Do I Need an Accountant as a Sole Trader in WA?

← Back to Blog

As a sole trader in Western Australia, you wear a lot of hats. You're the salesperson, the service provider, the admin manager — and often, the accountant too. The question is: should you be?

There's no one-size-fits-all answer. For some sole traders, managing their own basic accounts makes perfect sense. For others, it's costing them money, time, and sleep — often without them realising it.

In this guide we'll give you a clear, honest picture of when you can handle it yourself, and when it's time to bring in a Perth sole trader accountant.

What Are Your Tax Obligations as a Sole Trader in WA?

Before deciding whether you need an accountant, it helps to understand what you're actually required to do. As a sole trader in Western Australia, your obligations typically include:

• Annual income tax return — reporting your business income and expenses in your personal tax return
• GST registration and BAS lodgement — if your annual turnover exceeds $75,000, you must register for GST and lodge a Business Activity Statement (BAS), usually quarterly
• PAYG instalments — once your tax liability reaches a certain threshold, the ATO may require you to pay tax in instalments throughout the year
• Superannuation — you're responsible for your own super contributions as a sole trader
• Record keeping — you must keep financial records for at least five years
• Payroll obligations — if you have employees, you must withhold PAYG tax, pay superannuation, and comply with Single Touch Payroll (STP) reporting

When Can You Manage It Yourself?

You may be fine without an accountant — at least for routine matters — if all of the following apply to you:

• Your annual turnover is under $75,000 (no GST registration required)
• You have simple, consistent income from one or two clients
• You have minimal deductible expenses that are easy to track
• You keep records diligently throughout the year
• You have no employees
• You're comfortable using myTax or basic accounting software

Even in this scenario, getting a professional to at least review your first return is worthwhile — it's easy to miss deductions or make structural mistakes early on that become costly later.

When You Should Absolutely Use an Accountant

There are situations where attempting to go it alone as a sole trader in WA is a false economy. Here's when you need professional help:

Your turnover is over $75,000

Once you cross the GST threshold, you need to register, charge GST to clients, and lodge BAS returns. The rules around what GST applies to, input tax credits, and reporting periods can be complex. Errors attract ATO interest and penalties.

You have business expenses that are hard to categorise

Home office costs, vehicle expenses, tools, travel, professional development — the rules around what you can and can't claim are more nuanced than most people realise. An experienced accountant will ensure you claim everything you're legally entitled to without overstepping ATO guidelines.

You're mixing personal and business finances

If your personal and business transactions run through the same account, separating them at tax time is time-consuming and error-prone. An accountant can help you set up proper structures from the start.

You're thinking about taking on employees

The moment you hire staff, your obligations expand significantly: PAYG withholding, superannuation, Single Touch Payroll, workers' compensation, and potentially payroll tax. Getting this wrong is costly. A payroll specialist pays for themselves.

You're not sure whether to stay as a sole trader or incorporate

There's a point in most growing businesses where the sole trader structure stops being tax-efficient. Whether and when to incorporate as a company, set up a trust, or restructure is one of the most valuable questions a Chartered Accountant can help you answer.

You're behind on lodgements

If you've missed a tax return or BAS, the ATO's Failure to Lodge (FTL) penalties can escalate quickly. A registered tax agent can often negotiate with the ATO on your behalf and minimise penalties.

What Does a Sole Trader Accountant Actually Do For You?

A good sole trader accountant in Perth doesn't just lodge your tax return once a year. They act as a financial partner who helps you:

• Structure your business tax-efficiently from the start
• Claim every legitimate deduction — including ones you didn't know about
• Stay on top of BAS lodgements and avoid penalties
• Plan for your tax bill so there are no nasty surprises
• Set up Xero or another accounting system so your records are clean
• Understand your numbers and make better business decisions
• Scale up confidently when the time comes to employ staff or restructure

How Much Does a Sole Trader Accountant Cost in Perth?

The key thing to remember is that accounting fees are tax deductible — and a good accountant will typically save you more than their fee through better deductions and tax planning.
