The seal of the competent tax authority. The electronic work of tax filing for external payments is an important measure to facilitate taxpayers, serve taxpayers, and effectively reduce the tax burden on enterprises and the pressure on tax service departments. After successful filing, the taxpayer needs to print the "Tax Registration Form for External Payments in Service Trade and Other Items", stamp the seal of the competent tax authority on the "Signature or Seal of the Filing Person", and then go to the bank with this form and relevant materials to pay foreign exchange.
