Clear card: 1. Select the remote tax copy module, click the tax return status button, and click OK after seeing the prompt that remote tax copy can be performed. 2. Click on the tax return result. If the tax return result is successful and the error number is 0000, it means that the anti-counterfeiting tax-controlled billing data is successfully compared with the electronic declaration, and the card can be cleared. 3. Click the card clearing operation button, prompting that after the card clearing operation is successful, check the strain of tax return data items in status query.
