As China grows richer, wealthy citizens, banks and private businesses have invested in Chinese art and started museums to display their wealth or patriotism. Others, such as Luo, opened their collections after their pastimes evolved into callings. In 1998, when he already owned about 70 old cars, Luo took part in an 800-kilometer (500-mile) rally from the northeastern city of Dalian to Beijing, his iconic Red Flag sedan the only Chinese car in the event.

Every serious collector eventually runs into the same uncomfortable question: what happens to the collection when I am gone? Heirs may not share their passion. Estate taxes can force a fire sale. The art, manuscripts, specimens, or artifacts you spent a lifetime assembling can end up scattered across auction houses within a year of your death.
There is an alternative worth considering. You can create a Private Operating Foundation (POF) to hold and preserve the collection as a private museum. Done properly, it keeps the collection intact, opens it to the public, and secures favorable tax treatment for both the collection and the collector, all while honoring the vision behind it.
What A Private Operating Foundation Actually Is
Most people picture a private foundation as an endowment that writes checks to charities. That is true of non-operating private foundations. A POF is a different animal. Much like a public charity, it does not simply fund other organizations: it actively conducts its own charitable, educational, or cultural work. The POF can own the collection, run the museum, acquire and conserve objects, mount exhibitions, and welcome the public.
That distinction matters because federal tax law treats a POF more like a public charity than an ordinary private foundation. POFs are exempt from the mandatory annual payout that other private foundations must make; and, donors enjoy more generous income-tax deduction limits. The structure suits people who want to do charitable work themselves rather than delegate it.
The Qualification Tests
To earn POF status under Section 4942(j)(3) of the tax code, an organization must clear two hurdles.
First is the income test: the foundation must spend substantially all (usually at least 85%) of its adjusted net income or its “minimum investment return” (which is calculated as 5% of the non-exempt use assets – such as the endowment- over the acquisition indebtedness) directly on the active conduct of its mission. For a museum, that spending is exactly what you’d expect: acquisition, conservation, and research of objects, climate control, security, storage, curatorial salaries, cataloging, exhibitions, and educational programming.
Second, the foundation must satisfy one of these three additional tests:
- The Asset Test, met if at least 65% of the foundation’s assets are devoted directly to the exempt purpose. The collection itself counts—so long as it is genuinely used for display, study, or research—as do the building that houses it, the conservation lab, the display cases, and the security systems.
- The Endowment Test, met if the foundation spent at least two-thirds of its minimum investment return directly on its mission. This is often the friendlier path for a collector whose endowment is large relative to the appraised value of the collection.
- The Support Test, met by drawing broad public support. In practice, private museums rarely rely on it.
A foundation is treated as “normally” meeting these tests, if it satisfies them in three of four consecutive years, or on an aggregate four-year basis. That gives useful breathing room when markets or exhibition schedules fluctuate.
The First Rule: Use It, Don’t Just Store It
If there is one principle a collector must internalize, it is this: their home, a warehouse or any other please where the public or researchers have little or no access is not a museum. The tax benefits flow from active conduct. A foundation can reasonably restrict access to objects that otherwise would be at risk if on display, but it can’t just lock its treasures in climate-controlled storage or worse, leave the objects on display in your living room. To do so risks losing its tax-exempt status altogether. A collection held behind closed doors starts to look, to the IRS, like an investment portfolio or personal property rather than a charitable enterprise.
The remedy is to build genuine public engagement into the foundation’s operations. That means regular public access through exhibitions, posted hours, or tours, along with educational programs, lectures, and publications, scholarly research access, and rigorous cataloging. Digital access can extend the reach further, and virtual tours, online exhibitions, and searchable databases can even substitute for physical access when handling fragile objects would put them at risk. The foundation can also loan objects, whether temporarily or on a long-term basis.
Governance Is Not Optional
A private museum lives or dies on its governance. Assemble a board that pairs subject-matter expertise—art history, archives, natural science—with the financial and legal knowledge needed to stay compliant. Adopt written acquisition and deaccessioning policies and take self-dealing seriously: transactions between the foundation and its founder or family are tightly restricted under Section 4941, and violations carry stiff excise taxes.
Recordkeeping is the unglamorous heart of compliance. Every dollar should be classified—direct exempt activity, investment-related, or administrative—and the allocation methodology documented and applied consistently year after year. Each year the foundation files Form 990-PF, certifies its operating status, and should conduct an internal review to confirm it remains on track across the four-year testing window.
Finally, everything should be as transparent as possible, with all actions by staff and trustees double checked to catch any problems before they become a crisis.
A Simple Illustration
Imagine a collector, Jane Doe, who contributes a trove of colonial-era manuscripts along with a $10 million endowment to a newly formed foundation. At year end, the manuscripts are appraised at $4 million and the climate-controlled facility—reading room, gallery, and conservation lab—at $1.5 million, for total assets of $15.5 million.
Because the collection and building fall below 65% of total assets, the foundation relies on the endowment test rather than the assets test. Its minimum investment return is roughly $500,000. That year the foundation spends $450,000 on conservators and curators, security and storage, digitization, public exhibitions, school programs, and a scholarly catalog. That figure sits comfortably above both the income test’s 85% threshold and the endowment test’s two-thirds mark. Investment-management fees are tracked separately and excluded. With sensible policies and an engaged board, the museum qualifies.
Conclusion
A private operating foundation is a stewardship structure with tax benefits. It asks the collector to trade private enjoyment for public benefit, and in return it offers a way to keep a collection whole, protected, and meaningful for generations. For the collector who cannot bear the thought of seeing a life’s work broken up and dispersed, that trade is often well worth making.
