501(c)(3) Organization

A 501(c)(3) organization is an entity the IRS has recognized as exempt from federal income tax under section 501(c)(3) of the Internal Revenue Code because it is organized and operated exclusively for an exempt purpose, charitable, religious, scientific, literary, educational, and a few others. The name is simply the code subsection. Its practical importance to donors is that contributions to a 501(c)(3) are the ones that generally qualify for the charitable deduction, subject to rules set out separately. The category splits into two kinds of organization, and the split matters more than most donors realize.

To qualify, an organization must be both organized and operated for exempt purposes, with no part of its earnings benefiting private individuals (the prohibition on "private inurement"), only limited lobbying, and an absolute bar on intervening in political campaigns. Break the campaign rule and the exemption is at risk. Other subsections of 501(c) exempt other kinds of nonprofit, a 501(c)(4) social welfare organization, a 501(c)(6) business league, but donations to those are generally not tax-deductible. That is why "is it a 501(c)(3)" is the first question a donor asks about deductibility.

Every 501(c)(3) is classified as either a public charity or a private foundation, and the default is private foundation unless the organization qualifies as a public charity. Public charities are the familiar operating organizations, churches, schools, hospitals, and groups that draw broad public support; private foundations are typically funded by one family or company and make grants. Private foundations face their own excise taxes, a mandatory annual payout, and stricter self-dealing rules that public charities do not.

The classification also reaches the donor's tax result, which is where the distinction becomes concrete. Gifts to public charities are deductible against a higher share of income and, for long-term appreciated property, at full market value. Gifts to private foundations are deductible against a lower share of income, and for most appreciated property other than publicly traded stock the deduction is limited to the donor's cost basis rather than market value. The precise ceilings, the floor, the carryforward, and the substantiation rules all belong to the charitable contribution deduction; the point here is that the recipient's classification, not just the size of the gift, drives what the donor can deduct.

An organization becomes a recognized 501(c)(3) by applying to the IRS, usually on Form 1023 (a streamlined Form 1023-EZ is available to smaller applicants). Churches are treated as exempt automatically without applying, though many seek a determination letter anyway. Keeping the status requires filing the annual Form 990-series return; an organization that fails to file for three consecutive years has its exemption automatically revoked.

For a donor, the mechanics that matter are the recipient's status and its classification.

Consider a hypothetical donor giving closely held stock worth $50,000 that they bought for $15,000 and held more than a year. If the recipient is a public charity, the donor can generally deduct the full $50,000 market value and the $35,000 of built-in gain is never taxed. If the recipient is a private foundation, the deduction for that same closely held stock is limited to the donor's $15,000 cost basis, because appreciated property other than publicly traded stock given to a private foundation is deductible only at basis. The gift is identical; the recipient's classification changes the deduction by $35,000. Publicly traded stock is the exception, deductible at full value even to a private foundation. The overall percentage-of-income limits that then apply are governed by the charitable contribution deduction.

Pros

• Confirming 501(c)(3) status tells a donor the gift is to a deductible-eligible recipient, unlike gifts to most other nonprofit types.
• Public-charity status gives donors the most favorable deduction treatment, including full market value for long-term appreciated assets.
• The IRS maintains a public database of recognized organizations, so status is verifiable before giving.

Cons

• "Tax-exempt" does not mean "deductible": a 501(c)(4) or (c)(6) is exempt but gifts to it usually are not deductible, which is easy to conflate.
• Gifts to a private foundation carry lower deduction ceilings and, for most appreciated property, a basis limitation, so the recipient's classification can quietly reduce the benefit.
• An organization can lose its status by failing to file or by prohibited activity, so past recognition is not a permanent guarantee.
