Essential guide to professional indemnity cost for CPA Australia public practitioners

If you are a CPA or FCPA accountant in Australia, professional indemnity insurance is not just nice to have. It is a core requirement that sits alongside your Public Practice Certificate obligations and quality controls. This guide explains basic rules, the cover features to look for, and the practical choices that tend to influence price.

At a glance

  • CPA Australia requires public practitioners to hold professional indemnity insurance that meets specific minimum features.
  • The policy wording matters. Small differences in limits, costs inclusions, retroactive dates and reinstatements can change how protected you are.
  • Premiums vary. Insurers generally rate on factors like services offered, annual gross fees of your business, claims history and controls.

Who this is for

  • CPA and FCPA members

    CPA and FCPA members who plan to provide public accounting services including, but not limited to accounts preparation bookkeeping, BAS and tax preparation, insolvency, valuations, management consulting or financial reporting.

Which factors determine costs (premiums) for CPA Australia public practitioners?

Your premium (or cost you pay for your insurance) is based on various factors, depending on the insurance provider, the market conditions and economic environment, as well as your specific circumstances. Here are some examples:

  • Your coverage limits – the higher the coverage, the more you will pay. Keep this in mind if you need a certain level of cover, but an insurer is offering a lower premium.
  • Services offered and activities you perform.
  • Gross fee income and projected growth
  • Your claims history – how many claims have you made in the past?
  • Your professional experience – the number of years you’ve been practicing. Your years of experience and track record will affect your premium.
  • The firm size and structure – larger businesses naturally face higher risk.
  • The nature of your business – the breadth and type of services you offer can influence your premium. For example, company auditing carries higher risks and, in some cases, it is excluded as cover for larger organisations and publicly listed companies.
  • Your location: Where you work from and what external risks and regulations you’re exposed to.

What you need to know when choosing professional indemnity solution

Retroactive date

A retroactive date defines how far back in time a loss can occur for your policy to cover your claim. If a claim happens prior to your retroactive date, your policy won't provide benefits. It is a feature of the “claims-made” Professional Indemnity insurance.

  • Example – You performed a service in June 2019. In August 2021, you have been notified of a potential loss for the work you performed in 2019. You purchased a new Professional Indemnity policy, and your retroactive date is the inception date of the policy on 1 February 2021. The incident that you have been notified of in August 2021 that occurred in 2019, will not be covered by your current policy, as your retroactive date only covers claims dating back to 1 February 2021, and not any further back.
  • Tip – pay attention to the retroactive date, and whether the retroactive date is Unlimited.

Claims made

Claims made coverage protects you for claims filed against you during the current insurance period, regardless of when the incident occurred, provided there is no retroactive date limit. When you (the insured) are first notified of a potential claim or incident, it is the current policy that the claim/incident will fall under. 

  • Example – You performed a service for a fee in June 2019. In August 2021 you have been notified of a potential loss for the work you performed in 2019. The claim will fall under the 2021 policy not the 2019 policy, as that is when the claim was made. The current insurer will respond to a claim made against the insured, and not the insurer at the time of the original incident.
  • Tip – inform the current insurer of any potential claims during the policy period.

Inclusive vs costs exclusive limit

Policies that are costs inclusive can erode your limit during defense. Costs exclusive limits pay defense costs over and above the limit and may better protect the sum available to meet damages.

  • “Inclusive” limit, means the Defence Costs are included in the limit.
  • “Exclusive” limit, means the Defence Costs are excluded from the limit.
  • Example – Professional Indemnity Limit: $1,000,000 inclusive of costs.
    You have a limit of $1,000,000 which includes the Defence costs.
    The defence costs will erode your limit. “Inclusive” = included. Professional Indemnity Limit: $1,000,000 exclusive of costs.
    You have a limit of $1,000,000, the Defence costs are in addition to the limit.
    The defence costs payable will not erode the limit. “Exclusive” = excluded.
  • Tip – An Exclusive limit will not be eroded by Defence Costs.

Exclusive vs inclusive excess

Inclusive excess means the insured must pay the amount of the excess towards the legal and defence costs upfront.

Costs exclusive excess means the insured does not pay any excess towards the legal and defence costs but only pays the amount of the excess towards the settlement of any claim.

