The ATO allows you to claim deductions for expenses directly related to earning your income. You must have actually paid the expense, not been reimbursed, and have a record to prove it.

Tools and Equipment

Any tool or piece of equipment purchased for your plumber work is tax deductible. Under Instant Asset Write-Off rules, many items can be claimed in full in the year of purchase — confirm the current threshold with your accountant.

  • Pipe cutters, benders and soldering equipment
  • Thread taps and dies
  • Drain cameras and inspection equipment
  • Hydro-jetting equipment
  • Pressure testing tools
  • Pipe wrenches and fittings tools
  • Torch and gas equipment
  • Tool van racking and storage
  • Replacement parts and consumables used in your work
  • Tool repairs and maintenance costs

Tip: Photograph every receipt immediately using Dext — it extracts and stores receipt details automatically. The ATO audits up to 5 years back.

Vehicle Expenses

Your vehicle is typically your largest tax deduction as a plumber. The logbook method delivers the best result — keep a 12-week ATO logbook, establish your business-use percentage, and apply it to all annual vehicle costs: fuel, registration, insurance, loan interest, servicing and depreciation.

Licences, Training and Memberships

  • Plumber registration (state licensing authority), Gasfitting licence renewal, Backflow prevention certification, Plumbing industry association membership, White Card renewal, Restricted electrical work certificate (where applicable)
  • First aid and CPR certificate renewal
  • Any industry-relevant CPD or upskilling courses

Clothing, PPE and Safety Gear

Safety equipment, protective gear and branded uniforms are deductible. Standard everyday clothing is not — even if worn only for work. Deductible items include steel-cap boots, high-visibility clothing, hard hats, protective gloves, safety glasses, hearing protection and clothing featuring your business logo. Laundry costs for deductible workwear are also claimable.

Phone, Internet and Home Office

Claim the work-use percentage of your mobile phone plan and internet bill. If you do administrative work from home — quoting, invoicing, scheduling — claim home office costs using the ATO fixed rate method (67 cents per hour worked at home).

Insurance Premiums

All business insurance is fully tax deductible: public liability, tools and equipment insurance, income protection and workers compensation. Compare tradie insurance options →

Can a plumber claim their van or ute?

Yes — a vehicle used to carry tools and travel between job sites is deductible. Use the logbook method for the maximum claim. Keep a 12-week ATO logbook, calculate your business-use percentage, then apply it to all annual vehicle costs.

What records do I need to keep?

Keep receipts for all claims over $10. For vehicle claims, maintain a logbook and all expense records. The ATO requires records for 5 years from the lodgement date. Digital copies are accepted — apps like Dext make this easy.

Is accounting software tax deductible?

Yes — subscriptions to Xero, Rounded and MYOB are fully deductible business expenses. So is the cost of your accountant or bookkeeper.
