A self-directed trust is a trust in which the grantor, or an advisor the grantor names, controls how the trust’s assets are invested rather than handing that power to a professional money manager. That control is what makes the structure distinctive: the trust can hold real estate, shares in private companies, promissory notes, and certain precious metals, not just stocks and bonds. The tradeoff is that whoever directs the investments carries the fiduciary responsibility that would otherwise sit with a corporate trustee, and federal rules on prohibited transactions can erase the trust’s tax advantages if they are broken.
Two Different Things Called by the Same Name
The phrase gets used in two settings, and the rules differ in each.
In estate planning, “self-directed trust” usually refers to a directed trust. The trust document splits the traditional trustee role: one party handles administration, and a separate person or firm, often called a trust director or advisor, controls investment decisions. These arrangements are governed by state trust law.
In retirement planning, the term often describes a trust held inside a self-directed IRA. The account owner picks alternative investments and a specialized custodian holds them. These are governed by federal tax law, mainly Internal Revenue Code Sections 408 and 4975.
Both share the same core idea: the person closest to the assets makes the investment calls. But knowing which version you have determines which rules you have to follow.
How a Directed Trust Divides the Work
A traditional trust puts one trustee in charge of investments, distributions, recordkeeping, and compliance. A directed trust separates those duties. The trust document names a trust director (sometimes called an advisor or protector) who controls investment decisions. An administrative trustee handles paperwork, custody of assets, and compliance filings. The grantor creates and funds the trust; the beneficiary receives its benefits.
The Uniform Directed Trust Act, adopted in some form by a growing number of states, sets how liability is divided. Under the UDTA, the trust director carries fiduciary responsibility for investment decisions, the same responsibility a traditional trustee would have. The administrative trustee follows the director’s lawful instructions and is liable only for willful misconduct. If the director picks a bad investment and the trust loses money, the administrative trustee is generally not on the hook. The state whose law governs the trust shapes how strong that protection is, so the choice of governing law matters.
Trust directors are not limited to picking stocks. Depending on the drafting, a director may decide when and how much to distribute, direct the sale of specific assets, vote shares of trust-owned businesses, or run a business held inside the trust.
What a Self-Directed Trust Can Hold
Self-directed trusts can hold asset types most brokerages will not touch. Common categories include:
- Real estate. Residential or commercial property, rental property, and raw land, with the deed recorded in the trust’s name.
- Private equity. Shares in privately held companies, limited partnership interests, and LLC membership interests.
- Precious metals. Gold, silver, platinum, or palladium bullion meeting the minimum fineness required for delivery on regulated futures contracts, plus American Eagle coins and certain state-minted coins.1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts
- Private debt. Promissory notes, tax lien certificates, and private mortgage lending.
- Cryptocurrency. Some custodians now support digital assets, though options are more limited.
Every asset must be titled in the trust’s name. For real estate, the deed names the trust (or an LLC owned by the trust). For private company shares, the stock certificate or operating agreement lists the trust as holder.
What It Cannot Hold
For trusts inside retirement accounts, federal law bans specific categories. Life insurance contracts cannot be held in an IRA trust. Collectibles are also prohibited: artwork, antiques, rugs, gems, stamps, wine, and most coins. If the trust acquires a collectible, the IRS treats the purchase as a taxable distribution to the account holder.1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts
S-corporation stock is a separate trap. While the grantor is alive, a revocable trust usually qualifies as a grantor trust and can hold S-corp stock. After the grantor dies, the trust has only two years to remain an eligible shareholder before the corporation risks losing its S-election. To hold the shares longer, the trust must qualify as either a Qualified Subchapter S Trust (QSST) or an Electing Small Business Trust (ESBT). A QSST can have only one income beneficiary, who must be a U.S. citizen or resident, and all income must be distributed currently. An ESBT allows multiple beneficiaries and can accumulate income, but the trust pays tax on S-corp income at the highest individual rate.
Setting Up and Funding
Most standard banks and brokerages will not custody alternative assets. A self-directed trust needs a specialized custodian or trust company that handles non-traditional holdings. The custodian you pick determines which asset types are available, what fees you pay, and how transactions get processed. Setup fees typically run $50 to $300, with annual custodial fees from roughly $199 to $2,000 depending on asset types and account complexity. Transaction fees are separate.
For compliance and anti-money laundering purposes, you provide full legal names, addresses, and Social Security numbers for the grantor, trustee, and all beneficiaries, including contingent beneficiaries. Documentation for the initial assets is required, such as a property deed or private stock certificates. The trust agreement should designate a successor trustee in case the primary directing party becomes incapacitated.
