Nobody became a tradie because they love paperwork. You got into the game because you're good with your hands, you like seeing a job done properly, and the idea of sitting in an office under fluorescent lights for forty years sounds like a slow death.

Fair enough.

But here's the thing about being a sole trader or running a small trade business in Australia: the ATO is not your enemy, but they're absolutely not your accountant either. They're not going to chase you down and say "excuse me, did you know you could've claimed that?" They'll just quietly take more of your money while you assume everything is above board.

Every year, tradies all over the country hand back thousands of dollars they were legally entitled to keep. Not through anything dodgy. Just through not knowing what they can claim.

So let's fix that.

First, the Basics

Before we get into the stuff people miss, let's make sure the obvious ones are locked in. You'd be surprised how many tradies still aren't claiming all of these.

Tools and equipment. Yes, obviously. But are you claiming all of it? Every drill bit, every replacement blade, every extension lead, every tool bag? The small stuff adds up to serious money across a year, and a lot of it gets bought in cash at the hardware store and never recorded anywhere. According to the ATO's occupation guide for tradies, tools and equipment used for work purposes are deductible, provided you have a receipt to prove it.

Work vehicle costs. Either claim the actual expenses (fuel, rego, insurance, servicing, tyres) or use the ATO's cents per kilometre method for business travel. Either way, keep a logbook or you're guessing, and guessing is how you get audited. The ATO requires a 12-week continuous logbook to calculate your business use percentage. You only need to do it once every five years, or when your usage pattern changes significantly.

Phone and internet. You're using your phone for work. Quotes, calls, emails, photos, navigating to sites. A portion of your phone bill and home internet is claimable. Most tradies either forget this entirely or claim 100% when they should be claiming a reasonable work percentage. The ATO's guidance on apportionment is clear: you can only claim the business slice, but for tradies using their phone heavily for work, that percentage is often legitimately high.

Protective clothing and uniforms. Steel caps, high-vis, safety glasses, knee pads, work gloves. The ATO confirms that protective clothing and safety equipment with a specific work function is deductible. Your regular jeans and a flanno are not. But most of what you actually wear on site probably is.

Now the Ones People Actually Miss

1. The Home Office

If you do any admin from home, and you do even if you don't think of it that way, you can claim a portion of your home running costs. Electricity, internet, phone, and potentially rent or mortgage interest if you have a dedicated workspace.

The ATO's fixed rate method currently sits at 67 cents per hour worked from home (ATO, home-based business expenses). This covers electricity, internet, and phone costs in one simple rate. You don't need to have a room set aside exclusively for work to use this method. You just need to record your hours.

Most tradies file this as zero because it feels complicated. It's not. Keep a rough diary for four weeks as a representative sample and you're sorted.

Important caveat: if you want to claim occupancy expenses like mortgage interest or rent, the ATO requires the space to genuinely qualify as a "place of business" - clearly identified, not easily adaptable to private use. This is a higher bar and worth discussing with a registered tax agent before claiming.

2. Training, Tickets, and Licences

Every ticket you renew costs money. Every course you do costs money. If it's related to maintaining or improving skills in your current trade, it's deductible.

White card renewals. Working at heights. Confined space. First aid. EWP. Any industry-specific certification you need to be on site. According to Driversnote's guide to sole trader deductions, self-education expenses are claimable as long as they're directly related to your current business activities and either maintain or increase your income potential in that field.

What's not deductible is training for a completely new career. But anything that keeps you qualified and competitive in the work you're already doing? Claim it.

3. Subscriptions and Software

This one's growing every year as more tradies use apps and software for their business. Quoting software, job management platforms, invoicing tools, accounting software. If you're paying a subscription for something you use in the business, it's deductible.

QuickBooks' tax guide for Australian tradies confirms that business software subscriptions are claimable expenses, provided they're directly related to earning your income. Keep the receipts (most come via email), and make sure you're actually claiming them. A lot of tradies sign up for tools, use them, and then forget they're even paying for them, let alone claiming them.

4. Bank Fees and Interest on Business Expenses

If you use a credit card or a line of credit to buy tools or materials for a job, the interest on that borrowing is deductible. If you have a business bank account, the fees are deductible.

