FF445: Summary of Latest Federal Income Tax Data (EXCEL)
The Internal Revenue Service has recently released new data on individual income taxes for calendar year 2012, showing the number of taxpayers, adjusted gross income, and income tax shares by income percentiles.
[1]
The data demonstrates that the U.S. individual income tax continues to be very progressive, borne mainly by the highest income earners.
- In 2012, 136.1 million taxpayers reported earning $9.04 trillion in adjusted gross income and paid $1.1 trillion in income taxes.
- All income groups increased their income and taxes paid over the previous year.
- The top 1 percent of taxpayers earned their largest share of income since 2007 at 21.9 percent of total AGI and paid their largest share of the income tax burden since the same year at 38.1 percent of total income taxes.
- In 2012, the top 50 percent of all taxpayers (68 million filers) paid 97.2 percent of all income taxes while the bottom 50 percent paid the remaining 2.8 percent.
- The top 1 percent (1.3 million filers) paid a greater share of income taxes (38.1 percent) than the bottom 90 percent (122.4 million filers) combined (29.8 percent).
- The top 1 percent of taxpayers paid a higher effective income tax rate than any other group at 22.8 percent, which is nearly 7 times higher than taxpayers in the bottom 50 percent (3.28 percent).
Taxpayers Reported $9.04 Trillion in Adjusted Gross Income and Paid $1.19 Trillion in Income Taxes in 2012
Taxpayers reported $9.04 trillion in adjusted gross income (AGI) on 136.1 million tax returns in 2012. This represents $725 billion in additional income over 2011 on 500,000 fewer tax returns. While the majority of the income gain went to the top 5 percent of taxpayers (those making $175,817 or more), every income group experienced an increase in income in 2012. Due to the increase in incomes, taxes paid increased by $142 billion to $1.185 trillion in 2012. Taxes paid increased for all income groups.
The share of income earned by the top 1 percent increased to 21.9 percent of total AGI, the highest level since the peak year of 2007 (22.9 percent of total AGI). The share of the income tax burden for the top 1 percent increased to 38.1 percent from 35.1 percent in 2011, also the highest level since the peak in 2007 (39.8 percent).
Top 50 Percent of All Taxpayers Paid 97.2 Percent of All Federal Income Taxes; Top 1 Percent Paid 38.1 Percent; and Bottom 90 Percent Paid 29.7 Percent of All Federal Income Taxes
Figure 1 shows the distribution of AGI and income taxes paid by income percentiles in 2012. In 2012, the bottom 50 percent of taxpayers (those with AGIs below $36,055) earned 11.1 percent of total AGI. This group of taxpayers paid approximately $33 billion in taxes, or 2.8 percent of all income taxes in 2012.
In contrast, the top 1 percent of all taxpayers (taxpayers with AGIs of $434,682 and above), earned 21.9 percent of all AGI in 2012, but paid 38.1 percent of all federal income taxes.
Combined, the top 1 percent of taxpayers (those with AGIs above $434,682) accounted for more income taxes paid than the bottom 90 percent (those with AGIs below $125,195) combined. In 2012, the top 1 percent of taxpayers paid $451 billion in income taxes, or 38.1 percent of all income taxes while the bottom 90 percent paid $353 billion in income taxes, or 29.8 percent of all income taxes paid.
The Top 1 Percent’s Effective Tax Rate Is Nearly Seven Times Higher than the Bottom 50 percent’s
The 2012 IRS data shows that taxpayers with higher incomes pay much higher effective income tax rates than lower-income taxpayers.
The bottom 50 percent of taxpayers (taxpayers with AGIs under $36,055) faced an average effective income tax rate of 3.3 percent. As taxpayer AGI increases, the IRS data shows that average income tax rates rise. For example, taxpayers with AGIs between the 10th and 5th percentile ($125,195 and $175,817) pay an average effective rate of 13.3 percent—four times the rate paid by those in the bottom 50 percent.
The top 1 percent of taxpayers (AGI of $434,682 and higher) paid the highest effective income tax rate at 22.8 percent, 6.9 times the rate faced by the bottom 50 percent of taxpayers. The top 1 percent’s average effective tax rate for 2012 of 22.8 percent was slightly lower than that of 2011 (23.5 percent).
Taxpayers at the very top of the income distribution, the top 0.1 percent, which includes taxpayers with incomes over $2.2 million, actually paid a slightly lower income tax rate than the top 1 percent (21.7 percent versus 22.8 percent). This is due to the fact that very high income taxpayers are more likely to report a greater share of their income as taxable capital gains income. This leads to a slightly lower effective tax rate because capital gains and dividends income faces a lower top income tax rate (23.8 percent) than wage and business income (39.6 percent). It is important to note, however, that capital gains taxes at the individual level are the second layer of tax after the corporate income tax (which is 35 percent).