  • Tip - Exclusive excess will reduce any excess paying towards legal and defence costs.

Extensions and sub-limits

Look for appropriate sub-limits for items such as inquiry costs, loss of documents, libel and slander, fraud and dishonesty, fidelity, outgoing and incoming principals.

Do I need a run-off cover

Professional indemnity policies are written on a ‘claims made’ basis. This means that the policy will only respond to claims, which are made against an insured and notified to the insurer during a current policy period, irrespective of when the work was performed by the insured. If the policy has expired, lapsed or cancelled, no additional claims can be made under the policy, as it is not current.

There is a potential for claims to be made against an insured after a business is wound up, has ceased trading or you are retiring. If a claim is made at a time in the future and there is no insurance policy in place, there would be no protection for the insured.

A run-off insurance policy can be purchased prior to cessation of the business. It will provide coverage to an insured for future claims made against them which arise from acts, errors or omissions which occurred prior to the inception of the run-off policy. Run-off policies can be purchased on an annual basis, or a multi-year basis with one upfront premium payment.

  • Tip – A run-off policy can protect you for your past work, when you or your company have ceased trading.

Automatic reinstatement clause and limit of indemnity

The limit of indemnity is the maximum amount payable under a policy during a policy period. Some policies may include an automatic reinstatement clause, which restores the limit of indemnity after it has been exhausted by a claim or series of claims, allowing coverage for multiple unrelated claims that together exceed the original limit. However, no single claim payment will exceed the stated limit of indemnity.

Vicarious Liability

Vicarious liability refers to a situation where someone is held responsible for the actions or omissions of another person. A principal or you the insured can be considered vicariously liable for the actions of your contractors/sub-contractors under your supervision or direction.

In other words, you, the insured, can be sued for the actions or mistakes of your contractors, you can be vicariously liable.

  • Tip – make sure all your contractors and sub-contractors have their own current Professional Indemnity, Public Liability insurance and other relevant insurances.

How to choose and buy indemnity cover

  1. Work with a broker who understands CPA practice. Your broker should know CPA Australia’s minimum requirements and the nuances of accounting firm risks and be able to advice.
  2. Check the policy against the By-Law expectations. Confirm retroactive date, reinstatements, scope of services, and treatment of costs and excess. 
  3. Accurately match your services to a policy wording. A professional services description is an important component of professional indemnity cover. Consider annual fee size, service profile, activities you are undertaking, contractual obligations and Professional Standards Legislation settings in your state or territory. 
  4. Keep notifications timely. On a claims made policy, early notification protects your position. Document notifications so potential claims are reported within the policy period.

Frequently asked questions

Your policy responds to claims made and circumstances notified during the policy period. If you become aware of a matter that may lead to a claim, notify your insurer within the period. The underlying act can have occurred earlier if it is within the retroactive cover.

The retroactive date is the earliest date from which your past work is covered. CPA Australia guidance expects a retroactive date no later than seven years before the policy period begins unless the policy provides unlimited retroactive cover.

PI policies aggregate claims to the limit for the policy period. Automatic reinstatements refresh the limit after a claim, which helps if there is more than one matter in the year.

If defence costs are included within the limit, every dollar spent on investigation and defence reduces the amount left to pay damages and claimant costs. Costs exclusive limits pay defence costs in addition to the limit.

With a costs inclusive excess you may pay the excess even if no settlement is paid. With a costs exclusive excess the excess typically applies only when a settlement or judgment is paid.

Accounting, bookkeeping, taxation, auditing and assurance, insolvency and corporate reconstruction, management accounting and consulting, financial planning or advice, forensic accounting, credit services, valuations, transactional accounting and financial reporting are within the definition of public accounting services. Always confirm your exact scope with your broker and policy wording.

Mergers and acquisitions need to be disclosed. Policies may require notice within a set period. Additional premium may apply to extend cover to the new entity or past work.

Any fact, situation or circumstance which a reasonable person in your position would consider may result in a claim. When in doubt, speak with your broker and consider notifying.

There is no one size fits all. Consider contract requirements, fee size, service types, client profile, Professional Standards Legislation and your risk appetite. Your broker can model options.
