Estate Planning Strategies for Ultra-High-Net-Worth Families

Key Takeaways

• Ultra-high-net-worth generally begins around $30 million in net worth. At that level the planning problem shifts from “who gets what” to taxes, liquidity, control and governance.

• The 2026 federal estate and gift tax exclusion is $15 million per person, or $30 million for a married couple with both exemptions intact. Transfers above the available exemption face a federal rate of up to 40%.

• The larger risk is usually not the size of the tax bill. It is not having the cash to pay it. Stocks and real estate made up nearly 57% of assets reported on estate tax returns filed in 2024.

• Trusts do the heavy lifting, but the right structure depends on whether you are optimizing for estate tax savings or for a basis adjustment at death. Those two goals often pull in opposite directions.

• Governance is the most common weakness. Among family offices with an average family net worth of $2.7 billion, only 35% had a defined succession plan and only 27% had a structured process for preparing heirs.

• State estate taxes apply far below the federal threshold. Oregon’s exemption is $1 million, and Washington taxes estates above $3 million.

Cerulli projects that roughly $124 trillion will change hands through 2048 — approximately $105 trillion to heirs and $18 trillion to charity, with nearly $100 trillion of it originating with Baby Boomers and older generations. It is the largest transfer of private wealth in history, and a meaningful share of it belongs to families whose plans have never been stress-tested against the estate they actually own today.

That is the pattern I see most often. A family built an estate plan fifteen years ago when the balance sheet read $6 million. The documents were competent and the attorney was good. But the business tripled, a real estate partnership matured, a concentrated stock position did what concentrated positions occasionally do, and now the same documents are governing $60 million. Nothing about the plan is wrong, exactly. It was built for a different estate and a far smaller legacy.

At this level, estate planning is a coordination problem rather than a document problem. The will and the revocable trust are table stakes. What determines whether wealth survives the transfer is how well the moving parts — transfer tax, income tax, liquidity, entity structure, insurance, governance, family readiness — work together over decades. What follows puts the most consequential material first.

Part One: Start Here

Why Estate Planning Changes Once You Cross $30 Million

The working definition of ultra-high-net-worth is a net worth above $30 million — the tier above what most advisors mean when they say high-net-worth individuals. Altrata counted approximately 556,850 of them worldwide in 2025, up 14.4% in a single year, holding roughly $63.8 trillion combined.

What changes at that threshold is not the emotional content of the decision. Wealthy families want what every family wants: take care of the spouse, be fair to the children, do not start a war. What changes is how many objectives have to be satisfied at once, and how sharply they conflict.

A plan at this level has to answer seven questions simultaneously:

1. Minimize transfer taxes through exemptions, lifetime gifting, trusts and charitable structures.
2. Preserve income tax efficiency, because basis, capital gains and retirement account treatment can outweigh estate tax savings on certain assets.
3. Maintain liquidity, so taxes never force a sale at the wrong moment.
4. Protect the assets that matter most — operating companies, real estate, concentrated equity, digital holdings.
5. Establish governance over trustees, boards, voting rights and how decisions get made once you are gone.
6. Prepare the next generation, which is different from transferring assets to them.
7. Preserve flexibility, because tax law, marriages, residences, valuations and markets will all change.

A will and a revocable trust address exactly one of those seven. That gap is why so many large estates look well-planned on paper and behave badly in practice.

The 2026 Numbers Every High-Net-Worth Family Should Know

Before any structure is discussed, it helps to have the current figures in front of you.

Item	2026 Figure
Federal estate and gift tax exclusion	$15 million per person / $30 million per couple
Top federal transfer tax rate	40%
Generation-skipping transfer (GST) tax exemption	$15 million per person
Annual gift tax exclusion	$19,000 per recipient ($38,000 per couple)
Annual exclusion for a noncitizen spouse	$194,000
IRS Section 7520 rate (September 2026)	5.4%

The arithmetic is unforgiving above the exemption. Take a married couple with a $50 million estate who preserved both exemptions. Thirty million passes free of federal estate tax. The remaining $20 million is exposed at rates reaching 40% — roughly an $8 million liability, payable in most cases within nine months of death.

It is worth understanding how concentrated this tax is. The IRS received only 7,195 estate tax returns in 2024, and those returns reported more than $23.3 billion in net estate tax. A very small number of families pay this tax, and they pay a great deal of it.

