Tips for claiming home-based business expenses this tax time

Make the most of your home-based business expenses by understanding what deductions you can and can’t claim.

Published 28 July 2026

If you run your small business from home, tax time is a good opportunity to make sure you’re claiming the deductions you’re entitled to.

Depending on your circumstances, you may be able to claim the decline in value of depreciating business assets (such as laptops, desks and office furniture) or running expenses associated with operating your business from home. This includes:

  • electricity for heating, cooling and lighting
  • phone and internet expenses
  • office cleaning costs.

Work out your expenses

Many home-based business owners use the fixed rate method to calculate their work-from-home running expenses. This method allows you to claim a set rate per hour worked from home and can simplify record keeping. Keep in mind that some expenses are already covered by the fixed rate and can’t be claimed separately.

If you have a dedicated area in your home that is used as a genuine place of business, you may also be able to claim occupancy expenses. This may include rent, mortgage interest, council rates, land taxes or home insurance. Eligibility depends on your individual circumstances.

Whatever method you use, remember you can only claim the business portion of your expenses, and you’ll need records to support your claims.

Keep good records

Good record keeping throughout the year can make it easier to prepare and lodge your tax return. You need to keep most records for 5 years, so you should store them in a safe place. They should also be written in English or easily converted to English.

Check if CGT applies

It’s important to remember, when running your business from home, you may be liable for capital gains tax (CGT) when selling your home. If eligible, you may be able to reduce your CGT by applying the small business CGT concessions.
