Home Office Expenses
As a general rule, expenses associated with a taxpayer's home are of a private or domestic nature and do not qualify as deductions for taxation purposes. However, if you do work relating to your business at home, you may be able to claim a deduction for some of the expenses relating to the area you use for business purposes.
The expenses you may be able to claim can be divided into two broad categories:
• occupancy expenses, and
• running expenses.
Occupancy expenses are expenses related to your ownership, rental or use of the home and are not affected by your income earning activities. They include rent, mortgage interest, land and water rates, and housing insurance premiums.
Running expenses are expenses related to using facilities within your home, for example, electricity charges for heating, cooling and lighting, cleaning costs, depreciation, leasing charges and the cost of repairs to items of furniture and furnishings in the office. Running a business from home means that these expenses may be higher than if you weren’t running a business from home.
What expenses can you claim?
Whether you can claim both running expenses and occupancy expenses depends on the nature of your home work area. Basically there are three ways you can operate from home:
• home is your principal place of business and you have an area set aside exclusively for business activities;
• home is not your principal place of business but you have a home work area set aside exclusively for business activities, or
• you work at home but it is not your principal place of business and you don’t have an area set aside exclusively for business activities. For example, you work when others are not present in a living area or garage.
Expenses you may be able to Claim from working at home:
Home is principal place of business and you have a work area
Home is not principal place of business but you have home work area
You work at home but don’t have home work area

Principal Place of Business
Where you have an area of your home set aside exclusively for business activities, it has to have the character of ‘a place of business’. While this will depend on your particular circumstances, an area of your home is likely to have the character of a place of business if it is:
• clearly identifiable as a place of business (for example, you have a sign identifying your business at the front of your house);
• unsuitable to be used for private purposes in association with the home (for example, it’s not a suitable place for someone to sleep in);
• used almost exclusively for carrying on a business, or;
• regularly visited by clients.
Tax consequences of using your home as your principal place of business
You generally don’t have to pay capital gains tax on any capital gain you make on the sale of your main residence (home). However, where you use your home as a place of business and are entitled to a tax deduction for some of your mortgage interest, or would be entitled to a deduction if you had a mortgage, you do have to pay capital gains tax if you make a capital gain on the sale of your home.
The amount of capital gains tax relates to the proportion of your home used for business.
How much to claim
You must apportion expenses between business and private use to work out how much you can claim. A common method of working out how much to claim is the floor area (as a proportion of the floor area of your whole home). If the business percentage is based on anything other than the floor area (for example, on actual electricity use) you will need to clearly document your claim to show how you arrived at the amount.
Where you do some work at home but home is not your principal place of business and you don’t have an area of your home set aside exclusively for business, you can’t claim on a floor area basis as this area is also used for non-business purposes.
Substantiation Rules
If you claim a deduction for expenses related to a home work area, you must be able to prove that you incurred the expenses. To ease compliance costs for individuals, the Tax Office accepts the following:
• You can keep a diary for a representative four-week period each financial year to establish a pattern of use for your home work area for the entire year. Where there is no regular pattern to how you use your home work area, you’ll need to keep records of each time you use the area during the year, and the purpose for which you use it.
• Instead of recording actual expenses for heating, cooling, lighting and depreciation of furniture (desks, tables, chairs, cabinets and shelves), you can claim a deduction of 34 cents an hour based on actual use or an established pattern of use.
