Can I Claim Home Office Expenses in Australia? (2026)

Who this page is for: Employees and small business owners trying to work out what home office costs may be deductible.

Last reviewed: 27 April 2026

Direct answer

You may be able to claim home office expenses in Australia if you incur extra costs from working at home and keep the right records, but the right method matters. For most employees, the main choice is whether the fixed rate method or actual cost method fits better, and most people should be careful not to treat rent, mortgage or other occupancy costs as a standard employee claim.

What most people need to sort out first

Whether you are claiming as an employee or as someone running a business from home.
Whether the fixed rate method or actual cost method actually applies to your situation.
Whether phone, internet or energy costs are already covered by the method you are using.
Whether you have records of hours worked from home and the costs claimed.

Home-based business claims can be wider than normal employee work-from-home claims, which is why the first step is identifying which rules actually fit your setup.

Short explanation

For many employees, the main decision is whether the fixed rate or actual cost method fits better. The fixed rate method includes certain running costs like internet, phone, energy and stationery, while the actual cost method requires you to work out the actual additional expense you incurred.

Running a business from home is a different question again, because the home-based business rules can be wider than the normal employee position. That is why this page should be read as a starting point, not as a blanket permission to claim every household bill.

Key rules

Choose the method that actually applies to your situation before working out the claim.
Do not separately claim expenses already covered by the fixed rate method.
Keep records of hours worked from home and the costs you are claiming.
Home-based business rules can differ from normal employee working-from-home rules.
Occupancy costs such as rent or mortgage interest are not a standard employee claim.

Common mistakes

Double counting phone or internet costs on top of the fixed rate method.
Assuming every person who works from home can claim rent or mortgage costs.
Using a rough estimate without keeping any record of hours or bills.
Mixing up employee work-from-home rules with home-based business rules.

Frequently asked questions

Can I claim rent or mortgage interest?

Sometimes the answer may differ for home-based businesses, but most employee claims are much narrower and need careful checking.

Can I claim phone and internet separately?

Not if those costs are already covered by the fixed rate method you are using.

Do I need a separate room?

That can depend on the method and the type of expense, so do not assume one simple rule covers every home-office claim.
