Advanced estate planning is how you move wealth out of your taxable estate before the federal government takes 40% of everything above the exemption. For 2026, that exemption sits at $15 million per individual and $30 million for a married couple under the One Big Beautiful Bill Act signed in July 2025. The practical stakes are easy to see: a $25 million estate with no planning could owe roughly $4 million in federal estate tax, while the same estate, properly structured, might owe nothing.
What follows is the toolkit — the exemption rules you build on, the trusts and entities that move assets and future growth out of your estate, the charitable and business succession pieces that solve specific problems, and the execution work that quietly decides whether any of it holds up.
What You Can Shield in 2026
The basic exclusion amount for 2026 is $15 million per person.1Office of the Law Revision Counsel. 26 U.S. Code 2010 – Unified Credit Against Estate Tax Married couples who combine their exemptions through portability can shelter up to $30 million. Everything above the threshold faces a graduated rate that tops out at 40%.2Office of the Law Revision Counsel. 26 USC 2001 – Imposition and Rate of Tax
The generation-skipping transfer (GST) tax applies its own separate exemption to prevent families from skipping a generation by leaving assets directly to grandchildren. The GST exemption generally matches the estate tax exemption.
Separately, the annual gift tax exclusion for 2026 is $19,000 per recipient.3Internal Revenue Service. Gifts and Inheritances You can give $19,000 to as many people as you want each year without touching your lifetime exemption or filing a gift tax return. Married couples can combine this through gift splitting to give $38,000 per recipient. The annual exclusion is the simplest wealth transfer tool available, and overlooking it leaves tax-free transfers on the table every year.
Portability of a Deceased Spouse’s Exemption
When a spouse dies without using the full $15 million exemption, the surviving spouse can claim what’s left. This is the deceased spousal unused exclusion, or DSUE, and it does not happen automatically. The estate’s representative must file Form 706 within nine months of death, even if the estate owes no tax.4Internal Revenue Service. Frequently Asked Questions on Estate Taxes A six-month extension is available on Form 4768.
If the deadline is missed, Revenue Procedure 2022-32 allows a late portability election up to five years after death, provided the estate was not otherwise required to file. Miss that window too, and the surviving spouse permanently loses access to up to $15 million of additional exemption. This is one of the most common and costly mistakes in estate planning.
Why Lifetime Transfers Cost You the Step-Up
Nearly every advanced strategy requires moving assets out of your name while you’re alive, and that creates a real tension with IRC Section 1014. Under Section 1014, most assets you still own at death receive a new tax basis equal to their fair market value on that date. If you bought stock for $100,000 and it’s worth $2 million when you die, your heirs inherit it with a $2 million basis. Sell at $2 million, owe zero capital gains tax.
Assets transferred into an irrevocable trust during your lifetime generally lose that step-up. You’ve removed them from your taxable estate, but you’ve locked in your original basis for the next generation. The right answer depends on the math: how much estate tax you avoid versus how much capital gains tax your heirs will eventually pay. Highly appreciated assets you expect to be held long term often stay in your estate on purpose. Assets you expect to grow aggressively from here are the better candidates for lifetime transfer.
Community property states offer an additional advantage: both halves of community property receive a step-up when one spouse dies, not just the decedent’s half. Retirement accounts, annuities, and cash do not receive a step-up at all, because they’re taxed as ordinary income when distributed regardless of basis.
Irrevocable Trusts That Move Growth Out of Your Estate
Irrevocable trusts are the workhorses here. Once assets go in, they and their future appreciation leave your taxable estate. The price is giving up direct control. Different trust types solve different problems.
Grantor Retained Annuity Trusts
A Grantor Retained Annuity Trust (GRAT) lets you transfer assets into a trust while retaining a fixed annual payment for a set number of years. The gift tax value of what your beneficiaries eventually receive is the asset value minus the present value of the annuity payments you keep. Section 2702 requires the retained interest to be structured as a “qualified interest” or it gets valued at zero.5Office of the Law Revision Counsel. 26 U.S. Code 2702 – Special Valuation Rules in Case of Transfers of Interests in Trusts
The real power shows up in a “zeroed-out” GRAT: annuity payments set high enough that the calculated gift value is essentially zero. If the trust’s assets grow faster than the IRS discount rate (the Section 7520 rate), all of that excess growth passes to your beneficiaries free of gift and estate tax. The catch is mortality risk. If you die during the GRAT term, some or all of the assets come back into your estate and the strategy accomplished nothing. Short two- or three-year terms reduce the risk, and many planners run a series of rolling short-term GRATs rather than one long trust.
