Personal services income in Australia is income produced mainly from an individual's own skills or effort, and the Australian Taxation Office (ATO) applies specific rules so it's taxed to the person who earned it. A core threshold is the 50% rule: if more than 50% of the income from a contract is for your labour, skills, or expertise, the entire amount from that contract is treated as PSI.
You sign a contract through your company, the invoice is paid to the company bank account, and it feels like you're running a normal business. Then tax time arrives and one question starts driving everything else: is this really business income, or is it income the ATO will trace back to you personally?

Who this article is for: contractors, medical professionals, consultants, IT specialists, and new migrants setting up an Australian entity who need a practical view of how the PSI rules may affect structure, deductions, and record-keeping.
Understanding Personal Services Income
A practical way to think about PSI is this. If a client is mainly paying for you, rather than for a product, a system, inventory, or an income-producing asset, you're in PSI territory.
For many professionals, that's the starting point for answering what is personal services income Australia in real life. An IT contractor, specialist consultant, architect, or medical practitioner may bill through a sole trader ABN, company, trust, or partnership, but the structure doesn't decide the tax outcome on its own.
The 50% rule is the first gate
The Australian Taxation Office explains that if more than 50% of the income from a contract or invoice is for an individual's labour, skills, or expertise, the entire amount from that contract is PSI. If 50% or less is for personal effort, none of that contract income is PSI. The ATO also makes clear that this is applied contract by contract or invoice by invoice, not just by looking at your overall setup through a company or trust. You can read the ATO guidance on personal services income and the narrower page on income that is PSI.
That detail matters. Plenty of contractors assume incorporation changes the character of the income. Often it doesn't.
Practical rule: PSI is about the source of the income, not the label on the entity that receives it.
Why the rules exist
The policy intent is straightforward. The PSI regime was introduced to stop income being diverted through companies, partnerships, or trusts to access tax advantages such as income splitting, broader deductions, or lower tax rates. That's why the rules often affect professions where earnings are closely tied to one person's own expertise.
A simple analogy helps. Selling software licences, physical goods, or the use of equipment looks more like business income generated by assets or systems. Selling your own time, diagnosis, design judgement, coding ability, or strategic advice looks more like PSI.
- Medical work: A doctor paid mainly for clinical skill may be earning PSI, even if the receipts flow through an entity.
- IT contracting: A developer engaged for their personal technical capability often needs to test each contract carefully.
- Migrant professionals: New arrivals often set up a company early, but the company itself doesn't switch off the PSI rules.
For a more general explainer, this personal services income guide offers a useful plain-English companion read. If you're dealing with attribution through an entity, Everglow's note on attributed personal services income is also relevant.
Takeaway: if the client is mainly paying for your personal labour or expertise, start with the assumption that PSI may apply and test each contract on its own facts.
Are You Operating a Personal Services Business?
Being caught by PSI doesn't automatically mean the restrictive outcome will apply. The key question then becomes whether you qualify as a personal services business (PSB).
The 80% rule changes the pathway
A major decision point is client concentration. If 80% or more of your PSI comes from one client and that client's associates in a financial year, you generally can't self-assess as a PSB under the standard tests and may need an ATO determination instead. The ATO sets this out in its guidance on working out if the PSI rules apply.
That's why one large contract can create a tax issue even when the work feels commercial. Commercially, it may be a business. For PSI purposes, concentrated income can block self-assessment.
The PSB tests in practice
If the gateway allows it, the statutory tests are the results test, unrelated clients test, employment test, and business premises test. Each one is trying to answer the same underlying question. Are you carrying on a business, or are you effectively selling one individual's labour through an entity?
The employment test includes a clear labour-share benchmark. At least 20% of the principal work must be performed by others, or the business must employ one or more apprentices for at least six months of the year. That threshold often matters for growing consultancies, engineering boutiques, and medical service entities.
Passing a PSB test isn't about optimistic wording in a service agreement. It depends on what the business actually does and what records can prove.
