Is there a maximum taxable amount for Medicare, too?

When Medicare started in 1966, the maximum amount of taxable earnings each year was the same for both programs.

Starting in 1991, the Medicare taxable earnings amounts became higher than the Social Security amounts. In 1991, the Medicare maximum was $125,000, in 1992, $130,200 and in 1993, $135,000.

Since 1994, there has been no limit on the taxable earnings for Medicare. You now pay Medicare taxes on all your wages and net income from self-employment.
