How often do Social Security tax rates change?

Answer by  Kurt (4579)

Social Security tax rates change when Congress votes on making a change. The rates changed for 2011 where employees had a 2 percent decrease in withholdings but employers remained unchanged.

Social Security tax rates are set as a percentage of your income. The percentage that the government takes from each pay check is currently 7.65 percent. If you are self employed, it is twice that. However, the upper limit of income on which you pay Social Security tax is indexed each year based on inflation.
