Running a small business in Australia comes with many rewards — but tax time can quickly become a source of stress if you’re not prepared. The good news is that with the right habits and a clear understanding of your obligations, managing your tax position doesn’t have to be overwhelming.
At MDS Accounting, we work with small business owners every day to help them stay compliant, maximise legitimate deductions, and avoid costly mistakes. Here are five practical tips to help you head into the new financial year with confidence.
Important: The information in this article is general in nature and does not constitute financial, tax, or legal advice. Every business is different. We strongly recommend speaking with a registered tax agent or accountant before making any decisions about your tax affairs.
1. Keep Your Business and Personal Finances Separate
One of the most common mistakes small business owners make is mixing personal and business transactions. This creates headaches at tax time, makes it harder to track deductible expenses, and can raise red flags with the ATO.
What to do:
- Open a dedicated business bank account from day one.
- Use a separate credit or debit card for business expenses.
- Pay yourself a regular wage or director’s fee rather than dipping into the business account informally.
- Reconcile your accounts monthly so you’re never scrambling at year-end.
2. Understand What You Can — and Can’t — Claim as a Deduction
Australian tax law allows businesses to claim deductions for expenses that are directly related to earning assessable income. Understanding what qualifies — and what doesn’t — can significantly reduce your tax bill while keeping you on the right side of the ATO.
Common deductible expenses include:
- Rent and utilities for your business premises
- Business-related travel and vehicle expenses (with correct logbook records)
- Professional development, training, and industry subscriptions
- Marketing and advertising costs
- Accounting, legal, and bookkeeping fees
- Equipment, tools, and technology used for business purposes
3. Stay on Top of GST Obligations
If your business has a GST turnover of $75,000 or more (or $150,000 for non-profit organisations), you are required to register for GST and lodge Business Activity Statements (BAS) with the ATO.
Key GST reminders:
- Lodge your BAS on time — monthly, quarterly, or annually depending on your registration.
- Ensure you have valid tax invoices for all GST credits you intend to claim.
- Review whether any of your sales are GST-free or input-taxed — not everything attracts GST.
- Set aside GST collected in a separate account so you’re not caught short at BAS time.
4. Make the Most of the Instant Asset Write-Off
The Australian Government has, in recent years, offered small businesses the ability to immediately deduct the cost of eligible depreciating assets rather than spreading the deduction over several years. Thresholds and eligibility rules for these concessions are updated regularly in the Federal Budget.
To take advantage of asset write-off provisions:
- Confirm the current threshold and eligibility criteria with your accountant, as these may change each financial year.
- Ensure the asset is first used or installed ready for use within the relevant income year.
- Retain documentation of the asset purchase, including tax invoices and proof of business use.
- Be aware that the write-off applies to the business-use portion of the asset only.
5. Plan Ahead — Don’t Just React at Tax Time
Tax planning is most effective when it’s an ongoing practice, not a last-minute scramble. Business owners who engage with their accountant throughout the year — not just in June — are far better positioned to manage their tax liability and avoid surprises.
Year-round habits that make a real difference:
- Review your profit and loss position quarterly, not just at year-end.
- Keep your bookkeeping up to date and reconcile accounts regularly.
- Consider the tax implications of major business decisions — such as taking on staff, purchasing equipment, or changing your business structure.
- Make superannuation contributions on time to claim the deduction in the correct income year.
- Pay any outstanding PAYG instalments and BAS liabilities before 30 June to ensure timely deductions.
