Individual Statistics of Income Reports

About the Reports

The Colorado Individual Statistics of Income (SOI) report is a collection of data sourced from federal and state individual income tax returns filed by full-year Colorado residents. The reports include data on income, taxes, age, location, and more. Colorado’s Individual SOI report complements the Individual SOI report published by the Internal Revenue Service (IRS), and serves as a useful tool for researchers and policy makers.

Beginning with tax year 2021, state and federal return statistics are reported separately. State data is available earlier (two years after each tax year ends), while federal data follows later (three to four years after each tax year ends). Reports prior to 2021 used single combined datasets that merged federal and state return data, thereby delaying the release of state data due to its dependence on federal data.

For tax years 2021 and later, state income tax credit data are available on the Income Tax Credits webpage and state income tax subtraction data are available on the Income Tax Subtractions webpage.

Methodology:

The State Return Data Tables summarizes data from state income tax returns filed by full-year Colorado residents for income tax year 2023. Income tax year is defined by the year that a taxing period began. Most individuals file using a calendar year, but a small number of filers use a fiscal year. Returns filed by part-year residents and nonresidents are not included in this report.

Data for 2023 Colorado income tax returns were extracted on August 21, 2025, reflecting a snapshot of the returns at that time. The data often reflects initial submissions and may not include subsequent corrections or amended returns. All tax return data is subject to change.

To ensure taxpayer confidentiality, disclosure analysis was performed on each variable for each table. The Department only releases aggregated state data if no single taxpayer represents over 80% of the total and if there are at least three taxpayers per group. Suppressed values due to confidentiality are marked "NR" in the data tables.

Methodology:

The Federal Return Data Tables summarize income and tax data from a merged dataset of state and federal tax returns filed by full-year Colorado residents for tax year 2021. Returns filed by part-year residents and nonresidents are not included in this report. Colorado returns are excluded if their federal income information does not align with their federal return. The Federal Return Data is a subset of the State Return Data.

Income tax year is defined by the year that a taxing period began. Most individuals file using a calendar year, but a small number of filers use a fiscal year.

Data for 2021 federal and Colorado income tax returns were extracted on August 24, 2023, reflecting a snapshot of the returns at that time. The data often reflects initial submissions and may not include subsequent corrections or amended returns. All tax return data is subject to change.

To ensure taxpayer confidentiality, disclosure analysis was performed on each variable for each table. Federal guidelines require a minimum of 10 taxpayers per group for state-level information release. Additionally, the Department only releases aggregated data if no single taxpayer represents over 80% of the total. Suppressed values due to confidentiality are marked "NR" in the data tables.

Enhancements and Changes Since the Previous Report:

Added three new tables:
- Table 14 - Business Income by Industry
- Table 19 - Selected Federal Tax Credits by Size of Federal AGI
- Table 26 - Colorado Income Tax Prepayments by Size of Federal AGI
Significant changes made to three tables:
- Table 17 - This table no longer summarizes personal exemptions (see 2017 Table 18), but now includes qualified business income deductions. These modifications were made due to federal tax return changes.
- Table 20 and Table 21 - Five Colorado regions are now summarized instead of the 14 planning regions summarized in previous SOI reports.
Formatting changes:
- All values are now rounded to the nearest dollar.
- Previous reports rounded summed totals to the nearest thousand, which will affect comparisons to prior year data.

Narrative and Charts:

2018 Individual SOI Narrative and Charts (PDF)
- Includes an introduction, highlights, charts, and methodology
- Features insights into major changes that started tax year 2018 due to the federal Tax Cuts and Jobs Act of 2017 (TCJA) (NEW!)
- TCJA Overview and Impacts section includes charts and tables that compare 2018 and 2017 to demonstrate the impacts the TCJA had on Colorado income tax filers (NEW!)

Data Tables:

The 2018 Individual SOI tables summarize key statistics on income and tax data by income group, including the number of returns, federal adjusted gross income (AGI), federal taxable income, Colorado gross tax, Colorado net tax, and federal tax. The aggregate data is split into various groupings, such as filing status, age, and location. Four tables (Tables 7, 8, 11, and 12) break out return data by age group. Information on the composition of Colorado households can be found by examining filing statuses (Tables 3, 4, 9, and 10). Detailed data on sources of income, business income by industry, and adjustments to income are reported in Tables 13, 14, and 15. Reductions from federal income such as standard, itemized, and qualified business income deductions are presented in Tables 16, 17, and 18. Selected federal tax credits are summarized in table 19. Geographic (county or region) data is presented in Tables 20 through 23. Data specific to the calculation of Colorado taxable income and tax due — including additions, subtractions, tax prepayments, tax credits, and voluntary contributions — are the focus of Tables 24 through 28.
