About payroll tax

Payroll tax is assessed on the wages paid by an employer in Western Australia and the Indian Ocean Territories.

Payroll tax is a self assessed tax meaning that the onus is on you, as an employer, to ensure that any information you provide is correct and that you comply with your tax obligations. Payroll tax is paid into the Consolidated Fund of Western Australia to meet the costs of public services such as education, health, public safety, and law and order.

Register through Online Payroll Tax (Revenue Online) if the total Australian taxable wages paid by you or your group exceed the monthly or annual threshold amount. While your total Australian taxable wages are used to determine whether you are liable and the rate of tax applicable, you only pay tax on wages paid or payable in Western Australia or the Indian Ocean Territories (IOT).

If you don't register and lodge your returns as required, we may

Once you have registered for payroll tax, you will be advised of your registration details and your lodgment frequency - either monthly, quarterly or annually.

  • Monthly returns are due and payable by the 7th of the following month in which the taxable wages were paid or payable. The June return is due and payable by 21 July.
  • Quarterly returns are due and payable by 7th October, January and April and 21 July.
  • Annual returns are due and payable by 21 July.

As part of the annual reconciliation process, we calculate your annual liability to see if you have paid the right amount of tax.

A payroll tax liability may exist if you pay wages in the Indian Ocean Territories of Cocos and Christmas Islands as if they were Western Australia. See details of the arrangement between Western Australia and the Commonwealth.

Rates and thresholds

From 1 July 2018 to 30 June 2023, payroll tax is calculated on a tiered rate scale that gradually increases the tax rate to a maximum of 6.5% for employers, or groups of employers, with annual taxable wages in Australia of more than $100 million. See information about calculating your payroll tax or use our payroll tax calculator.

Changes to the threshold amount

From 1 July 2019 to 30 June 2020, tax will be calculated separately for each six-month period (half-year) using the following thresholds:

Period Annual
Threshold
Half-year Taxable Threshold Half-year Upper Threshold
1 July - 31 December 2019 $850,000 $425,000 $3,750,000
1 January - 30 June 2020 $950,000 $475,000 $3,750,000

The annual liability will be the sum of the liability for each half-year in the assessment year.

For example, an employer pays monthly wages of $75,000 ($900,000 per annum).

  • For July – December 2019, the total wages of $450,000 exceed the taxable threshold of $425,000. Payroll tax of $1,551 is paid during this period.
  • For January – June 2020, the total wages of $450,000 are below the taxable threshold of $475,000. There is no payroll tax liability for this period.
  • Without the threshold increase, payroll tax of $3,102 would have been paid during 2019-20.
  • Based on the 2019-20 wages, the employer will not be liable for payroll tax in 2020-21.

See Circular 12 for more information.

Currently, the tax-free threshold gradually phases out for employers or groups of employers with annual taxable wages in Australia between $850,000 and $7.5 million. See videos about the diminishing tax-free threshold.

Calculation for the diminishing threshold

A tapering value formula is used to calculate the gradual reduction in the deductable amount which employers may claim against their WA taxable wages between the annual threshold amount of $850,000 and the upper threshold amount of $7,500,000.

During 2019-20 and 2020-21, there will be a separate tapering value for each half-year period based on the half-year taxable and upper thresholds shown above.

TV = AT / (UT - AT or $850,000 / ($7,500,000 - $850,000)

Where

  • TV is the tapering value
  • AT is the annual threshold amount for the year
  • UT is the upper threshold amount

This can be simplified to 17/133.

This means the threshold amount will reduce by $17 for every $133 of wages over the threshold.

The deductable amount is equal to AT - [(Wages - AT) X TV]

For example, for annual wages of $900,000, the deductable amount (threshold) would be
$850,000 - [($900,000 - $850,000) X (17/133)] = $843,609
