Understanding Late Payment Interest in NSW CTP Claims
If a CTP insurer in New South Wales fails to pay statutory benefits on time, injured people may be entitled to penalty interest under the Motor Accident Injuries Act 2017. This interest is not a discretionary payment but a legally mandated right when payments are delayed beyond the due date. Injured individuals in Greater Sydney often ask how this interest is calculated, when it applies, and what they can do if it is not paid. The answer lies in the statutory framework that governs CTP claims and the obligations placed on insurers to pay benefits promptly.
Legal Basis for Late Payment Interest
Late payment interest arises under the Motor Accident Injuries Act 2017, which sets out the rights and obligations of claimants and insurers. The Act provides that if a CTP insurer fails to pay a benefit within 14 days of the due date, interest must be paid on the overdue amount from the date the payment was due. The rate of interest is set at 10% per annum, as specified in the Motor Accident Injuries Regulation 2017. This is not a discretionary or negotiated rate but a fixed statutory entitlement.
The entitlement to interest applies to all statutory benefits, including weekly income payments, treatment and care benefits, and lump sum payments for permanent impairment. It does not apply to common law damages, which are assessed separately and subject to different rules. The interest is calculated on the unpaid amount from the due date until the date of actual payment, and it must be paid in addition to the original benefit.
What Injured People in Greater Sydney Should Know
Injured people in Greater Sydney should be aware that the insurer’s failure to pay on time does not require a claimant to take legal action to obtain interest. The right to interest arises automatically under the Act. However, the insurer must still acknowledge and process the claim for benefits to be considered due. Delays in processing or issuing payments may still trigger the interest obligation.
The most common sources of delay include administrative errors, failure to verify medical evidence in a timely manner, or disputes over the claimant’s eligibility for a benefit. If an insurer disputes a claim, they must notify the claimant in writing and provide a reason for the dispute. A dispute does not automatically suspend the payment obligation or prevent interest from accruing on amounts that were due but not paid.
Practical Steps and Evidence
To establish a claim for late payment interest, injured people should preserve all documentation related to the payment timeline. This includes:
- Copies of correspondence with the insurer, including emails and letters.
- Payment schedules or benefit approval letters.
- Records of when payments were received, including bank statements.
- Medical reports and treatment plans that support the claim for benefits.
Photographs of accident scenes, witness contact details, and police reports may also help establish the timeline of events and the insurer’s response. These records are not required to claim interest but may be useful if a dispute arises.
Time Limits and Dispute Resolution
There is no time limit for claiming late payment interest under the Motor Accident Injuries Act 2017. The right to interest continues until the insurer pays the overdue amount. However, claims for benefits must be made within the statutory timeframes. For most claims, the initial claim must be made within three years of the accident. Failure to make a claim within this period may prevent the claimant from recovering any benefits, including interest.
If an insurer refuses to pay interest, the claimant may request a review through the insurer’s internal dispute resolution process. If the dispute remains unresolved, the claimant may refer the matter to the State Insurance Regulatory Authority (SIRA). SIRA has the authority to investigate and enforce compliance with the Act, including the payment of interest.
Hypothetical Example
A pedestrian in Sydney’s Inner West was injured in a motor vehicle accident on 15 March 2026. The CTP insurer approved weekly income payments on 10 April 2026, but the first payment was not made until 20 May 2026. The insurer failed to pay within 14 days of the due date. The claimant is entitled to interest on the overdue weekly payments at 10% per annum from 10 April 2026 until 20 May 2026. The insurer must pay this interest in addition to the original weekly payments.
When to Seek Advice
While the law on late payment interest is clear, the practical application can vary based on the insurer’s actions, the nature of the delay, and the claimant’s circumstances. Some claimants may not realise that interest is automatically payable or may not know how to calculate it. Others may face resistance from insurers who dispute the entitlement. In such cases, independent legal advice may help clarify rights and ensure compliance.
