Family limited partnerships: the asset protection and estate planning structure, the valuation discounts for gift and estate tax, the IRS scrutiny for sham entities, and the coordination with §754 and §2036

A family limited partnership (FLP) is one of the most powerful combined asset-protection and estate-planning structures available, and one of the most scrutinized by the IRS. The structure is straightforward: a limited partnership where the family's senior generation controls the assets as general partner, and the younger generation holds economic ownership as limited partners. The partnership form provides asset protection (creditors of a limited partner generally cannot reach the partnership's assets), and the transfer of limited partnership interests to the younger generation can be done at a substantial discount for gift and estate tax purposes.

The valuation discounts are the primary tax motivation. When a parent gives a limited partnership interest to a child or to a trust for a child's benefit, the interest is valued for gift tax purposes at less than the proportional value of the underlying assets, because the limited partner has no control over the partnership's operations and cannot easily sell the interest on the open market. Discounts of 15-40% (combining the minority interest discount and the lack-of-marketability discount) are common in practice, which means a family can transfer substantially more wealth within the gift tax exemption than it could by transferring the underlying assets directly.

The IRS knows this, and it audits FLPs aggressively. The line between a legitimate FLP (one with a real business purpose, proper formalities, and a genuine transfer of economic ownership) and a sham FLP (one created solely to generate discounts without any real change in economic substance) is the central battleground.

How the structure works

A family limited partnership typically involves three categories of participants:

General partner (GP). The GP controls the partnership's operations, investments, and distributions. The GP is usually the senior-generation family member, a family-owned LLC, or a trust. The GP holds a small ownership percentage (typically 1-2%) but retains full management authority.

Limited partners (LPs). The LPs hold the economic ownership of the partnership (typically 98-99%) but have no management authority and cannot compel distributions, sell assets, or direct the partnership's operations. The LPs are typically the younger-generation family members or trusts established for their benefit.

The partnership itself. The FLP is a state-law limited partnership, formed under the applicable state's Revised Uniform Limited Partnership Act (RULPA) or equivalent. It holds the family's assets (real estate, investment portfolio, operating business interests, family farm, or other wealth) and operates under a partnership agreement that governs distributions, management, transferability, and dissolution.

The GP makes a gift of limited partnership interests to the LPs (or to trusts for the LPs' benefit). The gift is valued for gift tax purposes at a discount from the proportional value of the underlying assets, because the limited partnership interest carries restrictions on transferability and no control over management.

The valuation discounts

The discounts are the tax planning engine of the FLP. Two distinct discounts apply:

Minority interest discount (also called the lack-of-control discount). A limited partner has no voting rights, no management authority, and no ability to compel distributions or liquidate the partnership. An outside buyer would pay less for a passive, non-controlling interest than for a proportional share of the underlying assets. The minority interest discount reflects this reduction.

Lack-of-marketability discount. A limited partnership interest is not publicly traded. There is no ready market for it. An outside buyer would pay less for an illiquid, non-tradeable interest than for a liquid, publicly tradeable security. The lack-of-marketability discount reflects this reduction.

Combined, the two discounts typically range from 15% to 40% of the proportional asset value, depending on the specific facts (the type of assets held, the partnership agreement restrictions, the size of the interest, the existence of a buy-sell provision, and the appraiser's methodology).

For a parent with $10 million in assets who transfers a 40% limited partnership interest to a child, the proportional asset value of the interest is $4 million. With a combined 30% discount, the gift tax value is $2.8 million, saving $1.2 million in gift/estate tax value. Over multiple gifts and multiple generations, the cumulative discount can shelter millions of dollars from transfer tax.

The asset protection component

The asset protection function of the FLP is separate from the estate planning function, and both can operate simultaneously.

Under most states' limited partnership statutes, a creditor of a limited partner who obtains a judgment against the partner cannot seize the partnership's assets or force a liquidation. The creditor's remedy is limited to a "charging order," which entitles the creditor to receive any distributions that would otherwise go to the debtor limited partner. The creditor cannot vote, participate in management, compel distributions, or reach the partnership's underlying assets.

Because the GP controls distributions, the GP can choose not to make distributions, which means the creditor with a charging order may receive nothing (while still potentially owing tax on the partnership income allocated to the debtor partner's account, a feature sometimes called the "reverse vesting" or "poison pill" effect of charging orders).

The asset protection is not absolute. It does not protect against fraudulent transfer claims (transferring assets to an FLP after a claim has arisen or is reasonably anticipated is a fraudulent transfer under most states' Uniform Voidable Transactions Act). It does not protect against the IRS (federal tax liens attach to the taxpayer's partnership interest). And it is weaker in states that allow creditors to foreclose on partnership interests rather than merely obtaining a charging order.

The protection works best when the FLP is formed before any claims arise, when the FLP has a legitimate business purpose beyond asset protection, and when the formalities are respected (the partnership agreement is followed, distributions are made in accordance with the agreement, and the partnership maintains separate books and accounts).

