Thailand continues to be one of Southeast Asia’s most attractive destinations for investment and business expansion. With its strategic location, robust infrastructure, and supportive regulatory environment, the country offers significant opportunities for both local and international enterprises. However, navigating the complexities of a foreign market requires more than ambition—it demands insight and preparation. Our Doing Business in Thailand 2025–2026 guide provides a comprehensive overview of the Thai business landscape, covering everything you need to know to establish and grow your operations successfully
Thailand’s newly amended Organic Act on Anti-Corruption (No.2) B.E. 2568 (2025) marks a significant shift in corporate compliance expectations. With expanded whistleblower protections and stricter enforcement mechanisms, companies operating in Thailand must act swiftly to align their internal controls and reporting systems with the new legal landscape.
Thailand stands at a crossroads. Once powered by a young and growing population, the country now faces fewer births, a rising elderly population, and a rapidly shrinking workforce. This is not a distant problem but one already reshaping the economy, society, and future of the nation. The question is not when the demographic crisis will occur, but whether Thailand can adapt quickly enough to survive.
As businesses look ahead to economic recovery in Thailand, some sectors have valuable lessons to learn regarding resilience and overall business strategy.
A share premium is a credited difference in price between the par value, or face value of shares, and the total value a company received for issued shares. You usually record the share premium as capital in the company’s balance sheet. Thus, you do not register the share premium in the company’s revenue and show it in the profit and loss account.
For many businesses, Thailand’s tax and legal infrastructure can seem dauntingly complex. In addition, finding the right tax and legal advice could also be challenging. Given that existing regulations can provide government officers with broad interpretative discretion, businesses must constantly keep themselves abreast of the latest compliance requirements and practices. There is no “one-size fits all” solution or approach to optimise tax savings and legal compliance. Each business is unique in its requirements and circumstances. The effective advisor must thoroughly understand the client’s business and objectives and be aligned with the client on the key priorities, financial capacity, real world commercial limitations, and risk appetite. Furthermore, in the course of obtaining tax and legal advice, businesses often feel the experience wanting. Lawyers, tax advisors, and accountants seem to speak in coded language and are removed from the commercial realities faced by the clients. Professional opinions and recommendations often seem complicated and impracticable. At Grant Thornton in Thailand, we understand the need for high-quality professional services that are tailored to each client’s unique requirements. We strive to provide clients with professional services that leverage our international and local expertise while maintaining approachability. This approach aligns with our core principles of collaboration and respect – the key pillars of our CLEARR values which form the basis of our client-centric approach to delivering services. Quality with a personal touch We strive to provide personalised advice to businesses of all sizes and across a broad spectrum of industries. At Grant Thornton, our partners and senior professionals are accessible to our clients, irrespective of the size and nature of the assignment. This involvement ensures that our clients’ needs are thoroughly understood by our team at all levels, and that our deliverables meet the client’s expectations and requirements. A relationship-led approach We believe in that our relationship with clients should not be transactional. Rather, the relationship should be founded upon trust and professionalism. At Grant Thornton, we strive to understand our clients’ businesses, industries, strengths, and also relative weaknesses in order to develop the appropriate solutions and advice for our clients. We take pride in the long-term professional relationships that we cultivate with clients – often spanning years or even decades. Two kinds of synergy We believe in harnessing the synergy of people and technology to deliver exceptional services. We have invested heavily in training our people and developing a collaborative culture within our firm. This enables us to avoid complex chains of communication, and streamline our decision-making process. We strive to extend this collaborative culture to our clients, thereby allowing us to work in tandem and effectively with our clients. Furthermore, recognizing that we are living an age where technology can be harvested to improve efficiency and the quality of deliverables, we routinely assist our clients in exploring and adopting automation technologies to address their needs.

Because no two problems are identical, a one-size-fits-all service is not the ideal way out. Many issues can be adequately addressed only through carefully tailored solutions, adapted to the client’s own pain points. We find that these types of “out-of-the-box” services tend to exceed client expectations, while also remaining sensitive to their budgetary concerns. To illustrate how we guide our clients towards success, we share with you two different case studies, each beginning with its own set of problems.
Outsourcing lets businesses focus on their core operations, while letting specialists help with other responsibilities. Here we show how this approach can lead to major business improvements.
