What is PIT Withholding
PIT withholding is the monthly deduction of personal income tax by your employer from your salary.
How It Works
- Your employer calculates your monthly taxable income
- Personal and dependant deductions are applied
- Tax is calculated using progressive rates
- Amount is deducted and paid to tax authority on your behalf
Key Points
- Automatic: Your employer handles it
- Estimated: Based on monthly salary, not full-year position
- Provisional: May not reflect your actual annual tax liability
Example
Monthly Salary: 40,000,000 VND Personal Deduction: 11,000,000 VND
Monthly Withholding Calculation:
- Taxable income: 40,000,000 - 11,000,000 = 29,000,000 VND
- Tax: 5% on first 5M + 10% on next 5M + 15% on next 8M + 20% on remaining 11M
- Monthly tax withheld: ~3,700,000 VND
What is PIT Finalization
PIT finalization is the annual reconciliation of your actual tax liability versus what was withheld throughout the year.
Purpose
- True-up your actual tax position
- Claim deductions not reflected in monthly withholding
- Report all income from all sources
- Settle any difference (refund or payment)
Filing Period
- Standard deadline: Within 90 days after year-end (by March 31)
- Departure finalization: Within 60 days of departure
- Multi-employer: Personal filing required
When Finalization is Required
You MUST file PIT finalization if any of these apply:
Mandatory Finalization Situations
| Situation | Why Finalization is Needed |
|---|---|
| Multiple employers during the year | Each employer calculates independently |
| Changes in deductions | Monthly withholding doesn't reflect changes |
| Additional income sources | Not captured in employer withholding |
| Departure from Vietnam | Required by law before/at departure |
| Employer authorization | Employer finalizes on your behalf |
| Tax refund expected | To claim overpaid tax |
Detailed Scenarios
1. Multiple Employers
- You worked for Company A (Jan-Jun) and Company B (Jul-Dec)
- Each employer calculated tax independently
- Combined income may push you into higher bracket
- Personal deduction can only be claimed once
2. Deduction Changes
- You had a child during the year
- Started/ended dependant claims
- Your deduction eligibility changed
3. Other Income
- Income from overseas
- Investment income
- Rental income in Vietnam
- Freelance/consulting income
When You Can Skip Finalization
You MAY NOT need to file finalization if:
Conditions Met (ALL must apply)
- ✅ Single employer for entire year
- ✅ No changes in deductions
- ✅ No additional income sources
- ✅ Employer authorized to finalize on your behalf
- ✅ No tax refund expected
Employer-Authorized Finalization
If you meet the conditions above, your employer can include you in their annual finalization filing.
Requirements:
- Sign authorization form to employer
- Confirm no other income sources
- Verify deduction information is correct
Note: Even if eligible, you may still want to file personally if:
- You suspect over-withholding
- You have deductions not accounted for
- You want more control over the process

Example Scenario
Your situation:
- Monthly salary: 50,000,000 VND
- Worked Jan-Dec with one employer
- Had a baby in July (new dependant)
Monthly withholding (Jan-Jun):
- Taxable: 50,000,000 - 11,000,000 = 39,000,000 VND
- Monthly tax: ~5,850,000 VND
- Total withheld (6 months): 35,100,000 VND
Monthly withholding (Jul-Dec):
- New dependant deduction: +4,400,000 VND
- Taxable: 50,000,000 - 11,000,000 - 4,400,000 = 34,600,000 VND
- Monthly tax: ~4,780,000 VND
- Total withheld (6 months): 28,680,000 VND
Annual total withheld: 63,780,000 VND
Finalization:
- Annual income: 600,000,000 VND
- Annual personal deduction: 132,000,000 VND
- Annual dependant deduction (6 months): 26,400,000 VND
- Correct annual taxable: 441,600,000 VND
- Correct annual tax: ~57,840,000 VND
Refund due: 63,780,000 - 57,840,000 = 5,940,000 VND
Key Takeaways
- Withholding is provisional – Monthly amounts are estimates
- Finalization is the true-up – Reconciles actual position
- Multi-employer = Must file – Personal finalization required
- Changes = File – Deduction changes require finalization
- Don't miss refunds – Many foreigners overpay without knowing
