Some university endowments are taxed. There are limits on how endowment funds can be spent

The numbers Kirk cited are in the ballpark. But his tweet oversells the liquidity and versatility of these endowments. They are not cash reserves that schools can draw on without restriction. The tweet also misleads about taxation — the largest of these endowments have been taxed by the federal government since a 2017 law went into effect, though the institutions themselves opposed it.

Some universities, including the ones Kirk listed, have endowments valued at several billion dollars.

In 2021, universities reported endowments valued at: 

• $53.2 billion for Harvard University;

• $42.3 billion for Yale University;

• $37.8 billion for Stanford University;

• and $37.7 billion for Princeton University. 

Kirk’s numbers appear to reflect reported values in 2020, when Yale’s endowment was about  $31.2 billion, Stanford’s was $28.9 billion and Princeton’s was $26.6 billion.

Andrew Kolvet, a Kirk spokesperson, said private equity tends to perform better than the stock market, so it’s possible Harvard’s endowment could now exceed $54 billion.

Harvard attributed significant endowment returns in 2021 to private and public equity markets. 

Hedge funds pool investors’ money and invest it in an effort to earn a positive return, according to the Securities and Exchange Commission.  

An endowment is a pool of donated funds meant to be invested to maximize returns, but its purpose is more specific: An endowment’s returns are meant to support education at the institution in perpetuity.

Each year, endowment investments accrue returns that are used one of two ways. Some are retained in the endowment so it will continue to grow and support the university in the future. Some are used to support the institution’s budget.

Universities use endowment distributions to support professorships, financial aid for undergraduates, academic programs, libraries, art museums and other facilities and activities. 

A percentage of an endowment’s annual payouts are subject to donor-imposed restrictions that require money to support specific programs, departments or purposes. These restrictions limit an institution's ability to access and spend endowment distributions.

Endowment funds are often invested in hedge funds to maximize returns, but they are not hedge funds themselves. The National Association of College and University Business Officers’ survey of 720 university endowments found that 17% of endowment funds are invested in hedge funds, on average.

Managers of larger nonprofit endowments typically invest in more private equity and venture capital, said Liz Clark, the association’s vice president for policy and research. 

Larger endowments also allocate more funds to marketable alternatives such as hedge funds, she said. The research shows that institutions with endowments over $1 billion are more likely to allocate a higher proportion of their investments to those marketable alternatives.

Vice President Kamala Harris' plan “will raise taxes for the typical American family by an estimated $3,000."

In 2021, Harvard reported that 33% of its assets were invested in hedge funds, for example. 

Still, a person who invests in a mutual fund is not a mutual fund. The same is true of endowments, said Sandy Baum, a senior fellow on education data and policy at the Urban Institute, a nonprofit research group.

Institutions want to maximize returns on their endowment, "but the purpose of the endowment is to fund the education of current and future students at the institution," Baum said.

Kirk’s assertion that these funds are not taxed is wrong. Since a 2017 change in law, some private colleges and universities have seen their endowments’ investment return income subjected to a 1.4% excise tax. 

The tax was part of a Republican-backed tax overhaul signed into law by President Donald Trump. Before that, university endowments were largely untaxed.

The excise tax applies to colleges with endowments larger than $500,000 per student. 

Experts said it is unclear exactly how many universities have been subject to this tax, but a 2018 Urban Institute report said the tax impacts 25 to 30 institutions that together "enroll fewer than 150,000" of the nation’s 20 million postsecondary students. In 2022, The Intercept reported that the tax affects over 40 private universities.

The Congressional Budget Office estimated the tax would raise $200 million annually, Bloomberg News reported. 

In 2019, Harvard University faced a $50 million total federal tax bill, with about $37.7 million of that amount stemming from the endowment tax. The university’s operating budget that year was about $5.4 billion.

Stanford University said it faced a tax bill of about $43 million for fiscal year 2019 because of the new tax. The school’s operating budget was $6.8 billion.

Federal tax revenue goes directly to the U.S. Treasury when collected; most federal spending comes from general Treasury funds, Clark said. 

Harvard and other wealthy private universities are lobbying for changes to or a repeal of the excise tax, The Intercept and Inside Higher Ed reported. The universities argue that endowments are crucial for funding financial aid programs, and any tax on endowment returns reduces their capacity to support low-income students.

Kirk tweeted, "Harvard is sitting on top of a $54 billion hedge fund they call an ‘Endowment’ that they pay zero taxes on. Yale has $31 Billion. Stanford $29 Billion. Princeton $26 Billion."

Kirk was in the ballpark about the size of these endowments, though his numbers might be slightly outdated; the most recent numbers show they’re even bigger. But calling such an endowment a "hedge fund" is a misnomer. Endowment funds are often partially invested in hedge funds to maximize returns, but they are not hedge funds themselves. His claim that these large endowments are entirely untaxed is wrong: Institutions like those he cited in the tweet have been paying a modest but real 1.4% excise tax on their investment returns since a 2017 change in tax law.
