Master Limited Partnerships (MLPs) in Australia: 2026 Investor Guide

MLPs are investment vehicles primarily listed on US stock exchanges. They combine features of both partnerships and publicly traded companies. Most commonly, MLPs operate in the energy sector—such as oil and gas pipelines, storage, and infrastructure—but their reach is slowly expanding into areas like renewables and other infrastructure assets.

• Structure: MLPs are publicly traded partnerships. Investors, known as "unitholders," receive distributions from the partnership’s cash flow rather than traditional dividends.

• Taxation: In the US, MLPs benefit from pass-through taxation, meaning profits are distributed directly to investors, who then pay personal income tax. However, Australians investing in MLPs face a different tax scenario, which is important to understand.

• Yield: MLPs are known for offering relatively high yields compared to many traditional income investments, making them attractive to income-focused investors.

While the majority of MLPs are US-based, Australian investors can access them directly or through managed funds and exchange-traded funds (ETFs) that provide diversified exposure.

Tax treatment is a key consideration for Australians investing in MLPs. The US tax system provides certain benefits to domestic investors, but foreign investors—including Australians—encounter a different set of rules:

• Withholding Tax: Distributions from US-based MLPs to foreign investors are generally subject to a significant withholding tax. This can reduce the effective yield for Australians.

• No Franking Credits: Unlike Australian shares, MLP distributions do not come with franking credits. This means there is a risk of double taxation, as income may be taxed in both the US and Australia.

• Tax Reporting: MLPs often issue a K-1 form for tax reporting, which is not standard in Australia. This can create additional paperwork and complexity, as income must be declared to both US and Australian tax authorities.

Because of these complexities, many Australians prefer to access MLPs through ASX-listed ETFs or managed funds. These vehicles typically handle the US tax obligations internally and provide simpler Australian tax statements, making the process more straightforward for investors.

Before considering MLPs as part of your investment strategy, it’s important to weigh their potential benefits and risks.

Potential Benefits

• Attractive Yields: MLPs often provide higher income distributions than many traditional Australian income investments, which can be appealing in a low-interest-rate environment.

• Inflation Protection: Many MLPs operate essential infrastructure with revenue streams that may be linked to inflation or commodity prices, offering some protection against rising costs.

• Portfolio Diversification: MLPs typically have a low correlation with Australian equities and bonds, providing an additional layer of diversification for investors seeking to spread risk across different asset classes and geographies.

Key Risks and Considerations

• Tax Complexity: Direct investment in US-listed MLPs means navigating both US and Australian tax systems, which can be complicated and may require professional advice.

• Sector Concentration: Most MLPs are concentrated in the energy sector, particularly oil and gas. This exposes investors to sector-specific risks, including regulatory changes, commodity price fluctuations, and the global transition to renewable energy.

• Interest Rate Sensitivity: MLPs often rely on borrowing to fund infrastructure projects. Changes in global interest rates can impact borrowing costs and, in turn, affect MLP profitability and unit prices.

• Currency Risk: Since MLPs are US-dollar denominated, Australian investors are exposed to fluctuations in the AUD/USD exchange rate, which can amplify gains or losses.

• Regulatory Changes: Recent years have seen increased regulatory scrutiny, including requirements for enhanced environmental, social, and governance (ESG) disclosures. Some Australian fund managers may screen out MLPs that do not meet certain climate or sustainability benchmarks.

There are several ways for Australians to gain exposure to MLPs, each with its own advantages and drawbacks:

1. Direct Investment in US-Listed MLPs

Australians can purchase units in US-listed MLPs through an international brokerage account. This approach provides direct exposure but comes with significant tax and reporting complexity. Investors should be prepared for additional paperwork and may need to seek professional tax advice.

2. ASX-Listed ETFs and Managed Funds

A more accessible option for many Australians is to invest in ETFs or managed funds listed on the ASX that include MLPs in their portfolios. These funds handle the complexities of US tax obligations and provide investors with Australian tax statements, making the process simpler. Examples include funds that focus on global energy infrastructure or broader infrastructure themes.

3. Global Infrastructure Funds

Some Australian-based global infrastructure funds include MLPs as part of a diversified portfolio. This approach can help reduce sector and single-country risk, as these funds may invest across various types of infrastructure assets and regions.

Before investing, it’s important to review the product disclosure statement for any fund or ETF to understand its exposure to MLPs, fees, and associated risks.

If you’re considering adding MLPs to your portfolio in 2026, keep the following in mind:

• Diversification: Avoid concentrating too much of your portfolio in a single sector or asset class. MLPs can provide diversification, but should be balanced with other investments.

• Research: Understand the underlying assets, management approach, and risk profile of any MLP or fund you consider. Look for transparency in reporting and clarity around tax treatment.

• Tax Planning: Given the complexity of cross-border taxation, consider seeking advice from a qualified tax professional familiar with both Australian and US tax systems.

• Currency Management: Be aware of the impact of currency movements on your investment returns. Some funds may offer currency hedging, while others do not.

• Regulatory Developments: Stay informed about changes in US and Australian regulations that may affect MLPs, particularly around ESG requirements and tax rules.

Master Limited Partnerships can offer Australian investors access to global infrastructure income and diversification benefits. However, they come with unique tax and sector risks that require careful consideration. For those willing to navigate the complexity—or who prefer the simplicity of managed funds and ETFs—MLPs may be a useful addition to a diversified portfolio in 2026. As always, thorough research and professional advice are key before making any investment decisions.
