County Clerk

Pete Duncan Macoupin County Clerk
Tax Extensions

The County Clerk is responsible for calculating property tax rates for all local governments, or taxing districts, in Macoupin County that authorize the collection of revenue through real estate taxes.

How tax rates are calculated:

• The Macoupin County Assessor's office establishes property valuations.
• Taxing districts file their levy requests with the County Clerk’s office.
• To produce the revenue requested, the County Clerk uses the levy to determine the tax amount to be "extended" against all properties located within the boundaries of the taxing district.
• The County Clerk determines the rate needed per $100 of taxable value to generate the requested revenue, based on the value of all taxable property within the district boundaries.

(Note: Limits under Illinois law can restrict the revenue, either through statutory maximum rates for certain purposes and/or through "tax caps," which limit the total amount extended. Extension limits are not applied to funds needed to pay bonds and certain other charges.)
