A licensed appraisal is the most effective instrument a Champaign County homeowner can submit to the Board of Review to reduce an incorrect property tax assessment.
Illinois law gives every property owner the right to challenge the assessed value under 35 ILCS 200/16-55, and a USPAP-compliant appraisal is the primary evidence used to secure a reduction.
Assessment complaints in Champaign County have a hard filing deadline. Whitsitt & Associates produces USPAP-compliant appraisals for Champaign County homeowners who need documented evidence of market value before that window closes.
Yes. Illinois law gives property owners the right to challenge their assessment, and a USPAP-compliant appraisal is the strongest evidentiary instrument available for doing so.
Under 35 ILCS 200/16-55, any property owner who believes their assessed value does not reflect fair cash value may file a complaint with the county Board of Review and submit supporting evidence — a certified appraisal is the most compelling form that evidence can take.
The assessor’s office uses mass appraisal techniques that estimate value across thousands of parcels simultaneously.
A licensed appraiser analyzes your specific property, selects manually adjusted comparable sales, conducts a current interior and exterior inspection, and produces a reconciled value conclusion with documented reasoning.
When those two figures differ, the appraisal gives the Board of Review a documented basis for granting a reduction.
The Champaign County Board of Review is the county-level administrative body that hears property assessment complaints under 35 ILCS 200/16-130. The complaint window opens when the Champaign County Chief County Assessment Officer publishes the annual assessment roll, typically in the summer. Property owners have 30 days from that publication date to file.
| Stage | What Happens | Who Acts |
| Assessment roll published | County publishes assessed values for the tax year | Chief County Assessment Officer |
| Complaint filed | Property owner submits Board of Review complaint form with evidence | Property owner |
| Evidence reviewed | Board reviews submitted appraisal and comparable sales | Board of Review |
| Decision issued | Board issues written decision — reduction granted or denied | Board of Review |
| Further appeal | Owner may appeal to PTAB under 35 ILCS 200/16-160 if relief is insufficient | Property owner |
Filing a complaint requires the official Champaign County Board of Review complaint form, available through the Champaign County Assessment Office.
The form requires the property index number, the owner’s opinion of fair cash value, and supporting documentation. An appraisal submitted without the official complaint form is not processed.
Not every appraisal automatically qualifies as Board of Review evidence. The Champaign County Board of Review requires that submitted appraisals meet specific standards before the document is accepted for review.
The appraisal must reflect market value as of January 1 of the tax year under appeal, not the date the homeowner orders the appraisal. Under USPAP Standard 1, an appraiser may complete a retrospective appraisal — an analysis with an effective date in the past — using sales and market data available as of that date.
The retrospective appraisal process uses the same USPAP standards applied to current-date assignments.
The appraiser must hold an active Illinois license under 225 ILCS 458 and must complete the assignment in conformance with the Uniform Standards of Professional Appraisal Practice (USPAP). Appraisals completed by unlicensed parties or without USPAP compliance are rejected.
The Champaign County Board of Review accepts appraisal reports in the Uniform Residential Appraisal Report (URAR) format for single-family residential properties.
The URAR appraisal report format is the standard instrument used by Whitsitt & Associates for residential tax appeal assignments.
| Requirement | Standard | What Fails |
| Effective date | January 1 of the appeal tax year | Current-date appraisal without retroactive effective date |
| Appraiser licensure | Active Illinois license under 225 ILCS 458 | Unlicensed preparer or out-of-state license |
| USPAP compliance | Uniform Standards of Professional Appraisal Practice | Desktop or automated valuation model (AVM) |
| Report format | URAR for single-family residential | Letter of opinion or broker price opinion (BPO) |
The strength of an appraisal submitted for a tax appeal depends almost entirely on the selection of comparable sales. The Board of Review evaluates whether the appraiser used sales genuinely comparable to the subject property — similar size, condition, location, and age — and whether the adjustments applied are documented and defensible.
Comparable sales should come from within the subject property’s neighborhood or a demonstrably similar market area.
Sales used in a January 1 effective-date appraisal should bracket the effective date—typically within 6 to 12 months before and after —with the most weight given to sales closest to January 1.
The appraiser must bracket the subject’s condition — selecting at least one comparable in better condition and one in worse condition, then adjusting toward the subject. A comparable grid that uses only superior properties without downward adjustments is vulnerable to challenge by the assessor’s representative.
Every dollar adjustment applied in the comparable sales grid must be supported by paired-sales analysis or market-extracted data — not by appraiser opinion alone. The Board of Review has discretion to disregard adjustments that appear arbitrary.
Whitsitt & Associates applies market-extracted adjustment methodology on every tax appeal assignment across Champaign, Piatt, and Douglas counties.
Monitor the Champaign County Assessment Office for the publication date of the 2026 assessment roll. The 30-day complaint window under 35 ILCS 200/16-55 begins on that publication date. Missing the deadline forfeits your right to appeal for that tax year.
Contact Whitsitt & Associates to commission a USPAP-compliant appraisal with an effective date of January 1 of the tax year under appeal. Appraisal turnaround for standard residential properties in Champaign County is typically five to ten business days from the inspection date. Build the appraisal order into your timeline before the filing window opens — not after.
