Tax Collection Questions & Answers

  1. What is my parcel identification number (PIN)?

Your PIN number, or parcel identification number, identifies your particular piece of property.  If you need this number, contact the Chief County Assessment Office at (815) 895-7120.  You can give them your name and the property address, and they can provide you with your PIN number.

  1. I haven’t received my tax bill yet. When will I get it?

Tax bills were mailed on April 29, 2022.  If you do not receive your bill by May 15, 2022, or need a duplicate bill, please contact our office at (815) 895-7112 or via email,

  1. What if I do not receive a bill?

If you do not receive a bill, it is your responsibility to contact our office to get a duplicate bill.  If you are a new homeowner and the bill was issued in the previous owner’s name, contact the Treasurer’s Office for a duplicate bill.  Failure to receive a tax bill, or receiving one late for any reason, will not relieve the taxpayer from paying taxes or late penalties.

  1. What if I just purchased the property and didn’t own it last year?

New homeowners should check their real estate closing documents, or with their title company or attorney, to see if they owe taxes due this year.  Depending upon the closing and document recording dates, the tax bill may have been sent to the previous owner.  If you find that you do owe taxes, please contact the Treasurer’s office for a duplicate bill.  By acting quickly, you may avoid delinquent taxes and penalties.

  1. What if I receive a bill that is not my responsibility to pay?

If a mortgage company is to pay your bill, it is your responsibility to call them and ask if you need to send them a copy.  Many mortgage companies now pay electronically and may not require a bill.  If you no longer own the property, it is your responsibility to forward the bill to the new owner.

  1. When is each installment due?

The first installment is due on Thursday, June 2, 2022. The second installment is due on Friday, September 2, 2022.

  1. What do I do if I believe my tax bill is incorrect?

Your tax bill is determined by two factors: the equalized assessed value of your property, and the tax rate.

Questions regarding equalized assessed values or exemptions should be directed to the Chief County Assessments Office at (815) 895-7120.

Tax rates are computed by the County Clerk based on the amount levied by each local governmental taxing body.  Questions regarding tax rates and tax levies should be directed to the County Clerk’s Office at (815) 895-7152.

To protest a tax rate, please contact the DeKalb County Treasurer’s office for detailed instructions for filing an appeal. To effectively appeal a tax rate, you must prove that the rate or a portion of the rate is illegal or excessive. Please contact our office via email at for detailed instructions for filing an appeal of your tax rate.
