How to Start a Tradie Company in Australia (2025 Guide)

If you're a tradie thinking about starting your own company — whether that's transitioning from being an employee, going out on your own as a sole trader first, or upgrading your existing business structure — this guide covers the full picture.

We'll walk through exactly what's involved in starting a tradie company in Australia, what it costs, and what most people get wrong the first time around.

What Does "Starting a Tradie Company" Actually Mean?

In everyday language, people use "company" to mean any small business. But in Australia, it has a specific legal meaning: a Pty Ltd (Proprietary Limited) registered with ASIC. This is different from operating as a sole trader, which is just you trading under your own name or a registered business name.

When you start a tradie company:

• The business is a separate legal entity from you personally
• It has its own ABN, bank account, and tax obligations
• Your personal liability for business debts is generally limited
• The company pays the small business corporate tax rate (25%), not your personal income tax rate

Many tradies use "company" loosely to mean their business overall. If you're just starting out and want to get trading quickly, a sole trader structure is simpler. But if you're ready for the full Pty Ltd structure, read on.

Before You Start: Make Sure the Timing Is Right

A tradie company structure makes sense when at least one of the following applies:

Your profits are consistently above $100,000–$120,000 per year. The 25% company tax rate versus the 34.5–47% personal rate represents real money at this level. Below this, the extra setup and accounting costs often outweigh the tax savings.

You're planning to hire employees. A company structure creates clearer legal separation when you're responsible for payroll, super, and workers compensation.

You're pursuing commercial contracts. Many commercial clients and head contractors prefer working with a registered company. It signals stability and provides clearer legal standing on both sides.

Your personal asset exposure worries you. If you own a home, have investments, or simply want to protect your personal finances from business risk, a company limits that exposure significantly.

You want to bring in a business partner. Companies are far easier to structure for shared ownership than sole trader arrangements.

If you're just starting out and none of the above applies yet, consider starting as a sole trader and transitioning to a company once your business grows. You'll save money on setup and accounting while you're building.

How to Start a Tradie Company: The Complete Process

Step 1: Plan Your Company Structure

Before you register anything, work out how the company will be owned and run.

Directors: The people who manage the company's day-to-day affairs. There must be at least one director who is an Australian resident. As the working tradie-owner, you'll almost certainly be a director.

Shareholders: The people who own shares in the company. In a simple tradie company, this is often just you. But it could also include a spouse or a family trust, which may have tax planning advantages.

Constitution vs replaceable rules: Every company operates under a set of rules. You can use the default "replaceable rules" under the Corporations Act (simpler, no cost) or have a custom constitution drafted (more control, costs $500–$2,000+ through a lawyer). For most simple tradie companies, the replaceable rules are sufficient.

Associated trust structure: Some tradies set up a discretionary family trust alongside the company. The company acts as trustee, and the trust distributes income. This can reduce overall tax but adds complexity. Discuss with your accountant whether this makes sense for your situation.

Step 2: Choose and Check Your Company Name

Your company name must end in "Pty Ltd." Check that it's available through the ASIC company name register at asic.gov.au. Company names are unique across Australia — unlike business names, which can exist in multiple states.

Common naming approaches for tradie companies:

• Your name + trade: "Turner Electrical Pty Ltd"
• Location + trade: "Bayside Plumbing Pty Ltd"
• Brand name: "BlueLine Building Services Pty Ltd"

You can also register a separate trading name (business name) if you want your brand to appear differently from your legal company name. For example, "Coastline Electrical Pty Ltd" might trade publicly as "Coastline Electrical" without the Pty Ltd.

Step 3: Register with ASIC

Register your company online at asic.gov.au. The registration fee is currently around $590. You'll need to provide:

• Company name
• Registered office address (a physical Australian address — can be your accountant's office)
• Principal place of business
• Names, addresses, and dates of birth of all directors
• Names and addresses of all shareholders, plus the number of shares each holds

ASIC processes the registration and issues a Certificate of Registration and an ACN (Australian Company Number). Your company legally exists from this point.

