You’ve set up a company. Your invoices go out under a business name. You’ve got a logo, a website, maybe even accounting software and a separate bank account. But one client still makes up most of your work, and most of what they pay for is your time, judgement, and expertise.

- What Is Personal Services Income Really
- Applying the Four Critical PSI Self-Assessment Tests
- PSI Rules Applied Your Deduction and Tax Outcomes
- Managing Your PAYG GST and BAS Obligations with PSI
That’s where many contractors, consultants, and small operators start to feel uneasy. You look like a business commercially, but for tax purposes the ATO may still treat that income as personal services income.
This catches more people than it should. IT consultants, engineers, project managers, designers, medical professionals, and specialist advisers often assume that using a company or trust changes the tax outcome. Sometimes it doesn’t. If the income is mainly a reward for your own efforts, the structure on top may not do what you think it does.
The practical issue isn’t just classification. It’s what follows. Can the income stay in the entity? Can you split it? Which deductions survive? What happens if you also hold rental properties, lodge BAS, or live overseas while billing Australian clients? Those are the decisions that create either a clean file or a painful amendment later.
Are You a Contractor Unsure About Your Tax
A common version of this problem looks like this. An engineer leaves employment, sets up a Pty Ltd, signs a contract with a former industry contact, and starts billing monthly. The work is real. The business is real. But the income still comes from that person’s own brain, experience, and output.
The same uncertainty turns up with software developers, marketing specialists, and medical contractors. They ask a fair question. “Am I running a business, or am I just earning income that the ATO will push back onto me personally?”
That question is exactly why the PSI rules exist. They are integrity rules. Their job is to stop someone from taking income that is earned from personal effort and parking it in a company, trust, or partnership just to get a better tax outcome.
This doesn’t mean every contractor has a problem. It means labels don’t decide the issue. Calling yourself a consultant, creating a company, or issuing invoices with GST doesn’t settle whether the income is PSI.
A quick sense-check helps. If a client is mainly paying for you rather than for substantial plant, goods, software, systems, or a team-delivered service, PSI should be on your radar.
PSI is less about what your ABN says and more about what the client is buying.
If you’re still not sure whether your working arrangement looks like contracting or employment, this guide on employee or independent contractor ATO rules is a useful companion. The two issues are separate, but they often overlap in the same fact pattern.
The hard part isn’t learning the acronym. The hard part is knowing what to do when your facts sit in the grey zone. That’s where careful contract review, invoice wording, and recordkeeping matter.
What Is Personal Services Income Really
A contractor sets up a company, invoices through the company bank account, registers for GST, and assumes the income belongs to the company. Then tax time arrives and the harder question surfaces. What was the client paying for?
Personal services income is income that mainly comes from an individual’s own labour, skill, expertise, or effort. The practical threshold is simple. If more than half of what the client pays under a contract is really for your work rather than for goods, equipment, intellectual property, systems, or a broader business operation, the contract income is usually PSI under ATO guidance.
A practical way to judge the 50% rule
A cake business provides a simple illustration.
If the sale price mostly reflects ingredients, production capacity, delivery, packaging, and a repeatable business process, the baker’s personal effort is only part of the value. If the customer is paying for one baker’s design skill and hands-on craftsmanship for a custom wedding cake, the personal effort component is doing most of the work in the price.
The ATO applies the same logic to contractors and consultants. It asks what the client bought in substance, not what the invoice says.
A few common fact patterns make this easier to test:
- Trainer or consultant: A client pays for your knowledge, presentation, and delivery, with only minor handouts or materials included. That will often be PSI.
- IT contractor with significant software resale or licensing: If a large part of the contract price relates to software provided to the client, and your labour is the smaller component, the income may fall outside PSI.
- Medical or professional specialist working through a company: If patients, clinics, or counterparties are really paying for your personal judgement and qualifications, PSI risk is usually high even if the billing entity is a company.
- Investor or overseas Australian with an Australian service entity: If the entity also holds investments or foreign income, that does not change the character of service fees earned from your own work. PSI can still apply to that service income and catch people who assume a mixed-income structure gives them protection.
That last point matters. I often see people focus on the entity and miss the income stream. PSI is tested contract by contract, based on what generated the payment.
