Read this article if you are a manager, executive director, or CFO at a private foundation.
Private foundations play an essential role in the philanthropic landscape, supporting charitable causes and driving social impact. However, their activities are subject to significant oversight by tax authorities and must adhere to strict standards regarding how funds are invested and distributed. Among the most important areas of compliance for private foundations to understand are the calculation of Minimum Investment Return (MIR), understanding qualifying distributions, and recognizing the significance of direct charitable expenditures. Over the next few months, we will take a deep dive into each of these three core concepts. For this first article in our three-part series, we’ll explore the MIR.
As with all trilogies, the first chapter sets the stage for future installments. For illustrative purposes, we will be following the McQueen Family Foundation, a non-operating foundation, which must calculate its MIR as a first step in determining the number of distributions required for the year.
MIR: The foundation of distribution obligations
The MIR is a critical component for all private foundations—whether operating (i.e., conducting an exempt purpose function) or non-operating (i.e., an organization that primarily makes grants to other public charities in furtherance of their exempt purposes). MIR is used in part to determine how much the foundation must distribute annually to avoid penalties and maintain tax-exempt status. MIR is not a measure of profits or actual earnings, but rather is a standardized calculation based primarily on the value of the foundation’s investment (i.e., non-charitable use) assets.
The primary purpose of the MIR is to ensure private foundations put their endowments to charitable use rather than accumulating excessive wealth with little to no public benefit. By imposing a minimum distribution requirement, Congress and the IRS seek to prevent foundations from serving as perpetual savings vehicles and help to encourage timely and impactful giving.
Calculating the MIR
The MIR is generally calculated as 5% of the average fair market value of the foundation’s non-charitable-use assets over the preceding year. Below is a general overview:
- Identify non-charitable-use assets: These include investments such as stocks, bonds, real estate held for investment, and other assets not directly used in the foundation’s charitable programs. Assets used directly in conducting charitable activities (such as office space for grantmaking) are excluded from this calculation.
- Calculate the average value of cash and securities: Typically, foundations determine the fair market value of these assets monthly (beginning of month value + end of month value)/2. These balances (there should be 12 of them) are then added together and divided by 12 to arrive at an average annual value.
- Note: While many would consider cash to be exclusively for charitable use (it is generally what is used by foundations for grant-making purposes after all), the IRS only deems 1.5% of average cash balances to be held for charitable use. All other cash is considered fair game for the MIR calculation.
- Identify the fair market value of all other assets: In this step, the fair market value of any other assets not used for charitable purposes must be identified. This determination of value is done annually, and any date can be used as long as the same date is used every year. Special rules apply for real estate, which can be revalued every five years and must be appraised by a qualified appraiser.
- Reductions claimed for blockage and acquisition indebtedness: Blockage refers to a reduction in the fair market value of certain assets—typically securities—and reflects the reality that selling a large block of securities may depress the market price, especially if the securities are not widely traded. There is also an allowable reduction in arriving at MIR for any amount of acquisition indebtedness (debts used to acquire or improve the property) related to assets includible in the calculation.
- Apply the 5% rate: The IRS-mandated percentage (currently 5%) is applied to determine the minimum investment return.
Example:
The McQueen Family Foundation, working diligently with their CPA firm, has computed the value of all non-charitable-use assets for the year to be $10,700,000 based on the calculation in the chart below. After reducing this amount for cash deemed held for charitable use, the MIR for the year is calculated to be $526,975. This figure forms the basis for the McQueen Family Foundation’s distribution requirements for the year.

Implications and compliance
Accurate calculation of a foundation’s MIR is imperative. Failure to meet minimum distribution requirements can result in excise taxes and repeated/uncorrected distribution errors can potentially jeopardize the foundation’s tax-exempt status. Foundations often establish and document investment and grantmaking practices and policies to ensure distributions meet these required minimum thresholds.
The MIR serves as a vital mechanism to ensure private foundations fulfill their philanthropic missions and remain accountable to the public. By adhering to IRS guidelines and maintaining diligent records, foundations not only avoid costly penalties but also contribute meaningfully to the communities and causes they support. Ultimately, the minimum investment return is more than a regulatory hurdle—it is a catalyst for purposeful giving and sustained charitable impact.
