Hi there, jimh3.

We can record prior tax payments in Quickbooks Online so the tax notification is removed. Let me show you how:

1. From the left panel, select the Taxes tab then Payroll Settings.
2. Click on the Enter Prior Tax History link,
3. Choose Add Payment.
4. Select  tax type and liability period (the period that the taxes accrued) then click enter
    Payment due
   Check Number (optional)
   Note (optional)
   Tax item amounts.
5. Once done, click OK.

For more information, you can check this article on how to record a prior tax payment in QBO: Recording prior tax payments

If you have any other questions with the process,
