Possible Workaround on Sage 100 Advanced and Premium:

Process Tax Calculation on the Server

• Select this check box to process the Payroll tax calculation program on your server instead of on a workstation when someone is processing payroll. Clear this check box if you want to process the calculation on the workstation.
• An internet connection is required to run the program. If you select this check box, and the server cannot reach the online tax calculation engine when a user is running Payroll Tax Calculation, the system will automatically try to run the program on the workstation instead.
• The tax calculation program typically runs faster on a server than on a workstation.
• This field is available only for Sage 100 Advanced and Premium.
