Tippecanoe County is one of Indiana's most distinctive property markets: a roughly 185,000-resident county anchored by Purdue University, paired with a Lafayette industrial base that includes Subaru, Wabash National, and Caterpillar suppliers. Property owners in Lafayette, West Lafayette, Battle Ground, and the surrounding townships are about to receive their 2026 Form 11 Notices of Assessment, which Tippecanoe County mails by the end of April.
The local effective property tax rate sits around 0.64% of market value, but the level masks a more important story for 2026: the DLGF cost-table reset and the largest year-over-year statewide AV growth in over a decade are landing on top of a West Lafayette rental market that has been recalibrating since pandemic-era enrollment shifts.
The 2026 Tippecanoe County Budget Order was issued January 15, 2026 by the DLGF, certifying tax rates and levies. Your Form 11 notice will reflect the new gross AV; your spring 2026 tax bill will apply that AV against the certified rate plus the new SB 1 $300 homestead credit.
Why Tippecanoe County's Form 11 Notice Matters More This Year
Three things converge to make 2026 a meaningful year for Tippecanoe property owners.
1. The Cost-Table Reset
The DLGF's 2025 cost-table update drove material increases in residential and commercial improvement values across Indiana. Statewide, AVs rose meaningfully — Tippecanoe is exposed both on the residential side (Lafayette and West Lafayette housing stock) and on the commercial side (Wabash Avenue corridor, Sagamore Parkway, the Purdue Research Park).
2. SB 1 Goes Live on Bills
The new 10% supplemental homestead credit, capped at $300, hits Tippecanoe County homestead bills for the first time on the spring 2026 installment due May 10. The supplemental homestead deduction also moves from 35% to 40% in 2026. For owners who haven't filed Form HC-10 on their primary residence, these benefits are forfeited — and West Lafayette has one of the highest rates of out-of-state buyer turnover in the state because of Purdue.
3. Business Personal Property Exemption Doubles
The Indiana business personal property exemption rises to $1M in 2026 and $2M in 2027. For the dense small-business ecosystem around Purdue and the Lafayette industrial corridor, this is a real planning trigger — particularly for spinout startups, professional services, and small industrial suppliers operating below the new threshold.
West Lafayette: A Distinctive Rental Submarket
Purdue's roughly 50,000 students concentrate housing demand in West Lafayette, a market that behaves more like a college-town real estate ecosystem than a typical Indiana submarket. Three Tippecanoe-specific assessment dynamics owners should watch on the 2026 Form 11:
Rental Class Code Drift
A duplex or small multi-family parcel coded as residential (1-4 units, class 5xx) faces the 2% cap rather than the 3% commercial cap, but only if it remains residentially classified. Conversion of single-family homes to student rentals sometimes triggers class-code reviews — verify your record card.
Homestead vs Non-Homestead
A West Lafayette property occupied by an absent owner or rented to students cannot claim the homestead deduction or the new SB 1 supplemental credit. If your Form 11 lists a homestead deduction on a parcel that is no longer owner-occupied, the situation will catch up with you — and the recapture provisions are not friendly. The statewide homestead guide walks through eligibility.
Income Approach for Larger Multi-Family
For parcels with 5+ units (apartment buildings serving Purdue), assessors increasingly lean on the income approach. If your assessor's vacancy or expense assumptions are out of step with your actual operating statement, an income-approach appeal can produce material reductions.
Lafayette: Industrial Base Meets Cost-Table Reset
Lafayette's east side carries a substantial industrial base — Subaru of Indiana Automotive, Wabash National, and a chain of suppliers running along Sagamore Parkway and out toward I-65. The 2026 cost-table updates affect this property type heavily because:
| Property type | 2026 cost-table sensitivity |
|---|---|
| Light manufacturing (class 415) | High — steel-frame and tilt-up cost factors updated |
| Heavy manufacturing (class 470) | High — process building factors moved |
| Warehouse/distribution (class 410) | Moderate — well-tracked recent construction |
| Office (class 320) | Moderate — slow demand may justify obsolescence argument |
| Retail (class 426) | Variable — high-vacancy parcels may warrant appeal |
For commercial owners, the 3% cap sets a ceiling but doesn't shield against cost-driven AV growth pushing more parcels above the cap and increasing the absolute cap loss.
Verifying Your 2026 Form 11
When the notice arrives in your mailbox in late April, walk through the same five checks our Form 11 statewide guide recommends — but layer in these Tippecanoe-specific items:
- Township assignment: Wabash, Fairfield, Wea, Tippecanoe, Sheffield, Shelby, Jackson, Perry, Tippecanoe — verify your parcel's township
- School corporation: Tippecanoe School Corporation, Lafayette School Corporation, and West Lafayette Community School Corporation each have different rates
- City/town code: Lafayette, West Lafayette, Battle Ground, Dayton, Otterbein, and Shadeland each layer municipal rates on top of base district rates
- Property class code: especially for rental-converted single-family or owner-occupied conversions
- Land acreage: agricultural land at the DLGF 2026 base rate of $2,120/acre with productivity adjustments

When an Appeal Is Worth Filing
The statewide appeal guide walks through the mechanics. In Tippecanoe County specifically, three patterns produce the highest success rates:
- Out-of-trend AV jumps: a Form 11 showing 18%+ AV growth on a property that has not been improved since the prior cycle is worth a comparable-sales review
- Class-code mismatches: any rental parcel showing a residential homestead deduction, or any homestead showing rental class
- Documented obsolescence on commercial: high-vacancy retail along older corridors, functionally obsolete office space, or industrial parcels with deferred plant investment
For parcels where the AV-vs-comps gap supports a reduction, Tax Appeal Automation builds the Form 130 + evidence package on contingency.
Filing Logistics
Tippecanoe County's Assessor's Office at 20 N 3rd Street in Lafayette accepts Form 130 filings in person, by mail (postmark date controls), and through the Beacon online portal. Online filings carry the lowest risk because they are time-stamped on receipt.
After filing, expect:
- 30-day acknowledgment from the County Assessor
- 60–90 day informal contact for parcels where written evidence supports a settlement
- 4–8 month hearing in front of the Tippecanoe PTABOA if no settlement
- 30-day post-decision window to escalate to the Indiana Board of Tax Review if the PTABOA outcome is unfavorable