A few practical observations help:
- Results test: Stronger where you're paid for an outcome and carry genuine responsibility for delivery.
- Unrelated clients test: Stronger where clients are independent of each other and you actively win work from the market.
- Employment test: Stronger where principal work is genuinely performed by others, not just admin support.
- Business premises test: Stronger where you maintain premises that are genuinely separate and used as business premises.
For readers weighing whether structure and substance align, the broader choice of entity still matters for other tax, legal, and cash flow reasons. This comparison of company vs sole trader in Australia may help frame that decision alongside PSI.
| Decision point | What it asks | Why it matters |
|---|---|---|
| PSI character | Is the income mainly from personal labour, skill, or expertise? | If yes, PSB testing becomes relevant. |
| Client concentration | Is most PSI coming from one client group? | Heavy concentration may prevent self-assessment. |
| Business substance | Do the statutory tests show a genuine business structure? | If yes, the PSI attribution regime may not apply. |
Takeaway: the PSB question is less about what you call your business and more about who pays you, how the work is won, who performs it, and what evidence supports that story.
Tax Obligations and Deductions Under the PSI Rules
If your income is PSI and you don't qualify as a PSB, the practical effect is usually felt through deductions first and structure second.
The ATO states that an individual whose income is classified as PSI generally cannot claim deductions for rent, mortgage interest, rates, or land tax for their home office. By contrast, a PSB may be able to claim occupancy expenses if it meets the business premises test. That distinction is set out on the ATO page covering deductions and GST for personal services income.
What this means in day-to-day terms
Many contractors are surprised by this. They've paid for software, equipment, accounting support, and a home office arrangement, and they assume the usual small business deduction pattern will apply. Under PSI, some of that logic narrows quickly.
If PSI applies, think less like a broad trading business and more like a tightly ring-fenced professional activity tied to the individual who performed the work.
A useful way to frame it is by contrast:
- Home occupancy costs: These are generally restricted where the income is PSI and you're not a PSB.
- Entity-based tax planning: The rules may attribute the income back to the individual who earned it.
- Normal business flexibility: This may be reduced compared with a business that qualifies as a PSB.
What usually works and what doesn't
Practically, the safer approach is to separate direct work-related costs from structural or occupancy-style claims and review them carefully before lodging. If your setup relies heavily on home-based delivery, this is often the first area to stress-test.
If you're reviewing claims already made or planning upcoming deductions, this guide on how to claim business expenses can help frame the broader deduction principles. It doesn't replace PSI analysis, but it helps identify where standard business thinking may need adjustment.
Takeaway: when PSI applies, deduction limits can change the economics of your structure, especially for home-based professionals who assumed ordinary small business treatment.
Worked Example: An IT Contractor in Sydney
Wei is a new migrant IT professional living in Parramatta. He sets up a company because that feels organised, credible, and familiar to larger clients. He then lands a single contract worth $150,000 for a year-long project with one enterprise client in Sydney.
PSI thus becomes a decision framework, not just a compliance label.
How Wei should think about it
First, Wei asks whether the contract income is mainly a reward for his own technical skill and effort. On these facts, that's likely the starting concern. The next issue is concentration. Because the year's PSI is coming from one client, the 80% gatekeeper becomes central to whether he can self-assess as a PSB.
If Wei can't rely on the usual PSB pathway, the company may still receive the money, but the tax analysis doesn't stop at the company bank account. The structure is not the answer by itself.
| Item | Scenario 1: PSI Rules Apply | Scenario 2: Operates as a PSB |
|---|---|---|
| Income source | Single Sydney client contract for Wei’s own IT expertise | Same contract, but business qualifies outside the attribution regime |
| Initial tax question | Is the contract mainly paying for Wei’s labour and skill? | Same starting question |
| Client concentration effect | Concentration creates a PSB self-assessment problem | Would need a valid path to PSB treatment |
| Deductions | More limited, especially around home occupancy-type costs | Broader business treatment may be available depending on facts |
| Strategic outcome | Entity structure offers less tax separation than expected | Business structure has more room to operate as a genuine enterprise |
The practical lesson from Parramatta
Wei's mistake wouldn't be setting up a company. The mistake would be assuming the company answers the PSI problem. For many IT contractors, the essential planning work sits earlier: client mix, contract terms, delivery model, and evidence.
