  • First, determine the proportion of the individual’s basic income tax liability in relation to his small business income. (net small business income ÷ taxable income)
  • Calculate the tax payable in total net business income. (Proportion x tax liability)
  • Calculate small business tax offset (16% x tax payable in total net business income)


Arnold is a sole trader. In the income year 2021/22, Arnold’s taxable income was $80,000 and his net small business income was $30,000. His basic income tax liability was $20,000. What is his small business tax offset?


  • Determine the proportion of Arnold’s basic tax liability in relation to his business.

         ($30,000/$80,000 = 0.375)

         This means that 0.375 of Arnold’s taxable income relates to his small business.     

  • Calculate the tax payable in total small business income.

         (0.375 x $20,000 = $7,500)

         $7,500 of Arnold’s basic income tax liability comes from his net business income.  

  • Calculate Arnold’s business tax offset.

          (0.16 x $7,500 = $1,200)

Arnold’s sole trader gross business offset is equal to $1,200. However, the small business tax offset is capped at $1,000. Therefore, Arnold's sole trader net small business tax offset is $1,000 for the year 2021/22.
