Self-Directed IRAs Explained: What a Custodian Does—and Doesn't Do

How self-directed retirement accounts work, what investors can own through them, and where the custodian's responsibilities end.

For most Americans, an Individual Retirement Account (IRA) is associated with familiar investments: stocks, bonds, mutual funds, and exchange-traded funds held through a bank or brokerage firm.

But retirement accounts are not necessarily limited to investments traded on public exchanges.

Under the right arrangements, IRA assets can be invested in privately held businesses, real estate, private lending, and other alternative investments that are not typically available through conventional brokerage retirement accounts.

This broader investment flexibility is what people generally mean when they refer to a self-directed IRA, or SDIRA.

For individuals interested in private markets, self-directed IRAs can provide a way to invest retirement capital in opportunities outside traditional securities markets while retaining the tax treatment associated with their retirement accounts.

That flexibility also comes with an important distinction: the institution administering the account is not necessarily evaluating the investments held within it.

Understanding the difference between the account, its custodian, and the investments themselves is essential to understanding how self-directed IRAs work.

What Is a Self-Directed IRA?

A self-directed IRA is an Individual Retirement Account administered by a custodian that permits investments beyond the traditional securities typically offered by banks and brokerage firms.

Despite the name, a self-directed IRA is not a separate category of retirement account created by a different set of tax laws.

A self-directed IRA may be established as a traditional IRA or Roth IRA. The familiar rules governing contributions, distributions, and retirement-account tax treatment generally continue to apply.

The principal difference is the range of investments the account provider permits.

A conventional brokerage IRA may limit investors to publicly traded stocks, bonds, mutual funds, and similar financial products.

A self-directed IRA custodian may allow the account to hold private-company shares, real estate, private fund interests, promissory notes, and certain other alternative assets.

The distinction matters because the Internal Revenue Code does not broadly prohibit IRAs from owning private investments. Instead, it establishes rules governing what retirement accounts may own and how they must operate.

Not every custodian chooses to administer every legally permissible asset. Private investments often require specialized documentation, ownership records, valuation procedures, and transaction processing that conventional brokerage platforms are not designed to accommodate.

Self-directed IRA custodians provide the administrative infrastructure necessary to hold those investments within a retirement account.

Traditional vs. Roth Self-Directed IRAs

The self-directed designation does not change the underlying account's tax treatment.

A traditional IRA generally allows qualifying contributions to receive favorable tax treatment, with investment earnings ordinarily growing tax-deferred and distributions generally subject to applicable income taxes.

A Roth IRA is funded with after-tax contributions or certain converted amounts, and qualified distributions can be tax-free.

Both account types may hold alternative investments when supported by their custodians.

Investing through a self-directed IRA does not create an additional tax exemption or eliminate the rules governing retirement accounts. Certain investments can also generate tax obligations within an IRA, as discussed below.

How Do You Invest Through a Self-Directed IRA?

The investment process involves the retirement account owner, the custodian, and the company or investment sponsor offering the opportunity.

An investor typically begins by establishing an account with a custodian that supports the type of investment being considered.

The account may be funded through eligible contributions, transfers from another IRA, or rollovers from qualifying retirement plans.

A direct IRA-to-IRA trustee transfer generally moves assets between institutions without distributing the funds to the investor personally. Rollovers are governed by separate rules, including applicable deadlines and limitations.

Once the account is funded, the investor identifies an investment and provides the custodian with the necessary documentation and transaction instructions.

The custodian reviews the paperwork for its administrative requirements and, if the transaction is accepted under its policies, processes the investment on behalf of the IRA.

The resulting asset belongs to the retirement account, not directly to the individual account owner.

An Example: Investing in a Private Company

Suppose an investor has $100,000 in an existing traditional IRA and wants to commit $25,000 to an eligible private-company offering.

The investor opens a traditional self-directed IRA with a custodian that supports private-placement securities and arranges a direct transfer of retirement funds.

After reviewing the investment opportunity and its offering documents, the investor instructs the custodian to purchase the securities using $25,000 from the IRA.

