A tax payment is missing below message is showing but I dont know which tax payment is missing

Hi there, ishti.

Thank you for visiting the QuickBooks Community. I'll be sharing details and troubleshooting steps to make sure that you'll be able to resolve the error message.

Based on the error that you've received, it could be that the scheduled tax payments were not processed due to missing information. That said, you can follow the recommended details from the prompt to fix the issue.

If the issue persists, it's possible that your QuickBooks Desktop (QBDT) data might have been damaged. Thus, causes receiving an unusual error message. I recommend running the  Verify and Rebuild Data Utilities to get this sorted out. The Verify Data utility identifies any potential data damage issues that might've caused unusual behavior. While the Rebuild Data utility repairs damaged data in your company file. Before this, you'll have to secure a backup copy of your company file.

To Verify data:

1. Go to the File menu.
2. Scroll down to Utilities.
3. Select Verify Data.
4. Click OK.

To Rebuild Data:

1. Go back to the File menu.
2. Choose Utilities.
3. Select Rebuild Data.
4. Click on OK when you get the message Rebuild has completed.
