Setting Up a Tradie Business in Australia: The Complete Step-by-Step Guide

So you've decided to go out on your own. Maybe you've been working for someone else for years, you know the trade inside out, and you're ready to keep more of what you earn. That's a solid foundation. But setting up a tradie business involves a lot more than finding your first customer — and getting the groundwork right in the first few months saves enormous headaches down the track.

This guide walks you through exactly what you need to do, in the right order, with a particular focus on the financial and admin side that most tradies underestimate.

Step 1: Choose Your Business Structure

Before you register anything, decide how your business will be structured. This affects your taxes, your personal liability, and how complicated your admin will be.

Sole trader is the most common starting point. It's cheap and simple to set up, and you report business income on your personal tax return. The downside is that you're personally liable for any business debts — meaning your personal assets can be at risk if something goes wrong.

Company (Pty Ltd) costs more to set up and comes with extra reporting requirements, but it separates your personal finances from the business. Many tradies move to a company structure once they're earning over $100,000 or taking on bigger contracts.

Partnership applies if you're going into business with someone else. You'll both share profits and liability.

For most tradies just starting out, sole trader is the right call. You can always transition to a company later as your business grows.

Step 2: Register Your ABN

An Australian Business Number (ABN) is non-negotiable. Without one, you can't legally invoice clients for your work, and clients will be required to withhold 47% of any payment they make to you under the no-ABN withholding rule.

Registering an ABN is free and takes about 15 minutes through the Australian Business Register at abr.gov.au. Have your tax file number (TFN) ready. You'll receive your ABN immediately if your application is approved.

Step 3: Register for GST (If Needed)

If your annual turnover is expected to exceed $75,000, you must register for GST. Once registered, you charge GST on your invoices, collect it on behalf of the ATO, and claim back the GST you pay on business expenses — which can be significant for a tradie buying materials.

Even if you're under the threshold, some tradies choose to register for GST voluntarily so they can claim back GST on tools, equipment, and vehicle expenses from day one.

Once registered, you'll need to lodge a Business Activity Statement (BAS) either monthly or quarterly, depending on your turnover.

Step 4: Register Your Business Name

If you're trading under any name other than your own legal name, you need to register it with ASIC (Australian Securities and Investments Commission). For example, if your name is Matt Turner and you want to trade as "Turner Electrical Services," that name needs to be registered.

Registration costs around $42 for one year or $98 for three years and can be done online at abr.gov.au. Check that your preferred business name is available before you get attached to it.

Step 5: Get Licensed and Insured

Depending on your trade and the state you work in, you'll need specific licences to operate legally. Requirements vary by state:

• Victoria: Victorian Building Authority (VBA) for builders, plumbers, and some subcontractors
• NSW: Fair Trading contractor licence for work valued over $5,000
• Queensland: QBCC licence for building work
• WA, SA, TAS: Each have their own licensing bodies and requirements

Check the relevant authority in your state before you start taking on jobs. Unlicensed work can result in fines and, more critically, you won't be covered by insurance if something goes wrong.

Insurance is just as important as licensing. At a minimum, tradies should carry:

• Public liability insurance — covers damage to property or injury to third parties caused by your work
• Tools and equipment insurance — covers theft or damage to your gear
• Personal accident and illness insurance — protects your income if you're unable to work

If you're employing anyone, you'll also need workers compensation insurance, which is mandatory in every state.

Step 6: Open a Business Bank Account

This is one of the most overlooked steps when setting up a tradie business, and one of the most important. Mixing your personal and business finances together creates an accounting nightmare at tax time and makes it nearly impossible to understand how your business is actually performing.

Open a dedicated business bank account and run all business income and expenses through it. Most major banks offer business accounts with low fees for sole traders. Some newer options like Thriday combine a business bank account with built-in expense tracking and GST categorisation, which can save significant admin time.

Step 7: Set Up Your Accounting and Bookkeeping System

A good accounting system is what separates tradies who thrive financially from those who work hard and still struggle to get ahead. You need to track:

• Every dollar coming in (invoices and payments)
• Every dollar going out (materials, fuel, tools, subcontractors)
• GST collected and paid
• Superannuation obligations if you have employees

Accounting software does the heavy lifting here. Xero is the most widely used platform among Australian tradies and integrates with job management apps like ServiceM8 and Tradify. MYOB is a strong alternative, particularly for businesses with more complex job costing needs.

