What Shouldn’t You Put in a Trust?

Executive Summary

Trusts are powerful estate planning tools—but loading every asset into one is a common and costly mistake. What shouldn’t you put in a trust? At a minimum: IRAs and other tax-deferred retirement accounts, which cannot legally be owned by a trust without triggering serious tax consequences. Beyond that, assets with existing beneficiary designations—like life insurance and payable-on-death bank accounts—often transfer more efficiently and affordably outside a trust entirely. This article walks through the key assets to keep out of your trust, and why simpler tools sometimes win.

What Is a Trust, and Why Does Asset Selection Matter?

A revocable living trust is a legal arrangement that holds assets on your behalf during your lifetime and distributes them to your beneficiaries after you die—outside of probate. But not every asset belongs in one. Placing the wrong assets into a trust can trigger taxes, complicate administration, or create legal headaches that the trust was designed to avoid in the first place.

Trust planning is one of the most powerful strategies in estate planning—right up there with proper beneficiary designations and asset titling. When done correctly, a revocable living trust can help your heirs avoid probate, maintain privacy, and receive assets efficiently. When done carelessly, it can cost far more than it saves.

The question isn’t just what should you put in a trust—it’s equally important to ask what shouldn’t you put in a trust. Some assets are legally ineligible. Others are simply more efficiently handled another way. And a few can create real financial harm if titled incorrectly.

Can an IRA Be Owned by a Trust? Why Retirement Accounts Don’t Belong There

No. An IRA cannot be owned by a trust. IRAs—along with 401(k)s, 403(b)s, and other tax-deferred retirement accounts—are individual accounts by legal definition. They must be held in the name of a living person, not an entity like a trust.

Picture this, an investor retitles their IRA into their trust, believing they’re being thorough. In reality, the IRS treats that transfer as a full distribution. The entire account balance becomes taxable income in the year of the transfer—a potentially devastating and irreversible mistake.

Retirement accounts—including traditional IRAs, Roth IRAs, SEP-IRAs, and employer-sponsored plans—pass to heirs through beneficiary designations, not through your will or trust. That single form you fill out when you open the account can override everything else in your estate plan. There are some nuanced situations where naming a trust as the beneficiary (not the owner) of a retirement account may make sense.

Key Takeaway: Don’t retitle an IRA into your trust’s name. Instead, review your beneficiary designations regularly—especially after major life events like marriage, divorce, or the birth of a child.

When Do POD and TOD Designations Outperform a Trust?

Payable-on-death (POD) and transfer-on-death (TOD) designations allow assets to pass directly to a named individual at your death—bypassing probate just as effectively as a trust, but without the administrative cost or complexity.

Let’s be direct: trusts are not always the right tool. They cost money to draft, require proper funding to work, and need ongoing maintenance as your life changes. For certain assets and certain families, a well-placed beneficiary designation accomplishes the same goal with far less friction.

Bank accounts, savings accounts, and even standard brokerage accounts can often carry POD or TOD designations in Missouri. Your bank or brokerage holds the account in your name during your lifetime. When you die, the named beneficiary presents a death certificate and takes ownership directly—no probate, no trust administration, no delay.

For straightforward situations—a single beneficiary, a financially capable adult, no blended family complexity—this works beautifully. Consider:

• A checking account with a single adult child named as POD beneficiary
• A brokerage account with a TOD designation to a healthy, competent spouse
• A life insurance policy with a named primary and contingent beneficiary

In each case, a trust adds cost and complexity without meaningfully improving the outcome. The simplest structure that achieves your goals may be the best structure.

That said, POD and TOD designations have real limitations. They don’t offer control over how assets are spent. They can create conflict if multiple heirs are involved. They offer no protection for a beneficiary who is a minor, has a disability, or struggles with financial management. And if a named beneficiary predeceases you and you haven’t updated the form, assets may go somewhere unintended—or fall into your estate and face probate anyway.

The takeaway is not that trusts are bad—it’s that they’re tools. Like any tool, the value depends on whether the job actually requires it.

What Other Assets Typically Shouldn’t Go Into a Trust?

Beyond retirement accounts, several other asset types are either legally ineligible, operationally impractical, or better handled through other transfer mechanisms outside a trust.

Life Insurance Policies

The policy itself doesn’t belong in your revocable living trust. Life insurance passes by beneficiary designation. If your beneficiaries are clearly named—and you update them as life changes—the death benefit flows directly to them, income-tax-free, with no probate and no trust required.

The exception: some clients create an irrevocable life insurance trust (ILIT) to remove the death benefit from their taxable estate. But that’s a separate, specialized strategy—not something you accomplish by simply transferring a policy into your living trust.

Health Savings Accounts (HSAs)

Like IRAs, HSAs are individual accounts and cannot be owned by a trust. They pass by beneficiary designation. A surviving spouse can inherit an HSA intact; other beneficiaries receive it as taxable income. Name your beneficiaries carefully—and keep them updated.

