For many Australian business owners, the home office has become the new headquarters. But are you maximising your tax savings and staying compliant with the latest home office deduction rules in Australia?

Getting your home office deductions right has never been more critical. The Australian Taxation Office (ATO) has updated its guidance, and many business owners are inadvertently claiming incorrectly, putting them at risk of an audit. This guide cuts through the noise, showing you how to claim with confidence and avoid costly mistakes. We’ll also cover the non-negotiable record-keeping you need to have in place to make your claims audit-proof.

Key Takeaways for 2026

• Fixed Rate Method: The ATO’s simplified fixed rate is 67 cents per hour. It covers your electricity, gas, internet, phone, and stationery costs. You must keep a log of all hours worked for the entire year.
• Actual Cost Method: This method allows you to claim the business-use portion of your actual expenses. It requires detailed records but can result in a larger deduction.
• Record-Keeping is Critical: The ATO now requires a full-year log of hours worked for the fixed rate method estimates are no longer accepted. For the actual cost method, you need all receipts and a clear calculation of your business-use percentage.
• Occupancy vs. Running Costs: Most business owners can claim running expenses. Claiming occupancy costs like rent or mortgage interest is complex and has significant Capital Gains Tax (CGT) implications.
• Avoid Double-Dipping: A common mistake is using the 67-cent rate and then separately claiming an internet or phone bill. This is not allowed and is a red flag for the ATO.

Who Can Claim Home Office Expenses?

If you are a business owner, sole trader, or freelancer who works from home, you are generally eligible to claim deductions for the costs you incur. This applies whether you work from home occasionally or your home is your principal place of business.

The key condition set by the ATO is that the expenses must be directly related to earning your assessable income. You must also have spent the money yourself and have a record to prove it.

ATO Fixed Rate Method Explained: The 67 Cents Per Hour Rule

Imagine a straightforward way to claim your day-to-day running costs without needing a shoebox full of receipts for every little thing. That’s the thinking behind the ATO’s revised fixed rate method. It’s a simple, ‘all-in-one’ approach designed to make ATO work from home deductions for 2026 easier.

How the 67 Cents Per Hour Rate Works

For every hour you work from home, the ATO lets you claim a flat rate of 67 cents. This single figure is designed to bundle up the most common running expenses you incur.

So, what exactly is covered in this fixed rate method 67 cents Australia? According to the official ATO guidance, the rate covers:

• Energy Costs: The additional electricity and gas used to power your lights, heating, cooling, and electronic equipment.
• Internet and Phone: The work-related portion of your home internet and mobile phone bills.
• Stationery and Consumables: All those small but necessary items like paper, pens, printer ink, and toner cartridges.

Crucial Rule: If you use the 67 cent fixed rate, you cannot make a separate claim for any of the expenses listed above. For example, you can’t claim 67 cents per hour and also claim a percentage of your monthly internet bill. This is a common mistake that can easily trigger an ATO audit. However, you can still make separate claims for the depreciation of equipment like computers and office furniture.

Record-Keeping Is Non-Negotiable

While the fixed rate method cuts down on calculations, it absolutely does not get you out of keeping records. The ATO’s requirements here are stricter than ever.

You must keep a contemporaneous record of all hours worked from home for the entire financial year. A four-week sample or a rough estimate won’t cut it anymore. This can be a diary, a digital logbook, or a simple timesheet. You must also keep evidence, such as one quarterly bill, proving you incurred each of the running expenses covered by the rate (e.g., one electricity bill, one phone bill).

Actual Cost Method Explained: For Potentially Larger Deductions

If the fixed-rate method feels too simplistic, the actual cost method home office approach might be where you find the real value. Think of it as the detailed, itemised approach to your tax deductions.

This method is ideal for business owners with a dedicated home office and significant expenses. It requires more paperwork, but the payoff can be a much larger tax deduction.

Calculating Your Business Use Percentage

The whole system hinges on one key figure: your business use percentage home office. This is the number you’ll apply to shared household bills like electricity and internet to work out the deductible amount. The ATO accepts two main ways to calculate this:

• Floor Area Basis: Ideal for a dedicated office. You measure the total square metres of your home and the square metres of your office. If your office takes up 10% of your home’s total floor area, you can generally claim 10% of your shared utility costs.
• Actual Usage Basis: For mixed-use items like your phone and internet, you must demonstrate your work-related portion. This usually means keeping a diary for a representative four-week period to establish a reasonable percentage for claiming electricity and internet on tax in Australia.

Important: While it demands more discipline, the actual cost method is often the best choice for businesses with high running costs. But getting the calculations wrong can lead to ATO headaches. This is where professional tax planning becomes a non-negotiable.

What Expenses Can You Claim? Fixed Rate vs. Actual Cost

So, fixed rate or actual cost? The right choice is a trade-off between simplicity and a potentially larger deduction. To help you decide, let’s break down exactly what you can claim with each method.

Expense Type	Fixed Rate Method (67¢/hour)	Actual Cost Method
Electricity & Gas	Included in the 67¢ rate. You cannot claim this separately.	Claim the work-related portion of your actual bill.
Internet & Phone	Included in the 67¢ rate. You cannot claim this separately.	Claim the work-related portion based on your actual usage records.
Stationery & Consumables	Included in the 67¢ rate. You cannot claim this separately.	Claim the full cost of items used 100% for business.
Equipment & Furniture (Depreciation)	Claimed separately. The fixed rate doesn’t cover the decline in value of your desk or computer. You can claim depreciation on home office equipment in Australia in addition to the hourly rate.	Claimed separately. You claim depreciation on assets like desks, chairs, and computers based on their business-use percentage.
Rent & Mortgage Interest (Occupancy)	Cannot be claimed. This is a strict rule under the fixed rate method.	Limited and risky. Generally only for those with a dedicated, exclusive workspace. Be aware that CGT will likely apply when you sell your home.

