Let's make sure that you're able to find the report, deb7007.

It's possible that the Sales Tax function was turned off. This can be the reason why the Sales Tax Liability report is not showing up. Follow these steps on how to turn it back on:

1. Go to the Edit menu and select Preferences.
2. Select Sales Tax in the left-hand menu.
3. Proceed to the Company Preferences tab.
4. Select Yes in the Do you charge sales tax section.
5. Click OK. 

Once done, go back to the Report Center and check if you can already see the Sales Tax Liability report.
