Running a small business is no small task. Between managing operations, looking after staff, and delivering value to customers, it’s easy to lose track of tax obligations until it’s too late. At A Plus Accountant, we regularly assist business owners in untangling preventable tax issues that could have been easily sidestepped with the proper support.
To help you stay on track, here are seven tax mistakes we frequently come across, along with practical steps you can take to avoid them.
1. Poor Record-Keeping
One of the most common traps business owners fall into is failing to maintain accurate financial records. Whether it’s lost receipts or relying purely on bank statements, insufficient documentation can lead to issues with the ATO — especially when claiming deductions for work-related travel, car usage, or working from home.
How to avoid it:
Switch to a cloud-based accounting system or a mobile app that allows you to log expenses and upload receipts in real time. This not only helps with compliance but also provides a clearer picture of your business finances throughout the year.
2. Mixing Business with Personal Spending
Blurring the lines between personal and business expenses might seem harmless. Still, it creates a tangle of confusion at tax time. It also makes it harder to claim legitimate deductions and could raise eyebrows during a review.
How to avoid it:
Open a separate business bank account and use it solely for income and expenses related to your business. This makes bookkeeping far more straightforward and more transparent.
3. Missing Superannuation Deadlines
Many small business owners are unaware that if super is paid after the due date, it’s no longer tax-deductible. Beyond losing the deduction, you could also face penalties or interest charges.
How to avoid it:
Mark your calendar with all the quarterly super payment deadlines and set reminders well in advance. Automating payments where possible can also reduce the risk of falling behind.
4. Claiming GST Incorrectly
Claiming GST on transactions that are GST-free is a red flag for the ATO and may result in audits or adjustments. This often happens with bank fees, overseas services, or misconfigured software settings.
How to avoid it:
Review your GST reports at the end of each BAS cycle. Make sure you understand which items are GST-free and regularly update the tax codes in your accounting system.
5. Failing to Plan Ahead for Tax
When business income suddenly increases, many owners are caught unprepared at tax time. Without regular planning, you might face a large, unexpected bill that impacts cash flow or growth.
How to avoid it:
Put aside a percentage of your earnings each month into a separate tax savings account. Better yet, book quarterly catch-ups with your accountant to forecast obligations and adjust plans early.
6. Overlooking Legitimate Deductions
Every dollar counts in small business, and missing out on deductions — such as depreciation, fuel, or business-related phone use — means you’re probably paying more tax than necessary.
How to avoid it:
Speak to a tax professional who understands your industry and can provide a checklist of deductions you’re entitled to claim. Tailored advice can significantly reduce your tax liability here.
7. Trying to Handle It All Yourself
Going it alone might feel like the budget-friendly option, but many business owners end up losing more than they save. Mistakes, overlooked entitlements, or poor structuring can all result in significant long-term costs.
How to avoid it:
Engage a qualified tax agent or accountant who understands small business. Professional advice ensures you remain compliant, seize every available opportunity, and operate under the most effective structure to achieve your goals.
