# 1. Policy Background
In 2017, the State Taxation Administration stated in the 31st issue of the "Guidance on Further Improving the Implementation of Electronic Ordinary Invoices":
"If the purchaser requests a paper ordinary invoice from the taxpayer who issues an electronic ordinary invoice on site, the taxpayer shall provide a free service to print out the e-invoice. Those who refuse to provide a free printing service or paper invoices shall be promptly corrected by the competent national tax authority."
This means that merchants who provide e-invoices are obligated to provide a paper invoice for free if requested by the consumer.
