Individual income taxes are based on net personal income and taxes imposed on such income as dividends, interest, and income from intangibles.
In addition to detailed tax revenue data from each state, the Quarterly Summary of State and Local Government Tax Revenue includes an estimate of state and local government tax revenue at a national level.
The Census Bureau cautions that it sets the tax classifications among the survey categories, and they may differ from the classifications set by the state governments.
Overall, Colorado collected $3.6 billion in combined tax revenues in the first quarter of 2025, a decrease from the $5.3 billion collected in the previous quarter.
During 2024, the U.S. government collected a total of $4.92 trillion in revenue. Individual income taxes were the biggest contributor, generating $2.4 trillion, nearly half of all revenue collected.
