How Property Assessment Is Organized in Indiana
Indiana leaves the job of valuing real estate to local assessors, but the rules come from the state. Property tax law sits in Title 6, Article 1.1 of the Indiana Code. The Department of Local Government Finance (DLGF) in Indianapolis supervises how counties apply it. The assessor sets a value. Other offices turn that value into a bill. Knowing which office does what saves you a wasted trip.
Indiana has 92 counties, and each one elects a county assessor. The assessor's office keeps property record cards, measures new construction, tracks sales, and updates values every year. The state uses a market value-in-use standard. In plain terms, that means what a typical buyer would pay for the property as it is currently used. Values are tied to a January 1 assessment date.
Three county offices touch your property tax, and residents often mix them up:
- Assessor: determines the assessed value, maintains the property record card, mails the notice of assessment, and processes sales disclosure forms after a real estate sale.
- Auditor: compiles the tax rolls, applies deductions such as the homestead deduction, and calculates the bill once local tax rates are set.
- Treasurer: collects the money. Bills are generally payable in two installments, due May 10 and November 10.
If your question is about the value on your bill, start with the assessor. If it is about a missing deduction, start with the auditor. If it is about a payment or a penalty, call the treasurer. Many Indiana residents sit in the wrong line because the three offices are often in the same courthouse or government center.
Metro Indianapolis and Rural Indiana: What Changes by County
The statewide rules are the same everywhere, but the experience of dealing with an assessor differs a great deal. The biggest contrast is between the Indianapolis area and the farm counties.
Marion County and the Indianapolis suburbs
Marion County has the most listings in our database, with eight. Indianapolis is a consolidated city-county, and the county is divided into nine townships: Center, Decatur, Franklin, Lawrence, Perry, Pike, Warren, Washington and Wayne. That history explains why you will find a Wayne Township Assessor at 1502 West 16th Street in Indianapolis, reachable at 317-327-7412. Assessment responsibilities have shifted over the years, so confirm which office currently handles your parcel before you go.
North of the capital, Hamilton County has five listings, including the Fall Creek Township Assessor at 12637 Walrond Road in Fishers. Fishers sits in Fall Creek Township. Fast-growing suburbs like this one see constant new construction, so assessors there spend much of the year adding new homes and additions to the rolls. If you recently finished a basement or built a deck, expect that to show up on your next notice.
In the northwest, Lake County and Porter County sit in the Chicago orbit. The Hanover Township Assessor in Cedar Lake serves part of Lake County. In Porter County, our listings include the Center Township Assessor at 155 Indiana Avenue in Valparaiso and the Pine Township Assessor at 12 West Dunes Highway in Chesterton.
Smaller counties and county seats
In most of Indiana, the office you want is the county assessor's office, usually in the county seat. In DeKalb County, that means the office at 100 Main Street in Auburn, phone 260-925-1824. Noble County's office is at 101 North Orange Street in Albion, phone 260-636-2297. In Steuben County, it is at 317 South Wayne Street in Angola. These offices are small. A single call often gets you the deputy who knows your parcel.
In St. Joseph County, the Assessor's Office is at 227 West Jefferson Boulevard in South Bend, phone 574-235-9557. South Bend has three listings, more than any Indiana city except Indianapolis. Its county office handles a mix of urban lots, suburban subdivisions and farmland, so bring the parcel number to speed things up.
One practical detail trips up callers. Most of Indiana observes Eastern time, but twelve counties in the northwest and southwest corners run on Central time. Lake, Porter, Warrick and Perry are among them. If you are calling a Central-time office from an Eastern-time city, check the hours first.
Visiting an Indiana Assessor's Office: What to Bring and When to Go
Property records are public in Indiana, and you do not need to be the owner to look up a value. Most visits are quick when you arrive prepared. Offices typically keep weekday business hours, but hours vary, so call ahead. Avoid the weeks just after assessment notices go out, when phone lines and counters are busiest.
Bring the following to your visit:
- The parcel number, which appears on your tax bill and notice of assessment.
