Yes, a 501(c)(3) can invest money. Federal tax law lets tax-exempt charitable organizations hold stocks, bonds, mutual funds, real estate, and other investment assets, and most of the income those investments generate is not taxed. The rules that matter are about how you invest: borrowed money changes the tax picture, private foundations face extra restrictions, and the board carries fiduciary duties that apply to every dollar in the portfolio.
What a 501(c)(3) Can Invest In
A 501(c)(3) has access to the same investment options as any other investor. Common holdings include stocks and bonds, mutual funds, money market funds, certificates of deposit, and real estate. Working capital and operating reserves typically sit in FDIC-insured bank accounts or money market deposit accounts. Longer-term funds often go into diversified portfolios of equities and fixed-income securities. Some organizations also hold real property, including buildings used for their own operations.
The reason to invest is practical. Donations and grants fluctuate; bills don’t. A reserve fund or endowment invested prudently produces income that smooths out cash flow and protects against inflation. A dollar sitting in a non-interest-bearing account loses purchasing power every year. For most organizations with meaningful reserves, investing is a basic piece of responsible financial management rather than an optional extra.
How Investment Income Is Taxed
One of the biggest advantages of 501(c)(3) status is that most passive investment income is not taxed. Federal law specifically excludes dividends, interest, annuities, royalties, and most rents from unrelated business taxable income (UBTI). Capital gains from selling investments are also excluded, as long as the organization isn’t operating as a dealer in property.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 applies when an exempt organization earns income from a trade or business it regularly conducts that has no substantial connection to its charitable mission.2Internal Revenue Service. Unrelated Business Income Tax Running a gift shop that sells unrelated items, operating a commercial parking lot, or providing paid services to the general public can all generate UBTI. Ordinary passive investment income generally stays outside that definition.
The Debt-Financed Property Trap
The passive-income exclusion has one significant exception. If a nonprofit borrows money to purchase an investment asset, a portion of the income from that asset becomes taxable. The taxable share is proportional to the amount of outstanding debt relative to the property’s adjusted basis.3GovInfo. 26 USC 514 – Unrelated Debt-Financed Income If a charity takes out a mortgage to buy a rental building and the loan covers 60% of the purchase price, roughly 60% of the rental income is subject to UBTI.
This rule catches organizations off guard more often than any other investment tax issue. It overrides the general exclusions for dividends, rent, interest, and capital gains whenever acquisition debt is involved.1Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income If your organization is considering leveraged investments, get tax advice before signing anything.
When You Have to File a 990-T
Any exempt organization with $1,000 or more in gross income from an unrelated business must file Form 990-T to report that income and calculate any tax owed.2Internal Revenue Service. Unrelated Business Income Tax A $1,000 specific deduction is allowed when computing UBTI, so an organization with exactly $1,000 in gross unrelated business income would owe no tax after the deduction, but the return still has to be filed.1Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income
Extra Rules for Private Foundations
Private foundations operate under a stricter investment framework than public charities. Three rules shape how they invest.
Jeopardizing Investments
A private foundation cannot invest its assets in ways that show a lack of reasonable business care for its financial needs. No category of investment is automatically prohibited, but the IRS applies heightened scrutiny to margin trading, commodity futures, short selling, oil and gas working interests, options (puts, calls, and straddles), and warrants.4Internal Revenue Service. Private Foundation – Jeopardizing Investments Defined The test is whether the managers exercised good judgment and considered both the long-term and short-term financial needs of the foundation before committing funds.
The penalties are layered. The foundation itself owes a 10% excise tax on the amount invested, applied for each year (or partial year) the investment remains in jeopardy. A manager who knowingly and willfully participated also owes a 10% tax, capped at $10,000 per investment.5Office of the Law Revision Counsel. 26 USC 4944 – Taxes on Investments Which Jeopardize Charitable Purpose If the investment isn’t removed from jeopardy within the correction period, an additional 25% tax hits the foundation, and any manager who refused to correct owes 5%, capped at $20,000.6Internal Revenue Service. Taxes on Jeopardizing Investments
Public charities are not subject to this federal excise tax. Their investment decisions are governed by state fiduciary duty law instead.
The 1.39% Excise Tax on Net Investment Income
Every private foundation pays a flat 1.39% excise tax on its net investment income each year, regardless of how prudently the money is invested.7Internal Revenue Service. Tax on Net Investment Income It applies to dividends, interest, rents, royalties, and capital gains, minus allowable expenses. Public charities do not owe this tax.
Program-Related Investments
Private foundations can also make investments that advance their charitable mission directly rather than seeking financial returns. These program-related investments (PRIs) must meet three requirements: the primary purpose is to further the foundation’s exempt activities, generating income or appreciation is not a significant purpose, and influencing legislation or political campaigns is not a purpose. A below-market loan to a nonprofit housing developer or seed capital for a project a profit-motivated investor would pass on can qualify. PRIs count toward the foundation’s required annual distributions and are not treated as jeopardizing investments.8Internal Revenue Service. Program-Related Investments
What the Board Owes the Organization
Board members who oversee investments are fiduciaries. They owe the organization a duty to manage its assets with care, skill, and loyalty: make informed decisions, diversify appropriately, and never put personal interests ahead of the mission.
