This is Tamara from Intuit QuickBooks Desktop Payroll responding to your post regarding the employee social security rate for 2012.  The employee rate of 6.2% was released in payroll update 21201 on 12/15/2011 because that was the rate for 2012 as published by the IRS in Notice 1036.     

Since the release of 21201, the Temporary Payroll Tax Cut Continuation Act of 2011 was signed into law on 12/23/2011. 

The tax tables were being updated to incorporate the change for the employee rate remaining at 4.2% for the first two months (January and February) of tax year 2012. The change is incorporated in payroll update 21202 that released today.
