Sole trader, almost always. A sole trader is you, operating under an ABN, with the business income flowing onto your personal return at working holiday maker rates. A company is a separate legal entity with its own tax at 25%, its own filings and its own costs.
What is the actual difference?
Legal separation. A sole trader is not separate from the business: the income is your income, it goes on your individual return, and you are personally liable for what the business owes. Registration is the ABN and nothing more.
A company has its own ABN, its own tax obligations, and limited liability that protects personal assets. It also requires registration with ASIC, annual review fees, separate financial accounts, a company tax return, a director identification number and ongoing director obligations. That overhead exists whether the company trades or not.
How do the tax rates actually compare?
Badly for the company, at these income levels. A sole trader who is a working holiday maker pays 15% on the first $45,000 of business income and 30% above it. A company pays a flat 25% on every dollar from the first.
On $30,000 of ABN income the sole trader position is $4,500 of tax and the company position is $7,500, before any of the company's running costs. Then the money still has to come out of the company as salary or dividends, which is taxed again in your hands.
What would a company actually cost?
Enough to make the comparison one sided. ASIC registration is in the region of $600, the annual review fee is a few hundred more, a company tax return has to be prepared separately from your personal one, and the director obligations include identity verification.
The exit is the standing problem. A visa limited director who leaves Australia with a dormant company still has ASIC obligations, and they accrue in your absence. A sole trader closes the whole thing by cancelling the ABN, which is free and takes minutes.
When would a company genuinely make sense?
In situations that essentially never describe working holiday work. Multiple owners sharing a business, liability heavy contracting where insurance is not sufficient protection, or income high enough that the tax and structuring advantages outweigh the running costs, which is a threshold far above what a 417 or 462 year produces.
Licensed specialist trades such as electrical and plumbing are the closest real case, and those require qualifications most working holiday makers do not hold. Delivery riding, farm contracting, cleaning and freelance work do not come near it.
What if a platform or employer insists on one?
Treat the requirement as something to investigate, not an instruction. There are legitimate contexts where a principal will only engage incorporated contractors, usually for insurance reasons on large sites.
The demand can also exist to push obligations away from whoever should be carrying them. If someone wants you incorporated for what is plainly hourly supervised work, the classification question comes first, and our guide to the employee versus contractor test covers how that is decided.
What about personal liability as a sole trader?
Real but usually small, and cheaper to insure than to structure around. For cleaning, hospitality, delivery and basic trades the exposure is limited, and public liability insurance covers most of it at a modest cost.
Compare an insurance premium against the total cost of forming and maintaining a company for a stay of a year or two. For almost every working holiday maker, the premium wins.
Are partnerships or trusts ever relevant?
Rarely, and for the same reasons. A partnership is two or more people sharing business income, with its own return and its own rules about how income is split and who is liable. A trust holds income or assets for beneficiaries and exists mainly for asset protection and distribution flexibility.
Both add administration to a situation that does not have the scale to justify it. If two backpackers are genuinely running something together, that is worth advice rather than a default answer.
Does the structure change what you can deduct?
Barely, which removes the last argument people make for incorporating. A sole trader deducts the same genuine business expenses a company would: tools, vehicle costs on a logbook or per kilometre basis, the work share of phone and internet, insurance, licences and fees for managing your tax affairs.
What the company adds is not deductions but administration, which is itself a cost. Our guide to ABN deductions sets out what is claimable either way.
Would anything move you off sole trader?
The facts that would move it are specific and uncommon. If none of the points below describes your situation, sole trader is the answer.
- How much you expect to earn under the ABN, since the working holiday maker rate beats company tax throughout the realistic range.
- Whether anyone else shares ownership of the work.
- Whether the work carries liability that insurance cannot reasonably cover.
- Whether a principal genuinely requires incorporation, and why.
- How long you will be in Australia, since company obligations continue after you leave.
- Whether the arrangement is really contracting at all, which is the first question rather than the last.
Whatever the structure, the income is reconciled in the working holiday tax return, and you can estimate your tax refund once you know what the year came to.