The custodian processes the investment according to its procedures, and the ownership interest is recorded for the benefit of the IRA.

If the investment subsequently generates distributions, those proceeds generally return to the IRA rather than being paid directly to the investor personally.

The investor's retirement account now holds a private security alongside any other assets remaining in the account.

The custodian maintains the account records and processes applicable transactions.

However, the custodian's involvement does not establish whether the private company is financially sound, whether the offering is attractively priced, or whether the investment will produce the anticipated results.

Those are separate considerations.

What Does a Self-Directed IRA Custodian Actually Do?

Every IRA must be maintained by an eligible trustee or custodian, such as a qualifying bank, trust company, or IRS-approved nonbank institution.

A self-directed IRA custodian serves as the administrative institution responsible for maintaining the retirement account and processing transactions involving its assets.

Its responsibilities commonly include opening accounts, accepting eligible transfers and rollovers, maintaining account records, processing investment directions, handling cash movements, and administering distributions.

Custodians also perform applicable tax-information reporting, including Form 5498 for IRA information and Form 1099-R for reportable distributions.

When an IRA holds assets that are not publicly traded, the custodian must address the account's fair-market-value reporting requirements. Obtaining valuations may involve information provided by investment sponsors, account owners, or independent valuation professionals.

The custodian's processes and documentary requirements can vary depending on the assets involved.

For example, investing in a privately held company may require reviewing subscription paperwork and recording ownership interests. Holding directly owned real estate involves different documentation and ongoing administrative needs.

In both cases, the custodian helps maintain the retirement-account structure through which the investment is held.

This is an important service, particularly for investments that ordinary brokerage platforms do not accommodate.

But account administration and investment analysis are different responsibilities.

What Doesn't a Self-Directed IRA Custodian Do?

One of the most common misconceptions about self-directed IRAs is that a custodian's participation provides an additional layer of investment approval.

In general, it does not.

Most self-directed IRA custodians operate in a passive or directed capacity. They administer assets selected by the account owner rather than choosing investments or evaluating their economic merits.

The SEC, FINRA, and state securities regulators have specifically emphasized the limitations of this custodial role.

A Custodian Does Not Recommend or Evaluate Investments

A self-directed IRA custodian generally does not determine whether a private investment is appropriate for the account owner.

It does not ordinarily evaluate the underlying business model, investment strategy, projected returns, sponsor experience, or risks in the manner an investment research analyst might.

A custodian may accept the paperwork for a private placement without concluding that the offering represents an attractive investment.

The decision to invest remains with the account owner.

A Custodian Does Not Verify a Sponsor's Claims

Private investment offerings often include financial projections, asset valuations, historical performance information, and descriptions of management experience.

A custodian typically does not independently verify those claims.

For example, a private real estate sponsor might report that a property has increased substantially in value. The custodian may use sponsor-provided information as part of its valuation reporting process without independently appraising the property or validating the sponsor's underlying assumptions.

Although custodians have obligations concerning annual account valuation and reporting, those obligations should not be confused with a comprehensive independent valuation or due-diligence engagement.

An investment appearing on a custodian's account statement does not establish that its reported value is accurate or that the investment has been independently evaluated.

A Custodian Does Not Guarantee an Investment's Legitimacy or Performance

A legitimate custodian can administer an investment that ultimately fails or is found to involve misconduct.

The custodian's acceptance of investment documentation is not an SEC endorsement, a guarantee of repayment, or confirmation that the investment sponsor has been thoroughly investigated.

Likewise, the fact that an investment can be held in an IRA does not establish that the investment is appropriate for retirement capital.

Custodians may reject transactions that fall outside their policies or administrative capabilities. Such decisions should not be interpreted as comprehensive judgments about an investment's quality or legal compliance.

This separation of responsibilities is central to the self-directed IRA model: the custodian administers the account, while the investor selects and evaluates the investments.

What Rules and Risks Should Investors Understand?

The flexibility of a self-directed IRA does not remove the legal requirements governing retirement accounts.

