Why Tradies Overpay Tax Every Year
If you're a tradie — whether you're a plumber, sparky, carpenter, builder, painter, concreter, or any other trade — your work naturally generates a wide range of deductible expenses. Tools, vehicles, protective gear, licences, insurance, training. Done right, these deductions can save you thousands every financial year.
The problem is that most tradies either don't know the full scope of what they can claim, don't keep the records to support their claims, or haven't set up their books in a way that makes deduction tracking automatic.
Many tradies leave thousands of dollars on the table each financial year simply because they don't know what expenses they can claim, or they're unsure whether the ATO will challenge their deductions.
This guide covers every major deduction category available to Australian tradies in 2025–26, the record-keeping rules you need to follow, and a compliance obligation that catches a lot of trades businesses completely off guard: the Taxable Payments Annual Report (TPAR).
The ATO's Three Tests: Every Deduction Must Pass These
Before diving into specifics, here's the framework the ATO applies to every single claim. An expense is deductible if:
- It directly relates to earning your income — not private or domestic in nature
- If it's mixed use, you can only claim the business portion
- You have records to prove it — receipts, invoices, bank statements, or a logbook
If your expense was for both work and private purposes, you can only claim a deduction for the work-related portion. That applies to your ute, your phone, your home internet — anything that crosses over between work and personal life needs to be apportioned.
Now let's go through what you can actually claim.
1. Tools and Equipment
For most tradies, tools are the clearest and most straightforward deduction. The link between a drill, a measuring laser, a pipe wrench, or a circular saw and your income is obvious — but the tax treatment varies depending on the cost.
Items costing $300 or less: You can claim an immediate deduction in the year of purchase, provided the item is used mainly for work and is not part of a set that collectively costs more than $300.
Items costing more than $300 (general rule): You claim the decline in value over the item's effective life using either the prime cost or diminishing value method.
Items under $20,000 (instant asset write-off — act before 30 June 2026): The instant asset write-off allows eligible small businesses with under $10 million annual turnover to claim a full deduction for single assets costing up to $20,000, provided the asset is first used before 30 June 2026.
This is a significant opportunity. A tradie who purchases a $15,000 nail gun system, an $8,000 laser level kit, and a $12,000 compressor before 30 June 2026 can write off all three immediately — because each asset is individually below the $20,000 threshold, even though the combined spend is $35,000.
Critical: From 1 July 2026, this threshold reverts to $1,000. If you've been sitting on the fence about a major tool or equipment purchase, this financial year is the time to act.
You can also claim the cost of repairing existing tools and equipment, as well as replacement parts.
2. Vehicle and Travel Expenses
For tradies, vehicle costs are typically the largest single deduction category — and also one of the most frequently audited. Getting this right matters.
The ATO offers two methods:
The Logbook Method
You keep a written record of all vehicle journeys over a continuous 12-week period, noting the date, distance, destination, and purpose of each trip. This establishes a business-use percentage that applies to all actual running costs for the full year — fuel, registration, insurance, servicing, loan interest, and depreciation. The logbook method has no annual kilometre cap and is generally the better option for tradies who clock significant business kilometres.
Logbooks are valid for five years, provided your business travel pattern doesn't change significantly. If your logbook is older than five years, you need a new one.
The Cents Per Kilometre Method
You claim a fixed rate of 88 cents per kilometre for business travel (2024–25 rate, updated annually), capped at 5,000 kilometres per year. No logbook required, but you do need to be able to demonstrate how you calculated the kilometres.
The home-to-work rule that catches tradies out: Driving from your home to your first job site is generally treated as private travel — not deductible — unless you are transporting bulky tools that cannot be stored at the worksite and there is no secure storage available there. The ATO scrutinises this claim closely. If you have a legitimate reason to transport heavy or bulky equipment from home every day, document it carefully.
Travel between job sites during the day, from a job site to a supplier, or from the office to a client's premises is deductible.
