How do claims-made coverage, retroactive dates and extended reporting periods work?

By Mark Melliand, owner, Melliand Insurance Agency · 13 years as an independent agent · Published October 26, 2026

The short answer: Under many professional liability policies, whether a claim falls within coverage can depend on several dates and conditions, not just whether a policy was in force when the work was done. The policy’s wording decides which dates matter and how.

The dates that often matter:

When the alleged act, error or omission occurred
When a claim was first made against an insured
When notice was given to the insurer
The policy period
Any retroactive date
Any extended reporting period that applies

For what professional liability may cover, see our guide to what professional liability insurance covers.

Key terms

Term	What it means	What to check
Claim	Defined by the policy, and it can mean more than a lawsuit. One sample form includes a written demand for money or non-monetary relief, and a request to toll a statute of limitations or to mediate or arbitrate.	The policy’s definition of “claim,” and when a claim is considered “first made”
Policy period	The dates the policy is in force, shown on the declarations	Start and end dates, and any change at renewal
Claims-made	Coverage generally turns on when a claim is first made against an insured, subject to the policy’s other terms	The coverage grant and any reporting requirement
Claims-made-and-reported	A claim generally must be both made against the insured and reported to the insurer within the policy period, or within any window the policy allows	Reporting deadlines, including any period after expiration
Retroactive date	A date before which wrongful acts may be excluded, even if the claim is made during the policy period; many, but not all, claims-made policies have one	The date on the declarations, and whether it differs from the effective date
Prior acts coverage	Coverage for claims made during the policy period about acts before the policy began, when there’s no retroactive date or one earlier than inception	The retroactive date and prior-knowledge and prior-notice provisions
Notice of circumstances	A provision in some policies for reporting a situation that might lead to a later claim	Whether the policy has one, what details it requires, and when
Post-expiration reporting allowance	Extra time after the policy ends to report a claim that was already made during the policy period. It doesn’t, by itself, allow new claims to be first made after the policy ends.	Which claims qualify and the deadline
Extended reporting period (automatic or optional)	A period after the policy ends during which certain claims may be first made and reported. Some are automatic; others must be elected and paid for.	Whether new claims can be first made during it, its length, election and payment deadlines, eligible acts and available limits
Prior knowledge and related claims	Provisions that may limit coverage for matters known before the policy began, or treat related claims as one claim	The exact wording in each policy

Claims-made vs. claims-made-and-reported

Many professional liability policies are written on a claims-made basis. Labels vary, and insurers don’t all use them identically. The actual coverage grant and reporting conditions control.

Under a claims-made-and-reported form, a claim generally must be made against an insured and reported to the insurer during the policy period, or within any window the policy allows (IRMI). One sample form requires that the claim be first made against the insured and reported to the insurer during the policy period (Berkshire Hathaway Specialty sample form, illustrative).
Some policies describe themselves as claims-made but still contain reporting conditions that matter. Read both the coverage grant and the conditions.

By comparison, an occurrence policy generally responds to incidents that happen during the policy period, regardless of when the claim is filed (Texas Department of Insurance). It’s a different structure, with its own terms.

Retroactive dates and prior acts

What it may do. A retroactive date can exclude claims arising from wrongful acts committed before that date, even if the claim is made during the policy period (IRMI). Both sample forms reviewed limit coverage to wrongful acts on or after the retroactive date (Berkshire Hathaway Specialty sample form, illustrative; Hiscox sample form, illustrative).
It may differ from the effective date. A policy can start on one date and carry a retroactive date that is earlier, the same, or absent. Check the declarations.
Why an earlier date can matter. If you change insurers and the new policy’s retroactive date is later than your old one, work done in between may fall outside the new policy. Prior acts coverage depends on a retroactive date that is absent or earlier than the policy’s start (IRMI).
A matching date isn’t a guarantee. Prior-knowledge, prior-notice, related-claims, pending-claim and other provisions can still affect coverage for earlier work. For example, one sample form excludes wrongful acts the insured knew of before the policy period and had a reasonable basis to believe could give rise to a claim, and matters already the subject of notice under a policy it renews or replaces (Hiscox sample form, illustrative).

A new policy doesn’t automatically cover all earlier work.

Extended reporting periods (“tail” coverage)

Check whether a provision allows a claim to be first made after the policy ends, extends only the deadline for reporting a claim already made, or does both. These are different protections. A post-expiration reporting deadline should not automatically be treated as tail coverage for new claims.

An extended reporting period generally concerns eligible claims made and reported for a specified time after a claims-made policy ends (IRMI). It’s generally an endorsement to the last policy term, not a new policy (Utica National, general guidance). How it works varies by policy.

Automatic or basic provisions. Some policies include a short period at no added premium, often after cancellation or nonrenewal (IRMI). Not every policy has one, and some apply only in specific situations.
Optional or purchased extended reporting periods. Many policies offer a longer period for an added premium, with a limited time to elect it (Utica National, general guidance).
Prior acts coverage under a replacement policy. This is different: the new policy itself responds to claims about earlier work, subject to its retroactive date and other terms.

An extended reporting period generally doesn’t cover new work performed after the policy ends. In both sample forms reviewed, the wrongful act must have occurred before the policy ended (Berkshire Hathaway Specialty sample form, illustrative; Hiscox sample form, illustrative).

How two sample forms differ

These are examples from those specimen editions, not current product offerings or terms available to any particular business. They show how much terms can vary.

