Quick Answer
For Argentine Contractors Receiving Stock Options:
| Question | Answer |
|---|---|
| Can I receive stock options from a US company? | ✅ Yes, typically NSOs (not ISOs) |
| Will the US tax me? | ⚠️ Depends on where you worked during vesting |
| If 100% remote from Argentina? | ✅ No US tax - income is foreign-sourced |
| Will Argentina tax me? | ✅ Yes - taxed at exercise as ordinary income (up to 35%) |
| Capital gains when I sell shares? | ✅ Argentina taxes at 15% on the gain |
| Is there a US-Argentina tax treaty? | ❌ No - potential double taxation if work in US |
Key Principle
If you work 100% from Argentina, your stock option income is not US-sourced, meaning:
- ❌ No US income tax
- ❌ No US withholding
- ✅ Only Argentina taxes apply
If you work partially in the US, the US-sourced portion is taxable by the US, plus Argentina taxes the full amount (with potential for double taxation).
No Tax Treaty Between US and Argentina
Critical Fact: The United States and Argentina do NOT have an income tax treaty.
What This Means
| Aspect | Impact |
|---|---|
| No treaty benefits | Cannot claim reduced withholding rates |
| No tie-breaker rules | Both countries may claim tax jurisdiction |
| Double taxation possible | If work performed in US, both countries may tax |
| No exchange of information | Limited cooperation between tax authorities |
| No permanent establishment rules | Complex determination of taxing rights |
Practical Implication
For most contractors working 100% remotely from Argentina:
- The lack of treaty doesn’t matter
- US doesn’t tax foreign-source income regardless of treaty status
- Only becomes an issue if you work physically in the US
Types of Equity Compensation
NSOs (Non-Qualified Stock Options)
Most common for contractors.
| Feature | Details |
|---|---|
| Who can receive | ✅ Employees, contractors, advisors - anyone |
| Tax event | At exercise (when you buy the shares) |
| Taxable amount | ”Spread” = Fair Market Value - Strike Price |
| Tax type | Ordinary income (not capital gains) |
| US tax for NRA | Only if services performed in US |
Example:
Grant: 1,000 options at $10 strike priceExercise: When stock is $50/shareSpread: $50 - $10 = $40/shareTaxable income: $40 × 1,000 = $40,000ISOs (Incentive Stock Options)
NOT available to contractors.
| Feature | Details |
|---|---|
| Who can receive | ❌ US employees ONLY |
| Contractors eligible? | ❌ No |
| International workers | ❌ No special benefit even if eligible |
| Why not for contractors | IRS rules require employee status |
If a US company offers you ISOs as a contractor, they’re making an error.
RSUs (Restricted Stock Units)
Can be granted to contractors.
| Feature | Details |
|---|---|
| Who can receive | ✅ Employees and contractors |
| Tax event | At vesting (when shares are delivered) |
| Taxable amount | Fair market value of shares at vesting |
| Tax type | Ordinary income |
| US tax for NRA | Only if services performed in US |
Example:
Grant: 100 RSUs vesting over 4 years (25/year)Year 1 vesting: 25 shares when FMV = $100Taxable income Year 1: 25 × $100 = $2,500US Tax Treatment for Argentine Contractors
The Critical Question: Where Were Services Performed?
The US taxes non-resident aliens on a territorial basis for compensation income. The key factor is:
Where were you physically located when performing the services that earned the equity?
| Location of Work | US Tax Result |
|---|---|
| 100% in Argentina | ❌ No US tax - foreign source income |
| 100% in US | ✅ 30% US tax on the full spread |
| Mixed (some US, some Argentina) | ⚠️ Apportioned based on work days |
Scenario 1: 100% Remote from Argentina
The typical case for Argentine contractors.
Facts:
- You’re hired as a contractor by a US company
- You work 100% remotely from Argentina
- You never travel to the US for work
- You receive NSO grants that vest over 4 years
US Tax Result:
- ✅ No US income tax on exercise
- ✅ No US withholding required
- ✅ No Form 1042-S required (likely)
- ✅ Full spread is foreign-source income
- ✅ Only Argentina taxes apply
Why? The source of compensation income is where services are performed, not where the company is located. Since you worked in Argentina, the income is Argentina-sourced.
Scenario 2: Mixed Location (Some Work in US)
When you travel to the US for work.
Facts:
- You work as a contractor from Argentina
- You travel to the US for meetings/onsite work
- During 4-year vesting: 350 days in US, 950 days in Argentina (total 1,300 work days)
- You exercise NSOs with $100,000 spread
Allocation Calculation:
US days: 350 / 1,300 = 26.9%Argentina days: 950 / 1,300 = 73.1%
US-source income: $100,000 × 26.9% = $26,900Foreign-source income: $100,000 × 73.1% = $73,100US Tax Result:
- ⚠️ $26,900 is US-source income
- ⚠️ Subject to 30% US withholding = $8,070
- ⚠️ Form 1042-S required to report
- ⚠️ Must file US tax return to claim any refund
Argentina Tax Result:
- ⚠️ Full $100,000 taxed in Argentina
- ⚠️ No foreign tax credit for US tax (no treaty)
- ⚠️ Potential double taxation on US-source portion
Argentine Tax Obligations
Income Tax (Impuesto a las Ganancias)
Argentina taxes residents on worldwide income, including equity compensation from foreign companies.
