Family Limited Partnership (FLP): Valuation Discounts for HNW Estate Planning

A family limited partnership restructures how assets are owned — and how they're valued for gift and estate tax purposes. The senior generation forms an FLP, transfers investment assets or real estate to it, retains the general partner interest (and management control), and gifts limited partner interests to heirs over time. Those LP interests are taxable at a discounted value — typically 20–40% below the underlying asset value — because a minority LP interest has no voting control and cannot be freely sold. With the OBBBA's permanent $15M federal exemption, FLPs are most powerful for estates above $30M, for families with state estate tax exposure, and for transferring illiquid or concentrated positions over many years using leveraged annual exclusion gifts.

How a family limited partnership is structured

An FLP is a limited partnership formed under state law — typically Delaware or Nevada for favorable charging-order protection — with two classes of interest: general partner (GP) and limited partner (LP).

• General partner. The senior generation (or a family LLC they control) holds the GP interest — typically 1–2% of economic value. The GP makes all investment and management decisions, controls distributions, and is personally liable for partnership obligations. Retaining the GP interest is what preserves control while you transfer LP interests to heirs.
• Limited partner. LP interests receive their pro-rata share of economic returns — income, appreciation, distributions — but carry no management rights, no ability to force a liquidation, and no right to transfer without GP consent. These restrictions are the legal foundation for the valuation discount.

The typical structure: parents form the FLP, contribute a $5M investment portfolio or real estate holding, retain the 1% GP interest plus an initial LP position, and gradually gift LP interests to children or irrevocable trusts each year — using annual exclusion gifts and, when needed, taxable lifetime gifts against the $15M exemption.¹

Valuation discounts — the core tax benefit

When you gift an LP interest in an FLP, its value for gift tax purposes is not the LP's pro-rata share of underlying assets. Under IRC § 2512 and the longstanding valuation standard of Rev. Rul. 59-60, fair market value equals what a hypothetical willing buyer would pay a hypothetical willing seller — neither under compulsion.²

A rational buyer discounts an LP interest for two reasons:

1. Minority interest discount. An LP interest confers no control over the partnership, its investments, or its distributions. A 30% LP stake cannot force a sale, redirect the investment strategy, or demand a payout. This lack of control justifies a discount — typically 15–30% — relative to the LP's pro-rata share of underlying net asset value.
2. Discount for lack of marketability (DLOM). Unlike publicly traded stock, an FLP interest has no liquid secondary market. The partnership agreement restricts transfers — LP interests typically require GP consent to assign. This illiquidity adds a second discount — typically 10–25% — layered on top of the minority discount.

The two discounts compound. At 20% minority discount and 15% DLOM, the combined reduction is approximately 32% (1 − (0.80 × 0.85) = 0.32). In practice, qualified appraisers supporting FLP transfers typically document combined discounts of 25–40%, with the exact figure depending on the asset type inside the FLP and the specific transfer restrictions in the partnership agreement.²

Annual exclusion leverage

The valuation discount multiplies the efficiency of annual exclusion gifting. In 2026, each donor can give $19,000 per recipient without using any lifetime exemption or owing gift tax.³ With an FLP at a 30% discount, a $19,000 gift of LP interests represents $27,143 in underlying FLP asset value — a 43% leverage factor on the annual exclusion.

A couple with three adult children can gift $19,000 per child from each spouse ($114,000 total taxable gift value per year). At a 30% discount, that moves $162,857 of underlying FLP asset value out of their estate annually — without touching the $15M lifetime exemption. Over 10 years: $1.63M of FLP asset value removed on annual exclusions alone.

For families with illiquid assets — closely-held business interests, commercial real estate, minority stakes in operating companies — the FLP consolidates management into a single entity and creates a uniform security (LP units) that can be systematically gifted at a defined discount. Gifting fractional interests in real estate or a business directly is legally cumbersome; gifting LP units is straightforward once the FLP is funded.

The business purpose requirement — the critical legal gate

An FLP will not survive IRS scrutiny unless it has a genuine, non-tax business purpose. Courts and the IRS consistently hold that an FLP formed solely to generate valuation discounts — with no operational rationale — is disregarded for transfer tax purposes under the step-transaction or economic substance doctrines.⁴

Business purposes courts have consistently upheld:

• Centralized investment management. Consolidating family assets into a single entity for professional management, coordinated investment policy, and unified reporting across generations.
• Asset protection. In states with strong charging-order statutes (Delaware, Nevada), an FLP limits a creditor to a charging order against future distributions — they cannot seize the LP interest or force a liquidation. This is a documented non-tax benefit.
• Business continuity planning. A formal partnership structure facilitates management succession from the founder generation to successors, with documented authority, succession provisions, and a governance framework.
• Fractional interest consolidation. When multiple family members hold inherited fractional interests in real estate or a business, an FLP prevents forced partition, enables coordinated management, and simplifies eventual sale — avoiding the deadlock and discount-on-discount problem of direct fractional ownership.

