A foundation account is a dedicated bank account held by a nonprofit foundation to keep its charitable assets separate from any individual’s personal or business finances. The account belongs to the foundation itself as a legal entity, not to the donors, board members, or officers who manage it. Setting one up means more than walking into a bank: the foundation must exist as a corporation or trust, have an Employer Identification Number, and ideally hold a federal tax-exemption determination before the first dollar goes in. And once the account is open, federal rules dictate how much the foundation must give away each year, who it cannot do business with, how it can invest, and what it must report. Penalties for getting this wrong can reach 200% of the amount involved, so the rules deserve attention before the account exists, not after.
What the Account Actually Is
The foundation holds legal title to everything in the account. That separation is the point. Charitable money stays walled off from anyone’s personal finances regardless of who contributed it or who signs the checks.
Most foundations qualify for federal tax exemption under Section 501(c)(3), which covers organizations operated exclusively for charitable, educational, religious, scientific, or similar purposes.1Office of the Law Revision Counsel. 26 USC 501 – Exemption From Tax on Corporations, Certain Trusts, Etc. Within that umbrella, the IRS draws a line that shapes every rule the foundation lives under. A private foundation gets most of its funding from a single source, often one family or one company. A public charity draws broad public support. Private foundations face mandatory annual payouts, excise taxes on investment income, and strict self-dealing rules; public charities do not. If you are opening a foundation account, you almost certainly need to know which category you are in before you walk into the bank.
Get Tax-Exempt Status First
An EIN alone does not make a foundation tax-exempt. Any organization formed after October 9, 1969, must formally notify the IRS that it is seeking 501(c)(3) status, or it simply is not treated as exempt.2Office of the Law Revision Counsel. 26 USC 508 – Special Rules With Respect to Section 501(c)(3) Organizations
The standard application is Form 1023, which asks for a detailed account of the foundation’s activities, governance, and finances. The user fee is $600 for the full Form 1023.3Internal Revenue Service. Frequently Asked Questions About Form 1023 Filing within 27 months of formation allows the exemption to apply retroactively to the date the entity was legally created. Miss that window, and the exemption only kicks in on the date the IRS receives the application.
One default catches many new organizations by surprise: the IRS presumes every 501(c)(3) is a private foundation unless it affirmatively demonstrates otherwise during the application.2Office of the Law Revision Counsel. 26 USC 508 – Special Rules With Respect to Section 501(c)(3) Organizations If you qualify as a public charity, you have to prove it. Otherwise the full private foundation rulebook applies to you by default.
What the Bank Will Ask For
Once the foundation exists as a legal entity and has applied for (or received) its tax-exempt determination, a bank will want several documents before opening anything.
Start with the EIN, obtained by filing Form SS-4 with the IRS.4Internal Revenue Service. About Form SS-4, Application for Employer Identification Number The number functions as the foundation’s taxpayer ID for banking and tax purposes, and the online application usually returns it immediately.
Beyond the EIN, banks will ask for:
- The articles of incorporation, or the trust instrument if the foundation is organized as a trust.
- The bylaws, which spell out how internal decisions get made.
- A board resolution authorizing the account. The resolution should name each person who will have signing authority and describe what they can do: write checks, transfer funds, approve withdrawals, and so on. Banks rely on this document to know who can legally move the foundation’s money.
- Government-issued photo identification for each authorized signer.
One requirement that likely does not apply: beneficial ownership reporting under the Corporate Transparency Act. Organizations tax-exempt under Section 501(c) are exempt from filing beneficial ownership information with FinCEN, and the exemption also extends to organizations that lost exempt status within the past 180 days.5FinCEN.gov. Frequently Asked Questions
Opening and Verification
With the paperwork in hand, authorized signers submit the package to the bank, complete internal signature cards, and present identification. Banks are required by law to run a customer identification program, often called Know Your Customer, that verifies the name, address, and identity of anyone associated with the account.6Office of the Comptroller of the Currency (OCC). What Type(s) of ID Do I Need to Open a Bank Account? The bank then vets the organization and screens the individuals. This usually takes a few business days; more complex structures take longer. Most banks also require a minimum opening deposit, which varies by institution.
The 5% Annual Payout Rule
A private foundation cannot stockpile money. Section 4942 requires each private foundation to distribute a minimum amount every year: 5% of the fair market value of its non-charitable-use investment assets, measured as a monthly average over the tax year.7Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income Assets the foundation uses directly in its charitable work, such as program buildings or equipment, are excluded from the base.
Qualifying distributions include grants to other nonprofits, direct charitable expenditures, and reasonable administrative costs tied to exempt activities. Staff salaries, travel, and operating costs count if they are reasonable and connected to the exempt mission.8Internal Revenue Service. Directly for the Conduct of Exempt Activities Costs tied to producing investment income, like portfolio-manager fees, do not.
