The $21,000 Pty Ltd Illusion: Why Just Having a Company Won’t Stop the ATO From Taxing You Like a Sole Trader
⚡ Executive Summary & Key Takeaways
- The Pty Ltd Illusion: Incorporating a proprietary limited company does not automatically protect your earnings from high personal tax rates under ATO Personal Services Income (PSI) rules (ITAA 1997 Part 2-42).
- The 80/20 Threshold: If 80% or more of your PSI comes from a single end-client, you cannot self-assess as a Personal Services Business (PSB) unless you meet specific ATO criteria (Results Test, Unrelated Clients Test, Employment Test, Business Premises Test).
- Consequences of PSI Application: Fulfilling PSI criteria forces 100% income attribution to the individual at top marginal rates (up to 47%), stripping corporate 25% tax retention benefits.
- Tripartite Accuracy: You must track income against underlying End Clients—not recruitment middlemen—to accurately calculate the 80% rule. Read our Tripartite Billing Guide.
Thousands of Australian software engineers, enterprise architects, and technical project managers spend $1,000 to $3,000 incorporating a proprietary limited company (Pty Ltd), believing it creates an absolute tax shield. They expect to pay a flat 25% corporate tax rate, retain profits in their company vault, and avoid top individual marginal tax rates.
Unfortunately, without active Personal Services Business (PSB) compliance, the ATO's Personal Services Income (PSI) rules can slice right through your corporate wrapper.
What is Personal Services Income (PSI)?
Under Part 2-42 of the Income Tax Assessment Act 1997 (ITAA 1997), PSI is income that is mainly (more than 50%) a reward for your personal effort, skills, or expertise. If you earn income as an IT consultant, mechanical engineer, or data scientist, your invoice revenue is almost always classified as PSI.
When PSI rules apply, your company is legally prohibited from retaining profits at the 25% corporate tax rate. All net income must be attributed to you personally as salary or wages and taxed at your individual marginal tax rate (up to 47% including Medicare levy).
How to Qualify as a Personal Services Business (PSB)
To retain profits inside your company and unlock strategic wealth mechanisms like Franked Dividend Extraction, your company must pass the ATO's PSB self-assessment tests:
| ATO PSB Assessment Step | Rule Requirement | Compliance Indicator |
|---|---|---|
| Step 1: The 80% Rule | No single end client accounts for 80% or more of total PSI | Must pass Step 1 or meet the Results Test to self-assess |
| Step 2: The Results Test | Paid for achieving a specific result, providing tools, and liable to rectify defects | Pristine Statements of Work (SOW) & warranty clauses |
| Step 3: Unrelated Clients Test | Services provided to 2+ unrelated entities via public offers/direct business development | Active business website, quotes, and direct outreach history |
The Recruiter Trap: How Middlemen Corrupt Your 80% Rule & Unrelated Clients Test
If you contract through recruitment agencies (e.g., Hays, PeopleBank, Paxus), your financial accounting software may tag all invoice payments with the recruitment agency's name.
If you deliver work for three completely separate companies through the same recruiter, generic software will group 100% of your income under that single recruiter, giving the false appearance that you failed the 80% Rule. Rake solves this by maintaining a decoupled tripartite billing structure, tagging revenue to the actual End Client.
📌 ATO Statutory Evidence Note (Unrelated Clients Test & 80% Rule): Under ITAA 1997 s 80-20 and ATO Taxation Ruling TR 2022/3 Paragraph 48, the ATO enforces a strict look-through rule to the underlying End Client (not recruitment agency ABNs) when evaluating both the 80% Concentration Rule and the Unrelated Clients Test. Rake's PSI engine measures compliance directly against End Client IDs (`clientId`).
Unlocking the Corporate Vault
Once you verify that your practice qualifies as a PSB, you can safely retain unneeded profits inside your company vault, saving tens of thousands of dollars each financial year. Read our full numerical breakdown in Sole Trader vs Pty Ltd at $250k.
Frequently Asked Questions
Does incorporating a Pty Ltd protect me from PSI rules?
No. Under Part 2-42 of the ITAA 1997, Personal Services Income (PSI) rules look through corporate wrappers. If more than 50% of the contract value is reward for your personal labor, skills, or expertise, the income is PSI regardless of whether you bill through an ABN, Pty Ltd, or trust.
What happens if my company fails the PSB tests?
If your company fails to qualify as a Personal Services Business (PSB), all net PSI income must be attributed to you individually and taxed at individual marginal tax rates. You also lose deductions for home office expenses and payments to associates.
What is the 80% Rule in ATO PSI compliance?
The 80% Rule states that if 80% or more of your PSI comes from a single client (including their associates) during a financial year, you cannot self-assess as a PSB unless you obtain a formal Personal Services Determination (PSD) from the ATO.
How does Rake calculate PSI 80% rule compliance with recruitment agencies?
Rake decouples the agency Billing Entity from the underlying End Client. If you contract through Hays for two different resource companies, Rake attributes the revenue to the true End Clients, keeping your 80% rule metrics accurate.
