What Happens When You Sell an MLP?

When you decide to sell a Master Limited Partnership (MLP), the tax implications can be more complex than a typical stock sale. Unlike regular corporate stocks, MLPs come with unique tax characteristics—especially when it comes to realizing gains.

The gain from selling an MLP isn't treated as a single type of income. Instead, it's typically split into two components: ordinary income and capital gain (or loss). This dual nature arises because of the depreciation and depletion deductions that reduce your tax basis over time—deductions that must be "recaptured" when you sell.

Here’s where it gets important: the portion of the gain that’s classified as ordinary income—often due to depreciation recapture—is subject to Unrelated Business Income Tax (UBIT). This matters particularly for tax-exempt investors, like IRAs, because UBIT can trigger a tax liability where there normally wouldn’t be one.

For example, if you’ve held an MLP in a retirement account and sell it at a profit, the recapture portion of that gain could be taxable to the IRA under UBIT rules, even though most retirement account gains aren’t taxed. The capital gain portion, on the other hand, may not be subject to UBIT, depending on the circumstances and applicable exceptions.

Timing and cost basis tracking are crucial. Every distribution you receive during ownership can reduce your tax basis, which in turn increases your taxable gain when you sell. Failing to track this accurately can lead to surprises at tax time.

In short, selling an MLP isn’t as straightforward as selling a stock. The mix of ordinary income and capital gain, combined with UBIT exposure, means investors—especially those holding MLPs in tax-exempt accounts—need to plan carefully. Consulting a tax advisor familiar with energy partnerships can help avoid unintended tax bills and ensure compliance.
