Double Taxation Treaties: What Expats in Argentina Need to Know

When I filed my first Argentine tax return in 2020, I nearly had a panic attack. I was looking at paying income tax in Argentina AND the United States, with no treaty between the two countries to sort it out. Seven years later, I have figured out how this works — but it took an Argentine contador, a US tax preparer, and a lot of late nights reading IRS publications.

If you are an expat living in Argentina, understanding double taxation is not optional. It is the difference between legal tax efficiency and either overpaying or accidentally committing tax fraud.

Argentina's Treaty Network

Argentina has signed double taxation treaties (formally called Convenios para Evitar la Doble Imposición) with about 20 countries. Here are the ones that matter most to expats:

Countries WITH a Treaty:

United Kingdom — comprehensive treaty, in force since 1997
Spain — comprehensive treaty, updated protocol
Germany — comprehensive treaty
France — comprehensive treaty
Italy — comprehensive treaty
Australia — comprehensive treaty
Canada — comprehensive treaty
Brazil — comprehensive treaty (important for Mercosur business)
Chile — comprehensive treaty
Belgium, Denmark, Finland, Netherlands, Norway, Sweden, Switzerland — all have active treaties
Russia — treaty exists

Countries WITHOUT a Treaty:

The United States has NO double taxation treaty with Argentina. This is the single most important tax fact for American expats here.

United States — NO treaty. Negotiations have stalled repeatedly over decades.
Mexico — NO treaty
Colombia — NO treaty
Japan — NO treaty (though one has been discussed)
Most of Southeast Asia, Africa, and the Middle East — NO treaties

The absence of a US-Argentina treaty means American citizens and green card holders face the most complex tax situation of any expat group in Argentina.

Tax Residency: The 183-Day Rule

Argentina considers you a tax resident if you spend more than 183 days in the country during a calendar year (January 1 - December 31). Once you become a tax resident, you are taxed on your worldwide income — not just Argentine-source income.

Key details:

The 183-day count includes partial days
Temporary absences (vacations, business trips) generally do not break your residency status once established
You can also become a tax resident by "establishing the center of your vital interests" in Argentina, even if you spend fewer than 183 days — this is subjective and based on family ties, economic connections, and habitual abode
Tax residency is different from immigration residency. You can be a tax resident without having a DNI, and you can have a DNI without being a tax resident (if you spend most of the year abroad)

My situation: I crossed the 183-day threshold in my first year (2019). Since then, I have been filing as an Argentine tax resident. Even though I still have US filing obligations, Argentina is my primary tax jurisdiction.

ARCA: Argentina's Tax Authority

In late 2024, AFIP (Administración Federal de Ingresos Públicos) was restructured and rebranded as ARCA (Agencia de Recaudación y Control Aduanero) under the Milei administration. The functions are essentially the same — they collect income tax, VAT, social contributions, and customs duties.

Everything you used to do through the AFIP portal now goes through ARCA. The website is arca.gob.ar and you log in with your CUIT/CUIL number and clave fiscal (tax password).

What ARCA Expects from You:

If you are a tax resident with income above the minimum threshold, you must:

1. Register as a taxpayer (either Monotributo or Régimen General) 2. File annual income tax returns (Impuesto a las Ganancias) — usually due in June for the previous year 3. File Bienes Personales (wealth tax declaration) if your assets exceed the threshold 4. Pay monthly or quarterly advance payments depending on your tax category

Monotributo vs. Responsable Inscripto

These are the two main tax regimes for individuals in Argentina:

Monotributo (Simplified Regime)

Who it is for: Small businesses, freelancers, and sole proprietors earning below a threshold (the categories range from A to K, with the highest allowing gross income up to roughly ARS 68 million annually as of 2026 — approximately $55,000 USD)
How it works: You pay a single fixed monthly fee that covers income tax, social security (jubilación), and health insurance (obra social). The fee ranges from about ARS 30,000 to ARS 500,000/month depending on your category.
Pros: Simple, predictable, low administrative burden. You do not need to track expenses or file complex returns.
Cons: You cannot deduct expenses, you face invoicing limits, and some clients (especially larger companies) prefer working with Responsable Inscriptos.

Responsable Inscripto (General Regime)

Who it is for: Higher earners, companies, and professionals whose income exceeds Monotributo limits
How it works: You pay progressive income tax (Ganancias) on net income (income minus deductible expenses), IVA (21% VAT) on your invoicing, and social security contributions.
Pros: You can deduct business expenses, no income cap, more professional credibility.
Cons: Significantly more complex. You need a good contador (accountant). Monthly IVA filings, annual Ganancias filing, advance tax payments.

