What counts as work under Thai law?

Thailand has a broad definition of “work.” It is not limited to paid employment or receiving a salary in Thailand. Depending on the circumstances, activities carried out for a business or employer, such as signing a document, may be regarded as work, even if you are paid overseas or receive no payment at all.

What We See In Practice

I'm not employed by a Thai company and I'm not being paid in Thailand, so I'm not working, right?

WHAT CLIENTS ASK US

Not necessarily. Many foreigners assume that only local employment counts as work, but Thai law focuses on what you are actually doing rather than where your salary comes from or who pays you. This misunderstanding is one of the most common reasons people unintentionally breach Thailand’s employment rules.

Thailand’s definition of work goes well beyond having a job with a Thai employer. Depending on the circumstances, activities such as managing a business, providing professional services, attending client meetings, supervising staff, negotiating contracts, or carrying out work for an overseas employer may all require the appropriate work authorisation. Whether an activity is considered work depends on the nature of what you are doing, not simply where you are paid.

Section 5 of Thailand’s Working of Aliens law defines “work” very broadly as the use of physical effort or knowledge in an occupation or job, with or without payment. Only activities specifically exempted by the Minister are excluded. Because of this broad definition, anyone doing more than purely passive activities in Thailand should consider obtaining a Work Permit. In practice, enforcement focuses more on whether a person is properly authorised to work at all, rather than the exact details of each task once permission is granted.
