To fix a payroll error in QuickBooks Desktop, start by updating QuickBooks Desktop and the latest payroll tax table, as outdated versions are a common cause of payroll issues. Verify that your payroll subscription is active, the service key is correct, and your system date and time are accurate. Check your internet connection, then run the QuickBooks Tool Hub to repair payroll and program-related problems. Also, make sure QuickBooks services are running properly and that firewall or antivirus software is not blocking payroll updates. If the payroll error continues, call +1 (302) 205-4658 for expert QuickBooks payroll support and a quick resolution.
