Comparing Taxation Vietnam Thailand

In the realm of international business and investment, a comprehensive understanding of the taxation systems in Vietnam and Thailand is indispensable. As both countries vie for global attention, the distinctions in their tax systems, tax rates, and tax structures carry immense weight in the choices made by businesses and investors. From corporate income tax to VAT and other levies, the variances in tax incentives and structures can significantly impact financial strategies and overall operations. Navigating these taxation differences is imperative for making well-informed decisions that can pave the way for long-term success in Southeast Asia.

Taxation Structures and Rates in Vietnam

Vietnam's taxation structure is a multifaceted framework essential for businesses and investors operating in the country. This structure comprises several key elements, with Corporate Income Tax (CIT), Personal Income Tax (PIT), and Value Added Tax (VAT) being the most prominent.

Value Added Tax (VAT) in Vietnam

  • 0% VAT: Applied to goods and services like exported goods, goods sold to non-tariff areas, export processing companies, and international transportation services, this rate plays a significant role in facilitating international trade.
  • 5% VAT: This is typically applied to essential goods and services, making it more accessible for the general population. It covers items such as clean water, teaching aids, and medical equipment.
  • 10% VAT: Representing the standard rate, this applies to activities not specified as exempt from VAT or subject to a lower rate.

Personal Income Tax (PIT) in Vietnam

Vietnam's PIT system is progressive, with rates ranging from 5% to 35%. Recent changes in the tax landscape focus on combating tax evasion and regulating Transfer Pricing Decrees, impacting how multinational corporations interact with local entities.

Corporate Income Tax (CIT) in Vietnam

Regarding CIT, the standard rate is 20%. However, the oil and gas sector faces rates between 32% and 50%, while businesses involved in prospecting and mineral resource exploitation deal with CIT rates of 40% or 50%. These variations depend on project location and conditions.

Tax incentives in Vietnam

Vietnam offers several tax incentives aimed at attracting foreign investment and fostering economic growth. These incentives can encompass tax holidays, preferential tax rates, and exemptions, and their availability depends on factors such as location, industry, and project size. Various sectors, including education, healthcare, high technology, and environmental protection, are encouraged by the Vietnamese government to benefit from these incentives. Specific social sectors, like education and healthcare, can enjoy the 10% rate for the entire duration of their projects.

Moreover, Decision 29/2021, in effect since October 6, 2021, provides guidance on special investment incentives applicable to qualified Research and Development (R&D) and large investment projects outlined in the Law on Investment. The CIT incentives for these projects differ based on specific criteria. The most favorable package includes a preferential tax rate of 5% for 37 years, six years of tax exemption, and a 50% CIT reduction for the following 13 years. Land and water rental fees may also be exempted or reduced for a specified period.

Taxation System in Thailand

Value Added Tax (VAT) in Thailand

VAT, a cornerstone of the Thai tax system, is primarily levied at a standard rate of 10%. Nevertheless, Thailand also implements a 0% VAT rate for specific items and services, such as those associated with exports and international transportation, along with transactions involving government agencies and state enterprises under foreign aid programs.

Personal Income Tax (PIT) in Thailand

PIT in Thailand adheres to a progressive structure, meaning that tax rates fluctuate in accordance with individuals' income levels. For residents, the rates span from 5% to 35%, while non-residents are subject to flat rates, typically set at 15%.

Corporate Income Tax (CIT) in Thailand

CIT in Thailand is typically assessed at a flat rate of 20% on net profits for most businesses. Nevertheless, specific sectors, especially those under investment promotion schemes like the Board of Investment (BOI), may have varied rates. Businesses and partnerships with capital below 5 million Thai baht and revenue under 30 million Thai baht are subject to specific rates: 0% for up to 300,000 Thai baht, 15% for revenue between 300,001 and 3 million Thai baht, and 20% for earnings exceeding 3 million Thai baht.

Beyond these core taxes, Thailand also imposes Specific Business Tax (SBT), Stamp Duty, and Excise Tax. SBT is relevant to specific businesses and activities, while Stamp Duty is levied on various documents like contracts and licenses. Excise Tax pertains to specific goods and services, such as alcoholic beverages, tobacco, and petroleum.

Tax incentives in Thailand

In the realm of tax incentives, Thailand offers a range of provisions designed to foster foreign investment and stimulate economic growth. These incentives encompass exemptions and reductions in taxes, such as import duties and corporate income tax, with various incentives linked to investment size, location, and promoted activities. For instance, investors may encounter import duty exemptions for items used in research and development (R&D), reductions in corporate income tax rates, and even exclusions of dividends from promoted enterprises from taxable income during specific periods. Double deductions, deductions of infrastructure installation or construction costs, and more incentivize businesses and investors, making Thailand a compelling destination for those seeking tax advantages and investment opportunities.

Key Differences and Comparisons: Vietnam vs. Thailand Taxation

Vietnam’s Taxation Landscape

Vietnam's taxation system exhibits a dynamic landscape with several layers of taxes, including Corporate Income Tax (CIT), Personal Income Tax (PIT), Value Added Tax (VAT), and various other taxes. The structure is complex yet navigable, offering several tax incentives aimed at fostering foreign investment and business growth. However, businesses often encounter certain challenges such as occasional bureaucratic inefficiencies and the need for a thorough understanding of the regulatory landscape.

Thailand’s Taxation Environment

On the other hand, Thailand's taxation framework also encompasses essential elements such as Corporate Income Tax (CIT), Personal Income Tax (PIT), Value Added Tax (VAT), and additional taxes like Specific Business Tax (SBT) and Stamp Duty. Thailand's tax system boasts a wide range of tax incentives that serve as powerful catalysts for attracting foreign investment. However, businesses may face certain challenges, including a potentially more complex tax structure and the need for comprehensive compliance with local tax regulations.

Factors for Consideration

Considering the implications of taxation in both countries is crucial when evaluating the best locations for investment and business setup. While Vietnam offers a more straightforward tax system in some respects, Thailand provides an array of attractive incentives for businesses, making both countries compelling options for various types of investors. It's essential to carefully assess the tax implications in each country, weighing the challenges and opportunities they present, to make well-informed decisions about the best fit for your business operations.
