What Is The Definition Of A Small Business In Australia?

“Small business” sounds straightforward, but in Australia the definition changes depending on who’s asking and why. Tax concessions, employment law, consumer protections and even reporting obligations all use different tests.

If you’re planning, growing or restructuring your business, it’s important to know which definition applies to you. That way, you can access the right concessions, meet your legal obligations, and avoid surprises.

In this guide, we’ll break down the main definitions of “small business” in Australia and explain what they mean in practice. We’ll also cover key legal implications and the documents that help small businesses operate with confidence.

Why The Definition Of “Small Business” Matters

The size of your business can impact tax concessions, HR rules, reporting and contract protections. Getting it wrong can lead to missed benefits or non-compliance.

Here are common areas where the definition really matters:

• Tax: Access to small business tax concessions depends on your “aggregated turnover.”
• Employment: Whether you’re a small business employer affects unfair dismissal rules, redundancy pay and notice periods.
• Contracts: The Australian Consumer Law (ACL) gives additional protections to small businesses when dealing with standard form contracts.
• Financial Reporting: Company size can change your reporting obligations under the Corporations Act.
• Statistics and Grants: Government and research bodies may use statistical definitions for programs and grants.

Because each regime uses its own test, you might be a “small business” for one purpose but not another. The key is to identify which definition applies in each context and assess yourself against that specific test.

What Is A Small Business Under Australian Law?

Here’s a plain-English breakdown of the main definitions you’ll come across in Australia, with what each one is used for.

1) Australian Tax Office - Small Business Entity (SBE)

For many tax concessions, the Australian Taxation Office (ATO) uses the Small Business Entity concept. You’re an SBE if your aggregated turnover is less than $10 million.

• Aggregated turnover means the annual turnover of your business plus that of any “connected” or “affiliate” entities, Australia-wide.
• The SBE test is used for things like simplified depreciation and certain tax concessions.

If you’re weighing up the SBE rules, it helps to understand how the ATO looks at turnover, affiliates and connected entities. We’ve covered this in more detail under Small Business Entity (SBE).

2) Fair Work - Small Business Employer (Fewer Than 15 Employees)

Under Australia’s national workplace laws, a “small business employer” is one with fewer than 15 employees.

• Headcount is by persons, not full-time equivalent (FTE).
• Casuals are counted if they’re employed on a regular and systematic basis.
• Independent contractors are not employees for this purpose.

Why it matters: small business employers have a longer minimum employment period before an employee can access unfair dismissal (12 months instead of 6), and are exempt from paying redundancy pay under the National Employment Standards if they have fewer than 15 employees.

3) Australian Consumer Law - Small Business For Unfair Contract Terms

The ACL’s unfair contract terms regime protects small businesses that enter standard form contracts. Since November 2023, a business is generally considered “small” here if it has:

• Fewer than 100 employees, or
• Less than $10 million in annual turnover.

This definition is different from the Fair Work headcount or the ATO SBE turnover threshold. It matters when you’re signing supplier agreements, SaaS terms or other “take it or leave it” contracts. Alongside unfair terms, you must still avoid misleading conduct under section 18 of the ACL.

4) Corporations Act - Small Proprietary Company

If you operate through a company, “small proprietary company” is a separate concept that affects financial reporting and audit requirements. A proprietary company is small if it satisfies at least two of these:

• Consolidated revenue of less than $50 million
• Consolidated gross assets of less than $25 million
• Fewer than 100 employees

These thresholds do not change your status as a small business for tax or employment law, but they do influence whether you need to prepare and lodge certain financial reports.

5) ABS Statistical Definitions

The Australian Bureau of Statistics (ABS) often uses headcount-based categories for research, such as:

• Micro: 0-4 employees
• Small: 5-19 employees
• Medium: 20-199 employees
• Large: 200+ employees

These are statistical, not legal, and they don’t directly determine compliance obligations. They can still be useful for benchmarking and grant eligibility.

How Do I Work Out My Headcount And Turnover?

Because definitions vary, your method should match the test you’re applying. Here are practical tips for the two most common ones.

Counting Employees (Fair Work)

• Count each person on your payroll as one employee.
• Include casuals who work on a regular and systematic basis.
• Exclude independent contractors (unless a law specifically says otherwise).
• Include employees of associated entities (if relevant to the headcount test).

If you’re unsure whether a worker is a contractor or an employee, that distinction matters across many areas of law. As a starting point, consider whether their work meets the threshold of a business activity in its own right.

Calculating Aggregated Turnover (ATO SBE)

• Use your ordinary income from carrying on a business for the year.
• Add the income of any “connected” or “affiliate” entities, not just your main ABN.
• Exclude GST you’ve collected on sales.

This figure determines whether you access certain SBE concessions. If you’re close to the threshold or have entities in a group, get tax advice to confirm your aggregated turnover.

What Legal Obligations Change If You’re A Small Business?

Being a small business can lighten some obligations, but it can also trigger extra protections you should know about. Here are key differences you’ll likely come across.

Employment Law (Small Business Employer)

• Unfair dismissal minimum employment period is 12 months (for larger employers, it’s 6 months).
• Small business employers (fewer than 15 employees) are generally exempt from redundancy pay under the NES.
• Notice of termination and other entitlements still apply.