My recommendation: If you are just starting out or freelancing remotely, Monotributo is almost always the right choice. Switch to Responsable Inscripto only when your income forces you out of Monotributo categories or when the tax math favors it.

Bienes Personales (Wealth Tax)

Argentina has a wealth tax called Bienes Personales that applies to your total assets as of December 31 each year. For 2025/2026:

Threshold: Assets above approximately ARS 100 million (roughly $80,000 USD) are taxable
Rates: Progressive, from 0.5% to 1.75%
Argentine residents are taxed on worldwide assets — your US bank accounts, investments, property in other countries, all count
Non-residents are only taxed on Argentine assets

Special Rules for Foreigners:

Assets held abroad by Argentine tax residents are taxed at a higher rate (called the "differential rate") — up to 2.25% for assets held in non-cooperative jurisdictions
The Milei government has been reducing Bienes Personales rates as part of the RIGI (Régimen de Incentivo para Grandes Inversiones) package, with plans to phase it out by 2027. But for 2026, it still applies.

How to Avoid Double Taxation Without a Treaty (US Citizens)

If you are American, here is how you avoid paying taxes twice:

Foreign Tax Credit (IRS Form 1116)

The most common method. You calculate your Argentine tax liability and claim it as a credit against your US tax liability. Dollar-for-dollar, Argentine taxes paid reduce your US taxes owed.

How it works: You file your Argentine taxes first, then report the taxes paid to the IRS on Form 1116. If you paid $10,000 in Argentine income tax, you get a $10,000 credit against your US tax bill.
Limitation: The credit cannot exceed what you would have owed in US taxes on the same income. Excess credits can be carried forward one year or back ten years.
Why it usually works: Argentine income tax rates (progressive up to 35%) are comparable to US federal rates, so the credit typically covers most or all of your US liability.

Foreign Earned Income Exclusion (FEIE — IRS Form 2555)

You can exclude up to $130,000 (2026 figure, adjusted annually) of foreign earned income from US taxation if you meet either:

Bona fide residence test: You are a bona fide resident of Argentina for an entire tax year
Physical presence test: You are physically present in Argentina for 330 full days during any 12-month period

Important: FEIE only applies to earned income (salary, freelance income). It does NOT cover investment income, rental income, or capital gains. For those, you need the Foreign Tax Credit.

Practical Example:

Say you earn $80,000 freelancing from Argentina:

1. You owe Argentine Ganancias (income tax) of approximately $15,000 2. You claim FEIE on your US return, excluding the full $80,000 from US income 3. US tax owed: $0 (income excluded) 4. Argentine tax owed: $15,000 5. Total tax: $15,000

Alternatively, without FEIE:

1. US tax on $80,000: approximately $12,000 (effective rate) 2. Argentine tax: $15,000 3. Foreign Tax Credit: $12,000 (limited to US liability) 4. US tax owed: $0 (fully offset by credit) 5. Total tax: $15,000

Either way, you end up paying only Argentine taxes. The mechanism differs, but the result is similar. In some cases, FEIE is better (lower Argentine income); in others, FTC is better (higher Argentine income, excess credits to carry forward).

For Citizens of Treaty Countries (UK, Spain, Germany, etc.):

Your life is much simpler. The treaty between your country and Argentina will specify:

Which country has primary taxing rights on different types of income
How to claim relief from double taxation (usually a credit method similar to the US FTC, but codified in the treaty)
Reduced withholding rates on dividends, interest, and royalties

Consult the specific treaty text and a tax advisor familiar with both jurisdictions.

Common Mistakes

Assuming you do not need to file in Argentina because you work remotely for a foreign company. Wrong. If you are a tax resident, all income is reportable.
Not declaring foreign assets for Bienes Personales. ARCA has information-sharing agreements with many countries. They will find out.
Using Monotributo for income that clearly exceeds the limits. ARCA audits this. Penalties include back taxes plus interest plus fines of 50-100%.
Forgetting US state taxes. Some US states continue to tax you even after you leave. California, for example, has aggressive rules about taxing former residents.
Not keeping peso/dollar conversion records. You need to convert all amounts to pesos for Argentine filings and to dollars for US filings. Use the official BNA exchange rate and document everything.

Finding Professional Help

You need at minimum:

An Argentine contador (accountant) who understands expat situations. Budget ARS 50,000-150,000/month for ongoing tax compliance.
A US tax preparer (if American) with expat experience. Many work remotely — firms like Greenback Expat Tax Services, Bright!Tax, or local CPAs with international expertise.
Consider a one-time consultation with an international tax attorney if your situation is complex (significant investments, business ownership in multiple countries, etc.)

The cost of professional help is a fraction of what you would lose from mistakes. This is not an area for DIY.
