§751 Recapture: The Hidden MLP Tax Trap Explained

When you sell MLP units, a portion of your gain is reclassified as ordinary income under IRC §751 — taxed at up to 37%, not the 20% capital gains rate. This is called §751 recapture, and it applies even if you sell at an overall loss. Your broker does not calculate this. Most tax software does not handle it automatically. If you own MLPs and plan to sell eventually, this page explains what will happen.

What §751 Is and Why It Exists

Congress enacted IRC §751 to prevent partners from converting ordinary income into capital gain by selling their partnership interest instead of waiting for the partnership to sell its underlying assets. Without §751, a partner could receive years of depreciation deductions (reducing basis and sheltering income) and then sell the partnership interest at a capital gains rate — effectively converting ordinary depreciation recapture into a lower-taxed capital gain.

The mechanism: §751 identifies “hot assets” within the partnership. For MLPs, the hot assets are primarily unrealized receivables, which includes depreciation recapture under §1245 (equipment, compressors, processing facilities), §1250 (buildings, certain structures), and §1254 (oil and gas wells, intangible drilling costs). It also includes inventory items, though these are typically less significant for midstream MLPs.

§751 hits hardest on asset-heavy MLPs with large depreciable infrastructure. Energy Transfer owns $100B+ in total assets across three entities. Enterprise Products (EPD) has $70B+ in depreciable pipeline and processing assets. The more physical infrastructure the MLP owns, the more accumulated depreciation flows through your K-1, and the larger your §751 exposure grows each year you hold.

How It Works: The Mechanics for MLP Sales

Step 1: Calculate your total gain or loss. This is sale proceeds minus your K-1-adjusted basis — NOT the cost basis your broker shows. Your broker never sees your K-1. See why your broker’s basis is wrong.

Step 2: The MLP provides a Sales Schedule with your K-1 in the year of sale. This schedule shows the §751 ordinary income amount and the capital gain/loss amount. You do not calculate §751 yourself — the MLP calculates it based on the partnership’s accumulated depreciation and your pro-rata share.

Step 3: Report the §751 ordinary income. There is active debate among practitioners about the correct form — some use Form 4797 (Sales of Business Property), others report on Schedule E. The IRS has not issued definitive guidance specific to PTP §751 reporting. The most defensible approach: report on Form 4797, Part II, and attach a copy of the Sales Schedule as a disclosure statement.

Step 4: Report the capital gain/loss on Schedule D via Form 8949. Use adjustment Code B (if short-term, basis reported to IRS) or Code E (if long-term, basis reported to IRS) to correct the broker’s wrong basis.

Key K-1 boxes: Box 20 Code AB reports §751 gain. Code AC reports collectibles (§1250) gain. Code AD reports unrecaptured §1250 gain. The partnership also files Form 8308 (Report of a Sale or Exchange of Certain Partnership Interests) to notify the IRS that a §751(a) exchange occurred.

IRS disclosure requirement: Per Reg. §1.751-1(a)(3), a partner selling an interest in a partnership with §751 property must include a statement with their return showing the separately computed gain or loss attributable to §751 property. In practice: attach the MLP’s Sales Schedule as a PDF to your return. Most tax software does NOT auto-generate this statement — you may need to add it manually as an attachment.

Worked Example: Selling EPD at a Gain

All numbers are illustrative. Your actual §751 amount comes from the Sales Schedule your MLP provides with your final K-1.

Purchase: 500 units at $26.00 = $13,000 initial basis

10 years of K-1 adjustments: Distributions reduced basis, ordinary losses (from depreciation) reduced basis, liability share changes shifted basis

Ending K-1-adjusted basis: ~$8,200

Broker basis still shows: $13,000

Sale: 500 units at $30.00 = $15,000

Total gain per IRS: $15,000 − $8,200 = $6,800

§751 ordinary income (from Sales Schedule): ~$3,400

Capital gain portion: $6,800 − $3,400 = ~$3,400

Tax on §751 ordinary at 37%: $3,400 × 0.37 = $1,258

Tax on capital gain at 20%: $3,400 × 0.20 = $680

Total tax: $1,938

vs. $1,360 if ALL capital gain (what broker’s basis would suggest: $15,000 − $13,000 = $2,000 × 20%)

Worked Example: Selling at a LOSS — and Still Owing Ordinary Income Tax

This is the scenario that devastates unprepared investors. Most people — and many tax preparers — assume §751 recapture only applies when there is an overall gain. This is wrong. Per The Tax Adviser (AICPA), ordinary gain under §751 is fully recognized whether there is an overall gain OR loss on the sale.

