Working from home has become normal for many Australians. For some, it is a convenience a few days a week. For others, it is where the business runs entirely. Either way, the question comes up every year at tax time.
Can I claim my home office as a business expense?
The short answer is yes, but only in certain ways, and only if you meet specific conditions. The longer answer is where things often go wrong. Many people either claim too much and create risk, or claim too little and miss out on legitimate deductions.
As expert accountants in Port Stephens and Nelson Bay, we spend a lot of time helping clients get this right. This article walks through what you can claim, what you cannot, and how to approach home office deductions safely.
What does the ATO mean by a home office?
The Australian Taxation Office does not treat every spare room the same way. The tax treatment depends on how the space is used and how central it is to your income-earning activities.
Broadly, there are two categories:
- A home office that is used for work but is not a place of business
- A home office that qualifies as a place of business
This distinction is important because it directly affects the types of expenses you are eligible to claim as deductions.
A home office is not a place of business.
This is the most common situation.
If you work from home but your home is not your main place of business, the ATO considers your home office to be a workspace within your home rather than a business premises.
Examples include:
- Employees who work from home part-time
- Business owners who also work on client sites
- Professionals who use a home office for admin and planning
If your home office does not meet the criteria for a place of business, you are typically limited to claiming running expenses. You cannot claim occupancy expenses in this situation.
What are running expenses?
Running expenses are the extra costs you incur when working from home.
These can include:
- Electricity and gas for lighting and equipment
- Internet and phone usage
- Stationery and office supplies
- Depreciation of office furniture and equipment
You can claim the work-related portion of these costs.
There are two main ways to calculate these expenses. The method you choose affects how much you can claim and what records you need.
Fixed rate method
The fixed-rate method allows you to claim a set amount per hour for time spent working from home.
This rate covers items such as electricity, internet, phone use, and stationery. It does not include depreciation of assets like desks or computers, which can be claimed separately.
To use this method, you must keep a record of hours worked from home, such as a diary or timesheet.
This method is simple and suits many people, especially those with straightforward work patterns.
Actual cost method
The actual cost method involves calculating the real work-related portion of your household expenses.
For example, you might calculate:
- The percentage of your electricity used for work
- The portion of the internet used for business
- The work-related use of your phone
This method can yield higher deductions, but it requires detailed records and sound calculations.
Many small business accounting clients in Port Stephens prefer this method when their home office use is substantial and ongoing.
The home office is a place of business.
This is less common and carries more tax implications.
A home office is considered a place of business when it is:
- The main place where you run your business
- Clearly identifiable as a business area
- Used exclusively or almost exclusively for work
- Not easily adaptable for private use
Examples include:
- A consultant with no other office location
- A trades business that operates admin and bookings solely from home
- A professional practice run entirely from a home office
Meeting these conditions may allow you to claim both running expenses and occupancy expenses, unlike a home office that is not a place of business.
What are occupancy expenses?
Occupancy expenses include the costs of owning or renting your home.
They can include:
- Rent
- Mortgage interest
- Council rates
- Building insurance
These expenses are claimed based on the portion of the home used as a place of business.
This is where caution is essential.
Capital gains tax implications
Claiming occupancy expenses can affect your main residence capital gains tax exemption.
If part of your home is treated as a place of business, that portion may lose its full capital gains tax exemption when you sell the property.
This does not automatically make claiming occupancy expenses a bad idea, but it does mean the long-term impact should be considered carefully.
A Nelson Bay tax agent can help model whether the short-term tax benefit outweighs the long-term capital gains exposure.
Common mistakes we see
Home office claims are an area the ATO watches closely. Common errors include:
- Claiming occupancy expenses without meeting the place of business tests
- Claiming private internet or phone use as fully business-related
- Not keeping records of hours worked from home.
- Using outdated rates or methods
- Overclaiming depreciation
These mistakes are often unintentional, but they can still result in adjustments, penalties, or interest charges.
Employees versus business owners
Employees and business owners are treated slightly differently.
Employees can generally claim running expenses if they work from home to earn income. However, they cannot claim occupancy expenses unless their home is a place of business, which is uncommon for employees.
Business owners may be able to claim occupancy expenses if their home qualifies as a place of business, in addition to running expenses.
The structure you operate under matters. Sole traders, partnerships, and companies each have different considerations.
This is where business advisory in Nelson Bay becomes important. Structure and tax outcomes are closely linked.
Record-keeping requirements
Good records protect you.
At a minimum, you should keep:
- A diary of hours worked from home
- Copies of bills for electricity, internet, and phone
- Evidence of how you calculated the business use percentages
- Asset purchase invoices
The ATO expects records to be reasonable and contemporaneous, not recreated at tax time.
Bookkeeping services in Nelson Bay often help business owners keep these records organised throughout the year.
Working from home occasionally
If you only work from home occasionally, your claim will usually be smaller.
That is fine. Deductions should reflect reality.
Trying to force a large claim when your home office use is minor increases risk without much benefit.
The role of your accountant
A good accountant does more than tell you what you can claim.
They help you understand:
- Which method suits your situation
- How to document your claim properly
- Whether claiming occupancy expenses makes sense
- How your home office interacts with other deductions
This is why many people searching for accountants near me are really looking for clarity and confidence, not just tax returns.
