The Jump from Sole Trader to Employer
Hiring your first employee is a significant milestone for a Melbourne trades business. It's also the moment that most small operators discover they have more compliance obligations than they expected — and that getting them wrong has real consequences.
This guide covers everything a Melbourne tradie needs to set up before the first pay run.
1. Obtain a Tax Withholding Obligation
As soon as you have an employee, you are required to withhold PAYG (Pay As You Go) tax from their wages and remit it to the ATO. The amount withheld depends on the employee's annual income and their tax file declaration. To do this legally, you need to:
- Register for PAYG withholding with the ATO (if you haven't already — most businesses already have this through their ABN registration)
- Collect a Tax File Number declaration from your employee before their first pay
- Use the ATO's withholding tables (or Xero Payroll) to calculate the correct withholding amount
2. Register with WorkSafe Victoria
Once you employ someone in Victoria, you must register with WorkSafe Victoria for WorkCover insurance. This is a legal requirement that must be completed before the employee starts work — not after.
Your WorkCover premium is calculated as a percentage of your industry classification rate applied to your total remuneration. For trades businesses in Melbourne, the construction industry rate is one of the higher classifications.
At the end of each financial year, you declare your actual wages to WorkSafe Victoria and your premium is adjusted. Correct payroll setup in Xero ensures this figure is accurate.
3. Confirm the Correct Award
Most trades employees in Melbourne are covered by a Modern Award under the Fair Work Act. The Award sets:
- Minimum pay rates (by classification and level)
- Overtime and penalty rates
- Allowances — tool allowance, travel allowance, dirty work allowance, height allowance
- Leave entitlements
The most common Awards for Melbourne trades businesses:
- Building and Construction General On-site Award — builders, carpenters, concreters, plumbers (domestic)
- Electrical, Electronic and Communications Contracting Award — electricians
- Plumbing and Fire Sprinklers Award — plumbers and gas fitters (commercial/industrial)
Underpaying Award rates — even accidentally — is a Fair Work violation. The Fair Work Ombudsman actively investigates the construction industry. Getting the classification right from the start protects you from back-pay claims later.
4. Set Up Single Touch Payroll (STP) in Xero
Single Touch Payroll is mandatory for all Australian employers, including sole traders with one employee. Every pay run must be reported to the ATO in real time through STP-enabled software.
STP Phase 2 — mandatory since January 2022 — requires expanded reporting including income type, disaggregated gross, and more detailed super information. Xero Payroll handles all of this automatically when configured correctly by a Xero Certified Advisor.
5. Set Up Superannuation — and Mark Your Calendar for Payday Super
The Superannuation Guarantee (SG) rate is currently 11.5% of ordinary time earnings. You are required to:
- Calculate super correctly on ordinary time earnings (not overtime)
- Lodge via SuperStream — the ATO's electronic super payment system
- Pay by the quarterly due dates: 28 October, 28 January, 28 April, 28 July
From 1 July 2026, Payday Super requires super to be paid on each payday — not quarterly. This is a significant change for businesses with manual payroll processes. Xero Payroll handles super calculation and lodgement, making the transition manageable.
Late super attracts the Superannuation Guarantee Charge (SGC) — which includes the unpaid super, interest, and an administration fee. Unlike regular super, SGC is not tax deductible. It is expensive to get wrong.
6. Understand the Payroll Tax Threshold for Victoria
Victorian payroll tax applies once your total wages exceed the annual threshold — currently $900,000 per year. For most Melbourne trades businesses with one or two employees, payroll tax won't apply. However:
- If you engage labour hire contractors who are treated as employees for payroll tax purposes, their payments may count toward the threshold
- If your business is part of a group (related entities), the threshold is shared across the group
Most small trades businesses don't need to worry about payroll tax initially. It's worth knowing the threshold so you're not caught off-guard as you grow.
7. Set Up Payroll in Xero Before Day One
Don't run your first pay in a spreadsheet and promise to put it into Xero later. Set Xero Payroll up correctly before the first pay run:
- Employee record with TFN, start date, pay rate, and classification
- Correct Award pay template (or manual rates confirmed against Award)
- Leave entitlements configured
- Super fund selected and SuperStream connected
- STP Phase 2 enabled
