Illinois Township Government: Roles, Services, and Road Districts

Township government in Illinois operates as a distinct layer of local authority beneath county government, delivering property assessment, general assistance, and road maintenance services to residents across the state's rural and suburban areas. Illinois contains 1,432 townships, making it one of the states with the highest township counts in the nation (Illinois Township Officials of Illinois). This page covers how township government is legally structured under Illinois statute, what services townships are authorized to provide, how road districts function within the township framework, and where township authority ends and other units of local government begin.

Definition and Scope

Township government in Illinois is authorized under the Township Code (60 ILCS 1), which establishes the legal powers, officer structures, and fiscal authorities of all general-purpose townships in the state. Each township is a unit of government with its own elected officials, taxing authority, and defined geographic boundary — typically a six-mile-square survey unit, though historical subdivisions and annexations have created irregular boundaries in some counties.

Illinois townships are distinct from municipalities. A township may overlap with multiple municipalities, and a municipality may span more than one township. Residents within an incorporated municipality generally continue to reside within a township jurisdiction simultaneously; the two governments operate in parallel, not in sequence. For comparison with the municipal layer of Illinois government, see Illinois Municipal Government.

Scope and Coverage Limitations

This page addresses general-purpose township government as defined under the Township Code (60 ILCS 1) and road district authority under the Illinois Highway Code (605 ILCS 5). It does not cover:

Township government does not exist uniformly across all Illinois counties. 17 Illinois counties operate under a commission form of county government and have no township layer at all; residents in those counties receive equivalent services directly from county agencies.

How It Works

Each township is governed by a four-member elected board: a supervisor, clerk, assessor, and three trustees. The supervisor serves as the chief executive and fiscal officer, chairs the board of trustees, and administers the General Assistance program. The assessor is responsible for valuing real property within the township for ad valorem tax purposes, operating under the oversight of the county supervisor of assessments.

Township officials are elected to four-year terms at consolidated elections held in April of odd-numbered years under the Illinois Election Code (10 ILCS 5).

Township finances operate through a levy-and-appropriation cycle governed by the Property Tax Code (35 ILCS 200). The township board sets a tax levy by the last Tuesday in December each year, which the county clerk extends against the equalized assessed value of property within the township's boundaries. Illinois townships may levy taxes for:

  1. General corporate purposes (township operations)
  2. General Assistance (welfare relief administered directly by the township)
  3. Road and bridge purposes (if road district authority is vested in the township)
  4. Cemetery maintenance
  5. Mental health services (in some jurisdictions, via separate levy authority)

Common Scenarios

General Assistance Administration

Townships administer General Assistance (GA) under the Illinois Public Aid Code (305 ILCS 5/Art. XII). GA provides emergency financial relief — cash, food, and utility assistance — to residents who do not qualify for state or federal programs. The township supervisor determines eligibility based on income and residency standards set by statute. Each township establishes its own GA schedule, within parameters set by the Illinois Department of Human Services (IDHS).

Property Assessment

The township assessor values all real property within the township at 33⅓ percent of its fair market value as required by the Illinois Property Tax Code (35 ILCS 200/9-145). Residents who dispute their assessments appeal first to the township assessor, then to the county board of review, and ultimately to the Illinois Property Tax Appeal Board or the circuit court.

Road District Operations

Road districts are the township's infrastructure arm. Illinois road districts collectively maintain approximately 60,000 miles of rural local roads — the largest rural road network maintained by a sub-county governmental unit in the United States (Township Officials of Illinois). Each road district is headed by an elected highway commissioner serving a four-year term. The commissioner oversees road construction, maintenance, snow removal, and drainage on roads within the district's jurisdiction.

Road districts operate under the Illinois Highway Code (605 ILCS 5) and receive Motor Fuel Tax distributions from the state through the Illinois Department of Transportation. In townships where road district authority has been consolidated, the township supervisor may serve as ex officio highway commissioner.

Decision Boundaries

Township authority has defined limits that distinguish it from county and municipal power. Key boundary conditions include:

Township vs. Municipality for Road Jurisdiction
Township road districts maintain unincorporated rural roads. Once a road segment is annexed into a municipality, jurisdiction transfers to the municipal government; the road district loses maintenance authority over that segment.

Township vs. County for Assessment
In counties with a population exceeding 3,000,000 — Cook County specifically — the county assessor, not a township assessor, performs all assessment functions. Cook County townships have no assessor offices; the Cook County Assessor (cookcountyassessor.com) holds that authority exclusively.

Township Dissolution
Under 60 ILCS 1/Art. 30, township electors may vote to dissolve a township and transfer its functions to the county. Since 2011, the Illinois General Assembly has expanded dissolution procedures, and several townships in downstate counties have undergone consolidation referenda.

Home Rule Preemption
Home rule municipalities may preempt township authority within their boundaries on specific service matters under Article VII, Section 6 of the Illinois Constitution.
