Ready to find the right sole trader accountant?
If you’re hunting for the best sole trader accountant in Australia, there’s a good chance you’re already feeling the pressure. Maybe tax time keeps you up at night, maybe your “simple” business has turned into a mess of invoices, BAS, and bank feeds and now you’re worried that choosing the wrong accountant will cost you time and money.
This guide will walk you through exactly
- How to choose the right accounting service as a sole trader
- What to look for
- What it should cost so you can use to compare providers side by side.
When should a sole trader actually hire an accountant?
Sole traders don’t need an accountant on day one. But there is a point where doing it yourself stops saving money and starts costing you.
You should seriously consider hiring an accountant when:
- Your income is no longer “side hustle” money, it’s a real, growing business
- You’re registered (or about to register) for GST and need regular BAS lodgements
- You’re paying contractors or staff, or thinking about it
- You’re claiming a lot of business expenses and aren’t 100% sure what’s allowed
- You’ve received an ATO notice, or you’re anxious you might trigger one
- Bookkeeping and tax are taking time away from billable work
At that stage, the question isn’t “Can I keep doing this myself?”
It’s:
“Is my time, stress and risk worth more than the cost of a good accountant?”
If the honest answer is yes, it’s time to start looking.
What makes a good sole trader accountant?
Once you’ve decided you’re done with DIY, the next step is filtering out “any accountant” from the right accountant for a sole trader.
Here are the non-negotiables.
1. Sole traders are a core client type, not an afterthought
You want someone who works with sole traders every day, not just companies and bigger SMEs.
Look for:
- Services that clearly mentions sole traders, freelancers, tradies, consultants, creatives, online businesses
- Examples or case studies that sound like your situation
- Questions about how you work (income streams, tools, typical expenses), not just generic entity questions
If everything they talk about is companies, boards, and CFOs, they’re probably not the best fit.
2. Clear, fixed-fee pricing with a defined scope
For sole traders, unpredictable hourly billing is a recipe for bill shock.
A strong provider will:
- Offer fixed-fee or package pricing (monthly or annual)
- Spell out exactly what’s included: tax return, BAS, bookkeeping, advice, software
- Be upfront about what costs extra (e.g. amendments, complex advice, cleanup work)
Quick test:
Ask for a written outline of “What’s included in this fee, and what would be an additional charge?”
If the answer is vague, move on.
3. Proactive tax and compliance support (not just form-filling)
You’re not paying just to have forms lodged. You’re paying for someone to keep you compliant and help you avoid overpaying tax.
A good sole trader accountant will:
- Talk about planning ahead, not just cleaning up last year
- Explain typical deductions for your type of work (tools, home office, vehicle, software, marketing, professional fees, etc.)
- Be explicit that they stay on the right side of ATO rules, no gimmicks, no “creative” shortcuts
If all they talk about is “lodging returns”, their mindset is too narrow.
4. Strong cloud accounting and automation skills
An accountant who still relies on emailing spreadsheets back and forth will slow you down.
Look for someone who:
- Works confidently with cloud accounting software (e.g. Xero)
- Can help you set up or clean up bank feeds and rules
- Encourages tools like receipt capture rather than manual data entry
That’s how you get your evenings back instead of reconciling transactions line by line.
5. Service you can actually rely on
Technical skills are useless if you can’t get a straight answer when you need one.
Check:
- Response times: Ask, “How quickly do you usually reply to sole trader clients?”
- Point of contact: Will you have a go-to person, or a different name every time?
- Communication style: Do you feel talked down to, rushed, or genuinely supported?
How Much Does It Cost to Set Up as a Sole Trader in Australia?
How much does a sole trader accountant cost?
If you’re a sole trader in Australia, you’ll usually see two types of costs:
- A once-a-year fee for your sole trader tax return
- An ongoing package fee if you want bookkeeping, BAS and support bundled in
Here’s a simple snapshot.
| Service type | What it usually covers | Typical fee range |
| Basic individual tax return (no ABN) | Salary/wage income, standard deductions, electronic lodgement | $150 – $350 |
| Sole trader tax return (with ABN) | Business income & expenses, business schedule, often GST/BAS reconciliation | $400 – $1,500 |
| One-off BAS lodgement | Preparing and lodging a quarterly BAS based on numbers you provide | Roughly $50 – $300 per BAS |
| Ongoing bookkeeping + BAS + tax package | Monthly bookkeeping, quarterly BAS, year-end tax return, software support, Q&A | Often from a few hundred to several hundred dollars per month, depending on volume & complexity |
1. One-off sole trader tax return
If you’re only looking for someone to “do my tax”, you’re usually paying for a sole trader tax return that includes:
- Your individual return
- The business schedule attached to it
- Business income and expense review
- Often some basic help with GST/BAS if you’re registered
Most firms will sit somewhere in the $400–$1,500 range for this, depending on how messy or complex things are, multiple income streams, poor records, or lots of deductions to work through will push you towards the top end.
