SOI Tax Stats - Filing season statistics

Our filing season statistics present data from all Forms 1040 processed by the IRS at three critical points during the year: late May, mid-July, and mid-November.

• The late-May filing season statistics by adjusted gross income (AGI) summarize the data from all individual income tax returns filed with the IRS by late May. These tables primarily reflect income earned in the year preceding the filing year, and reported to the IRS by the April 15 filing deadline. These data exclude taxpayers who requested a 6-month filing extension by filing Form 4868, Application for Automatic Extension of Time To File U.S. Individual Income Tax Return. The data represent approximately 90 percent of all returns that will be processed by the IRS in the calendar year. Because taxpayers who request an extension generally have more complex finances, on average, the data reflect 84 percent of the total AGI and 80 percent of the total tax liability that will be reported for all individual income tax returns filed during the year.
• Statistics from returns processed by mid-July update the data from the late-May filing season statistics. These statistics represent approximately 95 percent of all individual filers, 87 percent of total AGI, and 82 percent of total tax liability.
• Data in the last set of tables, the mid-November filing season statistics by AGI, reflect nearly all individual income tax returns that will be received and processed in the calendar year, including any returns filed by the April 15 deadline and granted a 6-month extension.

These filing season statistics are presented in two sections.

• First section: Expanded tables present data for selected sources of income, deductions, credits, and taxes for returns filed for the prior tax year.
• Second section: Includes distributional data for AGI, income tax after credits, and the share of income from the sale of capital assets for returns filed for the prior tax year and some late-filed returns for earlier tax years.

Distributional data presented for adjusted gross income, income tax after credits and share of income from sales of capital assets

These data have been developed as part of a research program to provide authoritative data for use by researchers that would avoid the inaccuracies that may occur by using incomplete data. The statistics primarily represent income earned in the prior year, but will include some late-filed returns for earlier tax years.

The final column in each table indicates the share of income from the sale of capital assets represented in the income presented. By comparing the data presented in these tables over time, they can be used to develop early estimates of changes in the economy or to update forecasts of economic activity that were developed using older data.