3. Protective Clothing and Safety Equipment
You can claim a deduction for protective clothing or items that have features or functions to protect you from specific risks of injury or illness at work. This includes protective and safety equipment such as safety glasses, safety helmets and earmuffs, or sunscreen, sunhats and sunglasses where you are required to work outdoors.
Specific deductible items include:
- Steel-capped boots and safety shoes
- Hi-visibility vests and workwear
- Hard hats and safety helmets
- Ear protection (earmuffs, earplugs)
- Protective gloves
- Safety glasses and goggles
- Dust masks and respirators
- Sunscreen and protective clothing for outdoor workers
- Work uniforms that include your business logo
What's not deductible: Conventional clothing that could be worn outside of work — even if you only wear it on the job — is not deductible. A plain pair of work shorts is not deductible. Steel-capped boots with your business logo or name are deductible. The distinction is whether the item has a protective function or is occupation-specific.
You can also claim the cost of laundering work clothing. The ATO allows laundry claims without receipts if the total claim is under $150 per year.
4. Licences, Registrations, and Union Fees
Any licence or certification required to legally perform your trade is deductible. This includes:
- Trade licences (electrical licence, plumbing licence, builder's licence, etc.)
- White card (construction induction card) and renewal costs
- Working at Heights certification
- First aid certificate renewals (where required for your work)
- Any industry registration renewal fees
Union dues and industry association memberships — Master Builders, HIA, Master Electricians Australia, NECA, and similar bodies — are also fully deductible.
5. Insurance Premiums
Insurance costs directly related to your business are fully deductible. For tradies, these commonly include:
- Public liability insurance — typically a mandatory cost for any tradie operating on someone else's property
- Tools and equipment insurance — contents and portable equipment cover
- Income protection insurance — the portion that protects your income from injury or illness
- Workers' compensation — if you have employees
- Professional indemnity — for design and construct or project management roles
- Vehicle insurance — for business-registered vehicles, or the business-use portion of a mixed-use vehicle
Keep every policy renewal notice as a record. Your insurance costs for the year should be clearly visible in your business bank account and bookkeeping records.
6. Phone and Internet
If you use your mobile phone for work — quoting jobs, communicating with clients, ordering materials, photographing worksites — you can claim the work-related portion of the cost.
The same applies to your home internet connection if you use it for business purposes (emails, invoicing, scheduling software, etc.).
The key is apportionment. You can't claim 100% of your phone bill unless 100% of your usage is genuinely work-related. Most tradies are expected to keep a four-week diary at some point during the year to establish their business-use percentage, which can then be applied to the full year's costs.
7. Materials, Consumables, and Supplies
The ATO recognises that for tradespeople, the cost of raw materials and consumables forms a substantial part of day-to-day operational expenses, and allows a full deduction for the cost of materials and supplies used to complete jobs and generate income.
Consumables — items used up in the course of a job rather than lasting assets — include screws, nails, solvents, lubricants, sandpaper, welding gas, drill bits, paintbrushes, sealants, caulk, cable ties, and similar items. These are claimed in full in the financial year you purchase them.
For materials purchased for a specific job and included in a client quote, your bookkeeping needs to clearly separate the cost of those materials from your general business expenses to avoid double-counting income and expenses.
8. Training and Professional Development
Courses, workshops, and certifications that maintain or improve your skills in your current trade are deductible. Examples include:
- Trade-specific upskilling (e.g., a plumber completing a gasfitting licence)
- Safety and compliance training (working at heights, confined spaces, asbestos awareness)
- Software training for tools you use in your business (estimating software, job management platforms)
- Business and financial management courses relevant to running your trade business
The important limitation: training must relate to your existing trade or business. A carpenter doing a real estate sales course is not deductible — that's preparing for a new career, not improving your current one.
9. Subcontractors and Hired Labour
If you bring in subcontractors to complete parts of a job, the amounts you pay them are fully deductible as a business expense — provided you follow the ATO's rules.