Qualified Personal Residence Trusts
A Qualified Personal Residence Trust (QPRT) applies the same idea to your home. You transfer a primary or secondary residence into the trust, keep the right to live there for a set number of years, and at the end of the term ownership passes to your beneficiaries. The taxable gift is discounted steeply because you’re giving a future interest, not immediate ownership. You can use QPRTs for up to two residences. Die before the term expires and the house comes back into your estate. Survive the term and want to keep living there, and you’ll need to pay fair-market rent to your beneficiaries.
Irrevocable Life Insurance Trusts
Life insurance proceeds are included in your gross estate if you held any “incidents of ownership” over the policy at death — things like the right to change beneficiaries, borrow against the policy, or cancel it.6Office of the Law Revision Counsel. 26 USC 2042 – Proceeds of Life Insurance An Irrevocable Life Insurance Trust (ILIT) owns the policy itself, so the death benefit stays outside your estate.
Timing matters. Transfer an existing policy to an ILIT and die within three years, and the proceeds get pulled back into your estate as if the transfer never happened.7Office of the Law Revision Counsel. 26 U.S. Code 2035 – Adjustments for Certain Gifts Made Within 3 Years of Decedent’s Death The safer approach is to have the ILIT buy a new policy from day one. Premiums are usually funded by annual gifts to the trust that qualify for the $19,000 annual exclusion through Crummey withdrawal powers, which give beneficiaries a short-term right to withdraw contributions.
Spousal Lifetime Access Trusts
A Spousal Lifetime Access Trust (SLAT) addresses the hardest part of giving assets away: losing access to them. One spouse transfers assets into an irrevocable trust that names the other spouse as beneficiary. The assets leave the donor spouse’s taxable estate, but the beneficiary spouse can receive distributions, giving the couple indirect access.
Three risks are worth knowing. Divorce or the death of the beneficiary spouse eliminates the donor’s indirect access unless the trust names successors. SLAT assets generally do not receive a step-up at the donor’s death. And if both spouses create mirror-image SLATs for each other, the IRS can invoke the reciprocal trust doctrine and treat both trusts as if they don’t exist for tax purposes. Meaningful differences in terms, timing, or assets help avoid that outcome.
Intentionally Defective Grantor Trusts
An Intentionally Defective Grantor Trust (IDGT) exploits a deliberate mismatch in the tax code. The trust is drafted to be irrevocable for estate tax purposes (so assets leave your estate) but a grantor trust for income tax purposes (so you personally pay the trust’s income taxes). That “defect” is intentional: every dollar of income tax you pay on the trust’s behalf is effectively a tax-free gift to the beneficiaries that doesn’t count against your lifetime exemption.
The common technique is to sell appreciated assets to the IDGT in exchange for an installment note charging at least the applicable federal rate (AFR). Because the IRS treats you and the trust as the same taxpayer for income tax purposes, the sale triggers no capital gains tax. The assets grow inside the trust, the growth stays out of your estate, and the note payments reduce your estate further as you spend or gift them. Skip the formalities or charge below the AFR and the IRS can recharacterize the sale as a gift.
Entities That Discount What You Transfer
Family Limited Partnerships (FLPs) and Limited Liability Companies (LLCs) consolidate investments, real estate, or business interests under one management structure. The senior generation usually keeps control through general partner or managing member roles while transferring limited interests to children or trusts.
Valuation Discounts
The tax advantage comes from valuation discounts. A 10% limited partnership interest in an entity holding $10 million of assets is not worth $1 million for gift tax purposes, because the holder cannot force a sale, cannot control distributions, and cannot easily sell to an outsider. Appraisers reduce the value for lack of control (which can reach 40%) and for lack of marketability. The combined discount lets you transfer more economic value using less of your lifetime exemption.
The IRS scrutinizes these transfers hard. To survive an audit, the entity needs a legitimate business purpose beyond tax reduction, the operating or partnership agreement has to impose real restrictions on transfers and distributions, and a qualified appraiser must prepare the valuation. The appraiser needs credentials, experience valuing the specific asset type, and no conflict in the transaction. The appraisal has to exist before you file.
Asset Protection
Entities also create a legal barrier between family wealth and individual liabilities. A creditor who wins a judgment against one family member generally cannot seize the underlying assets inside an FLP or LLC. The creditor is limited to a charging order against that member’s distributions. The operating agreement controls how distributions are made and how interests change hands, which for multigenerational wealth is often as valuable as the tax savings.
Charitable Structures
Charitable vehicles reduce the taxable estate while funding causes the family cares about. The two main trust structures run in opposite directions.
Charitable Remainder Trusts
A Charitable Remainder Trust (CRT) pays income to you or your beneficiaries for a term (up to 20 years) or for life, then distributes what remains to charity. The trust must pay out at least 5% and no more than 50% of its asset value annually.8Office of the Law Revision Counsel. 26 U.S. Code 664 – Charitable Remainder Trusts You get a partial income tax deduction in the funding year based on the present value of the charity’s future interest.9Internal Revenue Service. Charitable Remainder Trusts
CRTs work especially well for low-basis appreciated assets. Selling the asset yourself triggers a large capital gains bill. Transferring it to the CRT first lets the trust sell with no immediate capital gains hit, reinvest the full proceeds, and pay you income from a larger pool. The trade-off is that the remainder goes to charity instead of your heirs.
