Structuring the family LLC: you can't slice a building

Every fact pattern so far has built walls against outsiders. This one solves a different problem: how a family hands a business, a portfolio, or a building to the next generation without the handoff destroying the thing being handed off.

The problem is division. A building cannot be split among three children. A business cannot give one heir the customers and another the equipment. And the assets that families most want to pass down, the rental portfolio, the operating company, the land, are exactly the assets that resist being passed down, because you cannot slice them.

You can slice a company. Put the building in an LLC and the building is suddenly divisible into membership percentages, giftable in any size, on any schedule, with control assigned separately from ownership. That single conversion, from an unsliceable asset into sliceable interests, is the entire foundation of the family LLC, and everything else on this page is the craft of slicing well.

The move, in one worked picture

Parents own a $4,000,000 rental portfolio and want it to reach three children. Deeding buildings to kids is a disaster on every axis: it fractures title, and it hands creditors and future ex-spouses direct claims on real estate while giving up all control on day one.

The family LLC version: the portfolio goes into an LLC, manager-managed, with the parents as managers. The parents then gift membership interests over time, in slices sized to the annual gift exclusion, currently $19,000 per recipient per year, $38,000 from a married couple, to any number of recipients, without touching the lifetime exemption or filing anything. Three kids and their three spouses means the couple can move $228,000 of value a year, every year, quietly. The children own a growing share of the economics. The parents still sign everything and decide everything, distributing or retaining cash as they judge, because management was never gifted. Ownership moves; control stays.

This is the manager-managed structure doing estate work, and the freedom of contract the state-law spine celebrates is what makes the fine-tuning legal: the operating agreement can restrict transfers and keep the interests inside the bloodline.

What the walls do for a family

The doctrines from the state-law spine bite in this pattern too, but here they mostly bite in the family’s favor.

A child’s divorce or judgment creditor is the nightmare that motivates half these structures, and the LLC’s machinery answers it. The creditor of a member reaches the membership interest, not the buildings, and in the better states gets only a charging order: a right to distributions the manager decides to make, which the parents, as managers, can decide not to make. The default rules add the quieter protection: a membership interest transferred without the required consent carries economics only, no vote and no information rights, so an outsider who acquires a slice acquires a seat in the waiting room.

Trusts stack on cleanly. Interests gifted to trusts for the children instead of to the children outright add divorce and spendthrift protection and open the generation-skipping toolbox, and the trusts page carries the machinery of trust-owned LLCs. Serious family structures are usually LLC interests held by trusts, and the two tools were built to nest.

One warning travels with all of it. These walls hold when built early and breached when built late; moving assets into a family LLC after the lawsuit or the divorce filing arrives is a fraudulent transfer with a family label on it, and the timing refrain from this entire site applies with no family discount.

The tax advice most families follow is out of date

The classic family LLC pitch was an estate tax pitch: gift interests at a discount, shrink the taxable estate, beat the 40 percent tax. That pitch made sense when the exemption was a fraction of today’s. As of 2026 the federal estate and gift exemption is $15,000,000 per person, $30,000,000 per married couple, permanent under the 2025 law and indexed for inflation. Most families, including most families wealthy enough to read this page, will never owe a dollar of federal estate tax.

That flips a piece of advice most people have not heard flipped. Gifted assets carry the giver’s tax basis; inherited assets get a stepped-up basis at death, erasing decades of built-in capital gain. A family under the exemption that aggressively gifts appreciated buildings to the kids saves estate tax it was never going to owe and costs the children a step-up they were going to get, a real capital gains bill traded for imaginary savings. For those families the honest advice is nearly the reverse of the seminar: hold appreciated assets until death, take the step-up, and run the family LLC for what it still delivers in full, which is control, creditor protection, and an orderly succession.

Above the exemption, the classic playbook is alive, and one of its tools deserves its honest paragraph. Valuation discounts recognize that a minority interest in a family LLC, unsaleable and outvoted, is worth less than its share of the underlying assets, so a gifted slice consumes less exemption than the assets inside it. The discounts are real and courts allow them, and the IRS attacks the abusive versions relentlessly and wins: the deathbed funding, the parents who kept living off the LLC’s assets as if nothing was gifted, the entity with no purpose beyond the discount. The pattern in the losses is that the structure was a costume. Families that run the LLC as a real entity, with real appraisals and a genuine business purpose, keep their discounts; families that wanted only the tax number hand the whole pot back with interest. And state estate taxes complicate the picture separately, since several states tax estates at thresholds far below the federal line; the state pages will carry those specifics.

What stays out of the box

Two assets, held out by name. The family home stays out: putting a residence the parents keep living in inside the LLC is the exact retained-enjoyment fact pattern that pulls assets back into the taxable estate, and it forfeits the home-sale exclusion and homestead protections that make a personal residence its own best structure. And personal spending stays out entirely. A family LLC whose account pays the parents’ groceries is commingling twice over: it invites veil piercing like any sloppy LLC, and it is the retained-control evidence that unwinds the estate plan. The family label makes the discipline harder and more necessary at once, because nothing feels less like a formality than family money.

Income tax housekeeping rounds out the list. A multi-member family LLC files a partnership return and sends every member a K-1, which means gifted interests come with the phantom income problem the distributions page explains: a child can owe tax on profits the managers retained. The operating agreement’s tax-distribution clause is the fix, and it should be drafted, not assumed. And the default labels stay on; everything the choice of entity page says about appreciating assets never entering an S-corp applies to family structures with extra force, since the step-up planning above depends on the flexibility the default labels preserve.

The agreement is the succession plan

The documents most families fight over were never written. Who manages when the parents cannot. Whether a sibling can sell, and to whom, and at what price. What happens to a divorcing child’s interest. Whether the portfolio is held or liquidated after the second death. Every one of those questions has a default answer written by the legislature, the defaults and exits pages explain how poorly those defaults fit anyone, and a family LLC without a real operating agreement has simply chosen to litigate the answers later, among grieving siblings, which is the most expensive drafting venue on earth. The clause-by-clause drafting belongs to this site’s operating agreement manual; the decision to treat the agreement as the family constitution belongs at formation.

The bottom line

Convert the unsliceable into slices: assets into an LLC, control into a manager role the parents keep, ownership into interests that move on the family’s schedule, inside trusts where the protection is worth the plumbing. Below the federal exemption, where most families live, run the structure for governance and protection, keep appreciated assets for the step-up, and treat aggressive gifting as the outdated advice it now is. Above the exemption, gift early, appraise honestly, and run the entity like the real company it must be, because every collapsed family structure in the case law was a costume, and the families that keep the benefits are the ones for whom the LLC was true.
