Payroll Tax
Australian Business & ComplianceAlso: State payroll tax
Quick definition
Payroll tax is a state and territory tax on the total wages a business pays once that wage bill crosses a threshold. Each state sets its own threshold and rate. For marketers it is a hidden on-cost that makes growing an in-house team more expensive than headline salaries suggest, and it lands unevenly depending on where you employ people.
How it varies across Australia
Payroll tax creates a quiet inflection point. Below the threshold a business pays none, so early hires feel cheap. Cross it and every wage dollar above the line attracts the tax, so the cost of the next marketer steps up just as a growing business is leaning into headcount.

Payroll tax is a tax on wages, charged by the states and territories rather than the federal government. A business only pays it once its total wage bill passes a threshold, and then it applies to wages above that line at the state's rate.
The important features for planning are that it is thresholded and that it varies by state. Each state and territory sets its own threshold and its own rate, so the same team can attract different payroll tax depending on where the people are employed. Wages are also grouped across related entities, so splitting a business into parts does not avoid it.
For marketers the relevance is the cost of an in-house team. Payroll tax is one of the on-costs, alongside superannuation and leave, that sit on top of salary. Below the threshold a team feels cheap because no payroll tax applies. Once the wage bill crosses the line, every additional salary carries the tax, so the marginal cost of the next hire steps up.
That step matters most exactly when a business is scaling its marketing team. The eleventh hire can be meaningfully more expensive than the headline salary, and a model that ignores payroll tax will keep recommending in-house headcount past the point where it stops being the cheap option.
Payroll tax is the on-cost that turns your tenth hire into a more expensive decision than your first.
How it shows up
Payroll tax shows up as a step in the marginal cost of hiring once the wage bill crosses the state threshold. The practical move is to load every acquisition-team salary with super, leave and payroll tax at your state's rate, so the true cost of the next marketer is visible before you commit to the role.
The Australian context
Payroll tax is distinctly Australian in this form, levied by the states and territories with different thresholds and rates in each. It does not exist as a single national tax, and it has no clean United States equivalent. For businesses employing across multiple states, or comparing the cost of teams in different locations, the variation is real and worth modelling rather than assuming a single rate.

Common questions
What is payroll tax?
A state and territory tax on the total wages a business pays, once that wage bill crosses a threshold. Each state sets its own threshold and rate, and it applies to wages above the line. It is separate from federal taxes like income tax and GST.
Why does payroll tax matter for marketing teams?
It is an on-cost that makes growing an in-house team more expensive than salaries suggest. Once your wage bill passes the threshold, every additional marketing salary attracts the tax, stepping up the cost of the next hire.
Does payroll tax vary across Australia?
Yes. Thresholds and rates differ between states and territories, so the same team can attract different payroll tax depending on where people are employed. A multi-state team needs more than a single assumed rate.
Can I avoid payroll tax by splitting my business?
No. Wages are grouped across related entities, so dividing a business into parts does not keep each under the threshold. The grouping rules combine the wage bills, which is designed to prevent exactly that.