One more note on the exclusion. It is $15 million today. It has been $600,000, $1 million, $3.5 million, $5 million and $11.7 million within the working lifetime of advisors still practicing. I do not build wealth management plans on the assumption that any exemption amount is permanent, and I would encourage you not to either.

Where I Tell Wealthy Families to Start

Most people arrive at my office wanting to talk about grantor retained annuity trusts. I understand the appeal. But the largest and most preventable losses I see happen well before that level of sophistication — they happen in the plumbing. Here is the sequence I recommend, and it deliberately puts the unglamorous work first.

Build a real asset inventory. Every asset and liability at current fair market value, categorized: real estate, financial accounts, private investments, business interests, digital assets, personal property. Executors are generally required to compile exactly this within 90 days of death. Doing it now, while you are the one who knows where everything is, saves your family months.

Audit titling and beneficiary designations against the plan. This is where I find the most damage. A beneficiary designation on a retirement account or insurance policy overrides your trust document. I have reviewed plans where a meticulously drafted dynasty trust was undercut by a 401(k) form from 1998 that still named an ex-spouse. A one-page asset map — each account, current owner, primary and contingent beneficiary — surfaces these conflicts in an afternoon.

Run a liquidity projection. Estimate the federal and state tax owed if you died this year, then compare it to the cash and marketable assets available to pay it. If those numbers are not close, you have found your most urgent problem.

Confirm portability if you have lost a spouse. A survivor can preserve a deceased spouse’s unused federal exclusion, but it generally requires filing Form 706 even when no tax is due. The IRS allows certain estates to make a late portability election on or before the fifth anniversary of death. An estate that looked too small to owe tax at the first death can become much larger during the survivor’s lifetime.

Check your state’s exemption, not just the federal one. More on that below.

Only then design the trust structures. Sophisticated planning built on an inaccurate inventory and mismatched beneficiary forms will not do what you think it does.

Part Two: The Core Strategies

Gifting and Tax Strategies That Shrink a Taxable Estate

Of all the tax strategies available to a large estate, lifetime gifting is the most straightforward — and it is chronically underused by the families who would benefit most.

The annual exclusion lets you give $19,000 per recipient in 2026 without touching your lifetime exemption or filing a return — $38,000 as a married couple. The critical point, which surprises people regularly, is that the exclusion applies per recipient rather than as a total annual cap.

Consider a couple with four children and eight grandchildren. Twelve recipients at $38,000 is $456,000 transferred in a single year using none of the lifetime exemption. Over ten years that is more than $4.5 million out of the taxable estate, before counting appreciation in the recipients’ hands.

There is a non-tax argument for gifting as well, and I think it is underrated. Giving during your lifetime lets you watch the legacy do its work. A down payment that changes a child’s trajectory at 30 accomplishes something the same dollars arriving at 60 simply cannot.

Then there is a provision I wish more families used. Tuition and medical expenses paid directly to the institution or provider do not count against the annual exclusion at all. The tuition payment must go to the school itself and must be for tuition rather than housing or books. Medical payments must go directly to the provider.

That stacks nicely. A grandparent can pay a grandchild’s $80,000 university tuition directly to the school and still make a separate $19,000 annual exclusion gift to that grandchild the same year. For a family with a dozen descendants moving through private school, college and graduate programs, direct payments become a substantial transfer channel most people never think of as estate planning.

The tradeoff nobody mentions until it is too late

Here I want to slow down, because this is the most common analytical error I see in large estates.

Property received as a lifetime gift generally retains the donor’s cost basis. Property inherited at death generally receives a basis equal to fair market value on the date of death.

Suppose you own stock worth $10 million with a $1 million basis (what you initially invested). Gift it during your lifetime and your child likely takes that $1 million basis — a $9 million embedded gain waiting to be realized. Hold it until death and the basis may adjust to roughly $10 million, and the embedded gain disappears.

So the question is not “how do we get the most assets out of the estate?” It is: which assets should be transferred, which should stay, and which tax are we actually trying to minimize?

Well above the exemption, avoiding a 40% estate tax usually dominates. Near the line, preserving the basis adjustment can be worth more. And within a single estate the answer often differs asset by asset. High-basis assets and assets expected to appreciate rapidly are natural candidates for lifetime transfer. Low-basis, slower-growth assets frequently belong in the estate. Getting that sorting right is worth more than most of the advanced structures combined.

How Trusts Give You Control Over Family Wealth

A trust does two distinct jobs, and it helps to keep them separate. Some trusts organize and protect family wealth. Others move value out of your estate.

