Can I Start A Company While Working For Another One? (2026 Updated)

It’s a common situation: you’ve got a stable job, but you also have a business idea you can’t shake. Maybe it’s a side hustle you want to take seriously, or a long-term plan to eventually leave employment and run your own company full-time.

The good news is that in many cases, you can start a company while working for another employer in Australia.

The catch? How you do it matters. If you move too quickly (or quietly), you can accidentally breach your employment contract, create a conflict of interest, or even trigger disputes about intellectual property (IP), confidential information, or client relationships.

Below, we’ll walk you through the practical and legal issues to think about in 2026, so you can build your new company while protecting your current role, your reputation, and your future business.

Can You Start A Company While Employed In Australia?

In Australia, there’s usually no blanket rule that says you can’t start a company while employed. Plenty of people incorporate a company to:

• test a business idea while keeping stable income
• separate personal assets from business risk (limited liability)
• bring in a co-founder or investor down the track
• build a “real” operating structure for a growing side project

But your ability to start (and run) a company while employed depends on factors like:

• what your employment contract says (especially exclusivity or restraint clauses)
• whether your business competes with your employer
• whether you’ll use your employer’s time, tools, systems, suppliers, or customer relationships
• whether you’re a director and have director duties to your new company
• whether your industry has special rules (finance, health, government, defence, etc.)

If you’re unsure, it’s worth treating this like a risk-management exercise: you want to grow something exciting, without jeopardising your job or creating legal problems that can follow you into your new venture.

Do You Have To Tell Your Employer?

Sometimes yes, sometimes no. It depends on your contract and workplace policies.

Many contracts require you to disclose secondary employment, side businesses, or directorships-especially if there’s any chance of a conflict. Even if it’s not explicitly required, there can be practical benefits to transparency if your side business is genuinely separate from your employer’s business.

On the other hand, if your employer is likely to see your side business as competitive (even if you don’t), it’s important to get advice on your specific situation before you disclose anything.

It can also be helpful to understand how secondary employment is usually handled in Australia, because employers often regulate it through contracts and policies rather than through a “one size fits all” legal rule.

Check Your Employment Contract First (Before You Register Anything)

Your employment contract is the first document to review-because it often contains the rules that matter most for side businesses.

If you don’t have a copy, ask HR for one (or check your onboarding email). If you have multiple documents-like an offer letter, a contract, and policies-treat them as a package.

Clauses To Look For

Here are the clauses that commonly affect whether you can start a company while employed:

• Exclusivity clauses: these may say you must devote your “working time and attention” to your employer, or that you can’t do other paid work without approval.
• Conflict of interest clauses: these usually require you to avoid situations where your personal interests interfere with your duties to your employer.
• Confidentiality clauses: these restrict use or disclosure of confidential information (during and after employment).
• Intellectual property clauses: these can assign ownership of work created “in the course of employment” (and sometimes broader than you expect).
• Restraint of trade / non-compete clauses: these may try to restrict what you can do during employment and after you leave.
• Non-solicitation / non-poaching clauses: these can restrict approaching customers, clients, suppliers, or even staff.

If your contract includes a restraint of trade clause, you’ll want to take it seriously and get advice on enforceability and risk. If you’re building a business that might overlap with your employer’s industry, a tailored Non-Compete Agreement strategy (or at least clear contract drafting and negotiation) can become a key part of your planning.

If You’re Not Sure Whether It’s “Competing”

Competition isn’t always obvious.

For example, you might think you’re starting something totally different (say, a marketing consultancy), but your employer might see you as competing if:

• you target the same type of clients
• you offer services that replace what your employer sells
• you’re using the same supplier network or industry connections
• your role gives you inside knowledge you could apply in your business

As a practical rule: if a reasonable person could say, “this side business could take revenue away from the employer,” there’s a risk you’re in competition-even if you’re not trying to be.

Avoid Conflicts: Time, Resources, Confidentiality, And IP

This is where many “side business” plans go wrong. Most disputes don’t happen because someone simply registered a company-they happen because of how they operated it alongside employment.

1) Keep It Completely Separate From Your Day Job

Even if you only work on your new business “a little bit” at work, the legal and employment risk can be disproportionate.

To stay on the safe side:

• don’t work on the business during paid work hours
• don’t use work equipment (laptop, phone, software subscriptions, email)
• don’t use work data or templates
• don’t store business documents on work drives
• don’t ask colleagues to help (even casually) using work time or systems

These steps aren’t just “good behaviour”-they help reduce the chance that your employer claims your business activities were part of your employment, or that your new business benefited from their resources.

2) Be Careful With Intellectual Property (IP) Ownership

IP disputes can be surprisingly messy. If you build a product, code, brand assets, or business systems while employed, the key question becomes: who owns it?

Depending on your role and contract terms, your employer may argue they own IP created:

• as part of your job
• using their resources
• related to their business
• during working hours

This doesn’t mean you can’t build something new. It just means you should plan carefully, document your work practices, and keep development separate from employment.

3) Don’t Use Confidential Information Or Client Lists

“Confidential information” isn’t just trade secrets. It can include pricing, quoting methods, internal processes, customer preferences, pipeline details, supplier rates, or non-public strategy.

Even if you personally helped create a list or process at work, it doesn’t automatically mean you can use it for your own company.

If your new venture involves working with clients or customers, be careful about how you source leads. A common safe approach is to build your own marketing channels from scratch (your own website, ads, content, referrals) rather than leaning on your employer’s network.

