Section 4958 of the Internal Revenue Code: Excise Tax and Correction

Section 4958 of the Internal Revenue Code imposes an excise tax on insiders of certain tax-exempt organizations who receive more than fair market value in a transaction with the organization. The tax falls on the individual who got the excess benefit, not on the organization itself, and it comes in two tiers: 25% of the excess benefit up front, and 200% more if the problem isn’t corrected in time. A separate 10% tax hits managers who knowingly approved the deal. These rules are often called “intermediate sanctions” because they give the IRS a middle option between doing nothing and revoking tax-exempt status.¹

Section 4958 applies to public charities under 501(c)(3), social welfare organizations under 501(c)(4), and qualified nonprofit health insurance issuers under 501(c)(29).² Private foundations are governed by a different and stricter self-dealing regime, so if you’re dealing with a private foundation, Section 4958 isn’t your statute.

What Triggers the Tax

The tax is triggered by an “excess benefit transaction,” which is any economic benefit an exempt organization provides to an insider that exceeds the fair market value of what the organization gets back.¹ The excess benefit is the amount of the overpayment, and the excise tax is calculated on that amount. The whole transaction does not need to be unreasonable. Even a modest overpayment produces an excess benefit, and the tax applies to that slice.

Excessive compensation is the most common trigger. Compensation here is the full package: salary, bonuses, deferred pay, fringe benefits, and expense allowances, measured against the fair value of the services the person actually performs. If an executive director is paid $400,000 and solid comparable data supports only $250,000, the excess benefit is $150,000.

Property deals are the next common category. Selling, leasing, or exchanging property between the organization and an insider at an off-market price creates an excess benefit equal to the difference. Loans draw similar scrutiny. A loan without proper documentation, a market-rate interest charge, and a realistic repayment schedule can be recharacterized as an excess benefit equal to the outstanding balance.

Who Counts as a Disqualified Person

The 25% tax only applies to a “disqualified person,” defined as anyone who was in a position to exercise substantial influence over the organization’s affairs at any time during the five-year period ending on the date of the transaction.³ The five-year lookback matters: someone who rotated off the board three years ago can still be a disqualified person for today’s transaction.

Some roles carry automatic status. Officers, directors, and trustees are always disqualified persons as to the organizations they serve. Presidents, CEOs, COOs, treasurers, and CFOs are in by virtue of their titles. Highly compensated employees whose pay turns on revenue from activities they control are also treated as having substantial influence.⁴ Founders have no automatic designation, but the IRS treats a founding role as a strong factor pointing toward substantial influence.

Status extends to a disqualified person’s spouse, ancestors, children, grandchildren, great-grandchildren, and the spouses of those descendants. Siblings are not included. Entities that disqualified persons and their family members collectively control by more than 35% (voting power in a corporation, profits interest in a partnership, beneficial interest in a trust) are also disqualified persons, and transactions with them are treated like direct deals with the insider.³

How the Tax Is Calculated

The structure has two tiers, and the gap between them is enormous. The design is meant to push quick correction.

First Tier: 25% on the Disqualified Person

The disqualified person who got the excess benefit owes 25% of the excess benefit amount.⁵ On a $150,000 excess benefit, that’s $37,500. Intent doesn’t matter at this stage. An innocent overpayment still triggers the tax once the IRS determines the benefit exceeded fair value.

10% on Organization Managers

Managers who knowingly approved the transaction face a tax of 10% of the excess benefit.⁵ “Organization manager” covers officers, directors, trustees, and anyone with similar authority. The word doing the work is “knowingly”: a manager is liable only if they knew the transaction was an excess benefit transaction and their participation was willful and not due to reasonable cause. Each manager’s liability is capped at $20,000 per excess benefit transaction. If three board members knowingly approved a transaction with a $500,000 excess benefit, the 10% tax would be $50,000 in total, but no single manager would owe more than $20,000.

