The data was obtained by Wirepoints through a Freedom of Information Act request to the Illinois State Board of Education.
Illinois has enacted a law that changes the amount of debt school districts can issue. According to an analysis by Chapman, the new rules permit school districts to borrow more money than previously allowed. At the same time, the law modifies limits on property tax extensions that fund this debt. As a result, if districts take on more debt, local property taxes could increase to cover the additional costs.
The Illinois State Board of Education’s budget for fiscal year 2026 will increase from nearly $10.8 billion to about $11.2 billion. This includes a $307 million boost for K–12 schools, marking the smallest annual increase since 2020.
The agency has paused about $50 million in funding previously allocated through the Evidence-Based Funding formula for the Property Tax Relief Grant while reviewing its impact on local tax relief. Officials say the pause could affect the timing and amount of property tax relief available to taxpayers.
The annual reporting aims to increase transparency and accountability around school debt. Future reports will include 15 years of historical data, allowing residents to track long-term financial trends.
