Sole traders and freelancers in Australia who invoice their own clients and have to put money aside for tax themselves.
Como funciona
- Label the year, for example "FY25 sole trader".
- Enter what you invoiced and your deductible expenses.
- Say whether you are registered for GST - if you are, your invoices include it.
- Read the amount to set aside, and the weekly figure to move to a separate account.
O que você ganha
- Calculates the real percentage of income an Australian sole trader should set aside for tax, bracket by bracket, instead of the flat 30% rule of thumb that usually sets aside the wrong amount.

Perguntas frequentes
Is my financial data safe?
Yes, all calculations happen in your browser. No data is sent to or stored on our servers.
Does this tool file my tax return or give legal advice?
No, it only calculates a suggested set-aside amount based on the figures you enter. It doesn't lodge anything or account for all possible deductions or offsets.
What if the tax rates change?
The tool uses a named rate table and prints that name with every result, so you can see which year's rates were applied and check if they're current.
