How to Use a Self-Directed IRA to Invest in Alternative Assets (2026)

A self-directed IRA for alternatives lets you hold private credit, real estate, precious metals, startups, and other non-traditional assets inside a tax-advantaged retirement account. Instead of limiting your IRA to stocks and mutual funds, you gain access to the same alternative investments available in taxable accounts — but with tax-deferred or tax-free growth. Platforms like Alto IRA, Rocket Dollar, and Equity Trust make opening and funding a self-directed IRA straightforward.

What Is a Self-Directed IRA?

A self-directed IRA (SDIRA) follows the same IRS rules as a regular IRA — same contribution limits ($7,000 in 2026, $8,000 if over 50), same tax advantages, same early withdrawal penalties. The difference is the custodian. Traditional IRA custodians (Fidelity, Schwab, Vanguard) restrict you to publicly traded securities. SDIRA custodians allow alternative investments.

You still need a custodian — the IRS requires one for all IRAs. But SDIRA custodians are specifically set up to handle the paperwork, compliance, and asset custody for non-traditional holdings. They don't give investment advice; they process transactions and file the required IRS reports.

The "self-directed" part means you choose the investments. The custodian facilitates but doesn't recommend. This freedom comes with responsibility — you need to understand what you're buying, because the custodian won't stop you from making a bad investment.

What You Can (and Can't) Hold in an SDIRA

Allowed Investments

• Real estate (residential, commercial, raw land)
• Private credit and promissory notes
• Precious metals (gold, silver, platinum meeting IRS purity requirements)
• Private company equity and startup shares
• Cryptocurrency
• Tax liens and deeds
• Music royalties
• Farmland
• LLCs and partnerships

Prohibited Investments

• Life insurance
• Collectibles (art, wine, stamps, antiques, most coins)
• S-corporation stock

The collectibles prohibition is a common surprise. You can hold gold bullion in an SDIRA (if it meets 99.5% purity standards), but you cannot hold a rare coin collection, fine art, or wine. The IRS draws a clear line between investment-grade precious metals and collectible items.

Why Use an SDIRA for Alternative Investments

Tax Efficiency on High-Income Assets

Private credit generates interest income taxed at ordinary income rates — up to 37% federally. Inside a Traditional SDIRA, that income grows tax-deferred. Inside a Roth SDIRA, it's tax-free forever.

A $50,000 private credit allocation earning 10% generates $5,000 annually. In a taxable account at a 32% tax rate, you keep $3,400. In a Roth SDIRA, you keep $5,000. Over 20 years of compounding, that tax drag creates a six-figure difference.

Shelter Collectible Tax Rates

Gold and precious metals face a 28% maximum capital gains rate as "collectibles." Holding gold in an SDIRA eliminates this tax entirely (Roth) or defers it (Traditional). The tax savings alone can justify the SDIRA custodian fees for investors with meaningful precious metals positions.

Compound Alternative Returns Tax-Free

Many alternative investments have multi-year hold periods that align naturally with retirement accounts. Real estate held for 10+ years, private equity with 10-year lockups, startup investments with 5–10 year horizons — these long holding periods maximize the value of tax-deferred or tax-free compounding.

SDIRA Platforms Compared

Alto IRA

Alto IRA has become the most popular SDIRA platform for alternative investors, largely because of its integrations. Alto connects directly with platforms like Masterworks, AngelList, Republic, and dozens of other alternative investment platforms. This means you can invest through your existing platform accounts using Alto IRA funds — no manual paperwork or wire transfers.

Fees: Alto's Starter plan is free for basic crypto investments. The Pro plan costs $25/month (or $250/year) and enables investments in alternatives platforms, startups, and real estate. No asset-based fees, which is a significant advantage for larger accounts.

Minimum: No account minimum. Fund via rollover, transfer, or annual contributions.

Best for: Investors already using alternative investment platforms who want to route those investments through a tax-advantaged account. The platform integrations make Alto the path of least resistance.

Rocket Dollar

Rocket Dollar takes a different approach — it gives you a checkbook-controlled LLC inside your IRA. This means you can write checks, wire funds, and make investments directly without waiting for custodian approval on each transaction.

Fees: Silver plan at $15/month with a $360 one-time setup fee. Gold plan at $30/month with a $600 setup fee, including priority support and additional features. No asset-based fees.

Minimum: No account minimum after the setup fee.

Best for: Active investors who make frequent alternative investments and want speed and control. The checkbook LLC structure eliminates the multi-day processing delays that plague traditional SDIRA custodians. Real estate investors particularly benefit from the ability to close deals quickly.

Equity Trust

Equity Trust is one of the oldest and largest SDIRA custodians, with over $50 billion in assets under custody. The company has been in business since 1974 and offers the broadest range of supported asset types.

Fees: Tiered fee structure based on account value. Accounts under $250,000 pay $225–$395 annually. Transaction fees apply for each investment action ($10–$200 depending on type). The fee structure is more complex than Alto or Rocket Dollar.

