What Is Nonprofit Exemption
Nonprofit exemption removes property from the tax rolls if it is owned and operated by a qualified charitable, educational, religious, or scientific organization. The property must be used exclusively for the organization's exempt purpose. Unlike government exemption, which applies to government-owned property, nonprofit exemption requires the organization to prove both ownership and charitable use annually in most states.
The key phrase is "exclusively for exempt purposes." A nonprofit that rents out part of its building to a for-profit tenant, or that uses space for commercial activity unrelated to its mission, jeopardizes the exemption. Assessors scrutinize this requirement closely during appeals.
Eligibility Requirements
Most states require nonprofits to hold 501(c)(3) status from the IRS, though some states accept other designations. Requirements vary by jurisdiction, but generally include:
- Current IRS determination letter showing 501(c)(3) status
- Articles of incorporation and bylaws demonstrating charitable purpose
- Proof that the organization operates exclusively for exempt purposes
- Property used directly for the organization's charitable mission, not held for investment or future expansion
- Annual filing or renewal of exemption claim, typically due between February and June depending on your state
Many assessors deny exemption claims because organizations miss filing deadlines. Some states require renewal every year; others every three years. Check your local assessor's office for specific deadlines in your jurisdiction.
How Assessors Evaluate Nonprofit Claims
When you appeal a nonprofit exemption denial at a board of review hearing, the assessor uses the same appraisal methods applied to taxable property to establish the property's fair market value. This creates a baseline showing what the exemption would save the organization annually.
The assessor then challenges the exemption on two fronts:
- Ownership. Is the property legally owned by a qualifying nonprofit entity?
- Use test. Is the property used exclusively for the charitable purpose described in the exemption application? Partial commercial use, even 10 to 15 percent, can trigger denial.
Comparable sales analysis does not apply to exemption appeals. The assessor is not trying to prove value; they are trying to prove the property fails to qualify based on use or ownership. Bring documentation of your organization's programs, revenue sources, and how the building supports those programs.
Board of Review Hearings
If your exemption is denied, you have the right to a board of review hearing. Bring:
- Original IRS determination letter (not just a copy)
- Detailed floor plan showing how each area of the building is used
- Financial statements showing revenue from exempt activities versus any rental or commercial income
- Lease agreements for any tenant space, if applicable
- Minutes from board meetings discussing the property's use
The board will also consider whether the property is leased to the nonprofit or owned outright. Some states exempt only owner-occupied property. If your organization leases the building, the exemption application may be rejected regardless of how the space is used.
Common Questions
- Can a nonprofit lose exemption if it generates income from the property?
- Yes. If a nonprofit operates a thrift store, parking garage, or rental apartment in the building, that income-generating activity can result in partial or full loss of exemption. Some states allow a small amount of incidental revenue, but the property must be used primarily for the exempt purpose. Document what percentage of square footage or operational time goes to each use.
- What if our nonprofit is expanding into an adjacent building?
- Property held for future expansion does not qualify for exemption. The building must be in use for the charitable purpose right now. If you own a building but have not yet renovated it or moved operations there, the assessor will deny the exemption. Only apply once the building is actively being used.
- Do we need to file an exemption application every year?
- This depends on your state. Some require annual renewal; others require reapplication only if ownership or use changes. Contact your county assessor's office to confirm. Missing a filing deadline often results in loss of exemption, even if the organization still qualifies.
