What Is a Self-Directed IRA?

A self-directed IRA (SDIRA) is an individual retirement account that gives you control over a broader range of investments than a traditional IRA — including private equity, commercial real estate, private credit, and other alternative assets — while preserving the same tax advantages.

With a standard IRA through a brokerage like Fidelity or Vanguard, your investment options are typically limited to stocks, bonds, and mutual funds. A self-directed IRA removes that restriction. The tax treatment is identical — what changes is what you're allowed to hold inside the account.

How Does a Self-Directed IRA Work?

A self-directed IRA functions like any other IRA in terms of contributions, tax treatment, and withdrawal rules. The key difference is the custodian.

Standard IRAs are held at brokerages that only offer publicly traded securities. A self-directed IRA is held at a specialized custodian — a trust company or financial institution approved by the IRS to administer accounts holding alternative assets. The custodian holds and administers the assets but does not evaluate or advise on investments. That responsibility falls to you, the account holder — though many investors work with a financial advisor who helps identify, evaluate, and oversee investments on their behalf.

Once your SDIRA is established and funded, you direct the custodian to make investments on your behalf — into a private equity fund, a real estate deal, a private credit offering, and so on.

What Can You Invest in With a Self-Directed IRA?

Self-directed IRAs can hold a wide range of assets, including:

  • Private equity — stakes in private companies or growth-stage funds
  • Commercial real estate — direct property ownership or real estate funds
  • Private credit — loans, notes, and debt instruments
  • Energy and infrastructure — direct participation programs and energy funds
  • Precious metals — gold, silver, and other IRS-approved metals
  • Cryptocurrency — digital assets through qualified custodians

The IRS does prohibit certain assets inside an IRA, including life insurance contracts, collectibles (art, antiques, wine), and S-corporation stock. Any investment should be reviewed against IRS guidelines before proceeding.

What Are the Tax Advantages of a Self-Directed IRA?

Self-directed IRAs come in two forms, each with distinct tax treatment:

Traditional Self-Directed IRA

Contributions may be tax-deductible depending on your income and whether you have access to an employer plan. Investments grow tax-deferred, meaning you pay no taxes on gains until you take distributions in retirement.

Roth Self-Directed IRA

Contributions are made with after-tax dollars. Investments grow tax-free, and qualified distributions in retirement are also tax-free. For long-hold, high-growth private market assets, the Roth structure can be especially powerful — gains that would otherwise be taxable compound entirely within the account.

Who Is a Self-Directed IRA Right For?

The most common path to a self-directed IRA is through money you already have — though new contributions are absolutely allowed as well. Anyone with a balance built up in an existing IRA, a 401(k) from a former employer, or in some cases a 401(k) from a current employer — if the plan permits what is known as an in-service rollover — can move those funds into an SDIRA and begin investing in a broader range of assets. In-service rollovers are plan-dependent, so it is worth checking your plan documents or speaking with your plan administrator.

It is worth noting that some of the investments available through an SDIRA — such as private equity funds, private credit, and certain real estate offerings — do require investors to meet the SEC's accredited investor definition. That is a requirement of those specific investments, not of the SDIRA structure itself. An SDIRA can also hold alternative assets that do not carry that requirement.

It is also worth noting that some assets held inside an SDIRA — particularly private equity, private credit, and real estate funds — tend to be illiquid and long-term in nature. That is a characteristic of those specific investments, not of self-directed IRAs as a structure.

How Do You Get Money Into a Self-Directed IRA?

There are several ways to fund a self-directed IRA, and for many investors the most significant source of capital is money they already have sitting in other retirement accounts.

Annual Contributions

You can contribute to an SDIRA the same way you would any IRA, up to the IRS annual limit ($7,000 in 2025 or $7,500 in 2026, with higher limits for those age 50 or older). These limits apply across all IRAs combined. You have until April 15, 2026 to make contributions for the 2025 tax year. Eligibility for deductible contributions or Roth contributions depends on your income and tax filing status.

IRA Transfer

If you have an existing traditional IRA or Roth IRA at a brokerage, you can transfer it directly to an SDIRA custodian. A transfer moves funds from one IRA to another of the same type — it is not a taxable event and has no 60-day deadline because the funds go directly between custodians without passing through your hands.

Rollover from a Former Employer Plan

A 401(k), 403(b), 457, or other qualified plan from a previous employer can be rolled over into a self-directed IRA. A direct rollover — where the funds go straight from the plan to the SDIRA custodian — avoids any withholding and is not a taxable event. This is one of the most common ways investors fund an SDIRA, particularly those who have accumulated significant balances in old workplace plans.

What Is a Prohibited Transaction?

The IRS has strict rules about what constitutes a prohibited transaction inside a self-directed IRA. In general, prohibited transactions involve self-dealing — using the IRA for your own benefit before retirement.

Examples include:

  • Purchasing a property in your SDIRA that you or a family member uses personally
  • Lending money from your SDIRA to yourself or a disqualified person
  • Paying yourself for services related to an SDIRA investment

Prohibited transactions can result in the entire account being treated as a distribution, triggering taxes and penalties. Working with a knowledgeable advisor and a reputable custodian is essential to staying compliant.
