Dear, the seal on the financial statement of the electronic tax bureau is only a visual display of the CA certificate. The absence of a seal does not affect the submission of electronic certificates and the legal effect of certificates. Whether the "electronic seal" is applied in the "electronic tax return", if it is not applied, the seal will not be displayed. If you apply for an electronic seal, you need the telecommunications department to make and review the seal, and the general cycle takes 5 working days. After approval, click "Update Seal" on the declaration page to update the seal to the smart terminal. However, the legal effect of electronic certificate lies in CA certificate, and the seal is only an intuitive display of CA certificate. The absence of a seal does not affect the submission of electronic certificates and the legal effect of certificates.
