Thank you for taking the time to reach out to us here in the Community. I'd be glad to help check why your QuickBooks does not update tax information.
To update tax information or calculate taxes correctly, you'll need to ensure that you have a payroll service/subscription. If you have the payroll service active and taxes won't update, you will need to verify that your payroll tax table is updated.
To download the payroll tax table update:
Click on Employees at the top menu bar.
Select on Get Payroll Updates.
Put a check in the Download Entire Update checkbox.
Click on Update.
A window appears when the download is complete.
