Private equity investing has traditionally been associated with institutions and ultra-high-net-worth investors. However, it has also played a significant role inside retirement accounts. One of the most well-known examples is former Massachusetts governor and presidential candidate Mitt Romney, who reportedly grew his IRA to more than $100 million by investing in private equity deals through Bain Capital.
So why would someone choose to invest in private equity using a Self-Directed IRA?
The answer comes down to taxes.
When private equity investments are held inside a Self-Directed IRA, gains can grow tax-deferred in a traditional IRA or potentially tax-free in a Roth IRA. This allows profits to compound without being reduced by annual capital gains or income taxes, which can dramatically impact long-term returns.
Below is what investors need to know about investing in private equity with a Self-Directed IRA and how to do it correctly.
What Is Private Equity?
Private equity is a broad term used to describe investment funds that pool capital from multiple investors, typically through a passthrough entity such as a partnership or LLC, to acquire ownership stakes in private companies. These investments may include:
- Mature businesses in need of restructuring or operational improvements
- Growth-stage companies seeking expansion capital
- Distressed companies requiring a turnaround
Private equity is often confused with venture capital. While similar, there is a key distinction. Private equity generally targets more established, revenue-generating businesses, whereas venture capital focuses on early-stage companies that may have little or no revenue.
Both private equity and venture capital funds raise money from accredited investors, family offices, pension funds, institutions, and increasingly, Self-Directed IRAs.
Private equity funds typically earn revenue through:
- A management fee, often around 2 percent annually
- A carried interest, usually 20 percent of profits above a minimum return threshold
Although fees are higher than traditional investments like mutual funds or ETFs, investors participate with the expectation that returns will justify the cost.

How a Self-Directed IRA Invests in Private Equity
A Self-Directed IRA allows you to use pre-tax, Roth, SEP, or SIMPLE IRA funds to invest in private equity and venture capital opportunities. There are two primary structures available.
1. Custodian-Controlled Self-Directed IRA
With a custodian-controlled SDIRA:
- A specialized IRA custodian holds your IRA assets
- At your direction, the custodian executes the investment into the private equity fund
- The investment is titled in the name of the IRA
This structure works well for passive private equity investments that involve relatively few transactions, such as an initial capital contribution followed by occasional capital calls.
2. Self-Directed IRA LLC (Checkbook Control)
The Checkbook Control structure uses a specially formed LLC that is:
- 100 percent owned by the IRA
- Managed by you (without compensation) or a third party
- Equipped with its own dedicated bank account
With this structure, you can fund private equity investments by writing a check or sending a wire directly from the IRA LLC bank account. This approach is ideal when timing matters, capital calls must be met quickly, or multiple private investments are involved.
For lower-frequency private equity investments, a custodian-controlled SDIRA is often sufficient. Investors seeking speed, flexibility, and reduced transaction friction frequently prefer the Checkbook Control model.
Understanding the Prohibited Transaction Rules
When investing in private equity with a Self-Directed IRA, compliance with IRS prohibited transaction rules under Internal Revenue Code Section 4975 is critical.
A “disqualified person” includes:
- The IRA owner
- A spouse
- Parents, grandparents, children, and grandchildren
- Entities controlled by the IRA owner or other disqualified persons
Your IRA cannot invest in a private equity fund if you or another disqualified person has:
- An ownership interest
- A management, employment, or compensated role
- Any arrangement that provides a direct or indirect personal benefit
In simple terms, your IRA may invest in almost any private equity fund as long as neither you nor your family members are personally involved in the fund.
In some cases, it may be possible to invest in a fund where you have a professional relationship, but these situations require careful analysis to ensure there is no direct or indirect personal benefit. Prohibited transaction determinations are highly fact-specific, and mistakes can result in severe taxes and penalties.
Understanding UBTI in Private Equity Investing
Most private equity investments held in a Self-Directed IRA do not generate Unrelated Business Taxable Income (UBTI). However, UBTI can apply under certain circumstances, including when:
- The private equity fund invests in an operating business held through an LLC or partnership
- The underlying company generates active business income
- The investment involves leverage or debt
For example, if a private equity fund acquires a manufacturing company structured as an LLC, the income allocated to the IRA may be subject to UBTI, which is taxed at trust tax rates of up to 37 percent.
If the underlying business is structured as a C corporation, which is the case for most public companies, UBTI does not apply.
Before investing, it is wise to discuss fund structure and potential UBTI exposure with the fund sponsor and a knowledgeable Self-Directed IRA advisor.

Putting It All Together
Private equity is one of the fastest-growing asset classes inside Self-Directed IRAs. These investments are generally passive, involve relatively few transactions, and pose minimal prohibited transaction risk when the IRA owner has no personal involvement in the fund.
That said, investors must still carefully evaluate:
- Fund structure and entity type
- Potential UBTI or UDFI exposure
- Disqualified person rules
- Proper titling and documentation
When structured correctly, private equity can be a powerful tool for long-term, tax-advantaged retirement growth.
