How to calculate preferential corporate income tax
Preferential corporate income tax (CIT) is calculated based on the taxable income of the enterprise, applying preferential tax rates and tax exemption and reduction periods according to regulations. The calculation must comply with the following steps:
Determining taxable income
Taxable income is the total revenue from production, business and service activities, minus deductible expenses, losses carried forward to the next period and tax exemptions according to the law. Enterprises need to ensure that expenses are fully accounted for and have legal documents.
Determine preferential tax rates
Preferential tax rates apply depending on industry, location and project type. For example:
- Preferential tax rate 10% for high-tech projects or investment in high-tech zones.
- Preferential tax rate of 10–15% for clean agriculture, renewable energy or R&D projects.
Apply tax exemption and reduction period
For businesses to fully understand the benefits of corporate income tax incentives, they need to understand how to apply tax exemption and reduction periods. This accurately determines the amount of tax payable in each stage of the project, helping to optimize costs, plan finances and effectively take advantage of incentives according to legal regulations.
- During the tax exemption period, enterprises do not have to pay corporate income tax.
- After the tax exemption period, during the period of 50% tax reduction, the enterprise only pays 50% of tax calculated at the preferential tax rate.
Preferential corporate income tax calculation formula
To accurately determine the amount of corporate income tax payable during the incentive period, businesses need to base on the following formula:
|
Corporate income tax payable = Taxable income x Preferential tax rate x Preferential time coefficient |
Illustrative example of corporate income tax incentives
ABC Company operates in the field of software production and invests in building a research center in the high-tech park of Ho Chi Minh City. The project will start operating from June 2025, with a total investment capital of VND50 billion and is expected to generate revenue of VND5 billion per year.
Enterprises in the information technology and software production industries should enjoy corporate income tax incentives according to their industries. At the same time, the project is implemented in a high-tech zone, where enterprises are entitled to preferential tax rates of 10% and tax exemption and reduction policies according to the law. The incentive period is tax exemption for the first 2 years and tax reduction of 50% for the next 4 years from the date the project comes into operation.

In years 1-2, the taxable income of the enterprise is 5 billion VND per year. Due to tax exemption during this period, the corporate income tax payable is 0 VND. In years 3-6, the enterprise only has to pay 50% of tax calculated at the preferential tax rate, equivalent to 250 million VND/year. From year 7 onwards, when the tax exemption and reduction period ends, the corporate income tax payable is 500 million VND/year at the standard preferential tax rate of 10%.
Thanks to the preferential corporate income tax policy, ABC enterprise saved 1 billion VND in taxes in the first 6 years. This money can be reinvested in expanding production, developing new products and improving human resources capacity, thereby increasing competitiveness in the market.
Understanding the conditions of the industry, location and duration of the incentive is the key for businesses to maximize tax benefits. At the same time, preparing complete documents and transparent accounting is a prerequisite for the tax authority to accept the incentive, helping to reduce costs and increase investment efficiency.
Cases not eligible for corporate income tax incentives
In order for businesses to apply corporate income tax incentives in accordance with regulations and avoid the risk of being overpaid, it is very important to clearly understand the cases that are not eligible for incentives. This section will summarize the conditions and situations that businesses will not be eligible for tax exemption or reduction, helping to plan investments and manage taxes effectively.
Enterprises operating outside priority industries
Enterprises not on the list of priority industries will not enjoy CIT incentives. This includes industries not on the list of high technology, research and development (R&D), software production, clean agriculture, renewable energy or special industries that the State encourages investment in.
Enterprises investing in non-preferential areas
Enterprises implementing projects in normal areas, not in disadvantaged areas, high-tech zones, special economic zones or preferential industrial zones, will not be entitled to preferential tax rates. In this case, enterprises must pay tax according to the standard rate 20% without any tax exemption or reduction in any period.
Failure to meet requirements for records, documents and accounting
Enterprises that do not ensure transparent records and documents or have incomplete accounting will not be eligible for incentives. For example, if the project has not yet come into actual operation, has not generated taxable revenue, or the records proving the incentive conditions are incomplete, the tax authority has the right to refuse to apply tax exemption or reduction.
Abuse of tax incentives or false declarations
Enterprises that abuse tax incentives, falsely declare their business lines, locations, or falsify documents to enjoy lower tax rates than prescribed will be removed from the list of preferential beneficiaries. At the same time, enterprises may be subject to additional tax collection and fines according to the law.
Benefits of taking advantage of corporate income tax incentives
Taking advantage of corporate income tax incentives directly benefits businesses by reducing tax costs, thereby increasing working capital and reinvestment capacity. The amount saved through tax exemptions and reductions can be used to expand production, upgrade technology, train staff or develop new products, helping businesses improve their competitiveness in the market.
In addition to financial benefits, tax incentives also help businesses optimize their investment strategies. Knowing in advance the tax rate to be paid and the duration of the incentives, businesses can plan long-term projects, allocate capital effectively and reduce financial risks. This is especially important for high-tech, R&D or renewable energy projects, which often require large capital investments and long payback periods.

Corporate income tax incentives also help businesses increase their attractiveness to investors and partners. Businesses that effectively utilize incentive policies will have transparent financial reports and optimal operating costs, thereby enhancing their reputation and ability to mobilize capital. At the same time, properly applying incentive regulations also helps businesses avoid legal risks, avoid tax arrears or penalties for violations.
Finally, the use of CIT incentives also supports local economic development. When businesses invest in disadvantaged areas, high-tech zones or priority industries, they not only save on taxes but also contribute to job creation, improve product quality and promote sustainable development of the community and economy.

Future trends in corporate income tax incentive policies
In the coming years, Vietnam is expected to increase corporate income tax incentives for businesses operating in the high-tech and green economy sectors. Sectors such as artificial intelligence (AI), semiconductors, renewable energy and research and development (R&D) will enjoy a preferential tax rate of 10% for 15 years, with tax exemption for the first 4 years and a tax reduction of 50% for the next 9 years. This is an effort to encourage technological innovation and sustainable development through preferential corporate income tax policies.
In addition, Vietnam has applied the global minimum tax rate of 15% to multinational corporations with revenue of over 800 million USD from 2024, to comply with international commitments and limit the transfer of profits abroad. This policy also creates a fair competitive environment for domestic enterprises, helping to optimize the benefits from corporate income tax incentives.
Project-based corporate income tax incentives are also being reformed, allowing new or expanded investment projects to enjoy incentives even if they were not previously eligible for incentives. This opens up opportunities for businesses to transform their business models, expand production, and take advantage of favorable corporate income tax incentives.
Increasing transparency and tax management is also an important trend. Enterprises need to fully comply with regulations on financial reporting, documents and contracts to ensure their rights and avoid legal risks, while helping tax authorities effectively control preferential corporate income tax policies.
Finally, Vietnam is establishing financial support funds for strategic investment projects, focusing on infrastructure, human resource training and technology transfer, especially in the fields of AI, semiconductors and R&D. These supports help businesses optimize capital resources, improve competitiveness and promote sustainable economic development, while making the most of the issued corporate income tax incentives.