If Wei expects to stay with one client for the full year, he should get advice before claiming broad business deductions or relying on the company as if PSI doesn't exist. If his work pattern changes later, the analysis may change too.
For readers comparing reporting positions across structures, this explainer on how sole traders pay tax is a useful companion.
Takeaway: Wei's example shows why PSI is a structural tax concept. The invoice may be issued by a company, but the ATO still asks who really earned the income.
Proactive Structuring and Compliance Strategies
The strongest PSI planning usually happens before the year closes, not after the return is drafted.
In the current work environment, government guidance is especially clear on one point: taxpayers need to prove they meet the PSB tests, not merely assert it. Business.gov.au highlights the importance of keeping records of separate clients, contracts showing payment on results, and details of subcontractors or business premises used. The guidance appears on business.gov.au's PSI overview.
What usually helps
Remote work, hybrid delivery, and platform-based engagements mean old assumptions don't always fit. A contractor can look independent on LinkedIn and still have weak PSI evidence if the contracts, invoicing pattern, and work records tell a narrower story.
A stewardship approach usually focuses on the following:
- Client diversification: If commercially realistic, avoid over-reliance on one payer.
- Contract design: Where appropriate, align agreements with genuine deliverables and business risk.
- Subcontracting evidence: Keep records showing who performed principal work and on what basis.
- Business premises support: If relying on premises, maintain clear evidence of actual use and separation.
The modern PSI question is often not “What do you call yourself?” It's “What can you prove if the ATO asks?”
Strategy is better than repair work
Specific advice can save rework. A contractor changing from one long engagement to several project-based engagements may need a different record-keeping system, different contract terms, and a different expectations setting around deductions. For broader planning, resources on small business tax planning strategies can help frame the commercial side. Where PSI is in play, Everglow Prosperity may assist with tax advisory, accounting, and structure review as one option among professional advisers.
Takeaway: proactive PSI management means aligning commercial reality, tax treatment, and evidence while the work is being done, not trying to reconstruct the story at tax time.
Frequently Asked Questions About PSI
Does PSI affect GST?
PSI and GST are different concepts. PSI is about how income is taxed and what deductions may be available. GST is a separate indirect tax regime. You may still have GST obligations depending on your circumstances, even if the income is PSI, so the analysis shouldn't be collapsed into one question.
I'm a medical professional working across several clinics. Do the PSI rules still matter?
Yes, they may. Medical professionals are one of the groups commonly affected because the income is often tied closely to personal expertise and labour. Working across multiple sites can help commercially, but the PSI position still turns on the legal and factual details of how the income is earned and evidenced.
If my circumstances change during the year, do I reassess?
Yes, that's often sensible. A contractor might begin the year with one dominant client and later expand to a broader client base, or the reverse. PSI analysis is heavily fact-based, so a major shift in contracts, work method, or staffing usually deserves a fresh review before lodgment.
Can I rely on my company or trust to avoid PSI?
No, not by itself. That's a common misunderstanding. The PSI regime exists precisely because using a company, trust, or partnership doesn't automatically change income that is really a reward for one person's labour, skill, or expertise.
What records should I keep if I think I'm a PSB?
Keep contracts, invoices, evidence of separate clients, records showing how you won work, and documents that support any reliance on subcontractors or business premises. In a remote or digital practice, organised evidence matters more than ever because the burden of proof sits with the taxpayer.
Can I ask the ATO for certainty?
Depending on your circumstances, you may need an ATO determination if client concentration blocks self-assessment. That can be particularly relevant where one major engagement dominates the year but the broader business model still has features of a genuine enterprise.
