About small-Business instant asset write-off

As part of the Government Economic Stimulus Package, it was first introduced in the 2015‑16 Budget, and the threshold was $30,000 and increased earlier this year to $150,000. More recently it has been upped again in response to the Covid-19 recovery plan to an unlimited valuation allowing businesses to immediately fully depreciate eligible asset purchases, including solar power systems. 

Businesses with a turnover of up to $5 billion will be able to immediately deduct the full cost of eligible depreciable assets, like a commercial solar system, acquired from 6 October 2020 and first used or installed by 30 June 2022.

Over time, you may to repair or maintain the performance of solar system, while new solar and energy efficient equipment is included as well as improvements to existing equipment and infrastructure, such as upgrading an existing solar system.

If you have purchased or are planning to purchase a solar system for your business, you may be eligible to claim an immediate deduction.
The following tips can help you get your instant asset write-off claim right:

  • Check if you are an eligible business on the ATO website 
  • The solar system must be first used or installed ready for use before 30 June 2022.
  • If your solar system is for a mix of business and private use, you can only claim the business portion
  • If you do not use the simplified depreciation rules, you may be eligible to deduct an amount using accelerated depreciation for your solar system.
How long does a solar system installation take?

Installation will depend on the size of the solar power system and the roof condition, but typically takes 1 to 2 days for a 6kW system.

Which system is right for me?

Going off grid can be a big undertaking but one that is made easier by choosing the right off grid system. There are plenty options out there for off-grid batteries, power and storage. The right system for you will depend on your energy status, your location and what you want to achieve from solar battery storage and energy supply. Ensuring your system matches your power needs and uses high quality components can mean the difference between a long lasting energy source and a lot of unwanted maintenance.
