Frequently Asked Questions
What is Unigov and how does it affect Marion County residents?
Unigov is the consolidated city-county government of Indianapolis and Marion County, established by Indiana state legislation effective January 1, 1970. It merged most city and county government functions under a single mayor and City-County Council. For most Marion County residents, this means dealing with one integrated government — Indianapolis city-county — rather than separate city and county offices. Key exceptions are the four "excluded cities" (Beech Grove, Lawrence, Southport, and Speedway), which maintain their own governments.
Why did Indianapolis pass Unigov without a public vote?
The architects of Unigov — Mayor Richard Lugar and the Republican-controlled Indiana legislature — believed a public referendum would fail, as Nashville's and Jacksonville's consolidations had required voter approval. By passing Unigov through the state legislature, they bypassed the referendum process. Critics at the time and since have argued this was undemocratic and that it diluted Black political influence in Indianapolis by absorbing 250,000 largely white suburban residents into the city's political unit overnight.
How do I appeal my Marion County property tax assessment?
File Form 130 with the Marion County Assessor's Office at 200 E. Washington Street, Suite 1360, Indianapolis. For 2025 assessed values, the appeal deadline is June 15, 2026. If the assessor does not resolve the appeal, it goes to the Marion County PTABOA (Property Tax Assessment Board of Appeals). If denied there, you may appeal to the Indiana Board of Tax Review and then to the Indiana Tax Court. Under Indiana Code 6-1.1-15-10, you may pay the prior year's assessed value while your appeal is pending — a significant protection given 2025's large assessment increases.
Does Indiana have a state estate tax or inheritance tax?
No. Indiana repealed its inheritance tax effective January 1, 2013, and has no state estate tax. Only federal estate tax applies, and only for estates above the federal exemption threshold — currently over $13 million per individual. Basic estate planning in Marion County is accessible for most families without complex tax-avoidance structures.
What are the excluded cities in Marion County and how are they different?
The four excluded cities — Beech Grove, Lawrence, Southport, and Speedway — maintained their independent governments when Unigov took effect in 1970. Residents of these communities pay county taxes and receive county services, but they also have their own mayor, city council, and municipal departments for local services like police, parks, and code enforcement. They may vote for the consolidated city mayor and their district City-County Council representative.
Where is the Marion County probate court?
The Probate Division of the Marion Superior Court is located at the City-County Building, 200 E. Washington Street, Indianapolis, IN 46204. Phone: 317-327-4373. Indiana probate is required when a decedent owns real property solely in their name or holds probate assets above the small estate threshold.
