Participation in STS was optional.

Features of the STS are:

• Cash accounting rather than accruals accounting:
  • Most business income and deductions will be recognised only when they are received and paid.
• A simplified depreciation system (capital allowances): 
  •  Depreciating assets that cost less than $1000 each will be written off immediately and claimed as a deduction in the year in which you started to use the asset, or installed it ready for use, for a taxable purpose.
  • Other depreciating assets which have an effective life of less than 25 years will be pooled and depreciated at the diminishing value rate of 30%.
  • Depreciating assets with an effective life of 25 years or more will be pooled and depreciated at the diminishing value rate of 5%.
• A simplified treatment of trading stock:
  • Taxpayers will only be required to account for changes in their trading stock on hand or do stocktakes at the end of the year where the difference between the value of opening stock and your reasonable estimate of closing stock exceeds $5000.

To be eligible for the STS in an income year you must satisfy the following three tests:

• Be carrying on a business in that year; and
• Have an STS average turnover for that year of less than $1m; and
• The total of the adjustable values of the depreciating assets held by you and your grouped entities at the end of that year must be less than $3m.
