Reasons for decision

Summary

As you carry on a business and your aggregated turnover is less than $10 million, you are entitled to apply the simplified depreciation rules by claiming an immediate deduction for a depreciating asset that cost less than $20,000.

However, your depreciation deduction is limited to the percentage your asset is used for business. This means you must only claim a deduction for the portion of the asset used for business purposes, not for the portion for private use. You must make a reasonable estimate on business and private use.

Detailed reasoning

Under sub division 328-D Income Tax Assessment Act 1997 you can choose to use simplified depreciation rules if you have a small business with an aggregated turnover of less than $10 million.

Under these simpler rules, you:

The deduction is limited to the taxable purpose proportion of the asset’s cost.

In your case, you are a small business entity and entitled to a deduction for the business use of the solar system. That is the deductable amount is the portion that relates to the use of the system for the purpose of producing assessable income. As there is a substantial private use purpose, the deduction is reduced accordingly.

The solar system was purchased in June 201X and installed in July 201X. As the solar system was not installed and ready for used in the 201A – 201X financial year, no deduction is allowed for that year. The allowable taxable purpose portion is deductable in the 201X – 201B financial year.
