Professional indemnity insurance may help protect businesses and professionals if a client claims their advice or services caused financial loss. It may include cover for legal defence costs and compensation, subject to policy terms.

It applies to any professional who provides advice or specialist services for a fee. A client can make a claim even if you acted correctly. Defending that claim costs money whether it succeeds or not.

What is professional indemnity insurance in Australia?

Professional indemnity insurance may help protect businesses and professionals if a client claims their advice or services caused financial loss. It may include cover for legal defence costs and any compensation awarded, subject to policy terms. It is often abbreviated to PI insurance and is designed for any professional who provides advice or specialist services for a fee.

What Does Professional Indemnity Insurance Cover?

PI insurance is designed to cover claims arising from professional services. The main categories:

• Negligence and errors. Claims that your professional work fell below the expected standard and caused financial loss.
• Omissions. Claims that advice or information was not provided when expected, causing the client a loss.
• Breach of confidentiality. Claims that confidential client information was disclosed or misused without authorisation.
• Misleading advice. Claims that inaccurate advice was relied on to the client's financial detriment.
• Intellectual property infringement. Claims that your work unintentionally used or replicated protected material.
• Defamation. Claims that statements made in providing your services caused reputational harm.
• Legal defence costs. May include cover for investigating, defending, and settling a claim, even where the claim has no merit, subject to policy terms.

PI does not cover physical injury or property damage. Those fall under public liability insurance. One incident can generate either type of claim depending on how the claimant frames it.

How Does Professional Indemnity Insurance Work?

PI insurance operates differently from most other business insurance. Two features determine whether you are properly covered.

The claims-made basis

The policy active when the claim is lodged responds. Not the policy active when the work was done.

This means: if a client makes a claim in 2026 about work you did in 2024, your current 2026 policy responds, provided the work falls after your retroactive date. If your policy lapsed before the claim arrived, no current policy responds.

The retroactive date

The retroactive date is the date from which your PI policy covers past work. Work performed on or after this date is covered. Work before it is not.

Three types exist:

• Policy inception date. Set to when you first took out continuous PI insurance. Stays fixed if you renew without gaps.
• Specific past date. Named date, typically when the business was established.
• Unlimited. Cover work performed at any point in the past.

The most common trap

Switching insurers can result in a new, later retroactive date being applied. This leaves all work done before that new date unprotected, even though continuous cover was held. Always confirm your retroactive date is maintained when switching or renewing. Check your policy schedule. If it has moved, ask your broker to reinstate it.

Run-off cover

Run-off cover extends the claim window after a policy is cancelled or not renewed. Because PI is claims-made, a claim arriving after your policy lapses has no policy to respond to it.

If you are winding up a business, retiring, or changing profession, confirm whether run-off cover applies before cancelling your PI policy.

Professional Indemnity vs Public Liability: What Is the Difference?

• Professional indemnity insurance may cover claims that your advice or professional work caused a client financial loss. The trigger is an alleged professional failure, subject to policy terms.
• Public liability insurance may cover claims when a third party is physically injured or their property is physically damaged. The trigger is a physical incident, subject to policy terms.

Most professional services businesses need both. The same incident can generate either type of claim depending on how it is framed.

How Much Does Professional Indemnity Insurance Cost?

The cost depends on your profession, annual revenue, selected cover level, and claims history. Based on 2026 Australian insurance market data, PI insurance for small businesses and sole traders typically starts from a few hundred dollars per year for lower-risk occupations at entry-level cover. Higher-risk professions and larger revenue levels attract higher premiums. Your actual premium will vary.

PI insurance premiums are generally deductible as a business operating expense under section 8-1 of the Income Tax Assessment Act 1997. Confirm with a registered tax agent.

Frequently Asked Questions

Does PI insurance cover a claim made after I stop working?

Only if you have run-off cover or a policy still active when the claim is lodged. Because PI is claims-made, the policy in force when the claim arrives responds. If your policy lapsed before the claim, there is no policy to respond to it. Run-off cover extends the window during which claims can be lodged after a policy ends.

What happens if I switch PI insurers?

Switching insurers can result in a new retroactive date being applied. This leaves past work uncovered even if you held continuous insurance. Always confirm your retroactive date is maintained when switching. If the new insurer sets a later date, ask your broker to negotiate reinstatement of the original date. Check your policy schedule on every renewal.

What is the difference between PI insurance and public liability insurance?

Professional indemnity insurance may cover financial loss claims arising from professional advice or services, subject to policy terms. Public liability insurance may cover physical injury or property damage claims arising from business activities, subject to policy terms. Most professional services businesses need both. One incident can generate either type of claim depending on how it is framed.

Is professional indemnity insurance tax deductible in Australia?

Generally yes. PI insurance premiums are typically deductible as a business operating expense under section 8-1 of the Income Tax Assessment Act 1997 for businesses where the policy relates to income-earning activities. Confirm your specific position with a registered tax agent.

Do I need PI insurance if I work through a company?

Yes in most cases. A company structure limits personal liability for debts but not necessarily for all claims arising from professional services. Many PI claims are directed at both the individual professional and the company. Industry body requirements and client contracts typically specify PI insurance regardless of business structure. Check your specific regulatory and contractual obligations.
