Why MLP Estate Planning Is Different
Disclaimer

MLP estate planning is not regular estate planning. Three mechanics make it different: basis erosion (your adjusted basis drifts toward zero as distributions exceed allocated income), §751 ordinary-income recapture (accumulated depreciation that gets taxed at ordinary rates on sale), and §1014 step-up at death (which eliminates both of the above in a single stroke). Miss any of these, and a standard trust structure can destroy tens of thousands of dollars in embedded tax value.
The professional knowledge required spans two disciplines taught separately: Subchapter K (partnership taxation) and Subchapter A/B (estates and trusts). Most estate attorneys can draft a flawless trust without ever learning what a K-1 basis worksheet looks like. Most CPAs can reconcile K-1s for twenty years without touching a Form 1041. The gap between them is where direct MLP holders lose the most money.
This 6-part series covers every trust type, every family situation, and every professional coordination challenge — with computed examples from the MLP Portfolio Tax Simulator. Every dollar value traces back to the IRS Partner’s Basis Worksheet engine, and every tax claim cites a specific IRC section, Treasury Regulation, or IRS publication.
Key Takeaways
- §1014 step-up at death eliminates all accumulated basis erosion and §751 ordinary recapture on direct-held MLP positions — roughly $18,268 in federal tax on a 1,000-unit EPD position held 20 years, roughly $48,535 across a canonical 5-MLP portfolio.
- Revocable trusts preserve step-up; irrevocable trusts may not — assets inside a revocable trust sit in the gross estate and qualify for §1014, while IDGTs and most bypass/dynasty trusts are excluded by design.
- Community property states get double the step-up at the first spouse’s death under §1014(b)(6) — both halves reset, not just the decedent’s half. The advantage on a canonical EPD position: roughly $19,703 in additional federal tax eliminated.
- Heirs who correct broker basis before selling avoid overpaying thousands in unnecessary tax — brokers frequently carry forward the decedent’s eroded basis instead of the date-of-death FMV that §1014 provides.
- The CPA-attorney coordination gap is where MLP investors lose the most money — structural, not individual. The series provides the shared quantitative language (basis, §751 exposure, §1014 value) that bridges it.

What Connects All Six Articles
Every article in the series answers a different question, but they all orbit the same core tension: §1014 step-up is the most valuable estate planning feature MLPs have, and almost every structural decision you make — trust type, spouse ownership, timing of death — determines whether you keep it or lose it.
Article 1 establishes the baseline (direct ownership + step-up). Article 2 shows how a revocable trust preserves it. Article 3 shows how community property doubles it. Article 4 shows heirs how to capture it operationally. Article 5 shows the damage when an irrevocable structure destroys it. Article 6 shows why professional coordination fails when partnership taxation and estate law talk past each other.
Read any one article and you’ll get a working answer for your situation. Read all six and you’ll have a complete mental model of MLP estate planning — one that your CPA and estate attorney can share, because every claim cites a specific IRC section.

Frequently Asked Questions
MLP estate planning centers on IRC §1014 step-up basis at death, which eliminates accumulated basis erosion and §751 ordinary-income recapture. The optimal strategy for most direct MLP holders is direct ownership (or a revocable living trust) to preserve step-up, combined with community property classification where available. Irrevocable trusts introduce trust-rate compression, potential UBTI under §512, and may forfeit step-up entirely. Start with article 1 in this series — "When Step-Up Basis Beats a Trust" — for the core argument and computed dollar values.
A revocable living trust is generally the best fit: it preserves §1014 step-up (because trust assets remain in the gross estate), avoids probate, and has zero tax impact during the grantor's lifetime. Irrevocable trusts (IDGTs, bypass trusts, dynasty trusts) introduce trust-rate compression (top bracket hit at roughly $15,000 vs. $580,000 for individuals), potential UBTI, and typically forfeit §1014 step-up. See article 2 ("MLPs in a Living Trust") and article 5 ("MLPs in an Irrevocable Trust") for the side-by-side computed comparison.
Yes. This 6-part series covers step-up strategy, revocable trusts, community property, inheritance mechanics, irrevocable trusts, and professional coordination. Every example is computed from the IRS Partner's Basis Worksheet engine with specific dollar amounts tied to real MLP portfolios. The series spans roughly 20,000 words of IRC-cited analysis, with interactive calculators, printable checklists, and email templates for CPA-attorney coordination.
The MLP Portfolio Tax Simulator at lucasandersen.ai includes an estate planning mode that computes §1014 step-up value, per-beneficiary inheritance analysis, post-death sell-vs-hold comparison, and CPA PDF export for attorney/CPA meetings. Interactive calculators are embedded throughout this article series — including an IDGT crossover calculator, post-death scenario comparison, and community property double step-up computation. The K-1 Basis Tracker provides the per-position adjusted basis that every estate planning calculation depends on.
Yes. Article 6 ("Why Your Estate Attorney Doesn't Understand Your MLPs") is written specifically for CPAs and advisors. It includes an Annual MLP Client Review checklist, a pre-meeting intake questionnaire, copy-paste email templates for CPA-attorney coordination, and a Red Flags diagnostic to identify at-risk clients. The underlying argument: MLP estate planning requires knowledge from both Subchapter K (partnerships) and Subchapter A/B (estates/trusts), and most professionals have only one.
