  • Sole traders pay tax at individual rates on business profit. Nothing is withheld from business income, so set money aside for the bill.
  • The small business income tax offset is 16% of the tax on your business share of taxable income, up to $1,000 ($1,000 here).
  • The $1,000 standard deduction for work expenses applies only to salary and wages, not to business income. Claim business expenses before entering your profit.
  • Personal deductible super contributions and losses carried forward are not modelled here.
