ENROLL TODAY In the Property Tax Protection Program™

Your property taxes will be aggressively protested every year by the #1 property tax firm in the country. If your taxes are not reduced you PAY NOTHING, and a portion of the tax savings is the only fee you pay when your taxes are reduced! Many FREE benefits come with enrollment.

Our Coordinated Approach Gives You the Advantage

When O’Connor’s team represents your property for appeal, we handle all the details. Our licensed tax agents work hand-in-hand with attorneys, appraisers, and our research team has access to our proprietary data base to get the best evidence including sales and unequal appraisal data to defend a value reduction for you. We pursue each step in the system to lower your taxes:

  • Negotiations with the Grundy County Assessor
  • Grundy County Board of Review
  • The Illinois Property Tax Appeal Board (PTAB)

How to Protest your Property Taxes with O’Connor

1. Review your property tax assessment

  • Does it look right? Do you feel it should be lower?
  • Are these mistakes?
  • Is the assessor’s market value higher than actual market value?

2. Enroll online with O’Connor

  • We analyze existing documents
  • Our agents research, prepare evidence and present appeals on your behalf
  • Your assigned team coordinates a mutually agreed lawsuit when appropriate

Property Tax Protection Program Benefits
  • No flat fees or upfront costs. No cost ever unless your property taxes are reduced.
  • All practical efforts are made every year to reduce your property taxes.
  • Never miss another appeal deadline.
  • Property taxes protested for you annually.
  • You do not have to accept the appraisal district's initial guesstimate of value.
  • We coordinate with you regarding building size / condition to avoid excess taxes.
  • Free support regarding homestead exemptions.
  • Some years are good - typically 6 to 7 out of 10 will result in tax reduction for you.
  • The other 3 to 4 years out of 10 we strike out. Most often due to people issues in the hearing process. Some years we get an easy appraiser at the informal; some years someone who is impossible to settle with.