Provision	Berkshire Hathaway Specialty specimen (2020 edition)	Hiscox specimen (2013 edition)
Reporting after expiration for claims made during the period	No separate post-expiration reporting allowance identified in the reviewed text	Notice allowed up to 60 days after the policy period, but only for claims made within the period’s last 60 days. This extends reporting only.
Automatic extended reporting period	60 days, at no additional premium, if an optional ERP isn’t purchased. Claims must be first made during the ERP.	None stated in the form
Optional extended reporting period	Claims first made during the ERP. Written notice of election within 60 days of the end of the policy period, “along with” full payment; no separate payment deadline is stated.	Three years. Claims first made and reported during the ERP. Notice of election and full payment must both be received within 30 days after cancellation or nonrenewal.
Eligible acts	On or after the retroactive date and before the end of the policy period	On or after the retroactive date and before cancellation or nonrenewal takes effect
Limits	The ERP doesn’t increase or reinstate limits	Only the expiring policy’s remaining limits
Other restrictions	Not available after cancellation for nonpayment; doesn’t apply to claims covered by subsequent insurance you buy	Not available after cancellation for nonpayment; potential claims can’t be reported during the optional ERP

(Berkshire Hathaway Specialty specimen; Hiscox specimen)

What to check

Whether a claim can be first made after the policy ends, or only reported later
When a claim must first be made, and when it must be reported
Which prior services or acts qualify
Election deadlines and payment deadlines, which may differ
Duration
Available limits, and whether they’re shared with claims under the expiring policy
Restrictions or conditions, such as cancellation for nonpayment or other insurance

Don’t assume every tail:

covers new work performed after the policy ends
provides a new set of limits
is available for every cancellation or nonrenewal
has the same duration, cost or purchase deadline
works the same way as prior-acts coverage

Switching, lapsing, closing, retiring or selling

A business can receive a claim after it stops providing services. Before changing anything, review the actual policies, options and circumstances. Don’t cancel a policy or buy a particular extended reporting option until you have.

Changing insurers. Will the new policy keep your current retroactive date? How do its prior-knowledge, prior-notice and related-claims provisions treat earlier matters? Have known claims and circumstances been reported under the current policy as it requires?
Letting a policy lapse. Does the policy have an automatic period or post-expiration reporting allowance, and what does each actually permit? What optional extended reporting options exist, and what are the election and payment deadlines?
Closing the business or retiring. Who could still bring a claim about past work? What extended reporting options exist, for how long, and with what limits?
Selling or merging. Transaction terms and any change-of-control provisions in the policy require review. Who will be responsible for claims about work before the transaction, and which policy or endorsement is intended to respond?

Reporting claims, reporting circumstances and disclosing on an application

These are different things:

Reporting a claim. Notice to your insurer under the policy’s conditions. One sample form requires notice as soon as practicable, with copies of demands and legal papers (Berkshire Hathaway Specialty sample form, illustrative).
Reporting a circumstance. Some policies let you report a situation that might lead to a later claim (IRMI). If the policy’s circumstance-reporting requirements are satisfied, a later related claim may be treated as first made at an earlier time specified by the policy. Check the required information, deadlines and relationship between the reported circumstance and later claim (Berkshire Hathaway Specialty sample form, illustrative; Hiscox sample form, illustrative). Not every policy has this.
Disclosing on a new application. Telling a prospective insurer about a matter. It doesn’t take the place of notice under your existing policy.

Don’t assume telling an agent, requesting a quote or answering an application satisfies an existing policy’s notice requirements. Check the policy’s required recipient, method, information and deadlines. Seek prompt help if a claim or reportable circumstance may exist.

Three hypothetical examples

These examples are illustrations, not real clients. Each assumes a claims-made-and-reported policy, and the dates are invented. They show the questions raised, not whether a claim would be covered.

1. Earlier work, a later claim and a retroactive date

Assumptions: A consultant completes a project in June 2023. Her first professional liability policy runs January 1, 2024, to January 1, 2025, with a retroactive date of January 1, 2024. The client sends a written demand on October 15, 2024.
Questions raised: Does the retroactive date exclude acts before January 1, 2024? Did any of the work occur after that date? Is the demand a “claim” under the policy’s definition? Was it reported within the policy’s deadlines?

2. A change of insurers

Assumptions: An IT firm has annual policies with Insurer A from January 1, 2021, to January 1, 2026, each with a retroactive date of January 1, 2021. It buys a policy from Insurer B running January 1, 2026, to January 1, 2027. In November 2025, a client complains in writing about a 2024 project, without demanding money.
Questions raised: Does the complaint itself meet Insurer A’s definition of a claim, for example as a demand for non-monetary relief? If so, was it reported as Insurer A’s policy requires? If not, does Insurer A’s policy allow it to be reported as a circumstance, and were those requirements met in time? What retroactive date will Insurer B provide? How do Insurer B’s prior-knowledge and prior-notice provisions treat the complaint, and how was it answered on Insurer B’s application?

3. A claim after the business closes

Assumptions: A design firm’s policy runs January 1, 2025, to January 1, 2026, with a retroactive date of January 1, 2022. The firm stops operating, and the policy is not renewed. On May 12, 2026, a former client makes a written demand about 2024 work.
Questions raised: Does any automatic provision apply, and does it allow claims to be first made after the policy ends or only extend reporting? Was an optional extended reporting period offered, and was it elected and paid for by its deadlines? Does it permit a claim to be first made in May 2026, and was the claim reported on time? Does it cover acts after the retroactive date and before January 1, 2026? What limits remain?