Download the Board of Review complaint form from the Champaign County Assessment Office. Enter your property index number, your opinion of fair cash value supported by the appraisal conclusion, and attach the completed appraisal report as an exhibit.
File the completed complaint form and appraisal with the Champaign County Board of Review by the published deadline. Submissions received after the deadline are not accepted regardless of circumstances. Retain a time-stamped copy of everything submitted.
The Board of Review may schedule a hearing or may rule on the written submission alone. If a hearing is scheduled, Whitsitt & Associates can provide the appraiser’s testimony to support the submitted report. Board of Review decisions are typically issued within 60 to 90 days of the filing deadline.

The Board of Review issues a written decision for every complaint filed. Three outcomes are possible: the assessed value is reduced to the amount supported by the appraisal, the assessed value is partially reduced, or the complaint is denied.
A successful reduction lowers your EAV for the levy year under appeal. The Champaign County Clerk applies the corrected EAV to your tax bill, and a tax credit or refund is issued for any overpayment already collected. The corrected EAV also serves as the starting baseline for the following year’s assessment.
A property owner who receives inadequate relief from the Board of Review may file a further appeal with the Illinois Property Tax Appeal Board (PTAB) under 35 ILCS 200/16-160. PTAB is the state-level administrative tribunal that hears appeals from county Board of Review decisions.
The PTAB process requires a new filing, the original Board of Review decision as an exhibit, and typically takes 18 to 36 months to resolve. The appraisal submitted to the Board of Review can also be filed with the PTAB, provided it remains current or is updated to reflect any changes in the evidence record.
Your appraisal evidence does not expire when the Board of Review rules. Whitsitt & Associates can advise on whether the original report requires an updated assignment before PTAB submission.
Can I use an appraisal to lower my property taxes in Illinois?
Yes. A USPAP-compliant appraisal completed by a licensed Illinois appraiser is the primary evidence Champaign County homeowners submit to the Board of Review under 35 ILCS 200/16-55 to demonstrate that assessed value exceeds fair cash value and obtain a reduction.
What is the deadline to appeal a property tax assessment in Champaign County?
The complaint window opens when the Champaign County Chief County Assessment Officer publishes the annual assessment roll, typically in the summer. Property owners have 30 days from that publication date to file a completed complaint form with the Board of Review.
Does the appraisal have to be completed before I file my complaint?
Yes. The Board of Review complaint form requires the owner’s opinion of fair cash value supported by documentation. Filing without an appraisal leaves the complaint unsupported and significantly reduces the likelihood that a reduction will be granted.
What effective date must the appraisal use for a tax appeal in Illinois?
The appraisal must use an effective date of January 1 of the tax year being appealed. A licensed appraiser completes this as a retrospective appraisal, analyzing market conditions and comparable sales as of that specific date in accordance with USPAP Standard 1.
What if the Board of Review denies my complaint?
A denied complaint can be appealed to the Illinois Property Tax Appeal Board (PTAB) under 35 ILCS 200/16-160. The PTAB process typically takes 18 to 36 months. The appraisal submitted to the Board of Review also serves as the primary evidence exhibit in the PTAB filing.
How much does a tax appeal appraisal cost compared to potential savings?
Appraisal fees for a standard residential assignment in Champaign County vary based on property complexity and the scope of work. A homeowner paying taxes on $30,000 of over-assessed value at a 7% composite rate overpays $2,100 per year. The appraisal fee is typically recovered within the first corrected tax bill.
Can the assessor dispute my appraisal at the hearing?
Yes. The assessor’s representative may present counter-evidence, including a competing appraisal or comparable sales analysis. A USPAP-compliant appraisal with documented, market-extracted adjustments and properly bracketed comparables is the most defensible position a property owner can hold at a Board of Review hearing.
Is a broker price opinion acceptable in place of an appraisal?
No. The Champaign County Board of Review does not accept broker price opinions, automated valuation models (AVMs), or Zillow estimates as evidence of fair cash value. Only a USPAP-compliant appraisal completed by a licensed Illinois appraiser satisfies the evidentiary standard.
What is the difference between the Board of Review and PTAB for Illinois tax appeals?
The Board of Review is the county-level administrative body that hears initial assessment complaints. PTAB — the Illinois Property Tax Appeal Board — is the state-level tribunal that hears further appeals when Board of Review relief is insufficient under 35 ILCS 200/16-160.
Can Whitsitt & Associates provide the appraisal and represent me at the hearing?
Whitsitt & Associates provides the USPAP-compliant appraisal and, when a hearing is scheduled, can provide appraiser testimony in support of the submitted report. The firm does not provide legal representation; property owners requiring an attorney for PTAB proceedings should engage Illinois-licensed legal counsel separately.
A hard deadline closes your appeal window every year. Whitsitt & Associates provides the USPAP-compliant appraisal Champaign County homeowners need to file a supported Board of Review complaint and recover overpaid property taxes before the filing deadline passes.
