If part of your home is completely set aside for business use, you can use the checklist below.

If it is not completely set aside, you also need to consider the amount of time that part of your home is used for income-earning activities.

If you are registered for GST, the business expenses you claim will not include GST, when this applies. If you are not registered for GST, these expenses will include GST.

If you have a mortgage you can claim the same proportion of your mortgage interest (but not the principal) paid during the year. There is no GST involved in this.

For GST, you can claim a portion or percentage of the GST on the expenses.

Like you do for any other business expenses you are claiming, you need to keep invoices and other records for these expenses.
