There are a number of reasons why QuickBooks Payroll could not be operating, including out-of-date software, faulty files, or problems with internet access. Make sure QuickBooks is up to date in order to begin fixing it. To manually update the payroll if the software is already up to date, navigate to the \"Employees\" menu and choose \"Get Payroll Updates.\" To make sure QuickBooks can reach the necessary servers, check your firewall settings and internet connection if the issue continues.
