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.
I get the impression that many Americans believe Medicare is financed like Social Security. They know that a portion of payroll taxes goes to Social Security and a portion goes to Medicare. So they conclude workers are paying for Medicare benefits the same way they are paying for Social Security benefits. That isnât remotely true, as new data from the Congressional Budget Office demonstrate. In 2010, payroll taxes covered a little more than a third of Medicareâs costs. Beneficiary premiums (and some other earmarked receipts) covered about a seventh.
