Due to the limited resources in ancient times, especially in the Shang Dynasty, the heavy tax system caused people to complain and waste money, so there was the later Shang Yang reform. By the Western Zhou Dynasty, it had been changed to the well-field system, with grain as the mainstay, land leasing, labor and taxation as the mainstay. Subsequent dynasties mainly used the combination of these two tax methods as the main source of national finance. After Wei Chu and Qin State, Shang Yang gave up the private ownership of land because of the reform fee, which opened the fundamental thought of attaching importance to agriculture and restraining commerce in ancient China. Impose a heavy tax system on business. These three basic tax sources run through all ancient tax systems.
After the establishment of a more unified imperial dynasty in Qin and Han dynasties, the tax payment and collection of the financial system became more specific and personalized, such as poll tax, property tax, income tax and consumption tax. Unlike before, it is based on surnames. But at this time, a very good idea was established, that is, the state finance and royal property were separated and managed independently.
However, during the Wei, Jin, Southern and Northern Dynasties, due to the greed and management negligence of the monarch at the beginning, the royal property was confused with the national finance, and the national treasury was the private treasury of the royal family. Therefore, the reign of Wei, Jin, Southern and Northern Dynasties was very short, and it was also because a good financial system was not established. During the Sui and Tang Dynasties, the financial system was further decentralized, and it was no longer completely centralized, but was independently collected from local finances and then unified. In the Song, Ming and Qing Dynasties, there was a very systematic fiscal regulation and tax collection classification for all localities and provinces, specifically for every industry, class and family. The national treasury is divided into general treasury, sub-treasury and sub-treasury.
