US Expats in Argentina: Complete Financial Planning Guide (2026)

Argentina hosts a large and growing community of US expats — entrepreneurs, digital nomads, retirees, and long-term residents drawn to Buenos Aires, Mendoza, and Patagonia. The Milei administration's sweeping Ley Bases reforms (2024) dissolved the federal tax agency, restructured the wealth tax, and changed several thresholds — but the fundamental challenges for US citizens remain: no US-Argentina income tax treaty, Ganancias rates from 5–35%, a Bienes Personales wealth tax on worldwide assets, no totalization agreement (full double SE tax for freelancers), and mutual fund PFIC traps that punish anyone who invests locally. Getting any of this wrong is expensive.

1. No US-Argentina Income Tax Treaty: What It Actually Means

The United States and Argentina have no income tax treaty currently in force. A tax convention was signed in 1981 but was never ratified and did not enter into effect. The IRS treaty list does not include Argentina.¹ The practical consequences:

• No tiebreaker clause. If you are simultaneously a tax resident of both the US and Argentina under each country's domestic rules, no treaty article resolves the conflict. You owe income tax in both countries, and relief comes only from the FTC or FEIE.
• No pension deferral articles. Under the US-UK treaty, SIPP contributions grow without annual US taxation. No equivalent exists for Argentine ANSES or private pension products. Gains in those accounts are taxed on the US side as they accrue.
• No reduced withholding rates. Argentine withholding on passive income (dividends, interest) and US withholding on Argentine residents' US-source income apply at standard domestic rates in each country.
• No saving clause to worry about. The saving clause — which preserves each country's right to tax its own citizens regardless of treaty benefits — is a trap in countries like Germany and France. In Argentina, there is no treaty so there is no saving clause. That simplification is offset by the loss of every other treaty protection.

2. Ganancias: Argentine Income Tax and the Milei Reform

Argentina's personal income tax — formally the Impuesto a las Ganancias — applies to Argentine tax residents on their worldwide income. The rate structure is progressive with nine brackets from 5% to 35%. A key post-reform feature: as of 2026, brackets are adjusted semi-annually based on Argentina's Consumer Price Index (IPC) rather than annually, a direct response to persistent inflation.²

As of mid-2026, the top marginal rate of 35% applies to annual taxable income above approximately ARS 60.75 million (the threshold continues to adjust for inflation). At the current exchange rate of roughly ARS 1,150/USD, that equals approximately $52,800/year in USD — meaning most US professionals in Argentina earning in USD-equivalent terms are in or near the top bracket on their Argentine taxable income.

Milei Reforms: Ley Bases (2024) and ARCA

President Milei's omnibus reform package (Ley Bases, 2024) made several structural changes:³

• AFIP dissolved, ARCA created. The federal tax authority AFIP was replaced by ARCA (Agencia de Recaudación y Control Aduanero), with a significantly reduced workforce. Filing mechanics and compliance obligations continue through ARCA.
• Ganancias exemption for salaried workers. A separate reform temporarily exempted the lowest-earning salaried employees from Ganancias. For most US expat professionals, this exemption does not apply — their income levels exceed the threshold.
• Bienes Personales restructured (see Section 7 below).
• Real estate CGT exemption. As of January 1, 2026, gains on real estate transfers by Argentine resident individuals are exempt from Ganancias (see Section 8 below).

ANSES Employee Contributions (Aportes)

Employed workers in Argentina pay mandatory ANSES SIPA contributions (aportes) on their gross salary — currently 11% toward pension, 3% toward social health funds, and additional amounts for other social insurance, totaling approximately 17% employee contribution on gross wages, capped at a monthly ceiling. These contributions are creditable as foreign income taxes for US Form 1116 purposes, potentially increasing the total Argentine tax burden on earned income closer to FTC-covering levels for mid-range earners.⁴

3. FTC vs. FEIE: The Argentina Analysis

The FTC vs. FEIE decision in Argentina is more nuanced than in Germany or France, where rates exceed 50% and FTC clearly dominates. Argentina's 35% top rate means the answer is income-dependent.

