Self-employed people who apply for the UK in 2020 will go to the industrial and commercial window. Legal persons and ticket buyers bring their ID cards to the tax hall for industrial and commercial registration, then go to Baiwang Jin Fu or Golden Tax Company to buy, and return to the hall for writing and issuing. The two people authenticate the electronic tax bureau with their real names, verify the types and uses of invoices, and then buy tickets at the self-service machine. British tax is levied on self-service machines.

Individual industrial and commercial households need to hold a business license, an ID card of the agent, and an impression of the special seal for invoices made according to the style specified by the competent tax authorities in the State Council to go through the invoice purchase procedures with the competent tax authorities.
