What Is a Self-Directed IRA?
A self-directed IRA (SDIRA) is an individual retirement account that gives the account holder direct control over investment decisions and allows a significantly wider range of asset classes than a conventional IRA offered by a bank or brokerage. While a standard IRA at Fidelity or Vanguard restricts you to publicly traded securities (stocks, bonds, mutual funds, ETFs), an SDIRA can hold alternative assets such as:
- Cryptocurrencies (Bitcoin, Ethereum, and others)
- Precious metals (IRS-approved gold, silver, platinum, palladium)
- Real estate (residential, commercial, raw land)
- Private equity and venture capital
- Promissory notes and private lending
- Tax liens and deeds
The "self-directed" designation refers to the investor's role in directing investment decisions — not to the absence of a custodian. The IRS requires all IRAs, including SDIRAs, to be held by a qualified custodian or trustee. The custodian administers the account, maintains records, and ensures IRS compliance, but does not provide investment advice or evaluate the quality of your investment choices.
Important:
The IRS does not approve or endorse any specific SDIRA custodian, investment, or strategy. The existence of an SDIRA does not mean any particular investment is safe, suitable, or IRS-compliant. Investors bear full responsibility for verifying that their investments comply with IRS rules.
How SDIRAs Differ from Standard IRAs
| Feature | Standard IRA | Self-Directed IRA |
|---|---|---|
| Asset types | Stocks, bonds, ETFs, mutual funds | Crypto, metals, real estate, private equity, and more |
| Custodian type | Bank, brokerage, or robo-advisor | Specialized SDIRA custodian |
| Investment control | Limited to custodian's offerings | Investor directs all decisions |
| Due diligence | Custodian may screen investments | Investor bears full responsibility |
| Fees | Typically low (0–0.25%/yr) | Higher — setup, annual, transaction, storage fees |
| Complexity | Low | High — requires understanding of IRS rules |
| Fraud risk | Lower (regulated securities) | Higher — alternative assets are less regulated |
IRS-Eligible Asset Classes
The IRS permits SDIRAs to hold a wide range of assets, but also explicitly prohibits certain types. The following are generally permitted:
Cryptocurrencies
Bitcoin, Ethereum, and other digital assets. Must be held by a qualified custodian — you cannot take personal possession. The IRS treats crypto as property for tax purposes (Notice 2014-21).
Crypto in IRAs: Full Guide →Precious Metals
IRS-approved gold (≥99.5% purity), silver (≥99.9%), platinum (≥99.95%), and palladium (≥99.95%). Must be stored in an IRS-approved depository — not at home.
Precious Metals in IRAs: Full Guide →Real Estate
Residential, commercial, raw land, and rental properties. The IRA — not you personally — must own the property. All income and expenses must flow through the IRA.
Private Equity & Notes
Interests in private companies, LLCs, limited partnerships, and promissory notes. Subject to prohibited transaction rules if the counterparty is a disqualified person.
Prohibited Assets (IRC §408(m)):
Life insurance contracts, S-corporation stock, collectibles (art, antiques, rugs, gems, most coins), and alcoholic beverages are explicitly prohibited inside an IRA. Holding these triggers immediate distribution and potential penalties.
IRS Rules and Prohibited Transactions
The most important — and most frequently violated — SDIRA rules relate to prohibited transactions under IRC §4975. A prohibited transaction occurs when you engage in a transaction between your IRA and a disqualified person.
Disqualified persons include: you (the IRA owner), your spouse, lineal descendants (children, grandchildren), lineal ascendants (parents, grandparents), and any entity in which a disqualified person owns 50% or more.
Examples of Prohibited Transactions:
- ✗ Buying a property from your SDIRA and living in it (self-dealing)
- ✗ Lending IRA funds to yourself or a family member
- ✗ Storing IRA-owned gold or crypto in your personal possession ("home storage" IRAs are not IRS-approved)
- ✗ Paying yourself a salary to manage an IRA-owned property
- ✗ Selling your personal property to your IRA
Consequence of a Prohibited Transaction:
If a prohibited transaction occurs, the IRA is treated as distributing its entire fair market value on January 1 of the year the transaction occurred. This triggers ordinary income tax on the full amount, plus a 10% early withdrawal penalty if you are under age 59½. The IRA ceases to exist as a tax-advantaged account.