Charitable Lead Trusts
A Charitable Lead Trust (CLT) reverses the order. The charity receives annual payments for a fixed term, and the remainder passes to your heirs when the term ends. The structure performs best in low interest rate environments: when the IRS discount rate is low, the projected value of the charity’s income stream is higher, which pushes the taxable gift of the remainder lower.
Private Foundations
Private foundations give families direct, ongoing control over charitable distributions and investment strategy. The foundation must distribute at least 5% of its net investment assets each year to avoid excise taxes.10Internal Revenue Service. Minimum Investment Return Foundations carry more regulatory overhead than trusts, including self-dealing rules, limits on business holdings, and annual filings. For families with serious philanthropic goals and multigenerational involvement, they’re worth the compliance load.
Passing a Business Without a Fire Sale
Closely held businesses create a specific problem: most of the owner’s wealth sits in an illiquid asset. The business may be worth millions, but the estate cannot easily sell shares to pay the tax bill. Three techniques address this.
Buy-Sell Agreements
A buy-sell agreement is a contract among owners controlling what happens to an interest at death, disability, divorce, or retirement. Good agreements include a valuation formula or periodic appraisal requirement to prevent disputes among heirs and surviving owners. Life or disability insurance typically funds the buyout, so the departing owner’s estate receives cash while the remaining owners acquire the interest without draining operating capital.
Corporate Recapitalization
Recapitalization splits equity into classes. The owner exchanges common stock for voting preferred (retained for control) and nonvoting common (which carries most of the economic upside). The nonvoting interests are then gifted to the next generation, moving future growth out of the owner’s estate while preserving day-to-day control. Section 2701 imposes special valuation rules on these transfers so families cannot artificially understate the retained interest.11Office of the Law Revision Counsel. 26 USC 2701 – Special Valuation Rules in Case of Transfers of Certain Interests in Corporations or Partnerships Retained rights that aren’t “qualified payments” (such as cumulative dividends at a fixed rate) get valued at zero, which inflates the taxable gift. Getting the structure wrong can produce a far larger gift tax bill than anyone expected.
Estate Tax Deferral Under Section 6166
If a closely held business interest represents at least 35% of the decedent’s adjusted gross estate, the estate can elect to pay the portion of estate tax tied to that business over an extended schedule rather than in a lump sum.12Office of the Law Revision Counsel. 26 USC 6166 – Extension of Time for Payment of Estate Tax Where Estate Consists Largely of Interest in Closely Held Business The usual structure is up to five years of interest-only payments followed by ten annual installments of principal and interest. The election must be made on a timely-filed Form 706. It accelerates immediately if the heirs sell 50% or more of the business interest or miss a payment by more than six months. This provision is often what keeps a business running after the founder dies.
Making the Plan Actually Work
Sophisticated structures on paper accomplish nothing until the documents are properly executed and the assets are actually moved. This is where plans quietly fall apart.
Execution and Funding
Trust documents must be signed before witnesses and a notary. Then every intended asset has to be re-titled. Real estate requires recording a new deed with the county recorder. Brokerage accounts need updated registration showing the trust as owner. Bank accounts have to be re-titled or reopened in the trust’s name. Forgetting even one asset is common, and an unfunded trust is a worthless trust. Anything left in your individual name stays in your taxable estate regardless of what the trust document says.
Gift Tax Reporting
Any gift exceeding the $19,000 annual exclusion requires Form 709, due by April 15 of the following year.13Internal Revenue Service. Instructions for Form 709 Its purpose is tracking how much of your lifetime exemption you’ve used. Transfers of hard-to-value assets like FLP interests, closely held stock, or real estate should be supported by a qualified appraisal attached to the return. Understating value triggers penalties and extends the IRS statute of limitations. Overstating wastes exemption. The appraisal is what the IRS will look at first in any audit.
Trust Administration
Irrevocable trusts require active management. Trustees must follow the trust terms, file annual income tax returns (Form 1041 for non-grantor trusts), keep records of distributions, and make investment decisions consistent with their fiduciary duty. Corporate trustees typically charge 0.5% to 2% of trust assets per year. Family members serving as trustees avoid the fee but take on personal liability for mismanagement. Trusts holding entity interests also require the trustee to coordinate with entity management and participate in governance under the operating agreement.
If your estate is anywhere near the exemption threshold, start with the portability filing after a spouse’s death, use the annual exclusion every year, and only then layer in the trusts and entities that fit your specific assets. The techniques work; the follow-through is what decides whether they hold up.