When FEIE Typically Wins

For a US citizen earning $90,000–$132,900 as a remote worker or consultant in Argentina, the FEIE ($132,900 ceiling for 2026⁵) can exclude the entire amount from US gross income. Argentina's effective Ganancias rate on this income will run approximately 15–23%, well below the US marginal rate that would apply to the same income. FEIE eliminates US tax on the earned income entirely, while the lower Argentine bill remains. Key constraint: the 5-year revocation lock-in means switching later requires IRS approval and a showing of changed circumstances.

When FTC May Win

For a US citizen earning $200,000+ in Argentina — common for executives in Buenos Aires's financial and technology sectors — Argentine Ganancias at the effective 30–35% rate plus employee ANSES aportes (~17% on wages up to the Argentine SS ceiling) can total significantly. The combined Argentine taxes on earned income often approach or exceed the US federal tax liability, making FTC the more efficient election. FTC also preserves IRA contribution eligibility and does not carry the FEIE's 5-year revocation risk.

The ARS Exchange Rate Complication

Unlike most countries where the FTC calculation is straightforward, Argentina's FTC calculation requires careful attention to exchange rates. If your Argentine employer pays your salary in ARS and you are reporting Ganancias paid in ARS on your US return, the FTC must be translated at the spot rate at the time each tax was accrued or paid. During periods of rapid peso depreciation (Argentina has experienced annual inflation of 50–200%+ in recent years), the USD-equivalent of your Argentine tax bill shrinks dramatically relative to your income. This can reduce the FTC credit available below what you'd expect from the nominal rate percentages. Work with a specialist to model the translation timing correctly.

4. Autónomo and Monotributo for Self-Employed US Expats

Self-employed US citizens in Argentina face a uniquely harsh double-contribution trap because there is no US-Argentina totalization agreement. Both countries' social contributions are owed simultaneously with no mechanism to eliminate either:

• US self-employment tax: 15.3% on net self-employment earnings up to the Social Security wage base ($184,500 in 2026⁵), then 2.9% above. This is owed in full regardless of where the self-employment income is earned.
• Argentine contributions: Depending on income level, either through Monotributo (small taxpayers) or Régimen General / Autónomo (larger earners).

Monotributo (Simplified Regime)

Monotributo bundles Ganancias (income tax), IVA (VAT), and social contributions (pension + social health coverage) into a single monthly flat fee that varies by category. The 2026 income ceiling for Monotributo for service providers is approximately ARS 53.3 million/year (~$46,000 at current rates).³ Monthly fees range from roughly USD 30–$600 depending on category.

FTC trap: Because Monotributo bundles income tax with social contributions and VAT into a single payment, it is not a purely income-based tax. The IRS does not clearly recognize the entire Monotributo payment as an "income tax" for FTC creditability purposes. In practice, many specialists allocate the income-tax portion for FTC and treat the social contribution portion as non-creditable — but the split is uncertain and has not been authoritatively resolved in US guidance. Self-employed US citizens in the Autónomo (Régimen General) pay Ganancias separately and their ANSES aportes are more clearly FTC-creditable as income taxes, but they also pay the highest total Argentine contribution rates.

The Bottom Line for Freelancers and Consultants

A US citizen self-employed in Argentina earning $120,000 may owe: Argentine Monotributo (~$3,600/year bundled), plus US SE tax (~$17,000 on net earnings), plus a residual US income tax above any FTC/FEIE credit. There is no relief mechanism. Argentina is one of the most expensive destinations for self-employed US citizens specifically because of this double-contribution trap. Pre-move entity structuring (S-corp for W-2 salary draw, foreign corporation check-the-box analysis) may reduce SE tax exposure but requires specialist analysis — see our self-employed expat tax guide.

5. ANSES SIPA Pension: No US Treaty Deferral

Argentina's national pension is the ANSES SIPA (Sistema Integrado Previsional Argentino, Law 24,241). Both employers (27% of salary) and employees (11%) contribute. For US citizens employed in Argentina, the employer's contributions are considered §402(b) foreign pension plan contributions: the employer's share is taxable to the employee as compensation in the year it vests, rather than deferred.⁶

There is no US-Argentina treaty article equivalent to the US-UK Article 18(1) that allows UK SIPP employer contributions to accumulate without immediate US taxation. The ANSES employer contribution is additional US taxable compensation each year. When you eventually receive an Argentine jubilación (ANSES pension) in retirement, it is taxable as ordinary income on your US return with no treaty reduction. The Foreign Tax Credit from any Argentine tax on the pension can offset the US liability, subject to the passive-income basket limitation and the same exchange-rate complications described above.

