Statistics of Income Reports

About the Reports

The Colorado Statistics of Income (SOI) is a complement to the IRS’s Statistics of Income with Colorado specific income tax details. The SOI reports tabulate Colorado individual and corporate income tax return data by income tax year and size of income. These reports show a variety of information from income tax returns.

The data used in the Individual SOI reports are drawn from a merged file of state and federal tax returns. The SOI reports for the most current income tax year are published with a three year lag due to the availability and release of federal income tax data. 

We anticipate posting the 2017 SOI reports in early December 2020.
