State Auditor Tera Klutz, who was appointed to her position in January, is running for a full term.
Klutz formally kicked off her 2018 campaign Wednesday at an event in Fort Wayne.
Gov. Eric Holcomb appointed Klutz to finish the term of Suzanne Crouch, who is now lieutenant governor.
Klutz is from the Fort Wayne area and was elected to two terms as Allen County auditor.
Her campaign says she is the first certified public accountant to serve as state auditor in Indiana history.
She was named the 2016 County Auditor of the Year by the Indiana Auditors' Association.
