Plumber

Tax deductions and GST advice for self-employed plumbers in Australia.

Allowable Expenses

• Heavy Machinery & Tools — Drain cleaners, pipe cutters, and cameras. Use depreciation for expensive items.
• Work Vehicle — Running costs for your ute or van used to transport materials and tools.
• Safety Gear — Overalls, gloves, and protective eyewear.
• Home Office — A portion of phone and internet for managing bookings and quotes.

Tax Tips

• Material costs for jobs are fully deductible.
• Professional indemnity insurance is a must and fully deductible.
• Apprenticeship costs may be deductible if related to your current role.
• Review your business-use logbook percentage each year — if your work pattern changes significantly, you must complete a new 12-week logbook to maintain the correct vehicle deduction.

Frequently Asked Questions

Can I claim for meals while working?

Generally no, unless you are traveling overnight for business.

Is my van insurance deductible?

Yes, to the extent it is used for business purposes.

How do I claim materials I buy for client jobs?

Materials purchased specifically for a client job are a deductible cost of sales. Keep the supplier tax invoice and a record of which job the materials were used on. If you are registered for GST, you claim the GST credit on the BAS and include only the net cost as a deduction in your tax return.

Can I claim income protection insurance as a plumber?

Yes. Unlike the UK and Ireland, income protection insurance premiums are tax-deductible in Australia for self-employed tradespeople. If you make a claim and receive payments under the policy, those payments are assessable income — so you will pay tax on them.