Business purpose must exist from formation — not crafted after the fact. The FLP must actually operate as a business: a written partnership agreement, a separate partnership bank account, formal capital accounts maintained under IRC § 704, annual partnership tax returns (Form 1065 with K-1s to each partner), and distributions that follow the partnership agreement rather than personal cash needs of the senior generation.

§ 2036 inclusion risk — the IRS's main attack

IRC § 2036 requires that a decedent's gross estate include any property transferred during life if the transferor retained either the right to income from the property or the right to designate who enjoys it. This is the IRS's primary weapon against FLPs that don't observe proper boundaries.⁴

The leading adverse case is Estate of Strangi v. Commissioner. Harry Strangi transferred substantially all his assets to an FLP nine months before his death, continued to pay personal expenses from FLP accounts, and the FLP paid life insurance premiums for his benefit. The Tax Court upheld § 2036 inclusion — the entire FLP was pulled back into his taxable estate, eliminating all discounts. The Fifth Circuit affirmed.⁴

By contrast, in Holman v. Commissioner, the Tax Court upheld an FLP funded with Dell stock at an approximately 26% combined discount. The key difference: the Holman FLP had a documented non-tax business purpose (asset protection for children), was funded with non-deathbed timing, respected formalities, and the transferors retained enough assets outside the FLP to fund their living expenses independently.

FLP vs. direct gifting vs. irrevocable trust

When FLP makes sense for HNW families

Estates above $30M. The OBBBA permanently raised the federal estate, gift, and GST exemption to $15M per person — $30M for a married couple using portability.¹ FLPs do their most powerful transfer-tax work for estates that will exceed the combined threshold, or for families anticipating a large liquidity event (business sale, significant real estate gain, equity compensation vest) that pushes them over.

State estate tax exposure. Seventeen states impose estate taxes below the $15M federal floor. Oregon taxes estates above $1M at rates up to 16%. Massachusetts kicks in at $2M. New York at $7.35M — with a "cliff" that taxes the entire estate at the marginal rate, not just the excess. For households in these states with $5M–$15M, FLP transfers reduce the state-taxable estate and can be the primary economic justification for the strategy.

Illiquid asset concentrations. A family with a $10M commercial real estate portfolio held in multiple LLCs, or a closely-held business interest worth $8M, cannot easily gift fractional interests directly. The FLP consolidates management, creates uniform LP units, and enables systematic annual transfers — all backed by a supportable appraisal at each gift.

Multi-decade transfer programs. The FLP structure is built for gradual, sustained wealth transfer over 10–20 years. Families intending to gift $100K–$200K per year across multiple recipients benefit from having the discounted vehicle set up once, appraised annually, and used systematically — rather than engineering a new transaction each year.

FLPs are generally not the right tool for households under $5M or with entirely liquid assets. At smaller scale, direct gifts, 529 superfunding, and GRAT structures typically provide equivalent leverage with lower setup cost and ongoing complexity.

What a proper FLP implementation involves

A compliant FLP requires all of the following:

1. Partnership agreement. Drafted by estate planning counsel, specifying GP/LP allocations, the distribution waterfall, transfer restrictions, withdrawal limitations, and dissolution provisions.
2. State filing. Certificate of limited partnership in your chosen jurisdiction (Delaware and Nevada have the most favorable charging-order statutes).
3. Proper funding. Titled assets must actually be transferred to the FLP — stock re-registered, real estate deeded, bank accounts re-titled. Paper transfers only invite § 2036 attack.
4. Annual qualified appraisal. Each LP gift must be supported by a qualified appraisal documenting the discount, signed by a qualified appraiser, attached to Form 709 (gift tax return). This is not optional — it's required by IRC § 6662 to avoid the 20–40% accuracy-related penalty.
5. Partnership tax filings. Annual Form 1065 with K-1s to every partner. Failure to file creates IRS inquiry triggers.
6. Ongoing formalities. The GP must actually manage the partnership — hold annual meetings, maintain minutes or written consents, keep separate accounts, and make distributions per the partnership agreement.

A fee-only wealth advisor coordinates this with your estate attorney (agreement drafting), CPA (annual filings, gift tax returns), and appraiser (annual discount documentation) — the four-specialist model. An FLP that no one monitors after formation is the single biggest § 2036 risk. See the advisory team coordination guide for how this works in practice.
