State payroll tax compliance in Australia
Payroll tax is a state and territory tax on Australian wages. Each jurisdiction has its own Payroll Tax Act with different thresholds, rates, grouping rules and exemptions, but most states have harmonised core provisions. This guide covers the 10 core payroll tax obligations for Australian employers.
Coverage
Employers paying Australian wages above the state or territory threshold, alone or within a group. Includes corporations, trusts, partnerships, government agencies and not-for-profits unless specifically exempt.
Legal basis
Payroll Tax Act 2007 (NSW), Payroll Tax Act 2007 (Vic), Payroll Tax Act 2007 (Tas), Payroll Tax Act 2008 (SA and NT variations), Payroll Tax Act 1971 (Qld), Pay-roll Tax Assessment Act 2002 (WA), Payroll Tax Act 2011 (ACT). Taxation Administration Acts in each jurisdiction.
The obligations
Register in each relevant state
Register with the revenue office of every state or territory in which taxable wages exceed the registration threshold, within the statutory timeframe after crossing it.
Apply the correct state threshold
Apply the tax-free threshold in each state (annually adjusted) on a pro-rata basis when wages are paid in more than one jurisdiction.
Pay at the correct state rate
Apply the rate, surcharges and mental-health levies (where applicable) for each state to Australian taxable wages paid in that jurisdiction.
Include wages, super and fringe benefits
Include salary and wages, super contributions, fringe benefits, termination payments, bonuses and allowances in the definition of taxable wages.
Apply the relevant contractor provisions
Include payments to relevant contractors in taxable wages unless a specific contractor exemption applies (e.g. 90-day rule, approved by Chief Commissioner).
Apply grouping rules correctly
Identify grouped entities based on common ownership, common control, shared employees or tracing provisions, and lodge a joint return where grouped.
Lodge monthly and annual returns
Lodge monthly returns by the 7th of the following month (dates vary) and an annual reconciliation by 21 July in most states.
Claim rebates and exemptions correctly
Claim available rebates — such as apprentice and trainee rebates, regional employer rebates and JobsPlus — only where the statutory criteria and record-keeping apply.
Keep five years of payroll tax records
Keep records supporting taxable wages, exemptions, grouping and interstate apportionment for at least five years in accordance with the applicable Taxation Administration Act.
Disclose errors voluntarily
Make voluntary disclosures to state revenue offices when errors are identified to reduce interest and penalty tax under the applicable Taxation Administration Act.
What happens if you do not comply
State Payroll Tax Acts impose interest and penalty tax of up to 75% of the shortfall under each Taxation Administration Act, plus prosecution for serious cases. Grouping breaches can also cascade across states as each jurisdiction reassesses the return.
Reporting requirements
Monthly returns and payments (dates vary by state), an annual reconciliation (typically 21 July), voluntary disclosures, and responses to state revenue office audits and data-matching enquiries.
What firms should do today
- Map each employee and contractor payment to the state in which it is taxable
- Keep a grouping map reviewed whenever ownership or control changes
- Align payroll, STP and payroll tax definitions of wages
- Track each state's rebate, surcharge and threshold changes annually
- Run an annual internal review before the 21 July reconciliation
