Revenue Tax SBT


Specific business tax (SBT) is imposed on certain types of businesses whose value added is difficult to define such as banking, finance, credit foncier, life insurance, pawnshops, and real estate. Such businesses are considered to be outside the VAT system and therefore are not subject to VAT (source: the Thailand Revenue Department).

Revenue Tax: VAT


Value Added Tax (VAT) has been implemented in Thailand since 1992 replacing Business Tax (BT). The VAT is currently imposed at a rate of 7%, with a few exceptions, such as small entrepreneur whose annual turnover is less than 1.8 million baht. A company must register for Value Added Tax if it is expected that its gross income will exceed 1.8 million baht per annum or within 30 days of the date they reach 1,8 million baht in sales (check for possible changes). Companies registered for VAT must file VAT returns and pay tax (if any) to the local district office monthly, within 15 days from the end of the month which the VAT is to be accounted for (source Thailand revenue department).

VAT Exemption Threshold in Thailand

Businesses with an annual turnover of less than 1.8 million Thai Baht are exempt from mandatory VAT registration.

  • No need to collect or remit VAT if revenue stays below the threshold.
  • Voluntary VAT registration is allowed.
  • If turnover exceeds THB 1.8 million, registration is required within 30 days.
