Running a small business in Australia can be incredibly rewarding—but let’s be honest, it comes with its fair share of responsibilities. One of the most crucial (and sometimes confusing) aspects? Your tax obligations.
If the world of tax feels like a maze, don’t worry—you’re not alone. Today, we’re breaking things down into bite-sized, easy-to-digest info so you can feel confident navigating the ATO’s requirements for your business.
Why Understanding Tax Obligations Matters
Before we dive into the details, you might be wondering: “Why does this matter so much?”
Here’s the deal: Understanding your business tax obligations helps you:
- Avoid penalties and interest from the ATO
- Stay cash-flow positive
- Plan for growth with confidence
- Make smarter financial decisions
Now let’s explore what tax obligations you need to know as an Australian small business owner.
1. Get Your Business Structure Right
First things first—how your business is structured affects everything from your tax rate to your reporting duties. Common business structures in Australia include:
- Sole trader: Simple, cheap to set up, but the owner is personally liable for debts.
- Partnership: Two or more people share responsibilities and income. Each partner pays tax on their share.
- Company: A separate legal entity. You pay tax at the company rate (currently 25% for base rate entities).
- Trust: Often used for asset protection and tax planning. Requires careful setup and ongoing management.
Choosing the right structure isn’t just a legal formality—it can influence how much tax you pay and how complicated your reporting will be. If you’re unsure, chat with a qualified accountant who can tailor advice to your situation.
2. Register for the Right Taxes
Depending on your business, you may need to register for one or more types of taxes with the ATO:
- Australian Business Number (ABN): Almost all businesses need one. It’s like your business ID.
- Tax File Number (TFN): Sole traders use their personal TFN. Companies need a separate one.
- Goods and Services Tax (GST): You must register if your turnover is $75,000 or more. Once registered, you’ll add 10% GST to your sales and lodge Business Activity Statements (BAS).
- Pay As You Go (PAYG) withholding: If you have employees, you need to withhold tax from their wages and report it to the ATO.
- PAYG instalments: These are prepayments of your own income tax, often required once you earn over a certain threshold.
- Fringe Benefits Tax (FBT): Applies if you provide perks to employees, like a company car or meal allowances.
Feeling overwhelmed already? Don’t stress. When you start your business or register new staff, the ATO provides guidance to get your tax setup sorted properly.
3. Keep Good Records
One of the simplest but most powerful things you can do for your business is to keep accurate financial records. This isn’t about spreadsheets galore or fancy accounting software—although those help too. It’s about documenting your income and expenses clearly.
Here’s what you should keep track of:
- Sales and income (including invoices issued)
- Business expenses (keep those receipts!)
- Employee records, including pay slips and super payments
- BAS and tax returns filed
The ATO generally requires you to keep these records for at least five years. Not only does this help if you’re audited—it also makes lodgment season a whole lot easier!
4. Lodge on Time: Know Your Dates
Timing is everything when it comes to tax.
Some important lodging and payment dates include:
- BAS – due quarterly (or monthly for some businesses)
- Income tax return – due annually, usually by October 31 if you’re self-lodging
- FBT return – due May 21 each year if applicable
- Super guarantee payments – due quarterly for employee contributions
Pro tip: Missing these deadlines can lead to penalties and interest charges. A great way to stay on track? Set calendar reminders or work with a registered tax agent who can manage lodgment for you.
5. Make Super Contributions
If you employ staff (or even pay yourself as a director), you’re likely required to make superannuation contributions. In most cases, this means currently paying at least 11.5% (12% from 1st July 2025) of an employee’s ordinary time earnings into a super fund.
Key things to know:
- Super is due quarterly, but paying more frequently helps with cash flow management
- Payments must go through a clearing house like the ATO’s Small Business Superannuation Clearing House
- Late payments could mean losing your deduction and having to pay extra charges
6. Claim What You’re Entitled To
No one wants to pay more tax than they need to. That’s where deductions come in. You can reduce your taxable income by claiming business-related expenses, like:
- Office rent and utilities
- Software subscriptions and tools
- Vehicle expenses (if used for work)
- Marketing and advertising costs
- Professional services (like legal or accounting fees)
Of course, the expense must be directly related to earning income. So, that weekend getaway? Probably not deductible—unless it was for a legitimate business retreat (and you can prove it).
7. Engage a Tax Professional
Let’s face it—Australian tax rules can be tricky. So even if your business is small, having an accountant in your corner can be a game-changer.

- Your business complies with the latest tax laws
