Retroactive Date
The retroactive date on a claims-made policy defines how far back in time covered incidents can originate — incidents before this date are excluded.

Definition
The retroactive date is a provision in claims-made liability policies that sets the earliest date from which covered incidents can arise. If a policy has a retroactive date of March 1, 2022, any claim based on an incident that occurred before that date will be denied, regardless of when the claim is filed. When a professional first purchases a claims-made policy, the retroactive date is typically set to the inception date of coverage, providing no prior acts protection. Over years of continuous coverage with the same insurer, the retroactive date remains fixed while the policy renews, gradually expanding the window of covered incidents. Switching insurers is the most common trigger for retroactive date problems — the new insurer will want to set today's date as the new retroactive date unless the business specifically negotiates prior acts (nose) coverage or purchases tail coverage from the departing insurer. A retroactive date gap — even a single day — can create an uncovered period for professional liability claims, making continuity of coverage one of the highest priorities when managing claims-made policies.
