1. Before the tax authorities complete the review, we can cancel the tax refund application in the mobile app.

2. If the tax authorities have submitted an application to the state treasury after examination and approval, they cannot cancel the application and need to go through the formalities of correction and declaration.

3. We set the upper limit of revocable times in the mobile personal income tax APP. If the number of revocable tax refund applications exceeds 5 times, the system will automatically revoke the network revocation authority, and you need to go to the tax service hall to handle the follow-up matters.
