Updated April 13, 2010: I don't think my original labels were clear so I tried to fix it with new labels and I reorder the graphs. This is a new infographic illustrating the marginal federal tax rate applied to different salaries. It shows the difference between the combined rate levied on an employee (Income + SSN + Medicare marginal tax rate) and the additional rate levied on the employer, i.e. the payroll tax (SSN + Medicare tax) I am using the same examples that I created in the previous six graphics looking at the average tax rate.
