Individual Income Tax Returns, Preliminary Data, 2007

摘要

These data represent estimates of income and tax items based on a sample of individual income tax returns filed between January and late September of a given processing year. These returns are then weighted to represent a full year of taxpayer reporting. In general, some of the returns processed during the remainder of the year may have somewhat different characteristics compared to these earlier ones. Therefore, these preliminary data are best utilized by comparisons made to the preliminary estimates from the prior year. When available, the estimates from the Complete Year Data should be used in place of the preliminary data.
