The county government is a constitutional body, and is granted specific powers by the Constitution of Indiana, and by the Indiana Code.

County Council: The county council is the fiscal branch of the county government and controls all the spending and revenue collection in the county. Representatives are elected from county districts. The council members serve four year terms. They are responsible for setting salaries, the annual budget, and special spending. The council also has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes, and service taxes.[5][6]

Board of Commissioners: A three-member board of commissioners combines executive and non-fiscal legislative powers. Commissioners are elected county-wide, in staggered four-year terms. One commissioner serves as president. The commissioners also function as the county drainage board, exercising control over the construction and maintenance of legal drains.[5][6]

Courts: DeKalb County has a Circuit Court (75th Judicial Circuit) and two Superior Courts. By local rule, approved by the Indiana Supreme Court,[7] the jurisdiction of the Circuit Court is currently limited to juvenile and domestic cases. Criminal, civil and domestic cases are heard in the two superior courts. Judges of each court are elected for six-year terms on partisan tickets.

County Officials: The county has several other elected offices, including sheriff, coroner, auditor, treasurer, recorder, surveyor, and circuit court clerk. Each of these elected officers serves a term of four years and oversees a different part of county government. Members elected to county government positions are required to declare a party affiliation and to be residents of the county.[6]

DeKalb County is part of Indiana's 3rd congressional district and in 2008 was represented by Mark Souder in the United States Congress.[8] It is also part of Indiana Senate districts 13 and 14,[9] and Indiana House of Representatives districts 51, 52 and 85.[10]