Active Business Interests (In Some Cases)

Depending on the business entity type and your operating agreement, transferring a business interest into a trust can trigger consent requirements, alter management rights, or create complications with co-owners. Business succession planning often involves separate strategies—buy-sell agreements, family LLCs, or business-specific trusts. Always coordinate with legal counsel before changing business ownership structure.

Vehicles

Retitling a car into a trust name can create headaches with insurance coverage, registration, and DMV paperwork. Most financial planners and attorneys suggest leaving everyday vehicles out of a trust unless the estate is large enough that probate avoidance justifies the administrative friction. Missouri does offer a transfer-on-death title option for vehicles, which accomplishes the same goal simply.

Assets With Small Value

Missouri’s simplified probate process handles smaller estates relatively efficiently. Not every asset warrants the administrative overhead of trust ownership. Be intentional about what you fund in—and why.

How Do You Decide What Actually Belongs in Your Trust?

The right answer depends on your specific assets, family structure, state laws, and goals. A good framework: fund your trust with assets that would otherwise face probate and aren’t better handled by a beneficiary designation. Real estate is the clearest example.

Real property—your home, rental properties, vacation homes—is often the primary reason people establish a revocable living trust in the first place. Without a trust, real estate must pass through probate (however, some states have TOD for real estate), can take months and become a matter of public record. A properly funded trust avoids all of that.

Beyond real estate, taxable brokerage accounts, bank accounts without POD designations, and business interests (where appropriate) are common candidates for trust funding. The key is making sure the trust is actually funded—meaning assets are retitled into the trust’s name during your lifetime. An unfunded trust does nothing.

Estate planning is not a one-time event. Major life changes—divorce, a new child or grandchild, the death of a named beneficiary, a significant inheritance, moving to a new state—all warrant a review of your trust documents, beneficiary designations, and asset titling. The families who benefit most from their estate plans are the ones who treat it as an ongoing conversation, not a document that sits in a drawer.

Frequently Asked Questions: What Shouldn’t You Put in a Trust?

What assets are not allowed in a trust?

Certain assets are legally ineligible to be owned by a trust. These include IRAs, 401(k)s, 403(b)s, and other tax-deferred retirement accounts, which are defined as individual accounts under IRS rules. Health savings accounts (HSAs) fall into the same category. Attempting to retitle these accounts into a trust’s name is treated as a full taxable distribution—a serious and often irreversible financial mistake.

Can you put an IRA in a living trust?

No—you cannot retitle an IRA into a living trust’s name without triggering a taxable distribution. An IRA must be held by a living individual. However, there are situations where naming a properly structured trust as the beneficiary of an IRA may make sense—particularly for minor beneficiaries, special-needs heirs, or spendthrift situations. This is a nuanced strategy that requires coordination between a financial planner and an estate planning attorney, especially given the distribution rule changes introduced by the SECURE Act.

Is a POD or TOD designation better than putting an account in a trust?

For many straightforward situations, yes. A payable-on-death (POD) or transfer-on-death (TOD) designation achieves probate avoidance without the cost or administrative burden of trust funding. The designation tells your financial institution exactly who receives the account when you die—quickly and directly. The downside is control: POD and TOD designations don’t allow you to specify conditions, protect a financially vulnerable beneficiary, or plan for contingencies. When your situation is simple and your beneficiaries are capable adults, these designations are often the most efficient choice.

What happens if you put the wrong assets in a trust?

The consequences range from inconvenient to costly. Retitling an IRA into a trust triggers a full taxable distribution—potentially a massive, unexpected tax bill. Putting a vehicle in a trust can create insurance complications. Transferring a business interest without reviewing the operating agreement can alter management rights or trigger co-owner consent clauses. At a minimum, incorrect trust funding wastes administrative effort. At worst, it generates significant financial and legal harm.

Do I need a trust if I already have beneficiary designations on everything?

It depends on your full picture. If all of your meaningful assets already carry beneficiary designations—retirement accounts, life insurance, POD bank accounts, TOD brokerage accounts—and you own no real estate (or own it jointly with right of survivorship), a revocable living trust may offer limited additional benefit. That said, trusts provide advantages that designations don’t: the ability to control distributions over time, protect heirs with special needs or financial vulnerabilities, and plan for incapacity. The best approach is to map out your assets and run through what happens to each one under your current plan—that exercise often reveals gaps worth addressing.

Should my house be in a trust?

For most homeowners, real estate is the single strongest candidate for trust ownership. Without a trust, your home may have to pass through probate—a public, court-supervised process that can take months and involves legal fees. A funded revocable living trust transfers your home to your heirs privately and efficiently.

How often should I review what’s in my trust?

At a minimum, review your trust and all beneficiary designations every three to five years—or after any major life event. Marriage, divorce, the birth of a grandchild, the death of a named beneficiary, a significant change in net worth, or a move to a different state are all triggers for an immediate review. An estate plan that isn’t kept current can create exactly the problems it was designed to prevent.
