Family Limited Partnership (FLP) & Family LLC — Estate Planning with Valuation Discounts

A family limited partnership (FLP) or family LLC lets you transfer significant wealth to heirs at a reduced gift-tax value. The core mechanic: a minority interest in a closely-held entity is worth less than the pro-rata share of the underlying assets — the holder can't force distributions, sell the assets, or control management. That discount, verified by a qualified appraiser, reduces the taxable gift or estate value, often by 25–45% combined.

How valuation discounts work

FLP and family LLC interests trade at a discount to net asset value (NAV) because limited partners and minority members lack two things that control investors have:

1. Control — minority interest discount. A limited partner can't force liquidation, redirect investments, or override the general partner. Appraisers apply a minority interest discount — typically 15–35% — reflecting the lack of control rights, supported by empirical studies of arm's-length sales of minority interests in closely-held entities.
2. Marketability — DLOM (discount for lack of marketability). LP interests aren't publicly traded; there's no ready buyer. The resulting illiquidity warrants a separate discount — typically 10–30% — applied in addition to the minority discount.

The two discounts compound multiplicatively. A 25% minority discount plus a 20% DLOM yields a combined discount of about 40%: (1 − 0.25) × (1 − 0.20) = 0.60, meaning the taxable gift value is 60% of the pro-rata NAV.

What assets work best in an FLP

Not every asset belongs in an FLP. The best candidates are ones that support a legitimate business purpose and carry defensible economic discounts:

• Investment portfolios. The most common. A managed portfolio held in an FLP can support discounts if the entity has a genuine investment policy, regular management decisions, and documented governance.
• Commercial real estate. Multi-property portfolios and multi-family buildings work well. A single-family rental with minimal management activity is harder to defend as a bona fide business.
• Closely-held operating businesses. FLP/LLC interests in an existing operating company often carry natural minority discounts; layering an estate planning structure can extend the gifting runway. Coordinate with buy-sell agreement planning.
• Mineral rights and timberland. Concentrated illiquid assets where a marketability discount is economically self-evident.

Assets that don't work: cash and personal checking accounts, personal-use real estate (use a QPRT instead), IRAs and retirement accounts (can't be contributed to an entity), and life insurance (ownership structure conflicts with ILIT rules).

The bona fide business purpose requirement

The IRS scrutinizes every FLP. The legal hook is IRC §2036, which can pull FLP assets back into the taxable estate if the decedent retained the right to income or effective control — and the structure wasn't a genuine business arrangement. Courts weigh three factors when deciding whether the §2036 bona fide sale exception applies:

1. Legitimate, non-tax business purpose. Credible purposes include: centralized investment management, creditor protection for limited partners, family governance and succession, business continuity. A factual record showing only "save estate taxes" as the motivation significantly weakens this prong.
2. Bona fide sale for adequate consideration. Under IRC §2703, transfers at less than fair market value can be disregarded unless the arrangement is a genuine business arrangement, is not a testamentary substitute, and is comparable to what unrelated parties would agree to — the three-pronged bona fide sale exception.
3. Formalities respected throughout. Separate bank accounts, documented investment decisions, regular partnership meetings, and complete separation from personal finances. Courts have disregarded FLPs when grantors treated partnership assets as personal funds.

IRS audit risk: IRC §2036 inclusion

If the IRS successfully argues §2036(a)(1) (retained right to income from the transferred property) or §2036(a)(2) (retained power to designate who enjoys the property), the FLP assets are pulled back into the taxable estate at full fair market value — undoing the discount strategy. Common §2036 red flags:

• Grantor paid personal expenses from partnership accounts
• All partnership distributions flowed directly to the grantor's personal accounts to cover living expenses
• Partnership held assets passively with no investment management activity
• Transfer was made within months of death with no prior business history
• Operating agreement gave the general partner effectively unlimited discretion without oversight from an independent trustee or advisory committee

Defensible FLPs document investment decisions, hold periodic partnership meetings, maintain complete books, and operate with a separation between personal and partnership finances that a third party could verify.

FLP vs family LLC — which structure fits better

For most estate planning purposes, the two structures produce similar valuation discount results. The choice often turns on state law, existing entity structures, and whether the family has operating businesses (FLP) vs. a pure investment mandate (LLC).

Post-OBBBA context: why FLPs still matter with the $15M exemption

The One Big Beautiful Bill Act (July 2025) permanently set the federal estate and gift tax exemption at $15M per individual ($30M per married couple with portability). The previously-scheduled 2026 sunset to $7M is gone. But FLPs remain valuable for three distinct reasons:

1. Estates above $15M. A family with $25M in net worth still faces 40% federal estate tax on roughly $10M. Transferring $7M in LP interests at a 35% combined discount moves $10M in economic value out of the estate while using only $6.5M of exemption — $3.5M of exemption freed for other uses or future growth.
2. State estate taxes. Twelve states plus DC impose estate taxes at exemptions far below the federal level — Oregon at $1M, Massachusetts at $2M, Washington at $2.2M. FLP valuation discounts reduce the state-taxable estate in these jurisdictions independently of the federal exemption.
3. Asset protection. Charging order protection means a creditor who wins a judgment against a limited partner can only receive distributions if and when the general partner makes them — they can't seize partnership assets or force a sale. For professionals and business owners with liability exposure, this is often the primary driver, with estate tax savings as the secondary benefit.

How FLPs integrate with gifting strategy

The FLP and annual exclusion gifting work together as a multi-year transfer plan:

• Form the FLP and contribute assets. You initially hold 100% of LP interests (plus the GP interest at roughly 1%)
• Gift LP interests to children or grandchildren, valued by the appraiser at the discounted price — not NAV
• Use the $19,000/year annual exclusion per donee ($38,000/year with gift-splitting)⁴ to transfer LP interests without touching lifetime exemption — provided the LP interests are structured as present-interest transfers
• Layer in a dynasty trust as the ultimate LP interest holder — GST exemption allocation means those interests pass free of GST at each generation's death
• Combine with GRAT: contribute LP interests to a GRAT; if the interests appreciate past the §7520 hurdle rate, excess passes to heirs at no exemption cost

5 common FLP mistakes

1. Funding during a health crisis. Transferring the family estate into an FLP when the grantor is terminally ill or in serious decline signals testamentary intent. Tax Court has repeatedly ruled against FLPs formed in the final months of a grantor's life. Fund early.
2. Commingling assets. A single personal expense paid from the partnership account can be used by the IRS as evidence that the grantor retained the right to income under §2036. Maintain strict separation.
3. No documented business activity. A passive holding vehicle with no investment decisions, no minutes, and no management activity is difficult to defend as a bona fide business. Document rebalancing decisions, distribution analyses, and any investment policy changes.
4. Skipping the qualified appraisal. The discount must be supported by a qualified appraisal at each gifting event. An unsupported discount claim is an accuracy-related penalty risk. Appraiser cost typically runs $5K–$20K annually — a fraction of the estate tax benefit on a significant transfer.
5. Gifting non-present-interest LP interests. For the annual exclusion to apply, the LP gift must be a present interest — the donee has immediate enjoyment rights. Standard LP interests often restrict transfers and withdrawals, making them future interests. Many FLPs address this with withdrawal rights (Crummey notices) in the operating agreement. Without that drafting, annual exclusion gifts may be disallowed on audit.