Why this distinction matters
The PSI rules exist to stop income earned from personal effort being diverted through a company, trust, or partnership just to get a better tax result. That is why many contractors get caught even though their structure is otherwise valid.
The trade-off is straightforward. A company or trust can still be useful for asset protection, admitting business partners, or building a broader enterprise. But if the income is mainly a reward for your own work, the tax law may still pull that amount back to you personally for PSI purposes.
Practical rule: If the client would have paid the same price to your business regardless of which suitably qualified team member delivered the work, the income looks more like ordinary business income. If the client engaged the business because they wanted you, your reputation, or your judgement, PSI risk rises.
At this point, mistakes become expensive. Contractors often assume PSI is only a definition issue. In practice, it drives later outcomes on deductions, PAYG treatment, and how much confidence you can have in your structure if the ATO reviews it. For overseas Australians, it can also create false comfort. Foreign residency, a foreign company, or offshore cash flow does not automatically change the PSI character of Australian-sourced service income.
If you have worked with UK contractor rules, the closest policy comparison is IR35. The rules are different, but the underlying concern is similar. Income that looks like it came from one person’s work should not gain a tax advantage just because it sits inside an entity. This overview of What Is IR35 and Why Does It Matter to UK Contractors gives useful context.
Applying the Four Critical PSI Self-Assessment Tests
A contractor can look fully independent on paper and still fail PSI. I see this often with professionals who trade through a company, invoice professionally, carry insurance, and assume that settles it. It does not. The critical question is whether your facts support treatment as a personal services business.
If more than half of what the client pays you is really for your labour, skill, or expertise, Division 86 is in play. The self-assessment tests are the filter. Pass the right test and the restrictive PSI rules may not apply. Fail them and a structure that looked tax-effective can start working against you.
For investors and Australians working across borders, this is a common trap. A foreign company, overseas bank account, or side income from investments does not change the character of Australian-sourced income that mainly comes from your own services.
Start with the results test
This is usually the strongest route because it focuses on how the work is priced and delivered, not just how your business is labelled.
You generally need most of your PSI to satisfy all three elements:
- You are paid to produce a result.
- You provide your own tools or equipment.
- You are responsible for fixing defects at your own cost.
On paper, plenty of contracts seem close. In practice, the weak point is usually the first or third limb. If you bill by the hour, work under daily supervision, and turn up to supply effort, the arrangement starts to resemble labour hire. If you deliver a defined outcome for an agreed fee and carry rework risk, your position is stronger.
Pass style example
A software developer agrees to build and deploy a payment integration for a fixed price. The contract specifies deliverables, milestone acceptance, and defect remediation at the developer’s cost. The developer uses their own hardware and development tools. That fact pattern is far more consistent with a contracted result.
Fail style example
A project manager works five days a week for one client, bills a daily rate, uses the client’s systems, attends internal stand-ups, and has no genuine liability if the project slips or the work needs correction. That usually points back to labour being supplied, not a result being sold.
A practical test helps here. Ask: if the work takes you twice as long as expected, who wears that cost? If the answer is "the client, because I keep billing", the results test is already under pressure.
Then check the 80% rule and the unrelated clients test
Client concentration causes a lot of PSI problems because contractors often count invoices instead of relationships.
If 80% or more of your PSI comes from one client, or from one client and its associates, the unrelated clients path is usually closed. At that point, you generally need the results test or another specific test to get out of the PSI rules.
The mistake is simple. Three purchase orders, monthly invoices, and two departments inside the same corporate group still usually mean one client source for PSI purposes.
Pass style example
A cybersecurity consultant wins work from several unrelated businesses through tenders, a public website, and direct marketing. No single client dominates the year. That pattern is much easier to defend.
Fail style example
An engineer spends almost the whole year with one mining client, then picks up a short weekend job for a family friend’s company. The side job rarely changes the outcome if one client still accounts for the clear bulk of the PSI.
Use this short review before year-end, not after:
- Measure client concentration annually. Monthly variation can hide a one-client year.
- Group related entities together. Sister companies and associated entities do not create diversity.
- Check how work was obtained. Open market advertising and tendering help more than private introductions through one labour network.
The employment test
This test asks whether the business has real production capacity beyond the individual whose efforts generate the income.
Support staff alone usually do not get you there. A spouse handling admin, a bookkeeper reconciling accounts, or a virtual assistant answering emails may help the business run better, but that does not usually show that principal work is being produced by others.
