Yes, you can absolutely claim tax deductions for your home office—but the amount you can claim depends entirely on one critical factor: whether you are an employee or operating your own business from home.
It is one of the most common questions our tax experts encounter, especially since working from home became standard practice for many Australians. The rules set by the Australian Taxation Office (ATO) are highly specific, and misunderstanding them can mean missing out on significant savings or, worse, attracting an audit.
Who Can Claim Home Office Deductions
Before tallying receipts, the first crucial step is to determine your employment category. Are you an employee working remotely, or are you a sole trader whose business is based out of your home? This distinction governs the types of tax deductions for your home office you are eligible to claim.
Think of it as two distinct pathways. One is for employees, and the other is for business owners. While both allow claims for the everyday costs of working from your house, only the business owner’s path unlocks deductions for a portion of your largest household bills, such as rent or mortgage interest. Let’s break down what this means for you with some practical examples.
Employees Working From Home
If you are an employee logging on from your kitchen table or a dedicated study, you can claim what the ATO defines as running expenses. These are the additional costs incurred directly because you are performing your job from home instead of the company office.
Common running expenses you can claim include:
- The work-related portion of electricity and gas for heating, cooling, and lighting your workspace.
- The decline in value (depreciation) of home office equipment, such as an ergonomic chair, desk, or computer.
- A percentage of your internet and phone bills directly related to work duties.
- Stationery, printer ink, and other essential computer consumables.
Here is the critical limitation: as an employee, you generally cannot claim occupancy expenses. This is a significant point of difference. It means costs like your rent, mortgage interest, council rates, and home insurance are off-limits. The ATO views these as private costs you would incur regardless of your work location.
Sole Traders and Business Owners
If you are a sole trader, freelancer, or run your own business, the rules change—provided your home is your principal place of business. You can claim all the same running expenses as an employee, but you also gain access to a much larger category of deductions.
The key advantage for business owners is the ability to also claim occupancy expenses. This includes a work-related portion of your rent, mortgage interest, land taxes, council rates, and home insurance premiums.
This distinction is massive. For a home-based business, deducting a percentage of your rent or mortgage interest can result in thousands of dollars in deductions over the 2024-25 tax year. It’s a significant tax advantage unavailable to employees, a policy the ATO clarifies in rulings like TR 93/30.
To qualify, you must genuinely operate a business from home. If you are unsure whether your setup meets the “principal place of business” test, it is always best to seek professional advice. You can also review the ATO’s guidance on home office expenses for their official position.

Choosing Your Calculation Method
Once you have established your eligibility to claim a home office deduction, the next question is: how do you calculate it? This is where you must make a strategic choice. The Australian Taxation Office (ATO) provides two distinct paths: the Fixed Rate Method and the Actual Cost Method.
Your selection will significantly impact how much you can claim and, just as importantly, the records you must maintain. Think of it as choosing between a convenient, all-inclusive package and meticulously selecting items from an à la carte menu. The first option is simple, but the second may yield a larger tax saving if you are prepared to do the administrative work.
The Simple Path: The Fixed Rate Method
The Fixed Rate Method is the streamlined, “set and forget” choice, perfect for those who wish to minimise paperwork. Instead of analysing every utility bill, you simply claim a set rate for every hour you work from home.
This single hourly rate covers several common running expenses in one figure, including the work-related portion of your:
- Electricity and gas for heating, cooling, and lighting.
- Home and mobile phone usage.
- Internet expenses.
- Stationery and computer consumables, like printer ink and paper.
The primary benefit is that you do not need to keep receipts for any of these specific items. Your only obligation is to maintain a record of the hours you worked from home—a simple timesheet, diary, or spreadsheet for the entire financial year is sufficient. However, this rate does not cover the depreciation (decline in value) of office furniture or high-value technology like a laptop, which must be claimed separately.
The Detailed Approach: The Actual Cost Method
For diligent record-keepers aiming to claim every last cent, the Actual Cost Method is the superior choice. This approach requires you to calculate the exact work-related portion of each individual home office expense.
With this method, you claim the actual costs for all your running expenses. This involves a forensic review of your bills—calculating the work percentage of electricity, phone, and internet, plus tallying every dollar spent on supplies. For shared household costs like power, you need a fair and reasonable basis for apportionment, such as using the floor area of your dedicated office as a percentage of your home’s total size.
The Actual Cost Method requires more effort but often leads to a larger deduction if your running costs are high or you have a large, dedicated office space. It is also the only method for eligible business owners to claim occupancy expenses like mortgage interest or rent.
