If you're working from home, you may be able to claim a tax deduction for additional running expenses, including:
heating and cooling
depreciation of office equipment
Usually people calculate these expenses by claiming a fixed rate of 52 cents per hour or calculating each expense. With more people working from home due to COVID-19, we've temporarily introduced a shortcut method. From 1 March until 30 June 2020, you can claim a rate of 80 cents per work hour for all additional running expenses.
This means that all you need to do is record the hours you worked from home and when you complete your tax return, you can multiply that number with $0.80 to calculate your deduction.
Note that you can't claim a deduction for items provided by your employer or if you have been reimbursed for the expense.
