Hello there, FD11.

QuickBooks Online (QBO) automatically creates two default accounts when setting up sales tax. These are the Suspense account and the Payable account. Recording the sales tax payment moves the amount from Suspense to the bank account as how it works in the system. You can use this link in recording your sales tax payment in the Sales Tax Center. 

If your suspense account still shows an amount after enter the tax payment and performed the browser troubleshooting steps, you can be reaching out to us so we can investigate further. Let me share again the steps on how to contact us:
