Idaho’s public pension investment earnings climbed from $373.2 million in 2023 to $447.8 million in 2024 using information from the U.S. Census Bureau’s Annual Survey of Public Pensions.
The U.S. Census Bureau’s Annual Survey of Public Pensions encompasses defined-benefit pension plans sponsored by recognized government authorities, with members who are public employees paid from public funds. In this survey, local governments include counties, municipalities, townships, school districts and special districts.
The survey compiles figures for revenues, expenses, financial assets, and membership among these pension plans, and specialized questionnaires may gather further data, such as liabilities.
Not every respondent supplies full details for all questions, resulting in variable response rates that can limit the financial details shown in some tables.
By 2025, nine states lack a broad-based personal income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. Some differences apply to New Hampshire and Washington in terms of investment or capital gains taxation.
According to the report, Idaho included data from six pension plans—three state-run and three operated locally. Membership totaled 190,209, with 190,084 in state systems and 125 in local plans.
