If you're issued with an assessment for unpaid RUC you must pay the amount owing within two months.

If you don't pay within two months, a 10% penalty will be applied. Another 10% will be applied if the amount is still unpaid after three months. 

Review of a RUC assessment

You can apply for a review of a RUC assessment if:

  • the assessment is incorrect, or
  • you, as the owner or operator of the RUC vehicle, were not the person responsible for the unpaid road user charges.

You must make an application for a review within 20 working days of the assessment date. You must include the reason for review, and any evidence you have to support that reason.
