A new U.S. tax proposal, dubbed the One Big Beautiful Bill, is making waves – and not in a good way for Australian investors. While the name might sound promising, this bill could have serious financial consequences, particularly for superannuation funds and small businesses with exposure to the U.S. market.

Why It Matters for Australian Investors
Australian super funds currently have around $400 billion invested in the U.S., benefiting from long-standing tax concessions under international treaties. However, the proposed bill, backed by the Trump administration and passed through the U.S. House of Representatives, would impose higher taxes on countries perceived to be discriminating against U.S. businesses – Australia among them.
If this bill becomes law, Australian super funds could lose key tax advantages. That means potentially lower returns for millions of Australians who rely on their super to fund retirement.
The Broader Implications
Even if you’re not directly investing in U.S. markets, the knock-on effects could still impact you. Super fund performance plays a big role in retirement planning, and lower investment returns may create added financial pressure. For small businesses and global operators, increased tax complexity and uncertainty could drive up costs and disrupt planning.
Tax experts are warning that this legislation could override existing treaties between the two countries. And it’s not limited to big corporates – any individual or business with U.S. exposure could be affected.
What’s Being Done About It
Industry groups, including the Financial Services Council, are urging the Australian Government to intervene through diplomatic and trade negotiations. At the same time, major superannuation funds have begun lobbying U.S. lawmakers directly, reminding them that Australia is a vital source of capital for American markets. While there is some political opposition in the U.S., experts caution that bills once thought unlikely have passed in the past. It’s far from a done deal, but the risks are real.

What You Should Do Now
We’re not at panic stations yet – but as former PM John Howard might put it, we’re in the “alert but not alarmed” phase. With global tax laws shifting, it’s smart to stay informed and take a proactive approach.
Here’s what we recommend:
- Stay updated on changes to international tax rules
- Make sure your retirement and investment plans are flexible
- Talk to a financial adviser, especially if you have U.S. exposure – a U.S. tax specialist may also be helpful
