Delaware County property owners are about to open the most consequential Form 11 mailing in years. Notices land in mailboxes by mid-May 2026, carrying the first county-level look at the DLGF cost-table reset that pushed statewide assessed values up roughly 12% in the 2025 cycle. For Muncie homeowners, the East Central Indiana commercial corridor along McGalliard Road, and landlords serving Ball State University's off-campus rental market, the AV that lands on this notice is the number that will drive the spring 2027 tax bill — and the only deadline that matters right now is the June 15, 2026 appeal cutoff.
This guide breaks down what's distinctive about Delaware County's 2026 assessment cycle, where Muncie owners tend to find appeal-worthy errors, and how to get a Form 130 in front of the county PTABOA before the office is buried under late-cycle filings.
What's Driving Delaware County AVs in 2026
The statewide cost-table reset is the dominant force, but three local factors compound it inside Delaware County.
1. Muncie's Recovering Sales Market
Median sale prices in Muncie have moved up against a long-flat baseline. Indiana's statewide spring 2026 housing market is up roughly 4% year over year on a $273,400 median, and Muncie's lower-priced inventory has seen percentage gains running ahead of that mark on smaller dollar bases. Translation: the assessor's trending window picked up real upward signal, and Form 11 will reflect it.
2. Ball State's Off-Campus Rental Concentration
The neighborhoods bordering Ball State — Riverside-Normal City, Westside, and the McKinley corridor — carry one of the densest student-rental footprints in Indiana. These parcels are routinely misclassified between owner-occupied and rental status, which changes both the homestead deduction eligibility and the circuit breaker cap tier (1% for homestead, 2% for non-homestead residential). A class-code error here can swing a tax bill by several hundred dollars per year.
3. The McGalliard and Tillotson Commercial Corridors
Delaware County's commercial AV base is heavily concentrated along a few arterials. The DLGF cost-table reset hits commercial improvement values harder than residential because the cost-multiplier adjustments compound across larger structures. C&I parcels in Muncie should expect AV movement in the same percentage range we documented for Marion County's commercial surge, even though the absolute dollar increases will be smaller.
Delaware County mails Form 11 notices in mid-May, not on a single fixed date. The 45-day appeal window starts running from your specific notice date. Do not assume June 15 is your deadline — check the date printed on your Form 11 and add 45 days. If the notice arrives after May 1, your deadline is later than the statewide June 15 reference date.
What to Check on Your Delaware County Form 11
The five-item walkthrough in our statewide Form 11 guide applies. Three Delaware-specific items deserve extra attention.
Property Class Code
Misclassification is the single most common appeal-worthy issue we see in Delaware County. Verify:
- A Muncie single-family being lived in by the owner is coded 510 (one-family dwelling), not 511 (rental)
- A duplex on a single parcel is coded 520, not commercial
- An owner-occupied home with a basement apartment retains residential coding
A class-code change is typically a one-page correction at the assessor's office and does not require a full Form 130 if caught before the appeal window closes.
Homestead Status
If you bought a Muncie home in 2025 and never filed Form HC-10, your 2026 Form 11 will show no homestead deduction, no SB 1 supplemental homestead credit, and the wrong cap tier. The fix is filing Form HC-10 with the Delaware County Auditor before the spring tax deadline.
Land Value vs Improvement Value
Delaware's neighborhood codes drive land value separately from improvement value. A neighborhood-code change between cycles can spike land value alone, even when the house didn't change. If your land AV jumped more than 15% with no comparable spike in the improvement value, that's an appeal flag worth investigating.

Filing a Form 130 in Delaware County
Where to File
Form 130 is filed with the Delaware County Assessor's Office at the county courthouse, 100 W. Main Street, Muncie. Filings are time-stamped on receipt — mail submitted close to the deadline carries delivery risk, and we recommend hand-delivery or certified mail with return receipt for any submission in the final week of the window.
What to Include
A complete Delaware County Form 130 package should contain:
- Completed Form 130 (one per parcel)
- Stated grounds: market value challenge, condition, or assessment error
- Three to five comparable sales from the trending window — same neighborhood code where possible
- Photos documenting any condition issues (deferred maintenance, structural problems, functional obsolescence)
- For income property: rent roll and operating statement
- Optional but persuasive: a USPAP-compliant appraisal
The general Indiana property tax appeal guide walks through Form 130 evidence standards in more depth.
What Happens After Filing
The county PTABOA acknowledges the petition within roughly 30 days and may extend a written settlement offer based on the evidence package. Most Delaware County appeals settle without a formal hearing. If no settlement is reached, the PTABOA hearing is typically scheduled three to nine months out. PTABOA decisions can be escalated to the Indiana Board of Tax Review within 30 days of the written determination.
SB 1 and the Spring 2026 Bill
Delaware County homestead owners benefit from the SB 1 supplemental homestead credit on the spring 2026 bill — a 10% credit on net property tax owed, capped at $300 per homestead. Combined with the supplemental homestead deduction stepping from 35% to 40%, most Muncie homestead bills will see a measurable downward adjustment that partially offsets the AV increase coming through on the Form 11 notice for the following year's bill.
The two cycles do not net out. The SB 1 credit reduces the spring 2026 bill (based on 2024 pay 2025 AVs as adjusted). The Form 11 notice arriving in May 2026 sets the AV for the spring 2027 bill. If the AV increase on the Form 11 is larger than the SB 1 credit savings, the net effect across both years is a higher tax bill.
Where Delaware County Sits on the State Picture
Delaware County is mid-pack on Indiana property tax rates and assessment equity. It does not appear among the most over-assessed counties in the state, but it also doesn't show the rapid AV-growth profile of the fastest-growing counties along the I-69 corridor. The 2026 cycle is a meaningful inflection point — the cost-table reset has compressed several years of underlying market movement into a single notice.
For owners considering whether the appeal effort is worth it, the rule of thumb is simple: every $10,000 of AV reduction on a Muncie homestead translates to roughly $80–$110 of annual tax savings depending on taxing district. A successful appeal pays back across multiple cycles since the new AV becomes the baseline for the next trending window.
