No. In accordance with the Measures of the People's Republic of China for Invoice Management, all units and individuals engaged in production and business activities shall obtain invoices from the payee when paying for goods, services and other business activities. If the developer fails to issue an invoice truthfully, the buyer can report to the local competent tax authority with the purchase contract, the bank mortgage contract (if there is a loan), the developer's receipt or down payment invoice. The Measures for the Administration of Invoices stipulates that if a developer fails to issue an invoice as required, the tax authority may order it to make corrections and impose a penalty of less than 10000 yuan. The invoice for house purchase is very important, but some developers do not issue invoices to house buyers in order to avoid taxes. If the developer delays in issuing the purchase invoice, the buyer can reasonably ask them for it, because there is legal support for you. Therefore, your own purchase invoice and other purchase procedures must be well kept.
