When insurance duty appliesHow insurance duty is calculated

Insurance duty is payable on general insurance policies.

General insurance applies to property in WA, or a risk, contingency or event concerning an act or omission that, in the normal course of events, may occur within WA.

Common general insurance policies cover motor vehicles, house and contents, travel insurance, non-life insurance etc.

Duty is calculated at a rate of 10% on the total premium for a policy. This is the consideration paid to an insurer, including any GST that applies.

Premiums can be apportioned between jurisdictions if more than one jurisdiction has nexus to the contract of insurance. 

See the fact sheet below which contains a schedule that details the basis upon which the premium paid or payable on policies of insurance is to be apportioned.