Same position: 500 units, K-1-adjusted basis $8,200

Original purchase: $26/unit ($13,000) — an economic investment of $13,000

Sale: 500 units at $15.00 = $7,500 — an economic loss of $5,500

Total loss per IRS: $7,500 − $8,200 = −$700

§751 ordinary income (STILL recognized): ~$3,400

Capital loss: −$700 − $3,400 = −$4,100

You owe ordinary income tax on $3,400 at up to 37%

You can deduct only $3,000 of the capital loss per year (§1211(b))

Net year-1 tax impact: Pay tax on $400 of net income ($3,400 − $3,000) despite losing $5,500 economically

The remaining $1,100 capital loss ($4,100 − $3,000) carries forward to future years at $3,000/year. You lost money, you owe tax this year, and it takes multiple years to fully use the capital loss. This is why §751 planning matters BEFORE you sell.

Why Your Broker Gets This Wrong

Your broker receives your purchase price from the trade confirmation. They do NOT receive K-1 data — they never adjust your basis for distributions, income allocations, depreciation, or liability changes. The 1099-B they send the IRS shows the wrong cost basis. In the gain example above, the broker reports $2,000 of capital gain ($15,000 − $13,000). The IRS expects $6,800 of total gain ($3,400 ordinary + $3,400 capital). That $4,800 discrepancy will trigger an IRS notice. You are responsible for correcting it using the K-1 Sales Schedule and Form 8949 with adjustment Code B or E. See Why Your Broker’s MLP Basis Is Wrong for the full explanation.

The Silver Linings: Suspended Losses and §199A

Suspended passive losses are your best offset. Under §469(g), when you completely dispose of your entire interest in a PTP, all previously suspended passive losses from that PTP are released. These released losses offset §751 ordinary income first. This is the single most valuable tax planning insight for MLP sellers.

Example: Your K-1 has accumulated $1,600 of suspended passive losses over your holding period (losses you couldn’t use because PTP losses can only offset PTP income from the same entity under §469(k)). At sale, those $1,600 are released: $3,400 §751 ordinary income − $1,600 released suspended losses = $1,800 net ordinary income. The effective §751 tax drops from $1,258 to $666.

Important: Suspended losses are only released on a complete disposition of all units in that specific PTP. Selling half your position does NOT trigger the release. If you plan to sell, sell ALL units in the same tax year to unlock the suspended loss offset.

§199A QBI deduction. The 20% QBI deduction for qualified PTP income (made permanent by OBBBA, July 2025) may also apply to reduce the effective tax rate on §751 income. However, this is complex: it depends on your total taxable income, whether §751 income qualifies as QBI for a PTP, and interactions with the §199A wage/property limitations. Consult a tax advisor for your specific situation.

The Estate Planning Escape: Why Some Investors Never Sell

Under IRC §1014, heirs receive a stepped-up basis to fair market value at the date of death. This single provision eliminates:

  • All accumulated basis erosion from years of distributions
  • All §751 recapture exposure — the depreciation recapture disappears entirely
  • All embedded tax liability from the difference between broker basis and IRS basis

The trade-off: suspended passive losses are lost at death (they do not transfer to heirs under §469(g)(2)). But for most long-term MLP holders, the basis reset far more than compensates. An investor with $13,000 original cost, $8,200 adjusted basis, and $3,400 of §751 exposure passes MLP units worth $15,000 to heirs — heirs receive a $15,000 basis, zero recapture, and can sell immediately with zero tax.

This is why the “hold forever and pass to heirs” strategy exists for MLP investors. The §751 avoidance alone can save tens of thousands of dollars on large positions.

What Your Tax Return Should Show

When you sell MLP units, your return needs these components:

  • Form 8949: Capital gain/loss with adjustment code correcting broker basis
  • Schedule D: Summary of capital gains/losses from Form 8949
  • Form 4797: §751 ordinary income (Part II)
  • Disclosure statement: Per Reg. §1.751-1(a)(3), attach the MLP’s Sales Schedule showing the separate computation of §751 and capital gain
  • Schedule E: Final K-1 activity for the year of sale

Most tax software does NOT auto-generate the disclosure statement or properly split §751 from capital gain. You may need to override the software’s default treatment and manually add the Sales Schedule as a PDF attachment to your e-filed return.
