Working from home

The flat-rate working-from-home allowance has been increased to 70 cents per hour for the 2024-2025 financial year. If you choose to claim under this method, you cannot make a separate claim for home office stationery, electricity, internet, mobile and home phone, though you can still claim for equipment such as laptops, printers and furniture.

Your mobile calls alone may be a bigger deduction. It may already be too late to keep the appropriate records to claim the per-hour method. You need a record of hours worked for the whole year, not just a representative sample. Do you have timesheets?

Alternatively, consider claiming these expenses individually by keeping receipts and a diary for one month to show the ratio of work to private use. If you are living with other people, forget about trying to keep a diary for internet use – all their use has to be recorded as well.

Your mobile is easy enough; just screenshot a month of recent calls, print and mark whether private or work. For laptops, printers and furniture, record the hours for private use and for work use over a month.

Electricity can be calculated by turning everything else off in the house except the office and looking at the meter and your bill for the cost per kilowatt-hour.

Car logbook

You need to keep one for three months every five years. Just make sure you start it before the end of the financial year, even if it finishes next financial year.

You will need to keep receipts for all expenses associated with the vehicle, and take the speedo reading every June 30. You can avoid having to keep fuel receipts if you do a fuel test by filling up the vehicle and recording the speedo reading, then the next time you fill up again, record the speedo reading and keep the fuel receipt.

This together with the speedo reading each June 30 will allow you to calculate the cost of fuel for the year.

Kilometre method

You can claim up to 5000 kilometres, at 88 cents a kilometre, per vehicle per owner of the vehicle by using a detailed reasonable estimate. Keep a record of regular travel for work purposes for a month, plus a diary entry for one-off trips over the year.
