Related to my last piece on the 2011 US payroll tax mess created by last minute changes implemented in the last days of 2010, this alert for Microsoft Dynamics GP customers is simple to understand.  Simple to fix.  But what a mess if you don't get it.

If you rely on the January payroll tax liability calculations in Dynamics GP, you will be incorrect. You must manually calculate the liability until the 2011 Round 2 Payroll Tax Code is available and applied in late January.