The trade-off for a potentially larger refund is a significantly heavier administrative load. You must retain every receipt and have clear calculations showing precisely how you determined the business portion of each expense.
The image below provides a quick visual snapshot of how the two methods compare.
As you can see, the choice boils down to a simple rate versus a detailed calculation of all your actual home running costs.
Fixed Rate Method vs Actual Cost Method Comparison
Choosing between the two methods can be challenging. To help you decide which one suits your situation and record-keeping style, here is a side-by-side breakdown of the key differences.
| Feature | Fixed Rate Method | Actual Cost Method |
|---|---|---|
| Simplicity | High – very straightforward. | Low – requires detailed calculations. |
| Record Keeping | Minimal – only a log of work-from-home hours is required. | Extensive – must keep all receipts and calculations. |
| Claimable Expenses | Covers a bundle of running costs at a set hourly rate. | Claim the actual work portion of all running costs. |
| Depreciation | Claimed separately for equipment and furniture. | Claimed separately for equipment and furniture. |
| Potential Deduction | Often lower, but convenient. | Can be higher if you have significant expenses. |
| Occupancy Expenses | Not claimable with this method. | Can be claimed by eligible business owners. |
This table makes it clear: if you value ease and have minimal paperwork, the fixed rate is your friend. But if you’re prepared to track everything, the actual cost method could put more money back in your pocket.
Putting It Into Practice: A Practical Example
Let’s see how this plays out with a real-world example. Meet Chloe, a freelance graphic designer who worked 1,500 hours from her home office this financial year.
Using the Fixed Rate Method: The ATO’s rate is 67 cents per hour for the 2023-24 financial year. Chloe’s calculation is simple: 1,500 hours x $0.67/hour = $1,005. She can claim this amount for her running costs without a single bill, plus a separate claim for the depreciation of her computer.
Using the Actual Cost Method: Chloe determines her dedicated home office occupies 15% of her home’s total floor space. Her annual bills are: electricity ($2,000), gas ($1,000), and internet ($1,200). Her work-related portion is 15% of $4,200, which is $630. Additionally, she spent $300 on stationery and has a work-only mobile plan costing $480 a year. Her total claim is: $630 + $300 + $480 = $1,410, plus her computer depreciation.
In Chloe’s case, investing the time to use the Actual Cost Method results in a substantially higher claim. However, this was only possible because she kept meticulous records and performed the calculations. For a deeper dive into the fixed rate, you can explore further insights on home office deductions.
The smart move is to run the numbers for both methods before lodging your tax return. It’s the only way to ensure you are not leaving money on the table.

Your Complete Home Office Expense Checklist
Knowing you can claim home office expenses is one thing, but knowing exactly what the ATO allows you to claim is another. To ensure you are not leaving money on the table, it pays to be organised.
Think of your expenses as falling into three main categories: daily Running Expenses, larger Capital Expenses, and—for some business owners—the significant Occupancy Expenses. Let’s break down what belongs in each.
Running Expenses: The Day-to-Day Costs
Running expenses are the ongoing costs that keep your home office operational. These are the consumables and services you use while working. If you use the Actual Cost Method, you must be precise when calculating the work-related portion of these bills.
Here’s what to look for on your statements:
- Electricity and Gas: This covers power for lighting, heating, and cooling while you work. You must calculate the work portion of the household bill, typically based on your office’s floor area.
- Phone and Internet Bills: It is crucial to determine the percentage of your phone and internet usage that is strictly for work. Practical Example: Keep a detailed log for a typical four-week period to establish a defensible work-use percentage. If 40% of your data usage over that month was for work, you can apply that 40% to your annual internet bill.
- Stationery and Supplies: This includes printer paper, ink, pens, notebooks, and postage. If these items are used 100% for work, they are generally fully deductible.
- Cleaning Costs: If you hire a cleaner, you can claim the portion of their fee that relates to cleaning your dedicated home office space.
One of the most common mistakes is claiming 100% of a shared utility bill. The ATO requires a fair and reasonable calculation; getting this wrong is an immediate red flag.
Capital Expenses: The Big-Ticket Items
Capital expenses, or what the ATO calls depreciating assets, are significant items purchased for your office with a longer lifespan. You cannot claim the full cost upfront. Instead, you claim its decline in value over time, known as depreciation.
This is where many people miss out on substantial deductions. Your checklist should include:
- Office Furniture: This includes your desk, ergonomic chair, filing cabinets, and bookshelves. There are significant benefits of height-adjustable desks that make them a smart investment for your health and tax return.
