Later, due to the tax-sharing reform, the tax bureau was divided into the national tax bureau and the local tax bureau, which were referred to as the "national tax bureau" and the "local tax bureau" respectively. For example, Henan Provincial State Taxation Bureau and Henan Provincial Local Taxation Bureau are referred to as "Henan Provincial State Taxation Bureau" and "Henan Provincial Local Taxation Bureau" respectively.
The State Taxation Bureau system is directly under the vertical management of State Taxation Administration of The People's Republic of China, People's Republic of China (PRC), and is called the "national tax system", which is responsible for the tax collection and management of the central revenue and the income enjoyed by the central and local governments; The local taxation bureau system implements vertical management below the provincial level, that is, the provincial local taxation bureau is managed by the provincial government, and the city and county local taxation bureaus are vertically managed by the provincial local taxation bureau, which is referred to as the "local taxation system" and is responsible for tax collection and management of provincial and below income.
Since 20 18, the tax collection and management system has been reformed, and the State Taxation Bureau and the Local Taxation Bureau have merged to become today's "tax bureau", with the full name of "People's Republic of China (PRC) State Taxation Bureau ×××××××× Tax Bureau". For example, People's Republic of China (PRC) State Taxation Administration of The People's Republic of China Henan Provincial Taxation Bureau, People's Republic of China (PRC) State Taxation Administration of The People's Republic of China Luoyang Taxation Bureau.
