Tradie Tax Returns — from $79
Tools, vehicles, PPE, union fees, and licences were all claimed correctly in accordance with ATO guidelines. From $79 with a fixed quote before we start. Not confident in previous returns? Second Look costs nothing if we find nothing.
GST Registration and BAS Lodgement
Compulsory above $75,000 turnover. Below that, voluntary registration lets you claim GST back on tools, materials, and vehicle costs. We advise on the right decision, register you, and lodge your quarterly BAS on time.
Vehicle Logbook and Deduction Review
Logbook method versus cents per kilometre most full-time tradies leave thousands on the table using the wrong method. We review your vehicle deduction and set up a compliant logbook from day one.
Sole Trader Tax Obligations and Planning
Your business income is taxed at your personal marginal rate up to 47%. A company pays 25% on the same income. We advise on PAYG instalments, structure review, and when the switch to a company structure makes financial sense.
Superannuation for Sole Trader Tradies
Personal super contributions up to $30,000 per year are tax-deductible for sole traders — and almost nobody claims them. A $10,000 contribution at 32.5% saves $3,250 in tax while building your retirement balance.
Bookkeeping for Tradies Businesses
Employees, subcontractors, and multiple vehicles Xero-connected to your bank; invoice templates set up; payroll managed; and a monthly picture of where your money is going, so BAS time is never stressful.
What Our Clients Say (Real Adelaide Stories)
J. Ferreira
Adelaide, Australia
I have been a sole trader electrician for six years and had no idea I could claim my personal super contributions as a tax deduction. The Kalculators reviewed my last three returns, amended two years, and I got back more than $4,000 in refunds.
Now I make super contributions every year and claim them properly
What Can Tradies Claim on Their Tax Return?
The ATO's deduction guidelines for building and construction workers set out what is claimable, but the details of what counts as immediate deduction versus depreciation, and what requires a logbook versus a receipt, are where most self-lodging tradies either miss claims or overclaim. Here is the full picture:
| Deduction | What qualifies | Key rule |
|---|---|---|
| Tools under $300 | Hand tools, power tools, and measuring equipment are fully deductible in the year of purchase | Immediate, no depreciation |
| Tools over $300 | Larger equipment depreciated over the effective life at ATO rates | Cannot claim full cost in one year |
| Vehicle logbook method | Work-use proportion of fuel, insurance, registration, servicing, depreciation | 12-week logbook required. No distance cap |
| Vehicle cents per km | 88 cents per km for work travel. Simple, no logbook. | Capped at 5,000km = $4,400 max |
| Personal protective equipment | Hard hats, steel cap boots, safety glasses, high-vis vests, gloves, and hearing protection | Must be for work use only |
| Work clothing with a logo | Uniforms with an employer logo or protective function are deductible. Plain work clothes are not. | Plain clothes NOT deductible |
| Laundry of work clothing | $1 per load for qualifying work clothing. Up to $150 without receipts. | Receipts needed above $150 |
| Phone and internet | Work-use proportion of the mobile plan and handset. Usage diary or reasonable estimate required. | Proportion only, not 100% |
| Union fees and licences | CFMEU, ETU, AMWU and other union dues. Trade licence renewals, white card, and first aid certificates. | Fully deductible |
| Home office (admin) | Proportion of home internet used for quoting, scheduling, and admin. Fixed rate 67c per hour method or actual cost. | Cannot claim if no dedicated workspace |
| Super contributions (self-employed) | Personal super contributions up to the $30,000 concessional cap. Must lodge Notice of Intent with the super fund first. | Very commonly missed |
| Training and upskilling | Courses directly related to your current trade. Not career-change courses. | Must be trade-specific |
Been doing your own returns and not claiming all of this? Our Second Look Assessment reviews up to three years of past returns at no upfront cost. If we find missed deductions, we amend. If we do not, the review costs you nothing.
How Tax Works as a Sole Trader Tradie in Australia
This is the question most tradies going ABN for the first time want answered clearly. Here is how it actually works.
Sole trader tax - the basics for tradies
As a sole trader, ALL your business income is added to any other income you have and taxed at your personal marginal tax rate. There is no separate business tax rate.
2025-26 individual tax rates (after Stage 3 tax cuts):
- $0 to $18,200: 0% (tax-free threshold)
![icon]()
- $18,201 to $45,000: 19%
![icon]()
- $45,001 to $120,000: 32.5%
![icon]()
- $120,001 to $180,000: 37%
![icon]()
- Over $180,000: 45%

- Plus 2% Medicare Levy on income above the low-income threshold

As a sole trader, ALL your business income is added to any other income you have and taxed at your personal marginal tax rate. There is no separate business tax rate.
PAYG instalments: once your tax from sole trader income reaches a threshold, the ATO requires you to pay quarterly PAYG instalments
rather than waiting until you lodge your return. This prevents a large unexpected tax bill at year end. We calculate your quarterly instalment amounts and advise whether to vary them up or down based on your actual income for the year.
