This problem involves calculating taxable income and personal income tax (PIT) payable in Vietnam, considering gross salary, mandatory insurance, personal deductions, and dependent deductions for families with children.
Question
Answer
To solve this problem, we need to apply the Personal Income Tax (PIT) regulations of Vietnam. Based on current standard regulations:
- Personal deduction (for the taxpayer):
million VND/month. - Dependent deduction (per person):
million VND/month.
1. Calculate Taxable Income
Taxable income is calculated by subtracting mandatory insurance contributions and all applicable deductions from the gross salary.
Given data:

3. Discussion on Social Equity
Dependent deductions support social equity in the following ways:
- Ability-to-Pay Principle: Social equity suggests that taxes should be based on a person’s actual capacity to pay. A person earning
million VND with three children has significantly less disposable income than a person earning the same amount with no dependents. Deductions ensure that the tax burden is shifted away from those with higher essential living costs. - Protection of Vulnerable Groups: By reducing the taxable income for parents, the government effectively provides financial support to children, ensuring they have better access to nutrition, healthcare, and education.
- Reducing Income Inequality: It prevents the tax system from inadvertently penalizing families, thereby promoting a more balanced distribution of wealth and supporting the social welfare of the family unit.