Revocable (living) trusts let you retain full control. You can amend terms, change beneficiaries or terminate the trust. Assets pass without probate, saving time, cost and publicity. What a revocable trust does not do is reduce your taxable estate — the IRS treats it as an extension of you.

Irrevocable trusts require you to give up control and ownership, and in exchange the assets sit outside your taxable estate and beyond the reach of many creditors. That is the essential trade in nearly all advanced planning: control surrendered for tax savings and protection gained.

Special needs trusts provide for a beneficiary with a disability without disqualifying them from Medicaid, Supplemental Security Income and similar programs.

Beyond tax, trusts give you something families consistently undervalue: the ability to set timing and conditions. Outright inheritance at 25 is a decision. A trust distributing across decades, with provisions for education, business formation or a home purchase, and protection against divorce and creditors, is a different and usually better one. Inheritances today are far larger than a generation ago, and the case for structure has grown with them.

Advanced Trust Strategies for Ultra-High-Net-Worth Estates

Once the foundation is sound, advanced trust strategies do the real work of moving value across generations. I will describe each briefly and honestly, including what can go wrong.

Spousal lifetime access trust (SLAT)

One spouse transfers assets into an irrevocable trust benefiting the other, often with children and later generations as remainder beneficiaries. The assets and their growth sit outside the donor spouse’s taxable estate while the beneficiary spouse still receives distributions.

The appeal is obvious. A couple with a $50 million estate might move as much as $15 million into a SLAT in 2026, with all subsequent appreciation occurring outside the donor’s estate, while the family retains practical access through the beneficiary spouse.

The caveats are real. A SLAT is irrevocable. Divorce or the death of the beneficiary spouse ends the donor’s indirect access. SLAT assets generally receive no basis adjustment when the donor later dies. And if both spouses create mirror-image SLATs for each other, the reciprocal trust doctrine can collapse the arrangement entirely. That doctrine is judge-made rather than statutory, which makes experienced counsel essential rather than optional.

Grantor retained annuity trust (GRAT)

You transfer assets into an irrevocable trust and retain an annuity for a fixed term. If the assets outperform the IRS hurdle rate, the excess appreciation passes to heirs at little or no gift tax cost.

As of September 2026 the Section 7520 rate is 5.4%, and the rate resets monthly. GRATs suit founders and families holding volatile or rapidly appreciating assets, and they are unusually attractive after a market decline — a depressed valuation going in means more of the eventual recovery happens inside the trust rather than inside your estate. Many practitioners use rolling GRATs, layering short-term trusts at intervals so a single bad term does not waste the strategy.

Sale to an intentionally defective grantor trust (IDGT)

Rather than gifting a large asset outright, you sell it to a grantor trust in exchange for a promissory note. Appreciation above the note’s economics accumulates outside your estate.

“Defective” is unfortunate terminology. It simply means the trust is disregarded for income tax purposes while respected for estate tax purposes, so you continue paying income tax on trust earnings. That sounds like a burden. It is actually the most elegant feature of the structure.

IRS Revenue Ruling 2004-64 confirms that a grantor’s payment of income tax on grantor trust income is not treated as an additional gift to the beneficiaries. In practice, your estate shrinks each year by the tax you pay while the trust assets compound undiminished for your heirs. Practitioners call this the tax burn, and over a long horizon it can transfer more value than the original gift.

Dynasty and generation-skipping trusts

The $15 million GST exemption can be allocated to trusts benefiting grandchildren and later generations. Properly structured, appreciation continues inside the trust rather than being taxed again at each generational transfer.

To clear up a persistent confusion: a generation-skipping trust does not skip your children. They can be beneficiaries throughout their lives. What skips is the transfer tax that would otherwise apply at each of their deaths.

The details here are intensely state-specific — trust duration, creditor protection, trustee powers, directed trust statutes and rule-against-perpetuities provisions all vary. Which is why trust jurisdiction itself becomes a planning decision. It is common to site a dynasty trust in a state with favorable statutes regardless of where the family lives.

Irrevocable life insurance trust (ILIT)

Life insurance solves the liquidity problem better than almost anything else, but only if it is owned correctly.

The IRS includes life insurance proceeds in the gross estate when the decedent retained incidents of ownership — the power to change beneficiaries, cancel the policy, assign it or borrow against it. An ILIT owns the policy instead, keeping the death benefit out of your taxable estate and out of your lifetime exemption.

The three-year rule matters enormously here. Transferring an existing policy into a trust within three years of death can pull the proceeds back into the gross estate. Having the trust own the policy from the outset is worth the additional setup effort.

