The SS tax rate is scheduled for a statutory increase effective October1, 2010 from 6% to 7%. Why is the 1% increase necessary?
The statutory SS tax rate increase would increase the employee’s share of contributions from 6% to 7% of taxable wages and would also increase the employer’s matching contribution by the same rate, for a total of 2% increase in the combined SS tax rate (14%). This increase is actuarially determined to balance the benefit formula.
