The Revenue Department of Thailand was founded on the 2nd September 1915 by King Rama VI, following on from King Rama V's visions to establish countrywide infrastructure, and to provide a revenue collection platform in order for Thailand to remain aligned internationally.

Taxation is the main source of government's revenue. A large part of tax collection comes from three main agencies under the Ministry of Finance. These are the Revenue Department, the Excise Department, and the Customs Department - which collectively account for about 85-90% of the government's revenue. The Revenue Department itself collects more than half of the total tax collection.

Main objectives

  • To collect all taxes efficiently at an appropriate level, at the lowest compliance cost to the Revenue Department and to taxpayers.
  • To assist in the development of the economy through tax initiatives, which will enable Thailand to remain competitive among economic counterparts.
  • To instil an ethics of voluntary tax compliance, and to pursue effective measures of reprimanding tax evaders.
  • To administer the tax system with the principles of honesty, efficiency and fairness.
