Today I ran into a frustrating issue with Quickbooks. My client was unable to load W-2’s.  The following error was showing up.

An error has occurred.The Payroll Tax Center has experienced an unexpected error. Please exit the Payroll Tax Center and login again in a few minutes. If the problem persists for more than 20 minutes, please contact us.

This error will especially happen if you are running Quickbooks off of a server through RDP. Here is the solution that worked for me.

In Quickbooks > Click Help > Click Internet Connection Setup.

The middle option should be already selected. If it isn’t, select it.

Click Next. > Click Advanced Connection Settings > Click Security Tab > Click Trusted Sites>  Click Sites and Add * > Click Close and OK.

This is what worked for us! I hope it works for you too!
