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.

Why MLP Estate Planning Is Different

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 taxed at ordinary rates on sale), and §1014 step-up at death (which eliminates both 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.

The 6-Article Series

  1. When Step-Up Basis Beats a Trust — The core argument: §1014 eliminates roughly $18,268 in deferred tax on a single EPD position, $48,535 across a canonical 5-MLP portfolio. Who should read: Everyone, start here.
  2. MLPs in a Living Trust — Tax-invisible while alive, three Day-1 options at death: distribute ($34,681 net) vs. hold-in-trust ($20,393 net) vs. sell at step-up ($195,695 lump). Who should read: If you have a revocable living trust.
  3. Community Property and MLPs — Married in WA, TX, CA, or six other CP states? Both halves step up at first death under §1014(b)(6). Extra federal tax eliminated: roughly $19,703 on an EPD position. Who should read: If married in a community property state.
  4. The MLP Inheritance Playbook — A 90-day day-by-day guide: broker phone script, basis correction, hold-vs-sell decision, fridge-printable checklist. Who should read: If you just inherited MLPs.
  5. MLPs in an Irrevocable Trust — UBTI, trust-rate compression, IDGT crossover calculator, §675(4) swap-power rescue, 16-year trust autopsy ($20,908 all-in cost). Who should read: If MLPs are inside an irrevocable trust.
  6. Why Your Estate Attorney Doesn’t Understand Your MLPs — The professional knowledge gap, with email templates, intake questionnaire, and annual review checklist. Who should read: CPAs, advisors, estate attorneys.

What Connects All Six Articles

Every article 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.
