2. Tax calculation formula

Basic CIT calculation formula

CIT = Taxable Income x Tax Rate

In which:

Taxable income: is the total revenue after deducting allowable expenses as prescribed by the Law on Corporate Income Tax. Includes:

  • Revenue from the production and business of goods and services.
  • Revenue from the transfer of capital, real estate, and land use rights.
  • Interest income from financial investment activities.
  • Other income as prescribed by law. 

Tax rate: The standard CIT rate is 20%. However, there are some cases where a different CIT rate applies, such as: 

  • 32% – 50%: For activities of exploration, exploitation, and mining of oil and other rare minerals in Vietnam. 
  • 10%: For income of enterprises implementing social housing investment and business projects for sale, lease, and hire-purchase.

CIT calculation steps

  2. Identify allowable expenses.
  3. Calculate taxable income: Revenue – Allowable expenses = Taxable income.

Taxable income: 100 billion VND – 80 billion VND = 20 billion VND. 

CIT: 20 billion VND x 20% = 4 billion VND.