- Technology and Equipment: This category includes your computer, laptop, printer, scanner, and a dedicated work mobile phone.
- Software: Any professional software required for your job, whether a subscription or a one-off purchase, can be claimed here.
For items costing $300 or less, you can typically claim an immediate deduction for the full business-use portion. Anything over $300 must be depreciated over its effective life, as per ATO guidelines.
Occupancy Expenses: A Game-Changer for Business Owners
This final category is typically reserved for sole traders or business owners whose home is their principal place of business. These are the high-value costs related to owning or renting your property. For those who qualify, the deductions can be massive.
Practical Example:
Sarah is a freelance consultant, and her home office occupies 20% of her house’s total floor area. It is her only place of business.
Her annual occupancy costs are:
- Mortgage Interest: $22,000
- Council Rates: $2,000
- Home Insurance: $1,500
Sarah can claim 20% of these total costs. Her occupancy expense claim is $5,100 (20% of $25,500). This is a powerful deduction that employees cannot access. The logic is similar to managing an investment property, which you can read more about in our guide to https://www.endurego.com.au/a-guide-to-maximizing-your-rental-property-tax-deductions.
Being methodical and separating costs into these categories gives you the confidence to claim everything you are entitled to.

Getting Your Paperwork Right for the ATO
Claiming tax deductions for your home office is a brilliant way to lower your taxable income, but any deduction is only as strong as the evidence you have to support it. Think of your records as your best defence if the Australian Taxation Office (ATO) ever scrutinises your return.
Maintaining good records is not just a suggestion; it is a mandatory rule that separates a successful claim from a disallowed one. The required records depend entirely on your chosen calculation method.
Records for the Fixed Rate Method
If you opt for the simplicity of the Fixed Rate Method, your primary record-keeping task is straightforward but must be done correctly. You must keep a running log of the total number of hours you worked from home during the financial year.
This log does not need to be complex, but it must be accurate and kept contemporaneously (as you go). You cannot estimate a number at the end of the year.
Your proof can take several forms:
- A simple diary or calendar: Jot down your start and finish times each day you work from home.
- A dedicated spreadsheet: Create a log with columns for the date, hours worked, and a running total.
- Timesheets: If your employer requires them, they are the perfect record of your hours.
The ATO is explicit on this: “You must have a record of the total number of hours you work from home for the entire income year.” This is a strict requirement, making your logbook the single most important piece of evidence for this method.
Remember, while this method saves you from collecting utility bills, you still need receipts for any capital items claimed separately, like office furniture or a new laptop costing over $300.
Documentation for the Actual Cost Method
Choosing the Actual Cost Method demands far more organised paperwork. Because you are calculating the exact work-related portion of each expense, you need a clear paper trail for every dollar claimed.
Your record-keeping system should include:
- Receipts and Invoices: Retain every receipt for office purchases, such as stationery, printer ink, and software subscriptions.
- Utility Bills: Keep a complete file of your electricity, gas, internet, and phone bills for the entire year.
- Depreciation Schedule: For assets over $300, track their purchase date, cost, and how their value declines each year.
- Your Apportionment Calculations: You must have a clear, logical basis for how you calculated the work-related percentage of shared costs. This typically involves measuring your home office floor area against your home’s total area.
Practical Example:
Your home office is 10 square metres, and your entire home is 100 square metres. Your work-use percentage for shared running costs (like your power bill) is 10%. If your quarterly electricity bill is $500, you must keep the bill and a record showing your calculation: $500 x 10% = $50 claimable for that quarter.
It is not just about hoarding receipts; it is about having a system. For strategies on organizing your important tax documents, it’s wise to read up on creating an audit-proof system. Consistency is your best friend.

Common Mistakes to Avoid When Claiming
Maximising your home office tax deductions is a fantastic way to boost your tax refund, but navigating Australian Taxation Office (ATO) rules can be challenging. A few common mistakes can quickly turn a valid claim into a rejected one—or worse, trigger an audit.
Let’s walk through the common pitfalls so you can ensure your tax return is both maximised and fully compliant.
Overlooking the Personal Use Portion
This is one of the most frequent errors: claiming 100% of a bill that is also used for personal life. The ATO is clear: you can only claim the work-related portion of any shared expense.
Practical Example: Your family streams movies on the same Wi-Fi you use for work video calls. Claiming the entire internet bill is a major red flag for the ATO and is incorrect. The correct method is to determine a fair percentage for work use. Keeping a log over a representative four-week period is the gold standard for evidence.