Tax Implications: Traditional vs. Roth SDIRA
| Feature | Traditional SDIRA | Roth SDIRA |
|---|---|---|
| Contributions | Pre-tax (may be deductible) | After-tax (not deductible) |
| Growth | Tax-deferred | Tax-free (if qualified) |
| Withdrawals in retirement | Taxed as ordinary income | Tax-free (if qualified) |
| Required Minimum Distributions | Yes — starting at age 73 | No RMDs during owner's lifetime |
| 2026 contribution limit | $7,000 ($8,000 if age 50+) | $7,000 ($8,000 if age 50+) |
| Income limits | None for contributions | Phase-out begins at $150,000 (single) / $236,000 (MFJ) |

Risks You Must Understand Before Investing
SDIRAs carry significantly higher risk than standard IRAs. The SEC and FINRA have both issued investor alerts specifically about SDIRA fraud and losses. Understanding these risks is essential before proceeding.
Alternative assets like cryptocurrencies and private equity can lose their entire value. Unlike FDIC-insured bank deposits, there is no government protection for SDIRA assets. You could lose everything you invest.
Cryptocurrency prices can decline 50–80% in a matter of months. Precious metals prices fluctuate with global economic conditions. These are not stable, income-producing assets suitable for all investors.
Many SDIRA assets (real estate, private equity, certain metals) cannot be quickly sold. If you need funds for an emergency or RMDs, you may be unable to liquidate in time without significant losses.
The SEC has warned that SDIRA promoters sometimes use the IRS-required custodian relationship to falsely imply government approval of investments. Custodians do not verify the legitimacy or quality of investments.
Many alternative assets lack transparent market pricing. Overvalued assets can inflate your IRA balance on paper while actual liquidation value is far lower.
Prohibited transaction rules are complex and easily violated. A single mistake can trigger taxation of your entire IRA balance plus penalties. Professional tax and legal guidance is strongly recommended.
The Role of the Custodian
Every SDIRA must be held by a qualified custodian — a bank, federally insured credit union, savings and loan association, or other entity approved by the IRS under IRC §408(a). The custodian's responsibilities include:
- Maintaining the IRA account and records
- Filing required IRS reports (Form 5498, Form 1099-R)
- Executing investment transactions at the account holder's direction
- Ensuring assets are held in the IRA's name (not the investor's personal name)
What Custodians Do NOT Do:
SDIRA custodians are not investment advisors. They do not evaluate the quality, safety, or legitimacy of your investment choices. They do not verify whether an investment is a good idea, whether a promoter is honest, or whether an asset is fairly valued. Due diligence is entirely your responsibility.
How to Research SDIRA Custodians Yourself
Before opening an SDIRA, independently verify the following about any custodian you are considering:
Verify IRS Approval
Confirm the custodian is a bank, trust company, or other IRS-approved entity. Ask for their charter number and verify with the relevant state banking regulator.
Check FINRA BrokerCheck
Search the custodian's name at brokercheck.finra.org to review any regulatory actions, complaints, or disciplinary history.
Review SEC EDGAR
Search sec.gov/cgi-bin/browse-edgar for any SEC filings or enforcement actions against the custodian.
Check BBB Accreditation
Review the custodian's BBB rating, accreditation status, and complaint history at bbb.org.
Request a Full Fee Schedule
Get the complete fee schedule in writing before opening an account. SDIRA fees can be complex — setup fees, annual fees, transaction fees, storage fees, and wire fees can add up significantly.
Understand Custody Arrangements
For crypto SDIRAs, ask specifically: who holds the private keys? Is storage cold (offline) or hot (online)? What insurance covers the assets? What happens if the custodian goes bankrupt?
