Certificate of Fitness vs Certificate of Capacity
Two different certificates for two different claim types. This guide explains the differences and when each applies.
In This Guide
Certificate of Capacity (WorkCover)
The Certificate of Capacity is used exclusively in the NSW workers compensation system. It is issued under the Workers Compensation Act 1987 and uses the SIRA-prescribed template. It documents your work injury, diagnosis, capacity for work, restrictions, treatment plan, and return-to-work recommendations. It is sent to you, your employer, and your WorkCover insurer.
Certificate of Fitness (CTP)
The Certificate of Fitness is used in the NSW CTP (motor vehicle accident) system. It is issued under the Motor Accident Injuries Act 2017. It documents your accident injuries, fitness for work, and treatment recommendations. The maximum review period is 28 days. It is provided to you and your CTP insurer.
Key Differences
| Feature | Certificate of Capacity | Certificate of Fitness |
|---|---|---|
| Claim type | WorkCover (workers comp) | CTP (motor vehicle) |
| Legislation | Workers Compensation Act 1987 | Motor Accident Injuries Act 2017 |
| Max review period | Set by doctor (typically 2–4 weeks) | 28 days maximum |
| Separate certificate fee | Yes — WCO001 ($56.20 + GST once per claim) | No — included in consultation fee |
| Billing rates | SIRA-gazetted rates | AMA rates |
| Sent to employer | Yes (mandatory) | Not mandatory |
Why It Matters
Using the wrong certificate for your claim type will result in rejection by your insurer. If you were injured at work, you need a Certificate of Capacity. If you were injured in a motor vehicle accident, you need a Certificate of Fitness. Claims Doctor issues the correct certificate for your claim type, using the current SIRA template.
