Work and business

Work legally in Thailand: start with the right questions.

Work, visas, company ownership and professional restrictions are different subjects. This page helps you identify the official checks needed before acting; it is not legal, immigration or tax advice.

Read the information correctly

Law, practice and recommendation are not the same thing.

Law

Statutes, ministerial notifications and official conditions define the legal framework. Their effective date and scope matter.

Practice

Application documents, appointments and administrative expectations can vary by authority, location and case.

Recommendation

Prepare early, retain written evidence and obtain professional advice before spending money or performing work.

Before you move

A safer preparation sequence.

Do not treat a social-media checklist as an authorization. Start with the activity you will actually perform and the entity that will receive the work.

  1. 1Describe the work, client/employer, place, duration and payment flow in writing.
  2. 2Check whether the occupation is restricted and whether a licence or regulated qualification is required.
  3. 3Confirm the appropriate immigration and work-authorisation route before starting any work.
  4. 4Check company, tax, social-security and sector-specific obligations with official bodies and qualified advisers.

Work permission: the core rule

The Department of Employment and BOI explain that foreign nationals generally need authorization before working. The permitted role, employer/entity and conditions matter; do not assume that a tourist stay, exemption or a company shareholding is enough.

  • Use the Department of Employment’s current e-WorkPermit and guidance.
  • Keep your work description aligned with the authorization obtained.
  • Check changes of employer, role, location or company before acting.
  • Treat regulated professions as a separate licence question.

Restricted occupations

Thailand’s Ministry of Labour publishes prohibited and conditionally restricted occupations for foreigners. The list is detailed and can change: consult the current official notification rather than relying on summaries.

Company and investment

A company is not a shortcut to work authorization.

Foreign ownership, the business activity, licensing and the right to work are related but separate. The Foreign Business Act and sector rules can apply even where a company is registered.

Foreign Business Act

Check whether the intended activity falls within a restricted list, needs a Foreign Business License/Certificate or benefits from a lawful exemption.

BOI pathways

Eligible investment-promoted projects can follow dedicated BOI procedures. Promotion is not automatic and conditions remain project-specific.

Visas and permits

Non-immigrant visa categories, work authorization and a company’s filings must be coherent. Always verify current official requirements.

Remote work and online activity

“Remote” does not by itself settle Thai immigration, labour, tax or licensing questions. The facts — where you are, what you do, for whom and how you are paid — matter. Obtain advice before relying on informal labels.

Watch for training and visa scams

Be cautious of guarantees of visas, work permits, nominee structures, licences or jobs. Verify the provider’s legal identity, authority and written terms directly with official sources before paying.

Questions people ask

Practical orientation, not a personal ruling.

Can I work because I have a visa?

Not automatically. Entry permission and permission to work are separate questions. Confirm both against your exact activity.

Can I open a company and work immediately?

No general shortcut exists. Company registration, foreign-business rules, immigration and work authorization must each be satisfied.

Is there one Thai-employee-to-foreigner ratio?

No universal rule should be assumed. Requirements can depend on the route, employer, capital, sector and incentive scheme. Confirm the current official rule for your case.

Are digital or remote roles automatically allowed?

No. Online work still needs a fact-specific immigration, labour, tax and regulatory assessment.

Where do I apply?

Use the current Department of Employment e-WorkPermit process or the applicable BOI/One Stop route; official links are below.
