Quick Answer

Yes, a private foundation can pay its founders, family, officers, and board members — but only if the pay is reasonable and for personal services that are reasonable and necessary to the foundation’s exempt purpose. For tax year 2025, pay above that line is “self-dealing” under IRC Section 4941, triggering excise taxes.

What “Reasonable Compensation” Really Means Here

A private foundation is a tax-exempt charity, usually funded by one family, person, or company. The people closest to it — the donor, their family, and the officers — are called disqualified persons. Federal law treats most money flowing from the foundation to those insiders with deep suspicion, because the money was meant for charity, not for the people who run it.

Most insider deals are banned outright. But paying a disqualified person for real work is one of the few protected exceptions. The catch is that the pay must clear two separate tests, and missing either one converts a paycheck into a taxable act of self-dealing. According to the IRS data on tax-exempt organizations, there are well over 100,000 private foundations in the United States, and compensation is one of the most common areas the IRS examines.

The Two-Part Test Behind Every Legal Payment

Compensation to an insider is allowed under the Section 4941 exception only when two conditions both hold. First, the payment must be for personal services. Second, those services must be reasonable and necessary to carry out the foundation’s exempt purpose, and the amount must not be excessive.

If either part fails, the entire payment — not just the excess — can be treated as self-dealing. That is the trap most people miss.

Part One: It Must Be For “Personal Services”

The exception only covers personal services, which the IRS reads narrowly. It clearly includes legal work, accounting, investment management, and general administration of the foundation. It does not cover most other dealings, such as a foundation buying goods or property from an insider, even at a fair price.

The consequence of crossing this line is severe: if the payment is not for a covered personal service, no exception applies and the whole payment is self-dealing. For example, paying a founder’s company for office furniture is not a “personal service” and is taxable, even if the price is a bargain. A common misconception is that “any fair-value deal is fine” — it is not; the type of service matters as much as the price. Before paying an insider, confirm in writing that the work is a personal service, and document the business need.

Part Two: The Amount Must Be Reasonable and Necessary

The second part has two pieces. The service must be necessary to the foundation’s charitable mission, and the pay must be reasonable — meaning not more than what a similar organization would pay for similar work, as described in the IRS guidance on the meaning of “reasonable” compensation.

The consequence of overpaying is a self-dealing excise tax on the full amount paid, not just the overage. Picture a foundation paying a founder’s daughter $120,000 to answer email a few hours a week — that fails both “necessary” and “reasonable.” The frequent misconception is that compensation is judged like the public-charity rule, where only the excess is taxed; under the private-foundation self-dealing rule, the entire payment can be tainted. To stay safe, benchmark every salary against real market data and keep the proof.

How “Reasonable” Is Measured

There is no magic number. The IRS looks at total compensation — salary, bonuses, deferred pay, and benefits — against what comparable employers pay for comparable jobs. Useful comparisons come from compensation surveys, Form 990 and 990-PF filings of similar foundations, and salary studies for the role, region, and organization size.

Key factors include the person’s duties and hours, their qualifications and experience, the size and complexity of the foundation, the local market, and what similar nonprofits pay. A part-time role cannot command a full-time salary, and a tiny foundation cannot justify big-foundation pay. The burden is on the foundation to show the pay was reasonable when it was set, so the documentation must exist up front, not be invented during an audit.

The Excise Taxes: What Self-Dealing Actually Costs

When compensation crosses the line, Section 4941 imposes excise taxes in two tiers, and they fall on people, not the foundation itself.

The first-tier tax is 10% of the amount involved, charged to the disqualified person who received the self-dealing payment, for each year (or part of a year) in the taxable period. A separate 5% first-tier tax, capped at $20,000 per act, hits any foundation manager who knowingly approved it, unless their action was not willful and was due to reasonable cause.

If the transaction is not corrected in time, a second tier applies: 200% of the amount involved on the disqualified person, and 50% (capped at $20,000) on a manager who refuses to fix it. “Correction” generally means undoing the deal and making the foundation whole, with interest. These taxes are reported and paid on Form 4720.

