How to Read a Payslip: Understanding Gross Salary, Net Salary, Personal Income Tax, and Social Insurance
1. What Is a Payslip?
A payslip is a document that provides a breakdown of an employee's income, allowances, deductions, and the amount they actually receive for a specific pay period.
However, many employees only focus on one number:
“How much am I getting this month?”
A payslip can actually contain many different components:
Base Salary + Allowances + Bonuses − Social Insurance − Health Insurance − Unemployment Insurance − Personal Income Tax − Other Deductions = Take-Home Pay
That's why knowing how to read a payslip helps you understand exactly what your employer is paying you and why the amount deposited into your bank account may differ from the salary stated in your employment contract.
2. What Does a Standard Payslip Include?
The exact format may vary between companies and payroll systems. However, a typical payslip usually contains the following sections.
1. Employee Information
- Full name
- Employee ID
- Department
- Job title
- Pay period
2. Earnings
This may include:
- Base salary
- Allowances
- Commission
- Bonuses
- Overtime pay
- Other earnings
3. Insurance Contributions
The employee's portion may include:
- Social insurance (BHXH)
- Health insurance (BHYT)
- Unemployment insurance (BHTN)
4. Personal Income Tax
If applicable, the payslip may show:
- Taxable income
- Eligible deductions
- Assessable income
- Personal income tax payable
5. Net Pay
This is the final amount paid to the employee after earnings and applicable deductions have been calculated.
3. What Is the Difference Between Gross and Net Salary?
This is one of the most important concepts to understand when reading a payslip.
What Is Gross Salary?
Gross salary is the total salary and income agreed upon before applicable employee-paid contributions, taxes, and other deductions are taken into account.
A simple way to think about it is:
Gross → Insurance + Tax + Other Deductions → Net
For example:
Gross salary: VND 20,000,000/month
After applicable insurance contributions and taxes are calculated, the actual amount received will generally be lower than VND 20 million.
What Is Net Salary?
Net salary is the amount an employee actually receives after applicable deductions have been taken into account according to the employment agreement and relevant regulations.
For example:
Net salary: VND 18,000,000/month
You should not automatically assume that the employer will always pay exactly VND 18 million under every circumstance. Check the employment contract and how the company handles taxes, insurance, allowances, and other forms of compensation.
Gross vs. Net Salary
| Criteria | Gross Salary | Net Salary |
|---|---|---|
| Meaning | Total income before applicable deductions | Actual take-home amount |
| Insurance/tax | May be shown before deductions | Generally reflects applicable deductions |
| Amount received | Usually higher than Net | Actual amount received |
| When reviewing an offer | Check what is included | Confirm how taxes and insurance are handled |
Important: Don't look only at the Gross or Net figure. Check the income components and deductions as well.
4. What Are Social Insurance, Health Insurance, and Unemployment Insurance?
These are commonly shown under the deductions or insurance contribution section of a payslip.
Under current regulations, for Vietnamese employees subject to the applicable rules, the employee contribution is 10.5% of the salary used as the contribution base, consisting of:
- Social Insurance (BHXH): 8%
- Health Insurance (BHYT): 1.5%
- Unemployment Insurance (BHTN): 1%
Vietnam Social Security confirms these rates have applied since July 1, 2025 and were not changed by the 2024 Social Insurance Law.
Example
Suppose the salary used as the insurance contribution base is:
VND 20,000,000
The employee contributions can be illustrated as follows:
| Contribution | Rate | Amount |
|---|---|---|
| Social Insurance | 8% | VND 1,600,000 |
| Health Insurance | 1.5% | VND 300,000 |
| Unemployment Insurance | 1% | VND 200,000 |
| Total | 10.5% | VND 2,100,000 |
Note: This is only an illustrative example. The actual insurance contribution base and amount depend on the applicable regulations and the employee's specific circumstances.
5. How Is Personal Income Tax Calculated?
Personal Income Tax (PIT) is a tax payable by individuals whose income falls within the taxable scope under applicable regulations.
A simplified way to understand the calculation is:
Taxable Income
→ Subtract eligible insurance contributions
→ Subtract personal and dependent deductions and other eligible deductions
→ Assessable Income
→ Apply the applicable tax brackets
→ PIT Payable
From the 2026 tax year, the personal deduction is VND 15.5 million/month for the taxpayer and VND 6.2 million/month for each dependent.
For resident individuals earning employment income, the progressive tax schedule from the 2026 tax year has five brackets, with rates ranging from 5% to 35%.
| Monthly Assessable Income | Tax Rate |
|---|---|
| Up to VND 10 million | 5% |
| Over VND 10–30 million | 10% |
| Over VND 30–60 million | 20% |
| Over VND 60–100 million | 30% |
| Over VND 100 million | 35% |
Important: Your Entire Salary Is Not Taxed at One Rate
This is a common misunderstanding.
For example, if your assessable income exceeds VND 10 million, only the portion falling into each tax bracket is taxed at the corresponding rate.
You therefore cannot simply multiply your entire salary by 20%, 30%, or 35% because your income falls within a particular bracket.
6. Example: How to Read a Payslip
Suppose an employee has:
- Gross salary: VND 20,000,000
- Salary used as the insurance contribution base: VND 20,000,000
- No dependents
- No other special deductions
Step 1: Calculate Employee Insurance Contributions
Social Insurance:
VND 20,000,000 × 8% = VND 1,600,000
Health Insurance:
VND 20,000,000 × 1.5% = VND 300,000
Unemployment Insurance:
VND 20,000,000 × 1% = VND 200,000
Total:
VND 2,100,000
Step 2: Determine Assessable Income
Using this simplified example:
VND 20,000,000 − VND 2,100,000 − VND 15,500,000 = VND 2,400,000
This is below the first tax bracket in 2026, so the example results in no PIT payable.
