Key information about corporate income tax

Corporate income tax is a tax that every business is obligated to pay according to legal regulations. In this article, let’s delve into some basic concepts related to corporate income tax.

What is corporate income tax?

Corporate income tax (CIT) is a type of tax imposed on the income of businesses, commercial organizations, or equivalent entities. This is a tax that businesses are required to pay based on their annual income. Corporate income tax is calculated on the net income (income after deductions) of the business, which means the income remaining after subtracting expenses, depreciation, and other applicable tax deductions.

Roles of corporate income tax

Corporate income tax plays several essential roles and holds significance for both the nation and businesses:

  • Contribution to Government budget: Corporate income tax serves as a crucial revenue source for the national budget. Taxes fund the implementation of public policies, infrastructure projects, and the provision of essential public services.
  • Effective management and regulation of the national economy: By adjusting tax rates and related policies, the government can stimulate or control specific industries, fostering balanced and sustainable economic development.
  • Ensuring equity through tax obligations: Businesses are responsible for paying taxes based on their income, ensuring fairness in the tax system and contributing to a more equitable economy.
  • Assessing business efficiency: Classifying and calculating taxes based on income allows for the evaluation of a business’ success and profit-generating capability.
