I'm here to help ensure your Sales Tax Liability report and pay sales tax window will match in QuickBooks Online (QBO).
Ideally, the pay sales tax window or Sales Tax Center and the Sales Tax Liability report will get the same amount when both features calculate sales taxes. To check if the browser is already full of frequently accessed page resources (cache and cookies) causing this unusual response, let's sign in to your QBO using a private browser (incognito).
Here's how:
Press Ctrl + Shift + N (Google Chrome).
Ctrl + Shift + P (Firefox).
Control + Option + P (Safari).
If everything looks good, return to your default browser and perform a clear cache to refresh the system. However, if the issue persists, try using other supported browsers.