Nearly every state has adopted the Uniform Prudent Management of Institutional Funds Act (UPMIFA), which sets the legal framework for how charitable institutions invest and spend from endowment funds. Pennsylvania is the sole holdout. UPMIFA requires decision-makers to weigh eight factors when investing institutional funds:
- General economic conditions
- The possible effect of inflation or deflation
- Expected tax consequences of investment decisions
- The role each investment plays within the overall portfolio
- Expected total return from income and appreciation
- Other resources available to the organization
- The fund’s need to make distributions and preserve capital
- Any special relationship or value an asset has to the organization’s mission
These factors are meant to be considered together, not run through as a checklist. A board that loads an entire endowment into a single stock might post strong returns one year and still fail the diversification and risk expectations embedded in the standard. What UPMIFA asks for is a thoughtful, documented process, not a guarantee of results.
Hiring an Outside Investment Manager
Most nonprofit boards aren’t staffed with investment professionals, and they don’t need to be. A board can delegate day-to-day management to an outside advisor or firm. Delegation doesn’t erase the board’s responsibility, though. The board still has to pick the advisor carefully, define the scope of authority in writing, and monitor performance over time. Hiring a professional and then ignoring what they do is not prudent delegation, and the board keeps liability for that gap.
Writing an Investment Policy Statement
An investment policy statement translates fiduciary duty into operating guidelines. A workable IPS spells out the organization’s investment goals, risk tolerance, target asset allocation, liquidity needs, and the roles of everyone involved in investment decisions. It should also say how often the portfolio will be reviewed and when the allocation should be rebalanced.
Some organizations build mission-alignment screens into the IPS, excluding industries or companies that conflict with their work. A health-focused charity might exclude tobacco stocks; an environmental group might avoid fossil fuel holdings. These screens are permissible so long as the overall portfolio still meets the prudent-management standard. Putting those decisions in the IPS makes them deliberate, which is exactly the kind of documentation that protects a board if the strategy is questioned later.
Keeping Insiders Out of the Deal
Investment decisions are fertile ground for conflicts of interest. If a board member owns a financial advisory firm and steers the nonprofit’s assets to that firm at above-market fees, the organization has a serious 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.9Internal Revenue Service. Exemption Requirements – 501(c)(3) Organizations
The private benefit doctrine reaches further. Even benefits flowing to people who aren’t insiders can jeopardize exemption if those benefits are more than incidental to the organization’s public purpose.10Internal Revenue Service. Publication H – Private Benefit Under IRC 501(c)(3) An investment arrangement that enriches a third-party fund manager at the charity’s expense can raise private-benefit concerns even if the manager has no formal relationship with the board.
Excess Benefit Transactions
When a disqualified person (generally an officer, director, or anyone else with substantial influence over the organization) receives an economic benefit worth more than what they provided in return, the IRS treats the arrangement as an excess benefit transaction.11Internal Revenue Service. Intermediate Sanctions – Excess Benefit Transactions In the investment context, this most often shows up as management fees above fair market value paid to a firm connected to an insider.
The penalties are steep. The disqualified person owes a 25% excise tax on the excess benefit. If the transaction isn’t corrected within the taxable period, a second-tier tax of 200% applies. Any organization manager who knowingly participated owes a 10% tax on the excess benefit, capped at $20,000 per transaction.12Office of the Law Revision Counsel. 26 USC 4958 – Taxes on Excess Benefit Transactions
Every 501(c)(3) should adopt a written conflict-of-interest policy. The IRS asks about this directly on Form 990, including whether the organization has a disclosure process, how conflicts are managed, and how the board determines whether members have conflicting interests. At a minimum, the policy should require anyone with a potential conflict to disclose it and leave the room during discussion and voting on the matter. Many organizations also circulate an annual conflict questionnaire to board members and senior staff. Building that culture of candor upfront is far cheaper than defending an excess benefit transaction after the fact.
Reporting Investment Income to the IRS
Nonprofit investment income has to be reported annually, and the right form depends on the organization. Public charities with gross receipts of $200,000 or more (or total assets of $500,000 or more) file Form 990. Smaller public charities may file Form 990-EZ. Private foundations file Form 990-PF regardless of financial size.13Internal Revenue Service. Publication 4839 – Annual Form 990 Filing Requirements for Tax-Exempt Organizations
On Form 990, investment income appears in Part VIII, the Statement of Revenue. Dividends and interest go on Line 3, royalties on Line 5, rental income on Line 6, and gains or losses from selling securities and other investments on Lines 7a through 7d.14Internal Revenue Service. Instructions for Form 990 If the organization has $1,000 or more in gross unrelated business income, it also files Form 990-T.2Internal Revenue Service. Unrelated Business Income Tax Private foundations report their 1.39% excise tax on net investment income on Form 990-PF.7Internal Revenue Service. Tax on Net Investment Income
Failing to file these returns, even when no tax is owed, can trigger penalties. Three consecutive years of non-filing results in automatic revocation of tax-exempt status.
