IRA Investing: What a Self-Directed IRA Allows

Your Broker's Menu Isn't the Law. It's a Business Decision

I spent years signing off on QA jobs aboard a fast-attack submarine, where the rule was simple: verify before you trust. Nobody's word was good enough on its own. Apply that same rule to your IRA and something uncomfortable falls out: the menu your brokerage shows you was never handed down by the IRS. It's a business decision, made by a company that isn't built to hold or value anything it can't price on a screen. That decision has quietly convinced millions of investors that stocks, bonds, and mutual funds are the whole game. (source: the IRS)

They're not. This piece draws the line between the standard IRA and the self-directed IRA, plainly, so you know which one you actually have and what it lets you do.

Why the Word "IRA" Hides Two Very Different Products

When most people say "IRA investing," they mean choosing between index funds and target-date funds inside a Fidelity or Vanguard account. That's one product. A self-directed IRA (SDIRA) is a second, legally distinct product, built on the exact same IRC Section 408 framework, held at a different kind of custodian, and opened to a far wider asset universe, according to the IRS. Confusing the two is how investors end up disappointed by their broker's menu, or blindsided by rules they never knew applied to their account.

What Can I Actually Hold in a Self-Directed IRA?

A self-directed IRA pairs the same tax-advantaged account with a custodian that specializes in holding non-traded assets: real estate, private equity and venture positions, private credit and notes, and precious metals, among others. The custodian's job stays administrative. It holds the asset. It processes paperwork. It files the required IRS forms. It does not vet your deal, independently value your property, or guarantee anything you put inside the account.

That underwriting is entirely yours.

Standard Custodian vs. Self-Directed Custodian: The Real Difference

At a conventional brokerage, the custodian pre-approves the menu. You pick from publicly traded stocks, bonds, mutual funds, and ETFs. You do not get to direct the custodian to buy a rental duplex, fund a friend's LLC, or hold a promissory note, even though nothing in the tax code forbids it. The brokerage's compliance and operations systems aren't built to hold or value non-traded assets. So they don't offer to.

That's a business decision by the custodian, not a limit imposed by the IRS. It's also why most investors have never heard that anything else is possible.

	Standard brokerage IRA	Self-directed IRA
Tax treatment	IRC Section 408, same rules	IRC Section 408, same rules
Asset menu	Stocks, bonds, mutual funds, ETFs	Real estate, private equity, private credit, notes, precious metals
Who vets the investment	Custodian's platform, indirectly, via what it lists	You, entirely
Contribution limits	Same IRS limits apply	Same IRS limits apply
Required minimum distributions	Same age rules apply	Same age rules apply
Prohibited transaction risk	Low, because the menu is pre-screened	High, if you deal with a disqualified person or self-deal

Do Traditional and Roth Rules Change Inside an SDIRA?

No. Moving to a self-directed custodian does not change how much you can contribute or when you must start pulling money out. The IRS sets one set of limits regardless of custodian. For 2024, the contribution ceiling was "$7,000, or $8,000 if you're age 50 or older by the end of the year," per the IRS — verify the current-year figure before you fund anything, because these numbers move annually. Traditional IRA holders must also begin required minimum distributions on the same schedule, since "you must start taking distributions by April 1 following the year in which you turn age 72," per the same source.

A self-directed IRA holding an illiquid rental property still has to generate a distribution on that schedule regardless. That's a liquidity problem worth planning for years before the deadline arrives, not the week it does.

What Happens If I Cross the Prohibited Transaction Line?

The standard brokerage protects you from prohibited transactions by never offering the assets that create them. A self-directed custodian does not. You can, legally, buy real estate inside an SDIRA. You cannot buy a house you or a disqualified family member will live in, and you cannot pay yourself to manage the property. Cross that line and the IRS can disqualify the entire account retroactively — not just the transaction.

Downside first: every asset you add to an SDIRA menu is downside you now own outright, not diversification you get for free. That's the single most consequential difference between the two products.

An example of what "downside first" catches: real estate held inside an SDIRA looks nothing like farmland held the same way: different custodial requirements, different liquidity, different failure modes. See what farmland inside an SDIRA actually returns before you assume one alternative asset behaves like another.

How Much Do Fees Actually Cost You Over Decades?

Custodian type isn't the only variable that compounds over a career. Fund-level fees do too, in either kind of IRA. The Pew Charitable Trusts modeled two savers with identical contributions and returns, one in a 2.05%-fee fund, one in a 0.05%-fee fund. The result: "After 40 years, she would have about $306,000 less than Elinor." That gap has nothing to do with which custodian's logo sits on the statement. It has everything to do with what you're paying to hold the asset.

The same math shows up in the aggregate. Median combined 401(k)/IRA balances for households nearing retirement rose from $135,000 in 2016 to $144,000 in 2019, according to the Center for Retirement Research at Boston College. Balances for people 35 to 44 moved the other way, falling from $63,500 in 2019 to $50,000 in 2022, according to CNBC, citing the same research center. My read: fee drag is a likely driver of that gap, not bad luck, though the data here shows balances moving, not what caused it.

In an SDIRA, sponsor fees, asset management fees, and custodian fees stack in ways a brokerage fund's expense ratio never does. Read the fee stack before you fund the deal, not after.

Common Mistakes

• Assuming the custodian approved the deal. A self-directed custodian holding an asset is not evidence anyone vetted it. That responsibility never left your desk.
• Chasing marketed return numbers. One custodian's product was marketed on the claim that it could "accelerate long-term average annual returns to 20%," according to InvestmentNews. A return projection that far outpaces the market is a claim to interrogate, not a number to bank on.
• Forgetting the RMD clock applies to illiquid assets too. A rental property or private fund position doesn't get an exception when the distribution deadline arrives.
• Treating a disqualified-person rule as a technicality. It's the rule most likely to disqualify the whole account, not just one transaction.
• Comparing custodians on monthly fee alone. Setup fees, per-asset fees, and transaction fees vary widely across providers and change the real cost of holding an illiquid position for years.
• Sizing a seven-figure illiquid position without a distribution plan. If most of the account is one non-traded asset, you need to know how you'll fund the RMD years before it's due, not after the notice arrives.

FAQ

Are IRAs a good investment? An IRA is a tax wrapper, not an investment itself. Whether it's good depends entirely on what you hold inside it and what it costs you in fees, not on the account type.

What if I invest $1,000 a month for 5 years? At $1,000 a month for five years you'd contribute $60,000. Fee drag matters more than the return you hope for: a 2% fund fee compounds against you every year. So does liquidity: an illiquid SDIRA asset can't be touched if you need cash before your RMD clock starts.

What is an IRA in investing? An IRA is a tax-advantaged retirement account under IRC Section 408. It is not itself an asset. What you can hold inside it depends on whether your custodian is a standard brokerage or a self-directed specialist.

How do I invest in an IRA for beginners? Confirm first whether the assets you actually want to hold are even on your custodian's menu; most brokerage IRAs don't carry them. Fund within the IRS contribution limit for the year, and read the fee schedule line by line before you commit.

What counts as a prohibited transaction in a self-directed IRA? Buying or leasing an asset to yourself or a disqualified family member, paying yourself to manage an account asset, or using the IRA to benefit a disqualified person. Any of these can disqualify the entire account, retroactively, not just the transaction.

The Bottom Line

Pull your current IRA statement and check one line: does your custodian's menu match the assets you actually want to hold in retirement? If the answer is no, that's the conversation to have with a self-directed custodian and a qualified tax professional before you move a dollar. Wall Street's menu was never the whole market. It was just the part that was easy to sell you.
