Why Your Aging Family Limited Partnership Is Becoming a Capital Gains Trap for Heirs
If your family created a Family Limited Partnership (FLP) decades ago, the primary goal was almost certainly to minimize federal estate taxes. But the tax landscape has fundamentally shifted. Under the Tax Cuts and Jobs Act of 2017, the federal estate tax exemption sits historically high through 2025, meaning very few families actually pay it. The exemption is scheduled to fall substantially after December 31, 2025, unless Congress changes the law. Even so, for many families the real financial threat today is capital gains tax. If you retain an antiquated FLP, assets originally gifted to heirs carry over their original, low purchase price. By methodically unwinding the family limited partnership, you can return those assets to the older generation's taxable estate. This strategic reversal may help your heirs capture a 'step-up in basis' under Internal Revenue Code Section 1014 at death, potentially saving millions in capital gains taxes while keeping the wealth intact.
The Case of Eleanor: A Carryover Catastrophe
Consider a common scenario unfolding quietly in modern estate administration. Eleanor’s parents successfully operated several commercial properties. In 1998, acting on sound advice for the era, they transferred these properties—originally purchased for $1 million—into a Family Limited Partnership. Over the next decade, they systematically gifted 45% of the partnership's limited units to Eleanor to freeze the size of their own taxable estate.
Today, the underlying real estate is valued at $6 million. Under the original estate plan, Eleanor’s parents accomplished their goal: moving future appreciation out of their estate. However, because she received her 45% stake as a lifetime gift, the original tax basis carried over to her. She does not reset the clock on those assets.
Eleanor sat in her CPA’s conference room on a Tuesday afternoon, staring blankly at the spreadsheet projected on the screen. She had assumed that upon her parents' eventual passing, the family could sell the portfolio and walk away clean. The accountant pointed directly to the line item representing her gifted 45% share. "Because you already own this through the partnership, you do not get a step-up in basis on this portion," he explained quietly. Her carryover basis on that 45% share was roughly $450,000—45% of the original $1 million purchase price. At a current value of approximately $2.7 million, that left a taxable gain of about $2.25 million, which could produce roughly $450,000 in federal capital gains tax at a 20% rate, before applicable state taxes. The very vehicle designed to save her family money had inadvertently transformed into a costly tax trap.
The Myth of the Estate Tax Discount
To understand why FLPs may be hazardous today, you must understand the math of the 1990s and early 2000s. At that time, an individual could only pass exactly $600,000 tax-free. Everything above that threshold was subject to federal estate tax at rates reaching 55%. Wealthy families desperately needed a discount mechanism.
By placing assets into an FLP, parents retained control as General Partners but restricted the liquidity and voting rights of the Limited Partners. Because limited units were hard to sell and held no management power, IRS appraisers allowed families to apply a "Discount for Lack of Marketability" and a "Discount for Lack of Control." A $10 million asset might only be valued at $6.5 million for tax purposes.
Under current law through 2025, the estate tax has vanished for 99% of families. The TCJA expanded the individual estate exemption to over $13.6 million in 2024, or more than $27 million for a married couple, with inflation adjustments through 2025. Unless Congress acts, the exemption is scheduled to revert to a much lower, inflation-adjusted level—roughly $5 million to $6 million per person—after 2025. Consequently, valuation discounts inside an FLP may be unnecessary for many families today and can be destructive when they reduce the value eligible for a future basis step-up. Whether unwinding is appropriate depends on the family's assets, projected exemption, state taxes, and non-tax objectives.
Holding onto a discount-driven legal entity when the estate tax may not apply can mean choosing to pay capital gains tax to avoid an estate tax you never owed. That calculation should be revisited as the law changes.
Comparing the Impact: Retaining vs. Unwinding
Families often hesitate to untangle decades of legal architecture. "If it isn't broken, don't fix it" is a common refrain. But when evaluating the capital gains on inherited real estate and family enterprises, inaction has a quantifiable cost.
The Risks of Maintaining the Status Quo
- Carryover Basis Realities: Any units gifted prior to death generally retain the donor's original basis, subject to the applicable gift-tax basis rules.
- Audit and Administration Risk: Retained FLPs can draw IRS scrutiny under Internal Revenue Code Section 2036, requiring rigorous annual administration to demonstrate that they serve legitimate business and family purposes rather than functioning solely as tax shelters.
