Personal Income Tax 2026: How to Calculate Net vs Gross Salary in Vietnam

When you receive a job offer in Vietnam, the salary listed is almost always gross – meaning before deductions. Understanding the difference between gross and net is essential to know what you'll actually take home each month.

This guide walks through the complete process for calculating Vietnamese personal income tax (Thuế TNCN).

1. Gross vs Net Salary: What's the Difference?

	Gross Salary	Net Salary
Definition	Salary stated in your contract	Salary after taxes and insurance
Who pays	Includes employee insurance contributions	The amount you actually receive
Used when	Job postings, negotiations	Personal budgeting

Reality check: When a company advertises "20 million VND salary," that's gross. You may take home 2–5 million less depending on your tax bracket.

2. Deductions Before Applying Tax

Before calculating the tax, several deductions are subtracted from gross salary:

2.1 Mandatory Insurance (Employee Share)

Insurance Type	Rate
Social Insurance (BHXH)	8%
Health Insurance (BHYT)	1.5%
Unemployment Insurance (BHTN)	1%
Total	10.5%

Note: Contributions are capped at 20x the minimum regional wage (approximately 36–40 million VND depending on region in 2026).

2.2 Dependent Deductions

Category	Monthly Deduction
Personal deduction (self)	11,000,000 VND
Each dependent (child/elderly parent)	4,400,000 VND

3. Progressive Tax Bracket Table 2026

Bracket	Monthly Taxable Income	Tax Rate
1	Up to 5 million	5%
2	5–10 million	10%
3	10–18 million	15%
4	18–32 million	20%
5	32–52 million	25%
6	52–80 million	30%
7	Over 80 million	35%

4. Step-by-Step Calculation Example

Example: 20 million VND gross, no dependents

Step 1 – Subtract insurance:

20,000,000 × 10.5% = 2,100,000 VND

After-insurance income = 20,000,000 – 2,100,000 = 17,900,000 VND

Step 2 – Subtract personal deduction:

Taxable income = 17,900,000 – 11,000,000 = 6,900,000 VND

Step 3 – Apply progressive brackets:

Bracket	Amount	Rate	Tax
Bracket 1	5,000,000	5%	250,000
Bracket 2	1,900,000	10%	190,000
Total tax			440,000 VND

Step 4 – Net salary:

20,000,000 – 2,100,000 – 440,000 = 17,460,000 VND

So a 20 million VND gross salary nets approximately 17.46 million VND.
