The Revenue Department of Thailand was founded on the 2^nd 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.
