Proposed Tax Year 2010 Forms and Schedules Full Document PDF in .pdf format (a free Adobe Acrobat reader is available, if needed) This document contains the federal tax forms, schedules and information documents that the Statistics of Income (SOI) Division of the IRS has selected for its Tax Year (TY) 2010 program. Returns for TY 2010 are filed primarily during calendar year 2011, although returns for fiscal-year filers or filers for whom filing extensions have been granted may not be received by the IRS until calendar year 2012. Consequently, summary data for TY 2010 will be made available to the public during calendar years 2012 and 2013. This publication is organized in three parts: Individual Statistics Branch studies include data related to the Form 1040 individual income tax return series, as well as data on sales of capital assets and SOI’s program that connects income tax returns with information documents filed by third parties. The Corporation Statistics Branch studies focus on data collected from the Form 1120 series and SOI’s partnership program. Special Studies Branch programs include data collected for estate and gift taxes, tax-exempt organizations, and tax-exempt bonds, as well as information collected for international filers. The specific data items captured for each SOI project are indicated with a red block on facsimiles of the forms and schedules. Forms and schedules that can be filed by different types of taxpayers are repeated in several sections of this document. Specific changes to the data collected for each form and schedule since the TY 2009 studies are summarized at the beginning of each section.
