There may be some restrictions in the system of the property management company, so it is impossible to automatically bring the unified social credit code into the invoice, so the taxpayer's name can only be filled in manually. This does not affect the legality and availability of invoices. As long as the taxpayer's information is correct, the invoice can still be used as a tax deduction certificate. The invoice for the maintenance fund shall be issued by the property management company. According to tax regulations, invoices issued by property management companies as taxpayers need to include taxpayer identification numbers (unified social credit codes or taxpayer identification numbers).