Charitable remainder and charitable lead trusts

A charitable remainder trust pays income to you or other noncharitable beneficiaries for a term or for life, with the remainder going to charity. The charitable remainder must be at least 10% of the initial fair market value contributed, payouts generally fall between 5% and 50%, and a fixed term cannot exceed 20 years. CRTs are especially useful for highly appreciated assets, because the structure can allow diversification without the immediate capital gains hit of an outright sale.

A charitable lead trust runs in the opposite direction. Charity receives payments for a defined term, and the remaining assets then pass to your children or grandchildren. For families with genuine philanthropic intent, a CLT combines giving with an intergenerational transfer, particularly when the assets appreciate during the charitable term. With roughly $18 trillion of the coming transfer projected to flow to charities, these structures deserve more attention than they get.

A word of caution on all of it

These strategies stack. A SLAT can carry dynasty provisions. An IDGT sale can be paired with an ILIT. Rolling GRATs can run alongside an annual gifting program.

But each requires genuine economic substance. Valuation discounts for lack of marketability or control are not automatic — they require defensible facts, proper structuring and qualified appraisal work. The IRS imposes a 20% penalty for substantial valuation understatements, rising to 40% for gross understatements. Structures built purely to manufacture a tax result are the ones that get challenged and lose.

Liquidity: The Problem That Forces Families to Sell

If I could get one point across in this entire article, it would be this one. The estate tax bill is rarely the disaster. The disaster is having to sell something to pay it.

The IRS data makes the risk plain. Stocks and real estate represented nearly 57% of assets on estate tax returns filed in 2024. Among estates of at least $50 million, roughly 45% was held in stocks alone.

So picture a family worth $100 million on paper whose wealth is an operating company, three commercial properties and a private portfolio. The federal estate tax is due in cash, generally within nine months. The family has $2 million in liquid reserves. The heirs are now forced sellers, on a deadline, in whatever market happens to exist that year — and buyers know it. That is how a $100 million estate becomes a $70 million estate without anyone making a mistake.

Liquidity planning generally draws on four sources: life insurance held in an ILIT and sized against the projected tax; credit facilities arranged in advance against securities or real estate; liquid reserves deliberately maintained; and funded redemption or buy-sell agreements at the entity level.

There is also a statutory option worth knowing. Under IRC Section 6166, an estate holding a closely held business may defer part of the federal estate tax if the qualifying business interest exceeds 35% of the adjusted gross estate. When the requirements are met, the executor can generally defer payment for up to five years and then pay in as many as ten annual installments. Interest accrues, but the cash flow relief can be the difference between keeping the company and selling it.

Which leads to a reframe I offer clients often: the objective is not always to eliminate the estate tax. Sometimes it is simply to make sure the tax never dictates the timing of a sale.

Business Succession Planning When the Company Is the Estate

For families whose wealth is entrepreneurial, business succession is usually the hardest part of the plan and the most often deferred. PwC’s 2025 U.S. Family Business Survey found that 44% of U.S. family businesses said succession planning had affected the business during the prior year.

The most useful thing I can offer is a framework separating three questions people habitually merge into one:

Who owns the company? Who controls the company? Who operates the company?

These do not have to be the same people, and at scale they usually should not be. A child can inherit meaningful economic ownership without becoming chief executive. A professional management team can run the business while the family retains ownership through trusts or a holding entity. A founder can transfer economic interests gradually while keeping voting control through the transition.

The tools are entity-level. LLCs and limited partnerships allow voting and nonvoting interests. A family limited partnership can hold real estate or securities with general partner control concentrated and limited partner economics distributed. Buy-sell agreements set terms, valuation method and funding before anyone is emotional about it.

PwC’s broader point is one I endorse: separate ownership succession from leadership succession, and decide honestly whether future management should remain in the family. The most damaging succession plans I have seen assumed a child wanted the job and never asked.

State Estate Taxes Can Undo Federal Planning

The $15 million federal exemption gives many high-net-worth families a false sense of security. Twelve states plus the District of Columbia impose an estate tax, five impose an inheritance tax, and Maryland imposes both.