Confusing Running and Occupancy Expenses
Another critical mistake, especially for employees, is incorrectly claiming occupancy expenses. These are costs related to owning or renting your property, such as rent, mortgage interest, council rates, and home insurance.
Unless you are a sole trader running your business from home (and it’s your principal place of business), you cannot claim these costs. For employees, the ATO views these as private living expenses. Stick to claiming your running expenses and depreciation on office assets.
Neglecting Your Record-Keeping Duties
A deduction is worthless without proof. Guessing your hours or estimating costs without records is a recipe for disaster.
For the Fixed Rate Method, the ATO requires a complete, contemporaneous record of the hours you worked from home. Without that logbook, your entire claim can be disallowed. For the Actual Cost Method, no receipts for expenses means your claim is invalid. Being organised is one of the best ways to understand how to avoid an ATO tax audit.
Not Claiming Depreciation on Assets
Many people miss this. For any item costing more than $300, you generally need to claim its decline in value—or depreciation—over several years. Forgetting to claim depreciation means you are leaving money on the table. Each year, you can claim a portion of the asset’s cost as a deduction, reducing your taxable income over the item’s effective life.
Navigating these rules can be tricky. Here’s a quick summary of what is generally claimable versus non-claimable.
Claimable vs. Non-Claimable Home Office Expenses
| Expense Item | Generally Claimable? | Important Conditions |
|---|---|---|
| Home Office Furniture | Yes (Depreciation) | For items >$300, claim depreciation. For items <$300, claim immediate deduction. |
| Computers & Laptops | Yes (Depreciation & Running Costs) | Depreciate the asset cost; claim running costs like internet and power based on work use. |
| Internet & Phone Bills | Yes (Work-related portion only) | Must have records (e.g., a 4-week diary) to prove the work-use percentage. |
| Rent or Mortgage Interest | No (for employees) | These are “occupancy expenses” and not deductible for employees working from home. |
| Council Rates & Insurance | No (for employees) | Also considered private occupancy expenses unless you run a business from home. |
| Tea, Coffee & Milk | No | The ATO considers these private expenses, even if your employer provides them at the office. |
| Stationery & Printer Ink | Yes (Work-related portion) | Keep receipts and only claim the portion used for your job. |
This table is a great starting point, but every situation is unique.
Your Questions on Home Office Deductions Answered
Even with a detailed guide, specific questions often arise at tax time. Let’s tackle some of the most common queries to give you final clarity.
Can I Claim Deductions If I Only Work From Home Part-Time?
Absolutely. You do not need to work from home full-time to claim home office expenses. What matters is that you genuinely incur extra running costs because you perform your job duties from home. Your claim must align with the time you actually spend working from home.
Practical Example:
You work from home two days a week for 16 hours. Over 48 weeks of the year, your total hours are 768. That is the number you would use in your calculation for the Fixed Rate Method. It’s that simple.
Do I Need a Separate Room to Claim a Home Office?
This is a common misconception. You do not need a separate, dedicated room to be eligible for home office deductions. The ATO understands many people work from a dining table or a nook in a shared space.
However, your workspace affects what you can claim and how you calculate it.
- Shared Spaces: You can still claim running costs. The Fixed Rate Method is often the easiest path here.
- Dedicated Room: If you have a separate room used exclusively for work, the Actual Cost Method may yield a higher deduction, as you can calculate utility costs based on the room’s floor area.
The ATO’s guidance, such as in Taxation Ruling TR 93/30, focuses on whether you incurred deductible expenses. The setup itself simply guides your calculation method.
Can I Claim Travel from Home to My Main Workplace?
This is a firm “no” from the ATO. The trip between your home and your regular workplace is almost always considered private travel and is not deductible. This rule applies even if you check emails at home before commuting. The exceptions are extremely rare.
What Happens If My Employer Reimburses Me for Expenses?
You cannot double-dip. If your employer reimburses you for a specific cost, you cannot also claim that amount as a deduction. You can only claim deductions for work expenses you paid for with your own money and were not reimbursed for. If an allowance only covers part of a bill, you may be able to claim the work-related portion you personally covered.
Is My Morning Coffee or Lunch a Claimable Expense?
Unfortunately, no. The ATO considers food, drinks, and other sustenance to be private expenses. It does not matter if your employer would normally provide these in the office. These are not costs incurred to earn your income and do not qualify as a legitimate tax deduction for a home office.
