  • Corporate Income Tax
  • Value Added Taxes (or Specific Business Taxes)
  • Stamp Duty
  • Personal Income Tax

In addition, the Thailand Customs Department is responsible for collecting import and export duties and The Excise Department collects excise tax.

Property tax and municipal tax are collected by the Thai local authorities.

Personal Income Tax (PIT): is a direct tax levied on personal income.

This includes income of an individual, an ordinary partnership, a non-juristic body of person, a deceased person or an undivided estate. In general, a person liable for Personal Income Tax must compute personal tax liability, file a tax return and pay tax accordingly, if any, on a calendar year basis.

Corporate Income Tax (CIT): is a direct tax levied on a juristic company or partnership that has been established under Thai or foreign law and conducts business in Thailand or derives specific types of income from Thailand.

The term “juristic company or partnership” includes: a limited company, a limited partnership or a registered ordinary partnership incorporated under Thai or foreign law as well as an association and a foundation engaged in business producing revenue.

The term also includes any joint venture, trading or profit-seeking activity operated by a foreign government or its agency or other juristic body incorporated under a foreign law.

Thai Tax Filing And Payments: Thai or foreign entities which are conducting business in Thailand must submit tax returns and payments twice a year.
