How Tazewell County Assesses Property

33.33%of market value

Assessed by: Tazewell County Supervisor of Assessments

Assessment cycle: annual

Notices typically mailed: Spring

In Tazewell County, property assessments are based on your home's fair market value multiplied by Illinois's statutory assessment ratio of 33.33%. Assessment notices are typically mailed in the spring each year, providing property owners with both the market value and assessed value. For example, if your home's market value is $164,500 (the county median), at Illinois's 33.33% assessment ratio your assessed value would be $54,833, resulting in approximately $3,481 in annual taxes at the county's effective rate of 2.12%. This equalized assessed value (EAV) is what your tax bill is calculated from, not the full market value.

The Appeal Process

Appeals are heard by the Board of Review. The Board of Review holds formal hearings where you present your evidence to a three-member panel appointed by the County Board. If you submit a detailed package with strong supporting documentation, the county may decide without requiring a formal hearing. The Board deals only with assessed valuations before equalization, not with tax rates or the amount of the tax bill itself.

1

Step 1: Obtain your property record card showing the assessed valuation from the Supervisor of Assessments office at (309) 477-2275 or visit their office at 11 South Fourth Street, McKenzie Building, Suite 410, Pekin, IL 61554.

2

Step 2: Discuss the assessment informally with your township assessor or the Supervisor of Assessments to understand how your assessment was calculated and determine if an informal resolution is possible before filing a formal appeal.

3

Step 3: Gather substantial evidence to support your appeal, including comparable sales data from properties sold in your area within the past 1-3 years, recent professional appraisals, photographs showing property condition or defects, and repair estimates for any needed maintenance.

4

Step 4: File a written complaint using the Non-Farm Property Assessment Appeal form with the Tazewell County Board of Review by June 1, 2026. The Board meets at 11 South Fourth Street, McKenzie Building, Suite 410, Pekin, IL 61554.

5

Step 5: Present your evidence at a hearing before the three-member Board of Review, demonstrating that your property is overvalued compared to similar properties or that errors were made in the assessment.

6

Step 6: If the Board of Review denies your appeal or you disagree with their decision, you may appeal in writing to the Illinois Property Tax Appeal Board (PTAB) within 30 days of receiving the Notice of Findings. Appeal forms are available at www.ptab.illinois.gov/forms.html.

7

Step 7: As a final option, if the PTAB appeal is unsuccessful, you may file a tax objection appeal in Circuit Court within the statutory timeframe to pursue judicial review.

How do I file a property tax appeal with the Tazewell County Board of Review?
To file a property tax appeal in Tazewell County, you must first obtain your property record card from the Supervisor of Assessments office by calling (309) 477-2275. Next, gather evidence including comparable sales from similar properties sold within the past 1-3 years, recent appraisals, photos of property condition issues, and repair estimates. Complete the Non-Farm Property Assessment Appeal form and submit it to the Board of Review at 11 South Fourth Street, McKenzie Building, Suite 410, Pekin, IL 61554-4206 before the June 1, 2026 deadline.

How much is the homestead exemption worth in Tazewell County?
The General Homestead Exemption in Tazewell County reduces your property's equalized assessed value (EAV) by $6,000. At the county's effective tax rate of 2.12%, this exemption saves approximately $127 per year on your property tax bill. Senior citizens age 65 and older qualify for an additional Senior Citizens Homestead Exemption worth $5,000 in EAV reduction (approximately $106 in annual savings), bringing total potential savings to about $233 annually.

The exemptions stack with other programs like the Senior Assessment Freeze for even greater savings if you qualify based on income limits.
What evidence do I need to win my property tax appeal in Tazewell County?
To succeed with your Tazewell County property tax appeal, you need substantial evidence proving your property is overvalued. The most compelling evidence includes comparable sales data from at least three similar properties in your neighborhood that sold within the past 1-3 years for less than your assessed value would suggest. A recent professional appraisal from a certified appraiser carries significant weight. Photographs documenting property defects, needed repairs, or adverse conditions help demonstrate reduced value. Written repair estimates from licensed contractors for major issues like foundation problems, roof damage, or outdated systems strengthen your case. Sales-ratio studies or market analysis showing your assessment is higher than the prevailing 33.33% ratio can also be effective. The key is providing objective, documented evidence rather than subjective complaints about tax rates or neighborhood trends.
Can I appeal to a higher authority if the Tazewell County Board of Review denies my appeal?
Yes, if the Tazewell County Board of Review denies your appeal or you disagree with their decision, you have the right to appeal to the Illinois Property Tax Appeal Board (PTAB) within 30 days of receiving your Notice of Findings from the Board of Review. PTAB is the state-level administrative body that provides an independent review of local assessment decisions. You can download appeal forms at www.ptab.illinois.gov/forms.html. If your PTAB appeal is unsuccessful, you have one final option: filing a tax objection appeal in Circuit Court for judicial review. Each level of appeal requires careful documentation and adherence to strict deadlines, so it's important to act quickly after receiving decisions at each stage.
How does Tazewell County calculate my property's assessed value?
Tazewell County uses Illinois's statutory assessment ratio of 33.33% to calculate your assessed value. First, the township assessor or Supervisor of Assessments determines your property's fair market value based on recent sales of comparable properties, property characteristics, and market conditions. This market value is then multiplied by 33.33% to arrive at your assessed value, also called equalized assessed value (EAV). For example, if your home has a market value of $164,500, your assessed value would be $54,833 ($164,500 × 0.3333). Your tax bill is then calculated by multiplying this assessed value by your local tax rate. Tazewell County assesses properties annually, and the Supervisor of Assessments office applies equalization factors as needed to ensure countywide assessments meet the 33.33% standard.
What happens at a Board of Review hearing in Tazewell County?
At a Tazewell County Board of Review hearing, you'll appear before a three-member panel appointed by the County Board to present your case for why your property assessment should be reduced. The hearing is typically held at the Assessment Office in the McKenzie Building, Suite 410 in Pekin. You'll present your evidence, which may include comparable sales data, appraisals, photographs, and repair estimates, while explaining why your property's assessed value is too high. The township assessor may also present their evidence supporting the current assessment. The Board members may ask questions about your property and evidence. In some cases, if you submit a very strong evidence package in advance, the Board may grant a reduction without requiring you to attend a formal hearing. The Board focuses solely on whether the assessed value accurately reflects your property's market value at the 33.33% ratio, they cannot adjust tax rates or bills.
How much can I save by appealing my property taxes in Tazewell County?
The potential savings from a successful property tax appeal in Tazewell County depends on how much your assessment is reduced. At the county's effective tax rate of 2.12%, every $1,000 reduction in your property's market value saves you approximately $7.07 annually in property taxes (calculated as $1,000 × 33.33% assessment ratio × 2.12% tax rate). If you successfully prove your home's market value should be $150,000 instead of $164,500 (the county median), that $14,500 reduction would save you approximately $102 per year. Many successful appeals result in reductions of 5-10% of assessed value. Statistics show that about 25% of homes nationwide are overassessed by an average of $1,346 annually, and Tazewell County's higher-than-average tax rate means the savings from correcting an overassessment can be even more substantial here. These savings continue year after year until your next reassessment.
