Search a Tazewell County Assessment and Follow the PIN Through the Tax Record
Tazewell County’s property system starts with the township assessor and county Supervisor of Assessments. The county’s DEVNET Property Tax Inquiry then brings assessment, parcel, structure, sale and tax information together in one searchable record.
The important Illinois detail is that assessed value is normally about one-third of fair cash value—not the full market value. From there, equalization and exemptions affect Equalized Assessed Value before local tax rates produce the bill collected by the Treasurer.

Search by PIN, owner, address, sale, legal description or township
Tazewell County’s online system is more detailed than a simple address lookup. Use only the fields you actually know; entering several uncertain criteria can accidentally filter out the correct parcel.
Best when you already have a tax bill or prior county record.
- Enter the parcel number carefully.
- Open the matching record.
- Verify the site address.
- Save the PIN for payment or calls.
Useful when you know the taxpayer but not the PIN.
- Begin with the surname.
- Add the first name only if needed.
- Try trust or company wording separately.
- Check former owners after a recent sale.
The search has separate house-number and street-name criteria.
- Enter the house number.
- Add the main street name.
- Leave uncertain fields blank.
- Compare multiple results when necessary.
The portal can also search broader research criteria.
- Tax codes and districts
- Sale-price range
- Sale-date range
- Legal description
- Property class
- Township / municipality
- Tax-year range
After the parcel opens
Mobile-home records use their own search in the same portal
The DEVNET system separates parcel searches from mobile-home searches. Do not force a mobile-home record into the ordinary real-estate parcel form.

Tazewell County assessments target 33⅓% of fair cash value
Fair cash value → assessed value → EAV
Illinois law generally values property outside Cook County at one-third of fair cash value. Tazewell County describes equalization as a uniform percentage increase or decrease used to bring assessment levels toward the statutory 33.33% level.
A $300,000 market value therefore corresponds to a basic assessed value of about $100,000 before any equalization factor. Applicable homestead exemptions are then deducted from EAV before the tax rate is applied.

Estimate assessed value, EAV and property tax
Tazewell County assessment-to-tax estimator
Enter a market value, equalization factor, total EAV exemptions and the combined tax rate shown for the parcel. The rate field is an example input—not a countywide default.
Approximate formula: market value ÷ 3 = assessed value; assessed value × equalization factor = EAV; EAV − exemptions = taxable EAV; taxable EAV × tax-rate percentage = estimated tax.
Both regular 2026 real-estate tax installments are now past due
Tazewell County is collecting 2025 real-estate taxes payable in 2026. The first installment was due June 1, 2026 and the second installment was due September 1, 2026.
Know the PIN and payment fee before submitting a Tazewell tax payment

Check exemptions before assuming the assessment itself is wrong
Homestead exemptions reduce taxable EAV rather than changing the underlying market value. Tazewell County’s Assessment Office provides forms for senior, disability, veteran, improvement and other exemption programs.
Appeal the assessment, not the amount printed on the tax bill
Tazewell County’s Board of Review hears complaints about property valuation established by the township assessor or Supervisor of Assessments. The Board does not decide whether local school, park, municipality or other taxing-body rates are too high.

Evidence Tazewell County identifies as useful
Use GIS for parcel context and the Recorder for legal documents
The Assessment Office links a dedicated Property GIS Search and the county ArcGIS site. GIS is useful for locating a parcel, understanding surrounding tracts and comparing geography.
The Recorder maintains deeds, mortgages, plats, subdivisions, land surveys, contracts for deed, releases and other documents affecting real estate.

Tazewell County tax assessment search and records FAQs
1. Where can I search Tazewell County, Illinois property assessments?
Use the official Tazewell County Property Tax Inquiry at tazewellil.devnetwedge.com. The portal supports searches by parcel number, owner, street address, taxing district, sales information, legal description, property class, township and tax year.
2. Who assesses property in Tazewell County?
Tazewell County uses a township-assessment system. Township assessors establish property values, and the Tazewell County Supervisor of Assessments coordinates county assessment records and equalization functions.
3. What percentage of market value is used for a Tazewell County assessment?
Most Illinois property outside Cook County is assessed at 33⅓% of fair cash value. A property with a $300,000 fair cash value would therefore have a basic assessed value of about $100,000 before equalization.
4. What is Equalized Assessed Value in Tazewell County?
Equalized Assessed Value, or EAV, is the assessed value after the applicable equalization factor is applied. Qualifying homestead exemptions are then deducted from EAV before the local tax rate is applied.
5. What were Tazewell County’s 2026 real-estate tax due dates?
The county states that 2025 real-estate taxes payable in 2026 were due June 1, 2026 for the first installment and September 1, 2026 for the second installment. Both regular deadlines have now passed.
6. What happens if my 2026 Tazewell County property taxes are late?
Tazewell County states that unpaid installments are assessed interest at 1½% per month. The county’s published 2026 annual tax-sale date is October 19, 2026, so use the live tax record or contact the Treasurer for the current payoff amount.
7. How much does Tazewell County charge to pay property taxes online?
The current county payment page lists a 2.25% convenience fee for credit or debit cards with a $1.95 minimum per transaction. E-checks carry a flat $1.25 provider fee. These fees go to the service provider rather than Tazewell County.
8. How do I appeal a Tazewell County property assessment in 2026?
Start by discussing the record with the township or county assessing official, then use the Tazewell County Board of Review process if the issue is not resolved. The county’s public Board of Review page still shows the 2025 filing deadline, so call 309-477-2277 to verify the current 2026 deadline rather than reusing the old date.
9. What is the current income limit for the Tazewell County Senior Assessment Freeze?
Tazewell County’s Assessment Office states that the income amount has increased to $75,000. Senior Freeze submissions should include the appropriate Form 1040 or other supporting income documentation.
10. Can I use the Tazewell County GIS map as a legal survey or title record?
No. Tazewell County’s GIS information is maintained primarily for property-tax and reference purposes. Use the Recorder for recorded land documents and a licensed surveyor when an exact legal boundary is required.

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties.
