What Is a Self-Directed IRA? How It Differs From a Regular IRA

A self-directed IRA is a retirement account that lets you invest in alternative assets — real estate, private equity, precious metals, crypto, farmland, and more — that traditional IRAs and 401(k)s don't allow. The tax benefits are identical to a standard IRA (tax-deferred growth in a Traditional, tax-free growth in a Roth), but the investment options expand dramatically. A self directed IRA puts you in the driver's seat, replacing the stock-and-bond menu at Fidelity with nearly unlimited asset choices.

How a Self-Directed IRA Works

Every IRA needs a custodian — a financial institution that holds the assets and handles tax reporting. Regular IRA custodians like Vanguard or Schwab limit your investments to stocks, bonds, mutual funds, and ETFs. A self directed IRA uses a specialized custodian that allows (and has the administrative infrastructure to support) alternative investments.

The mechanics: you open an account with a self-directed IRA custodian, fund it via contribution or rollover from an existing retirement account, and then direct the custodian to invest in specific assets. The custodian executes the transactions, holds the assets in the IRA's name, and ensures IRS compliance.

The IRA owns the asset, not you personally. Rental income from an IRA-owned property flows back into the IRA. Dividends from a private equity deal go into the IRA. You don't touch the money until you take distributions in retirement.

Self-Directed IRA vs. Regular IRA

The tax structure is identical. Both offer Traditional (tax-deductible contributions, taxed withdrawals) and Roth (after-tax contributions, tax-free withdrawals) options. Both have the same annual contribution limits — $7,000 in 2026 ($8,000 if you're 50 or older).

The difference is purely about what you can invest in.

Regular IRA: Stocks, bonds, ETFs, mutual funds, CDs. That's essentially it.

Self directed IRA: Everything above plus real estate, private placements, precious metals, tax liens, promissory notes, LLCs, farmland, cryptocurrency, and more.

The prohibited list is short. You cannot invest in life insurance, collectibles (with exceptions for certain coins and bullion), or S-corporations. You also cannot transact with "disqualified persons" — yourself, your spouse, parents, children, and certain business partners. This last rule trips up more investors than any other.

Types of Self-Directed IRA Custodians

Traditional SDIRA Custodians

Companies like Equity Trust act as the custodian, holding assets and processing transactions. You identify the investment, submit paperwork, and the custodian executes. This model works well for straightforward alternatives but can be slow — each transaction requires custodian approval and processing, which can take days to weeks.

Equity Trust has over $40 billion in assets under custody and handles everything from real estate closings to private company stock purchases.

Checkbook Control / LLC Structure

Companies like Rocket Dollar use a "checkbook control" structure. Your IRA forms an LLC, and you're the manager of that LLC with signing authority on its bank account. When an investment opportunity arises, you write a check from the LLC — no need to wait for custodian processing.

This speed advantage matters for time-sensitive deals like real estate purchases. The trade-off is more responsibility: you must ensure every transaction complies with IRS rules, because the custodian isn't reviewing each one. Annual fees typically run $15-$30 per month.

Platform-Integrated SDIRA

Alto IRA integrates directly with alternative investment platforms. Rather than handling asset custody yourself, Alto connects to platforms like AngelList, Republic, and various real estate sites, letting you invest IRA funds directly through those platforms' interfaces. This is the most user-friendly approach for investors who want to access platform deals with IRA dollars.

Alto's fees are among the lowest — $10/month for their starter plan — and they've removed much of the paperwork friction that plagues traditional SDIRA custodians.

What You Can Invest In

The range of assets available through a self directed IRA is vast:

Real estate is the most popular SDIRA investment. You can buy rental properties, raw land, commercial buildings, or invest in real estate crowdfunding deals. The IRA must pay all expenses (taxes, repairs, insurance) and receive all income. You cannot live in or personally use the property.

Private equity and venture capital deals structured as LLCs or LPs can be held in an SDIRA. When a startup you invested in through your IRA exits, the proceeds return to your IRA tax-deferred or tax-free.

Precious metals — specifically IRS-approved gold, silver, platinum, and palladium coins and bullion — can be held in an SDIRA through an approved depository.

