Yes, Energy Transfer (ET) issues a K-1 โ but your K-1 package actually contains THREE separate partnerships: ET, USAC, and SUN. Each has its own EIN and its own basis calculation. If you only enter one K-1 in your tax software, your return is wrong. ET's 2025 K-1 is expected online March 16, 2026.

ET’s three-entity structure means three separate basis calculations. Your broker tracks none of them correctly. → Calculate your real ET/USAC/SUN basis free
Energy Transfer has confirmed that 2025 K-1 tax packages will be available online starting March 16, 2026. Mailed packages follow between March 18–31, 2026. Access your K-1 at taxpackagesupport.com/et or call 800-617-7736.
When you buy ET, you own interests in three separate PTPs: Energy Transfer LP (parent, ~85–90% of basis allocation), USA Compression Partners (USAC), and Sunoco LP (SUN). Each has a separate K-1, a separate EIN, and a separate basis calculation. Under §469(k), losses from one entity cannot offset income from another — they are separate passive activity “canisters” for tax purposes.
We now have dedicated guides for each of ET’s sub-entities:
→ Sunoco LP (SUN) K-1 Guide — the fuel distribution arm
→ USA Compression Partners (USAC) K-1 Guide — the compression services arm
Each has its own basis erosion profile and state filing implications.
Create three separate K-1 entries in your tax software — one per entity, each with its own EIN from Part I, Box A. Check “Publicly Traded Partnership” for each. Enter Box 1 (ordinary income/loss), Box 19A (distributions), Item K (liabilities), and Box 20 codes Z and AE (§199A QBI) per entity.
Example: 200 units at $14.50 = $2,900 total. After initial allocation (ET ~$2,552, USAC ~$203, SUN ~$145) and three years of distributions (~$1.27–$1.29/unit/year), combined ending basis drops to approximately $1,920 — 66% of purchase price. Your broker still shows $2,900. That $980 gap means underreported gain if you sell.
Energy Transfer owns massive physical infrastructure across all three entities. The depreciation creates §751 exposure. Upon sale, cumulative depreciation is recaptured as ordinary income taxed up to 37%. Long-term ET holders should expect meaningful §751 amounts. For a full walkthrough of how §751 works, see our §751 Recapture deep dive.
ET operates in approximately 44 states. Focus on your home state plus any state with allocated income above $1,000. Louisiana, Pennsylvania, and Oklahoma have low thresholds. Texas has no income tax but a franchise tax that’s irrelevant for individual unitholders. ET offers composite returns in some states. The year you sell is critical — disposition gains push more states above filing thresholds. See our complete MLP State Filing Requirements guide.
If you acquired ET units through the ETE/ETP merger (Oct 2018), Enable Midstream (ENBL) merger (Dec 2021), or Crestwood (CEQP) merger (Nov 2023), your initial basis differs from a market purchase. Check Form 8937 on ET’s investor relations page for the exchange ratio and tax treatment.
