Are all nonprofit organizations exempt from BIR income tax?

No. NIRC Section 30 exempts specific categories of nonstock, nonprofit corporations and associations — such as religious, charitable, educational, and civic organizations — but only on income related to the purpose for which they were organized. Income from unrelated property or profit-making activity is taxable.

What does 'unrelated trade or business' mean for a Section 30 organization?

It means any trade, business, or activity the exempt organization conducts for profit that is not substantially related to the exercise of the purpose or function that qualifies it for exemption — for example, a charitable foundation renting out commercial space or running a for-profit canteen open to the public.

Does it matter if the organization uses unrelated business income for its charitable programs?

No. The last paragraph of NIRC Section 30 taxes income from property or unrelated profit-making activity 'regardless of the disposition made of such income.' Even if 100% of the proceeds fund the organization's exempt purpose, the income itself remains taxable if the activity that generated it was unrelated to that purpose.

What tax rate applies to a Section 30 organization's unrelated business income?

Unrelated business income of an otherwise tax-exempt Section 30 organization is subject to the regular corporate income tax rate under NIRC Section 27, the same rate a taxable corporation would pay, computed and reported on the applicable BIR income tax return for that income.

Does earning unrelated business income cancel a Section 30 organization's tax exemption entirely?

Not automatically. Earning taxable unrelated business income does not by itself revoke a Section 30 certificate of tax exemption — the organization simply becomes liable for income tax on that specific unrelated income while remaining exempt on income related to its exempt purpose, unless the BIR separately finds it no longer meets the qualifying conditions.

Is a Tax-Exempt Nonprofit's Unrelated Business Income Still Taxed by the BIR? NIRC Section 30 Explained

A BIR-registered nonstock, nonprofit corporation exempt under NIRC Section 30 is not exempt from income tax on everything it earns — the last paragraph of Section 30 makes income from its properties or from any profit-making activity unrelated to its exempt purpose taxable, no matter what the organization does with that income afterward. This surprises many boards and treasurers who assume a Certificate of Tax Exemption covers all revenue once it’s approved.

What does Section 30 actually exempt? #

NIRC Section 30 lists specific categories of nonstock, nonprofit corporations and associations — religious, charitable, scientific, athletic, cultural, civic-league, labor, agricultural, and several others — and exempts each category from income tax, but only on income connected to the exempt purpose that qualifies it under the statute. Organizations covered under RMO No. 38-2019’s Certificate of Tax Exemption renewal process fall under this same Section 30 framework — the exemption is purpose-scoped, not a blanket exemption on every peso the organization collects.

What does the “last paragraph” of Section 30 say? #

A separate, closing paragraph of Section 30 exists specifically to prevent a tax-exempt organization from using its exempt status to shelter income earned from unrelated commercial activity. The provision is commonly quoted as follows:

“Notwithstanding the provisions in the preceding paragraphs, the income of whatever kind and character of the foregoing organizations from any of their properties, real or personal, or from any of their activities conducted for profit regardless of the disposition made of such income, shall be subject to tax imposed under this Code.”

Two elements of that text matter most in practice: it covers income “from any of their properties” (for example, rental income from a building the organization owns) as well as income from “activities conducted for profit,” and it applies “regardless of the disposition made of such income” — meaning the exemption inquiry stops at whether the activity was related to the exempt purpose, not at what the organization later did with the money.

What counts as an unrelated trade or business? #

An activity is “unrelated” for Section 30 purposes when it is not substantially related to the exercise of the function that justifies the organization’s tax exemption in the first place, even if the activity is conducted regularly and profitably. Common examples that trigger taxable unrelated business income for otherwise exempt organizations:

A religious or charitable foundation leasing commercial space in a building it owns to unrelated tenants
A civic or professional association running a for-profit canteen, gift shop, or parking facility open to the general public
An educational institution’s non-school commercial ventures unrelated to instruction (distinct from the school’s own tuition and education-related income, which follows the separate rules covered in Are Private Schools Tax-Exempt?)
Investment or rental income from property not used directly in the organization’s exempt activities

By contrast, membership dues, donations, grants, and revenue directly tied to carrying out the exempt purpose (tuition for a school, hospital fees for indigent patient care under a charitable hospital’s mission, etc.) generally remain within the exemption.

Worked example: a charitable foundation with a rented-out building #

A registered charitable foundation exempt under Section 30 owns a three-story building; it uses the ground floor for its own program offices and leases the second and third floors to unrelated commercial tenants for ₱1,200,000 a year in rental income. The foundation’s donation and grant income supporting its charitable programs remains exempt. The ₱1,200,000 in rental income from the leased floors, however, falls squarely under the last paragraph of Section 30 — it is income from the foundation’s property, unrelated to the direct conduct of its charitable programs — and is subject to the regular corporate income tax rate under NIRC Section 27, even though every peso of that rental income is ultimately spent funding the foundation’s charitable work.

Income source	Related to exempt purpose?	BIR tax treatment
Donations and grants for charitable programs	Yes	Exempt
Program service fees tied to charitable mission	Yes	Exempt
Rental income from leased commercial space	No	Taxable at regular corporate rate

Summary #

Section 30 tax exemption is activity-based, not organization-wide: a qualified nonstock, nonprofit corporation stays exempt on income tied to its exempt purpose, but the law’s own last paragraph pulls income from unrelated property or profit-making activity back into the regular corporate tax base, regardless of how that income is later spent. Organizations relying on a Section 30 exemption should review each revenue stream against this test individually — see BIR Certificate of Tax Exemption for Nonprofit Organizations for the exemption renewal process itself, and Cooperatives’ BIR Tax Exemption for how a related exemption category applies a similar related-vs-unrelated distinction.
