Howard County is one of the clearest illustrations in Indiana of how a heavy industrial tax base concentrates risk. Kokomo, the county seat, has been an automotive manufacturing hub for more than a century — Stellantis (formerly Chrysler) and its supplier network anchor the county's commercial-industrial AV. When that base moves, the county's school, city, and library budgets move with it. The 2026 cycle layers SB 1 on top of that structural reality, and the result for Kokomo property owners is meaningfully different from how the same statewide changes land on a residential-only county.
The Industrial Base Reality
In counties where one or two large industrial taxpayers represent a substantial share of the tax base, every assessment cycle is a high-stakes negotiation. Industrial AV doesn't move smoothly with residential market trends — it moves with depreciation schedules, capital investment cycles, plant retoolings, and periodic appeals. Howard County's recent decade tracks this clearly: AVs grow steadily during plant investment periods and flatten or contract during shutdowns.
For homestead owners in Kokomo, this matters because school and city tax rates are calculated against the total AV base. When industrial AV softens, residential rates rise to maintain the levy — and when industrial AV grows through new investment, residential rates ease.
Industrial-heavy counties are rate-sensitive, not AV-sensitive, for homesteads. A Kokomo homeowner watching Stellantis investment news is, in effect, watching their own future tax rate. New plant investment broadens the AV base and pushes rates down; plant contraction does the opposite.
What SB 1 Changes for Kokomo in 2026
Three SB 1 provisions reshape the 2026 bill:
- The new 10% supplemental homestead credit, capped at $300, applies directly to spring 2026 bills
- The supplemental homestead deduction rises from 35% to 40% of remaining AV after the standard deduction
- The business personal property exemption rises to $1M in 2026 and $2M in 2027
The third provision matters disproportionately in Kokomo. The county's Tier 1 supplier base — small to mid-sized manufacturers feeding the larger plants — historically held BPP filings in the $100K–$1M range. The new $1M floor eliminates filing burden for many of these businesses while removing a meaningful slice of the county's small-business BPP roll. In aggregate, that's a modest base contraction that gets absorbed by the rest of the AV base.
What to Check on Your Howard County Form 11
The general Form 11 walkthrough applies. Howard-specific items worth flagging:
School Corporation Assignment
Howard County is split across Kokomo School Corporation and several smaller districts (Eastern Howard, Western, Northwestern, Taylor). Rate variation between these districts is substantial. Confirm the school corporation listed on your Form 11 matches your physical address.
Class Code
Kokomo has a deep stock of mid-century single-families converted to rentals. A homestead miscoded as a rental loses the 1% cap, the standard and supplemental homestead deductions, and the new SB 1 $300 credit. The combined error can double a tax bill at the same AV.
Industrial-Adjacent Residential
Homes in immediate proximity to active industrial parcels sometimes carry condition or environmental adjustments that need to be re-verified each cycle. If your home sits within a few blocks of an active plant and your AV jumped without local sales support, this is a defensible appeal angle.
How the 2026 AV Cycle Looks Statewide vs. Howard
The statewide picture coming out of the 2025 DLGF base-cost adjustment removal was double-digit gross AV growth across most counties. The 2026 cycle is the first where that one-time reset is absent and where ordinary market trending drives the move.
For Kokomo specifically, the 2024 sales data that informed 2026 valuations showed continued single-digit appreciation in the residential core — consistent with broader Indiana 2026 housing patterns of moderating prices and rising inventory. That softer trend means the 2026 Form 11 should carry less of a sticker shock than the 2025 notice did.
Appeal Calculus in an Industrial County
The Form 130 appeal process in Howard County mirrors the statewide framework. A few local notes:
- Filing destination: Howard County Assessor's Office, Kokomo
- Online filing: available through the county portal
- Comparable sales: residential appeals should pull from the same neighborhood code and same school corporation
- Industrial appeals: usually involve professional appraisal and protracted PTABOA timelines — these are not DIY filings
For homestead and small commercial appeals, the practical filing window mirrors the statewide pattern: Form 11 in late April, decision to appeal by mid-May, filed Form 130 by early June.

| Appeal deadline (Form 130) | June 15, 2026 (or 45 days after mailing) |
The Stellantis Question
Any honest discussion of Howard County property tax has to acknowledge that the county's revenue stability is entangled with the future of the Stellantis footprint. Plant investment decisions, EV transition timelines, and supplier base shifts all flow through to AV — which flows through to tax rates — which flows through to every homeowner's bill. The good news for 2026: the SB 1 homestead credits and deduction expansions cushion individual bills against rate movements caused by the broader industrial base.
For owners who want to understand their parcel's exposure to industrial-base shifts, Property Lookup shows how the parcel's AV compares to neighborhood medians and how it has trended over recent cycles. If the trend doesn't match nearby comparables, the gap is appealable through Tax Appeal Automation.
Making the Most of 2026
For a typical Kokomo homestead with a $150,000 gross AV:
- Standard homestead deduction reduces AV
- 40% supplemental homestead deduction (up from 35%) reduces further
- Mortgage deduction (if applicable) reduces further
- Net AV multiplied by combined district rate produces gross tax
- The 1% homestead cap may bind, capping gross tax
- The new SB 1 $300 supplemental credit applies after cap
- Spring installment due May 11; fall installment due November 10
Compared with the same parcel under 2025 rules, the 2026 bill is meaningfully lower at the same AV — assuming homestead status is intact. That assumption is the single most important verification step.