For sole traders just starting out, a simpler option like Rounded ($15/month) covers the essentials without the complexity.

Receipt capture is something many tradies get wrong. Every receipt for a business expense — fuel, materials from Bunnings, new tools — needs to be captured and stored. Paper receipts fade, get lost in the glovebox, and rarely survive the wash. An app like Dext or the built-in receipt scanning in your accounting software lets you photograph receipts on the spot and store them digitally.

The ATO requires you to keep records for five years. Getting this right from day one means no scrambling at BAS time and no lost deductions at tax time.

Step 8: Understand Your Tax Obligations

As a sole trader, your business income is taxed at your personal income tax rate. There's no separate tax return for your business — it all flows through your individual return.

The key tax dates to know:

• BAS lodgement: Quarterly (or monthly if your turnover is high). Due 28 days after the end of each quarter.
• Individual tax return: Due 31 October each year (or later if you use a registered tax agent)
• PAYG instalments: The ATO may ask you to pay tax in instalments throughout the year once your income reaches a certain level

Superannuation: If you have employees, you must pay 11.5% superannuation (rising to 12% from 1 July 2025) on their ordinary time earnings, paid quarterly. If you're a sole trader, you're not legally required to pay super for yourself, but doing so is strongly recommended for your retirement.

One thing many new tradies miss: if you operate through a company, the company pays tax at the corporate rate (25% for small businesses), not your personal rate. This can be a significant advantage once your income grows.

Step 9: Set Up Your Invoicing System

Getting paid reliably depends on sending professional, correct invoices promptly. Every invoice should include:

• Your business name and ABN
• The customer's name and address
• A unique invoice number
• The date of the invoice and the due date
• A clear description of the work completed
• The amount charged, with GST shown separately if you're registered

If you're GST-registered, your invoices over $1,000 need to be tax invoices, which means they must include specific information as above.

Most accounting software generates professional invoices automatically and lets you send them from your phone straight from the job site — so payment follows quickly rather than waiting until you get home.

Step 10: Track Your Cash Flow From Day One

Cash flow kills more small tradie businesses than poor trade skills ever will. The pattern is common: work gets done, invoices go out, but payment is slow, and in the meantime materials need to be bought for the next job.

A few habits that protect your cash flow from the start:

• Require a deposit upfront for larger jobs (typically 20–30%)
• Set payment terms of 7 or 14 days, not 30
• Follow up on overdue invoices immediately — don't let them slide
• Keep a buffer in your business account for quiet periods
• Know your break-even point: how much do you need to earn each week to cover all your costs?

Accounting software with bank feeds — where your business transactions appear automatically without manual entry — makes monitoring cash flow much easier and means your numbers are always current.

Common Mistakes When Setting Up a Tradie Business

Not separating finances from day one. Mixing personal and business money makes everything harder. Set up the business account before you take your first dollar.

Underpricing work. Many new tradies price based on what they charged as an employee, forgetting that they're now responsible for their own super, insurance, tools, vehicle, and quiet periods. A proper hourly rate calculation needs to account for all of these.

Ignoring BAS until the last minute. Quarterly BAS surprises are the number one cause of cash flow stress for new tradies. Set aside GST as you receive it — it's never your money to spend.

Not capturing receipts. Every missed receipt is a lost deduction. At the 32.5% tax bracket, a $500 receipt for tools represents $162 in tax saved. Over a year, this adds up to thousands.

Going it alone on tax. A good accountant who works with tradies will save you more than they cost. They'll know the specific deductions available to tradies, keep you compliant, and flag issues before they become problems.

The Financial Foundation That Makes Everything Easier

Setting up a tradie business the right way takes a few hours of admin upfront. The businesses that thrive long-term aren't necessarily the ones with the best trade skills — they're the ones that treat the business side as seriously as the tools side.

Get the structure right, track your money properly, understand your obligations, and use the software available to automate the boring parts. That's what lets you focus on the work itself, grow your business with confidence, and actually hold on to what you earn.
