ABN
Setting money aside so your ABN tax bill doesn't sting
Updated 2026-06-16
With an ABN, no tax is taken from your payments during the year, you get the full amount and the bill lands at tax time. The mistake that hurts every year: spending it all, then owing the ATO thousands in one go. The fix is a habit, not a calculation.
The 20% rule
- Open a separate savings account (free, with your Australian bank).
- Every time you get paid, move 20% of it into that account and don't touch it.
- At tax time, your bill is 15% of your net income (revenue minus expenses), usually less than what you saved, so the rest is a bonus.
Track your deductions as you go, every business kilometre, fuel receipt, phone bill and bag lowers your taxable profit, which lowers the bill. And you only deal with GST if your ABN turnover passes $75,000 (rideshare drivers are the exception, they register from the first dollar).
FAQ
- Is 20% enough to set aside?
- For most backpackers under $45,000 total income, yes, your rate is 15%, so 20% leaves a buffer. If you also have wages and cross $45,000, save 25%.
- Do I charge GST on Uber Eats?
- Only if your ABN turnover passes $75,000 (food delivery). Rideshare drivers must register for GST from the first dollar.