- The property address and the name on the deed.
- Your most recent assessment notice, if you are questioning a value.
- Evidence for a dispute, such as a recent appraisal, a closing statement, repair estimates or dated photographs.
- Building permits or plans if you added or removed a structure.
Good evidence is specific. A photograph of a crumbling foundation does more than a general complaint that values are too high. Comparable sales from your own neighborhood, near the January 1 valuation date, carry the most weight.
After you buy or sell property, a sales disclosure form is filed through the county. The assessor uses that data to keep values in line with the market. If your price looks unusual, such as a sale between relatives, explain that on the form. It helps the office decide whether the sale reflects true market value.
Challenging an Assessment in Indiana: The Appeal Path
Each year, owners receive a notice of assessment from the county. It is not a tax bill. It shows the value the assessor assigned to your land and improvements. If the value looks wrong, you have a clear process, and it starts locally.
First, call the assessor's office. Many errors are simple. The record might list a finished basement you do not have, a wrong square footage, or an extra bathroom. A deputy can often fix these on the spot without a formal appeal.
If that fails, file a Form 130 petition with the county assessor. The deadline is tied to the date on your notice, and it is commonly 45 days, so read your notice carefully. The assessor may offer a preliminary conference to try to settle the matter. If you do not settle, the county Property Tax Assessment Board of Appeals (PTABOA) holds a hearing and issues a decision.
If you still disagree, you can appeal to the Indiana Board of Tax Review, which is a state-level body. The next and final step is the Indiana Tax Court. Most homeowners resolve their issue at the first or second step.
One caution is worth remembering. An appeal challenges the assessed value, not the tax rate. Rates are set by local taxing units such as schools, townships and cities. Indiana also caps the property tax bill as a share of assessed value, at 1 percent for homesteads, 2 percent for other residential property and farmland, and 3 percent for other property. Those caps shape what you finally pay, whatever the assessor decides.
Property assessor offices in Indiana operate under state property tax statutes that specify how properties must be valued, how often reappraisals occur, and what exemptions are available to qualifying homeowners. The state department of revenue or taxation typically provides oversight and technical guidance to county assessors to ensure consistent valuation practices statewide.
Assessor locations are available in 114 cities across Indiana. They are spread across 92 counties.
Cities with the highest concentration include Indianapolis, South Bend, Madison, where high real estate activity and complex commercial properties create greater demand for assessor services and property valuation resources.
Property owners in Indiana should verify that their primary residence homestead exemption is active and confirm the annual appeal deadline with their local assessor office, as missing the deadline means waiting until the following tax year to contest a valuation.
Assessor by Counties
Many county assessor offices in Indiana now offer online property search tools where homeowners can view their assessed value, recent sales history, and exemption status without visiting the office. If you have questions about a recent reassessment notice, calling or emailing the assessor's office is often the fastest way to get a response before filing a formal appeal.

Reading Indiana's Assessor Listings Without Getting Lost
Our Indiana directory mixes county offices and township offices, and that can be confusing. Names such as Connersville Township Assessor in Fayette County, Marion Township Assessor in Danville, Madison Township Assessor in Madison, and Troy Township Assessor in Cannelton, Perry County, appear alongside county offices like Lawrence County in Bedford, Monroe County in Bloomington and Bartholomew County in Columbus. The township entries reflect how Indiana once split assessing duties across more than a thousand local assessors. Responsibility has since moved heavily toward the county level, so the county assessor is the safest first call in most places.
Here is a simple way to use the listings. Find the county seat for your property. Look for the county assessor's office there. If your parcel is in a township listed in our data, call that office and ask whether it still handles your parcel or whether the county does. The question takes thirty seconds and can save you a drive.
Geography matters too. Porter County has four listings, which means you may need to match a township to your address. In Perry County, along the Ohio River, offices are few and calls are often answered by someone who knows the property personally. Phone numbers and addresses change, so treat our listings as a starting point and confirm hours before you travel.