Second Tier: 200% for Failing to Correct

If the disqualified person does not correct the excess benefit within the taxable period, a second-tier tax of 200% of the excess benefit applies.⁵ Combined with the first-tier 25%, the total tax reaches 225% of the excess benefit. On a $150,000 excess benefit, that’s $337,500 in tax, on top of giving the money back.

The taxable period runs from the date of the transaction until the earlier of the date the IRS mails a notice of deficiency for the first-tier tax, or the date the first-tier tax is assessed.⁶ Once that window closes without correction, the 200% tax is on the table. This is where most of the financial damage comes from, and it is entirely avoidable with a prompt fix.

The organization itself owes no excise tax under Section 4958. A pattern of uncorrected excess benefit transactions can, however, lead the IRS to revoke the organization’s exempt status under other provisions.¹

Correcting an Excess Benefit Transaction

Correction means putting the organization in a financial position no worse than it would have been if the excess benefit had never happened. The standard route is to repay the full excess benefit, with a reasonable rate of interest running from the transaction date to the repayment date. If the organization incurred extra costs because of the transaction, such as legal fees or penalties, the correction may need to cover those as well.

When the benefit involved property instead of cash, the disqualified person may return that specific property with the organization’s agreement. The returned property is valued at the lesser of its fair market value on the date of return or its fair market value on the date of the original transaction.⁷ If the property’s value has dropped and the return doesn’t fully cover the correction amount, the disqualified person pays the shortfall in cash. If the value exceeds the correction amount, the organization may refund the difference.

The disqualified person reports the excess benefit transaction and the first-tier tax on IRS Form 4720.⁸ Each taxpayer who owes a Chapter 42 excise tax must file a separate Form 4720; the individual can no longer report the tax on the organization’s return.² Both sides should document the correction in their financial records.

How to Prevent the Tax: The Rebuttable Presumption

The strongest defense is to establish the rebuttable presumption of reasonableness before the transaction closes. When the organization follows the required process, the IRS has to prove the transaction was unreasonable, rather than the organization proving it was fair. That shift in burden matters a great deal during an audit.

Three steps are required.⁹

Independent Approval

The compensation arrangement or property transaction must be approved in advance by an authorized body, typically the board of directors or a compensation committee. Every member of that body must be free of conflicts of interest regarding the transaction. A member has a conflict if they are the disqualified person, are related to the disqualified person, or are subject to the disqualified person’s control. If even one conflicted member participates in the vote, the presumption fails.

Comparability Data

Before approving the terms, the authorized body must obtain and rely on appropriate comparability data. For compensation, that means things like surveys for similar positions at similarly sized organizations, documented offers from competing employers, or independent consultant analyses. For property, an independent appraisal is the standard form. A number that “feels right” is not enough. The data has to be on the table and demonstrably relied upon.

Concurrent Documentation

The authorized body must document its decision at or near the time of the decision. The regulations define “concurrently” as by the later of the next meeting of the body or 60 days after the final action is taken.¹⁰ The record must include the terms, the date, who was present, the comparability data reviewed, and any actions taken by members who had a conflict.

Miss any of these steps and the presumption is gone. The IRS then only needs to show the compensation or payment exceeded fair market value, with no burden-shifting in the organization’s favor.

Abatement of the First-Tier Tax

Under IRC Section 4962, the IRS has authority to abate, credit, or refund the first-tier 25% tax if two conditions are met: the taxable event was due to reasonable cause and not willful neglect, and the excess benefit was corrected within the correction period.¹¹ If the tax is abated, any associated interest is abated with it.

Reasonable cause requires the taxpayer to show they exercised ordinary business care and prudence. Not knowing the law isn’t enough. A board that hired an independent compensation consultant, reviewed comparability data, and made a good-faith decision that landed slightly above market has a plausible reasonable-cause argument. A board that rubber-stamped a package without any analysis does not. Abatement is discretionary, not automatic. Correction is a necessary condition, but on its own it does not get the first-tier tax removed.
