The tax advantages of using an LLC in estate planning come down to three levers: you can transfer ownership interests at values discounted below the underlying assets, you can push all future appreciation out of your taxable estate, and you can spread income across family members in lower brackets. The federal lifetime estate and gift tax exemption is $15 million for 2026, and the annual gift tax exclusion is $19,000 per recipient, but both go significantly further when what you’re transferring is a minority interest in a family LLC rather than the assets themselves.1Internal Revenue Service. What’s New — Estate and Gift Tax The savings are real. So are the compliance requirements that keep them in place.
Valuation Discounts on Transferred Interests
A 20% interest in an LLC holding $5 million in real estate is not automatically worth $1 million. The recipient can’t force a sale, can’t run day-to-day management alone, and can’t liquidate the company. Those restrictions reduce what a hypothetical buyer would pay, and the IRS recognizes the reduction through a lack-of-control discount.
A second discount applies because no public market exists for interests in your family LLC. Unlike shares of a listed company, these stakes are illiquid and slow to convert to cash. This lack-of-marketability discount stacks on top of the control discount. Courts have accepted combined discounts ranging from 10% to 45%, depending on the specific restrictions written into the operating agreement and the type of assets the LLC holds.
With the 2026 annual exclusion at $19,000 per recipient, a 30% combined discount lets you transfer an interest backed by roughly $27,100 in underlying assets while staying inside the exclusion. A married couple using gift-splitting can move about $54,200 in asset value to each recipient every year without touching the lifetime exemption. Applied to the $15 million lifetime exemption itself, a donor gifting $15 million of discounted interests is really transferring far more than $15 million in underlying asset value.1Internal Revenue Service.

The Statutory Guardrails
Two federal statutes keep discounts honest. Section 2703 lets the IRS disregard any agreement or restriction on property if it isn’t a bona fide business arrangement, if it functions as a device to transfer property to family for less than fair value, or if its terms aren’t comparable to arm’s-length deals.2Office of the Law Revision Counsel. 26 U.S. Code 2703 Section 2704 targets restrictions on liquidation rights in family-controlled entities: if a restriction effectively prevents liquidation and the family can remove it after the transfer, the IRS disregards it when valuing the transferred interest.3Office of the Law Revision Counsel. 26 USC 2704 Restrictions written purely to inflate discounts will be thrown out. Restrictions that serve a real business purpose and mirror what unrelated parties would agree to will hold.
Getting an Appraisal That Will Stand
Claiming a discount requires a qualified appraisal by someone with expertise in the specific type of asset the LLC holds. The appraiser must analyze the operating agreement, the nature of the assets, comparable transactions, and the specific minority interest being transferred. Getting this appraisal before you file is not optional if you want the discount to survive a challenge.
Freezing Future Appreciation Outside Your Estate
Transferring LLC interests today locks in today’s value for gift tax purposes. All growth after the transfer date belongs to the recipients and stays outside the donor’s taxable estate. That is where the real leverage lives for assets with high appreciation potential: developing real estate, early-stage businesses, or long-horizon investment portfolios.
The federal estate tax applies a top rate of 40% to assets above the exemption at death.4Internal Revenue Service. Estate Tax If an interest worth $2 million today grows to $8 million by the time the donor dies, the $6 million in appreciation avoids estate tax entirely, because it already belongs to the heirs. At 40%, that’s $2.4 million in savings on the appreciation alone, before counting any valuation discount applied when the original gift was made.
The strategy works best combined with the discounts above. You gift a discounted interest early, use less of your lifetime exemption than the underlying asset value, and all future growth compounds tax-free in the next generation’s hands. You need to file Form 709 for the year of the transfer and attach the qualified appraisal documenting value on the gift date.5Internal Revenue Service. Instructions for Form 709
Pass-Through Taxation and Income Shifting
The IRS treats a multi-member LLC as a partnership for federal income tax purposes unless it elects corporate treatment.6Internal Revenue Service. Limited Liability Company (LLC) A single-member LLC is a disregarded entity and its owner reports everything on their personal return. Either way, there’s no entity-level federal income tax, which avoids the double taxation that hits C corporations.
Once heirs hold membership interests, income flows to them based on their percentages. If a parent in the top bracket gifts 40% of an LLC generating $200,000 in annual rental income to two adult children, each child reports $40,000 on their own return. If the children sit in lower brackets, the family’s combined tax bill drops. The parent’s taxable income shrinks at the same time, which slows the growth of the estate exposed to tax at death.
Distributions must follow the allocation rules in the operating agreement, and those allocations need to reflect actual economic arrangements rather than tax-motivated assignments. The IRS can reallocate income under its partnership anti-abuse rules if distributions don’t match ownership percentages without a legitimate business justification.
Where the Kiddie Tax Cuts Off the Strategy
Shifting income to minor children or full-time students under 24 runs into a federal backstop. For 2026, a child’s first $1,350 in unearned income is tax-free, the next $1,350 is taxed at the child’s rate, and anything above $2,700 is taxed at the parent’s marginal rate. Unearned income includes the LLC distributions, rental income, and investment returns that flow to the child’s share. Bracket arbitrage on large distributions to young family members effectively disappears. The income-shifting benefit shows up primarily when the recipients are adult children or other family members who file independently and sit in lower brackets.
Step-Up in Basis and the Section 754 Election
When someone inherits an LLC interest, the tax basis of that interest resets to fair market value on the date of death. This step-up eliminates all unrealized capital gains that accumulated during the decedent’s lifetime.7Internal Revenue Service. Gifts and Inheritances If the original member put in $500,000 and the interest is worth $3 million at death, the heir’s basis becomes $3 million. Selling immediately for $3 million triggers zero capital gains tax.
