Why not this year? South Dakota governments with newer filings show figures from the South Dakota Department of Legislative Audit and the South Dakota Department of Education (for 2025). Each other figure is the newest year the U.S. Census Bureau has published for that government, so the years differ and are not the current year. Most governments post their current budget on their own website.

How these figures are counted. South Dakota county and city figures are the annual financial reports each government filed with the South Dakota Department of Legislative Audit for the calendar year shown, and school district figures are the annual financial reports filed with the South Dakota Department of Education for the 2024-25 school year. Borrowing, transfers between a government's own funds and money held for others are not counted, and debt payments include principal as well as interest.

How a ZIP is matched. A ZIP code is not a government boundary, so we match it to the cities, counties and school districts that overlap it, using Census Bureau geography. Where a ZIP crosses several, each one is shown with its share of the ZIP. Each government's money covers its own operations only; the others listed here are separate.

Latest recorded year. The year differs by government: each block shows the newest fiscal year on file. A Census survey year covers fiscal years ending July 1 of the year before through June 30 of that year.
