Your complete guide to starting a side hustle in Australia
Got an idea that could earn you extra income, but not quite sure where to begin?
Our free Beginner’s Guide to Starting a Side Hustle walks you through the practical steps involved, from choosing your idea and getting set up to finding customers, managing your money and understanding your tax obligations.
Whether you want to earn a little extra on the side or test an idea that could become something bigger, this guide will help you get started with fewer question marks.

Your side hustle might be small. The tax still counts.
Once your side hustle starts earning money, it can affect your tax position even if you also have a regular job.
That means keeping track of what you earn, what you spend and how much tax you may need to pay. It is not the most exciting part of starting something new, but leaving it until tax time is usually worse.
TaxTank helps you manage your side hustle as you go, so you can spend less time wondering about tax and more time seeing where your idea takes you.

Know where you stand before tax time
Your employer may already withhold tax from your salary, but that does not automatically cover the extra income from your side hustle.
TaxTank brings your PAYG income and sole trader activity together to calculate your estimated overall tax position.
As your income and expenses change, TaxTank updates the result so you can:
- See how your side hustle affects your tax
- Understand whether you may have tax to pay
- Keep track of deductible business expenses
- Prepare for tax before the financial year ends
- Avoid a nasty surprise after lodging your return
You do not need to calculate everything yourself. TaxTank applies the Australian tax rules in the background.
Everything you need to manage your side hustle
You can now manage your side hustle seamlessly with auto invoicing, business reporting and integrated logbooks, as well as smart tax tools to manage deferred losses and the ATO rules to offset tax.
Send invoices and track payments
Create and send invoices, then match payments from your connected bank accounts so you can see what has been paid and what is still outstanding.
Track income and expenses
Bring transactions into TaxTank through eligible bank feeds, categorise business expenses and create rules for regular transactions.
Keep your receipts together
Attach receipts and supporting documents directly to your transactions instead of hunting through emails and folders at tax time.
Manage GST and BAS
If you are registered for GST, TaxTank tracks the GST collected and paid and prepares the information needed for your BAS.
Claim vehicle & home office expenses
Keep business vehicle records, complete your logbook and record working-from-home hours using the built-in Home Office Diary.
Manage assets and depreciation
Record business equipment, calculate depreciation and manage assets within the small business pool.
Track business loans
Keep business loan balances, repayments and interest connected to the activity they relate to.
Manage more than one idea
Got more than one side hustle on the go? Sole Tank lets you manage up to six sole trader businesses operating under your ABN.
Include foreign business income
If an overseas client pays you for sole trader work, TaxTank can convert the income to Australian dollars and include it in your estimated tax position.
Sole Tank is just $108 per year
That is equivalent to $9 per month, paid annually.
Your subscription includes the tools to manage up to six sole trader businesses, and the price does not increase when your side hustle earns more.
You can also add Work Tank if you want to connect your PAYG income and work-related deductions with your sole trader tax position.
