What Is Payroll Tax?

Payroll tax is a state-based tax that businesses pay on the wages they pay to their employees. Unlike income tax, which employees pay on their earnings, payroll tax is an expense that employers must budget for once their total wages exceed certain thresholds. Each Australian state and territory administers its own payroll tax system with different rates and thresholds.

The tax applies to various forms of employee compensation, not just regular wages. This includes salaries, bonuses, commissions, allowances, superannuation contributions above the statutory minimum, fringe benefits, and, in some cases, contractor payments. Understanding what counts as taxable wages is essential for accurate calculations.

State-by-State Thresholds and Rates for 2026

Each state sets its own annual threshold and tax rate, making it important to know your specific obligations based on where your business operates.

Eastern States

New South Wales has an annual threshold of $1.2 million with a tax rate of 5.45%. Victoria's threshold is $700,000, with rates starting at 4.85%. Queensland maintains a threshold of $1.3 million and a rate of 4.75%. These variations mean businesses operating across multiple states need to track obligations separately for each location.

Other States and Territories

South Australia has a threshold of $1.5 million with a 4.95% rate. Western Australia also uses a $1.5 million threshold with rates beginning at 5.5%. Tasmania sets its threshold at $1.25 million with a 4% rate, while the Australian Capital Territory sets its threshold at $2 million with a 6.85% rate. The Northern Territory maintains a threshold of $1.5 million with a 5.5% rate.

How Payroll Tax Is Calculated

The calculation starts with your total Australian wages for the year. If your total wages exceed your state's threshold, you only pay tax on the amount above that threshold. For example, if your business in Victoria pays $900,000 in annual wages, you'd only pay payroll tax on $200,000 (the amount exceeding the $700,000 threshold).

Most businesses pay monthly, with returns due by the 7th or 21st day of the following month, depending on your state. The calculation includes wages from all employees across all business locations within that state. Businesses operating in multiple states must calculate and pay tax separately for each jurisdiction.

Managing Your Payroll Tax Obligations

Keeping accurate records is fundamental to managing payroll tax effectively. Track all employee payments, including regular wages, overtime, bonuses, and benefits throughout the year. This documentation helps you monitor when you're approaching thresholds and ensures accurate reporting.

Register for payroll tax before you reach the threshold. Most states require registration within seven days of exceeding the threshold amount. Early registration prevents penalties and gives you time to understand the reporting requirements. Online payroll services can automate threshold monitoring and alert you when registration becomes necessary.

Consider using automated systems that calculate payroll tax obligations as part of your regular payroll processing. These tools track cumulative wages, apply correct rates, and generate required reports, reducing the risk of errors and missed payments.

Common Mistakes to Avoid

Don't assume you're exempt because you're just over the threshold. Even exceeding the limit by a small amount creates tax obligations. Monitor your wages throughout the year rather than waiting until year-end to assess your situation.

Avoid misclassifying workers as contractors to reduce your taxable wages. Tax authorities scrutinise contractor arrangements, and incorrect classifications can result in back payments and penalties. Understand the difference between genuine contractors and employees for payroll tax purposes.

Remember that wages paid across all your related businesses count toward the threshold. Businesses with the same ownership or control must group their wages when calculating payroll tax liability. This grouping provision catches many business owners by surprise.

Payroll tax represents a significant obligation for growing Australian businesses, with varying thresholds and rates across different states.
