Look Up and Pay Peoria County Property Taxes

This page helps users handle a property tax task in Peoria County, Illinois, including tax lookup, payment options, due dates, exemptions, and office contacts.

The main online resource is the Peoria County Property Tax Inquiry. Payment and collection questions generally route through the Peoria County Treasurer, while sold tax redemptions and tax rates involve the County Clerk.

Peoria County Property Tax Inquiry

Use the Peoria County Property Tax Inquiry to search real estate and mobile home tax records. The search page supports parcel searches, advanced parcel searches, and mobile home searches.

• Parcel number, with or without dashes
• Owner last name as shown on the tax bill
• House number and street name, without a direction or street suffix

For best results, start with less information. Too many exact terms can return no records.

• Select the appropriate search type.
• Enter at least one supported search field.
• Review matching parcels and tax information.
• Use the payment option only for the correct parcel and tax year.

Address check: Make sure the Supervisor of Assessments has the current mailing address on file, because not receiving a tax bill does not remove penalties.

Peoria County lists the following dates for 2025 property taxes payable in 2026.

Real estate tax payment options

The Peoria County real estate tax payment options page explains how to pay current real estate and mobile home taxes. Online payments are available after May 1, 2026, and phone payments use 855-394-0671.

Accepted in-person or mail payment methods include cash in office, personal checks, cashier’s checks, certified checks, and money orders. Do not mail cash. Checks should be payable to Peoria County Collector.

Electronic and phone payments require the parcel number, the correct full installment amount, any applicable penalty, and an email address for online payments.

Phone payment note: Phone payments add a $0.95 per parcel service charge in addition to the convenience fee.

Mail, in-person, bank, and township payments

Mailed tax payments must have a U.S. Postal Service postmark on or before the due date. A postage meter imprint is not accepted as proof of timely payment.

In-person payments are accepted at the Peoria County Treasurer’s Office in the Peoria County Courthouse. The office hours for in-person tax payments are 8:30 a.m. to 5:00 p.m.

Some county banks and township collectors may accept payments during the collection period. A tax bill payment stub is required for bank payments, and banks do not accept partial payments.

Understanding your tax bill

The Peoria County tax bill guide explains the main sections of a property tax bill, including parcel number, township, legal description, site address, installment amounts, due dates, mailing address, exemptions, taxing bodies, and penalty information.

For most property types, assessed value is one-third of fair market value. The State of Illinois applies an equalization factor, then exemptions and tax increment finance values are deducted to determine taxable assessed value.

If a payment is made or postmarked after the due date, Peoria County adds a 1.5% monthly penalty, including any part of a month.

Exemptions and tax relief

Peoria County lists several property tax exemptions and relief programs on its tax relief and exemptions page. Some exemptions are automatic after the first filing or are initiated by the Township Assessor, while others require an annual application.

• Owner-occupied exemption lowers equalized assessed value by $6,000.
• Senior Homestead Exemption lowers equalized assessed value by $5,000.
• Senior Assessment Freeze requires annual filing and freezes taxable assessment, not the tax rate.
• Disabled Persons’ Homestead Exemption provides a $2,000 EAV reduction and requires annual application.
• Disabled Veterans’ Standard Homestead Exemption provides reductions based on qualifying disability percentage.

Questions about exemptions should go to the Supervisor of Assessments.

Delinquent taxes and tax sale

For delinquent property taxes, Peoria County directs users to the Treasurer for the annual tax sale process and to the County Clerk for payment options on taxes that have been sold.

The delinquent tax information page explains tax buyer registration, the Annual Tax Sale, penalties, redemption periods, and surplus property auctions. Purchasing taxes at the tax sale does not automatically give the buyer legal rights to the property.

For 2026, tax buyer registrations are accepted through 5:00 p.m. on October 26, 2026. The Annual Tax Sale is scheduled for November 9, 2026, at the Peoria County Courthouse.