The IRS scrutiny

The IRS has challenged FLPs for decades, and the case law is substantial. The two primary attack theories:

§2036 inclusion. Under IRC §2036, if the decedent transferred property to the FLP but retained the right to use, possess, or enjoy the property (or the right to income from the property) during their lifetime, the transferred property is included in the decedent's gross estate at full value, eliminating the discount.

The §2036 attack succeeds when the senior generation transferred personal-use assets (the family home, a personal investment account) to the FLP but continued to use them as before, without paying rent or otherwise respecting the partnership's ownership. The courts have consistently held that when the transferor's relationship to the assets doesn't meaningfully change after the transfer (they continue to live in the house, spend the investment income, commingle funds), §2036 applies and the assets are pulled back into the estate at full, undiscounted value.

Sham entity / lack of business purpose. The IRS argues that the FLP was formed solely for tax avoidance and has no legitimate non-tax business purpose. A sham FLP is one that was created on a deathbed (literally days before death, in some litigated cases), was funded with personal-use assets rather than business or investment assets, did not observe partnership formalities (no separate books, no arm's-length transactions, commingled funds), and had no purpose beyond generating discounts.

The Tax Court has developed a multi-factor test (drawing from cases like Estate of Bongard, Estate of Strangi, and Estate of Turner) that examines whether the partnership was created and operated with a legitimate and significant non-tax purpose. Legitimate purposes that courts have accepted include centralized management of family investments, facilitating intergenerational transfers with retained management, protecting assets from creditors, and operating an actual business.

What makes an FLP defensible

The case law defines a spectrum from "clearly legitimate" to "clearly a sham." The defensible FLP:

Is formed well in advance of death or any anticipated transfer tax event (not on a deathbed).

Is funded with business or investment assets, not personal-use assets (the family home, personal checking accounts, and similar assets should stay out of the FLP).

Has a written partnership agreement that is followed in practice (distributions are made according to the agreement, capital accounts are maintained, meetings are held, records are kept).

Maintains separate books and accounts (the FLP's bank accounts are not commingled with the GP's personal accounts).

Has a legitimate non-tax business purpose (centralized investment management, business operations, asset protection from actual or reasonably anticipated risks).

Does not allow the senior generation to use the partnership's assets for personal purposes without arm's-length compensation (no rent-free use of the FLP's real estate, no personal spending from the FLP's accounts).

An FLP that meets these criteria can defend its discounts on audit and in court. An FLP that fails multiple criteria is vulnerable to both the §2036 attack and the sham-entity challenge.

Coordination with other provisions

The FLP framework interacts with several other Halstonberg small business provisions:

§754 election and §743(b) basis adjustment applies to FLPs: when a limited partnership interest is transferred at death, the §754 election allows the partnership to step up the basis of its assets to reflect the heir's stepped-up outside basis. For FLPs holding appreciated assets, the §754 election is critical to avoid phantom gain.

Partnership tax fundamentals cover the basic tax mechanics that apply to FLPs, including the pass-through of income and loss, the allocation rules, and the distribution rules.

Business succession planning often involves FLPs as the vehicle for intergenerational transfer of family business interests.

Asset protection planning covers the broader asset protection landscape, of which FLPs are one tool.

§721 partnership formation governs the tax-free contribution of assets to the FLP at formation.

Practical guidance

For families considering an FLP:

Form the FLP well in advance of any anticipated transfer. Deathbed FLPs are the most vulnerable to IRS challenge; FLPs formed years before any transfer event are the most defensible.

Fund the FLP with investment or business assets, not personal-use assets. Keep the family home, personal vehicles, and personal checking accounts out of the FLP.

Maintain rigorous formalities. Separate bank accounts, maintained books and records, partnership meetings (or written consents), and distributions made according to the partnership agreement. The formalities are the evidence that the partnership is real.

Ensure a legitimate non-tax purpose. Centralized investment management, asset protection, and business operations are all accepted purposes. Document the purpose at formation and maintain it throughout the partnership's existence.

Do not allow the senior generation to use partnership assets for personal purposes without arm's-length compensation. Rent-free use of FLP real estate and personal spending from FLP accounts are the most common §2036 triggers.

Obtain a qualified, independent appraisal of the limited partnership interests for any gift. The valuation discounts must be supported by an appraisal that uses accepted methodologies and accounts for the specific restrictions in the partnership agreement. The IRS challenges unsupported or inflated discounts.

Consider the §754 election. For FLPs holding appreciated assets, the election ensures that the basis step-up at death applies to the partnership's inside basis, preventing phantom gain for the heirs.

Coordinate with estate planning counsel, tax counsel, and the independent appraiser. The FLP structure involves partnership law, tax law, estate planning law, and valuation; the interdisciplinary nature of the planning requires coordination among advisors.

The FLP remains one of the most effective tools for families seeking to transfer wealth with reduced transfer tax and to protect family assets from creditor claims. The IRS's scrutiny of FLPs is real and well-established, but the case law also clearly establishes that properly structured and maintained FLPs produce legitimate, defensible valuation discounts. The quality of the planning, the reality of the business purpose, and the rigor of the formalities determine whether the FLP survives IRS challenge.
