Search and Pay Sangamon County Property Taxes

This page helps with Property Tax tasks in Sangamon County, Illinois, including finding a parcel, checking tax information, reviewing payment choices, and knowing when to contact the Sangamon County Treasurer.

Start with the county’s Search for Parcels tool when you need tax or assessment details tied to a parcel number, owner name, or property address.

Search for Parcels

The county parcel search is the main public tool for Sangamon County Property Tax lookup tasks. Most tax website functions, including paying current taxes and filing an assessment complaint, begin by finding the parcel first.

• Parcel number
• Owner name
• House number, direction, street name, or city

Use the strongest information you have. A complete parcel number or owner name can be enough by itself. If you do not have either, use at least 5 digits of the parcel number, a house number, or a street name.

• Go to the Sangamon County Search for Parcels tool.
• Enter the parcel number, owner name, or property address details.
• Select the parcel you want from the results.
• Use the Action field on the results screen to continue with available tax or assessment options.

Search tip: Parcel numbers are usually 11 digits, and the fifth digit is often zero. Spaces and dashes are not required.

Parcel search limits and common issues

If a search returns more than 300 results, the system asks you to narrow your search. Add more specific address details, more parcel digits, or a clearer owner-name entry.

For single-digit numbered streets, the search instructions note that users may need to place a zero before the street number. Owner searches should use last name first, then first name, or the first few letters of the last name.

Current year property tax dates

Sangamon County lists these dates for 2025 taxes payable in 2026.

Payments are assessed a late penalty after the due dates.

Property tax payment options

Sangamon County offers several ways to pay real estate taxes. E-check payments are listed as having no fee. Credit and debit card payments include a convenience fee charged by the card companies.

Last-day rule: Payments on the final in-office payment day are cash or check only.

Estimate Sangamon County property taxes

The Treasurer explains property tax calculation using fair market value, assessed value, equalization factor, exemptions, taxable assessed value, and the tax rate.

For most parcels, fair market value is divided by three to estimate assessed value. The assessed value is multiplied by the equalization factor, exemptions are subtracted, and the result is multiplied by the tax rate per $100 of value.

The county’s example uses a $100,000 fair market value, a $6,000 homestead exemption, a 1.01 equalization factor, and a 7.5 tax rate per $100 of assessed value, resulting in a property tax of $2,074.97.

Pre-payment of property taxes

The Treasurer’s office accepts prepayments for the next year’s property taxes beginning in late November. Prepayments have limits.

• You may pay up to 105% of the prior year’s tax amount unless the prior bill was a partial-year bill.
• The minimum prepayment is at least 25% of last year’s bill.
• Refunds are not issued until bills have been charged against the prepayment in late April.