Step 4: Apply for an ABN and Register for GST

With your ACN in hand, apply for an ABN through the Australian Business Register (abr.gov.au). The company's ABN is separate from any ABN you held as a sole trader.

Register for GST at the same time if your expected turnover is over $75,000. As an active tradie business, you almost certainly need GST registration. This allows you to:

• Charge GST on your invoices
• Claim back GST on business purchases (materials, tools, fuel, subcontractors)
• Lodge quarterly BAS to reconcile what you've collected and paid

Step 5: Open a Company Bank Account

This is non-negotiable. The company must have its own bank account in the company's name. Do not mix company money with your personal finances — this can undermine the liability protection of the company structure.

Most major Australian banks offer business accounts for companies. Newer options like Macquarie Business Banking and Relay have more competitive fee structures for small companies.

Step 6: Set Up Accounting Software

Get your accounting system in place before you start trading through the company. Xero is the dominant choice among Australian tradies and their accountants — it integrates with job management tools (ServiceM8, Tradify, Fergus) and makes BAS preparation straightforward.

MYOB AccountRight is the stronger option if you have complex job costing needs — tracking costs, labour, and materials against individual projects.

Connect your company bank account to your accounting software via bank feeds so every transaction appears automatically.

Step 7: Register as an Employer (If You Have Employees)

If you're paying wages — including to yourself as a director-employee — you need to:

• Register as a PAYG withholding employer with the ATO
• Set up Single Touch Payroll (STP) reporting (mandatory for all employers)
• Register for workers compensation insurance in your state

Your accounting software handles STP reporting automatically each pay run.

Step 8: Ensure Your Licences Are in Order

Trade licences in Australia are typically issued to individuals, not companies. This is a crucial point that many tradies miss when setting up a company. Depending on your state and trade, you may need to:

• Obtain a separate company contractor licence
• Ensure that a suitably licensed individual (usually you, as a director) is nominated as the responsible person for the company's work
• Notify the relevant licensing body of the change in business structure

Check with the relevant authority in your state — VBA (Victoria), NSW Fair Trading, QBCC (Queensland), etc. — to confirm what applies to your specific situation.

Step 9: Update Your Insurance

All your business insurance needs to be in the company's name, not your personal name. This includes:

• Public liability insurance
• Tools and equipment insurance
• Professional indemnity (if relevant to your trade)
• Workers compensation (mandatory if employing staff)

Contact your insurer to update existing policies or take out new ones in the company name.

How Much Does It Cost to Start a Tradie Company?

Budget roughly $2,000–$5,000 to get a tradie company properly set up, plus ongoing accounting and compliance costs of around $3,000–$6,000 per year depending on the complexity of your business.

Common Mistakes When Starting a Tradie Company

Mixing personal and company money. Drawing cash from the company without properly recording it as a salary or dividend creates tax problems and can personally expose you to the company's debts. Keep it separate, always.

Forgetting about licences. Your existing individual trade licence may not automatically extend to your company. Confirm this before the company starts trading.

Not paying yourself super. As a company employee (even if you're also the director and sole shareholder), you're entitled to superannuation. Failing to pay it is a breach of your obligations and can result in penalties through the Superannuation Guarantee Charge.

Underestimating the admin overhead. A company has more compliance requirements than a sole trader — annual ASIC returns, a company tax return separate from your personal return, director duties, and more rigorous record-keeping. Budget time and money for this upfront.

Choosing the wrong accountant. Tax law for small companies has nuances that not all accountants understand equally well. Find an accountant who specifically works with trade businesses and small companies — their advice will save you more than their fee.

The Bigger Picture

Starting a tradie company is a significant step. Done right, it can reduce your tax, protect your personal assets, and help you build a business that's more attractive to larger clients. Done poorly — wrong structure, missed licences, confused finances — it creates problems that can take years to untangle.

Take the time to get proper advice before you register, set up your systems properly from day one, and treat the company as the separate entity it legally is. The tradies who run successful companies long-term are the ones who respect the structure they've set up.
