When you pass away, the money in your IRA or 401(k) doesn’t go through your will — it goes to whoever you named as the beneficiary. For many families, that works just fine. The money passes quickly and directly to their children or loved ones.
But what if that speed is exactly what worries you?
What if you’re concerned your children might withdraw too much too fast, trigger a large tax bill, or make poor financial decisions with the money you spent a lifetime saving?
That’s where something called a “see-through” trust can play a role in your estate plan.
Why beneficiary designations aren’t always enough
Naming a beneficiary on an IRA is simple. It avoids probate and gives your heirs direct access to the money. But that also means they can take out as much as they want, whenever they want.
Under today’s tax laws, most non-spouse beneficiaries must empty an inherited IRA within 10 years of the original owner’s death. That creates a serious tax planning challenge. If your child pulls out the entire account in one year, that distribution is added on top of their regular income and can push them into much higher tax brackets.
And taxes aren’t the only concern.
Once your child receives IRA money directly, it becomes their asset. It can be exposed to creditors, divorce settlements, lawsuits, and poor financial decisions.
What is a see-through trust?
A see-through trust (also called a look-through trust) is a special type of trust designed to receive IRA money while still allowing the IRS to “see through” the trust to the individual beneficiaries for tax purposes.
In simple terms, the trust controls the money — but the tax rules still apply based on who the beneficiaries are.
That gives you something most IRA beneficiary designations do not: control.
When a see-through trust makes sense
We don’t recommend these trusts for everyone. In fact, for most families, naming children directly is still the simplest and best solution.
But a see-through trust can make sense if you have concerns such as:
- A child who is financially irresponsible
- A child with substance abuse or spending issues
- A child in a shaky marriage
- A blended family with step-children
- Minor grandchildren
- A beneficiary who could face lawsuits or creditors
- A desire to control how and when money is distributed
In these situations, the trust can act as a guardrail, helping protect both the money and the person receiving it.
Why these trusts must be done correctly
Not all trusts can receive IRA money properly. To qualify as a see-through trust, four strict IRS rules must be met:
- The trust must be valid under state law
- It must be irrevocable (or become irrevocable at death)
- All beneficiaries must be identifiable people
- A copy of the trust must be given to the IRA custodian by October 31 of the year after death
If any of these rules are missed, the IRA could lose its favorable tax treatment — leading to higher taxes and fewer options for your family.
That’s why experience matters. These rules changed significantly under the SECURE Act and SECURE Act 2.0, and older trusts often no longer work the way people think they do.
The tax side matters just as much as the legal side
Trusts and IRAs are both tax-driven tools. If they are not coordinated properly, they can accidentally create large tax bills.
For example, trust tax brackets reach the top 37% rate very quickly — much faster than individual tax brackets. That means poorly designed trusts can cause more of your IRA to go to taxes instead of to your family.
This is why we look at the entire financial plan — not just the trust document.
Sometimes simpler is better
If your children are financially stable and you have no concerns about how they’ll handle the money, naming them directly as beneficiaries is often the best choice.
Trusts are powerful tools — but only when they’re used for the right reasons.
The bottom line
A see-through trust is not about avoiding probate. It’s about control, protection, and tax efficiency when your situation calls for it.
