Top 3 Outsource Accounting Services in Thailand

Posted by Hailey on February 24th, 2021


Thailand is one of the premier business hubs in the world, attracting millions of international business travelers each year. Taking advantage of its location in the center of the Association of Southeast Asian Nations, the Thai government has designed its laws to make it easy for foreign-owned businesses to open in Thailand. But while opening a business is easy, Thailand still has very complicated tax and accounting laws and protocols, increasing the need for foreign-owned businesses to use a outsource Thai accounting service.

Because Thailand is home to hundreds of branch or representative offices of multinational companies, there are many great accounting services in Thailand to choose from. A good accounting service will have proper knowledge of the different taxes applicable to the different types of foreign-owned businesses, produce timely reports and books, and understand the processes involved in reporting information to the revenue department.

With so many great options to choose from, we’ve put together our top 3 accounting services in Thailand that will help any foreign-owned business navigate the difficult Thai accounting and tax systems.
