The Simplified Tax System (STS) is an alternative method of determining taxable income for eligible taxpayers. It began on 1 July 2001.
You are eligible to be an STS taxpayer for an income year if:
- you carry on a business in that year
- you have an STS average turnover of less than $1 million in that year (the STS average turnover includes the turnover of any entities you are 'grouped with'), and
- you, together with any entities you are 'grouped with', have depreciating assets with a total adjustable value of less than $3 million at the end of the year.
The STS contains its own simplified capital allowance rules. If you are an eligible taxpayer and elect to enter the STS, you will generally calculate deductions for your depreciating assets using these rules.
In general, most:
- depreciating assets costing less than $1,000 each can be written off immediately
- other depreciating assets with an effective life of less than 25 years are pooled in a general STS pool and deducted at the rate of 30%
- depreciating assets with an effective life of 25 years or more are pooled in a long life STS pool and deducted at the rate of 5%
- newly acquired assets are deducted at either 15% or 2.5% in the first year, regardless of when they were acquired during the year.
More information on working out deductions for depreciating assets under the STS rules is provided in the publication The Simplified Tax System-A guide for tax agents and small businesses (NAT 6459-6.2002).
