Small Business Home Office Deductions in Australia

What Counts as Home-Based Business Claims?

A home-based business is when part of your home is set aside and used mainly for running your business. There are three main deductible home costs:

You can only claim the portion that relates to your business use.

Home Office Running Expenses

These are the everyday costs of keeping your home workspace comfortable and functional. 

Tax tip: You can claim running expenses even if you don’t have a dedicated business area.

Home Office Occupancy Expenses

These cover costs for owning or renting your home, such as mortgage interest, rent, council rates, land tax and home insurance.

You can only claim occupancy expenses if part of your home has the “character of a place of business”, meaning:

Tax tip: If your home does not meet these criteria, you can still claim running expenses but occupancy expenses are not deductible.

Tax warning: There may be other tax implications when you claim occupancy expenses. 

Capital Gain Tax (CGT)

Claiming occupancy expenses can affect your CGT when selling your home. You may lose part of your main residence exemption for the business use portion. CGT concessions may apply, but the rules are complex – professional advice is recommended. More information is available  on the ATO website.

Personal Services Income (PSI) rules

If your business generates PSI, you may not be able to claim occupancy expenses. More information is available on the ATO website.

Motor Vehicle Expenses

If you travel for business from home, you can claim motor vehicle expenses. Travel examples include: 

The vehicle must be owned, leased or under a hire purchase agreement to claim expenses.

Sole Trader Guide to Home-Based Business Claims

Sole traders can claim all three types of expenses using ATO-approved methods.

Home Office Running Expenses

Sole traders can claim these using any of the following methods:

Fixed rate method
Claim 70 cents per hour worked from home (FY2024–25) for energy, phone, internet and stationery. Depreciation on office equipment is claimed separately. Keep a record of hours worked.

Floor area method
If you have a dedicated room, calculate the business portion by dividing the area used for business by the total home area, and apply that percentage to relevant costs. This method is often the most appropriate method to work out the business portion of running expenses, such as utilities bills.

Actual cost method
Use actual receipts and bills for additional business expenses, then calculate the business portion based on usage. Requires detailed records.

Tax tip: Not sure which method to use? Try calculating your expenses using each option and pick the one that works best for your situation.

Home Office Occupancy Expenses

You can only claim these if part of your home has the “character of a business place.” Work out the business portion based on the floor area used.

Motor Vehicle Expenses

How you claim depends on the type of vehicle you use for business travel from home.

Cars
Vehicles like sedans, station wagons and small 4WDs (under 1 tonne and fewer than 9 passengers) can be claimed using:

Cents per kilometre method

Claim up to 5,000 business km per year at 88 cents/km (FY2024–25 and 2025–26). No logbook required, but keep a reasonable record of trips.

Logbook method

Keep a 12-week logbook to calculate the business use percentage of all car expenses, including fuel, servicing, insurance, registration and depreciation.

Other Vehicles
Vehicles like utility trucks, panel vans, minivans, buses or motorcycles (1 tonne or more, or 9+ passengers) must use the actual cost method. Total all vehicle expenses and apply the business use percentage based on a logbook or accurate records.

You can choose one method per vehicle per year and keep clear records to support your claims. 

Tax tip: Looking for a logbook template? The ATO’s myDeductions app helps you keep a digital logbook in multiple ways. You can start a GPS-tracked trip (great for real-time business travel), enter point-to-point trips or record odometer readings.

Company Guide to Home-Based Business Claims

Home Office Expenses

If your business is run as a company, claiming home office expenses works differently. 

The company must have a genuine, market-rate rental agreement with the property owner (even if that’s you).

For more guidance on claiming home office expenses as a company, visit the ATO website.

Tax warning: If there’s no rental agreement and the company reimburses home office expenses to you as an employee, you cannot claim them personally. The company may also need to pay Fringe Benefits Tax (FBT). More information is available on the ATO website.

Motor Vehicle Expenses

You must use the actual costs method to work out motor vehicle expenses, regardless of the type of motor vehicle. Add up all vehicle expenses and apply the business use percentage from a logbook or accurate records.
