How to calculate the latest family deduction
According to the State's regulations, family deduction is the right of employees when they have dependents, who must be supported or cared for. The current family deduction level has also changed according to the new tax rate of the State.
Family deduction is the amount deducted from personal income taxable income before calculating tax on income from salaries and wages of taxpayers who are resident individuals.
Family deductions include the following two items:
- Family deduction for the taxpayer himself (this is a deduction that taxpayers who are resident individuals are naturally entitled to).
- Family deduction for dependents
Note, taxpayers are only allowed to deduct dependents if they have registered a tax code in accordance with regulations.
People with income below 11 million VND/month will not have to pay tax so there will be no family deduction.
The deduction for each dependent is 4.4 million VND/month. Each additional dependent will be deducted an additional 4.4 million VND/month.
When wanting to deduct family circumstances, taxpayers must register dependents according to the instructions below.
Each dependent is also provided with a tax identification number. You can look up your dependent's tax identification number yourself by following this article.
You can simply understand the tax calculation formula when having dependents with the example of a person earning 20 million VND and having 1 dependent.
First, you need to calculate the taxable income according to the formula: Salary received - 11 million VND - 4.4 million VND. Applying this formula, we will calculate the taxable income as:
20,000,000 – 11,000,000 – 4,400,000 = 4,600,000 (VND).
So from there we will know the tax payable of 4,600,000 is 4,600,000 * 5% = 230,0000 (VND) .
