Most agency institutions will provide follow-up services such as tax registration and invoice application. The specific services can be selected according to the needs of the enterprise. Tax registration includes tax type determination, signing of tripartite agreements, and registration in the individual income tax system, etc. Invoice application covers processes such as invoice type determination, purchase of tax control equipment, and the first invoice collection. In terms of charges, if subsequent tax services are included during the agency registration process, no additional fees may be required. If handled separately, the fees are usually charged by project (for example, 200 to 500 yuan for tax registration and 300 to 800 yuan for invoice application). The specific fees vary depending on the type of enterprise (small-scale taxpayer or general taxpayer) and the complexity of the service. The agency will provide a clear quotation sheet in advance.