6. Argentine FCI Mutual Funds: PFIC Trap

All Argentine Fondos Comunes de Inversión (FCIs) — including money-market FCIs, fixed-income FCIs, and equity FCIs — are Passive Foreign Investment Companies (PFICs) for US tax purposes.⁷ This includes the popular "fondo de inversión en pesos" used for short-term cash management, FCI de renta fija holding Argentine government bonds, and FCI de renta variable investing in Argentine equities.

Under §1291, any gain or excess distribution from a PFIC is taxed at the highest ordinary income rate (37%) plus an interest charge calculated from the year of acquisition. A PFIC that has appreciated 15% over two years can net you less after US tax than if you had held the equivalent cash in a US-custodied money market fund — even before considering exchange rate translation.

Individual Argentine stocks listed on the BYMA (Bolsas y Mercados Argentinos) are not PFICs — a company's stock is not a PFIC unless the company itself earns primarily passive income or holds passive assets. US expats in Argentina who want local equity exposure can hold individual BYMA stocks directly without PFIC exposure, though Form 8938 and FBAR still apply if the account value exceeds the relevant thresholds.

Best practice: Keep your investment portfolio at a US-custodied brokerage (Schwab International, Interactive Brokers) using US-listed ETFs and individual US or foreign stocks. See our investing as a US expat guide for which brokerages accept Argentine-address clients.

7. Bienes Personales: Argentine Wealth Tax

Argentina's Bienes Personales is an annual tax on the net worldwide assets of Argentine tax residents as of December 31 each year.⁴ For the 2025 period (filed in 2026), the non-taxable minimum is approximately ARS 384.7 million (roughly $334,000 at a 1,150 ARS/USD rate — though this threshold is inflation-adjusted semi-annually).

Assets above the threshold are subject to Bienes Personales at progressive rates (0.5% to 1.5% on Argentine assets, historically higher on foreign assets — but Ley Bases unified the scale). Under the Milei reform's REIBP option, taxpayers can prepay Bienes Personales for 2023–2027 at a discounted rate and receive tax stability on covered patrimonial taxes through 2038.

For US expats: If you become an Argentine tax resident and have significant US brokerage and bank assets, Bienes Personales applies to those assets. Your US Vanguard account is part of your Argentine net wealth for this purpose. This creates a situation where the same assets are subject to both Argentine Bienes Personales and US estate and income taxes. The FTC cannot offset Bienes Personales against US income tax (it's a wealth tax, not an income tax), though it may be deductible as a foreign tax on Schedule A if you itemize. Specialist advice is essential before establishing Argentine tax residency with significant foreign assets.

8. Argentine Real Estate: §121, New CGT Exemption, and §988

§121 Primary Residence Exclusion

The US §121 exclusion — up to $250,000/$500,000 of capital gain on a primary residence sale — applies to foreign primary residences with no geographic restriction. A US citizen who owns and lives in an apartment in Buenos Aires for 2+ of the 5 years before sale can exclude up to $250,000 (single) or $500,000 (married) of gain from US gross income, exactly as if the property were in the US.⁷

Argentine CGT on Real Estate: Exempt as of January 1, 2026

Before the Milei reform, Argentine resident individuals owed 15% Ganancias on gains from selling property acquired after January 1, 2018. As of January 1, 2026, this capital gains tax on real estate is exempt — gains from the sale of Argentine real estate by resident individuals are no longer subject to Argentine income tax.² For US citizens, this means the §121 exclusion (if applicable) and no Argentine CGT on qualifying properties. For properties that don't qualify for §121, the full US capital gain applies with no Argentine FTC offset (since Argentina imposes no tax on the gain starting 2026).