- Structural Friction: Heirs cannot easily sell underlying properties without the required consent, causing liquidity deadlocks.
The Potential Benefits of Strategic Unwinding
- Broader Basis Reset: Returning ownership to the older generation may allow more of the assets to receive a basis adjustment at death, if the assets are included in the taxable estate under applicable law.
- Operational Simplification: May eliminate the need for future partnership returns and K-1 statements once the entity is fully liquidated.
- Clear Transfer Lines: Heirs may directly inherit specific assets rather than abstract, convoluted partnership units.
| Strategic Decision | Estate Tax Risk | Capital Gains Consequence |
|---|---|---|
| Retain antiquated FLP with prior gifts | May be minimal while the TCJA exemption remains high, but the law is scheduled to change after 2025. | Previously gifted limited units generally retain carryover basis. |
| Dissolve FLP and return assets to estate | Depends on the size and composition of the estate, applicable exemption, and state law. | May permit a broader IRC 1014 basis adjustment, subject to inclusion and other requirements. |
| Maintain FLP but ignore K-1 filings | High. IRS may challenge the arrangement and potentially pull assets back under §2036. | Penalties, interest, and litigation can overwhelm any potential tax benefits. |
Overlooked Operational Realities
Unwinding a Family Limited Partnership is an intensive administrative endeavor, not just a matter of tearing up an operating agreement. The partnership has a cost basis in the assets it holds (inside basis), while individual partners have tax bases in their ownership interests (outside basis). After decades of operations, cash flows, depreciation, and gifting, these figures may diverge substantially. A CPA must reconcile them before distributions are made.
If a family liquidates the partnership without reconciling this math, it can accidentally trigger taxable events under Internal Revenue Code Section 731, particularly when cash distributed to a partner exceeds that partner's outside basis. Depending on the facts, an appropriate Section 754 election or other basis adjustment may help, but it is not an automatic cure.
Younger generations may also need to consider upstream basis planning. This counter-intuitive strategy can involve transferring appreciated assets back to a trusted, elderly parent, potentially bringing them within the older generation’s estate through carefully drafted powers of appointment or other mechanisms. Specialized counsel must evaluate the estate, gift, income-tax, and creditor implications before implementation.
How to Unwind a Family Limited Partnership
If your legal advisors have determined that dissolution serves the family's financial interest, the execution phase requires precision. Any deviation can be interpreted by the IRS as a taxable exchange between partners.
- Conduct a Comprehensive Basis Audit: Your CPA must reconstruct the historical basis of both the partnership's physical assets and each partner's respective unit interests to identify potential tax triggers before any distributions occur.
- Evaluate a Section 754 Election if Needed: If time has created disparities between inside and outside ledgers, your accountant might recommend this election to adjust the basis of partnership property, subject to the statutory requirements and the partnership agreement.
- Draft a Unanimous or Otherwise Authorized Liquidation Agreement: The General Partners must formally convene, document the business justification for the dissolution, and obtain the approvals required by the partnership agreement and applicable state law.
- Distribute Assets Pro-Rata In-Kind Where Appropriate: To reduce the risk of triggering sudden gains, the underlying real estate, private equities, and securities may generally be distributed in proportion to ownership ratios. If a partner owns 22% of the FLP, they should generally receive a 22% undivided interest in distributed assets unless counsel approves another structure.
- File Final State and Federal Returns: Formally notify the state's Secretary of State regarding the entity's cancellation, where required, and file a final Form 1065 marked "Final Return" with the Internal Revenue Service.
Common Mistakes When Dissolving an FLP
Operational shortcuts during dissolution frequently spiral into familial conflict and tax problems. Families exhausted by administrative hurdles may attempt to barter assets or negotiate uneven swaps during the unwinding phase without first obtaining tax advice.
- Disproportionate Distributions: Handing all the real estate to one child and all the marketable securities to another, despite them holding equal partnership stakes, can create taxable exchanges or other adverse consequences unless properly structured.
- Failing to Update Successor Deeds: Terminating the state LLC or FLP without accurately recording new, updated deeds at the county clerk's office creates a broken chain of title, freezing future sales.
- Ignoring the 2026 TCJA Change: Waiting too long to authorize dissolution may expose the family to a substantially lower estate tax exemption if Congress allows the scheduled reduction to take effect after December 31, 2025.
