It may be due to the banking system, such as overtime communication when returning to the national treasury. Exit the transaction page and reapply for the transaction you want after confirming that the transaction is not completed. Generally speaking, after tax declaration, the system will automatically jump to the tax (fee) interface. If not, you can also enter the "I want to pay tax"-"declare tax payment" interface, check the details of the tax to be paid, and then choose the corresponding method to pay tax. If the communication with the national treasury is overtime and the transaction processing fails due to the banking system, you can check the payment status in I want to query-payment information, and then conduct a single transaction processing in I want to pay taxes-declare tax payment-tripartite agreement payment exception handling/bank card payment exception handling. After successful processing, you can enter from the to-do list again and pay taxes again. If you still can't deduct the money after processing, please go to the window of the tax service hall and don't handle the same business again in the electronic tax bureau.
