Search Marshall County Property Records
Marshall County property records are managed by the Supervisor of Assessments in Lacon, the county seat. The office tracks assessed values, ownership details, and exemption filings for every parcel in the county. Township assessors do the field work of setting values on homes, farm ground, and commercial buildings, while the county office reviews those numbers to keep things uniform. Marshall County is a small, mostly rural county in north-central Illinois, and property here is a mix of productive farmland and small town parcels. You can look up records online, call the office, or stop by in person at the courthouse in Lacon.

Marshall County Assessment Office
Patricia Welsh serves as the Supervisor of Assessments for Marshall County. Her office is located at 122 N. Prairie in Lacon (mailing address: PO Box 328, Lacon, IL 61540).

Staff here maintain assessed values for every parcel, process exemption forms, and help guide township assessors who set values on the ground.

If one area looks out of line, the office can step in and adjust things so Marshall County property records remain fair for all owners.
Township assessors in Marshall County handle the on-the-ground work. They check new construction, look over permits, and walk through properties when needed to set values. The assessment date is January 1 each year. All real property in Marshall County gets assessed at 33 1/3 percent of fair market value, the same rate that applies across most of Illinois. After township assessors finish, Patricia Welsh's office reviews the numbers to make sure they are consistent.

Marshall County Property Tax Records
Property taxes in Marshall County are paid in arrears. The bill you pay this year covers the prior year's assessment. Under 35 ILCS 200/, the lien date is January 1. That date sets who owns the parcel and what it is worth for tax purposes. Tax bills split the total owed among each taxing district that covers the parcel. Schools, the county, road districts, and local municipalities all take a share. The rate depends on where the parcel sits within Marshall County.
A home in Lacon may carry a different total tax rate than farmland out in a rural township. That difference comes from the mix of taxing bodies that overlap each area. Understanding how those rates work helps when you read your Marshall County property records. The assessor sets the value. The County Treasurer collects the tax. If you have questions about how much you owe or when a payment is due, the Treasurer handles that side. For anything about the assessed value itself, Patricia Welsh's office at 122 N. Prairie in Lacon is the right place to call.
Marshall County tax bills typically go out in the spring with two installment due dates later in the year. Missing a due date can lead to penalties and interest, so keep those dates marked.