2025 Tax Rates (Progressive):
| Taxable Income (ARS) | Rate |
|---|---|
| Up to threshold | 5% |
| Middle brackets | 9% - 31% |
| Over ~53,153,257 ARS | 35% |
Note: Thresholds are updated periodically due to inflation. The 35% top rate applies to roughly USD $50,000+ of taxable income (depending on exchange rate).
When Stock Options Are Taxed in Argentina
Tax Event: At exercise (when you buy the shares)
Taxable Amount:
Fair Market Value at exercise - Strike Price = Taxable IncomeClassification: Ordinary income (employment/service income category)
Reporting:
- Report through annual income tax return (Ganancias)
- Due dates typically in June following the tax year
- May require estimated payments during the year
Capital Gains on Share Sales
After you exercise options and hold shares:
| Aspect | Treatment |
|---|---|
| Tax event | When you sell the shares |
| Taxable amount | Sale price - Exercise date FMV |
| Tax rate | 15% flat rate |
| Exemption | Shares traded on Buenos Aires Stock Exchange may be exempt |
Example:
Exercise: Buy shares at $50 FMV (already taxed as income)Sell later: Shares at $75Capital gain: $75 - $50 = $25/shareArgentine tax: $25 × 15% = $3.75/shareUS Shares (not traded on BYMA):
- No exemption applies
- 15% capital gains tax on the gain
- Report via annual tax return
Practical Examples
Example 1: NSO Grant - 100% Argentina Work
Situation:
- Argentine contractor working 100% remote from Buenos Aires
- Granted 5,000 NSOs at $10 strike price over 4-year vest
- Year 4: Exercises all options when FMV = $60/share
- Exchange rate: 1 USD = 1,000 ARS
Calculations:
Spread per share: $60 - $10 = $50Total spread: $50 × 5,000 = $250,000 USD
US Tax:- Income source: 100% Argentina (foreign)- US tax: $0- US withholding: $0- Form 1042-S: Not required
Argentine Tax (Ganancias):- Taxable income: $250,000 USD × 1,000 = 250,000,000 ARS- Tax rate: 35% (high income)- Approximate tax: 87,500,000 ARS (~$87,500 USD)Net Proceeds:
Gross value: $300,000 (5,000 × $60)Cost: $50,000 (5,000 × $10)Argentine tax: ~$87,500Net: ~$162,500Example 2: NSO Grant - Mixed Location
Situation:
- Argentine contractor who traveled to US for some work
- Same grant as Example 1
- During vesting: 200 days in US, 800 days in Argentina
Calculations:
US portion: 200/1,000 = 20%Argentina portion: 800/1,000 = 80%
Total spread: $250,000
US-Source Income: $250,000 × 20% = $50,000Foreign-Source Income: $250,000 × 80% = $200,000
US Tax:- US-source income: $50,000- 30% withholding: $15,000- Form 1042-S: Required
Argentine Tax:- Taxable income: Full $250,000- Tax: ~$87,500 (no credit for US tax - no treaty)
Total Tax Burden:- US: $15,000- Argentina: $87,500- Total: $102,500 (vs. $87,500 if 100% Argentina)- Double taxation: $15,000 on US-source portionExample 3: RSU Vesting
Situation:
- Granted 1,000 RSUs vesting 25% per year
- Year 1: 250 shares vest when FMV = $40
- 100% work from Argentina
Calculations:
Vesting value: 250 × $40 = $10,000 USD
US Tax:- 100% foreign source- US tax: $0
Argentine Tax:- Taxable income: $10,000 × 1,000 ARS = 10,000,000 ARS- Progressive rate applies based on total incomeDouble Taxation Risk
The Problem
Since there’s no US-Argentina tax treaty:
| If You | US Tax | Argentina Tax | Double Taxed? |
|---|---|---|---|
| Work 100% in Argentina | $0 | Full amount | ❌ No |
| Work partially in US | 30% on US portion | Full amount | ✅ Yes, on US portion |
| Live in US temporarily | Full amount | May claim exemption | ⚠️ Depends |

Common Mistakes to Avoid
❌ Mistake 1: Assuming US Always Taxes
Wrong: “US company = US tax”
Correct: US only taxes income sourced in the US. Remote work from Argentina = foreign source = no US tax.
❌ Mistake 2: Not Reporting in Argentina
Wrong: “US company paid me, Argentina doesn’t know”
Correct: Argentina taxes worldwide income. US equity compensation must be reported.
❌ Mistake 3: Ignoring Work Location Tracking
Wrong: Not documenting where work was performed
Correct: Keep detailed records of work days by country, especially if any US travel.
❌ Mistake 4: Confusing Exercise with Sale
Wrong: Waiting until share sale to report income
Correct:
- Exercise/vesting = ordinary income tax event
- Sale = capital gains tax event (if gain)
❌ Mistake 5: Using Wrong Exchange Rate
Wrong: Using any convenient exchange rate
Correct: Use official rates (AFIP/ARCA published rates) on transaction dates.
❌ Mistake 6: Not Planning for Taxes
Wrong: Exercising without funds for tax
Correct: Set aside 35%+ of spread for Argentine taxes before spending proceeds.
❌ Mistake 7: Expecting Treaty Benefits
Wrong: Claiming tax treaty benefits
Correct: No US-Argentina tax treaty exists. No reduced rates or credits available.