Consider the aftermath of a poorly executed plan. Eleanor and her sibling stood in the driveway of their parents' primary commercial warehouse, locked in a bitter dispute. The brother wanted the liquid treasury bonds to expand his own business, while Eleanor intended to manage the real property for long-term yields. During dissolution, they forced their father to split the FLP unevenly to accommodate these desires. Weeks later, the IRS could view the unequal distribution as a deemed sale or other taxable exchange, potentially generating reporting obligations and tax liabilities for both siblings. An emotional shortcut created a procedural catastrophe.
The FLP Review Checklist
Evaluating your family’s exposure requires asking hard questions about the age, purpose, and utility of your legal architecture. Review this checklist with your fiduciary team:
- Does our taxable estate fall under the applicable exemption? The exemption was more than $13.6 million per person in 2024 and was scheduled to increase for inflation in 2025, but it is scheduled to fall substantially after 2025 unless Congress acts. State estate taxes may apply at lower thresholds.
- Were limited partnership shares gifted during the founder's lifetime? If yes, those specific shares generally have a low carryover basis.
- Has the underlying property highly appreciated? If the internal assets have doubled or tripled in value since the partnership's formation, capturing a basis adjustment may be important.
- Are the administrative costs eroding profits? Review annual CPA fees for filing K-1s and conducting appraisal defenses compared with the actual utility of the structure.
Cementing Your Modern Legacy Architecture
Once the FLP is dissolved, families may be left with a surge of new deeds, trust amendments, account records, appraisal documents, and revised healthcare directives. Centralizing these in an encrypted digital vault—such as Cipherwill—helps ensure that fiduciaries have immediate clarity on asset titling when it matters most.
By securely organizing updated basis documentation, revised ownership records, operating procedures, and account information, families can make the post-dissolution financial architecture easier for authorized beneficiaries and fiduciaries to understand and administer.
Frequently Asked Questions
Question: What does unwinding an FLP actually mean in legal terms?
Answer: Unwinding a family limited partnership involves formally dissolving the legal entity under state law and distributing its underlying assets directly to the partners. This process eliminates the fractional ownership limits and valuation discounts, allowing assets to return directly to the senior generation’s taxable estate for possible future basis-step-up advantages, if the applicable inclusion requirements are met.
Question: How does an FLP limit the step-up in basis at death?
Answer: When parents create an FLP and gift partnership units to their children to avoid estate taxes, those gifted units generally carry over the original tax basis. Consequently, when the parents pass away, the children already own the units and generally do not receive a basis adjustment under Internal Revenue Code Section 1014 for those units, potentially trapping substantial capital gains.
Question: Will unwinding an FLP trigger immediate capital gains taxes?
Answer: It depends entirely on the partnership's asset composition and how distributions are structured. Generally, pro-rata distributions of property may not trigger immediate tax. However, disproportionate distributions or distributing cash that exceeds a partner's outside basis under Internal Revenue Code Section 731 can provoke sudden tax liabilities.
Question: Does unwinding an FLP require the consent of all family partners?
Answer: The required approval depends on the original partnership agreement and applicable state law. A dissolution may require a majority or unanimous vote. If younger generations hold limited voting rights, the general partners might possess authority to initiate liquidation, though broad family consensus can prevent operational delays and disputes.
Question: Can we just wait until the 2026 tax exemption change before acting?
Answer: Waiting until the scheduled post-2025 change to the Tax Cuts and Jobs Act exemption can be risky. Dissolving a partnership involves complex legal property transfers, localized deed recordings, and tax basis audits that frequently take six to twelve months. Delaying administrative action can result in the founder passing away before the intended restructuring is complete.
Question: What is the difference between inside and outside basis in an FLP?
Answer: Inside basis refers to the partnership's tax basis in the underlying assets, while outside basis reflects an individual partner's tax basis in their ownership interest. Over decades, these numbers often diverge, making a detailed basis review—and potentially a Section 754 election—important before dissolution.
Question: How should we store our estate planning documents after dissolution?
Answer: Once complex entities are eliminated, new wills, trust iterations, deeds, and account inventories should be secured carefully. Families increasingly use encrypted digital vault solutions to give authorized fiduciaries and descendants centralized access to updated ownership records and post-dissolution directives when needed.