The critical factor is that the subcontractor must have a valid Australian Business Number (ABN) and provide you with a compliant tax invoice for their work. Without a valid ABN, you may be required to withhold tax from the payment at the top marginal rate under the PAYG withholding rules.
Always collect your subcontractor's ABN before paying them. If they don't provide one, withhold 47% of the payment and remit it to the ATO. This is a legal obligation — not optional.
Distinguishing between a subcontractor and an employee is also critical. Getting this wrong can lead to significant penalties including back-paid superannuation, PAYG liabilities, and interest charges. If someone works exclusively for you, under your direction, using your tools, and is integrated into how your business operates — the ATO may treat them as an employee regardless of how you've structured the arrangement.
10. Marketing, Advertising, and Business Costs
Other fully deductible business costs for tradies include:
- Website and online presence — hosting, domain fees, website design
- Advertising — Google Ads, Facebook/Instagram ads, print flyers, vehicle signage
- Estimating and job management software — Fergus, ServiceM8, Buildxact, and similar tools
- Accounting and bookkeeping fees — yes, what you pay Girl Friday Australia is fully deductible
- Bank fees and merchant charges — any EFTPOS or payment processing fees
- Work-related postage and stationery
- Office expenses if you maintain a home office or business premises
The Compliance Obligation Most Tradies Don't Know About: TPAR
This is the part that catches a significant number of trades businesses off guard every year.
If your business operates in the building and construction industry and more than 50% of your total business income comes from construction services, you are required to lodge a Taxable Payments Annual Report (TPAR) with the ATO each year.
What Is a TPAR?
The TPAR is an Australian reporting requirement created in response to concerns about widespread tax evasion among contractors in the building and construction industry. It requires businesses to report payments made to contractors and subcontractors, giving the ATO a direct line of sight into contractor income.
In plain terms: if you pay subcontractors to work on jobs for you, you must report every payment you made to each of them over the financial year to the ATO. The ATO then cross-references this data against the income each contractor declared on their own tax return.
In a recent reporting cycle, the ATO used TPAR data to identify over $400 million in undeclared income. This is not a light-touch compliance requirement — it's an active enforcement tool.
Who Needs to Lodge?
The TPAR requirement applies to businesses in the following industries where contractor payments are common:
- Building and construction (50%+ of income threshold applies)
- Cleaning (10%+ of income threshold applies)
- Courier and road freight services (10%+ threshold)
- IT services (10%+ threshold)
- Security, investigation, and surveillance services (10%+ threshold)
If your business provides these services and pays contractors to deliver them, you may need to lodge a TPAR. If TPRS services are only part of the services your business provides, you need to work out what percentage of the payments you receive are for TPRS services each financial year. If 10% or more of your business income comes from these services, you must lodge a TPAR.
For most builders, plumbers, electricians, and similar trades, the 50% threshold for construction services is met as a matter of course. If you are regularly paying subbies, you almost certainly need to lodge a TPAR.
What You Need to Report
For each contractor, you need to report their ABN, name, address, and total gross payments made during the financial year — including the GST component.
This means you need to have recorded this information throughout the year — not tried to reconstruct it in August from memory and a pile of invoices. Every time you pay a subcontractor, their invoice needs to be correctly entered into your accounting system with their ABN captured.
When Is the TPAR Due?
A TPAR must be lodged by 28 August each year for the preceding financial year. For the 2025–26 financial year, your TPAR covering all contractor payments from 1 July 2025 to 30 June 2026 must be lodged by 28 August 2026.
Failure to lodge on time attracts penalties from the ATO — and consistently missing the TPAR is the kind of compliance gap that invites broader scrutiny of your tax position.
The ATO matches the information you provide in your TPAR against the income reported by the contractors on their own tax returns. If your figures don't align, it flags a discrepancy that can invite further investigation.
What Records Do You Need?
Collect from every subcontractor before paying them:
- Their full legal name or business name
- Their ABN
- Their address
- A compliant tax invoice showing the services provided, total amount, and GST component
Keep these records in your bookkeeping system throughout the year. Most modern accounting software — including Xero and MYOB — has built-in TPAR reporting that generates the report from correctly coded contractor payments, making lodgement straightforward if your books are accurate.
