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.

Jurisdiction check: this page covers Tazewell County, Illinois, including Pekin, East Peoria, Washington, Morton, Tremont and surrounding townships. Tazewell County, Virginia uses a completely different Commissioner of the Revenue system.

Separate search tab

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.

Mobile-home number Search the mobile-home number with or without dashes.
Owner name Use the owner name as it appears on the mobile-home tax bill.
Site address Search by house number, street name and city when the mobile-home number is unknown.
Search troubleshooting

If the Tazewell County property search returns nothing useful

Full owner name fails? Remove initials and first-name details. Search the surname or core trust/company name first.
Address gives no result? Enter only the house number and main street name. Avoid filling every search field.
PIN does not match? Recheck every digit. The Treasurer says the payment PIN on the tax bill is a 12-digit number.
Recent sale still shows older information? Search both current and former owner names, then use Recorder records if legal ownership is the issue.
Vacant land has no useful street address? Search the PIN, legal description or county GIS instead.
One owner has many parcels? Filter by township, street, legal description or property class rather than guessing from owner name alone.
Need an older tax year? Use the portal’s “Search All Tax Years” and tax-year range fields.
Still cannot identify the parcel? Call the Assessment Office at 309-477-2275 with the address, owner and any known PIN or legal-description information.

Illinois assessment math

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.

Do not confuse market value, assessed value and EAV
Stage
Meaning
$300,000 example
Fair cash value
Estimated full market value.
$300,000
Assessed value
Generally 33⅓% of fair cash value.
About $100,000
Equalized assessed value

Depends on the factor.
Taxable EAV
EAV after qualifying exemptions.
Depends on exemptions.
Tax
Taxable EAV multiplied by the parcel’s combined tax rate.

Farmland is different. Illinois agricultural land uses productivity-based assessment rules rather than simply applying the normal market-value formula to farmland.
Assessment calculator

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.

Illinois does not have one universal Tazewell County property-tax rate. The actual rate depends on the taxing bodies in the parcel’s tax code.
Assessed value $100,000
EAV $100,000
Taxable EAV $100,000
Tax estimate $8,000

Approximate formula: market value ÷ 3 = assessed value; assessed value × equalization factor = EAV; EAV − exemptions = taxable EAV; taxable EAV × tax-rate percentage = estimated tax.

2026 payment status

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.

June 1, 2026 First installment due date. This deadline has passed.
September 1, 2026 Second installment due date. This deadline has also passed.
1.5% per month County guidance says unpaid installments are assessed interest at 1½% per month.
October 19, 2026 Tazewell County’s published 2026 annual tax-sale date.
If either 2026 installment is unpaid: do not pay the original coupon amount without checking the live tax record. Interest or other collection charges can change the amount required.
Not receiving a bill does not stop penalties. The Treasurer states that failure to receive the real-estate tax bill, or receiving it late, does not remove penalties when payment misses the due date.
Treasurer / Collector

Know the PIN and payment fee before submitting a Tazewell tax payment

Tazewell County Treasurer Hannah Clark also serves as Collector. The Treasurer receives tax information after the County Clerk computes rates and then handles tax billing, collection and distribution.

Assessment relief

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.

Senior Homestead Tazewell County provides Form PTAX-324 through the Assessment Office.
Senior Assessment Freeze The county states that the household-income limit has increased to $75,000.
Disability & veteran forms The Assessment Office provides current disability, disabled-veteran and returning-veteran exemption forms.
Confirm the property is your qualifying principal residence
Check whether an exemption already appears on the record
Use the current county form for the correct tax year
Senior Freeze filers should prepare required income documentation
County recommends initial homestead submissions in person for verification
Keep a copy of the filed form and supporting documents
Senior Freeze document note: the Assessment Office says a Senior Freeze submission should include the appropriate federal Form 1040 or other supporting income documents.
Board of Review

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.

Do not reuse the 2025 deadline for a 2026 appeal. As of this update, Tazewell County’s public Board of Review page still displays September 19, 2025 as the filing deadline and does not publish a replacement 2026 deadline on that page. For a 2026 assessment, verify the current filing date directly with the Board of Review at 309-477-2277.

Use the local review path in this order

Obtain the property record Save the parcel page, assessment, property sketch and structure information relevant to the dispute.
Talk with the township or county assessing official first Illinois recommends raising an apparent error early while the assessing official may still be able to correct the record informally.
Determine the fair cash value you can support A successful complaint needs evidence, not simply a statement that the property tax increased.
Choose the actual basis for complaint Common grounds include excessive market value, incorrect property information, lack of assessment uniformity or a higher assessment than similar properties.
File the appropriate written complaint on time Follow the current Tazewell County Board of Review packet and deadline for residential, commercial or farm property.
Preserve the next appeal option A Board of Review complaint is generally required before a further appeal to the Illinois Property Tax Appeal Board or a tax-objection case in Circuit Court.

Evidence Tazewell County identifies as useful

Subject property’s record card and photographs
Comparable property cards and photographs
PTAX-203 transfer declaration
Deed or purchase contract
Professional appraisal
Recent comparable sales
Evidence of incorrect lot or building measurements
Photos and cost evidence for value-reducing defects
Board of Review deadline script “I’m reviewing parcel [PIN] for the 2026 assessment year. Your webpage still displays the 2025 filing date. Can you confirm the 2026 publication date, final complaint deadline and the correct residential/commercial/farm appeal packet for this parcel?”
GIS & recorded land records

Use GIS for parcel context and the Recorder for legal documents

Tazewell County GIS

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.

County Recorder

The Recorder maintains deeds, mortgages, plats, subdivisions, land surveys, contracts for deed, releases and other documents affecting real estate.

GIS is not a title search or boundary survey. Tazewell County’s GIS disclaimer says parcel/map information is maintained primarily for property-tax purposes and should not be relied on as a substitute for a title search.

10 Tazewell County-specific answers

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. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
