Temporary Work From Home.

If you’re an employee and temporarily work from home due to recent events, such as COVID-19 (coronavirus), bush fire and drought, you may be able to claim a deduction for expenses you incur relating to that work.
You may be able to claim a deduction for additional running expenses you incur such as heating, cooling, and lighting. You can also claim the work-related proportion of the decline in the value of office equipment.
In most cases, if you work from home as an employee and claim working from home expenses, there are no capital gains tax (CGT) implications for your home.
You must keep records to show these expenses and how you have calculated your claim.
