Buy, Borrow, Die: What I Learned About Trusts Before Setting One Up for My Kids

A 30-second Instagram reel sent me down a rabbit hole. Half of it was right, and the wrong half is the expensive part.

The viral "put it in a trust and borrow against it" strategy is real — but the trust step is where most people get it backwards. Here's the fork in the road, the Washington problem nobody mentions, and what I'm actually planning for my family.

TRUST

A reel came across my feed the other night. Nice house, nice sky, and nine lines of text over the top of it:

Dad buys stock at $250K. It grows to $12M. If he sells, he owes tax on an $11.75M gain. Instead, he puts it in a trust. Borrows against it. Borrowing is not income. So no tax. He lives on loans. Never sells. He dies holding the asset. Kids inherit at a $12M basis. IRS gets $0.

Looking at the reel like that gave me an idea of how to save money on taxes from my investments, and how I can give these assets to my children.

So I went and read the actual rules. And here’s the thing — most of it is true. It’s a real strategy with a real name. But one of those nine lines is doing something completely different from what it says it’s doing, and if you follow it wrong, you get the exact opposite of what the reel promises.

No hype, just math. Let’s go through it.

The strategy is real. It’s called “Buy, Borrow, Die.”

That’s not a nickname I invented — it’s what tax academics actually call it. Three of the four steps in that reel are straightforward and correct:

Buy and never sell. In the U.S., you’re taxed on realized gains. No sale, no realization, no tax bill. You can watch a position go from $250K to $12M and owe the IRS exactly nothing along the way, forever, as long as you don’t hit the sell button.

Borrow against it. Loan proceeds are not income. This is the least controversial rule in the entire tax code — if you take out a mortgage, nobody thinks you earned $500,000 that year. Same logic applies when the collateral is a stock portfolio instead of a house. The product exists: banks and brokerages call it a securities-backed line of credit, or a pledged asset line.

Heirs inherit at the death-date value. This is the step-up in basis, and it’s the part that makes the whole thing work. Under IRC §1014, when you die, the cost basis of your assets resets to fair market value on your date of death. Your $250K basis becomes $12M. Your kids sell the next morning and their taxable gain is roughly zero. The $11.75M of appreciation you built over 30 years is never taxed as income. Not deferred — erased.

That’s three for three. So where does it break?

The line that’s wrong: “he puts it in a trust”

Here’s what took me the longest to understand, and it’s the single most important thing in this article:

The step-up in basis has nothing to do with a trust. It comes from the asset being inside your taxable estate when you die. A trust doesn’t create the step-up — and the wrong kind of trust destroys it.

In March 2023 the IRS issued Revenue Ruling 2023-2, which settled an argument a lot of people had been quietly hoping would go the other way. It confirmed that assets held in an irrevocable grantor trust that are not included in the grantor’s gross estate do not get a basis adjustment at death.

Read that again with the reel in mind. The whole reason people are told to use an irrevocable trust is to move assets out of their estate — that’s how you dodge estate tax. But moving them out of your estate is exactly what disqualifies them from the step-up.

So the fork looks like this:

Revocable living trust. Assets stay in your estate. You keep full control, you can change or unwind it any time. Step-up in basis: preserved. Estate tax savings: none — it does nothing for income tax at all. What it actually buys you is probate avoidance, privacy, and a clean handoff. Those are real, valuable things. They’re just not tax things.

Irrevocable trust that removes assets from your estate. Estate tax exposure: reduced. Step-up in basis: gone. Your kids inherit with your original $250K basis — the precise outcome the reel says you’re avoiding.

You don’t get both. That’s the trade, and no thirty-second video is going to tell you about it.

(There are structures — like retaining certain powers so assets are pulled back into the estate on purpose — where sophisticated planners deliberately choose to keep assets includable because the step-up is worth more than the estate tax savings. That decision requires someone with credentials looking at your actual balance sheet. It’s above my pay grade and probably yours.)

The illustrative math, at normal-family scale

Let me shrink the reel’s numbers to something that looks more like an actual household. These are illustrative — round numbers to show the mechanism, not a projection of anything.

Say you put $100,000 into an index fund and thirty years later it’s worth $1,000,000. Your unrealized gain is $900,000.

If you sell it yourself, in Washington:

  • Federal long-term capital gains at 20%: about $180,000
  • Net investment income tax at 3.8%: about $34,000
  • Washington capital gains excise tax at 7% (after the standard deduction, roughly $278,000 for 2025 and indexed): about $43,000

Call it around $257,000 gone. Over a quarter of the position.

If you never sell and it’s in your estate when you die: basis steps up to $1,000,000. Your kids sell. Taxable gain: approximately zero. That $257,000 stays in the family.

If you moved it to an irrevocable trust outside your estate: basis stays $100,000. Your kids sell and eat the full $900,000 gain themselves.

Same asset, same $1M, three completely different outcomes based on a structuring decision made decades earlier. That’s what got my attention.

