Back to top American Statistical Association Conference 2009 Title: Analysis of the Distribution of Income and Taxes Using Cross Section and Panel Data from Individual Tax Returns, 1979-2007 PDF Authors: Michael Strudler, Tom Petska, Young Lim and Lori Hentz, SOI, IRS, and Ryan Petska, Quantitative Economics and Statistics, Ernst and Young LLP Abstract: This paper is the eighth in a series examining trends in the distribution of individual incomes and tax burdens based on a consistent and comprehensive measure of income derived from individual income tax returns. The previous papers demonstrated that the shares of income accounted for by the highest income-size classes clearly have increased over time, and also demonstrated the superiority of our comprehensive and consistent income measure, the 1979 Retrospective Income Concept, particularly in periods of tax reform. This paper, will continue the analysis of individual income and tax distributions, adding for eight years (1999 - 2006) Social Security and Medicare taxes to this analysis and using panel data (for 1999 – 2006). 2008 Title: Statistics from Individual Income Tax Returns: Populations, Samples, and Processing of Individual Income Tax Returns at Statistics of Income Authors: Michael E. Weber and David P. Paris and Peter J. Sailer Abstract: Statistics from Individual Income Tax Returns have been produced by the Statistics of Income Division since 1917. This paper discusses the statistics generated from the yearly filing of Individual Income tax returns from the early 1960s to the present. It traces changes made to the yearly sampling plan from a single cross section used for national estimates to the current configuration which includes a cross section for national estimates, a Continuous Work History Sample panel, multiple stratified high income cohort panels, and a an expanded cross section sample for state level estimates, as well a nonfiler sample. The paper will also explain how these samples are processed from raw administrative data into perfected data as well provide definitions of SOI terminology and a description of the various products derived from these samples. Title: SOI/IRS Sales of Capital Assets Sample Redesign for Tax Year 2007 Authors: Yan K. Liu and Michael Strudler and Jana Scali and Janette Wilson Abstract: The Statistics of Income (SOI) of the IRS developed a stratified sample of individual returns to study the form 1040 Sales of Capital Assets (SOCA) in tax year 1999. It was a cross-sectional sample from the population of all individual returns of tax year 1999. Because of high processing cost of SOCA returns, there has been no other SOCA cross-sectional sample ever since. However, the 1999 SOCA cross-sectional sample is outdated as there have been many economic changes that impact capital gains. Therefore, it is decided to start a new SOCA cross-sectional sample for tax year 2007. This paper discusses how the new sample is designed, including determining stratum boundaries, allocating sample sizes to strata, and balancing the cost and precision. The Neyman allocation is used and the information on cost estimate and variance estimate is obtained from the related SOI's data sources. Title: Attrition in the Tax Years 1999—2005 Individual Income Tax Return Panel Authors: Victoria Bryant, Statistics of Income, IRS Abstract: Policy research is increasingly being done on panel data; attrition can undermine validity and misrepresent results of many policy analyses. Using the Individual Income Tax Return Panel for Tax Years 1999-2005, this paper will examine panel attrition. It tests the randomness of attrition and evaluates the implications of such results. It assesses the observed rate to determine the predictability over time. Finally, it will present several tabular representation problems hindering analysis. 2007 Title: Measuring Disclosure Risk and an Examination of the Possibilities of Using Synthetic Data in the Individual Income Tax Return Public Use File PDF Authors: Sonya Vartivarian, John L. Czajka, and Michael Weber Abstract: Each year, the Statistics of Income (SOI) Division of the Internal Revenue Service (IRS) draws a sample of individual and sole proprietorship tax returns, abstracts and edits a large number of data items, and prepares a microdatabase that the Treasury Department and the Congress use for tax policy analysis. 2006 Title: Analysis of the Distributions of Income, Taxes, and Payroll Taxes via Cross Section and Panel Data, 1979-2004 PDF Authors: Michael Strudler, Tom Petska, and Lori Hentz, Statistics of Income, IRS, and Ryan Petska, Quantitative Economics and Statistics, Ernst and Young LLP Abstract: Different approaches have been used to measure the distribution of individual income over time. Survey data have been compiled with comprehensive enumeration, but underreporting of incomes, inadequate coverage at the highest income levels and omission of a key income type jeopardize the validity of results. Administrative records, such as income tax returns, may be less susceptible to underreporting of income but exclude certain nontaxable income types and can be inconsistent in periods when the tax law has been changed. Title: Social Security Taxes, Social Security Benefits, and Social Security Benefits Taxation, 2003 PDF Authors: Peter Sailer, Kevin Pierce, and Evgenia Lomize, Statistics of Income, IRS Abstract: For most of its 90-year existence, the Statistics of Income (SOI) Division of the Internal Revenue Service and its predecessor organizations have used data provided by taxpayers on Forms 1040 to fulfill the legal mandate to produce statistics on the operation of the individual income tax system. It was not until Tax Year 1989 that SOI started using the Information Returns Master File (IRMF), which contains electronic documents filed by the payers of income to individuals, to add further details to the tax return information. Title: The Tax Year 1999-2003 Individual Income Tax Return Panel: A First Look at the Data PDF Authors: Michael E.

A previous ASA paper explained the history and development of this panel so that only a brief review of the panel’s history and design will be provided in this paper. 2005 Title: Measuring Nonsampling Error in the Statistics of Income Individual Tax Return Study PDF Authors: Jana Scali, Valerie Testa, Maureen Kahr, and Michael Strudler, Statistics of Income, IRS Abstract: The purpose of this paper is to estimate a component of nonsampling error in the SOI Individual Study. The data from the quality review process is used for this purpose. Title: The 1999 Individual Income Tax Return Edited Panel PDF Authors: Michael E. Weber and Victoria L.

Title: Trends in 401(k) and IRA Contribution Activity, 1999-2002--Results from a Panel of Matched Tax Returns and Information Documents PDF Authors: Peter Sailer and Victoria L. Bryant, Statistics of Income, IRS and Sara Holden, Investment Company Institute Abstract: By combining individual tax returns (Form 1040) and information returns (such as Forms W-2 and 5498) in one panel database, the Statistics of Income (SOI) Division has made it possible to study trends in contributions by individual taxpayers over time to Individual Retirement Arrangements (IRA’s), as well as the participation in other types of retirement plans. 2004 Title: Further Analysis of the Distribution of Income and Taxes, 1979-2002 PDF Authors: Michael Strudler and Tom Petska, Statistics of Income, IRS, and Ryan Petska, Quantitative Economics and Statistics, Ernst and Young LLP.

In addition, the method and data used to measure disclosure risk and information loss as well as results and recommendations for further research are also discussed.

Title: The IRS Population Count: An Update PDF Authors: Peter Sailer and Michael Weber; Statistics of Income, IRS. November 1998 Abstract: In a paper presented at the 1993 Annual Meetings of the American Statistical Association, the authors presented the results of their first attempt to use administrative records available at the Internal Revenue Service (IRS) to count the population of the United States. That paper noted a major problem in the use of IRS administrative records was the presence in files of information documents for deceased individuals.
