Who this guide is for: Plumbers, apprentices, subcontractors and plumbing business owners in Australia.
Scope note: This guide is broad by design. Employees should focus on unreimbursed work expenses, while sole traders can also claim normal business operating costs.

Quick answer
Plumbers may be able to claim the work-related or business-use share of tools, protective gear, licences, deductible travel, phone use and training connected to their current work. Reimbursements, private travel and ordinary clothing are common non-deductible traps.
- You usually need to have paid the cost yourself.
- The expense should directly relate to earning income or running the business.
- Only the work-related or business-use share is usually claimable for mixed-use items.
- Records matter just as much as the expense itself.
Intro: who this guide is for
Plumbers usually have a solid mix of deductible expenses: tools, safety gear, licensing, vehicle use between jobs, phone costs and training that relates to current work.
Where people get caught is claiming ordinary clothing, personal travel or mixed-use costs without a record that shows the business or work percentage.
Common deductions this occupation may be able to claim
Common expenses to review
- Work tools and equipment such as pipe cutters, inspection tools, wrenches, testing devices and other items you buy yourself for work.
- Repairs and maintenance for tools you own.
- Protective items including boots, gloves, eye protection and other safety gear used because of the plumbing work environment.
- Licence renewals, union fees and professional memberships related to your current work.
- Phone and internet costs used for job calls, supplier contact, dispatch, photos and quoting.
Occupation-specific expenses to review
- Drain camera hire or specialist equipment costs if you pay them yourself as part of the job.
- Travel between separate job sites, to suppliers or to an alternative workplace when the ATO rules allow it.
- Emergency call-out admin, booking software and invoicing costs for subcontractors and business owners.
- Training and compliance costs that maintain or upgrade your existing plumbing skills or licences.
Other costs that may still matter
- Laundry for eligible protective clothing.
- Tolls and parking tied to deductible work travel.
- Bookkeeping, accounting and tax agent fees if you run your own plumbing business.
- Home-based admin costs if you genuinely use part of your home for scheduling and paperwork.
Expenses commonly not deductible
- Normal home-to-work trips in most situations.
- Everyday clothing like plain pants and shirts.
- Private use of a ute, phone or internet service.
- Tools or gear your employer supplied or reimbursed.
- Training that only helps you move into a new occupation rather than your current plumbing work.
Employee vs sole trader or contractor differences
- Employees usually claim unreimbursed expenses tied to earning employment income and should watch reimbursement rules carefully.
- Subcontractors and sole traders usually claim business operating costs, but they also need cleaner records around asset purchases, GST and private use.
- If you move between employee work and side jobs, keep those records separate so you can explain which expense belongs to which income source.
Record-keeping requirements
- Keep purchase records for tools, repairs, PPE, licences and training.
- Hold onto logbook or travel evidence for deductible work travel rather than trying to rebuild trips later.
- Keep a note of any private use percentage for vehicles, phones, internet or equipment used outside work.
- If you buy higher-cost equipment, keep enough detail to support how and when it was deducted.
Common mistakes
- Assuming every ute or van trip is deductible without checking the actual purpose of the trip.
- Claiming ordinary clothes worn on the job instead of protective or compulsory items.
- Claiming the full cost of a phone or vehicle that is also used privately.
- Forgetting that reimbursements or allowances can change how a claim should be treated.
Frequently asked questions
Can plumbers claim tool purchases?

Can I claim my ute for plumbing work?
You may be able to claim the work-related or business-use portion, but not private travel. The way you claim depends on your circumstances and records.
Can apprentices claim work expenses too?
Yes, apprentices can claim eligible unreimbursed work expenses if they paid for them and keep records.
