When working from home I suggest claiming..
Electricity for heating and cooling and depreciation of office furniture – claim at $0.52 per hour. Keep a logbook of the hours worked from home.
Phone and internet – claim a percentage for work related purpose based on estimated actual work related costs.
Stationery – claim based on actual usage. Keep your invoices to substantiate.
Office equipment (EG laptop owned by you not your employer) – claim depreciation based on actual % of work related activities. Invoice required for purchase of laptop.
Give me a call if you need further clarification or would like me to send you the ATO guide.
