Australia's gig economy has exploded in recent years. Whether you are driving for Uber, picking up tasks on Airtasker, delivering for DoorDash, freelancing on Upwork, or running a side hustle on Etsy, the ATO considers you a small business operator — and that comes with a stack of tax obligations that many gig workers only discover at tax time. This guide covers everything you need to know to stay compliant and minimise your tax bill.
Do You Need an ABN?
If you are earning income from gig work, the answer is almost certainly yes. An Australian Business Number (ABN) is required for anyone carrying on an enterprise, and the ATO takes a broad view of what constitutes an enterprise. Regular gig work — even as a side hustle alongside a day job — typically qualifies.
Without an ABN, any business that pays you is required to withhold 47% of the payment under the "no ABN withholding" rules. That is a punishing rate that you would need to wait until tax time to recover. Getting an ABN is free and takes about 10 minutes through the Australian Business Register website.
Once you have an ABN, you are operating as a sole trader by default. This means your gig income is added to your employment income (if any) and taxed at your marginal rate. Use our self-employed tax calculator to estimate your total tax liability when combining employment and gig income.
GST: The $75,000 Threshold (With One Big Exception)
You must register for GST if your annual turnover from all business activities exceeds $75,000. Below that threshold, GST registration is optional. However, there is one critical exception: ride-sharing and taxi services require GST registration from the first dollar, regardless of turnover.
This means that even if you only drive for Uber on weekends and earn $8,000 a year, you must register for GST, charge GST on every fare, and lodge quarterly Business Activity Statements (BAS). This catch surprises many casual rideshare drivers and is one of the most common compliance failures the ATO targets.
For other gig work — Airtasker tasks, freelance writing, graphic design, delivery driving (not ride-sharing) — you only need to register for GST once you cross the $75,000 threshold. If you are close to that line, it may be worth registering voluntarily so you can claim back the GST on your business expenses. Our GST calculator can help you understand the impact of GST on your pricing and cash flow.
What Can You Claim as Deductions?
The good news for gig workers is that you can deduct expenses that are directly related to earning your gig income. The key is keeping records — the ATO requires receipts or records for every deduction over $10, and you need to be able to show a clear connection between the expense and your income-earning activity.
Common deductions for gig workers include:
- Vehicle expenses: For rideshare and delivery drivers, you can claim fuel, insurance, registration, maintenance, and depreciation using either the logbook method or the cents-per-kilometre method (85 cents per km for FY2025-26, capped at 5,000 km). The logbook method typically delivers larger deductions for high-mileage drivers.
- Phone and internet: The business-use portion of your phone plan and home internet is deductible. If you use your phone 60% for gig work, you can claim 60% of the cost.
- Equipment and tools: Cameras, laptops, software subscriptions, and any other equipment used for your gig work. Items under $300 can be immediately deducted; items over $300 are depreciated over their effective life.
- Platform fees and commissions: The 20% to 30% that Uber, Airtasker, or other platforms take from your earnings is a deductible business expense.
- Home office expenses: If you work from home (common for freelancers and Airtasker providers), you can claim a portion of your rent, electricity, and internet using the ATO's fixed-rate method of 67 cents per hour.
Quarterly BAS Obligations
If you are registered for GST, you must lodge a BAS each quarter and remit any GST collected to the ATO. The quarterly due dates are:
- July to September: due 28 October
- October to December: due 28 February
- January to March: due 28 April
- April to June: due 28 July
Even if you are not registered for GST, the ATO recommends lodging a voluntary BAS if you are making PAYG instalments on your gig income. Setting aside 25% to 30% of your gig earnings each week into a separate bank account is a sensible habit that prevents cash flow crises at BAS time.

Superannuation: The Hidden Gap
Unlike employees, gig workers do not receive compulsory superannuation contributions from the platforms they work for. Uber does not pay your super. Airtasker does not pay your super. This means gig workers are entirely responsible for their own retirement savings.
You can make voluntary super contributions and claim a tax deduction for concessional contributions up to $30,000 per year. At the 15% tax rate inside super versus your marginal rate of potentially 30% to 45% outside it, this delivers a meaningful tax saving while building your retirement balance.
If gig work is your primary income, failing to contribute to super could leave you dramatically underfunded at retirement. Model the long-term impact using our superannuation calculator and set up automatic transfers to your super fund.
The ATO Data-Matching Program
If you are thinking about not declaring your gig income, think again. The ATO has sophisticated data-matching programs that collect transaction data directly from platforms like Uber, Airbnb, Airtasker, eBay, and dozens of others. In 2024-25, the ATO matched data from over 100 sharing economy platforms covering more than $1 billion in transactions.
The ATO also monitors bank account deposits, compares reported income to lifestyle indicators, and uses AI-driven risk profiling to identify potential non-compliance. Penalties for failing to declare income can include fines of up to 75% of the tax shortfall for intentional disregard, plus interest charges backdated to the original due date.
Sole Trader vs Company Structure
If your gig income is growing beyond a side hustle and into serious money — say, over $100,000 per year — you might consider operating through a company structure instead of as a sole trader. A company pays a flat 25% tax rate (for base rate entities) regardless of how much it earns, which is lower than the 30% to 45% individual rates that apply to higher incomes.
However, a company structure adds complexity and cost: annual ASIC fees, separate tax returns, potential fringe benefits tax issues, and the requirement to pay yourself a reasonable salary. For most gig workers earning under $100,000, the sole trader structure is simpler and more cost-effective. Our sole trader vs company calculator helps you compare the two structures side by side.
The Bottom Line
Gig work offers flexibility and freedom, but it comes with real tax responsibilities. Get an ABN, understand your GST obligations, keep meticulous records of your expenses, set aside money for tax each week, and do not forget about super. The ATO is watching the gig economy more closely than ever, and getting it right from the start is far cheaper than fixing mistakes later.