4) If You’ll Have Two Roles, Clarify The Arrangement

Some people end up effectively holding two roles-an employment role and a role in their own business. That can be manageable, but it can also trigger concerns around fatigue, performance, confidentiality, and conflicts.

If your employer is aware and supportive, it may help to document expectations clearly (for example, what hours you’re available, what industries you won’t service, and what resources you will not use).

It can also be useful to understand how dual employment issues are commonly approached, because even legitimate second roles can create compliance and performance issues if they’re not handled upfront.

How Do You Set Up The New Company The Right Way?

If you’ve checked your contract and you’re confident you can proceed, the next step is setting up your new company properly.

Many people rush this part, but a clean setup helps you:

• protect your personal assets (depending on how you structure things)
• avoid disputes with co-founders later
• look credible to customers, suppliers, and investors
• create a clear separation between “your employment” and “your business”

Choosing The Right Structure

The most common options are:

• Sole trader: simplest to start, but you’re personally liable for debts and claims.
• Company: a separate legal entity (with limited liability in many cases), often preferred for growth, partnerships, or investment.
• Partnership: can work for some co-founder arrangements, but it’s usually higher risk if not documented properly.

If you’re planning to bring in a co-founder, raise capital, or separate risk, a company is often worth considering early.

You can set up a company through a structured Company Set Up, so the basics (shareholdings, director details, registrations) are done cleanly from day one.

Don’t Skip The Rules Of The Company

When you form a company, you’ll need to decide what rules govern it. Many companies use a constitution (instead of, or in addition to, replaceable rules). This becomes especially important when there are multiple shareholders or you want custom governance.

A tailored Company Constitution can help clarify the practical “operating rules” of the company, including director decision-making and shareholder rights.

Get The Ownership Arrangements Clear Early

If it’s just you, this might be simple. But if you’re starting the company with someone else (or you think you might later), it’s worth documenting the commercial deal early.

Questions to clarify include:

• who owns what percentage of shares?
• who contributes cash, labour, or IP?
• what happens if someone leaves?
• who makes decisions day-to-day?
• how are disputes handled?

This is where a Shareholders Agreement becomes extremely helpful-because it’s designed to prevent the classic co-founder disputes that arise when expectations aren’t written down.

Conflicts Of Interest: Set Expectations In Your New Business Too

When you start your company while employed, conflicts of interest aren’t just an “employment issue”-they’re also a governance issue for your new business.

For example, if you later bring on a co-founder or investor, they’ll want comfort that your business isn’t at risk because of your day job obligations.

Depending on the business and the people involved, it may be worth adopting a Conflict Of Interest Policy so the rules are clear as the company grows.

What Legal Documents Should You Put In Place (So You Don’t Trip Up Later)?

When your business starts as a “side project”, it’s easy to keep everything informal. But informality is where misunderstandings and disputes thrive-especially when you’re balancing employment obligations at the same time.

Here are common legal documents to consider as you start operating:

• Non-Disclosure Agreement (NDA): useful when you’re discussing your business idea with developers, contractors, potential partners, or suppliers-so you can share information without losing control of it. A Non-Disclosure Agreement helps set clear confidentiality expectations.
• Customer Contract or Terms and Conditions: if you’re selling services or products, you’ll want something in writing that covers scope, fees, payment terms, limitations of liability, and what happens if things change.
• Contractor Agreement: if you’re outsourcing work (design, development, marketing), you’ll want to ensure IP ownership is properly assigned to your business and confidentiality is covered.
• Privacy Policy: if you collect personal information (emails, phone numbers, addresses, enquiries through a website), you should have a Privacy Policy explaining how you collect, use, and store data.
• Website Terms: if you operate online (even a simple landing page), terms can help set rules for site use and reduce misunderstandings.
• Employment Contract: if your new company hires staff (even part-time), having a compliant Employment Contract helps clarify expectations and reduce disputes.

A Quick Note On Australian Consumer Law

If your new company sells to customers, you’ll need to comply with the Australian Consumer Law (ACL). This affects how you advertise, what you promise, how you handle complaints, and when refunds or remedies might apply.

This matters even if your business is “small” or still a side hustle. Compliance tends to be much easier (and cheaper) when you set things up properly at the beginning.

How To Reduce Risk While You’re Still Employed

To keep things practical, here’s a simple risk-reduction checklist that works for many founders:

• keep a clear separation between work time and business time
• avoid overlapping customers, suppliers, or services where possible
• don’t use any employer resources (devices, systems, IP, data)
• document ownership and roles early (especially if there’s a co-founder)
• put basic contracts in place before you take money from customers
• get advice early if your side business might be seen as competitive

This approach doesn’t slow you down-it usually speeds you up, because it prevents distractions like disputes, rework, and uncomfortable conversations later.

Key Takeaways

• In many cases, you can start a company while working for another employer in Australia, but you need to manage conflict of interest and contract risk carefully.
• Your employment contract may include exclusivity, confidentiality, intellectual property, and restraint clauses that affect what you can build and how you can operate.
• Keep your side business separate from your day job: avoid using work time, work equipment, workplace data, or internal processes.
• If you’re incorporating, set your foundations properly (structure, constitution, ownership, governance) so you don’t create future disputes or confusion.
• Strong legal documents-like NDAs, customer terms, privacy policies, and employment contracts-help protect your new company as it grows.
• If your side business might be seen as competing with your employer, getting legal advice early can save you a lot of stress (and protect both your job and your startup).
