Professional indemnity insurance is business cover that pays claims arising from professional advice or services that cause a customer financial loss.

Also known as: PI insurance, professional liability insurance, indemnity cover

Key points

  • It responds to claims of negligence, errors or omissions in your work, and pays the legal costs of defending them.
  • Licensed occupations often must hold it: brokers, accountants, advisers, engineers, architects and medical practitioners are common examples.
  • Most policies are claims made, so cover must be current when the claim is made, not when the work was done.
  • It does not cover injury or property damage from your day to day operations: that is public liability.
  • Holders of an Australian credit licence must have compensation arrangements in place, usually satisfied by this insurance.

Frequently asked questions

What does professional indemnity insurance cover?

Claims that your professional advice or services were negligent, wrong or incomplete and caused a financial loss. It pays compensation up to the policy limit and the legal costs of defending the claim. Some policies extend to defamation, loss of documents and breaches of confidentiality. Check the policy wording.

Who needs professional indemnity insurance?

Anyone selling skill or advice. It is compulsory for many licensed occupations, including financial services and credit licensees, medical practitioners, lawyers and building surveyors, certifiers and design practitioners in some states. Others take it because client contracts demand it or because a single error could sink the business.

Is professional indemnity the same as public liability?

No. Public liability covers physical harm: a customer injured on your site or property you damage while working. Professional indemnity covers economic loss from your advice or work product. Many consultants carry both, because a single job can create either kind of exposure.

What does claims made cover mean?

The policy that responds is the one in force when the claim is made against you, not the one you held when you did the work. That is why you keep cover going after finishing a project, and why run off cover matters when you retire or sell the business.

Is professional indemnity insurance tax deductible?

Premiums for cover taken out to protect a business are generally deductible as a business expense in the year paid. Treatment can differ if the policy covers private activity or a period before trading started. Confirm with your accountant or check the ATO's guidance on business insurance.
