Understanding the corporate income tax rate is a key question that every manager and accountant needs to know to ensure legal compliance and optimize profits. (According to Article 10) Law on Corporate Income Tax No. 14/2008/QH12 (Amended by Law No. 32/2013/QH13), the current general tax rate is 20%, applicable to most economic entities in Vietnam. Understanding the tax rate helps businesses plan their finances accurately and avoid legal risks during tax audits.
The government also issued many documents such as Circular 78/2014/TT-BTC Or Decree 218/2013/ND-CP to detail the preferential cases. Determining the amount of corporate income tax depends on the business sector, location, and scale of each entity. To gain the most accurate understanding of tax obligations, we invite you to join MAN – Master Accountant Network in analyzing the current regulations in detail below.
What is the corporate income tax rate and what are the current legal regulations?

To answer the question of what the corporate income tax rate is, we need to refer to the currently effective tax laws and regulations. Corporate income tax (CIT) It is a direct tax, levied on the taxable income of a business during the tax period after deducting reasonable expenses.
Current general tax rate
Since January 1st, 2016, as part of the business support roadmap, the standard corporate income tax rate has been officially set. So, what is the specific corporate income tax rate for ordinary companies? The answer is 20%. This rate applies to all businesses that are not eligible for preferential treatment or special tax rates, such as those involved in mineral extraction.
Tax rates for resource exploration, prospecting, and exploitation activities.
For specific industries, the question of what the corporate income tax rate is will have a different answer. Activities related to the search, exploration, and exploitation of oil, gas, and rare resources in Vietnam have tax rates ranging from 32% to 50%. The specific tax rate will depend on the location, exploitation conditions, and characteristics of each project as approved by the Ministry of Finance.
The table below summarizes the tax rates by industry group:
| Applicable objects | Corporate income tax rate | Legal basis |
| General business | 20% | Law No. 32/2013/QH13 |
| Oil and gas exploitation | 32% – 50% | Depending on the mining project |
| Exploiting rare resources (gold, silver, precious stones, etc.) | 40% – 50% | Circular 78/2014/TT-BTC |
Components of taxable income
Knowing the amount of corporate income tax is only the first step; the most important thing is determining the actual amount payable. The basic tax calculation formula is as follows:
|
Corporate income tax payable = Taxable income – Amount allocated to science and technology fund x Tax rate |
Taxable income
Taxable income includes income from the production and sale of goods and services, and other types of income. Other income includes capital gains, real estate transfers, and income from intellectual property rights. Accountants need to accurately classify these income sources to apply the correct corporate income tax rate for each activity.
Deductible and non-deductible expenses
To optimize corporate income tax, accountants need to pay close attention to deductible expenses. According to Article 6 of Circular 78/2014/TT-BTC, deductible expenses must be actually related to production and business activities and have valid invoices and supporting documents. For invoices exceeding 20 million VND, non-cash payment documents are mandatory for recognition.
Corporate income tax incentives – An opportunity to reduce costs.

Many new businesses worry about the amount of corporate income tax they will incur when they start generating profits. In reality, the government has many preferential tax policies and periods of tax exemption and reduction to encourage investment. These policies help businesses reduce financial pressure during their initial development phase.
Preferential tax rates (10% and 17%)
A preferential tax rate of 10% for 15 years applies to projects in particularly disadvantaged areas, economic zones, or high-tech zones. Additionally, a rate of 17% applies to projects in areas with difficult conditions. Therefore, the question of what the corporate income tax rate is will receive a very favorable answer for strategic investors.
Tax exemption and tax reduction incentives
The "2-for-4 tax exemption" or "4-for-9 tax exemption" schemes are extremely important incentives that help businesses accumulate capital. Specifically, businesses are completely exempt from taxes in the early years and receive a 50% tax reduction in the subsequent period. This helps answer the question of what the corporate income tax is in the initial operating period, which is usually 01% tax.
Methods for calculating corporate income tax for micro-enterprises.

For businesses with low revenue, the tax calculation method can be simplified to a percentage of revenue. If this method is applied, do you know what the corporate income tax rate is? This percentage is specifically stipulated for each industry to support businesses that do not meet the requirements for complex accounting records.
According to regulations, the corporate income tax rate on revenue for these organizations is as follows:
- Service: 5%
- Goods trading: 1%
- Other activities: 2%
Things to note when filing corporate income tax returns.

Annually, businesses must file a tax return to accurately determine the amount of corporate income tax payable for the entire fiscal year. The deadline for filing is the last day of the third month following the end of the fiscal year. Late filing may result in unnecessary penalties from the authorities.
Risks arising from misidentifying revenue and expenses.
Without a thorough understanding of regulations, businesses can easily make accounting errors, affecting the amount of corporate income tax they pay. These errors can lead to tax arrears and administrative penalties under Decree 125/2020/ND-CP. Therefore, carefully reviewing all economic transactions is extremely necessary.
The importance of reviewing records before final settlement.
Before filing your tax return, reviewing all invoices and payment documents is a mandatory step. Experts from MAN always recommend that businesses use a review service to know the exact amount of corporate income tax due. This helps ensure a clean record and minimizes risks when a tax audit team comes to work.
