How is future loss of earnings proved in a NSW CTP claim?

The Act separates statutory benefits from common-law damages. PAWE is an earnings benchmark used in the statutory weekly-payment system. Future economic loss is a possible head of damages for lost earnings or impaired earning capacity under Part 4. A claimant does not obtain damages merely because weekly benefits were paid or because PAWE was accepted.

Damages eligibility has separate requirements, including the injury and fault provisions that apply to the claim. Section 4.4 prevents an award of damages where the claimant’s only accident injuries are threshold injuries. Greater than 10% WPI is a separate test that matters specifically to non-economic loss; it is not a universal threshold for economic-loss damages.

Section 4.5 limits economic-loss damages mainly to past or future loss of earnings and deprivation or impairment of earning capacity. Section 4.7 then requires the court or Personal Injury Commission to be satisfied that the assumptions used for future loss accord with the claimant’s most likely future circumstances but for the injury. The resulting amount is adjusted for the percentage possibility that those events might not have occurred.

This is why the assessment has two sides. The “but-for” side asks what work, hours, progression and earnings were most likely without the accident. The injured side asks what work the person can probably do now and in the future. Section 4.8 permits a dispute about the degree of impairment of earning capacity to be referred for medical assessment, but the damages decision also requires non-medical evidence about the labour market and the claimant’s actual circumstances.

The strongest claim usually joins contemporaneous records rather than relying on a single prediction. Medical evidence should identify diagnosis, causation, prognosis, restrictions, treatment and likely capacity. Employment evidence should show the pre-accident trajectory, duties, hours, remuneration and realistic opportunities. Post-accident work attempts are important because they can show both retained capacity and the practical limits of maintaining work.

A vocational report may help where the pre-injury occupation is no longer suitable, but it should use accurate medical restrictions and actual qualifications. Accountant evidence may be needed for a business owner. Assertions about promotion, overtime or a new career need supporting material; equally, an insurer should not assume that current temporary work proves secure long-term capacity.

• Employment contracts, payslips, tax records, rosters and superannuation records.
• Employer statements about duties, progression, overtime and available suitable work.
• Treating and independent medical reports addressing capacity and prognosis.
• Certificates of Fitness and a chronology of return-to-work attempts and absences.
• Qualifications, licences, training records, job applications and vocational assessments.
• Business accounts and accountant working papers for self-employed claimants.
• Evidence of post-accident earnings and why hours, duties or jobs changed.

Start by defining the two competing employment futures in plain terms. Then identify each factual assumption, the document that supports it and the uncertainty that remains. This produces a transparent schedule that can be tested, rather than a large figure built from hidden assumptions.

If the insurer disputes capacity, separate the medical question from the arithmetic. If it disputes likely earnings, obtain the employment or accounting material. If it disputes causation, make sure the medical history explains why the present restriction is related to the motor accident rather than a pre-existing condition or later event.

• Confirm that a common-law damages claim is legally available and has been lodged correctly.
• Build a pre-accident employment and earnings chronology.
• Record post-accident work attempts, accommodations, absences and earnings.
• Obtain a current prognosis and functional-capacity opinion.
• State the proposed but-for and injured-future assumptions separately.
• Apply contingencies and statutory limits only after the factual model is clear.
• Reconcile the schedule with weekly benefits already paid and any insurer calculations.

Common mistakes include treating PAWE as the damages rate, assuming permanent symptoms prove permanent earnings loss, ignoring residual capacity, annualising occasional overtime without evidence and using an arbitrary retirement age. A diagnosis can explain restrictions, but it does not by itself prove the job that would have been held or the amount that would have been earned.

Where exact weekly loss cannot responsibly be projected, parties sometimes argue for an evidence-based “buffer” for lost opportunity or labour-market disadvantage. A buffer is not an automatic fallback and should not conceal missing evidence. The factual basis, nature of the risk and competing possibilities still need to be explained.

SIRA states that a common-law damages claim generally must be made within three years of the motor accident, subject to the Act’s late-claim provisions. That is a claim requirement, not a rule that the claim must settle within three years. A settlement offer may also have a response date, while a PIC or court matter can have a separate timetable. Record each date separately.

Settling before prognosis, work trials or earnings evidence are sufficiently developed can undervalue future loss. The Act does not impose a general requirement that injuries reach “maximum medical improvement” before settlement, and PIC Procedural Direction MA3 confirms that a damages claim may settle at any time. The practical issue is whether uncertainty has been identified and valued. Last reviewed: 11 August 2026. This is general information only and does not determine damages eligibility or value in an individual claim.

A review can test the proposed work assumptions against the medical, employment and financial evidence, identify what remains unsupported and separate a damages issue from any continuing weekly-payment dispute.