State	2026 Estate Tax Exemption
Oregon	$1 million
Rhode Island	$1.84 million
Massachusetts	$2 million
Minnesota	$3 million
Washington	$3 million
Illinois	$4 million
District of Columbia	$4.99 million
Maryland	$5 million
Vermont	$5 million
Hawaii	$5.49 million
Maine	$7 million
New York	$7.35 million
Connecticut	$15 million

Washington is a useful illustration of how quickly this moves. The state raised its top estate tax rate to 35% in mid-2025, then reversed course: for deaths on or after July 1, 2026, the top rate is back to 20% and the exemption is fixed at $3 million with inflation indexing suspended. An estate in a state like that can owe substantial state tax while owing nothing federally, and the rules can change between the year you draft and the year you die.

Two practical implications. First, property you own in a state with an estate tax is generally taxable there whether or not you live there — a California resident with an Oregon vacation home has Oregon exposure. Second, for families with homes in several states, domicile becomes a live planning question. But a domicile change requires genuine substance: voter registration, driver’s license, time actually spent, where your physicians and advisors are, where your household goods live. A change of mailing address is not a change of domicile, and states with revenue at stake audit this aggressively.

Part Three: What Most Plans Leave Out

Governance Is Where Generational Wealth Actually Survives

The 2026 UBS Global Family Office Report surveyed 307 family offices across more than 30 markets, representing families with an average net worth of $2.7 billion. These are among the best-advised families in the world.

Sixty-eight percent had formal processes for measuring financial performance and 60% had investment committees. But fewer than half had formal governance frameworks with board-level oversight, and only 35% had a defined succession plan for the family office.

I find that clarifying rather than discouraging. It tells you the hard part of this work is not tax structuring. Families with billions of dollars and access to any advisor they want have largely solved that. What remains unsolved, even at that altitude, is the human architecture.

Governance is the set of agreements determining how decisions get made once the founder is no longer in the room: a family constitution stating the purpose of the wealth and the principles guiding distributions; a family council with defined membership and authority; trustee selection and succession; investment committee structure and voting authority; a written distribution policy, so a no is a policy rather than an insult; and a conflict resolution mechanism agreed on before anyone needs it.

One structural element deserves special mention. A trust protector holds certain powers over a trust without serving as trustee. For long-duration dynasty trusts this is close to essential — every individual you name today will eventually be gone, and tax law will change several times over the trust’s life. A trust protector can remove and replace trustees and modify administrative provisions to keep the trust efficient. Without one, the alternative is petitioning a court, which is slow, expensive and public.

The point I want to leave you with: tax-efficient wealth transfer and successful wealth succession are two different accomplishments. Plenty of families achieve the first and fail at the second.

Preparing Heirs, Not Just Transferring Assets

The same research exposes a sharper gap. Only 27% of family offices had a structured process for educating and preparing heirs for their future roles.

UBS’s earlier 2025 study looked at the conversation itself. Among families that had succession plans, only 26% consulted the next generation from the outset. Another 36% brought younger family members in after the first generation had already decided. And 35% did not consult them at all.

Meanwhile, 64% of those families identified tax-efficient wealth transfer as a major succession challenge, while 43% cited preparing the next generation to handle wealth responsibly.

Read those figures together and the mismatch is hard to miss. Families are spending their effort on the problem money and expertise can solve, and comparatively little on the problem only time and attention can solve.

Preparation is not complicated, though it is slow. It means giving adult children real information about the family balance sheet rather than vague reassurance. It means letting them make smaller decisions with real consequences while you are still here to discuss the outcome. It means involving them in philanthropic decisions, which is a low-stakes way to practice stewardship. And it means being candid about the structures — a child who first learns about a dynasty trust from an attorney reading documents has been set up to resent it.

Four Details That Break a Large Estate Plan

1. Retirement accounts follow different rules. For most non-spouse beneficiaries, the SECURE Act’s ten-year rule requires an inherited IRA or defined contribution account to be fully distributed by the end of the tenth year after death. Certain eligible designated beneficiaries — surviving spouses, some disabled or chronically ill beneficiaries — are treated differently. For a wealthy family, that can dump a large taxable distribution on heirs already in the top bracket. Worse, a large traditional IRA inside a taxable estate faces estate tax and then income tax on distribution. Beneficiary designations, charitable beneficiaries and any trust named as beneficiary need to be coordinated with the plan rather than filled out afterward. Roth conversions and insurance-funded alternatives are both worth modeling.

2. Digital assets need an access plan, not just a tax treatment. Cryptocurrency, stablecoins and NFTs are property for federal tax purposes, and the IRS includes digital assets among those that may be part of a gross estate. The tax question is straightforward; the practical one is not. An executor may know the decedent held Bitcoin and still be unable to reach it without wallet information, private keys, authentication devices or exchange credentials. Your inventory should address how an authorized fiduciary identifies and accesses these holdings without exposing credentials prematurely.