Section 4941 vs. Section 4958 — Don’t Mix Them Up

People often confuse two different regimes. Private foundations live under the Section 4941 self-dealing rules. Public charities and similar groups live under the Section 4958 intermediate sanctions, where only the excess benefit is taxed at 25% (then 200% if not corrected), plus a 10% manager tax capped at $20,000.

The practical difference is huge. Under Section 4958, overpaying a public-charity executive taxes only the overage; under Section 4941, a payment that fails the personal-services exception can be self-dealing on the entire amount. Confusing the two leads foundations to under-react to a much harsher rule. If you run a private foundation, apply Section 4941 — full stop.

Compensation Rule Feature	How It Works
Governing law for private foundations	Section 4941 self-dealing rules
Governing law for public charities	Section 4958 intermediate sanctions
What gets taxed when pay fails	Foundation: potentially the full payment; public charity: only the excess benefit
First-tier tax on recipient	Foundation: 10% of amount involved; public charity: 25% of excess
Second-tier tax if not corrected	Foundation: 200%; public charity: 200%
Where it is reported	Form 4720 and Form 990-PF

The Rebuttable Presumption: Your Best Shield

Foundations can build strong protection by following the comparability process drawn from the Section 4958 regulations. Many private-foundation boards use it as best practice even though it is technically a 4958 tool, because it documents reasonableness the same way.

Three steps create a rebuttable presumption that pay is reasonable. First, the compensation is approved in advance by an authorized body of the foundation. Second, that body relies on appropriate comparability data before deciding. Third, the body documents the basis for its decision at the time, in the meeting minutes.

The benefit is that the burden then shifts to the IRS to prove the pay was unreasonable. Without this record, the foundation carries the burden — a far weaker position in an audit. The step boards skip most often is the contemporaneous write-up; minutes drafted months later do not count.

What Counts as Comparability Data

Acceptable data includes salaries paid by similar organizations for similar roles, independent compensation surveys by recognized firms, and actual written offers for the position. For small foundations with gross receipts under a set threshold, the rules allow a simpler version using data from a limited number of comparable organizations in the same area.

The consequence of weak data is a presumption that never forms, leaving the foundation exposed. A board that “just knows” market pay has no defense. Gather at least three solid comparables, attach them to the minutes, and refresh them when duties or pay change.

Reimbursing Expenses Without Triggering Self-Dealing

Paying back a disqualified person’s reasonable and necessary expenses for foundation work is allowed under the same compensation exception. This covers things like travel to grantee site visits or board meetings, as long as the spending is ordinary and documented.

The line is lavish or unnecessary spending, which is not protected and becomes self-dealing. First-class luxury travel a tiny foundation cannot justify is the classic problem. Keep receipts, adopt a written reimbursement policy, and treat foundation spending as charitable money, because that is what it is.

Which Situation Applies to You?

The rules bend depending on who you are and what the foundation is paying for. Use this to find your path.

• You are the founder taking a salary: You are a disqualified person; your pay must pass both parts of the test and be benchmarked and board-approved.
• You want to pay your spouse or child: Family members are disqualified persons too; the same tests apply, and “necessary” is scrutinized harder for relatives.
• You are a board member who is also a paid advisor: Investment and legal services are covered personal services, but the advisor should not vote on their own pay.
• You are a foundation manager approving pay: You face your own 5% (then 50%) manager tax if you knowingly approve unreasonable pay.
• You are reimbursing travel or supplies: Allowed if reasonable and documented; lavish costs are self-dealing.

Worked Examples With Real Numbers

Example 1 — Founder’s Salary (Reasonable)

Maria founds a $10 million family foundation and works full-time as its executive director, managing grants and operations. The board gathers three comparable surveys showing similar EDs at similar foundations earn $90,000 to $130,000. The board approves $110,000 and records the data in its minutes.

