Corporate income tax payable = Taxable income x Preferential tax rate

In there:

  • Taxable income: Is taxable income after deducting reasonable expenses, incentives and losses from previous years.

  • Corporate Income Tax Payable: The amount of corporate income tax payable to the tax authority after applying incentives.

Steps to calculate corporate income tax

To determine the amount of corporate income tax payable for 2025, businesses need to follow basic steps. This process helps businesses apply tax incentives correctly, ensuring accuracy and legality in declaration. Below are detailed step-by-step instructions from determining taxable income, calculating taxable income to applying preferential tax rates according to the provisions of the Corporate Income Tax Law 2025.

First, it is necessary to determine taxable income. This is the actual revenue in the tax period after deducting reasonable deductible expenses and non-taxable income.

Next, determine taxable income. This is the taxable income after deducting incentives, exemptions and losses carried forward from previous years, helping to accurately determine the basis for applying the tax rate.

Finally, preferential tax rates apply. The tax rate is determined based on the industry, investment location or project encouraged under the Corporate Income Tax Law 2025. In some special cases, enterprises may be subject to a lower tax rate than 15%. 

Illustrative example of corporate income tax calculation

Suppose enterprise A operates in the high-tech sector, which is in the group of industries that enjoy tax incentives. This is a sector that the state encourages investment in, so the enterprise will be subject to preferential tax rates according to the provisions of the Corporate Income Tax Law 2025.

In 2025, the total revenue of the enterprise is 10 billion VND. From this total revenue, the enterprise is allowed to deduct reasonable expenses related to production and business activities, in this case 4 billion VND. After deducting expenses, the remaining pre-tax profit of the enterprise is 6 billion VND. This is the income that will be used as the basis for calculating taxes.

The entire profit of 6 billion VND is determined as preferential income, because the enterprise belongs to a preferential industry. The preferential tax rate applied in this case is 10%, lower than the standard tax rate of 20% for normal enterprises.

Corporate income tax payable = taxable income X preferential tax rate = 6 billion VND X 10% = 600 million VND

Thus, after applying tax incentives, enterprise A will have to pay VND 600 million in corporate income tax for 2025. This method helps enterprises take full advantage of the incentives allowed by law, while ensuring that tax obligations are performed correctly and legally.
