Jiujiang Clearance was an important circulation hub in the Yangtze River Basin, and it was also where grain had to go through from the middle and upper reaches of the Yangtse to Jiangsu and Zhejiang Provinces. The tax revenue of this Clearance was from 300, 000 to 400, 000 taels in the early Qianlong Period and reached the highest level of 600, 000 to 700, 000 taels in the late Qianlong Period. In the Jiaqing and Daoguang Period it was stable between 500,000 and 600, 000 taels. Although it was lower than that of the late Qianlong Period, it was still far higher than that of the early Qianlong Period. During the 48 tax sessions from Jiaqing's nine years to Daoguang's thirty years, Jiujiang Tax Clearance collected grain and groceries ship tax annually more than 220,000 taels in 39 years, of which 20 years reached 300,000 taels or more. According to the proportion of ship tax paid in silver, it is estimated that the average amount of grain and groceries ship tax in silver is 340, 000~380,000 taels in the late Qianlong Period. During the Jiaqing and Daoguang Period, crop failures occurred frequently North of the Yangtze. When the harvest in Jiangxi and Hunan Provinces was good, a large amount of grain was transported to the stricken areas, and the ship tax paid in silver collected by Jiujiang would be more abundant.
