Payroll updates are essential in QuickBooks Desktop to maintain accurate tax tables and compliance with current regulations. When update verification fails, payroll processing may be interrupted. QuickBooks Error 15222 is a payroll update error that appears when QuickBooks cannot verify the digital signature of an update file or establish a secure connection to the Intuit server. This error commonly occurs during payroll or software update downloads.