Living in Washington changes this a lot

This is the part I didn’t expect, and it’s the part that actually pushed me from “interesting” to “I need to deal with this.”

The federal estate tax exemption for 2026 is $15 million per person — raised and made permanent by the One Big Beautiful Bill Act. At that level, the federal estate tax is a non-issue for the overwhelming majority of families. The reel’s $12M estate wouldn’t owe a dollar of federal estate tax.

Washington is a different story. Our state exemption is $3 million per person — more than $12 million below the federal line. And Washington has no portability, which means a married couple that doesn’t do specific planning simply loses the first spouse’s entire $3M exemption when they die. It doesn’t transfer.

A $12M estate here is looking at roughly $9M of exposure. “The IRS gets $0” and “the family pays $0” are not the same sentence in this state.

One important caveat on timing: Washington’s estate tax is mid-change right now. The top rate was raised to 35% effective July 2025, then rolled back to 20% for deaths on or after July 1, 2026. Sources also disagree on whether the $3M exemption stays indexed to inflation going forward — some read the rollback bill as freezing it. I could not verify that piece confidently, so I’m flagging it as unsettled rather than stating it. Anything you read about Washington estate tax written before spring 2026 may be describing a rate schedule that no longer applies. Verify current figures with the Washington DOR before making any decision on this.

And separately from the estate tax: Washington’s capital gains excise tax is 7% on long-term gains above the annual deduction, with an additional 2.9% on gains above $1 million — a 9.9% top rate. Real estate and retirement accounts are exempt. Stock isn’t.

So for a Seattle-area family, the case for doing something deliberate kicks in at a much lower net worth than the national conversation suggests. That was my real takeaway.

The borrow leg — where my own thinking was fuzzy

When I first worked through this, my reaction to the borrowing step was: it’s borrowing against my own assets that are in the trust, so I’m not losing money. And if there’s interest, that’s building my assets too.

Half of that is exactly right, and figuring out which half was useful.

The right half: you keep the asset. That’s the entire point. If you sell $200,000 of stock to fund something, that $200,000 stops compounding forever. If you borrow $200,000 against it instead, the full position stays invested and keeps growing. You’ve converted a permanent withdrawal into a temporary liability. That’s a genuinely different financial outcome and it’s why wealthy families do this.

The half I had backwards: it depends entirely on who you’re borrowing from.

  • Borrowing from a bank against pledged trust assets — a securities-backed line of credit. The interest goes to the lender. It is a real, permanent cost, and it does not build anything of yours. On top of that, personal-consumption interest generally isn’t deductible; the investment interest deduction is limited and requires the borrowing to be traceable to investment use. Fund a vacation with it and you’re paying full freight.
  • Borrowing from the trust itself — the trust holds cash or assets and lends to you or a beneficiary at a proper interest rate, with a real note. Here my instinct is correct: the interest flows back into the trust, growing the corpus for the beneficiaries. It’s genuinely a different transaction.

Those are two completely different things that both get described as “borrowing against the trust,” and I was blending them.

And the risk nobody puts in the reel: a securities-backed line is collateralized. If the underlying position drops far enough, the lender can demand you post more collateral or liquidate — and they can do it at the worst possible moment. If you happen to be sitting on a concentrated position in one high-volatility name, the leg of this strategy that looks the safest is the one most likely to hurt you. Nobody gets margin-called at the top.

What I’m actually planning

So here’s where I’ve landed, and I want to be honest that it’s a direction rather than a decision.

Right now I’m working out which is the right structure — revocable or irrevocable. After I do more research, I’ll decide within a year.

And this isn’t just about my kids. It’s also about building up my assets and being able to use them when I need money during my own life. That reframed the whole question for me. A pure estate-tax structure optimizes for what happens after I’m gone. What I want is something that works while I’m alive too — that I can access, adjust, and use, without shipping the assets somewhere I can never reach them again.

Which, when you frame it that way, points hard in one direction — a revocable structure keeps flexibility and control, and it preserves the step-up. What it doesn’t do is anything about Washington’s $3M line. That’s the tension I have to resolve, and I don’t think I resolve it by reading more blog posts. That’s a conversation with an actual estate attorney licensed in Washington.

I’ll write up what that conversation costs and what they tell me. That’s more useful to you than another article about a reel.

What I got wrong

I knew trusts existed. I thought they were something only rich people did — a thing you set up after you’d already made it, with a lawyer in a wood-paneled office.

That was wrong, and it’s the assumption I most want to knock down here. If you own assets, a trust is potentially for you. A house in the Seattle area plus a retirement account plus a brokerage balance gets a normal family uncomfortably close to Washington’s $3M line faster than most people expect — and probate avoidance alone is worth the conversation even well below it.

The other thing I got wrong: I assumed “trust” was a single product. It isn’t. It’s a category, and the choice inside that category determines whether your kids inherit with a stepped-up basis or your original one. Getting that backwards is a six-figure mistake made quietly, decades before anyone notices.

The reel ends with “Follow the plan.” I’d put it differently: understand the plan well enough to know which version of it you’re actually following.
