Formula for calculating PIT based on the partially progressive tax schedule
PIT for income from salaries and wages is calculated according to the following general formula:
PIT payable = Taxable income x Applicable tax rate
Where Taxable income is determined by:
Taxable income = Assessable income – Deductions
Steps to determine assessable income
- Assessable income: Is the total salary, wages, remuneration, bonuses, and benefits in cash or non-cash form that the employee receives from the business.
- Deductions include:
- Personal relief for the taxpayer.
- Family relief for dependents (according to 2026 regulated levels).
- Charitable, humanitarian, and educational contributions.
- Mandatory insurance contributions (Social Insurance, Health Insurance, Unemployment Insurance).
Details of the 2026 partially progressive tax schedule
The partially progressive tax schedule applied to average monthly taxable income is divided into 7 brackets with progressive tax rates ranging from 5% to 35%. The application of this tax schedule requires absolute accuracy in calculating the tax amount for each bracket.
| Tax Bracket | Monthly Taxable Income (Million VND) | Tax Rate |
|---|---|---|
| Bracket 1 | Up to 5 million VND | 5% |
| Bracket 2 | Over 5 million to 10 million VND | 10% |
| Bracket 3 | Over 10 million to 18 million VND | 15% |
| Bracket 4 | Over 18 million to 32 million VND | 20% |
| Bracket 5 | Over 32 million to 52 million VND | 25% |
| Bracket 6 | Over 52 million to 80 million VND | 30% |
| Bracket 7 | Over 80 million VND | 35% |
Illustrative example of tax calculation for an employee
Suppose employee A has an assessable income after deducting mandatory insurance contributions of 25 million VND/month. This person has 1 dependent (entitled to a relief of 4.4 million VND/month according to new regulations) and a personal relief level of 11 million VND/month.
Calculation steps:
- Total deductions: 11 million + 4.4 million = 15.4 million VND.
- Taxable income: 25 million – 15.4 million = 9.6 million VND.
- Apply progressive tax schedule:
- Bracket 1: 5 million x 5% = 0.25 million VND.
- Bracket 2: (9.6 million – 5 million) x 10% = 0.46 million VND.
- Total PIT payable: 0.25 + 0.46 = 0.71 million VND (710,000 VND).
Important notes for businesses in 2026
To optimize PIT management and compliance, businesses need to pay attention to the following points:
