The payroll tax in the United States is a flat-rate tax on earnings in the labor market, up to a ceiling. Most Americans receive most of their income from labor-market earnings, and the ceiling is much higher than the average wage earner makes in a year. Thus the payroll tax is approximately proportional over most of the income range. However, above a certain amount (which was $106,800 in 2011), the marginal rate of payroll tax decreases dramatically. As a result, what can we say about the payroll tax for those who earn more than the ceiling?

-
It is progressive.

It is proportional
-
It is regressive