A stronger case is a firm where employees or genuine subcontractors perform a meaningful part of the fee-earning work. The distinction matters. If clients are buying a service capability from a small team, PSI risk can reduce. If they are still buying your judgement, your hands-on work, and your personal delivery, the structure is only a wrapper.
This is one of the areas where contractors can learn from broader worker-classification disputes. The legal tests are different, but the commercial warning signs overlap. This UK article on when a “self-employed” contractor is considered a de facto employee is a useful comparison point.
The business premises test
Many solo operators assume a home office will help here. Usually, it will not.
You generally need separate business premises that are used mainly to conduct the work, are physically distinct from your home, and are not your client’s office or a nominal desk in a shared space. The premises need to show that the business operates from its own place of business.
This is why the test is hard to satisfy in modern service industries. Plenty of legitimate businesses work remotely, but PSI law has its own criteria. A home office may still be deductible under ordinary tax rules. It often does not satisfy this PSI test.
What usually helps, and what usually hurts
| Situation | Tends to help | Tends to hurt |
|---|---|---|
| Contract terms | Fixed-fee outcomes, milestone delivery, defect liability | Hourly billing, ongoing labour supply |
| Client mix | Multiple unrelated clients from market-facing activity | One dominant client |
| Tools and systems | Your own equipment and workflow | Client equipment and close operational control |
| Delivery model | Team-based delivery or genuine subcontracted production | Work depends almost entirely on you |
| Location | Separate business premises | Home office or client office only |
Do not self-assess by business name, ABN, or company structure. Self-assess by evidence.
The documents that matter are the signed contract, scope of work, invoices, timesheets, marketing records, equipment ownership, subcontractor agreements, and year-end client totals. If those records point in different directions, fix the position early. It is much cheaper to restructure before the ATO asks questions than to defend a weak PSI position after the fact.
PSI Rules Applied Your Deduction and Tax Outcomes
Once the tests are applied, your tax position usually goes down one of two paths. The difference is practical, not academic.
Path one as a personal services business
If you pass the relevant tests, you’re generally treated as a personal services business. That doesn’t mean PSI disappears as a concept, but it usually means the harsh restriction rules don’t apply in the same way.
Commercially, this is the cleaner path. Your deductions are treated more like those of an ordinary business, assuming they otherwise satisfy normal tax rules. The structure you use also has more room to operate as intended.
Many contractors want to be here. Not because it creates magic tax savings, but because it aligns tax treatment more closely with how the business runs.
Path two where the PSI rules bite
If you fail the tests, the restrictions matter quickly.
The income is attributed back to the individual who performed the work. That’s the central consequence. A company or trust can’t retain that income at entity rates or split it across family members if the PSI rules apply.
The ATO’s PSI guidance states that if most of your PSI comes from one client, the full PSI rules apply, and that many disputes hinge on this issue. The same guidance says passing the results test for most of your PSI is critical, and failing can block many typical business deductions. It also gives practical examples where a contractor could face significantly higher tax if they fail the tests, compared with if they pass: ATO PSI guidance.
This shows the trade-off. The argument over PSI isn’t just technical. It changes after-tax cash.
The mistake isn’t only paying more tax. It’s planning as though the entity can keep or split income, then finding out later that it never could.
Deduction comparison
The table below is a practical guide only. Specific facts still matter.
| Expense Type | Deductible as a PSB? | Deductible under PSI Rules? | Notes |
|---|---|---|---|
| General business overheads | Usually yes | Often restricted | Entity-level overheads become vulnerable when PSI attribution applies |
| Rent for separate business premises | Usually yes | Can be limited unless directly allowed | Facts matter, especially where premises are mixed-use |
| Home office costs | Often available under ordinary rules | Only to the extent allowed under PSI restrictions | Keep records and separate private use carefully |
| Payments to associates for principal work | May be possible if incurred | Commonly restricted | Income splitting is a core PSI target |
| Bookkeeping and admin support | Often deductible | More likely to survive than principal labour splitting | Still must be incurred |
| Travel tied to earning the income | Depends on ordinary rules | Can be restricted in PSI settings | Review purpose and who incurred the cost |
| Entity losses | Available subject to normal rules | Restricted | PSI can prevent entity losses being used as expected |
What this means in day-to-day decisions
A few patterns come up repeatedly.
