Will cooperate. First of all, it is obvious that the fourth phase of the golden tax has not arrived. At present, there is no official document to determine the specific online time of the fourth phase of Golden Tax. Everyone's conclusion of "going online at the end of this year" is based on the speech made by Wang Jun, director of People's Republic of China (PRC) State Taxation Administration of The People's Republic of China, at the Third Belt and Road Tax Administration Cooperation Forum on September 22nd. "The China tax authorities are developing the fourth phase of the golden tax (smart tax), which will be basically developed by the end of this year." Although the official has not yet decided, the specific time should not be too bad.
