The 4th Quintile. Those in the bottom 20 to 40 percent of all households had an average income of $25,955 and paid income taxes of $1,273 compared to combined (employer/employee) employment taxes of $3,972. That brought their total taxes to $5,245 or 18.8 percent of income.
The Middle Quintile. Those in the middle 40 to 60 percent of all households had an average income of $40,637 and paid income taxes of $3,611. Their combined employment tax payments, $6,218, were still nearly twice as much as their income tax. Their total tax payment, $9,829, absorbed 22.6 percent of their income.
The Near-Affluent Quintile. In the 60th to 80th percentile, the average income was $59,457. In that bracket the average income tax payment was $5,636 and the combined employment tax was $9,096. The total tax burden was 23.0 percent. In other words, the tax burden hardly changes even though income rises by about 50 percent.
