Earlier in the week, the IRS Statistics of Income Division published the “First-Time Release of Tax Year 2006 Individual Income Tax Return Statistics by Cumulative Percentiles Based on Income Size and State” report that you can download in Microsoft Excel format here.
According to the report, “the first annual IRS release of tax year 2006 individual income tax return statistics by selected descending cumulative percentiles classified by state is now available. This table shows statistics on income and tax by cumulative percentiles based on numbers of returns filed for each state and the District of Columbia. The information includes distributions of AGI and total income tax by descending cumulative percentiles of returns for the top 1%, 5%, 10%, 25%, and 50% of returns with positive amounts of AGI. The table was compiled from the master file of tax year 2006 income tax returns that were filed and processed by the IRS during calendar year 2007. Returns for prior years processed during calendar year 2007 were not included in this tabulation. Tax year 2006 is the only year that percentile data by state are available. Similar data for tax year 2007 are planned for release in the spring 2009.”
