Cass County's 2026 property tax cycle is structured like every other Indiana county: spring installment due May 12, 2026 (Cass shifts a day from the May 10 baseline due to the calendar), Form 11 Notices of Assessment mailed in late April through mid-May, and a Form 130 appeal deadline 45 days from the Form 11 mailing or June 15, 2026 at the latest.
What's distinctive in Cass this year is the layering of the SB 1 supplemental homestead credit on top of a county where median tax bills are already among the lower in the state. For a Logansport homestead paying $1,200 a year, a $300 credit is a 25% bill reduction — proportionally larger than what high-rate counties see.
The January 15, 2026 deduction filing deadline has passed. New homestead, mortgage, age 65, disability, or veteran deductions filed after January 15 will not apply to the 2025-pay-2026 bill. They will apply starting with the 2026-pay-2027 cycle. If you bought a home in late 2025 and didn't file before January 15, your spring bill will be missing both the homestead deduction and the SB 1 credit.
What Changed for 2026
Three statewide changes hit Cass in the same cycle:
- SB 1 supplemental homestead credit: 10% off the homestead portion of the spring bill, capped at $300
- Supplemental homestead deduction step-up: 35% to 40% of post-standard-deduction AV
- DLGF cost-table reset: drove statewide AV growth around 12% in 2025
The first two are bill reducers; the third is an AV increase that — at constant rates — would push bills up. The net effect varies by parcel, but for most Cass homesteads the SB 1 credit and deduction step-up offset the AV growth.
The Bill Math for a Logansport Homestead
A typical Logansport homestead with a 2025 AV of $130,000 sits in the middle of the county's residential distribution. Walking through the 2026 calculation:
| Step | Calculation | Amount |
|---|---|---|
| Gross AV (2025) | — | $130,000 |
| Less standard deduction | $48,000 | $82,000 |
| Less supplemental (40%) | 40% × $82,000 | $49,200 |
| Net AV | $82,000 − $49,200 | $32,800 |
| Tax rate (illustrative) | $25 / $1,000 | — |
| Gross tax | $32,800 × 0.025 | $820 |
| 1% cap test | 1% × $130,000 | $1,300 (cap not binding) |
| Pre-credit tax | min(gross, cap) | $820 |
| SB 1 credit (10%, max $300) | 10% × $820 | $82 |
| Final spring + fall total | $820 − $82 | $738 |
This is illustrative — actual rates vary by Cass taxing district. The point is that a Cass homestead well below the cap sees the full benefit of both the deduction step-up and the SB 1 credit. Counties where most homesteads sit at the 1% cap (Marion, parts of Lake) get less benefit because the cap was already limiting their tax.
Cass County's Form 11 Cycle
Cass County assessment notices arrive in spring, typically reaching mailboxes by mid-May. The notice contains both the gross AV and the assessed value the assessor is proposing for the upcoming tax year, plus an estimate of what your tax bill will be.
The five items to verify the day your Form 11 arrives — covered in detail in the Form 11 day-of-arrival checklist:
- Year-over-year AV change: anything over 12–15% on a stable parcel deserves a closer look
- Land vs improvement split: neighborhood code changes can produce land-only spikes
- Improvement details: square footage, bedroom/bath count, finish quality
- Property class code: a homestead miscoded as 510 (rental) loses the 1% cap and the SB 1 credit
- Homestead/deduction flags: HSD, mortgage, age 65, disability — verify each is reflected
In Cass, the assessor's office sits at 200 Court Park, Room 305 in the Cass County Government Building in Logansport. Phone is (574) 753-7710. The office handles informal corrections faster than formal Form 130 appeals — call before filing if your issue is a CAMA data error rather than a valuation dispute.
Filing an Appeal in Cass
Cass County's PTABOA caseload is small relative to urban counties, which means Form 130 appeals here generally resolve in 3–6 months. The appeal mechanics, covered fully in the Indiana property tax appeal guide:
- File Form 130 with the Cass County Assessor's Office in Logansport
- Include 3–5 comparable sales from the trending window
- Photo documentation of any condition issues
- For income-producing property: rent roll and operating statement
- Filed by June 15, 2026 or 45 days from the Form 11 mailing date, whichever is later
The trending sales window for the 2026 assessment runs January 2024 through January 2025. Sales outside that window are still useful as context but won't carry the same evidentiary weight at PTABOA.
Logansport-Specific Items
Logansport sits in the eastern center of Cass County and accounts for the majority of the county's residential parcel count. A few items specific to Logansport-area properties:
School Corporation Boundaries
Cass includes Logansport Community School Corporation, Pioneer Regional School Corporation, and Caston School Corporation. Subdivisions near district boundaries occasionally get miscoded — verify your school corporation line on the Form 11.
Rate Variation Within Logansport
Inside Logansport city limits, owners pay a city rate component on top of county and school rates. Outside the city in unincorporated portions of Eel, Tipton, or Washington Township, the rate is meaningfully lower. Two parcels half a mile apart can have different total rates if one is inside the city line and one isn't.
River and Floodplain
Properties along the Wabash and Eel river floodplain may have lower land valuations reflecting the flood risk — but also have higher insurance pricing. When evaluating an AV that looks low for the lot size, check the floodplain status before assuming it's an under-assessment.

What to Do Now
If you missed the January 15 deduction filing deadline, the practical moves between now and the spring tax due date:
- Verify your homestead is on file — call the Cass County Auditor's office to confirm
- Pay the spring bill by May 12 — late payment penalty is 5% (10% after 30 days)
- Open your Form 11 the day it arrives and run the five-item checklist
- File Form 130 by June 15 if the AV looks unreasonable
For the AV evaluation, Property Lookup pulls Cass comparable sales by neighborhood code, and Tax Appeal Automation builds the Form 130 + evidence package for owners who'd rather not do the comp pull themselves.
