ABN Profit After Tax Calculator AustraliaUnderstanding ABN Profit After Tax in Australia
As an ABN holder in Australia, your profit after tax is the amount you keep after paying income tax, the Medicare levy, GST obligations, and setting aside superannuation. Unlike PAYG employees who receive a net pay slip, sole traders must calculate their own tax obligations from their gross business income.
What Gets Deducted From Your ABN Income?
Your gross income first has business expenses removed — this includes tools, software subscriptions, home office costs, vehicle expenses, and professional development. If you're registered for GST (required when turnover exceeds $75,000), the ATO collects 10% GST on your sales minus any GST credits from business purchases. Your taxable income is then subject to the individual tax brackets, which in 2025-26 range from 0% on the first $18,200 up to 45% on income above $190,000.
Medicare Levy and Super for Sole Traders
Every Australian taxpayer pays a 2% Medicare levy on their taxable income. If you earn above $93,000 and don't hold private health insurance, you'll also pay the Medicare Levy Surcharge (1-1.5%). While sole traders aren't legally required to pay superannuation, contributing voluntarily at the current rate of 12% ensures retirement savings and provides a tax deduction.

Tips to Maximise Your Take-Home Profit
Claim every legitimate deduction — the ATO allows home office, vehicle, phone, internet, tools, and professional development costs. Lodge quarterly BAS statements on time to avoid penalties. Consider prepaying expenses before June 30 to bring deductions into the current financial year.
