Frequently asked questions
Is a sole trader taxed differently to a company?
Yes, sole trader profit is taxed at the individual's personal marginal rates, unlike companies which pay a flat corporate tax rate.
Does this include GST?
No, GST is a separate consumption tax; see the GST or BAS calculators on this site for GST obligations.
Should I include superannuation as an expense?
Voluntary super contributions you make for yourself as a sole trader can be deductible; enter profit after any contributions you plan to claim.
