Tax monitoring. A registered company must operate in principle, and it can be revoked according to law if it does not operate for a long time, but it is rarely revoked in practice. If the company does not operate for a long time after registration, it will be subject to tax monitoring and the approved taxes will be cancelled. You can't declare zero turnover, but the stamp duty of paid-in capital should be declared at 0.5% of paid-in capital at one time. If a registered company does not handle tax returns, it should report to the tax bureau. No matter whether it is opened or not, tax returns must be made every month, and tax returns can be made according to the local minimum industrial and commercial tax standards.
