FILING OF BUDGET AND APPROPRIATION ORDINANCES (35 ILCS 200/18-50)

The governing authority of each taxing district shall file with the County Clerk within 30 days of their adoption a certified copy of its appropriation and budget ordinances or resolutions, as well as an estimate, certified by its chief fiscal officer, of revenues, by source, anticipated to be received by the taxing district in the following fiscal year.

If the governing authority fails to file the required documents, the County Clerk shall have the authority, after giving timely notice of the failure of the taxing district, to refuse to extend the tax levy until the documents are filed (Consult your State’s Attorney before any refusal).

In determining the amount of maximum tax authorized to be levied by any statute of this State, the assessed valuation of the current year of property as assessed and reviewed by the local assessment officials or the Department, and as equalized or confirmed by the Department, shall be used.
