First of all, after the external information exchange system obtains the registration information of individual industrial and commercial households with "two certificates integration" transmitted by the industrial and commercial department, it will be automatically sorted to the county (district) tax authorities according to the production and business address (marked by the administrative division of the production and business address). In the core collection and management system, if the county (district) tax authorities confirm that the distribution is wrong, they will be returned to the city (prefecture) tax authorities for manual distribution; If the provincial tax authorities cannot be directly assigned to the county (district) tax authorities, they will be assigned to the city (prefecture) tax authorities, and the city (prefecture) tax authorities will manually assign them to the county (district) tax authorities. Provincial tax authorities can explore the rules of automatic sorting by themselves to reduce the workload of manual sorting.
Secondly, when taxpayers handle tax-related matters for the first time, the competent tax authorities obtain the registration form information of individual industrial and commercial households through the external information exchange system and confirm other tax management information.
Finally, the information that self-employed individuals need to carry includes a copy of business license, official seal, special seal for invoices, special seal for finance, legal person seal, basic bank account opening permit, legal person ID card, etc.
