Marion County Industrial Tax Abatements: 2026 Phase-Outs and AV Implications

Marion County has used industrial tax abatements aggressively for two decades. The mechanics: a city or county economic development authority grants a phased deduction on the assessed value of a new industrial investment — usually 10 years, often 100% in year 1 stepping down to 0% by year 10. The abatement is approved by the City-County Council on a project-by-project basis; the County Assessor administers it.

In 2026, several large Marion County industrial abatements either reach their final phase-down year or step down meaningfully — releasing previously-deducted AV back to the tax rolls. The released AV is meaningful in aggregate and worth understanding for any owner, investor, or fiscal stakeholder in Marion County.

How a Marion industrial abatement works

The mechanics under IC 6-1.1-12.1:

City-County Council designates the parcel as part of an Economic Revitalization Area (ERA).
Company applies with details of the planned investment — new building, new equipment, expansion of existing operations.
Council grants the abatement for a term (typically 5 or 10 years) on a phasing schedule.
Assessor calculates the regular AV and then applies the abatement-year deduction to determine taxable AV.
Company files an annual CF-1 statement confirming continued compliance (job creation, investment retention) — failure to file or failure to meet commitments can revoke the abatement.

The standard 10-year industrial phase-down schedule in Indianapolis:

Year	Abatement %	Taxable %
1	100%	0%
2	95%	5%
3	80%	20%
4	65%	35%
5	50%	50%
6	40%	60%
7	30%	70%
8	20%	80%
9	10%	90%
10	5%	95%
11+	0%	100% (fully on rolls)

A 2016-approved abatement is now in year 10 — the final phase-down year — meaning 95% of the AV is on the rolls in 2026, and 100% in 2027. A 2020-approved abatement is in year 6 — half on the rolls.

What's rolling off in 2026

Several categories of Marion industrial abatement are stepping down in 2026:

Final phase-out (years 9–11 of pre-2018 abatements)

Major industrial expansions approved in the 2015–2018 wave are reaching their final years:

Westside logistics and distribution facilities — several 2015–2017 abatements on near-airport and southwest corridor industrial parks
East-side automotive and manufacturing supplier facilities
South-side food processing and beverage facilities

These represent meaningful AV — collectively several hundred million dollars statewide-equivalent assessed value — moving from largely deducted to nearly-fully-taxable.

Mid-phase step-downs

A larger group of 2019–2021 abatements step down from one phase to the next in 2026 (e.g., year 5 to year 6, or year 6 to year 7), each step releasing 10–15 percentage points of AV to the rolls.

Revocations

A small number of Marion abatements have been revoked in 2025–2026 for non-compliance — typically when a facility was closed or downsized below the job-creation commitment. Revocation accelerates the full AV onto the rolls.

Warning

Abatement compliance is taken seriously. Companies that received abatements but then closed Marion County operations or fell below committed jobs/investment thresholds have seen the City-County Council revoke abatements and bill for the deducted years. The Department of Metropolitan Development conducts periodic audits.

AV implications for the broader tax base

When abatements roll off, the deducted AV converts to taxable AV. With the SB 1 levy freeze in place, the rolloff has a specific dynamic:

Levy is frozen, so taxing units can't collect more dollars regardless of base growth.
AV denominator grows as abatement AV converts.
Rate drops to spread the same levy across the larger base.

The benefit flows to all property owners in the affected taxing district — including the industrial parcel itself once its abatement fully expires. Effectively, when a major manufacturer comes off abatement, the rate for everyone in that taxing district drops modestly.

For Marion County's largest taxing district (Center / IPS), even meaningful industrial AV rolling on doesn't change the rate dramatically because the district is so large. For smaller districts (Decatur or Franklin Townships with a single major industrial facility), an abatement rolloff can produce a measurable rate effect.

What it means for specific stakeholders

IPS and other school districts

Cap-bound districts like IPS see modest rate-effect benefit from abatement rolloffs (most homestead parcels are cap-bound anyway, so rate doesn't matter on those parcels). The benefit accrues more on non-homestead parcels in their service area.

The City of Indianapolis

Marginal rate relief; politically, abatement rolloffs are seen as a positive signal of investment maturing.

The industrial company

The taxpayer experience is a step function. A facility that paid 5% of "true" tax in year 1, 20% in year 3, 50% in year 5, etc., experiences taxes climbing on schedule. Companies model this in advance; rolloffs are not surprises.

Surrounding non-abated industrial

Owners of similar industrial parcels that didn't have abatements see modest rate decline as nearby abatements roll off. For a non-abated $5M industrial parcel in the same taxing district, even a 2-cent per-$100 rate decline equals $1,000 in annual tax relief.

The "abatement gap" effect

An important sub-dynamic: while an abatement is active, the abated facility pays less tax than an identical non-abated facility nearby. This creates an abatement gap — older industrial facilities (no abatement) effectively subsidize newer industrial facilities (full abatement). When abatements roll off, the gap closes.

In Marion County's older industrial corridors (West 16th Street, 38th & Sherman, the West-Washington corridor), the rolloff of 2015–2018-era abatements is closing gaps that opened in those years. Owners of older industrial facilities in the same corridors should see modest tax-rate relief as the gap closes.

How to read the abatement disclosure on a parcel

The Marion County property lookup shows abatement status for industrial parcels. The relevant fields:

Total AV — what the parcel would be taxed on absent any abatement
Abatement deduction — the deducted amount in the current year
Net taxable AV — what actually gets multiplied by the tax rate
Abatement year — which phase-year of the schedule

For 2026, look at the abatement year field. If it shows year 10 or 11, the parcel is rolling off or has rolled off. If it shows year 5–7, it's in active phase-down. If it shows year 1–4, it's in the early heavy-abatement years.

What to do

If you own non-abated industrial, track which abatements in your taxing district are rolling off. Each rolloff is incremental rate relief on your bill.
If you're considering an industrial site purchase, model the abatement schedule — what year it's in, what step-downs are remaining, and the implicit tax escalator over the hold period.
If you operate an abated facility, ensure CF-1 compliance is current. Revocation costs back-taxes and is hard to reverse.
If you're a fiscal stakeholder (school board, City-County Council member), the abatement rolloff schedule is in the Department of Metropolitan Development's annual abatement compliance report.
If you're an investor, abatement rolloffs in specific taxing districts can be a tailwind for non-abated parcels in those districts.