There’s a catch. The step-up applies to the heir’s outside basis, meaning the value of their interest in the LLC. The LLC’s own books still show the original cost basis for its assets. If the LLC sells a property, the gain on the LLC’s return can be far higher than the heir’s stepped-up basis suggests, and the heir ends up paying tax on gains the step-up should have wiped out.
The correction is a Section 754 election. When the LLC files it, the internal basis of its assets adjusts to match the heir’s stepped-up outside basis.8Internal Revenue Service. FAQs for IRC Sec. 754 Election and Revocation The election is made by attaching a statement to the LLC’s tax return for the year the death or transfer occurs, and it must include the partnership’s name, address, and a declaration that the partnership elects under Section 754.9Office of the Law Revision Counsel. 26 U.S. Code 754 Once made, it applies to all future distributions and transfers and cannot be revoked without IRS permission. Miss the deadline and the heir can face tax on phantom gains that the step-up was supposed to eliminate.
Charging Order Protection
An LLC also offers asset protection that other structures don’t. If a creditor obtains a judgment against an individual member, the creditor’s remedy in most states is limited to a charging order. That gives the creditor a lien on distributions the member would otherwise receive. It does not let the creditor seize LLC assets, become a member, vote on company decisions, or force a liquidation.
In a family LLC where the managing members control the timing and amount of distributions, this is a practical deterrent. The creditor waits in line for distributions that may never come. Many states treat the charging order as the exclusive remedy available to a judgment creditor of a member, which means the creditor cannot reach the LLC’s underlying real estate or investment accounts. A lawsuit against one heir does not jeopardize the family’s assets held inside the entity.
How the IRS Pulls LLC Assets Back Into the Estate
Every advantage above disappears if the IRS successfully argues that the LLC’s assets belong in the donor’s taxable estate. Section 2036 is the statute the IRS reaches for most often. If a donor transfers assets into an LLC but retains “possession or enjoyment” of those assets, or keeps the right to designate who benefits from them, the full value of those assets gets pulled into the donor’s estate at death, as if the transfer never happened.10Office of the Law Revision Counsel. 26 U.S. Code 2036
The most common trigger is continuing to use LLC-owned property personally. Moving the family home into the LLC and then living there rent-free is a textbook example. Courts treat that as retaining enjoyment of the transferred property. The same applies when the LLC pays a member’s personal expenses like health care costs or insurance premiums. Those arrangements signal that the donor never truly gave up the economic benefit of the assets.
The escape valve is the “bona fide sale for adequate and full consideration” exception, and courts have added a gloss: the transfer must also serve a legitimate nontax business purpose. Consolidating family asset management, protecting assets from creditors, training the next generation, and facilitating orderly succession all qualify. The purpose has to be real and documented, not manufactured after the fact.
Formalities That Keep the LLC Intact
Running the LLC as a genuine entity separate from personal finances is what keeps Section 2036 at bay. The operational requirements aren’t complicated, but skipping them is the most common reason family LLCs fail under scrutiny:
- Keep separate accounts. The LLC needs its own bank account, and all entity income and expenses should flow through it. Never commingle personal and LLC funds.
- Charge fair value on any use of LLC property by a member, and pay market rates for any services the LLC provides to a member.
- Retain enough personal assets outside the LLC to cover living expenses. Transferring everything in and then depending on LLC funds for personal needs is a red flag courts have repeatedly cited.
- Make distributions pro rata based on ownership percentages, not personal need.
- Document properly. Hold meetings, keep minutes, maintain a separate tax identification number, file separate returns, and hold title to assets in the entity’s name.
An LLC that exists only on paper, with the donor still treating the assets as their own, will be treated by the IRS as exactly what it is: a transfer in name only.
Assets That Don’t Belong in a Family LLC
Not every asset fits the structure. S corporation stock is the most important exclusion. The IRS limits S corporation shareholders to individuals, certain trusts, and estates. Because an LLC is classified as either a partnership or a corporation for tax purposes, it cannot hold S corporation shares without terminating the S election.11Internal Revenue Service. S Corporations Losing S status forces the company into C corporation taxation and triggers entity-level tax on future earnings.
Retirement accounts like IRAs and 401(k)s also can’t be moved into an LLC without triggering a taxable distribution. Their tax-deferred structure would be destroyed by the transfer. Personal-use assets like a primary residence are technically eligible but create the Section 2036 problems above unless the member pays fair market rent, which usually defeats the purpose. The best candidates are investment real estate, marketable securities, operating business interests, and other income-producing assets where the entity can point to a genuine business reason for holding them.
Reporting the Transfers to Lock in the Discounts
Any gift of an LLC interest should be reported on Form 709 when you’re claiming a valuation discount, even one that falls within the $19,000 annual exclusion. The statute of limitations on revaluing a gift doesn’t start until the gift is “adequately disclosed” on a filed return.5Internal Revenue Service. Instructions for Form 709 Adequate disclosure means a detailed description of the method used to determine fair market value, all financial data relied on, every restriction considered, and a specific description of the discounts claimed. It also means disclosing the fair market value of 100% of the entity without discounts, the pro rata portion transferred, and the reported value of the transferred interest.12GovInfo. Treasury Regulation 301.6501(c)-1
Filing Form 709 with those details starts a three-year window during which the IRS can challenge the reported value. Without adequate disclosure, no limitations period runs at all. Families who transfer LLC interests for years and never file Form 709 can find decades later that every transfer is still open to audit. The filing costs nothing beyond professional preparation, and it is the single most important step in protecting the discounts you’ve claimed.
