An MLP (Master Limited Partnership) is a publicly traded partnership investing in US energy infrastructure — mainly pipelines, storage, and midstream processing. MLPs must distribute 90%+ of earnings, making typical yields 6–10%. Tax structure: distributions are often Return of Capital (tax-deferred), but the K-1 form adds filing complexity.

A Master Limited Partnership (MLP) is a publicly traded US business structure used primarily in energy infrastructure — natural gas pipelines, crude oil transport, storage terminals, and processing facilities. MLPs pay 6-10% distribution yields and avoid corporate income tax entirely, making them one of the highest-yielding legal structures in US equities.
MLPs are partnerships, not corporations. They issue units (not shares) and pay distributions (not dividends). The partnership structure means all earnings flow directly to unitholders — the MLP itself pays no federal income tax. This tax pass-through is why yields are so high: roughly 70-90% of typical MLP distributions are classified as return of capital, not ordinary income.
| Feature | MLP (e.g. MPLX, ET) | C-Corp (e.g. Enbridge, TC Energy) |
|---|---|---|
| Tax structure | Pass-through, no corporate tax | Corporate tax applies |
| Payout form | Distribution (partially return of capital) | Dividend (ordinary or qualified) |
| Tax form | K-1 (complex) | 1099-DIV (simple) |
| Typical yield 2026 | 7-10% | 5-8% |
| Non-US investors | 37% withholding (unfavorable) | 15-25% withholding (standard treaty) |
| RRSP/IRA eligible | UBTI risk in IRAs | Standard eligible |
For European investors in particular, the choice between US MLPs and Canadian pipeline companies deserves careful analysis. The tax treatment and income predictability differ substantially:
| Factor | US MLPs (EPD, ET, MPLX) | Canadian Pipelines (Enbridge, TC Energy) |
|---|---|---|
| Withholding tax (non-US) | 37% (or treaty rate, varies) | 15% (Canada-EU/DE treaty) |
| Tax complexity | K-1 form required, UBTI risk, complex | Standard dividend, no K-1 |
| Dividend yield | 6-9% distribution yield | 5-7% dividend yield |
| Dividend growth | Low to moderate (2-4%/year) | 3-6%/year (Enbridge targets 3%+ through 2026) |
| Coverage ratio | 1.6-2.0x DCF | 1.5-1.8x DCF |
| UBTI risk (for tax-deferred accounts) | Yes — MLP holdings in IRAs/401k trigger unrelated business taxable income | No — standard foreign dividends, no UBTI |
For European dividend investors, the conclusion is clear: Canadian pipeline companies deliver comparable infrastructure exposure (fee-based contracts, regulated volumes, 5-7% yield) without the US tax complexity. Enbridge's 7%+ dividend yield with 3%+ annual growth, plus the 15% withholding treaty rate, makes it the preferred choice over a US MLP for most non-US investors.
For US investors with taxable accounts and tolerance for K-1 complexity, Enterprise Products Partners (EPD) at 7-8% yield with 20+ years of consecutive distribution growth represents the premium quality tier of the MLP universe. Its debt/EBITDA under 3x and coverage ratio above 1.7x make it one of the most financially conservative MLPs available. The K-1 administrative burden is the main trade-off.

For US-based investors, MLPs offer pass-through taxation (income taxed at personal level, not at corporate level). For non-US investors (including European investors), this structure often creates complexity without benefit. The practical comparison:
Choose C-Corps when: You're a non-US investor, you want simplicity, you want dividends classified as "qualified" under US tax law. Examples: Kinder Morgan (KMI), Williams Companies (WMB), Energy Transfer (ET as C-Corp equivalent). These pay dividends reportable as "qualified dividends" — often with favorable US withholding rates under tax treaties.
Consider MLPs when: You're a US-based investor in a tax-advantaged account (IRA/401k), the specific pipeline has no C-Corp equivalent, or the yield premium is significant enough to justify the tax complexity. Note: MLPs in US tax-advantaged accounts can trigger UBTI (Unrelated Business Taxable Income) — consult a tax advisor.
For European retail investors: the practical answer for 90%+ of cases is C-Corp pipeline operators. The dividend is simpler, the tax treaty treatment is cleaner, and the yields are often comparable. Midstream Investing Guide →

When investors search for "natural gas MLPs," they're looking for a specific sub-sector: midstream companies that transport, process, and store natural gas and NGLs (Natural Gas Liquids). These are often considered the most stable MLPs because natural gas demand is structural — homes, power plants, and LNG export terminals all depend on it.
Take-or-pay contracts: The defining feature of quality natural gas MLPs. Customers pay even if they don't use the capacity. This creates utility-like cash flows regardless of commodity prices — critical for dividend stability.
EBITDA visibility: Top-tier natural gas MLPs like Kinder Morgan (KMI) or Williams Companies (WMB) typically guide 80-90% of annual EBITDA under long-term contracts. This predictability supports consistent DCF/share growth and distribution increases.
Fee-based vs. commodity-exposed: Always check what percentage of revenue is fee-based vs. directly exposed to natural gas spot prices. Fee-based >80% = lower risk. Commodity-exposed = higher yield but more volatile distributions.
This is crucial: traditional MLPs (K-1 partnerships) create significant tax complexity for non-US investors:
For European investors: C-Corp conversions (KMI, Targa Resources, MPLX) are typically more accessible. Or consider Canadian pipeline C-Corps (Enbridge, TC Energy) for similar infrastructure exposure without K-1 complexity.
One of the most overlooked issues for non-US investors in MLPs is the tax treatment — which is materially different from regular dividends:
Practical recommendation: For European investors seeking midstream exposure without MLP tax complexity, consider Kinder Morgan (KMI), TC Energy (TRP), or Enbridge (ENB) — all C-Corps with pipelines and growing dividends.
