Family Limited Partnership (FLP) — Valuation Discounts and Estate Tax Reduction

Executive Summary: The Power of the FLP in 2026

The Family Limited Partnership (FLP) remains one of the most sophisticated and effective tools in the estate planner's arsenal for high-net-worth families. By leveraging the principles of valuation discounts—specifically the Lack of Control (DLOC) and Lack of Marketability (DLOM)—taxpayers can transfer significant wealth to the next generation at a fraction of the underlying asset value. However, as of 2026, the IRS has intensified its scrutiny of these entities, primarily through the lens of IRC §2036. This guide provides a practitioner-grade analysis of FLP mechanics, valuation theory, and the rigorous compliance standards required to withstand an IRS audit.

Statutory Authority and Regulatory Framework

The foundation of FLP planning rests on several key sections of the Internal Revenue Code and established Treasury Regulations. Practitioners must be intimately familiar with these authorities to ensure the structural integrity of the partnership:

• IRC §2512: Governs the valuation of gifts. The "willing buyer-willing seller" test, as defined in Treas. Reg. §25.2512-1, is the standard for determining fair market value.
• IRC §2036(a)(1) and (a)(2): The primary weapons used by the IRS to pull FLP assets back into a decedent's gross estate. §2036(a)(1) focuses on the "possession or enjoyment" of the property, while §2036(a)(2) targets the "right to designate" who enjoys the property.
• IRC §2703: Addresses the effect of certain rights and restrictions on valuation, often used by the IRS to argue that partnership restrictions should be ignored for valuation purposes.
• IRC §2704: Deals with the treatment of certain lapsing rights and restrictions, particularly in the context of family-controlled entities.

Valuation Discount Theory: DLOC and DLOM

The core tax benefit of an FLP is the ability to value a transferred interest at less than its pro-rata share of the underlying net asset value (NAV). This is justified by two primary economic factors:

1. Discount for Lack of Control (DLOC)

The DLOC reflects the fact that a minority interest holder (a limited partner) cannot compel distributions, elect management, force liquidation, or dictate investment strategy. In the eyes of a "willing buyer," such an interest is significantly less valuable than the underlying assets because the buyer has no say in how those assets are managed. Typical DLOC ranges for FLPs holding diversified portfolios or real estate are 10%–25%.

2. Discount for Lack of Marketability (DLOM)

The DLOM reflects the difficulty of selling a private partnership interest compared to a publicly traded security. There is no ready market for FLP interests, and partnership agreements typically contain stringent restrictions on transfer to third parties. A buyer would demand a significant price reduction to compensate for the lack of liquidity. Typical DLOM ranges are 15%–35%.

The "Bona Fide Sale" Exception and Bongard

To escape the reach of §2036, a transfer to an FLP must meet the "bona fide sale for an adequate and full consideration" exception. As established in the landmark case Estate of Bongard v. Commissioner, 124 T.C. 95 (2005), this requires a "legitimate and significant non-tax reason" for creating the partnership. The Tax Court has consistently held that if the primary motive is tax avoidance, the exception does not apply.

Legitimate non-tax reasons recognized by courts include:

• Centralized Management: Consolidating family assets under a single management structure to achieve economies of scale and consistent investment policy.
• Asset Protection: Protecting family wealth from potential creditors, future ex-spouses, and frivolous lawsuits.
• Succession Planning: Providing a vehicle for the orderly transition of family business leadership to the next generation.
• Avoiding Ancillary Probate: Holding out-of-state real estate in an FLP to avoid the cost and complexity of multiple probate proceedings.

Detailed Implementation Guide: Step-by-Step

Successful FLP implementation requires meticulous attention to detail. A single procedural lapse can provide the IRS with the opening needed to disqualify the entire structure.

Real Numbers Example: The Miller Family (2026)

To illustrate the "pure power" of the FLP, consider the following scenario for a high-net-worth client in 2026.

Client Profile: The Miller Family has a $25,000,000 estate. They wish to transfer a $10,000,000 diversified investment portfolio to their three children.

Structure: Parents form "Miller Family Holdings, LP." Parents serve as General Partners (1% interest). They contribute the $10,000,000 portfolio and receive a 99% Limited Partnership interest.

Tax Impact: By gifting the 99% LP interest, the Millers have removed $10,000,000 of asset value from their estate while only using $6,375,000 of their lifetime gift tax exemption. At a 40% estate tax rate, this strategy creates an immediate $1,450,000 in projected tax savings ($3,625,000 discount x 40%). Furthermore, all future appreciation on the $10,000,000 portfolio now occurs outside of the parents' taxable estate.

State Applicability and Specific Considerations

While the FLP is a federal tax strategy, state laws play a critical role in its effectiveness and implementation:

• California: Practitioners must navigate Proposition 19. Transferring real property to an FLP and then gifting interests can trigger a property tax reassessment unless carefully structured. Furthermore, CA has aggressive "step transaction" rules for property tax purposes.
• Florida and Texas: These states offer some of the strongest asset protection statutes for limited partnerships, making them ideal jurisdictions for FLP formation even for out-of-state residents (subject to nexus and "doing business" rules).
• New York: With a state estate tax exemption of $6.94 million in 2026 and a "cliff" that taxes the entire estate if it exceeds the exemption by more than 5%, FLP discounts are essential for NY residents to stay below the threshold.
• Ancillary Probate: For a client living in a high-tax state like New Jersey who owns vacation property in South Carolina, placing the SC property in an FLP converts it from "real property" to "intangible personal property," avoiding SC probate.

Common Mistakes and Audit Triggers

The IRS "Audit Technique Guide" for FLPs highlights several red flags that practitioners must avoid:

1. Commingling of Funds: Using the FLP bank account to pay for the GP's personal groceries, mortgage, or country club dues. This is the #1 reason FLPs fail under §2036(a)(1).
2. Deathbed Transfers: Forming the FLP and gifting interests within weeks or months of death. In Estate of Fields v. Commissioner (2024), the court disregarded an FLP formed less than a month before death where the decedent lacked a substantial non-tax purpose.
3. Failure to Maintain Records: Not holding annual meetings, not keeping minutes, and failing to file annual partnership tax returns (Form 1065). If you don't treat it like a business, the IRS won't either.
4. Disproportionate Distributions: Making distributions to the GP to cover personal taxes or expenses without making pro-rata distributions to the LPs.
5. Funding with 100% of Assets: If the client contributes all their liquid assets to the FLP and has no way to pay their bills without FLP distributions, the IRS will argue there was an "implied agreement" for retained enjoyment under §2036.
