Side Hustles for Tradies in Australia: Weekend Work, Licences and Tax

Tradies are better placed than almost anyone to earn side income — the skills are in demand and platforms like Airtasker and hipages make finding weekend work easy. But two things separate a smart tradie side hustle from an expensive mistake: state licensing rules (being qualified as an employee doesn’t mean you can legally contract directly with customers), and the ATO’s focus on undeclared cash income in the building trades. Here’s how to do it properly.

What weekend work actually pays

Advertised rates for handyman and general trade tasks on Australian platforms commonly sit between $40 and $90+ per hour, varying by city and trade — licensed trades typically command the top of the range, and customers often book half-day or full-day blocks for job lists. Treat these as gross figures: marketplace fees, fuel, consumables and unpaid quoting time all come out before you’re ahead.

Licensing: qualified isn’t the same as licensed

This is the trap. Holding a trade qualification and working under your employer’s licence Monday to Friday does not authorise you to contract privately with a homeowner on Saturday. Contracting is regulated separately in every state, with dollar thresholds:

Electrical and plumbing work requires the appropriate licence regardless of the job’s value in every state. Other states and territories have their own schemes and thresholds — check your local regulator before quoting any private job. Note the thresholds apply to the whole job (labour plus materials), not just your labour, so a “small” deck can cross the line on materials alone.

Advertising is also regulated — in NSW, for example, it’s an offence to even advertise for residential building work over $5,000 without a contractor licence.

The cash jobs question

Cash payment is legal; not declaring it isn’t. Two reasons the old “cashie” is a bad bet in 2026. First, building and construction consistently ranks among the industries most reported to the ATO’s tip-off line — the ATO received around 43,000 tip-offs in a single year, and unhappy customers, competitors and ex-partners all use it. Second, data matching: businesses in building and construction must lodge Taxable Payments Annual Reports detailing what they paid each contractor, and digital platforms report earnings under the Sharing Economy Reporting Regime, so much of your side income is already visible to the ATO before you lodge.

Declare everything, keep records as you go, and claim your legitimate deductions — tools, consumables and vehicle costs apportioned to the side work. Our side hustle tax time guide covers records and deductions in detail.

ABN, GST and how the income is taxed

Regular, profit-seeking private work means you’re carrying on an enterprise and should hold an ABN — see do you need an ABN for a side hustle for the full picture. GST registration becomes mandatory once GST turnover reaches $75,000, with 21 days to register once you reach or expect to reach it; below that it’s optional.

Side hustle profit stacks on top of your wages, so it’s taxed at your marginal rate — a tradie on $95,000 pays more tax on each side hustle dollar than the headline averages suggest. No tax is withheld from ABN income, so put a percentage of every invoice aside. Our second job vs ABN calculator shows what you’ll actually keep at your income level.

Insurance, super and your day job

Three quieter risks worth as much attention as tax. Insurance: an employer’s public liability and workers compensation generally cover work done for that employer, not your private jobs — a weekend job that goes wrong without your own public liability policy can cost far more than the hustle ever earned. Check whether your tools are covered for commercial use away from your employer’s sites, too. Super: nobody pays it on your sole trader income unless you do — worth factoring in if the side work becomes substantial. Your day job: check your employment contract for secondary employment or non-compete clauses before taking private work, and avoid quoting jobs for your employer’s customers — that’s the fastest way to turn a side hustle into an unemployment story.

Is it worth it?

Done properly — licensed scope, declared income, own insurance — weekend trade work is one of the most reliable side hustles in Australia, because the hourly rates are real and demand is steady. The margin between profitable and pointless is the compliance overhead: if a job would push you over your state’s licence threshold or into work you’re not licensed for, price in getting licensed or pass on the job. The fines, insurance gaps and ATO attention are not worth a few hundred dollars on a Saturday.