§988 ARS Currency Gain

Argentine mortgages are unusual: historically, many Argentine residential transactions were conducted in USD cash rather than ARS financing, driven by the country's inflation history. If you do take an ARS-denominated mortgage, any gain from ARS depreciation at payoff relative to acquisition creates §988 ordinary income — the same trap as TRY mortgages in Turkey or BRL mortgages in Brazil. Given that Argentina has experienced annual inflation exceeding 50% in recent years, an ARS mortgage that was worth $50,000 at origination and is paid off for the equivalent of $30,000 in today's USD generates $20,000 of §988 ordinary income on the US return. The practical solution most US expats in Argentina use: buy in USD cash or hold any ARS-denominated liabilities for short periods only.

9. FBAR, FATCA, and Argentine Reporting

US citizens living in Argentina must comply with both US and Argentine reporting obligations for foreign financial accounts:

• FBAR (FinCEN 114): Any Argentine bank or brokerage account must be reported on the FBAR if the aggregate value of all foreign financial accounts exceeds $10,000 at any point in the calendar year. The FBAR is due April 15 with an automatic extension to October 15.⁸
• Form 8938 (FATCA): For US expats living abroad, the Form 8938 threshold is $200,000 on the last day of the year or $300,000 at any point during the year (single filer; double for MFJ). Form 8938 is filed with your 1040.
• FATCA Model 1 IGA: Argentina signed a FATCA Model 1 IGA with the US in December 2022, in force from fiscal year 2023.⁹ Argentine financial institutions now report US account holders' information to ARCA for automatic transmission to the IRS. This means your Argentine bank accounts are visible to the IRS through both FBAR and FATCA channels.
• Argentine ARCA filing: Argentine tax residents must file annual Ganancias and Bienes Personales declarations with ARCA. For employed workers, payroll withholding typically satisfies the annual tax obligation, but high earners, self-employed, or those with significant assets usually file a separate annual return.

10. Pre-Move Checklist for US Citizens Moving to Argentina

1. Choose FEIE or FTC before your first Argentine tax year. The FEIE election locks you in for 5 years without IRS approval to revoke. Run the numbers with a specialist before filing — the election is not reversible on a whim.
2. Liquidate FCI mutual funds before arriving. Any FCI you acquire as an Argentine tax resident becomes a PFIC. Sell Argentine-domiciled funds before establishing residency and replace them with US-listed ETFs at Schwab International or Interactive Brokers.
3. Establish Argentine tax residency timeline carefully. Argentina taxes residents on worldwide income. Understand the residency trigger (183 days in a calendar year or CUIT/CUIL registration) and plan your first year accordingly.
4. Sever US state tax domicile before moving. California (which doesn't recognize FEIE), New York, and other high-tax states can assert continuing tax jurisdiction if you maintain a state domicile. Change your driver's license, voter registration, banking address, and file a final part-year return in a zero-income-tax state if possible. See our state residency guide.
5. Assess Bienes Personales exposure. If you have more than ~$334,000 in worldwide net assets, you may owe Argentine wealth tax. Evaluate whether to prepay under REIBP or file annually — before you become an Argentine resident.
6. Model the ANSES double-contribution trap. If self-employed, the absence of a totalization agreement means full US SE tax (15.3%) plus Argentine contributions. An S-corp or foreign company structure may reduce SE tax — but requires advance setup.
7. Protect your US brokerage account. Fidelity and Vanguard restrict accounts for Argentine-address clients. Before moving, transfer your portfolio to Schwab International or Interactive Brokers, which maintain service for Argentine-resident US citizens. See our investing guide.
8. Avoid ARS-denominated mortgages where possible. The §988 currency gain trap on ARS mortgage payoff creates ordinary income even when the property itself is sold at a loss in USD terms.
9. Set up FBAR tracking from day one. Open a calendar-year balance tracking system for all Argentine accounts. The $10,000 FBAR threshold is an aggregate across all foreign accounts — easy to miss if you have multiple Argentine peso and USD accounts.
10. Register with ARCA (formerly AFIP) if self-employed. Whether as Monotributista or Autónomo, Argentine self-employed must register and file with ARCA. Failure to register creates penalties under Argentine law independent of US obligations.
