Types of Equity Compensation
Foreign employees in Vietnam often receive equity compensation. Understanding the tax treatment is crucial:
Common Types
| Type | Description | Tax Point |
|---|---|---|
| Stock Options | Right to buy shares at fixed price | Exercise date |
| RSUs | Restricted Stock Units - free shares | Vesting date |
| Performance Shares | Shares based on performance goals | Vesting date |
| ESPP | Employee Stock Purchase Plans | Purchase date |
| Phantom Stock | Cash bonus tied to stock price | Payment date |
When is Equity Income Taxed?
For Tax Residents
Equity income is taxable in Vietnam when:
- The vesting condition is met (for RSUs, performance shares)
- The option is exercised (for stock options)
- The purchase is made (for ESPP)
Income Allocation
Vietnam taxes the portion of equity income related to work performed in Vietnam:
Formula:
Vietnam-taxable portion = Total equity income × (Days working in Vietnam ÷ Total days in vesting period)
Example
You receive 1,000 RSUs that vest after 3 years:
- Total vesting period: 1,095 days
- Days working in Vietnam: 700 days
- Fair market value at vesting: $50/share
Calculation:
- Total income: 1,000 × $50 = $50,000
- Vietnam portion: $50,000 × (700/1,095) = $31,963
- Taxable in Vietnam: $31,963
Tax Calculation Methods
Method 1: Average Tax Rate
For residents, equity income can be added to regular employment income and taxed at your average rate:
- Add equity income to annual employment income
- Calculate total tax using progressive brackets
- Divide by total income to get average rate
- Apply average rate to equity income
Method 2: Separate Taxation
Equity income may be taxed separately at progressive rates (5-35%) on the taxable amount.
Which Method Applies?
The method depends on:
- Type of equity compensation
- Your employer's arrangements
- Tax authority guidance
Note: Consult with a tax professional to determine the optimal method for your situation.
RSU Taxation
Tax Point
RSUs are taxed when they vest (become unconditional).
Taxable Amount
Taxable Income = Number of RSUs × Fair Market Value at Vesting
Example
Scenario:
- 500 RSUs vest on June 30, 2024
- FMV at vesting: $45/share
- You worked in Vietnam for 200 of 365 days in vesting year
Calculation:
- Gross income: 500 × $45 = $22,500
- Vietnam allocation: $22,500 × (200/365) = $12,329
- Convert to VND at official rate
- Apply progressive tax rates
Withholding
Employers may be required to withhold tax on RSU income. If not:
- You must declare in annual finalization
- May need to make provisional payments
Stock Options Taxation
Tax Point
Stock options are taxed when exercised, not when granted or vested.
Taxable Amount
Taxable Income = (FMV at Exercise - Exercise Price) × Number of Options
Example
Scenario:
- Granted option to buy 1,000 shares at $20
- Exercise price: $20/share
- FMV at exercise: $35/share
- Vietnam work days: 180 of 365 in exercise year
Calculation:
- Gain per share: $35 - $20 = $15
- Total gain: 1,000 × $15 = $15,000
- Vietnam portion: $15,000 × (180/365) = $7,397
- Tax at progressive rates on $7,397
Qualifying vs Non-Qualifying Options
| Type | Tax Treatment |
|---|---|
| Non-Qualified Stock Options (NQSO) | Full gain taxed as ordinary income |
| Incentive Stock Options (ISO) | May receive different treatment (rare for Vietnam) |
Reporting Requirements
Annual Finalization
Equity income must be reported in your annual PIT finalization:
- Gather documents:
- Grant agreements - Exercise/vesting statements - Brokerage statements - FMV documentation
- Calculate Vietnam-taxable portion:
- Track days in Vietnam - Apply allocation formula - Convert to VND
- Include in Form 02/CK-TNCN:
- Report as "other income" - Attach supporting documentation
Currency Conversion
Use the official exchange rate announced by the State Bank of Vietnam on the date income is recognized.
Deadlines
- Annual finalization: By March 31 of following year
- Departure: Before leaving Vietnam
Common Issues
Issue 1: No Withholding by Employer
Many foreign employers don't withhold Vietnam tax on equity income.
Solution:
- Track your equity income
- Make voluntary provisional payments
- Include in annual finalization
Issue 2: Missing Documentation
FMV documentation may be difficult to obtain.
Solution:
- Request statements from broker/employer
- Use official closing prices for public companies

Issue 3: Currency Conversion
Determining correct exchange rate.
Solution:
- Use State Bank of Vietnam rates
- Document rate used

If your home country also taxes equity income:
- Check your DTA for income from employment articles
- Allocate income between countries based on work days
- Claim foreign tax credit in home country
- Obtain Tax Residency Certificate if needed
