Because the company will file tax returns the next month after registration (for example, a company established in April will not file tax returns in May and file tax returns in June), it is necessary to file tax returns as soon as possible after registration and open a bank account. The specific requirements of each district are different. For example, Haidian requires the company to register in the national tax, and the local tax registration needs to be handled as soon as possible after obtaining the bank account opening permit; Chaoyang requires that the local tax report be made within 10 days, and the national tax report be made after the bank opens an account.
