State of Illinois Property Records: Search County Deeds, PINs, Tax Bills, Assessments & GIS Maps

How to Find an Illinois Property Index Number, Parcel Record or Assessment
The Property Index Number is the key that connects Illinois assessment records, tax bills, GIS maps and many recorded-document searches. In many counties, it is also called PIN, parcel number or permanent index number.
Tax bill or assessment notice
IDOR says the PIN is located on the county tax bill or assessment notice.
Ask lender for bill copy
If taxes are paid through a mortgage, IDOR says you can contact the lender for a bill copy.
Ask county assessor
IDOR also says you may get the PIN from your county assessor’s office.
1
Identify the county firstIllinois has 102 counties; records are local.
▾
Use the property address to confirm the county. Do not assume the mailing city equals the taxing county. In suburban areas, the same city name can cross township, school district or county lines.
2
Open the county assessor or county property searchSearch by address first if you do not know the PIN.
▾
Step 1: Search the county assessor, supervisor of assessments, or county property lookup. Step 2: enter address, PIN or map detail. Step 3: confirm township/city and property class. Step 4: save the PIN for deed, tax and GIS searches. State county-contact route: Illinois Property Tax Number County Contact Information.
3
Use address-format tricks when search failsMost county portals are strict about street formats.
▾
Try house number plus street name only. Remove apartment/unit labels, “Street,” “Avenue,” “Road,” punctuation and directional words if the county search suggests it. Cook County’s address search, for example, says not to include street designations like Ave., St. or Pl.
4
Save the PIN and assessment detailsYou will reuse them in tax, GIS and deed research.
▾
Copy the PIN, property address, township, tax code, assessed value, exemptions, owner/mailing details where public, property class, legal description and latest assessment year.
How to Search Illinois Deeds and Land Records
Illinois deed records are recorded at the county level. Depending on the county, the office may be called Recorder of Deeds, Recorder, County Clerk and Recorder, or County Clerk.
Grantor / grantee
Use seller, buyer, trust, LLC, lender and prior-owner names when searching recorded documents.
Document number
If you have a document number, recording date, book/page or instrument number, use it first.
Search forward
After a mortgage or lien appears, search later records for releases, satisfactions or assignments.
1
Find the county recorder or clerk/recorderThe county where the property is located controls the record.
▾
Do not search a statewide deed portal first. Open the county recorder or county clerk/recorder website. Some large counties have separate document-index portals, while smaller counties may use county clerk systems or vendor search tools.
2
Search by party name and document typeUse grantor/grantee and narrow date ranges.
▾
Search buyer and seller names, spouse names, trust names, LLC/corporation names, lender names and document types such as deed, mortgage, release, lien, easement, plat, assignment or satisfaction. Narrow by date range when the county index returns too many results.
3
Use transfer declarations as a sales clueMyDec can help confirm transfer data, but it is not the deed image itself.
▾
Illinois MyDec allows users to search recorded Real Estate Transfer Declarations without logging in. Use transfer declaration information as a clue, then verify the recorded deed in the county recorder’s land-records system. MyDec route: Illinois Property Transfer Tax Declarations and MyDec.

Order certified copies only from the official county officeCertified copies are not the same as screenshots or third-party reports.
▾
If a lender, court, title company, attorney, agency or estate matter asks for a certified deed, order from the county recorder or county clerk/recorder. Verify current copy and certification fees on that county’s official website before ordering.
How to Search Illinois Property Tax Bills and Payment History
Illinois property tax bills are handled by county treasurers or collectors. Due dates, installment rules, interest, penalties, payment methods and refund searches vary by county.
PIN first
The PIN connects assessment, bill and payment records in most counties.
Check lender
If taxes are paid by mortgage escrow, ask the lender for tax-bill proof and compare county posting.
County-specific
Some counties offer refund, duplicate payment or missing exemption searches.
Verify county rules
Late interest, tax sale process and redemption rules are county-administered and time-sensitive.
1
Open the county treasurer or collectorUse the county, not a generic property site.
▾
Search the county treasurer, collector or property tax portal by PIN, address, owner or bill number. Verify tax year, installment, bill type, payment status and whether the amount is current or delinquent.
2
Compare the tax bill to the assessment recordValue and bill are related but not identical.
▾
The assessor sets or maintains assessment information, while the treasurer/collector collects taxes. Tax bills depend on assessment, equalization, exemptions, tax rates, tax codes and local taxing districts.
3
Save payment proof before closing the portalUseful for escrow, refinance, sale and duplicate-payment disputes.
▾
Save PIN, tax year, installment, billed amount, payment date, confirmation number, receipt number, tax code and parcel address. If the mortgage company should have paid, compare the county record with escrow statements.
4
Handle delinquent taxes directly with the countyDo not guess payoff, tax sale or redemption amounts.
▾
If taxes are delinquent or a tax sale is possible, call the county treasurer/collector with the PIN, tax year and property address before paying or buying. Legal deadlines and payoff amounts can change quickly.
How Illinois Real Estate Transfer Declarations Fit Into Property Records
Illinois property transfers often include a Real Estate Transfer Declaration, commonly PTAX-203. This is useful for sales-data research, but it does not replace the recorded deed.
Sales data
IDOR says county offices and IDOR use PTAX-203 information to collect sales data and support assessment ratio studies.
County recorder
PTAX-203 or an exemption notation is filed with the deed or trust document at the county recorder’s office.
MyDec
MyDec lets users search recorded Illinois Real Estate Transfer Declarations without logging in.

Use MyDec for transfer declaration cluesGood for sale research, not the full deed chain.
▾
Open IDOR’s MyDec information page and use the MyDec search route for recorded Real Estate Transfer Declarations, including PTAX-203, PTAX-203-A and PTAX-203-B. Action page: Illinois MyDec and Transfer Declarations.

▾
Use the buyer/seller names, sale date, county and transfer information to locate the recorded deed in the county recorder or clerk/recorder land-records system.
3
Understand when PTAX-203 is requiredMost transfers need a declaration or exemption notation.
▾
IDOR instructions say a filer must file Form PTAX-203 and required documents with the deed or trust document, or include an exemption notation on the original deed or trust document at the county recorder’s office where the property is located.

If Your Illinois Property Records Search Fails
| Problem | Likely Cause | Fix |
|---|---|---|
| No statewide property record found | Illinois property records are county-based. | Identify the county, then search assessor, recorder, treasurer or GIS by record type. |
| No PIN result by address | Street suffix, unit, direction, township or city mismatch. | Search house number + street name only, remove suffixes, and confirm county/township. |
| Owner search not available | Some counties restrict or format owner-name search differently. | Use PIN, property address, map search or tax bill details instead. |
| Tax bill owner name is old | Deed transfer, assessor update and treasurer billing cycles may not align. | Check recorded deed, assessor record and treasurer mailing-name process. |
| Deed search too broad | Common surname, trust, LLC or wide date range. | Narrow by county, document type, recording date, grantor/grantee, book/page or instrument number. |
| Tax payment not posted | Processing delay, wrong PIN, wrong installment or mortgage escrow timing. | Compare county receipt, bank record and escrow statement; call county treasurer with PIN. |
| GIS boundary looks wrong | GIS is informational and may not equal a legal survey. | Use recorded plats, surveys, legal descriptions and professional survey/title review. |
| Need legal title proof | Tax or assessor record is not title insurance. | Search recorder records, releases, liens and judgments; use a title company or attorney. |
