Vigo County tax bills go out one time a year by April 15, and Form 11 assessment notices typically arrive in Terre Haute mailboxes around the same window. For 2026 the timing matters more than usual: the DLGF cost-table reset has driven statewide assessed values up roughly 12%, and Terre Haute's lower median sale prices mean that even modest dollar movements show up as outsized percentage changes on Form 11. The notice you open this spring is the number that drives your spring 2027 tax bill — and the Form 130 appeal window opens the day the notice is dated.
This guide covers what's distinctive about Vigo County's 2026 cycle, how Indiana State University's footprint shapes the local assessment landscape, and the practical mechanics of getting an appeal filed before the June deadline.
What's Different About 2026 in Vigo County
The cost-table reset is statewide, but its expression is local. Vigo County brings three specific dynamics into the 2026 cycle.
1. Low-Dollar Base, High-Percentage Movement
Terre Haute's median home value is well below the Indiana statewide median of $273,400. With a smaller dollar base, every dollar of AV change shows up as a larger percentage. A $15,000 AV increase on a $90,000 baseline reads as a 17% move, which can feel alarming on a Form 11 even when the underlying dollar amount is modest. The right reference point isn't the percentage on the notice — it's the comparable sales in your neighborhood code.
2. Indiana State University's Off-Campus Rental Footprint
The neighborhoods bordering ISU — particularly along Wabash Avenue, 6th Street, and the corridors south of campus — carry one of the densest student-rental concentrations in west-central Indiana. Like other university towns, Vigo County sees frequent class-code drift between owner-occupied (510) and rental (511) coding. A misclassification flips your circuit breaker cap from 1% to 2% and disqualifies the homestead deduction. This is the single most consequential line item to verify on a Vigo County Form 11.
3. The Industrial and Logistics Base
Vigo County's commercial and industrial AV is concentrated in a relatively small number of large parcels — distribution facilities, manufacturing along the Wabash River corridor, and the medical complex around Union Hospital. The DLGF cost-table reset compounds across larger structures, so C&I owners should expect AV movement consistent with what we documented in Marion County's commercial assessment surge, even if the absolute dollar gains are smaller per parcel.
Vigo County Filing Calendar

| Form 11 notice mailing | By mid-April 2026 |
| Tax bill mailing | By April 15, 2026 |
| Form 130 appeal deadline | 45 days after notice date (or June 15, whichever is later) |
| Spring tax installment due | May 11, 2026 |
| Fall tax installment due | November 10, 2026 |
| PTABOA hearings | Typically 3–9 months after filing |
Vigo County mails Form 11 in mid-April and the tax bill on or about April 15. Two different documents. The tax bill is for the current year (2025 pay 2026) and reflects last year's AV. The Form 11 is for next year (2026 pay 2027) and is the one you can appeal. Don't confuse the two — the appeal deadline runs from the Form 11 date, not the tax bill date.
What to Check on Your Vigo County Form 11
Use the statewide Form 11 walkthrough for the general process. Three Vigo-specific items deserve focused attention.
Property Class Code
Verify:
- Owner-occupied single-family is 510, not 511 (rental)
- A duplex on one parcel is 520
- A converted carriage house or detached ADU does not bump the parcel into commercial coding
- Parcels with a combined home + farmland use are coded correctly between residential and ag
Class-code corrections are typically resolved at the assessor's office without a full Form 130 if caught early in the window.
Homestead Filings
Bought in Terre Haute during 2025? Confirm the Vigo County Auditor has your Form HC-10 on file. Without it, your 2026 Form 11 will not show the homestead deduction, the SB 1 supplemental homestead credit won't apply on the spring 2026 bill, and your cap tier will default to 2% rather than 1%.
Land vs Improvement Split
Vigo's land valuations follow neighborhood codes that can shift between cycles. A spike in land AV without a corresponding move in improvement AV is an appeal flag worth investigating. Compare your land AV per square foot against three or four nearby parcels with similar lot sizes — significant divergence is grounds for a written correction request.

Filing a Form 130 in Vigo County
Where to File
Form 130 is filed with the Vigo County Assessor's Office at the county courthouse, 191 Oak Street, Terre Haute. The office accepts in-person, mailed, and (for some parcel types) online submissions. Filings are time-stamped on receipt — meaning a postmark date does not protect a late delivery. For any submission in the final week of the window, hand-delivery or certified mail with return receipt is the only safe option.
What to Include
A complete Vigo County Form 130 package should contain:
- Completed Form 130 (one per parcel)
- Stated grounds: market value, condition, or assessment error
- Three to five comparable sales — same neighborhood code where possible
- Photos documenting condition issues
- For income property: rent roll and operating statement
- Optional: USPAP-compliant appraisal
The general Indiana property tax appeal guide covers the evidence standards that PTABOA panels weight most heavily.
What Happens After Filing
The PTABOA acknowledges the petition and may extend a written settlement offer. Most Vigo County appeals settle on written evidence without a formal hearing. Hearings typically schedule three to nine months after filing. 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
Vigo County homestead owners receive the SB 1 supplemental homestead credit on the spring 2026 bill — a 10% credit on net property tax owed, capped at $300 per homestead. The supplemental homestead deduction also steps from 35% to 40% in 2026. Together, these adjustments produce a measurable downward shift on the spring 2026 bill that partially offsets the AV increase landing on the Form 11 notice for the following year's bill.
For a Terre Haute homestead with a moderate AV, the practical effect is that the spring 2026 bill will likely come in below the spring 2025 bill — but the spring 2027 bill (driven by the Form 11 you're about to receive) is the cycle to plan for. The appeal window is the only mechanism to influence that 2027 bill.
Vigo County in the Statewide Picture
Vigo County sits in the lower half of Indiana property tax rates on a per-AV basis but has historically shown elevated cap-loss exposure as a percentage of levy because of the relatively high ratio of cap-bound parcels to total parcels. The 2026 AV increases will pull additional parcels into cap-bound territory — meaning more Terre Haute homesteads will hit the 1% ceiling, and the appeal calculus shifts. For cap-bound parcels, an AV reduction reduces the tax bill at the 1% cap rate (1¢ per $1 of AV reduction), which is a smaller payoff than for non-cap-bound parcels.
That said, Vigo's commercial and industrial parcels — generally not cap-bound — see the full tax-rate benefit of every AV dollar reduced. A successful C&I appeal in Terre Haute can yield $30+ of annual tax savings per $1,000 of AV reduction.
