Energy Transfer LP common unitholders receive an annual Schedule K-1 (Form 1065), not a Form 1099-DIV for their ET partnership-unit income. Energy Transfer is a publicly traded master limited partnership, so partnership tax items are allocated to unitholders rather than reported as ordinary corporate dividends.
Why ET common unitholders get a K-1
Energy Transfer identifies itself as a publicly traded master limited partnership. It says the partnership generally is not subject to federal or state income tax; instead, annual income, gains, losses, deductions, and credits flow through to unitholders, who report their allocated shares on individual tax returns. See Energy Transfer’s tax information.

That is why “1099 or K-1?” is not a choice between interchangeable forms for ET common-unit income. The IRS explains that partnership amounts may be reported on Schedule K-1, while a dividend payer reports dividend categories on Form 1099-DIV. The applicable form depends on the issuer’s tax treatment and the kind of item being reported, not simply on the fact that an investment paid cash. See IRS Topic 404.

It does not say every unitholder needs a K-3. Check your package and reporting circumstances, and consult the applicable instructions or a qualified tax professional if you are unsure.
When the 2025 K-1 was available
Energy Transfer reported that 2025 common-unit K-1 packages became available online on March 13, 2026. The company expected mailed packages to arrive between March 16 and March 25, 2026. These dates apply to the 2025 tax-year package only; they do not establish when a later year’s package will be released. See Energy Transfer’s 2025 tax-information availability notice.

For corrections to account details, the company says to contact your broker as well.

The company lists support at 1-800-617-7736, Monday through Friday, 8:00 a.m.–5:00 p.m. Central Time, and 800-854-9346 outside the U.S. Contact details and hours can change, so check the current tax information page before calling.

What this answer does—and does not—cover
This answer concerns Energy Transfer LP common unitholders and ET partnership units. It should not be applied automatically to a different Energy Transfer security, a former holding, or another entity with a similar name. Your tax reporting can also depend on whether you sold or transferred units, your account, state of residence, and personal tax circumstances. The K-1 and its statements provide information for your situation; they do not determine every filing obligation in a general-purpose answer.
