Deductions – Cleaning of work clothing

You can claim the costs of washing, drying and ironing eligible work clothes, or having them dry-cleaned.

You must have written evidence, such as diary entries and receipts, for your laundry expenses if both:

• the amount of your claim is greater than $150, and
• your total claim for work-related expenses exceeds $300

If you don’t need to provide written evidence for your laundry expenses, you may use a reasonable basis to work out your claim. For washing, drying and ironing you do yourself, we consider that a reasonable basis for working out your laundry claim is:

• $1 per load – if the load is made up only of work-related clothing, and
• 50 cents per load if other laundry items are included.

If you choose a different basis to work out your claim, we may ask you to explain that basis.
