Legal analysis: Private hospitals belong to private for-profit medical and health units, and according to the provisional regulations on business tax, they belong to the scope of business tax payment. Although it is stipulated that medical services are exempt from business tax, medical institutions are under the jurisdiction of the local taxation bureau, where invoices are collected and purchased.

Therefore, if private hospitals don't invoice, they should complain to the local tax.