The Record-Keeping Rules You Must Follow
No matter what you're claiming, the ATO requires records that can substantiate the claim. For most expenses, this means a receipt or tax invoice showing:
- The name of the supplier
- The date of the purchase
- The amount (including GST if applicable)
- A description of what was purchased
After you've lodged your tax return for the year, you must keep your records for a minimum of 5 years. Digital copies are accepted — taking a photo of a receipt with your phone and saving it to a cloud folder or your accounting software is perfectly compliant.
Vehicle logbooks must be kept for the same five-year period after the last year you relied on them. If your logbook has expired and you're claiming vehicle expenses under the logbook method, you need a new one.
The most common record-keeping failure the ATO sees is tradies who claim significant vehicle, phone, or tool expenses without adequate documentation. It's not that these expenses aren't real — it's that they can't be proven. A deduction you can't substantiate is a deduction you can't keep if the ATO reviews your return.
Avoid These Common Tradie Tax Mistakes
Claiming home-to-work travel without a valid reason. The ATO is firm: commuting is private. Unless you're transporting genuinely bulky equipment that can't be stored at the site, the drive from home to work doesn't count.
Claiming 100% of a mixed-use vehicle. If you use your ute personally on weekends, you can't claim 100% business use. Logbooks exist precisely to capture the real split — and the ATO can tell when someone has claimed an inflated business-use percentage.
Forgetting the TPAR. This is the big one. Builders and subbies who regularly engage other subcontractors and don't lodge the TPAR are exposed to penalties and ATO audit risk.
Not separating business and personal finances. Blurring the line between personal and business spending is a common issue, especially for sole traders. Claiming private expenses as business deductions can trigger ATO scrutiny.
Losing receipts. The simplest fix: photograph every receipt the moment you get it and store it digitally. There's no excuse in 2026 for losing paper records when your phone can capture and upload in seconds.
Why Clean Books Are the Foundation of Every Tradie's Tax Position
Every deduction in this guide is legitimate. The ATO doesn't dispute that tradies buy tools, use vehicles, pay subs, and wear safety gear. What the ATO disputes — and what audits are built around — is whether you can prove it.
That proof comes from your books. If your accounts are reconciled monthly, your subcontractor payments are correctly entered with ABNs captured, your vehicle logbook is current, and your receipts are attached to the relevant transactions in your accounting software, you can claim every legitimate deduction with confidence.
If your books are a mess — transactions uncoded, subbie payments recorded as lump sums with no detail, vehicle expenses estimated from memory — you're not just at risk of an ATO review. You're almost certainly underclaiming, because you can't clearly see what you've spent.

Frequently Asked Questions
Can I claim my ute on tax if I use it for both work and personal trips? Yes — you can claim the business-use portion. Under the logbook method, you keep a 12-week travel diary to establish your business-use percentage, then apply that to all running costs. Under the cents per kilometre method, you claim 88c per km up to 5,000 kilometres per year with no logbook required.
Do I need to lodge a TPAR if I only used one subcontractor this year? If your business is in a TPAR-reportable industry and the payment was for a reportable service, yes — the obligation applies regardless of how many contractors you used. Even one payment needs to be reported if the threshold is met.
What happens if I lodge my TPAR late? The ATO applies penalties for late TPAR lodgement. The penalty amount depends on the size of your business and how late the report is. Lodging late but voluntarily is treated more favourably than being caught not lodging at all.
Can my bookkeeper lodge the TPAR on my behalf? Yes — as a registered BAS agent, Girl Friday Australia can prepare and lodge your TPAR directly with the ATO on your behalf. We track your contractor payments throughout the year so that August 28 isn't a scramble.
What if a subcontractor doesn't give me their ABN? You are required to withhold 47% of the payment and remit it to the ATO under the no-ABN withholding rules. You should not make payments without an ABN — always collect this information before engaging a contractor.
