The two Installment Sections at the top of the bill tell you when the first and second installment payments of your taxes are due, and what amount must be paid by that date. Both installments may be paid on or before the due date of the first installment or you may pay each installment on or before the due date shown for that installment on the tax bill.
Mailed payments must be POSTMARKED ON OR BEFORE THE DUE DATE. You may also pay in person at the:

Late payments received without the penalty included will be returned.
Failure to receive a tax bill or receiving it late, for any reason, will not relieve tax payer from paying taxes or late penalties. If you have not received your tax bill or your mailing address has changed, contact the Boone County Treasurer's Office immediately.

The Permanent Property Number, also called the PIN Number is the number that uniquely identifies your property from all others. This is the number that county officials use, rather than a street address or legal address. You should include this number on all tax payments and in all correspondence or communications with the Treasurer, Supervisor of Assessments or County Clerk regarding your property.

State MultiplierA state multiplier is applied to parcels by the State of Illinois to ensure an equitable apportionment or distribution of the tax burden among taxpayers. An equalizer of less than 1.0 lowers your property value, and your tax burden. An equalizer of more than 1.0 increases your property value and tax burden. An equalizer of 1.0 makes no change to your property value or the amount of taxes you will pay.
Return to Sample Tax Bill

Taxable Value
The Taxable Value of your Property, after certain exemptions and equalizers have been applied. This is the amount that the total tax rates will be applied to in determining your taxes.
The total amount of taxes due is the Total Tax Rate times your Taxable Value as listed on your tax bill.
REMEMBER: The Total Tax Rate is a percentage, so move your decimal point two places to the left when multiplying!
FOR EXAMPLE: (using the bill above)
Total Tax Rate X Taxable Value = $ Amount Taxes Due
.0076463 x $29,712.00 = $2,271.88 Due.
Return to Sample Tax Bill

TAX RATE
Total of all tax rates levied by various taxing districts on your property. The rate is per $100.00 valuation - in other words a percentage. Another way to figure it is to divide your Taxable Value by 100, then multiply by the tax rate. (No need to move any decimal points using this method.)
EXAMPLE: $29,217.00 divided by 100 = $297.12 X 7.6463 = $2,271.88 (rounded).