Clear and well-drafted Employment Contracts help you set expectations from day one and reduce the risk of disputes.

Unfair Contract Terms (ACL)

• If you have fewer than 100 employees or turnover under $10 million, you may be protected when signing standard form contracts.
• Terms that create significant imbalance, aren’t reasonably necessary and cause detriment can be unlawful.
• Penalties now apply to businesses that propose or rely on unfair terms.

Review your own standard terms too. If you supply to other small businesses, make sure your templates are compliant so you can enforce them with confidence.

Tax Concessions (SBE)

• SBEs can access simplified depreciation and some other concessions.
• Separate rules apply for small business CGT concessions (different tests and thresholds).

Because tax rules change frequently, speak with your accountant for the latest concessions and thresholds. From a legal perspective, make sure your structure supports your tax strategy and growth plans.

Reporting And Governance (Companies)

• “Small proprietary companies” generally have lighter reporting obligations than large proprietary companies.
• As you scale, you may need to adopt more formal governance (for example, a Company Constitution and board processes).

If you plan to raise capital or bring on co-founders, it’s wise to put a Shareholders Agreement in place early to agree decision-making, equity and exit terms.

Am I A Small Business If I’m A Sole Trader Or A Company?

Your business structure doesn’t by itself determine whether you’re a small business. The applicable test (headcount, turnover or thresholds) is what matters.

• Sole traders and partnerships can be small businesses if they pass the relevant turnover or headcount tests.
• Companies can be small businesses for tax or ACL purposes, and separate tests apply for “small proprietary company” status.

If you’re just getting started, compare your options and think about risk, funding and growth. Many owners start simple and incorporate later for liability protection and investor readiness. If company structure is on your roadmap, our team can help with a smooth Company Set Up.

Practical Steps If You’re On The Threshold

It’s common to sit on the line between “small” and “not small,” especially when you’re growing. Here’s how to stay on top of it without losing focus.

• Track headcount monthly, including regular casuals, so you know when you cross the 15-employee threshold.
• Monitor revenue (and affiliate group revenue) for the ATO SBE test and tax planning.
• Review standard form contracts you sign and issue to ensure ACL compliance.
• Refresh HR documents and processes as you scale, including probation, performance management and termination procedures.
• Keep your corporate governance fit-for-purpose as you grow, from cap tables to board approvals and your Company Constitution.

If any of this feels complex, that’s normal. It’s best to get tailored legal guidance early so you’re set up for success and not scrambling later.

What Legal Documents Should Small Businesses Have?

The right contracts protect your revenue, customer relationships and brand. While every business is different, most small businesses should consider the following:

• Customer Terms or Service Agreement: Sets clear payment terms, scope, warranties and liability limits when you sell goods or services.
• Website Terms & Conditions: Rules for using your site or platform, including acceptable use and IP ownership.
• Privacy Policy: Explains how you collect, use and store personal information. If you collect any customer or user data, a Privacy Policy is essential.
• Employment Agreements: For employees, use tailored Employment Contracts (full-time or part-time) and set expectations around duties, confidentiality and termination.
• Contractor Agreements: Clarify scope, deliverables, IP ownership and payment terms when engaging contractors.
• Non-Disclosure Agreement (NDA): Protects confidential information when you’re discussing opportunities with suppliers, partners or contractors.
• Shareholders Agreement: If you have co-founders or investors, a Shareholders Agreement sets the rules for decision-making, issuing shares and exits.
• Company Constitution (If Incorporated): Governs internal company processes, director powers and share issues; complements your shareholders agreement.

You might not need all of these on day one, but getting your core documents in place will save time and reduce risk. If you sell to consumers or other businesses, make sure your terms also comply with the ACL to avoid issues with misleading conduct under section 18.

Common Questions About Small Business Status

What happens if I grow out of “small business” status?

Nothing dramatic changes overnight, but some obligations do switch. For example, once you reach 15 or more employees, the small business exemptions under the Fair Work Act no longer apply. Likewise, you may lose access to certain SBE tax concessions as your aggregated turnover increases. Plan ahead so the transition is smooth.

Can I restructure to access small business concessions?

Potentially, but you should look at the bigger picture first-operational risk, investor needs, and long-term tax outcomes. A restructure shouldn’t be purely about meeting a threshold. If you are considering a change, speak with your accountant and get legal support to document the steps properly.

Do contractors count as employees?

Not for the Fair Work small business headcount test. However, be careful about misclassification-if a “contractor” is really working as an employee, that can trigger employment law liabilities. Having the right agreements and processes helps you manage this risk.

Key Takeaways

• There isn’t one definition of “small business” in Australia-the test depends on the law you’re applying (tax, employment, ACL or corporate reporting).
• For tax concessions, the ATO uses the Small Business Entity threshold of less than $10 million in aggregated turnover.
• Under Fair Work, a small business employer has fewer than 15 employees, which affects unfair dismissal rules and redundancy pay.
• The ACL protects small businesses (fewer than 100 employees or under $10 million turnover) from unfair terms in standard form contracts.
• Company size for reporting is a separate concept-“small proprietary company” uses revenue, assets and employee thresholds.
• Track your headcount and turnover, keep contracts and policies up to date, and review your position as you grow to stay compliant.
