Social security and Medicare taxes have different rates and only the social security tax has a wage base limit. The wage base limit is the maximum wage subject to the tax for the year. Determine the amount of withholding for social security and Medicare taxes by multiplying each payment by the employee tax rate. There are no withholding allowances for social security and Medicare taxes.
Your FICA tax is comprised of contributions to two benefit programs, the Old-Age, Survivors, and Disability Insurance, or OASDI, and the Hospital Insurance known as Medicare A. Employers and employees pay the same FICA contribution rates. Unlike Social Security taxes, there is no upper limit to the Medicare tax.
