What Is a TPA in Insurance?

A TPA, or third-party administrator, handles insurance claims on behalf of someone else: an insurer, an underwriting agency or a self-insured organisation. It takes notice of loss, assesses and manages claims, makes decisions within its authority and arranges payments, while the client keeps the risk. In Australia, claims handling for insurers can need an AFS licence.

Key takeaways

A TPA is a claims business that works for the party carrying the risk, not for the claimant.
According to ASIC, handling and settling insurance claims has been a financial service needing an AFS licence since 1 January 2022.
CPS 230 requires insurers to treat claims management providers as material service providers by default, according to Norton Rose Fulbright.
According to Coverager, Australian TPA Quartz Claims chose Five Sigma in May 2026 as the core of its claims operation.
TPAs often run claims for many clients at once, so keeping each client's rules and reporting separate is their main operational challenge.

What is a TPA?

A TPA is a third-party administrator: a business that handles insurance claims for another organisation. It sits between the party carrying the risk and the claimant, doing the claims work under a contract and within the authority its client gives it. Its client, usually an insurer, agency or self-insurer, stays responsible for the outcome.

The "third party" is the TPA itself. The insurer or self-insurer is the first party to the arrangement, the claimant is the second, and the TPA is the third. That naming is why the term is used for administrators rather than for parties to the claim.

TPAs range widely in size. Some are global claims businesses; others are specialists in one line, such as workers' compensation or liability. What they share is the role: running claims they do not pay for themselves.

What do TPAs do in claims?

TPAs do the claims work their client would otherwise do: taking first notice of loss, setting up and investigating claims, appointing assessors and suppliers, deciding claims within delegated authority, arranging payments and reporting to the client. Some also handle recoveries, litigation management and complaints for the client.

Authority shapes the work. The contract sets what the TPA may decide alone and what it must refer back. Above a set amount, or in a disputed case, the client usually decides.

Reporting is part of the job. The client needs to see claim numbers, reserves, payments and service levels, often monthly. As a result, a TPA's systems matter to the client as much as to the TPA.

Who hires a TPA?

Insurers, underwriting agencies, self-insured organisations and captives hire TPAs. Insurers use them for specialist lines, overflow or catastrophe surges, and agencies when they lack an in-house claims team. Self-insurers, such as large employers and councils, use them to run claims they carry but do not want to staff.

The reasons are capacity and expertise. A TPA brings trained handlers and processes from day one. In addition, it can move staff to a surge, such as a storm, faster than a client could hire.

TPAs are active in Australia. According to Coverager, Quartz Claims, an Australian TPA serving insurers and MGAs across Australia and New Zealand, selected Five Sigma's platform in May 2026. The in-house or outsourced claims covers when hiring a TPA makes sense.

How are TPAs regulated in Australia?

In Australia, TPAs that handle claims for insurers can need an AFS licence, because claims handling and settling is a financial service. Insurers that use TPAs must also manage them as material service providers under APRA's CPS 230. The General Insurance Code of Practice binds service suppliers that handle claims for subscribing insurers.

Licensing came first. According to ASIC, handling and settling insurance claims has been a financial service needing an AFS licence since 1 January 2022, and its guidance explains when claims managers acting for insurers need one. The ASIC claims handling guide covers the detail.

Insurer oversight adds to it. According to Norton Rose Fulbright, CPS 230 requires insurers to classify claims management providers as material service providers at a minimum, unless they can justify otherwise. That brings due diligence, contract terms and monitoring to every TPA arrangement.

What software do TPAs use?

TPAs use claims management platforms that can run claims for several clients at once. Each client's rules, authority limits, workflows and reporting stay separate. They also need payments, audit trails and strong permissions, because client data must not mix. Some use the client's own system instead of theirs.

Multi-client control is the core need. A TPA may run one process for an insurer's motor claims and a different one for a council's liability claims, often on the same day. A platform where those processes can be configured without developers makes that easier.

ClaimsGateway (claimsgateway.com) is one such platform, serving TPAs among other segments, with workflows configured by the business. The ClaimsGateway TPA page describes its approach.

Other platforms take different approaches. The TPA claims software list compares them.

Frequently asked questions

What does TPA stand for in insurance?

TPA stands for third-party administrator. It is a business that handles insurance claims on behalf of another organisation, such as an insurer, underwriting agency or self-insured organisation. The TPA does the claims work under a contract, while the organisation that hired it keeps the risk and the responsibility for outcomes.

What is the difference between a TPA and an insurer?

An insurer carries the risk and pays claims from its own capital. A TPA carries no risk: it handles claims on behalf of the insurer or self-insurer that hired it, within the authority it has been given. The insurer remains accountable for the claims a TPA handles in its name.

Do TPAs need an AFSL?

Often, yes. Since 1 January 2022, handling and settling insurance claims has been a financial service in Australia, so a TPA handling claims for an insurer may need an AFS licence or authorisation. ASIC's guidance explains when the requirement applies. TPAs should take advice on their own position.

What software do TPAs use?

TPAs use claims management platforms that can run claims for several clients at once, keeping each client's rules, authority and reporting separate. They need payments, audit trails and permissions too. Some TPAs work in their client's own claims system instead. Platforms such as ClaimsGateway serve TPAs among other segments.

Can a TPA handle claims for several insurers?

Yes. Many TPAs handle claims for several insurers, agencies and self-insurers at once, each under its own contract, authority and service levels. Keeping those clients' data, rules and reporting separate is a core requirement, which is why multi-client controls matter in a TPA's claims system.
