Churches do not usually pay federal income tax on rental income. Under Section 512(b)(3) of the Internal Revenue Code, rents from real property are excluded from unrelated business taxable income, so a church that leases its fellowship hall for weekend events or rents a building to a neighboring business generally owes the IRS nothing on that revenue. Several situations flip that result: carrying a mortgage on the rented property, bundling services with the lease, renting out equipment along with the space, operating a parking lot, tying rent to a tenant’s profits, or leasing to an entity the church controls. When any of those triggers apply, part or all of the rent becomes taxable at the flat 21% corporate rate.
The Default Rule: Real Property Rent Is Excluded
Section 512(b)(3) carves out a specific exclusion: all rents from real property are excluded from unrelated business taxable income. This holds regardless of whether the tenant’s use has anything to do with religion. A church can rent to a dance studio, a for-profit daycare, or another congregation and still keep the income tax-free.
The exclusion works because a basic lease keeps the church’s role limited to collecting rent and handling normal upkeep. The church isn’t running a business; it’s letting someone else use the space. Once the church starts doing more than acting as a landlord, the character of the income can change.
When Rental Income Becomes Taxable
The Property Carries Debt
This is the most common trigger. If a church has a mortgage or any other borrowing used to buy or improve rental property, the IRS treats the property as “debt-financed,” and a portion of the rental income becomes taxable as unrelated debt-financed income under Section 514.
The taxable share equals the ratio of average outstanding debt to the property’s average adjusted basis during the year. On a building with an average adjusted basis of $500,000 and average acquisition indebtedness of $250,000, the debt-to-basis percentage is 50%, so half the gross rental income is potentially taxable. The church can offset that half with 50% of the directly connected expenses.
There’s an important escape hatch. If 85% or more of the property’s use is devoted to the church’s exempt purpose, the entire property is out of the debt-financed rules. A church that uses its building for worship and ministry six days a week and rents it out one evening typically clears this threshold without difficulty.
Churches also get a generous break on land bought for future ministry. Most exempt organizations must begin using newly acquired neighboring land for exempt purposes within 10 years to avoid debt-financed treatment. Churches get 15 years, and the land doesn’t even need to be near existing church property.
The Church Provides Services Beyond Landlord Duties
Rental income loses its exclusion when the church supplies services that go beyond what a typical landlord provides. Maintaining common areas, collecting trash from shared spaces, and providing heat are fine. Trouble starts with services offered primarily for the tenant’s convenience: catering, maid service, event staffing, switchboard operation, setup crews, sound technicians.
The IRS has consistently held that this kind of arrangement is closer to running a hotel or event venue than to leasing property. In one well-known ruling, a university that leased its stadium to a professional football team and also furnished playing-field maintenance, dressing-room linens, and locker-room services was found to be providing substantial services, and the income lost its rental exclusion. The same logic reaches a church that rents its space for weddings and throws in the setup and technical staff.
Equipment Is Mixed With the Space
Section 512(b)(3) covers only real property. Rent for personal property, such as tables, chairs, sound systems, or kitchen equipment, is not excluded.
When a lease bundles real property and personal property, the treatment depends on how much of the rent is attributable to the equipment:
- 10% or less for personal property: the entire rent stays excluded.
- More than 10% but no more than 50%: only the real-property portion is excluded; the personal-property portion is taxable.
- More than 50% for personal property: the entire rent, including the real-property portion, loses the exclusion.
A fellowship hall lease that includes a full commercial kitchen, audio-visual gear, and furniture can cross the 10% line easily. Run the numbers before signing.
The Church Operates a Parking Lot
Parking revenue gets harsh treatment. The IRS and the Tax Court have held that parking-lot income does not qualify as rent from real property for the UBTI exclusion, on the theory that operating a parking facility involves providing services to occupants rather than leasing space. A church that charges the public for parking on weekdays is likely earning taxable unrelated business income, even without an attendant on site.
Rent Depends on the Tenant’s Profits
The exclusion disappears when rent is tied to a tenant’s income or profits. A flat monthly amount is fine. A fixed percentage of gross receipts is fine. But if the rent moves with the tenant’s net profits, the entire payment loses the exclusion.
The Tenant Is a Controlled Entity
If a church controls another entity, meaning it owns more than 50% of a corporation or holds more than 50% of the interests in a partnership, rent from that entity is treated specially under Section 512(b)(13). The rent is pulled into unrelated business taxable income to the extent it reduces the controlled entity’s net unrelated income. The rule stops churches from sheltering income by routing it through related organizations.
How the Tax Is Calculated
Taxable rental income is taxed at the flat 21% federal corporate rate.
Before the tax is figured, the church subtracts a $1,000 specific deduction from its total unrelated business taxable income. A diocese or convention of churches gets a separate $1,000 deduction for each local parish or unit, capped at that unit’s gross unrelated business income. A church with modest taxable rent may owe little or nothing after the deduction.
If the church expects to owe $500 or more for the year, it must make quarterly estimated payments using the Form 990-W worksheet. Missing those payments triggers underpayment penalties on top of the tax.
Filing Form 990-T
A church with $1,000 or more in gross income from unrelated business activities must file Form 990-T, the Exempt Organization Business Income Tax Return. The deadline is the 15th day of the fifth month after the end of the church’s tax year, which is May 15 for calendar-year churches.
On the return, the church can deduct expenses directly connected to the taxable rental activity. For a property used partly for worship and partly for rental, costs like utilities, insurance, depreciation, and mortgage interest must be split between the two uses. The IRS requires a reasonable and consistent method. Space-based allocation by square footage is generally accepted for occupancy costs. Time-based allocation fits salaries of staff who split duties between exempt and rental work. Allocating by dollar receipts from various activities is generally considered unreasonable. Whichever method you use, keep records that can substantiate it.
Penalties and the Risk to Exempt Status
A church that owes UBTI and fails to file Form 990-T faces a penalty of 5% of the unpaid tax for each month or partial month the return is late, up to 25%. For a return more than 60 days overdue, the minimum penalty is the lesser of the tax due or $525. A separate late-payment penalty of 0.5% per month applies to unpaid tax, also capped at 25%.
The larger risk is to the exemption itself. The IRS has stated that earning too much unrelated business income can jeopardize a 501(c)(3) organization’s exempt status. No bright-line percentage triggers revocation, but if commercial activity starts to look like the church’s primary function rather than an incidental sideline, the IRS can act. Losing exempt status affects not only the church’s own taxes but also donors’ ability to claim charitable deductions.
State Property Tax Is a Separate Question
Federal income tax is only half the picture. Most states exempt church property from local property taxes, but those exemptions typically require the property to be used exclusively or primarily for religious purposes. Renting to for-profit tenants, even occasionally, can cause a partial or complete loss of the property tax exemption. Some states revoke the exemption for any commercial use; others apply a primary-use test that tolerates minor rentals. Because property tax bills on commercial real estate can be substantial, a church considering a long-term lease to a commercial tenant should check its state’s rules before signing. The property tax hit on part of a building can easily outweigh the rent.
