In order to support business households in this important transition period, the banking sector has proactively coordinated with the Tax Department in implementing digital transformation solutions, providing digital financial solutions and long-term support for small traders and businesses. In addition, it needs to support small traders in terms of online tax declaration and payment via banks; implement digital payment solutions and identity accounts; provide preferential loan packages for small traders; builde a comprehensive digital ecosystem for financial management and arrange a team of staff to provide support all around o’clock to answer questions for business households. Eliminating lump-sum tax is an inevitable step to ensure tax fairness and promote healthy private economic development in the spirit of Resolution 68 of the Politburo on private economic development. In particular, the participation of commercial banks, the providers of electronic invoice software, sales software and payment intermediary organizations is a key factor in helping business households access technology, improve management capacity and promote noncash payments.
