Your Marion County tax bill is full of township names — Center, Lawrence, Pike, Wayne, and the rest of the nine townships that structure Indianapolis property taxes. So it surprises many owners to learn that no township official sets their assessed value. There is no Center Township assessor, no Wayne Township assessor — indy.gov's agency directory lists exactly one assessing office for the entire county. Here's how that happened, and why it changes how you should think about your next appeal.
The 2008 reform, as the statute actually reads
Indiana's 2008 property tax reform (P.L.146-2008, the same act that created the tax caps) restructured assessment administration statewide, and the mechanics are still visible in the Indiana Code today:
- Small townships transferred automatically. Under IC 36-6-5-1(h), after June 30, 2008, the county assessor performs the assessment duties in any township with fewer than 15,000 real property parcels as of January 1, 2008.
- Large townships got a vote. Under IC 36-6-5-1(d), a township assessor could be elected after 2008 only in a township with at least 15,000 parcels and where voters disapproved the transfer in a referendum. The question went on the November 2008 general election ballot in those townships, worded: "Should the assessing duties of the elected township assessor in the township be transferred to the county assessor?"
- The office's assets moved with the job. IC 36-2-15-0.3 transferred township assessors' personnel, property, obligations, and funds to the county assessor.
- The scaffolding was later removed. The referendum machinery added to IC 36-2-15 by P.L.146-2008 had done its work and was repealed by P.L.167-2015 — a sign of how settled the consolidation now is.
In Marion County, the outcome was total: no township assessor's office survives here. Every parcel in all nine townships is assessed by the Marion County Assessor's Office, led since his 2010 election by Joseph P. O'Connor, working from the City-County Building with satellite offices on the north and east sides.
Note
The county assessor's statutory duties under IC 36-2-15-5 include countywide equalization, selection and maintenance of a countywide computer system, certification of gross assessments to the county auditor, and discovery of omitted property — plus the assessment duties in every township without an elected township assessor. In Marion County, that's all of them.
Townships still matter — just not for who assesses you
Consolidation did not make township lines meaningless. Townships survive as government units (indy.gov still lists township trustees, who run fire protection and assistance in some areas), and more importantly they define taxing districts. Marion County's 2026 certified rates run from $2.4269 per $100 of assessed value in Franklin Township outside Indianapolis to $4.2369 in Beech Grove's Center Township district — the Beech Grove, Speedway, Lawrence, and Southport rate spread exists entirely at the district level. Your township determines your rate stack. It just no longer determines who values your house.
Tip
Practical translation: if your assessment looks wrong, don't look for a township office to call. If your rate looks wrong, township and district are exactly where to look — start with where your tax dollars go.
What one assessor means for your appeal
For appeals, consolidation is mostly good news, and it shapes strategy in three ways.
One office, one filing path. Every Marion County appeal is a Form 130 filed with the county assessor, regardless of township. There is no township-level review step; after filing, your case goes to informal review and then the county PTABOA — a county board, notably one on which the county assessor serves as secretary.
Comparables cross township lines more credibly. Before consolidation, nine offices could apply grade, condition, and land tables nine different ways. With a single office applying one methodology, an inconsistency between your card and a similar home in the next township over is harder to wave off — equity arguments built from neighboring record cards carry real weight, and countywide equalization is literally the assessor's first statutory duty.
Volume cuts both ways. One office valuing every parcel in the county leans heavily on mass appraisal models, which is precisely why the 40% success rate for Marion County appeals shouldn't surprise anyone: models miss individual properties, and the appeal process exists to catch what the model missed.
Warning
The 2026 appeal window closed June 15. If you're reading this with a 2026 grievance, the correction-of-error route is still open for objective mistakes, and the 2027 cycle starts when Form 11 notices land next spring. Build the file now.
The bottom line
Marion County's assessment system is one office, nine townships, one appeal path. That's simpler than the pre-2008 world — and it rewards owners who understand the county's single methodology well enough to challenge it.