Funding happens through a cash transfer or by retitling an existing asset into the trust’s name. If you are moving funds from a qualified retirement account into a self-directed IRA trust, use a direct rollover: funds pass from one custodian to another without going through your hands. An indirect rollover triggers mandatory 20% withholding, and if the paperwork or timing goes wrong you can owe income tax on the entire amount, plus a 10% early distribution penalty if you are under 59½.
Annual Valuation
Many self-directed trust assets have no daily market price. If the trust holds real estate, private company stock, or other hard-to-value assets, you need an accurate fair market value at least once a year. For trusts inside IRAs, custodians report the fair market value of all account assets to the owner and the IRS on Form 5498.
Valuation usually requires documentation from an independent third party. For real estate, that might be a broker’s price opinion or a comparable market analysis. For private company shares, a qualified appraiser typically provides a written valuation with a clear methodology. If a valuation shifts by more than 50% year over year, expect the custodian to ask for additional support. Accurate values also matter for required minimum distributions, Roth conversions, and settlement of the trust after death.
Prohibited Transactions
This is where self-directed trusts carry real risk. The IRS restricts transactions between the trust and people connected to it, and the penalties can wipe out the account.
Who Counts as a Disqualified Person
Under IRC Section 4975, “disqualified persons” include the trust’s fiduciary, anyone providing services to the plan, and family members of those people. For an IRA, the account owner is treated as the fiduciary. Family members include the owner’s spouse, parents, grandparents, children, grandchildren, and the spouses of children and grandchildren.2Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions Entities where disqualified persons hold 50% or more ownership also count. Siblings do not.
What You Cannot Do
The rules bar any direct or indirect transaction between the trust and a disqualified person. Common violations:
- Personal use of trust property. If the trust owns a vacation home, you cannot stay in it. Your children cannot stay in it. Any personal use by a disqualified person is a prohibited transaction.
- Providing services to the trust. You cannot personally renovate a property the trust owns, even without charging for the work. Sweat equity counts.
- Lending or borrowing. The trust cannot lend money to you or your family, and you cannot lend money to the trust.
- Receiving compensation. A disqualified person cannot receive payment from the trust for goods, services, or facilities.2Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions
What the Penalties Look Like
The initial excise tax is 15% of the amount involved, assessed for each year or partial year the violation goes uncorrected.3Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions If the problem is not fixed within the taxable period, a second tax of 100% of the amount involved applies.
For IRA-based trusts, the consequences are harsher. Under IRC Section 408, if the IRA owner or beneficiary engages in a prohibited transaction, the account stops being an IRA as of the first day of that taxable year. The IRS then treats the entire account balance as distributed. You owe income tax on the full fair market value of every asset, and potentially an early distribution penalty on top.1Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts One mistake can produce a tax bill larger than the original transaction.
Unrelated Business Income Tax
Even a tax-advantaged trust can owe tax on certain investment income. When a self-directed trust earns income from an active trade or business, rather than passive returns like dividends or rent, that income can trigger Unrelated Business Income Tax. The usual culprits are limited partnership and master limited partnership investments that generate operating income, and income from debt-financed property.
If the total positive unrelated business taxable income across all investments in the account reaches $1,000 or more, the trust must file IRS Form 990-T and pay the tax. This surprises people who assume everything inside a retirement account is tax-deferred. Check your K-1 forms each year, particularly line 20-V, for UBTI.
What the Custodian Actually Does
One of the most misunderstood points: a self-directed custodian does not vet your investments. The SEC has issued a specific investor alert on this. Self-directed IRA custodians do not evaluate the quality or legitimacy of any investment, do not verify the accuracy of financial information provided by promoters, and do not provide investment advice.4U.S. Securities and Exchange Commission. Investor Alert – Self-Directed IRAs and the Risk of Fraud Their job is to hold and administer assets, nothing more.
Fraudsters work this gap. Promoters steer investors toward worthless or fictitious assets inside self-directed accounts, sometimes using fake custodians, sometimes falsely implying that the custodian’s involvement means the investment has been reviewed. The SEC warns that the tax-deferred nature of these accounts can work against investors as well, since the prospect of early withdrawal penalties discourages close scrutiny.
Before directing the trust to buy any alternative asset, verify the investment, the promoter’s background, and the custodian’s legitimacy yourself. No one else in the chain is doing it for you.