Here is the math: $110,000 sits inside the documented market range, the role is necessary, and the process built a rebuttable presumption. The result is $0 in excise tax and a clean audit position. The total compensation tested includes salary plus benefits, so if Maria also gets $15,000 in health benefits, the board benchmarks the full $125,000.

Example 2 — Overpaying a Relative (Self-Dealing)

David’s foundation pays his son $80,000 to manage social media a few hours a month, with no comparables and no board vote. Comparable part-time roles pay roughly $12,000.

The IRS treats the payment as failing the reasonable-and-necessary test. Under Section 4941, the amount involved can be the excessive portion, $68,000 ($80,000 minus the $12,000 reasonable value). The first-tier tax is 10% of $68,000 = $6,800 on the son for each year in the taxable period. If David, as manager, knowingly approved it, he owes 5% = $3,400 (within the $20,000 cap). If not corrected, the son faces 200% = $136,000.

Example 3 — Board Member Investment Advisor (Reasonable)

Priya sits on the board and runs an investment firm. Her firm manages the foundation’s $25 million portfolio for a 0.50% fee, or $125,000 a year. The board obtains quotes from three independent managers ranging from 0.45% to 0.65%, approves the deal with Priya recused, and documents it.

The math works: investment management is a covered personal service, the 0.50% fee is mid-market, and the process is clean. Result: $0 excise tax. Had Priya voted on her own fee, she would risk being treated as a self-dealing manager even at a fair price.

Three Common Scenarios

Compensation Setup	Tax Outcome
Founder paid market-rate salary, board-approved with three comparables documented in minutes	No self-dealing; rebuttable presumption protects the foundation
Spouse paid far above market with no benchmarking or vote	Self-dealing; 10% first-tier tax now, 200% if not corrected; manager tax possible
Insider’s company paid fair price to sell the foundation office equipment	Self-dealing on the full amount; sale of property is not a covered personal service

Step-by-Step: Setting Defensible Compensation

Follow this process before any insider is paid.

1. Confirm the work is a personal service (legal, accounting, investment, or administration) and write down why it is necessary.
2. Gather at least three pieces of comparability data for the role, region, and foundation size.
3. Have an authorized board body approve the pay in advance, with conflicted members recused.
4. Record the decision and the data in contemporaneous minutes the same day.
5. Report the compensation on Form 990-PF, Part VII, which is public, and keep all backup.

Deadlines, Costs, and Timing

Form 990-PF is due the 15th day of the 5th month after the foundation’s tax year ends — May 15 for a calendar-year foundation — with a six-month extension available on Form 8868. If self-dealing occurs, Form 4720 is generally due with that same filing.

Correction must happen within the taxable period to avoid the 200% second-tier tax, so speed matters once a problem is spotted. Costs vary: a DIY benchmarking effort using free 990-PF data costs only time, while a formal compensation study from a consulting firm typically runs from a few thousand dollars upward. A nonprofit tax attorney or CPA to fix a self-dealing problem can cost more, but far less than an uncorrected 200% tax.

Mistakes to Avoid

• Paying for non-personal services. Buying property or goods from an insider is self-dealing even at fair value; the whole payment is taxed.
• Skipping comparability data. Without it, no rebuttable presumption forms and the foundation bears the burden in an audit.
• Writing minutes late. Documentation must be contemporaneous; after-the-fact minutes do not protect you.
• Letting an insider approve their own pay. A recipient who votes on their own compensation risks self-dealing treatment regardless of amount.
• Ignoring benefits in the total. Reasonableness is judged on salary plus bonuses, deferred pay, and benefits, not base salary alone.
• Overpaying a relative for light work. “Necessary” is scrutinized hardest for family; thin duties plus a big check invites tax.
• Reimbursing lavish expenses. Luxury travel or unnecessary costs fall outside the exception and become self-dealing.

Do’s and Don’ts

Do: – Benchmark every insider’s pay against real market data, because the foundation must prove reasonableness. – Approve compensation in advance through the board, because timing is part of the legal shield. – Recuse anyone with a conflict, because self-interested votes undermine the deal. – Keep receipts and a written expense policy, because reimbursements must be documented. – Reassess pay yearly, because reasonableness is tested when each payment is set.

