Yes, a 501(c)(3) can invest money. Federal tax law lets tax-exempt charities hold stocks, bonds, mutual funds, money market accounts, certificates of deposit, and real estate, and most of the income those investments generate is not taxed. The rules that matter are the ones around how the organization invests: board members owe fiduciary duties, certain leveraged investments trigger tax, insider deals can cost the organization its exemption, and private foundations face a separate layer of restrictions that public charities don’t.
What a Nonprofit Can Actually Hold
The investment menu for a 501(c)(3) looks a lot like the menu for any other investor. Operating cash and short-term reserves typically sit in FDIC-insured bank accounts or money market deposit accounts. Longer-term funds go into diversified portfolios of equities and fixed-income securities, often through mutual funds. Some organizations also hold real property, and a building used for operations counts as part of the investment portfolio even when it serves a programmatic role.
The reason to invest at all is practical. Donations and grants fluctuate; expenses don’t. Cash left in a non-interest-bearing account loses purchasing power to inflation every year. An invested reserve or endowment smooths cash flow and preserves the real value of the organization’s assets over time.
How Investment Income Is Taxed
One of the largest financial advantages of 501(c)(3) status is that most passive investment income falls outside the tax net. The statute governing unrelated business taxable income (UBTI) specifically excludes dividends, interest, annuities, royalties, most rents, and capital gains from the sale of investments, provided the organization isn’t acting as a dealer.1Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income A charity that earns $50,000 in stock dividends and $20,000 in bond interest owes no federal income tax on that money.
UBTI is what the IRS uses to tax income from activities that look like a regular business and have nothing to do with the charitable mission — running a commercial parking lot open to the public, for example, or selling unrelated merchandise through a gift shop.2Internal Revenue Service. Unrelated Business Income Tax Ordinary portfolio investing is not that. Buy stocks, collect dividends, sell for a gain, no tax.
The Debt-Financed Property Exception
There is one exception every board member should know about. If the organization borrows money to purchase an investment, part of the income from that investment becomes taxable. The taxable share is proportional to the acquisition debt outstanding against the property’s adjusted basis.3GovInfo. 26 USC 514 – Unrelated Debt-Financed Income Take out a mortgage covering 60% of a rental building’s purchase price, and roughly 60% of the rent becomes subject to UBTI.
This rule overrides the general exclusions for dividends, interest, rent, and capital gains whenever acquisition debt is in the picture.1Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income It catches nonprofits by surprise more often than any other investment tax issue. Get tax advice before financing an investment purchase.
Any exempt organization with $1,000 or more in gross unrelated business income must file Form 990-T, even after taking the $1,000 specific deduction that would zero out the tax on that first dollar of income.2Internal Revenue Service. Unrelated Business Income Tax
The Board’s Fiduciary Duty
Board members who oversee the money are fiduciaries. They owe the organization duties of care, skill, and loyalty. That means making informed decisions, diversifying appropriately, and keeping personal interests out of the process.
Nearly every state has adopted the Uniform Prudent Management of Institutional Funds Act (UPMIFA), which sets the legal framework for how charities invest and spend from institutional funds. Pennsylvania is the only state that has not. UPMIFA directs decision-makers to weigh eight factors together: general economic conditions, the effect of inflation or deflation, expected tax consequences, the role of each investment within the overall portfolio, expected total return, other resources the organization has available, the fund’s need to make distributions while preserving principal, and any special value a particular asset holds for the charitable mission.
These factors work as a whole, not as a checklist. A board that puts an entire endowment into a single stock might get lucky on returns but would still fail the diversification expectations built into the standard. What UPMIFA protects is a documented, thoughtful process, not a specific outcome.
Delegating to an Outside Advisor
Most boards don’t have investment professionals on them, and they don’t need to. Boards can hire an outside advisor to manage the portfolio day to day. Delegation does not shift the ultimate responsibility, though. The board still has to pick the advisor with care, define the scope of authority in writing, and monitor performance. Hiring someone and then losing track of what they do is not delegation.
Writing an Investment Policy Statement
An investment policy statement (IPS) is the document that turns fiduciary duty into operating instructions. It sets out investment goals, risk tolerance, target asset allocation, liquidity needs, and who has authority to do what. A useful IPS also specifies how often the portfolio gets reviewed and when it should be rebalanced.
Some organizations write mission-alignment criteria directly into the IPS — a health charity that excludes tobacco holdings, an environmental group that avoids fossil fuels. Screens like these are permissible as long as the portfolio still meets the prudent-management standard overall. Putting mission criteria in the policy makes them a documented decision rather than an ad hoc call, which is what protects the board if anyone questions the strategy later.