Minimum: Varies by account type but generally $500 to open.

Best for: Investors with larger SDIRA balances who want an established, full-service custodian with extensive experience in complex alternative assets. Equity Trust's longevity and scale provide confidence for investors holding illiquid, hard-to-value assets in their retirement accounts.

Setting Up Your SDIRA: Step by Step

Step 1: Choose Traditional or Roth. Traditional SDIRAs offer tax-deferred growth — you contribute pre-tax dollars and pay taxes at withdrawal. Roth SDIRAs use after-tax dollars but grow tax-free. For high-returning alternatives, Roth is generally superior if you qualify (income limits: $161,000 single, $240,000 married in 2026).

Step 2: Open the account. Apply online with any of the platforms above. You'll provide standard identity verification and select your account type.

Step 3: Fund the account. Three options: contribute new money (up to $7,000/$8,000 annual limit), roll over funds from an existing 401(k) or IRA, or transfer from another IRA. Rollovers and transfers have no dollar limits and no tax consequences if executed properly.

Step 4: Make investments. Direct Alto to invest through a connected platform, write a check from your Rocket Dollar LLC, or submit an investment direction form to Equity Trust. Each platform handles this differently.

Step 5: Maintain compliance. All expenses related to SDIRA investments must be paid from the IRA — not from personal funds. All income flows back into the IRA. Violating this creates a "prohibited transaction" that can disqualify your entire IRA.

Critical SDIRA Rules You Must Follow

Prohibited Transactions

You cannot transact with "disqualified persons" — yourself, your spouse, children, parents, and certain business entities you control. Examples of violations:

• Buying a rental property from your IRA, then living in it
• Using personal funds to repair an SDIRA-owned property
• Lending SDIRA money to your business
• Hiring your son to manage an SDIRA-owned rental

Violations trigger immediate disqualification of the entire IRA, creating a taxable distribution plus a 10% penalty if you're under 59½.

UBTI: The Hidden Tax

Unrelated Business Taxable Income (UBTI) applies when your SDIRA earns income from an active trade or business or uses debt financing. If your SDIRA-owned rental property has a mortgage, the income attributable to the mortgaged portion generates UBTI, taxed at trust rates up to 37%.

UBTI exceeding $1,000 requires filing Form 990-T and paying taxes from the IRA. This doesn't disqualify the IRA, but it erodes the tax advantage. Debt-free investments avoid UBTI entirely.

Best Alternative Investments for an SDIRA

Private credit is the top candidate. High yields taxed as ordinary income become tax-free in a Roth SDIRA. Platforms like Percent and Yieldstreet work with Alto IRA.

Precious metals benefit from avoiding the 28% collectible tax rate. Gold and silver in a Roth SDIRA grow completely tax-free.

Startup equity through Republic or Wefunder can generate massive gains. Those gains in a Roth SDIRA? Tax-free. Peter Thiel famously grew a Roth IRA to over $5 billion through early startup investments.

Real estate works well for patient investors who buy without leverage (avoiding UBTI). Rental income and appreciation compound tax-free in a Roth or tax-deferred in a Traditional SDIRA.

Frequently Asked Questions

How much does a self-directed IRA cost?

Annual costs range from $180 (Alto Pro yearly) to $395+ (Equity Trust for larger accounts). Rocket Dollar runs $180–$360/year after setup. Compare these costs to the tax savings — even a few hundred dollars in annual fees is trivial compared to saving 25–37% in taxes on alternative investment income.

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

Yes. A direct rollover from a 401(k) to an SDIRA is tax-free and penalty-free. You can roll over any amount — there's no limit. Contact your 401(k) administrator to initiate the rollover, and provide your SDIRA custodian's information. The process typically takes 1–3 weeks.

Can I use a self-directed IRA to invest in real estate?

Yes, and real estate is one of the most popular SDIRA investments. Your IRA can buy residential or commercial property, collect rent, and sell for a profit — all tax-advantaged. The property must be for investment only (you can't live in it), and all expenses and income must flow through the IRA.

What happens if I make a prohibited transaction?

The IRS treats the entire IRA as distributed on January 1 of the violation year. You'll owe income tax on the full account value plus a 10% early withdrawal penalty if you're under 59½. A $200,000 SDIRA disqualified by a prohibited transaction could cost $70,000+ in taxes and penalties.

Is a Roth or Traditional SDIRA better for alternatives?

Roth is generally better for high-returning alternatives because all growth is tax-free. If you expect your alternative investments to generate strong returns, paying taxes now (Roth contributions) to avoid taxes on larger future gains is mathematically advantageous. Traditional SDIRAs are better if you need the current tax deduction.

Can I manage my SDIRA investments myself?

Yes — that's the "self-directed" part. You choose every investment. The custodian processes your directions but provides no advice. This freedom requires you to conduct your own due diligence. Most SDIRA custodians explicitly disclaim any responsibility for your investment decisions.
