I'm turning 50 this year. My child is three. When he is 60, I'm not going to be here — that's just math. When his kids are 60, his kids' kids will be old enough to have kids of their own. The timeline I'm trying to plan for isn't the next IPO or the next board seat. It's 100 years. And once you start thinking on that horizon, the tools you use to move wealth stop looking like financial products and start looking like infrastructure.
Two of those tools come up over and over in the conversations I have with my own estate attorney and with founders I advise: the QPRT and the dynasty trust. The QPRT is for the house. The dynasty trust is for everything else. Both are legal. Both have been around since the 1990s. Both are standard operating procedure for families with real wealth — and both are almost entirely invisible to people whose financial literacy ended at "max out your 401(k)."
The QPRT (Your House, But Not Really)
QPRT stands for Qualified Personal Residence Trust. The mechanic is simple and almost counterintuitive.
You put your house into an irrevocable trust. You name a term — let's say 10 or 15 years. During the term, you continue to live in the house, pay the maintenance, cover the taxes, treat it like your house. At the end of the term, legal title passes to your children (or whatever beneficiaries you named). If you want to keep living there after the term ends, you pay your kids fair market rent.
Here's the tax magic. When you put the house into the QPRT, the IRS values the gift using a formula that subtracts the value of your "retained interest" (the years you get to keep living there) from the value of the house. That retained interest can be worth a lot — 40%, 50%, 60% of the total value depending on the term length and interest rates. So a $2 million house going into a 15-year QPRT might be valued as a gift of only $1 million for gift tax purposes. You use $1 million of your lifetime gift exemption instead of $2 million.
And then here's the part that really matters. Whatever the house is worth at the end of the term — even if it has doubled — passes to your heirs at that $1 million gifted value. The appreciation during the term is out of your estate entirely. Ten years of appreciation on a $2 million house in any major metro area is frequently another million or two. All of it passes tax-free.
The Catch: You Can't Die During The Term
The one risk is mortality. If you die before the term ends, the house is pulled back into your estate as if the QPRT never existed. The entire strategy unwinds. This is why the term length is so important. For a healthy 50-year-old, a 15- or 20-year term is aggressive but reasonable. For a 70-year-old, you probably shorten the term or use a different tool entirely. Your attorney and your actuarial reality both get a vote.
Paying Rent To Your Own Kids Sounds Weird
I know. But think about it from the math. If you're paying rent to a trust that benefits your children, you're moving additional money out of your estate on top of the house itself — without using any gift tax exemption because rent isn't a gift. Every rent check becomes an additional legal wealth transfer. Over a ten or twenty year post-term period, that can add up to millions of additional dollars moved to the next generation without gift tax.
The families who understand this treat the QPRT as a two-phase strategy. Phase one: appreciation during the term passes tax-free. Phase two: rental payments post-term move additional cash out of the estate without using exemption. Both phases matter. Only using phase one leaves real dollars on the table.
A QPRT is the only legal tool I know of where you can give your house away, keep living in it, and end up with more money moved to your heirs than the house was ever worth.
The Dynasty Trust (100-Year Thinking)
Now we shift from the house to everything else. A dynasty trust is an irrevocable trust designed to hold assets for multiple generations — sometimes hundreds of years — without triggering estate tax or generation-skipping transfer tax at each generational handoff.
Normally, when wealth passes from you to your kids, there's an estate tax. When it passes from your kids to your grandkids, there's another estate tax. Three generations, three tax events, each potentially taking 40% off the top. Over three generations at 40% per handoff, a dollar becomes 21.6 cents. The tax code is designed to break up dynasties.
A dynasty trust blocks that. Assets go into the trust once. You use your lifetime gift and GST exemption to fund it. Once it's funded, the trust owns the assets. The trust can make distributions to beneficiaries — your kids, your grandkids, your great-grandkids — but the assets themselves never leave the trust and never get re-taxed at each generation. A dollar in the trust stays a dollar (plus growth) for as long as the trust exists.
How Long Can A Dynasty Trust Last?
This is where state selection matters. Under traditional common law, trusts were limited by the "rule against perpetuities" — roughly, a trust had to terminate within 21 years after the death of someone alive when the trust was created. About 90 to 100 years, in practice. A few states have abolished or dramatically extended the rule:
- South Dakota — no rule against perpetuities, trusts can last forever, no state income tax, strong asset protection
- Nevada — 365-year perpetuities period, no state income tax, strong privacy protections
- Delaware — 110 years for real property, indefinite for personal property, well-developed trust case law
- Alaska — no rule against perpetuities, strong self-settled asset protection
If you live in California or New York, you can still create a dynasty trust governed by South Dakota or Nevada law by using a trust company in that state. This is common. The trust lives in the state with the better rules; you live in whatever state you live in. The tax and legal treatment follows the trust's situs, not your residence.
Why This Matters For Mid-Range Wealth Too
I want to push back on the idea that dynasty trusts are only for billionaires. Run the math. If you put $5 million into a dynasty trust today and it grows at 7% for 100 years, that's over $800 million. Tax-free across generations. Even a $1 million dynasty trust at 7% for 100 years is $150 million. These are not numbers for the Walton family — these are numbers for a founder who has had one decent exit and thinks beyond their own lifetime.
The limit is the gift and GST exemption. In 2026, the federal exemption is around $13.6 million per person. You can fund a dynasty trust up to that amount without triggering current tax. If the exemption drops in future years (it is scheduled to roughly halve in 2026 absent Congressional action), getting the funding done before the cut becomes urgent. Families who fund at today's exemption lock in that amount even if the rules change later.
The "Irrevocable" Problem
The thing that stops most people from using a QPRT or a dynasty trust isn't the math. It's the word "irrevocable." Giving away assets you can't get back feels wrong. It feels like losing control. I've had this conversation with founders and the emotional resistance is real — it doesn't matter how good the numbers are if the founder can't mentally let go of the asset.
Here's the reframe. Irrevocable doesn't mean powerless. Trusts can be drafted with independent trustees, distribution committees, and trust protectors who have the power to adjust the trust over time. You can name yourself as a beneficiary in some cases (via a self-settled asset protection trust in Nevada, South Dakota, or Alaska). You can change beneficiaries through the trust protector. "Irrevocable" is a legal term, not a prison sentence.
That said, if you can't emotionally hand the asset over, don't do it. Estate planning tools only work if you're willing to actually use them. A trust on paper that you ignore because you wanted the asset back is worse than never setting it up.
What I'm Doing Myself
I'll be honest — I'm in the middle of updating my own estate plan. The 2006 trust my wife and I set up back when we were younger and childless needs to reflect the world we actually live in now: a 3-year-old toddler, Korean cultural values around family wealth, the assets I've built and rebuilt, the businesses still in play, and the fact that at 50 my horizon is genuinely different than it was at 30.
One of the questions I keep asking my attorney is: what will my family still own in 100 years if I don't build the structure now? The honest answer is probably "very little." Without a structure, wealth dissipates. The tax code grinds it down, one generation at a time, until there's nothing left. With a structure, wealth compounds quietly for a century. The difference is whether somebody in this generation took the long view.
The Challenge
What will your family still own in 100 years if you don't build the structure? Not what will you own. What will they own — the grandkids you haven't met, the great-grandkids who won't know your name, the family members who will benefit from decisions you made before they were born. If the honest answer is "nothing," then you haven't been thinking in the right window. Start this month. Find an estate attorney who regularly drafts dynasty trusts and QPRTs. Ask them to walk you through a 100-year projection. The conversation alone will change how you think about the rest of your planning.
