings even while paying into the Argentine system — the FEIE excludes income tax, not self-employment tax.
Every one of these forms carries an automatic, per-form penalty for non-filing that has nothing to do with whether tax was owed — which is why they matter more than the 1040 itself for many long-term residents.
What the Agencia de Recaudación y Control Aduanero (ARCA, formerly AFIP) taxes — and how it interacts with your US return
Argentina taxes residents on worldwide income and has a wealth-type tax on assets that can reach foreign holdings, so an American who becomes Argentine-resident should expect both the IRS and ARCA to want a full worldwide picture.
Argentina's exchange-control history means the practical question of how income enters the country and at what rate it is converted matters as much as the tax rate itself; the current rules change often and must be confirmed before moving money.
We are a US firm: we handle the US side in-house and coordinate with your local accountant on the Argentina side, rather than pretending to be licensed in both.
Argentina-specific patterns we see
Three things come up in Argentina cases more than anywhere else:
Currency controls create the signature Argentina problem: a remote worker paid in dollars may be legally required to convert at an official rate while their US return values the same income differently — the gap is a tax issue, not just an inconvenience.
The Argentine remote-work and tech community is enormous and mostly bills US clients; for an Argentine (non-US) developer, the right structure is usually a US LLC with an EIN and a Form 5472 filing — not a US tax return.
Inherited Argentine property — an apartment in Palermo, a family estancia — arrives with Form 3520 reporting on the inheritance, basis questions when it is sold, and often years of unfiled FBARs on the account the estate paid into.
Behind on US taxes? The streamlined path back
Americans in Argentina who have not filed for years generally qualify for the Streamlined Foreign Offshore Procedures — three years of returns, six years of FBARs, a non-willfulness statement and no failure-to-file penalty — as long as the IRS has not already written to them.
The program is designed for exactly this population, and the non-willfulness statement is the part that needs a professional's attention — it is a signed narrative to the IRS, not a checkbox.
Argentine founders and freelancers: reaching US clients with a US LLC
Not everyone reading this is American. Many of our Argentina clients are Argentine founders, freelancers and agencies who bill US customers and want dollar banking, Stripe and a US invoice. A non-US person can own a US LLC and get an EIN without a Social Security Number; the annual price is a Form 5472 information return and a pro-forma 1120, and the reward is US market access without a US tax return on the owner's worldwide income in most single-owner setups.
The trap is doing it halfway — forming the LLC and skipping the 5472, which carries its own automatic penalty.
Argentina cities we serve

Frequently Asked Questions
Do I have to file US taxes if I live in Argentina?
Yes. US citizens and green-card holders file on worldwide income every year regardless of where they live; the treaty and the FEIE reduce the tax, not the filing duty.
Do my Argentina bank accounts need an FBAR?
FBAR applies to Argentine accounts at Banco de la Nación Argentina, Galicia, Santander Argentina and every other local bank once the combined high balance of all foreign accounts crosses the reporting threshold — and peso-dollar conversions do not change that.
Is there a US-Argentina tax treaty?
There is no US-Argentina income tax treaty in force, so there is no treaty tie-break, no treaty pension article and no treaty-sourced relief — double taxation is managed one-sidedly through the US Foreign Tax Credit and Argentina's own rules.
Does Argentina have a Social Security totalization agreement with the US?
There is no US-Argentina totalization agreement, so self-employed Americans in Argentina can owe US self-employment tax on top of Argentine social contributions on the same income.
I have not filed in years while living in Argentina. What now?
Americans in Argentina who have not filed for years generally qualify for the Streamlined Foreign Offshore Procedures — three years of returns, six years of FBARs, a non-willfulness statement and no failure-to-file penalty — as long as the IRS has not already written to them.