Miss the minimum and the penalties escalate quickly. If a foundation fails to meet its required distribution by the start of the second year after the shortfall, the IRS imposes a 30% tax on the undistributed amount. If the shortfall is still not corrected by the end of the correction period, a 100% tax applies to whatever remains undistributed.7Office of the Law Revision Counsel. 26 USC 4942 – Taxes on Failure to Distribute Income In practice, the IRS will eventually take the entire amount the foundation should have given away.
Self-Dealing and Disqualified Persons
This is where foundations get into trouble most often. Federal law prohibits nearly all financial transactions between a private foundation and its “disqualified persons,” a category that includes substantial contributors, foundation managers, their family members, and entities those people control.9Internal Revenue Service. Acts of Self-Dealing by Private Foundation
Prohibited transactions include:
- Sales or leases between the foundation and a disqualified person, in either direction.
- Loans or extensions of credit, in either direction.
- Compensation to a disqualified person, unless it is reasonable payment for personal services necessary to carry out the foundation’s exempt purpose.
- Transfers of foundation income or assets to or for the benefit of a disqualified person, directly or indirectly.
The penalties hit both sides. A disqualified person who participates in self-dealing owes an initial tax of 10% of the amount involved for each year the transaction remains uncorrected. A foundation manager who knowingly participates owes 5%. If the deal is not unwound within the correction period, the tax on the disqualified person jumps to 200%, and a manager who refused to agree to correction owes 50%.10Office of the Law Revision Counsel. 26 USC 4941 – Taxes on Self-Dealing These numbers dwarf any benefit the transaction might have produced.
Investment Restrictions
Section 4944 taxes any investment that jeopardizes the foundation’s ability to carry out its charitable purpose. The test is whether managers exercised ordinary business care and prudence given the foundation’s short- and long-term financial needs.11eCFR. Subpart E – Taxes on Investments Which Jeopardize Charitable Purpose
No category of investment is automatically off-limits, but several draw close scrutiny: margin trading, commodity futures, short selling, and speculative options strategies like puts and straddles. Investments in highly speculative start-ups or undercapitalized ventures with little prospect of current return raise the same questions. The analysis always looks at the risk in light of the whole portfolio and the mission.
If an investment is found to be jeopardizing, the foundation owes 5% of the amount invested for each year it remains in jeopardy, and any manager who participated knowing it was imprudent owes another 5%. Failure to remove the investment during the correction period triggers a 25% tax on the foundation and a 5% tax on any manager who refused to correct.11eCFR. Subpart E – Taxes on Investments Which Jeopardize Charitable Purpose
Rules for Grants Out of the Account
How money leaves the account matters as much as how much leaves. When a private foundation makes grants directly to individuals, such as scholarships or fellowships, it has to follow procedures the IRS approves in advance. The foundation must show that its selection process is objective and nondiscriminatory, that it is designed to ensure recipients use the money for its stated purpose, and that the foundation will follow up to confirm compliance.12Internal Revenue Service. Advance Approval of Grant-Making Procedures Once approved, the procedures carry forward to future programs unless the foundation materially changes its approach.
When a private foundation grants to an organization that is not itself a public charity, it must exercise “expenditure responsibility.” That means taking reasonable steps to ensure the grant is spent only for its stated purpose, collecting detailed reports from the grantee on how the funds were used, and filing a separate report with the IRS.13Internal Revenue Service. Grants by Private Foundations – Expenditure Responsibility A pre-grant inquiry into the grantee and a written agreement requiring return of any unspent funds are standard parts of the process. Skip these steps and the grant can be treated as a taxable expenditure.
Annual Filings and Taxes
Every private foundation files Form 990-PF each year, reporting total assets, investment income, grants, and expenses.14Internal Revenue Service. 2025 Instructions for Form 990-PF Public charities file Form 990 or 990-EZ instead. These returns are public documents, so accuracy affects reputation as well as legal standing.
Private foundations also owe a 1.39% excise tax on net investment income each year, calculated on interest, dividends, and capital gains.15Office of the Law Revision Counsel. 26 USC 4940 – Excise Tax Based on Investment Income The tax applies no matter how much the foundation distributes, and is paid in quarterly estimated installments.16Internal Revenue Service. Publication 509 (2026), Tax Calendars
Unrelated Business Income
If a foundation earns money from a regularly conducted business activity that is not substantially related to its charitable purpose, that income is taxable. A foundation files Form 990-T if its gross unrelated business income reaches $1,000 or more in a year.17Internal Revenue Service. Instructions for Form 990-T Passive investment income (dividends, interest, royalties, and most rental income) is excluded.18Internal Revenue Service. Unrelated Business Income Tax Exceptions and Exclusions
What Happens If Returns Are Missed
Any tax-exempt organization that fails to file its required annual return for three consecutive years automatically loses its tax-exempt status. The revocation happens by operation of law, not by an IRS decision, and takes effect on the filing due date of the third missed return.19Internal Revenue Service. Automatic Revocation of Exemption Getting back in requires a new application and another user fee. For a foundation holding real assets, revocation means investment income becomes fully taxable and donor contributions stop being deductible. Monthly reconciliation and clean records throughout the year make the annual filing far less painful than reconstructing twelve months of transactions the week before the deadline.
