Federal Revenue Suffers as Taxes Depend on Small Group of High-Income Earners

The one percent pay 41.8 percent of income taxes

What is shocking is the degree to which federal revenues have underperformed even for an underperforming economy; revenues have dropped by 2.7% of GDP since 2007.

Why? A more progressive tax code now leverages the negative impact of slow economic growth. The share of all individual income taxes paid by the top 1% has risen to 41.8% in 2008 from 17.4% in 1980—but almost two-thirds of the income from the top 1% comes from nonwage income, including capital gains, dividends and proprietor's profits.

Individual income taxes as well as corporate taxes are now far more rooted in the shifting sands of volatile business income and capital profits rather than in the terra firma of wage income that stabilizes payroll taxes. From 1960 to 2000, payroll taxes were never lower than in the previous year, individual income taxes dipped only twice, and corporate taxes dropped 11 times. Since 2000, individual income and corporate tax revenues dropped five times, while payroll taxes fell twice. Not only do revenues from individual tax returns drop more often now. They fall more severely, with recent collapses of 14%-20% versus the 3%-5% range before 2000.
