Under the coordination of industry and commerce, taxation and other departments, Wanbailin District Administrative Service Center merged the first floor windows of 12 (industrial and commercial window) and 13 (tax window) into "new enterprise service window" to realize "one-stop service". Through integration, the industrial and commercial department completed the registration of enterprise establishment within 3 days. The tax authorities will reduce the time for new enterprises to register new households, authenticate their real names and apply for invoices for the first time to less than 1 day.
