Your CTP premium consists of the CTP Insurer Premium for the Policy of Insurance, the CTP Scheme Services fee that funds government services to support the Scheme, Stamp Duty and GST.
Several other compulsory fees and levies are collected at the same time as you renew your vehicle registration, which are the responsibility of other government agencies. Find out more about other fees and levies.
The CTP Regulator sets limits for each premium class so that premiums are sufficient to meet the cost of CTP injury claims and there is fairness in how motor vehicle owners fund the Scheme. These limits can be reset should conditions change, such as if the number of claims or the cost of claims change (see more information about how premiums are set).
CTP Insurers set their own premiums for each premium class based on how they assess the cost of the Scheme. Premiums are only accepted by the Regulator if they fall at or within the premium range.
The CTP Insurers can adjust their premiums at any time within the premium range. A new premium comes into effect two months after the Regulator approves it. This means any change will not impact the premium shown on your renewal notice or in your mySA GOV account. If you renew your registration (for a vehicle in the same premium class) at different times of the year, your premium may differ for this reason.
