    Payroll Tax

    Payroll tax is a general purpose tax assessed on the wages paid by an employer in Western Australia.

    The tax is self-assessed - the employer calculates the liability and pays the appropriate amount to the Office of State Revenue by way of a monthly, quarterly or annual return.

    On 8 December 2004 new legislation was passed making it mandatory for an employer that has, or is a member of a group that has, an expected payroll tax liability equal to or greater than $100,000 per annum, to lodge and pay their payroll tax return via Revenue Online (ROL). This amendment to the Pay-roll Tax Assessment Act 2002 was effective 1 July 2006.

    Pay-roll Tax Exemption For Wages Paid To Employees With A Disability

    As announced in the May 2012 State Budget, wages paid to some employees with a disability are now exempt from pay-roll tax.

    This exemption applies to businesses that pay wages to new employees with a disability who commenced employment on or after 1 July 2012, for whom the employer received or was entitled to receive a wages subsidy under the Commonwealth Government's Disability Employment Services program, or where the employee is eligible for any form of support from the Western Australian Disability Services Commission.

    More detailed information is provided in Wages Definition Fact Sheet.

    Harmonisation Protocol

    In 2007 Commissioners from all States and Territories signed a protocol confirming their commitment to the harmonisation of payroll tax administration including consistency of rulings.

    The Pay-roll Tax Assessment Amendment Act 2010 amended the Pay-roll Tax Assessment Act 2002 with effect from 1 July 2009 to harmonise the legislation of Western Australia's payroll tax system with the legislation of other jurisdictions.
