Our complete list of Indiana deductions and exemptions mentions the nonprofit exemptions in a few short paragraphs, because for most homeowners they're background. But if you sit on the board of a church, a food pantry, a private school, or any other nonprofit that owns Indiana real estate, the exemption is not background — it's the difference between a $0 tax line and a bill that can consume a meaningful slice of your budget.
It is also not automatic. Unlike federal land at, say, Grissom Air Reserve Base, which is exempt by virtue of federal ownership, a nonprofit's exemption exists only if the organization claims it correctly, on the right form, by the deadline, and can defend how the property is actually used. Here's the whole system.
The legal test: ownership, occupancy, AND use
The core statute is IC 6-1.1-10-16: all or part of a building is exempt from property taxation if it is owned, occupied, and used for educational, literary, scientific, religious, or charitable purposes. The exemption generally extends to the land the exempt building sits on and personal property inside it.
All three prongs must be satisfied, and this is where applications die:
- Ownership — the property must be owned by the entity claiming the exempt purpose. A 501(c)(3) determination letter helps establish the character of the organization, but federal tax-exempt status alone does not decide Indiana property tax exemption.
- Occupancy — the organization must actually occupy the property. A vacant building "held for future ministry use" is a much harder case than an active one.
- Use — the property must genuinely be used for the exempt purpose, and Indiana caselaw applies a predominant use standard. Tax counsel at Faegre Drinker has chronicled how often the use prong decides these cases in Indiana exemption appeals involving churches.
Warning
The most expensive misconception in this area: "we're a nonprofit, so our property is exempt." Indiana exempts property used for exempt purposes, not organizations. A nonprofit that owns a rental duplex as an investment owes tax on it like any landlord.
Form 136: how you actually claim it
The exemption is claimed on Form 136 (State Form 9284), the Application for Property Tax Exemption, filed with the county assessor of the county where the property sits. The form and its instructions spell out the mechanics, and the DLGF's exemptions page is the state-level reference.
The essentials:
| Requirement | Detail |
|---|---|
| Deadline | On or before April 1 of the assessment year |
| Where | County assessor (two copies) |
| Fee | None |
| Attachments | Articles of incorporation, bylaws, recent financial statements, and a use breakdown for the land and each part of each building |
| Who decides | The county PTABOA reviews and approves or denies |
The April 1 deadline is the one to tattoo on the office calendar. Miss it and the property is taxable for that assessment year — full stop, regardless of how obviously exempt the use is. Law firms that litigate these cases publish annual reminders for a reason; Faegre Drinker's filing-deadline alert collects examples of organizations that lost a year of exemption to a late application.
Because the application runs to the PTABOA, a denial isn't the end: the notice of rejection comes with appeal rights on a clock. If your Form 136 is denied in whole or in part, treat the determination like any adverse assessment decision — our PTABOA vs. IBTR escalation guide maps the route upward.
Partial use: when only part of the building qualifies
Notice the statute's opening words: "all or part of a building." Indiana handles mixed-use nonprofit property with a proportional exemption, and Form 136 is built around it — that's why the application demands a use breakdown for each part of each building.
How the allocation works in practice:
- A building used entirely for worship, classrooms, and charitable programs → 100% exempt.
- A building where the organization uses most floors but leases a storefront to a commercial tenant → the exempt percentage reflects the exempt use; the commercial portion stays taxable. If 60% of the building serves exempt purposes, the exemption applies to 60%.
- Shared or time-split space gets allocated too — a gym used weekdays by the school and rented out commercially on weekends is a percentage conversation, and your documentation of the actual schedule is the evidence.
Be precise and honest in the breakdown. The percentage you claim on Form 136 is the percentage you'll be asked to defend, and an allocation that ignores a paying tenant is a classic path to a partial denial — or a later reassessment with penalties.
Tip
Parsonage-style questions, fellowship halls, storage buildings, parking lots, and vacant land attached to a campus each have their own treatment under the exemption chapter. When the campus has more than one building or use, walk the whole parcel against the statute before filing rather than claiming 100% by reflex.
Do you have to re-file every year?
No — but the answer isn't "never," either. Per the Form 136 instructions, the application must be re-filed every even year unless the property remains owned, occupied, and used for exempt purposes and continues to meet the statutory requirements (IC 6-1.1-10-16 among them) — in which case the exemption continues without re-filing. County assessors publish the same rule; Kosciusko County's not-for-profit exemption page is a representative statement of it.
The safe operating rule for a nonprofit board:
- Nothing changed? A properly granted exemption under the ownership-occupancy-use test generally carries forward.
- Anything changed? New ownership, a move, a new tenant, a change in how space is used, new construction, or an acquisition of additional property — file (or re-file) Form 136 by the next April 1. An exemption granted on yesterday's facts does not stretch to cover today's different ones.
- When in doubt, file. There's no fee, and a redundant application is infinitely cheaper than a lost year.
Why applications get denied
Recurring denial patterns, drawn from the statute's structure and the caselaw:
- Late filing — the April 1 deadline is unforgiving.
- Ownership/use mismatch — the exempt organization uses the building, but title sits in a different entity (a holding company, an individual donor) that doesn't independently qualify.
- Vacancy or speculative future use — property bought for eventual exempt use but not yet occupied and used for it.
- Commercial activity treated as incidental when it isn't — leases, cell tower income, event rentals that dominate the actual use of the space.
- Thin documentation — no use breakdown, missing financials, or an application that asserts conclusions instead of describing what happens in each room.
Verify the parcel before and after you file
Exemption decisions post to the parcel record like everything else. Verify your organization's parcels — assessed values, the exempt percentage actually applied, and the taxing district — with Property Lookup, both when you file and after the PTABOA acts. A granted exemption that never made it onto the tax roll produces a bill you shouldn't pay without a fight.