- Using a company isn’t a shield: A company can still receive PSI, but the tax outcome may flow back to the individual.
- Family payment plans often fail: Paying a spouse or relative for work they didn’t perform is exactly the sort of arrangement these rules target.
- Bundling matters: Where a contract includes substantial goods, software, or equipment, the PSI position may be different. But the economics must be real, not cosmetic.
If you’re deciding whether to expand, subcontract, lease premises, or keep operating solo, these outcomes should inform the decision early. Restructuring after an ATO query is always harder than setting up correctly from the start.
Managing Your PAYG GST and BAS Obligations with PSI
Once PSI is in the picture, your admin process has to match the tax outcome. Good intentions don’t help if the BAS, year-end accounts, and individual return all tell different stories.
The compliance pressure is getting tighter. The ATO’s 2025-26 PSI compliance program flagged an increased audit focus for contractors, especially where services are blended with property-related advice. The same material notes focus on disguised PSI, trust income splitting, AI-assisted services, and penalties that can be substantial: ATO PSI compliance discussion.
PAYG and attribution need to line up
If the PSI rules apply and income is attributed to the individual, your tax planning needs to reflect that. Don’t let the company books suggest one outcome while the individual return reports another.
That usually means checking:
- Whose return carries the income
- Whether PAYG instalments are realistic for the person ultimately taxed
- Whether any salary, drawings, or distributions match the PSI treatment
A common error is to focus only on invoicing and forget attribution. The ATO won’t.
GST is separate from PSI
People often get confused here. PSI and GST are not the same question.
You can still have a GST obligation even if the income is PSI. If your services are taxable supplies and you’re required to be registered, GST collection and reporting still need to happen in the ordinary way. PSI doesn’t cancel BAS responsibilities.
That’s why BAS coding needs to be reviewed alongside the income tax position, not after it.
A BAS checklist that avoids messy corrections
If your business earns personal services income, keep the process tight:
- Review contract wording: Make sure the BAS treatment and year-end tax treatment don’t contradict the deal.
- Track entity and individual records separately: This matters if income has to be attributed.
- Check mixed activities carefully: Property investors who also consult often blur expenses across rental and service activity. Blurred deductions become dangerous here.
- Document AI-assisted work properly: If software tools contribute to delivery, keep records showing what the client paid for and who provided the substantive service.
- Reconcile before lodgement: BAS figures, payroll records, and annual accounts should tell one coherent story.
Clean BAS lodgements don’t prove your PSI position is right, but inconsistent BAS lodgements often help the ATO find where it’s wrong.
If BAS compliance is already becoming tangled, this guide on mastering your Business Activity Statement lodgement is a practical next read.
Common PSI Pitfalls and Strategic Restructuring
The biggest PSI mistakes usually start with a reasonable assumption. “I’ve got an ABN, so I’m a business.” “I’ve incorporated, so the company pays the tax.” “I work from home, so I have business premises.” None of those statements is automatically enough.
The common traps
Some errors are repeated so often that they’re worth naming plainly.
- Treating one big client as several clients: Different projects, departments, or purchase orders don’t create unrelated clients.
- Writing hourly contracts and hoping conduct will save them: If the document says labour supply, it’s hard to argue later that you were engaged for a result.
- Paying associates without matching substance: If a spouse does real admin work, that’s one thing. If payments are just profit distribution dressed up as wages, that’s another.
- Relying on a home office as a PSI escape hatch: A legitimate home office doesn’t usually solve the business premises test.
- Mixing rental and consulting records: Property investors who also invoice for advisory or project work often contaminate their files by using the same accounts, cards, or descriptions.
Strategic decisions that can help
Restructuring can help, but only when the commercial reality changes with it.
A better structure on paper won’t beat poor facts. A company can be useful for asset protection, branding, continuity, or non-PSI income streams. But if all roads still lead back to one person selling their own labour to one main client, the PSI problem usually remains.
What tends to help is changing the business model, not just the entity.
Better moves
- Shift to project pricing where appropriate: If clients buy outcomes, the contract should say outcomes.
- Build unrelated client depth: Market-facing lead generation matters more than cosmetic diversification.
- Use real delivery capacity: Staff or subcontractors performing substantive work can change the profile of the business.
