Payroll Tax: A State by State Primer for Practices

Payroll tax is the state and territory tax on employer wages above a threshold, and the first thing to internalise is that there is no single set of rules: each state and territory runs its own rates, thresholds and quirks. The principles rhyme across borders; the numbers do not. Current rates and thresholds live with each state revenue office, and quoting last year's figures is how spreadsheets go wrong.

What counts as wages

More than salary. Superannuation contributions, most allowances, bonuses, commissions, directors' fees, the grossed up value of fringe benefits, and termination payments generally fall into the wages net. Exempt items exist and vary by jurisdiction. The definition is broad on purpose, and the audits start from the definition.

Grouping: the provision that surprises everyone

Related businesses can be grouped, and a group shares one threshold, not one each. Common ownership, common employees, tracing through trusts and companies: the grouping provisions are wide, and a client who split operations across two entities for good commercial reasons may discover the threshold they thought they were under twice is available once. When a practice reviews a growing client, grouping is the first payroll tax question, not the last.

Contractors who count as employees

Every jurisdiction deems certain contractor payments to be wages under relevant contract provisions, subject to exemptions that are narrower than clients hope. A business paying the same contractor most days of the year should expect scrutiny. The exemptions are specific and evidence based; assumption is not a defence.

Interstate wages and nexus

Employees working across borders are allocated to a jurisdiction under nexus rules that look at where the work is performed and where the employee is based. Remote work has made this ordinary rather than exotic. A client with staff in three states has three registrations to consider and monthly returns to match.

The rhythm that keeps clients clean

Registration when wages approach a threshold, monthly or annual returns lodged on time, an annual reconciliation that ties payroll records to what was declared, and a standing check on grouping and contractors as the client grows. It is not difficult work; it is relentless work, which is exactly the kind that benefits from a dedicated production lane.
