When the One Big Beautiful Bill got signed, every outlet ran the same story. The estate tax exemption jumped to $15 million per person. $30 million for a couple. Permanent. No sunset. Big number. Big headline.
Buried underneath it, a second provision landed. This one didn't get a headline. It got a footnote. And that footnote now lets the IRS double-tax roughly $53,000 of every million dollars your trust sends to a beneficiary. Nothing on the tax return tells your accountant it happened.
The Pipe
Here's how trusts worked for decades. Think of a nongrantor trust (the kind where the trust itself pays taxes, not you) as a pipe. Money flows in one end. Money flows out the other end to the beneficiary. The IRS taxes it once. At the beneficiary's end.
The trust gets a full deduction for whatever it sends out. That deduction zeroes out the trust's tax bill on the distributed cash. The beneficiary picks up the income on their own return. One dollar. One tax. Simple plumbing.
This is the conduit principle. It kept the system honest.
The Drip
The old tax code had a sentence. Section 68(e). It said, basically, “This section shall not apply to any estate or trust.” That one sentence kept the pipe clean.
The new law rewrote Section 68. It dropped that sentence. No replacement. No explanation in the bill text.
Then, on May 28, 2026, the Joint Committee on Taxation released its Blue Book (their after-the-fact explanation of what Congress meant by the new law). Footnote 102 confirmed it:
The overall limitation on itemized deductions applies to trusts and estates, including with respect to the income distribution deduction.
Right. Read that again. “Including with respect to the income distribution deduction.” That's the pipe. That's the thing that kept trusts from being taxed twice. And the JCT just said the new haircut applies to it.
The haircut is 2/37ths. Roughly a nickel on every dollar your trust deducts for sending cash to a beneficiary.
While everyone was distracted by the SpaceX IPO, Elon Musk quietly started backing a NEW AI startup…
That has been called “the fastest-growing business in the history of capitalism.”
Even though this has nothing to do with robots, self-driving cars, and rockets…
It's growing faster than Tesla… faster than SpaceX… and even 23 times faster than Nvidia.
The Money
I mean, let's walk it. One step at a time.
A trust earns $1,000,000. The trust sends the full million to the beneficiary. Under the old rules, the trust deducts the full million. Tax bill at the trust level: zero. The beneficiary pays tax on the million. Done.
Now. The trust earns $1,000,000. The trust sends the full million. But the deduction gets cut. The trust can only deduct about $947,000. The other $53,000 sits on the trust's books as taxable income. At 37%, the trust owes roughly $19,600 on money it already sent out the door.
The beneficiary still reports the full $1,000,000 on their return. Still pays tax on all of it.
Two bites. Same dollar.
The Invisible Part
Pull up Form 1041. Look at line 18. It says “Income distribution deduction.” That's it. Just a label and a number. The number is smaller now. No asterisk. No box to check. No flag.
Your CPA sees a number. Not a haircut. The form doesn't whisper. It just pays less.
The Scale
Look, this isn't a billionaire problem. A nongrantor trust hits the 37% bracket at $16,000 of income. A single person doesn't hit it until $640,600. A married couple, $768,700.
If your family trust earns more than $16,000 a year, this touches you.
The Shrug
Was this on purpose? I dunno. Nobody's sure. The trust lawyers' group, the accountants' group, and the New York State Bar Association all asked Treasury and the IRS to fix it before the Blue Book even dropped. One group after the other. The language they used was polite. The speed was not.
And here's the thing. That Blue Book isn't even official legislative history. Courts have said so. It's the JCT's interpretation of what Congress meant. Whether Congress actually meant it is a different question.
“It is unclear, at least in some cases, to what extent revised Section 68 was intended to apply to itemized deductions that are only available to trusts and estates.”
That's the New York State Bar's tax section. Read it again. They're not saying it's wrong. They're saying nobody knows if it was supposed to happen.
The $15 million exemption was the show. Footnote 102 was the fine print.
The rules are the rules until someone changes them. Pull up your 1041.
