When Australian business owners talk to me about entering the US, the conversation usually starts where it should – growth.
A bigger market, deeper capital, more customers, stronger partnerships.
The opportunity is real. What is often underestimated, though, is how quickly momentum can slow due to tax and reporting issues that were never properly mapped at the start. In the US, you are rarely dealing with one simple compliance system. Federal rules are only part of the picture. State tax, registration and sales tax obligations can arrive much earlier than many businesses expect.
One of the first things I usually encourage clients to think through carefully is the entity itself.
Too often, the structure is treated as something that can be tidied up later. In practice, that can be an expensive mistake. A C corporation files Form 1120 and is taxed separately. A partnership files Form 1065 and pushes tax items out to the owners through Schedule K-1. A single-member LLC is generally disregarded for US income tax purposes unless it elects to be taxed as a corporation. On paper that may sound technical, but commercially it matters a great deal, because the wrong structure can create complexity long before the business has properly found its feet.
If an Australian group is looking at a US LLC, I would be especially careful. Where a foreign-owned US disregarded entity has reportable related-party transactions, Form 5472 can come into play, and it is filed with a pro forma Form 1120. The penalty for missing that filing starts at $25,000. That is exactly the kind of issue that catches decent businesses off guard—not because they are doing anything aggressive, but because nobody warned them early enough that the reporting obligation existed in the first place.
The state-tax piece is where many founders realise that the US is less one market and more fifty overlapping systems. Sales tax, state income tax, franchise tax and registration obligations can arise in different ways and at different times. Even the “business-friendly state” conversation needs a bit of nuance. Texas has franchise tax, Florida has corporate income/franchise tax, and many states now apply economic nexus rules that can pull remote sellers into registration and collection once thresholds are met.
Financial reporting deserves a little more attention than it usually gets at the start as well. In a public company context, SEC reporting can mean ongoing Form 10-K and Form 10-Q filings. More broadly, US financial reporting still revolves around GAAP. In practice, the challenge is often not understanding the theory, but ensuring the US numbers can be reported cleanly and consistently within the wider group without constant rework.
Hiring in the US is another area where practical business decisions and compliance meet very quickly. Employers generally need to withhold federal income tax and Social Security and Medicare taxes from wages, and most employers also need to deal with unemployment taxes at both federal and state levels. On top of that, worker classification matters. The IRS looks at the full relationship and the degree of control, not just what the contract happens to call someone. That is why I always say that calling a person a contractor is not the same thing as them actually being one.
Once the US business starts moving money across borders, the international rules need to be treated seriously. US persons with foreign financial accounts may have an FBAR filing obligation once aggregate balances exceed $10,000, and intercompany charges between an Australian parent and a US operation need to satisfy the arm’s-length standard. The best time to think about that is before the structure goes live, not halfway through an audit trail reconstruction exercise.
The good news is that none of this is unmanageable.
But it does reward businesses that treat tax and financial reporting as part of commercial strategy, rather than as admin to be cleaned up later.
The businesses that usually do well in the US are not always the ones that move fastest. They are often the ones that enter with the clearest structure, the best discipline and the fewest surprises. In my experience, that is where good advice still pays for itself.
