Question 1

Where does municipal finance data come from?

Accepted Answer

Municipal finance data comes from the Illinois Comptroller's Annual Financial Reports (AFR). Every municipality in Illinois is required to file an annual report detailing revenue, expenditures, fund balances, and debt. These reports are public record.

Question 2

What are the main revenue sources for a municipality?

Accepted Answer

Most Illinois municipalities rely on property taxes, sales taxes, state income tax sharing, utility taxes, permits and fees, and fines. The mix varies by town. Some municipalities also receive revenue from TIF districts, enterprise funds (water/sewer), and intergovernmental transfers.

Question 3

What is a General Fund and why does it matter?

Accepted Answer

The General Fund is the municipality's primary operating fund. It covers core services like police, fire, public works, and administration. A healthy General Fund balance (typically 25-50% of annual expenditures) indicates the town can handle unexpected expenses without raising taxes or cutting services.

Question 4

How current is this financial data?

Accepted Answer

The Illinois Comptroller's data warehouse typically lags 6-12 months behind the current fiscal year. The most recent year with complete data is usually one to two fiscal years prior. Data is refreshed monthly as new filings are processed.
