Peter Sailer and Kurt Gurka, Statistics of Income, IRS, and Sarah Holden, Investment Company Institute. November 2003.

With nearly $4.0 trillion invested in IRAs and 401(k) plans at year-end 2003, these retirement savings vehicles represent a significant component of Americans’ financial security. Taxpayers holding IRAs and

An Analysis of the Distribution of Individual Income and Taxes, 1979–2001
Michael Strudler and Tom Petska, Statistics of Income, IRS, and Ryan Petska, Quantitative Economics and Statistics, Ernst and Young LLP. December 2003.

The paper contains a summary of the measure of individual income derived as a “retrospective concept” from individual income tax returns, results of the analysis of time series data, and conclusions with examination of Gini coefficients computed from these data. It is the fifth 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. In this paper, the analysis of individual income and tax distributions is continued, adding for 3 years (1979, 1989, and 1999) social security and Medicare taxes to this analysis.

Comparing Scoring Systems From Cluster Analysis and Discriminant Analysis Using Random Samples
William Wong and Chih-Chin Ho, Statistics of Income, IRS. December 2003.

Currently, the Internal Revenue Service (IRS) calculates a scoring formula for each tax return anduses it as one criterion to determine which returns to audit. The IRS periodically updates this formula from a stratified random audit sample. In 1988, such an audit sample was selected. The sample was used to derive a new scoring formula. This score is one of the criteria used to determine whom to audit.
