You may like to refer to our notes on claiming working from home expenses here.
The Cents-per-Hour method requires evidence for all hours worked from home; we will ask for a summary in the next question, but please ensure you have diary or timesheet or log-on evidence that you retain for 5 years.
Download or copy your record of hours now in case your employment and/or system changes before the record-keeping minimum is up!
You will also need to keep one receipt from each expense - one phone bill, one electricity bill, one stationery receipt, etc -- save those now to the same safe place.
The Actual Costs method needs only a typical 4-week diary, but it needs to show personal and work related use and needs to be accompanied by ALL the receipts. It gets complicated when claiming for electricity as you need to know the hours used AND power draw for each appliance you run in your home office area - kilowatt hours or watts per hour depend on the item and model. If you have this information handy, please send it through and we'll be happy to calculate your claim on this basis.