Occupancy vs. Running Expenses: A Crucial Distinction

The key to getting your home office deduction rules in Australia right is knowing the difference between occupancy vs running expenses ATO.

• Running Expenses: These are the costs of using your home office day-to-day, like power, internet, phone, and stationery. Almost any business owner working from home can claim these.
• Occupancy Expenses: These are the costs of owning or renting the property itself, like rent, mortgage interest, council rates, and insurance. These are much harder to claim and often come with Capital Gains Tax (CGT) implications down the line. If you claim a portion of your home as a place of business, the ATO may treat that portion as a commercial asset, meaning you lose the main residence exemption on it when you sell.

How to Calculate Your Home Office Deduction

Let’s turn the rules into a real deduction on your tax return.

1. Choose Your Method: Decide between the simpler fixed rate method or the more detailed actual cost method based on which will deliver a better outcome and what records you have.
2. Calculate Hours Worked: For the fixed rate method, tally up the total hours you worked from home for the entire financial year from your diary or logbook. This is a non-negotiable record keeping for work from home deductions requirement.
3. Gather Expense Records: For the actual cost method, collect all your utility bills, receipts for stationery, and asset purchase invoices. Calculate your business-use percentage based on floor area or a usage diary.
4. Apply the Correct Method:
   • Fixed Rate: Total Hours x $0.67. Add any separate claims for asset depreciation.
   • Actual Cost: Sum up the business-use portion of all your running costs and add claims for asset depreciation.
5. Keep All Documentation: Store your logbook, receipts, and calculations securely for at least five years, as required by the ATO. You must be able to produce these if audited.
6. Include in Tax Return: Enter the final calculated amount in the “other work-related expenses” section of your tax return, ensuring you follow the specific instructions for the method you’ve chosen.

Worked Example: Sole Trader Scenario

Let’s look at Sarah, a sole trader who worked 1,000 hours from her home office this year.

• Fixed Rate Method: 1,000 hours x $0.67/hour = $670 deduction. She can also claim depreciation on her $1,200 office computer separately.
• Actual Cost Method: Sarah’s home office is 10% of her home’s floor area. Her total utility bills (electricity, internet) for the year were $3,500.
  • Running costs: $3,500 x 10% business use = $350.
  • Depreciation on her $1,200 computer (let’s say 25% diminishing value) = $300.
  • Total actual method claim = $350 + $300 = $650.

In this scenario, the fixed rate method provides a slightly better deduction ($670 vs $650) with less administrative effort. However, if Sarah’s utility costs were higher or her business use percentage was greater, the actual cost method might have been more beneficial.

Record-Keeping Requirements to Stay Audit-Proof

When it comes to home office deductions, your paperwork is your only defence in an audit. Getting your documentation right from the start is the only way to claim with confidence.

Common Mistakes to Avoid and How to Fix Them

The ATO is paying closer attention to home office expense tax deductions in Australia. Here are a few common slip-ups and how to fix them.

• Mistake: No record of hours. Using an estimate or a 4-week sample.
  • Fix: Maintain a contemporaneous diary or logbook for the entire financial year. A simple spreadsheet or app is perfect. This is a strict ATO guideline for working from home.
• Mistake: Double claiming internet/phone bills. Using the 67-cent rate and also claiming a portion of your Telstra bill.
  • Fix: Understand that the 67-cent rate is a package deal covering electricity, internet, phone, and stationery. Stick to one method only for these costs.
• Mistake: Claiming private expenses. Claiming 100% of a shared utility bill or personal items.
  • Fix: Apportion correctly. For the actual cost method, you must have a reasonable basis for your business-use percentage, supported by a floor plan or usage diary.

Frequently Asked Questions

Can I claim rent for my home office in Australia?

Claiming rent is considered an “occupancy expense” and is very difficult for most business owners. You can only consider it if you run your business from home and have a dedicated area used exclusively for business. Crucially, claiming rent while working from home in Australia will almost certainly trigger Capital Gains Tax (CGT) when you sell your property. It is highly recommended to seek professional advice from a tax agent before making such a claim.

What is the 67 cent method?

The 67 cent method is the ATO’s revised fixed rate for claiming work-from-home running expenses. For every hour you work from home, you can claim 67 cents. This rate covers your electricity, gas, internet, mobile/home phone, and stationery. You must keep a record of your hours worked.

Do I need receipts for the 67 cent method?

While you don’t need receipts for every small item, you must keep evidence that you incurred the expenses the rate covers. This means keeping at least one quarterly bill for your electricity, internet, or phone as proof. You still need separate receipts for any equipment you depreciate.

Can sole traders claim home office expenses in Australia?

Yes, absolutely. Sole trader home office deductions in Australia follow the same rules. You can choose either the fixed rate (67 cents/hour) or the actual cost method, provided you have the required records to substantiate your claim.

What happens if I get audited?

If the ATO audits your home office claim, they will ask for your records. This includes your log of hours, receipts for any actual costs claimed, and your calculations for any business-use percentages. If you cannot provide adequate records, the ATO can disallow your entire claim and may apply financial penalties.

Can I switch between the fixed rate and actual cost methods each year?

Yes. You can choose whichever method gives you a better deduction each financial year, as long as you have the correct records to support the method you choose for that year. You cannot, however, mix and match methods within the same financial year.