3. Cross-border families need a separate layer. UBS reports that 36% of billionaires surveyed had relocated at least once, with another 9% considering it. If your family has foreign property, a cross-border marriage or international business interests, you face multiple inheritance regimes, possible forced heirship rules and treaty questions. Citizenship matters specifically: the annual exclusion for gifts to a noncitizen spouse is $194,000 in 2026 rather than $19,000, and the unlimited marital deduction generally does not apply to a noncitizen surviving spouse unless the requirements of a qualified domestic trust (QDOT) are satisfied. That has caught otherwise well-planned families.

4. Valuations deserve their own attention. Large estates commonly hold private companies, partnership interests, commercial real estate, art and carried interests — assets with no observable market price. Federal transfer taxes require fair market value, and that number materially determines what is owed. Build the appraisal relationships before you need them, and update valuations on a schedule rather than in a crisis.

Building the Team, and Keeping the Estate Plan Current

No single professional can carry all of this. A complete estate plan generally involves an estate planning attorney, a tax advisor, a wealth management team, an insurance specialist, a valuation professional, and sometimes transaction counsel if a business sale is contemplated.

What matters more than the roster is whether anyone is quarterbacking. I have reviewed situations where every individual advisor was excellent and the aggregate plan was incoherent — because the attorney drafted a trust the investment team did not know existed, and the insurance was owned in a way that undid what the trust was meant to accomplish.

On timing: review annually, and immediately upon a marriage or divorce, a birth or death, a business sale or liquidity event, a change of residence, a significant change in asset values, or a change in the tax law. In my experience the trustee designation is the provision most often out of date, followed by beneficiary designations and the level of asset protection built in for the next generation.

Conclusion

A Closing Thought

Most of what I have described is technical, and the technical work matters — a well-designed structure can preserve tens of millions that would otherwise go to transfer taxes or forced sales. But the families I have watched hand down wealth successfully over two and three generations did not distinguish themselves through clever structuring. They started earlier than they needed to, they talked to their children honestly, and they treated the legacy as something to be built deliberately rather than something that would take care of itself.

If you already have an estate plan, the most useful next step is usually not building something new. It is having someone review what exists against the estate you own today, and against the seven objectives at the top of this article. That review frequently surfaces a mismatched beneficiary designation or a liquidity gap far more consequential than any structure you might add.

If you would like a second set of eyes on your current plan, my team at Guardian Resources is glad to have that conversation.

FAQs: Estate Planning for High-Net-Worth Individuals

At what net worth does advanced planning become necessary?

Typically somewhere around $5 million, but complexity matters more than any dollar figure. Families with closely held businesses, multiple properties, blended families, international ties or rapidly appreciating assets often need advanced structures well below that. The goal is to build them early, while you still have options.

How much can I give away in 2026 without triggering gift tax?

You can give $19,000 per recipient — $38,000 as a married couple — to as many people as you like, with no gift tax and no return. Beyond that, you can transfer up to your $15 million lifetime exemption without paying gift tax, though a Form 709 is required and the amount reduces what remains at death. Tuition and medical expenses paid directly to the institution or provider fall outside both limits entirely.

Should I use my full $15 million exemption now?

It depends on whether you can afford to part with the assets permanently, and on how the basis analysis runs. Using the exemption on rapidly appreciating assets removes both the asset and its growth from your estate, which is powerful. But gifted assets carry over your basis, and irrevocable means irrevocable. I would rather see a family use part of the exemption on the right assets than all of it on the wrong ones.

How do trusts reduce estate and gift taxes?

Irrevocable trusts move assets out of your taxable estate so future appreciation occurs outside it. Grantor trusts add a second benefit, since your payment of the trust’s income tax shrinks your estate without counting as an additional gift. Charitable trusts remove the charitable portion while advancing your philanthropic goals. Revocable trusts avoid probate but provide no estate tax reduction.

What happens if my estate does not have the cash to pay the estate tax?

The tax is generally due within nine months of death, and if liquid assets are not there, the executor sells something. That is the scenario liquidity planning exists to prevent. If a closely held business makes up more than 35% of the adjusted gross estate, Section 6166 may allow deferral for up to five years followed by as many as ten installments.

How often should we revisit the plan?

At least annually, and immediately after any significant life, business or legal event. A plan reviewed once a decade is a plan built for a family that no longer exists.