Several rules deserve particular attention because violations can create consequences beyond the investment's ordinary financial risks.

Prohibited Transactions and Personal Benefit

Federal tax law restricts certain transactions between an IRA and its owner or other parties classified as disqualified persons.

These rules are intended to prevent retirement-account assets from being used for improper personal benefit.

For example, an IRA owner generally cannot purchase a vacation property through their IRA and then use it personally. Selling personally owned property to the IRA, borrowing from the account, or pledging IRA assets as security for a personal loan can also violate prohibited-transaction rules.

The consequences can be severe. Certain prohibited transactions involving the IRA owner or beneficiary can cause the account to lose its IRA status, potentially resulting in substantial taxable distributions and additional taxes.

Investors should distinguish between an investment being permitted as an asset category and a particular transaction being permissible under retirement-account rules.

An IRA may generally invest in real estate, for example, but that does not mean every real estate transaction involving the account owner is allowed.

Investment Restrictions and Potential Taxes

IRAs cannot invest in certain prohibited assets, including life insurance contracts and most collectibles, although specific exceptions exist for qualifying precious metals and coins.

Some alternative investments may also generate unrelated business taxable income (UBTI) or unrelated debt-financed income (UDFI).

Under applicable circumstances, an IRA can owe taxes on this income even though it is otherwise a tax-advantaged retirement account.

That distinction can be relevant when investing in operating businesses, partnerships, or leveraged real estate.

Investors should also consider how illiquid assets affect required minimum distributions, where applicable, and the availability of cash to pay account expenses or tax obligations.

The tax treatment of an investment depends on its structure and circumstances, not simply on the fact that it is owned through an IRA.

Investment Risk and Limited Liquidity

Self-directed IRAs can hold assets that are difficult to value or sell.

Private-company shares, real estate interests, private loans, and other alternative investments may have limited financial disclosures, no established secondary market, and holding periods extending over many years.

An investment may underperform or lose its entire value.

Because the investment is held inside a retirement account, its liquidity can also affect the investor's ability to respond to future retirement needs.

The account structure does not change the underlying economics of the investment.

Choosing a Custodian—and Understanding Your Own Responsibilities

Not all self-directed IRA custodians provide the same services.

Some specialize in private placements and fund interests. Others emphasize directly owned real estate, precious metals, or additional alternative assets.

When comparing custodians, investors should consider the investments supported, administrative experience, processing procedures, reporting capabilities, fees, and responsiveness.

It is also important to verify the institution's authority to serve as an IRA custodian. The IRS maintains a list of approved nonbank trustees and custodians, while qualifying banks may serve under separate rules.

Fees may include account establishment charges, annual administration fees, asset-based charges, transaction processing fees, and other expenses depending on the provider.

Beyond selecting the custodian, investors remain responsible for evaluating the investments they direct their accounts to purchase.

That evaluation may involve reviewing offering documents, researching the sponsor, examining financial assumptions, understanding fees and contractual rights, and considering the implications of holding an illiquid investment within a retirement account.

Legal and tax professionals can address questions involving retirement-account restrictions, prohibited transactions, and potential tax obligations. Independent investment research serves a different purpose: assessing the people, assets, economics, assumptions, and evidence behind the opportunity itself.

Each has a distinct role.

The Difference Between Access and Investment Evaluation

Self-directed IRAs provide a useful connection between retirement savings and investments beyond conventional public-market securities.

They allow qualifying investors to hold certain private investments through retirement accounts while maintaining the applicable IRA framework.

The custodian makes that arrangement administratively possible. It maintains the account, processes transactions, keeps records, and fulfills reporting responsibilities.

But the custodian is not ordinarily responsible for determining whether an investment deserves the investor's capital.

That distinction becomes especially important when the underlying assets are private, difficult to value, or supported primarily by information provided by the issuer or investment sponsor.

A self-directed IRA expands what an investor may be able to own within a retirement account. It does not transfer responsibility for understanding those investments to the institution administering them.

For individuals exploring private markets with retirement capital, understanding both sides of that relationship is an essential part of participating thoughtfully.
