Self-Directed IRA Custodian: Will They Stop You From a Bad Move?

“Custodian, TPA, attorney, CPA: who does what in a self-directed account, and will anyone stop me from a bad move?”

A self-directed IRA custodian holds your assets, but holding them isn’t the same as protecting you from a bad decision. In our September live Q&A, Laura Dohanes, CPA, mapped out who does what around a self-directed account, then asked guest John Bowens of Equity Trust Company the blunt question: if I tell you to wire money somewhere really stupid, will you stop me?

Quick answer: Only the obvious ones. A self-directed IRA custodian holds title and carries out your written instructions. It will typically stop a blatant prohibited transaction, but it won’t vet whether a deal is a good investment, and it doesn’t give tax, legal or investment advice. Compliance is yours, so build a team: the custodian (or a Solo 401(k) provider), an attorney for documents, and a CPA for strategy and tax.

Who does what around a self-directed account

• Custodian: required for an IRA. Holds title to the assets and executes your written instructions.
• Third-party administrator (TPA) / plan provider: for 401(k)s. Handles plan compliance and prepares the Form 5500 series (a one-participant plan generally files Form 5500-EZ once plan assets exceed $250,000).
• Attorney: drafts plan documents, LLC and entity documents, operating agreements and the agreements between you, your plan and other investors.
• CPA: connects compliance with strategy: how much you can put in, how to avoid over-contributing, how much you can take out, and how to avoid the tax bill that hits when it’s done wrong.

Does a Solo 401(k) need a custodian?

Not the way an IRA does. A Solo 401(k) doesn’t need a custodian, but it does need an IRS-approved plan document, a recordkeeping system and a service provider. Many firms offer both self-directed IRAs and Solo 401(k)s, and they work similarly; there are just subtle differences in how you direct money out of the account. Either way, you’re in control, and the provider will be clear that it doesn’t give tax, legal or financial advice.

What a self-directed IRA custodian will and won’t catch

Custodians, including Equity Trust, look for blatant prohibited transactions and will typically stop them. But there are subtle ones and gray areas, and some investors want to be more aggressive. And on the economics, the answer is plain: a custodian doesn’t perform due diligence on the merits of an investment. Whether it’s a good deal is up to you. A custodian can usually answer basic questions (the core prohibited transaction rules, how to move money in and out); strategy and nuanced tax questions belong with a licensed professional.

So who’s responsible? You

Laura’s takeaway: compliance on a self-directed account is always yours. You sign off on it and the penalty is yours, never the custodian’s. And your accountant can’t open the account or move money for you. Each specialist has a role, and none of them can do the others’ jobs.

It takes a team

Most people are drawn to these accounts for the Roth (tax-free growth), so start with the goal and build the map: who do you need in your corner? The custodian; a TPA if you’ll have a Solo 401(k) (for self-employed clients, Laura’s firm often uses both accounts); a CPA laying out the strategy ahead of time; and an attorney, because everything you do needs documents and agreements — that’s your best defense. When you’re stuck, ask which piece is missing: a custodian question, a strategy or tax question, or a legal one.

Key takeaways

• A custodian holds title and executes your instructions, but it doesn’t give tax, legal or investment advice.
• A Solo 401(k) needs a plan document, recordkeeping and a provider, but not an IRA-style custodian.
• Custodians typically stop blatant prohibited transactions, not gray-area ones or bad investments.
• Compliance and penalties are always the account owner’s responsibility.
• Build a team: custodian or plan provider, attorney and CPA, coordinated before the deal.