This option can make sense if:
- You’re still relatively simple (one main activity, low transaction volume)
- You’re comfortable doing your own bookkeeping during the year
- You only want help at tax time, not ongoing support
2. Ongoing fixed-fee packages (what most growing sole traders end up on)
Once you’re GST-registered, growing, or simply sick of doing admin at night, a lot of sole traders move onto fixed-fee packages.
These will typically bundle:
- Bookkeeping (reconciliations, coding transactions)
- Quarterly BAS (if you’re registered for GST)
- Year-end tax return
- Help with cloud accounting software (e.g. setup, cleanup, ongoing support)
- Year-round questions and advice
Because scope varies so much, packages are usually priced as a monthly fee rather than a single number on a webpage. But in practice, it’s common for small businesses and sole traders to pay a few hundred to several hundred dollars per month, depending on:
- Number of transactions and bank accounts
- Whether payroll is involved
- Whether you want just compliance, or advisory as well
What to focus on (more important than the exact number)
Instead of fixating on “Is this too expensive?”, zoom out and look at the value behind the fee.
Consideration | What to look for |
Scope | Is it tax-only, or does it include BAS, bookkeeping, software and advice? |
Predictability | Fixed-fee or package pricing vs open-ended hourly billing and surprise invoices. |
Value over 12 months | How much time, stress and risk does this realistically take off your plate? |
Fit for your situation | Does the package match where your business is now and where it’s heading? |
The goal isn’t to find the cheapest accountant.
It’s to find the one who gives you the best outcome for the fee you’re paying.
Red flags to watch when looking for a sole trader accountant
Just like there are signs you’ve found the right fit, there are also signals you should walk away.
Here are the biggest red flags to keep an eye on:
Red flag | What it looks like | Why it’s a problem |
Vague or shifting pricing | “We’ll just bill you at the end” / no clear scope in writing | You have no idea what you’ll pay until the invoice lands |
Only hourly billing, no estimate | Can’t give even a ballpark for the year | Easy for costs to blow out, hard to budget |
No clear experience with sole traders | They only talk about companies, groups, “corporate clients” | They may miss sole trader-specific issues and opportunities |
Slow or patchy communication | Takes days to reply, hard to get straight answers | You’ll be chasing them when deadlines or ATO letters hit |
Overpromising tax refunds | Lots of talk about “big refunds” before they know your situation | Suggests aggressive or risky tax behaviour |
Reluctance to use cloud tools | Pushes back on Xero or similar, wants everything emailed or on spreadsheets | More manual work, higher error risk, less visibility for you |
No mention of security or data handling | Casual about TFNs, bank data, documents over unsecured email | Puts your sensitive information at unnecessary risk |
Purely reactive mindset | “We’ll talk at tax time” and nothing about planning, check-ins or year-round help | You stay stuck in last-minute mode, not proactive with tax or cash flow |
A good sole trader accountant should make you feel:
- Clear on what you’ll pay
- Clear on what you’ll get
- Confident they know your type of business
- Comfortable asking questions
If you’re feeling the opposite, that’s your cue to keep looking.

FAQs on best sole trader accountant
Three main risks:
- Overpaying tax (missing legitimate deductions, poor timing)
- Underpaying tax or GST (misclassifying, under-reporting, or misapplying GST)
- Admin blowouts (late lodgements, penalties, interest, and lost time you could’ve billed)
I earn Personal Services Income (PSI). How important is it that my accountant understands PSI rules?
Critical. If your income is PSI and you don’t meet the PSI tests, you can’t just split income or claim arbitrary business-style deductions. You need an accountant who can correctly apply the results test, 80% rule and unrelated clients/employment tests, and then structure your deductions and reporting around that or you risk amended assessments and penalties.
They should be able to:
- Reconcile platform payouts back to invoices and bank feeds>
- Deal with fees, chargebacks and foreign currency correctly
- Set up your Xero so that platform income is tracked cleanly for both GST and income tax.
If their answer is “just export a summary from each platform and email it”, they’re not operating at the level you need.
