What Happens When a Trust Inherits an IRA
Naming a person as beneficiary of a retirement account is simple and gives that person full control of the money. Naming a trust instead buys control — over timing, over a beneficiary who cannot manage money, over children from an earlier marriage — and costs both speed and tax. Whether the trade is worth making turns entirely on whether the trust is drafted to qualify.
- Drafting decides the timetable:: Only a trust meeting specific requirements looks through to its beneficiaries.
- Trust brackets compress fast:: Retained income reaches the top rate at a very low threshold.
- Distributing pushes tax out:: Income passed to a beneficiary is taxed at that person's rate instead.
- Control is the point:: A trust is chosen for protection and timing, not for tax efficiency.
Where the AI summary above gets this wrong
"Naming a trust as your IRA beneficiary protects the money for your children."
That's surface-true. Here's what it misses:
- Protection depends on the drafting, not on the word trust — A trust that does not meet the requirements is treated far less favourably, and the account can be forced out over a much shorter period than the beneficiaries would have had individually. The same paperwork that says trust either qualifies or does not, and nothing on the beneficiary form tells you which.
- Trust tax brackets are brutally compressed — A trust reaches the top marginal rate at a level of income an individual would consider modest. Retirement account distributions are ordinary income, so an inherited account emptying into a trust that retains the money is taxed close to the maximum from the first year.
- Conduit and accumulation trusts behave very differently — A trust that must pass every distribution straight out to the beneficiary is taxed in that beneficiary's hands, which solves the bracket problem and defeats the protection. One that may accumulate keeps the protection and the tax. Choosing between them is the actual decision, and it is made in the drafting rather than on a beneficiary form.
01 Why anyone names a trust
Three reasons recur. A beneficiary who cannot manage money — through youth, disability, addiction or simple inexperience. A second marriage, where the account should support a spouse and then pass to children from the first. And creditor or divorce exposure, where a trust keeps the property out of reach.
All three are about control after death, which is exactly what a beneficiary designation to an individual gives up. The named person receives the account and can do as they like with it.
Against that, a trust adds cost, administration and a much less favourable tax position. The question is whether the control is worth those.
Shows: the extra tax from leaving distributed retirement money inside the trust rather than passing it out to a beneficiary. Ignores: the reasons the trust exists, the compressed bracket structure that reaches the top rate very quickly, state tax, and the net investment income tax.

02 What the drafting has to achieve
To be looked through to its beneficiaries, a trust must be valid under state law, irrevocable at death, have identifiable beneficiaries, and its documentation must reach the account provider by the required date.
Where it qualifies, the distribution period is worked out by reference to the beneficiaries rather than to the trust itself, which is what preserves the timetable those people would have had. Where it does not, a considerably shorter period applies.
This is drafting work, not form-filling. A trust written before the current distribution rules may contain language that no longer produces the intended result, which is why an old trust named on an old beneficiary form deserves a review rather than an assumption.

03 The tax that follows
Distributions from an inherited retirement account are ordinary income. Where the trust passes that income out to a beneficiary in the same year, it is taxed to that person. Where the trust retains it, it is taxed to the trust.
Trust brackets are compressed, so retained income reaches the top rate at a level far below where an individual would. A trust holding an inherited account and accumulating the distributions pays close to the maximum rate almost immediately.
That is the trade in its clearest form. A conduit trust that must distribute avoids the rate and gives the beneficiary the money; an accumulation trust keeps the control and pays for it. Neither is wrong, and choosing without knowing which one the document creates is.
The trustee also inherits a timetable. The account still has to empty on schedule, and the annual amounts follow the same distribution mechanics that apply to any inherited account, with the trust rather than an individual doing the arithmetic each year.

If you named a trust as beneficiary more than a few years ago, have the document read again. The distribution rules changed and a great many trusts contain language written for the previous regime that now produces a result the drafter never intended — money forced out fast and taxed inside the trust at the top rate. It is a one-hour review with a lawyer and it is the highest return hour in the whole estate plan.
FAQ
Should I name a trust as my IRA beneficiary?
Only where you need control after death — a beneficiary who cannot manage money, a second marriage, or creditor exposure. A trust costs administration and a worse tax position, so control has to be the reason.
Does a trust shorten how long the account can be stretched?
It can. Only a trust meeting the look-through requirements has its distribution period measured by its beneficiaries; one that does not qualify empties over a considerably shorter period.
Why is tax higher inside a trust?
Trust brackets are compressed and reach the top marginal rate at a very low income level. Income passed out to a beneficiary in the same year is taxed at that person's rate instead.