- Separate activities cleanly: If you hold rental properties and also consult, keep contracts, ledgers, and expense evidence distinct.
- Review overseas arrangements early: Australians living overseas often assume non-residency solves everything. It doesn’t if Australian obligations still exist or Australian clients still pay for services tied to you personally.
Investors and overseas Australians need extra care
Property investors often drift into consulting without redesigning their systems. They might advise on renovation strategy, sourcing, tenant issues, or project coordination while also running rental schedules. That’s where blurred deductions become dangerous. The service income and property income may need very different treatment.
Overseas Australians face another practical problem. Distance creates delays. Returns get lodged late, records are incomplete, and a company is left carrying income that may need to be reattributed. Those matters are fixable, but only if someone reviews the facts before the lodgement position hardens.
A structure review can still be worthwhile. This comparison of sole trader vs company tax benefits is useful if you’re weighing whether your current setup still matches how you earn.
Restructuring works when the legal form follows the commercial substance. It fails when the paperwork tries to disguise the same old arrangement.
Stay Compliant and Confident with Expert PSI Guidance
Personal services income isn’t hard because the definition is hidden. It’s hard because the facts are usually mixed. A contractor can be independent in commercial terms and still trigger PSI rules in tax terms.
The safest approach is practical. Review each contract. Check whether the client is paying for a result or for your time. Measure client concentration across the full year. Keep records that show who provided equipment, who bore defect risk, and how the work was obtained. If you also have rental properties, overseas income issues, overdue lodgements, or BAS obligations, make sure those records stay separate and consistent.
The earlier you review PSI, the more choices you have. You can adjust contracts before renewal, diversify clients before year-end, and fix reporting before the ATO asks questions. Leaving it until after lodgement usually turns a planning issue into a correction issue.
If your file already feels messy, that’s not unusual. It does mean you should get the position checked properly.
Personal Services Income FAQs
Does using a company stop income from being PSI
No. A company can receive the invoice payment, but the PSI rules can still attribute that income back to the individual who earned it through their own efforts.
Can I avoid PSI by adding materials or software to the invoice
Not automatically. The issue is substance. If more than half the value of the contract is still for your labour, skills, or expertise, the whole contract can still be PSI.
I work for one main client and a few small ones. Am I safe
Not necessarily. If one client accounts for the threshold discussed earlier, the unrelated clients pathway becomes a problem. Small side jobs don’t always change that outcome.
Does a home office mean I pass the business premises test
Usually no. A home office may still be valid for ordinary tax purposes, but that’s not the same as satisfying the PSI business premises test.
I live overseas now. Do PSI rules still matter
They can. If you’re still earning income connected to Australian obligations or billing Australian clients for your own services, the PSI question may still need review as part of your broader tax position.
I’m behind on lodgements. Should I wait until everything is perfect
No. Late files usually get harder, not easier. It’s better to review the PSI position, sort the records you have, and fix the lodgement strategy before the issues compound.
The ATO provides guidance through ato.gov.au, the Small Business Support Line (13 28 66), and Online Services for individuals and businesses. For complex situations, a registered tax agent provides advice tailored to your specific circumstances and professional indemnity protection. You can verify agent registration at the TPB register at tpb.gov.au.
Most tax records must be kept for five years from the date of lodgement or the date the transaction occurred, whichever is later. Records must be in English or convertible to English and must be sufficient to explain the income and deductions in your return. The ATO can request records at any time during the retention period.
Consider a registered tax agent when your affairs involve multiple income sources, business activity, investment properties, capital gains, or overseas income. Agents extend your lodgement deadline, provide safe harbour protection, and take professional responsibility for the advice given. Verify registration at tpb.gov.au.
The failure to lodge penalty is based on penalty units ($313 per unit from 1 July 2023), accruing per 28-day period for late returns and BAS lodgements. Incorrect information penalties range from 25% to 75% of the tax shortfall depending on whether the behaviour was careless, reckless, or intentional. Proactive disclosure before an audit begins typically results in significantly reduced penalties.
Tax minimisation is the legal arrangement of your affairs to reduce tax — claiming all eligible deductions, using appropriate structures, and timing income and expenses. Tax avoidance involves arrangements that technically comply with the law but achieve outcomes parliament did not intend. The ATO can apply Part IVA anti-avoidance rules to cancel benefits from avoidance arrangements.
