A tax registration certificate is a registration certificate issued by a taxpayer engaged in production or business operations when applying for tax registration with the competent tax authorities in the place where the production or business operations or tax obligations occur. Taxpayers must hold tax registration certificates when opening bank accounts, applying for tax reduction, exemption, tax refund and other matters, except those that do not need to be issued with tax registration certificates according to regulations. Taxpayers should publicly hang the original tax registration certificate in their production, business operations or office places and accept the inspection by the tax authorities.