Step 3: Calculate Take-Home Pay
If there are no other deductions:
VND 20,000,000 − VND 2,100,000 = VND 17,900,000
Therefore:
Gross = VND 20,000,000
Illustrative Net Pay = VND 17,900,000
This is a simplified example for understanding how to read a payslip, not a calculation that applies to every employee.
7. Why Is Your Take-Home Pay Different From the Salary in Your Contract?
This is a common question:
“My contract says VND 20 million. Why did I only receive VND 17–18 million?”
The most common reason is that the salary stated in the contract may be a Gross salary, while the amount deposited into your bank account is the Net salary after applicable deductions.
For example:
Gross Salary: VND 20 million
↓
Social Insurance + Health Insurance + Unemployment Insurance
↓
Personal Income Tax, if applicable
↓
Other Applicable Deductions
↓
Net Salary
Your monthly take-home pay can also change because of:
- Actual working days
- Unpaid leave
- Overtime
- Bonuses
- Commissions
- Allowances
- Retroactive payments
- Other deductions
- Changes in tax deduction information
Therefore, if the amount you receive differs from the figure in your contract, don't look only at Net Pay. Check the entire payslip.
8. Is the Salary Used for Insurance Contributions Always the Same as Gross Salary?
You should not assume that these two figures are always the same.
The salary used as the basis for mandatory social insurance contributions is determined according to applicable regulations and the specific components of the employee's compensation.
For employees subject to mandatory social insurance, the contribution base generally includes salary according to the job or position and qualifying allowances and additional amounts under the applicable rules.
Therefore, when reading a payslip, it is useful to distinguish between:
Gross Salary ≠ Insurance Contribution Base ≠ Taxable Income ≠ Net Salary
These figures are related, but they are not necessarily identical.
9. The 5 Most Important Items to Check on Your Payslip
If you don't want to read every line, start with these five sections:
1. Gross Salary
How much total income are you receiving before deductions?
2. Insurance Contribution Base
What salary amount is being used to calculate your insurance contributions?
3. PIT / Taxable Income
What income is being used to determine your personal income tax?
4. Total Deductions
How much has been deducted from your earnings?
5. Net Pay
How much are you actually receiving?
You can remember the process as:
Gross → Insurance & Tax → Deductions → Net Pay
10. Common Mistakes When Reading a Payslip
Mistake 1: Assuming Gross = Take-Home Pay
Gross is generally the amount before applicable deductions.
Mistake 2: Assuming Your Entire Salary Is Taxed at One Rate
Personal income tax is calculated progressively based on assessable income.
Mistake 3: Assuming 10.5% Insurance Is Always Calculated on Your Entire Gross Salary
You first need to identify the salary used as the insurance contribution base.
Mistake 4: Checking Only Net Pay
Net tells you how much you receive. It does not explain why you receive that amount.
Mistake 5: Ignoring Allowances and Bonuses
A month with a bonus or overtime can result in a different total income compared with previous months.
11. Why Should Companies Provide Transparent Payslips?
A clear payslip doesn't just tell employees how much they receive.
It helps employees understand:
What the company pays → What is deducted → How much insurance is contributed → How tax is calculated → How much they actually receive
For HR, managing payslips through a centralized system can also help:
- Reduce manual payroll distribution
- Minimize data errors
- Centralize payroll information
- Improve access to historical records
- Allow employees to check information independently
This is also an important part of Employee Self-Service (ESS).

FAQ: Frequently Asked Questions About How to Read a Payslip
Is Gross Salary the same as take-home pay?
No. Gross salary generally refers to total income before applicable deductions. Take-home pay, or Net Pay, is the amount actually received after insurance contributions, taxes, and other applicable deductions.
Does Net Salary include Personal Income Tax?
This depends on the terms of the employment agreement and the company's payroll policy. If salary is agreed on a Net basis, the employer may need to gross up the amount to determine the applicable tax and related obligations.
How much insurance does an employee contribute?
For Vietnamese employees subject to the applicable rules, the employee contribution is currently 10.5%, consisting of 8% Social Insurance, 1.5% Health Insurance, and 1% Unemployment Insurance.
Why can two employees with the same Gross Salary have different Net Salaries?
Differences may result from dependents, taxable income, the insurance contribution base, actual working days, bonuses, allowances, or other deductions.
Should I check my payslip every month?
It's a good practice. Regularly reviewing your payslip can help you identify discrepancies in salary, working days, allowances, insurance contributions, taxes, or other deductions early.
Conclusion
Knowing how to read a payslip helps employees understand their compensation instead of focusing only on the amount deposited into their bank account.
Remember these four key concepts:
Gross Salary → Insurance Contribution Base → Taxable Income → Net Pay
Where:
- Gross Salary: Total income before applicable deductions
- Insurance Contribution Base: Salary amount used to calculate insurance contributions
- Taxable Income: Income used to determine personal income tax
- Net Pay: Actual take-home amount
Especially in 2026, when Vietnam's personal income tax rules include important changes to personal deductions and tax brackets, employees should pay closer attention to the details on their payslips rather than looking only at Net Pay.
A transparent payslip helps employees understand not only “how much am I getting?” but also “why am I getting this amount?”
