You may have seen the viral headline about a new U.S. tax bill called the One Big Beautiful Bill, but what does it mean for Australian investors, especially super funds and small businesses with US exposure? Turns out, it could mean a hit to investment returns.

Where are things at?

Australian superannuation funds currently have about $400 billion invested in the US and tax concessions are currently available under existing tax treaties. This could change.

A new bill, backed by the Trump administration and recently passed through Congress proposes higher taxes on countries seen to be discriminating against US businesses, including Australia.

The bill was signed into law by President Trump on July 4, 2025. As a result, Australian super funds could face higher taxes on US investments, directly affecting the long-term returns of super funds.

The implications

Even if you don’t have direct investments in the US, this matters. If your business is tied to superannuation funds or if you rely on consistent super returns for your retirement planning, changes like these can add pressure. It also adds a layer of uncertainty for Aussie businesses operating globally.

As trade tensions rise and tax rules shift, doing business internationally becomes more complex and potentially more costly. Tax experts say these changes could override existing treaties between the US and Australia. And they’re not just aimed at big corporates, any individual or entity with US exposure could potentially be affected in some way.

What's being done?

Industry groups including the Financial Services Council are calling on the Australian Government to step in and protect Australian investors through diplomatic and trade channels. Major super funds have already met with US lawmakers, reminding them that Australia is a significant source of capital for US markets and that strong partnerships go both ways.
