The ERISA 25% Rule Explained

The ERISA 25% Rule Explained: What Every Real Estate Syndicator Needs to Know About Raising IRA Capital

If you’re raising capital for real estate deals, you’ve probably noticed a growing trend:

More and more investors want to use their retirement accounts.

Self-Directed IRAs and Solo 401(k)s have opened the door for everyday investors to deploy retirement capital into real estate, syndications, and private deals. That’s a massive opportunity for sponsors.

But there’s one rule that quietly shapes how these deals are structured:

The ERISA 25% Rule.

If you’re not aware of it or not tracking it correctly, it can create serious compliance issues.

Let’s break it down in plain English.

Why This Matters to You as a Syndicator

Retirement capital is one of the fastest-growing sources of equity in private real estate.

But when you accept funds from IRAs or other retirement plans, you are not just bringing in capital. You are potentially triggering ERISA regulations that can change how your entire deal is treated.

That’s where the 25% Rule comes in.

What Is the ERISA 25% Rule?

At a high level, the rule determines whether your deal becomes subject to ERISA “plan asset” rules.

Here’s the simple version:

• If less than 25% of your equity comes from retirement accounts, you’re generally in the clear
• If 25% or more comes from retirement accounts, your deal may be treated as holding “plan assets”

If that happens:

• You could be considered an ERISA fiduciary
• Your deal becomes subject to additional rules and restrictions
• You take on a higher level of legal and compliance responsibility

That’s why most sponsors are very intentional about staying below that threshold.

Who Counts as a “Retirement Investor”?

This is where a lot of people get tripped up.

It’s not just pension funds.

The following typically count as “Benefit Plan Investors”:

• Self-Directed IRAs
• Solo 401(k)s
• Employer-sponsored retirement plans
• Certain entities holding retirement money

So yes, your IRA investors count toward that 25% cap.

How the 25% Rule Actually Works

The rule is calculated based on ownership percentage, usually tied to capital commitments.

Example:

• $8M from cash investors
• $2M from retirement accounts

That puts you at 20% retirement capital, which is compliant.

But if retirement capital increases to $3M:

• You are now at 30%
• You may have crossed into ERISA territory

This is why sponsors actively track this number throughout the raise, not just at the beginning.

How Smart Sponsors Stay Compliant

In the real world, this is less about theory and more about process.

Most experienced operators:

• Track investor type during the subscription process
• Maintain a running percentage of retirement capital
• Recalculate at key milestones like final close or new investor admissions
• Build in a buffer, often targeting 20% to 24%

Many also include language in their operating agreements allowing them to:

• Reject subscriptions
• Adjust allocations
• Stay below the threshold if needed

This is standard practice in well-run syndications.

When the 25% Rule Does Not Apply

Here’s where it gets interesting.

There is an exception if your deal qualifies as an Operating Company.

For real estate, that typically means a Real Estate Operating Company (REOC).

To qualify, the deal must:

• Have at least 50% of its assets in real estate
• Be actively involved in managing or developing those properties

If you meet those requirements:

• The underlying assets are not treated as plan assets
• The 25% limitation may not apply

Sounds great, right?

Not so fast.

Why Most Syndicators Still Follow the 25% Rule Anyway

Even though the REOC exemption exists, many sponsors choose not to rely on it.

Why?

• It requires ongoing operational activity
• Passive deals may not qualify
• It can be fact-specific and legally complex
• It often requires ongoing legal oversight

For most sponsors, it is simply easier and safer to:

Stay under 25% and avoid the issue entirely.

What This Means for Investors Using IRAs

If you’re investing through a Self-Directed IRA, here’s the key takeaway:

You are not responsible for tracking the 25% rule. The sponsor is.

However, understanding it helps you:

• See why some deals limit IRA investors
• Understand why you might get turned away from a deal
• Better evaluate how sponsors structure their raises

It also reinforces something important:

Retirement capital is in demand, but it comes with rules.

Final Thoughts

The 25% Rule is not something to fear, but it is something to respect.

If you are raising capital:

• Track it
• Understand it
• Build systems around it

If you are investing:

• Know that these limits exist
• Work with sponsors who understand compliance

Make sure you consult a qualified syndication attorney to get to the fine-points of raising capital.

At the end of the day, retirement capital is one of the most powerful tools in real estate investing. But like anything in this business, the investors who win long term are the ones who understand both the opportunity and the rules that come with it.