Don’t: – Don’t pay insiders for selling goods or property, because that is not a covered personal service. – Don’t treat fair price as automatically safe, because the type of transaction matters too. – Don’t assume only the excess is taxed, because Section 4941 can tax the full payment. – Don’t rely on memory for market rates, because undocumented “knowledge” is no defense. – Don’t delay correction, because the 200% second-tier tax follows uncorrected self-dealing.

Pros and Cons of Paying Insiders

Pros: – Compensates founders and family for genuine work, which keeps talented people engaged. – Lets the foundation hire trusted experts who already understand its mission. – Investment and legal services from insiders can be cost-effective when fairly priced. – A clean compensation process builds a strong, audit-ready record. – Reasonable pay is fully legal and common, so insiders need not work for free.

Cons: – Every insider payment is scrutinized as potential self-dealing, raising compliance work. – A mistake can tax the entire payment, not just the excess. – Manager-level taxes can hit board members personally. – Compensation appears publicly on Form 990-PF, inviting outside criticism. – Building comparability data and minutes takes ongoing time and sometimes money.

What to Do Next

1. List every payment your foundation makes to insiders this year, including salaries, fees, and reimbursements.
2. For each, confirm it is a covered personal service that is necessary to the mission.
3. Pull three comparables and have the board approve or re-approve the pay in advance, with conflicts recused.
4. Write contemporaneous minutes capturing the data and decision, and file them with your records.
5. Report everything accurately on Form 990-PF, and call a nonprofit tax attorney or CPA before paying any insider when the role, the relationship, or the dollar amount is unusual or large.

FAQs

Can a private foundation pay its founder a salary? Yes. A founder can be paid for personal services that are reasonable and necessary to the foundation’s exempt purpose. The pay must be benchmarked to market and approved by the board to avoid self-dealing under Section 4941.

Can a private foundation pay family members? Yes, but family are disqualified persons, so the same reasonable-and-necessary test applies. The IRS scrutinizes whether the relative’s work is truly necessary, and overpaying triggers self-dealing excise taxes for tax year 2025.

What is the excise tax on self-dealing compensation? 10% of the amount involved is the first-tier tax on the recipient for 2025, plus a 5% manager tax capped at $20,000. If uncorrected, a 200% second-tier tax applies to the recipient.

Does the foundation itself pay the self-dealing tax? No. Section 4941 taxes the disqualified person who received the benefit and, in some cases, the foundation managers who approved it — not the foundation entity itself.

What counts as a “personal service”? Legal, accounting, investment management, and administrative services are the main covered categories. Selling goods, property, or facilities to the foundation does not qualify, even at a fair price.

How is reasonable compensation measured? By comparison to similar organizations paying for similar work. The IRS weighs duties, hours, qualifications, foundation size, and local market data, judged at the time the pay is set.

What is the rebuttable presumption of reasonableness? A safe-harbor process where the board approves pay in advance, uses comparability data, and documents the decision contemporaneously. Doing all three shifts the burden of proof to the IRS.

Can a board member be paid for investment advice? Yes. Investment management is a covered personal service, so a fair, documented fee is allowed. The board member should recuse from voting on their own compensation.

Where is compensation reported? On Form 990-PF, Part VII for officers, directors, and key employees. This form is public, and self-dealing taxes are reported on Form 4720.

Do states follow these federal rules? Mostly yes, but states add oversight. State attorneys general regulate charity insider dealings, and some states require separate registration or reporting, so check your state’s charity regulator in addition to the IRS.

What happens if I don’t correct self-dealing? A 200% second-tier tax is imposed on the recipient, plus up to 50% on a refusing manager (capped at $20,000). Correction means undoing the deal and making the foundation whole.

Can a small foundation use simpler comparability data? Yes. Foundations under the set gross-receipts threshold may rely on data from a limited number of comparable organizations in the same geographic area, easing the documentation burden.
