How accounting for side hustles usually works
A good process starts with a quick review: what you do, how you get paid, your structure (often sole trader early on), which platforms you use, current records and any deadlines. From there the work splits into three layers:
1) Immediate triage. Sort out ABN/GST needs, fix urgent lodgements (BAS/tax), connect bank feeds, and separate business spending.
2) Process design. Choose simple software, set a weekly upload routine for receipts, map category rules, and plan a tax set‑aside.
3) Ongoing review. Monthly or quarterly check‑ins to reconcile accounts, lodge BAS if registered for GST, and prepare your year‑end tax return with clear schedules of what was claimed and why.
Australian context to keep in view
- An ABN is free to obtain. You need one if you’re running a business rather than a hobby.
- Register for GST when your GST turnover reaches $75,000 in a 12‑month period or you expect to reach it. Rideshare/ride‑sourcing requires GST registration from the first dollar earned.
- Income from platforms (e.g. delivery apps, freelancing marketplaces, online stores) is taxable. Keep excellent records of payouts, fees and costs.
- Residential rent is generally input‑taxed for GST, but Airbnb/short‑stay income is still assessable for income tax. Get advice if unsure.
- PAYG instalments may start after your first tax return with business income—plan cash flow so instalments don’t sting.
What to compare before you commit
Scope
Confirm it actually covers your side hustle: ABN/GST, bookkeeping setup, BAS, year‑end tax, and simple planning (how much to set aside, when to change structure).
Software fit
Choose a provider fluent in your tools (Xero, QuickBooks, platform exports) and who explains the workflow clearly—what you do weekly vs what they do monthly/quarterly.
Turnaround and communication
Ask when you’ll hear from them, what happens at quarter‑end, and how urgent issues are handled near BAS or tax deadlines.
Commercial fit
Compare fixed‑fee vs pay‑as‑you‑go, inclusions (BAS, tax return, software), and whether you need compliance‑only or brief advisory check‑ins.
Common side hustle scenarios and typical help
- Freelancers and contractors. Invoices, ABN, track software and equipment costs, home‑office percentage, super for yourself, and when to register for GST.
- Creators, eCommerce and marketplaces. Track platform fees and payouts, inventory and shipping, GST on Australian sales, and category rules for ad spend and tools.
- Rideshare and delivery. GST from the first dollar, fuel and maintenance logs, phone and data apportionment, and simple quarterly BAS routine.
- Short‑stay hosting. Income reporting, cleaning and supplies, insurance, depreciation where eligible, and local rules that affect deductibility.
- Tradies moonlighting. Quotes/invoices, materials tracking, tool deductions, vehicle logbooks and when a company or trust may make sense.
Costs and ways to buy
Most accountants for side hustles offer one of two approaches:
- Fixed monthly bundle. Bookkeeping, BAS (if registered), simple advice, and year‑end tax included or discounted.
- Pay‑as‑you‑go. You handle day‑to‑day records; the accountant reviews, lodges BAS or just completes the annual tax return.
The right choice depends on time vs budget. If admin drains weekends, a light monthly bundle is often cheaper than catch‑ups and penalties later.
Best next steps
Write down the outcome you want: ABN set up, clean bookkeeping, a BAS lodged, a tax plan, or structure advice. Gather platform reports and bank statements for the period in question so a provider can scope quickly.
Then shortlist based on fit and clarity. The right accountant explains exactly what will happen in week one, sets expectations around BAS/tax timelines, and shows how your side hustle will stay compliant as income grows.
Frequently asked questions
What does an accountant for side hustles usually do?
They confirm the right setup (ABN/GST), implement simple bookkeeping, advise on what to claim, keep you on top of BAS and tax, and help plan for growth. As income increases they’ll review whether a company, trust or staying as a sole trader delivers the best net outcome.
Do I need GST for my side hustle?
You must register when GST turnover reaches $75,000 in a rolling 12‑month window or you reasonably expect to reach it. Rideshare and ride‑sourcing require GST from the first dollar. If registered, you’ll charge GST where applicable, lodge BAS and claim GST credits on eligible business purchases.
How do I keep records without overcomplicating it?
Open a dedicated account for side hustle income/expenses, use simple software with bank feeds, save receipts as you go, and set a weekly 15‑minute admin block. A basic rulebook (what to keep, what to tag) avoids year‑end guesswork.
When should I switch from sole trader to a company?
Common triggers are higher profit, taking on risk, bringing in staff, or needing a more professional structure for clients. An accountant can model tax savings versus extra costs so you switch at the right time for your situation.