This sounds small. Individually, it is. But across a year it adds up, and it takes two minutes to sort out with your accountant if you've got the records. The ATO's guidance for sole traders confirms that most ordinary business expenses incurred in earning your assessable income are deductible, including finance costs.

5. Union Fees and Industry Association Memberships

Member of your trade union? Paying fees to a professional association? That's deductible in full. A lot of tradies pay these automatically and never think to mention them at tax time because it doesn't feel like a "business expense." It absolutely is. The ATO's tradesperson guide lists union fees and professional memberships as legitimate work-related deductions.

6. The Ute That Doubles as Everything

Your work vehicle is probably your biggest deduction and also your most complicated one. The mistake tradies make is either:

a) Claiming less than they're entitled to because they assume the ATO will query anything high.

b) Claiming 100% when there's clearly some personal use, which is how you end up in an uncomfortable conversation with the ATO.

Keep a proper logbook for 12 continuous weeks. That percentage then applies to all your vehicle running costs for the year including fuel, servicing, tyres, insurance, rego, loan interest, and depreciation. According to Latitude Accountants, the ATO requires this 12-week logbook to legitimately calculate your business use percentage under the logbook method.

If your vehicle is used almost exclusively for work, your business use percentage is probably legitimately very high. Don't undersell it just to play it safe.

7. The Instant Asset Write-Off

When you buy something expensive, a trailer, a generator, a big piece of test equipment, you'd normally depreciate it over its useful life. But here's what a lot of tradies miss.

The $20,000 Instant Asset Write-Off is currently available until 30 June 2026. According to the ATO's official guidance, small businesses with an aggregated turnover under $10 million can immediately deduct the full cost of eligible depreciating assets costing less than $20,000, in the year the asset is first used or installed ready for use.

That limit applies per asset, so you can write off multiple items in the same year. The asset can be new or second-hand, and it just needs to be used or installed ready for use before 30 June 2026.

After 1 July 2026, the threshold is currently set to drop back to $1,000 unless the government extends it again, so if you've been thinking about new gear, timing matters. This is genuinely worth a conversation with your accountant before you make a big purchase.

8. Sunscreen and Skin Protection

Yes, really. If you work outdoors, sunscreen and sun hats worn as protective equipment on site are deductible expenses. The ATO confirms this directly: "sunscreen, sunhats and sunglasses where you are required to work outdoors" are claimable.

It won't retire you early. But it's yours. Claim it.

The Record-Keeping Thing (Sorry, But It Matters)

None of this helps you if you can't prove it. And "I'm pretty sure I spent about that much on fuel" is not proof.

The ATO is clear on this: you must have a receipt or other written evidence from the supplier, showing what was purchased, when, and for how much. Bank statements alone usually won't cut it. And you need to keep records for a minimum of five years after lodging your return.

The simplest system that actually works for tradies on the tools:

One business bank account or credit card. All business expenses go through it. At tax time, your accountant can see everything in one place without you digging through your personal account trying to remember what was work and what was your mate's birthday dinner.

A folder in your email or phone for receipts. Photo the receipt in the hardware car park. Forward the email receipt to a dedicated folder. Takes ten seconds. The ATO's own app has a myDeductions tool specifically for this, which logs expenses and stores photos directly.

A rough mileage log. Even a note in your phone works. "Monday 14 April, Ringwood to Doncaster, 22km." You don't need every trip, just enough to calculate your work percentage accurately.

That's it. That's the whole system.

What a Tradie-Focused Accountant Can Actually Do For You

General accountants are fine for simple returns. But a good accountant who works with tradies regularly will know the industry-specific deductions that a general practitioner might not think to ask about. The cost of a registered tax agent is itself a deductible expense, per the ATO.

If yours just plugs in numbers and doesn't ask what you spent on tools, training, or your vehicle, it might be worth shopping around.

One Last Thing

None of this is financial advice. Tradie Assistant is a software company, not an accounting firm, and ATO rules change regularly. Before you claim anything significant, run it by a registered tax agent who knows the trade sector.

But do have that conversation. And when you sit down with them, ask: "What deductions do tradies in my situation commonly miss?"

The answer might surprise you.
