Individual Income Tax Rates and Shares Data Snapshots 2009 PDF 2008 PDF The Individual Income Tax Rates and Tax Shares bulletin article and associated statistical tables describe the income and tax distribution, both in terms of percentiles and marginal tax rates, of all tax returns for the selected year. Beginning with Tax Year 2014, the information on tax rates can be found in Publication 1304, Individual Income Tax Returns Complete Report. Statistical Tables The tables are available as Microsoft Excel® files. A free Excel viewer is available for download, if needed. The tables are grouped into the following categories: All Individual Income Tax Returns Excluding Dependents Classified by Tax Percentile - Early release data that presents statistics on AGI and income tax by cumulative percentiles of returns excluding dependents. Tables show distributions of AGI for each tax year and can be used to make comparisons across cumulative percentile classes within each year. Table 3 presents data for major income, deduction, and tax credits reported across different cumulative percentiles. Returns with Modified Taxable Income (MTI) - MTI is a term used to describe "income subject to tax", the actual base on which tax is computed. For current-year returns, MTI is identical to taxable income. For prior-year returns, taxable income is modified to equal an amount necessary to generate the tax actually shown on these returns using current-year rates. Returns with Positive Adjusted Gross Income(AGI) - AGI is "total income", as defined by the tax code, less "statutory adjustments". Returns with Positive "1979 Income Concept" Income - The "1979 Income Concept" was developed to provide a more uniform measure of income across tax years. By including the same income and deduction items in each year's income calculation and using only items available on Federal individual income tax returns, the definition is consistent throughout the base years and can be used for future years to compare income by including only income components common to all years.

The data in these tables are based on a modified universe of tax returns. In particular, all individual income tax returns except returns of dependents are now used in the computation whereas previous releases were based on only returns with positive AGI. This change was the result of feedback and recommendations made by users of these statistics who encouraged SOI to assess the utility of the information. The data in the improved tables shown here, while more accurate for the dollar amounts shown are still very similar in terms of percentages when compared to the data produced under the previous methodology.