Cryptocurrency has become increasingly popular. Alto IRA and others offer direct crypto investing within the IRA wrapper, and gains grow tax-advantaged.

Promissory notes and private lending let your IRA act as a lender, earning interest income that flows back to the account.

The Prohibited Transaction Rules

This is where self directed IRA investing gets tricky. The IRS strictly prohibits "self-dealing" — transactions that benefit you personally rather than your retirement account.

Disqualified persons cannot transact with your IRA. This includes you, your spouse, your parents, your children, and entities they control. You cannot sell property you own to your IRA. You cannot hire your construction company to renovate an IRA-owned rental. You cannot rent an IRA-owned vacation home to your kids.

Prohibited transactions include:

• Lending IRA money to yourself or disqualified persons
• Using IRA property for personal benefit
• Receiving compensation for managing IRA assets
• Buying property from or selling property to disqualified persons

Violating these rules doesn't just generate a penalty — the IRS treats the entire IRA as distributed, triggering income tax on the full balance plus a 10% early withdrawal penalty if you're under 59½. On a $500,000 IRA, that could mean a $200,000+ tax bill. Don't cut corners.

Fees and Costs

Self directed IRA fees typically exceed regular IRA fees because of the administrative complexity.

Alto IRA: $10/month (Starter) or $25/month (Pro). No per-transaction fees on most investments.

Rocket Dollar: $15/month (Silver) or $30/month (Gold). Includes checkbook control LLC formation.

Equity Trust: Fee schedule varies by asset type and account value. Annual fees typically range from $225-$2,250. Per-transaction fees may apply.

Compare fees against the tax savings. If your SDIRA saves you $5,000 per year in taxes on alternative investment returns, a $300 annual fee is trivial. If your account is small and returns are modest, the fees may eat into the tax benefit.

When a Self-Directed IRA Makes Sense

A self directed IRA works best when you're already investing in alternatives and want tax-advantaged growth. If you're investing $50,000 in a real estate syndication that will generate 8% annual returns over 5 years, holding it in a Roth SDIRA means $20,000+ in gains that you'll never pay tax on.

It doesn't make sense for everyone. If you're happy with stock and bond returns, a regular IRA at Vanguard with zero fees is simpler. If you don't understand alternative investments yet, adding an SDIRA layer of complexity won't help.

Frequently Asked Questions

What is a self-directed IRA and how is it different from a regular IRA?

A self-directed IRA has the same tax benefits as a traditional or Roth IRA but allows investments beyond stocks and bonds. You can hold real estate, private equity, precious metals, cryptocurrency, and other alternatives. The key difference is the custodian — SDIRAs use specialized custodians equipped to handle non-traditional assets.

Can I roll over my 401(k) into a self-directed IRA?

Yes. You can roll over funds from a 401(k), traditional IRA, or other qualified retirement accounts into a self-directed IRA without tax consequences. The rollover follows standard IRA rules — direct rollovers (trustee to trustee) are cleanest. You maintain the same tax treatment: traditional-to-traditional or Roth-to-Roth.

What are the contribution limits for a self-directed IRA?

The same as any IRA: $7,000 per year in 2026, or $8,000 if you're 50 or older. These limits apply across all your IRAs combined — you can't contribute $7,000 to a regular IRA and another $7,000 to an SDIRA. Rollovers from other retirement accounts don't count against these limits.

Can I buy real estate with a self-directed IRA?

Yes, real estate is the most popular SDIRA investment. Your IRA can purchase rental properties, commercial buildings, raw land, or invest in real estate crowdfunding. The IRA must pay all property expenses and receive all income. You cannot personally use the property or perform labor on it — hire third-party managers and contractors.

What happens if I make a prohibited transaction?

The IRS treats the entire IRA as distributed on the first day of the year the violation occurred. You owe income tax on the full account balance plus a 10% penalty if you're under 59½. On a $200,000 account, that's potentially $80,000+ in taxes and penalties. This is the single biggest risk of self-directed IRA investing.

Which self-directed IRA custodian should I choose?

It depends on your investment strategy. Alto IRA is best for investing through online alternative platforms with minimal fees. Rocket Dollar suits investors who want checkbook control for time-sensitive deals like real estate. Equity Trust handles the widest range of asset types with full custodial service.
