You can't. Because the real estate agent does not have the right to help with the personal tax payment certificate, if you want to apply for the personal tax payment certificate, you need to bring your personal ID card to the tax service hall and print it on the self-service tax machine, and the personal tax payment certificate must be handled by yourself, and you can't do it on your behalf, so the Hefei real estate agent can't help with the personal tax payment certificate.