Conflicts of Interest and Insider Dealing
Investment decisions are where conflicts of interest most often show up. If a board member owns a financial advisory firm and the nonprofit’s assets end up under management at that firm at above-market fees, the organization has a real problem. Federal tax law prohibits any part of a 501(c)(3)’s earnings from benefiting private insiders, and the IRS treats that prohibition as foundational to exempt status.4Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations
The private benefit doctrine extends further, reaching arrangements that enrich third parties beyond what’s incidental to the organization’s public purpose.5Internal Revenue Service. Publication H – Private Benefit Under IRC 501(c)(3) An investment arrangement that pays a manager more than it should can raise concerns even without a formal insider relationship.
When a disqualified person — an officer, director, or anyone else with substantial influence over the organization — gets an economic benefit worth more than they gave in return, the IRS calls it an excess benefit transaction.6Internal Revenue Service. Intermediate Sanctions – Excess Benefit Transactions The disqualified person owes a 25% excise tax on the excess. If it isn’t corrected within the taxable period, a second-tier tax of 200% kicks in. Any manager who knowingly participated owes 10% of the excess benefit, capped at $20,000 per transaction.7Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
The practical safeguard is a written conflict-of-interest policy. The IRS asks about it on Form 990, including how conflicts get disclosed and managed. At a minimum, anyone with a potential conflict should disclose it and step out during discussion and voting on that item. Many organizations also send an annual conflict questionnaire to board members and senior staff.
Extra Rules for Private Foundations
Private foundations operate under tighter investment rules than public charities. Three of them matter most.
First, a foundation cannot make investments that show a lack of reasonable business care for its financial needs. No investment type is automatically off-limits, but the IRS applies heightened scrutiny to margin trading, commodity futures, short selling, oil and gas working interests, options, and warrants.8Internal Revenue Service. Private Foundation – Jeopardizing Investments Defined A foundation that makes a jeopardizing investment faces a 10% excise tax on the amount for each year the investment remains in jeopardy, and any manager who knowingly and willfully approved it owes 10% as well, capped at $10,000 per investment.9Office of the Law Revision Counsel. 26 USC 4944 – Taxes on Investments Which Jeopardize Charitable Purpose Failing to correct the situation triggers larger second-tier taxes.10Internal Revenue Service. Taxes on Jeopardizing Investments Public charities are not subject to this federal excise tax; state fiduciary law and UPMIFA govern their investment decisions instead.
Second, every private foundation pays a flat 1.39% excise tax on net investment income each year, no matter how prudently the money is managed.11Internal Revenue Service. Tax on Net Investment Income The single rate applies to tax years beginning after December 20, 2019, replacing the older two-tier system.12Internal Revenue Service. Tax on Net Investment Income of Private Foundations – Reduction in Tax Public charities do not owe this tax.
Third, foundations can make program-related investments (PRIs) that further the charitable mission directly rather than seek market returns. A PRI must satisfy three conditions: the primary purpose is to advance the foundation’s exempt activities, generating income or appreciation is not a significant purpose, and no purpose involves influencing legislation or political campaigns.13Internal Revenue Service. Program-Related Investments Below-market loans to nonprofit housing developers, equity in a social enterprise, or seed capital for a project that ordinary investors would pass on can all qualify. The test is whether a profit-motivated investor would take the same deal on the same terms; if yes, the IRS may find that returns were a significant purpose and disqualify the PRI. PRIs count toward the foundation’s required annual distributions and are not treated as jeopardizing investments.
Reporting Investment Activity to the IRS
Investment income has to be reported on the annual return. Public charities with gross receipts of $200,000 or more (or total assets of $500,000 or more) file Form 990; smaller ones may file Form 990-EZ. Private foundations file Form 990-PF regardless of size.14Internal Revenue Service. Publication 4839 – Annual Form 990 Filing Requirements for Tax-Exempt Organizations
On Form 990, investment income shows up in Part VIII (Statement of Revenue): dividends and interest on Line 3, royalties on Line 5, rental income on Line 6, and gains or losses from selling securities on Lines 7a through 7d.15Internal Revenue Service. Instructions for Form 990 Organizations with $1,000 or more in gross unrelated business income also file Form 990-T.2Internal Revenue Service. Unrelated Business Income Tax Private foundations report the 1.39% net investment income tax on Form 990-PF.11Internal Revenue Service. Tax on Net Investment Income Skipping these filings, even when no tax is owed, brings penalties, and three consecutive years of non-filing triggers automatic revocation of tax-exempt status.
