Professional indemnity insurance typically costs between $40 and $250 per month for most Australian small businesses and professionals. Low-risk sole traders (IT consultants, freelancers, bookkeepers) sit at the lower end. Architecture, engineering, and financial services sit higher.

Your actual cost depends on your industry, annual turnover, number of employees, cover level, and claims history. Unlike public liability, which covers physical injury and property damage, PI covers financial loss caused by your professional advice or service errors. Because a single bad recommendation can trigger a large compensation claim, PI premiums are typically higher than PL for the same business.

At a Glance

• Most sole traders pay $40 to $100 per month for professional indemnity insurance. Small businesses with employees pay $120 to $250 per month.
• Doubling your cover from $1 million to $2 million does not double your premium. The increase is typically 20 to 30% because maximum payouts are statistically uncommon.
• More employees means a higher premium. You carry vicarious liability for the advice your staff give, not just your own.
• PI is claims-made insurance. Your policy must be active when the claim is lodged, not just when the work was done. Maintaining continuous cover matters.
• Premiums are generally tax-deductible under section 8-1 of the Income Tax Assessment Act 1997 to the extent they relate to earning assessable business income.

Average Professional Indemnity Insurance Cost by Industry

Your profession is the biggest factor in your premium. Higher-risk advice with larger potential financial consequences costs more to insure.

Ranges based on published Australian industry data from multiple broker and insurer sources, 2024-2026. Indicative only. Your actual cost depends on your specific circumstances.

Professional Indemnity Insurance Cost by Cover Level

The cover level is the maximum your insurer will pay for a single claim (or in aggregate across the policy year). Higher cover costs more, but the increase is not proportional.

Upgrading from $1 million to $2 million typically adds 20 to 30% to your premium, not 100%. The step-up is cost-effective because maximum payouts are uncommon. For help choosing the right level, see upcover's guide on what level of PI cover you need.

How Business Size Affects Your PI Cost

More employees means more people giving advice under your ABN. Insurers call this vicarious liability. You are responsible for the professional errors of your staff, not just your own.

• Sole trader (no employees): $40 to $100/month. Lowest tier — you are the only source of professional risk, so the insurer's exposure is limited to your individual advice and output.
• 1 to 3 employees: $100 to $160/month. Each additional person giving advice under your ABN adds a layer of vicarious liability, even if they are part-time or on contract.
• 3 to 5 employees: $150 to $200/month. At this size, insurers factor in team supervision gaps — the more people delivering work, the harder it is to quality-check every engagement.
• 5+ employees: $180 to $300+/month. Premiums scale with headcount and turnover. Larger teams typically handle more clients simultaneously, increasing the probability of an error reaching a third party.

Higher annual turnover also increases your premium. More revenue means more client engagements, more advice given, and more exposure to potential claims.

Who Must Legally Have Professional Indemnity Insurance?

PI is not legally required for every business. But it is required or expected for many professions and frequently demanded by client contracts. PI requirements vary by profession and may arise from legislation, regulator standards, licence conditions, professional association rules, public-practice certificates, or client contracts.

Professions where PI is commonly required include:

• Financial advisers (ASIC)
• Tax practitioners and BAS agents (Tax Practitioners Board)
• Lawyers (state law societies)
• Architects (state registration boards)
• Migration agents (Office of the MARA)
• Registered health practitioners (depending on registration and work type)
• Some real estate agents (depending on state licensing)
• Some accounting professionals (depending on licence, registration, and membership category)

Practically required:

• Any professional whose client contract specifies PI as a condition
• Consultants bidding on government or corporate tenders
• Businesses working with enterprise procurement portals (Cm3, Felix)

If your profession is not on the mandatory list, check your contracts. Many clients and head contractors require PI regardless.

What Else Affects PI Cost?

• Industry and occupation. Architecture and financial services cost more than general consulting.
• Annual turnover. Higher revenue means more engagements and more risk exposure.
• Number of employees. More staff giving advice means more vicarious liability.
• Cover level. $1 million to $10 million. Higher cover costs more but not proportionally.
• Claims history. Past claims push your premium up. A clean record helps.
• Excess. A higher excess (your out-of-pocket contribution per claim) reduces your premium.
• Retroactive date. PI is claims-made insurance. Your premium reflects your historical liability footprint back to your policy's retroactive date. Maintaining continuous cover without gaps keeps this date as early as possible, which protects you against older claims.

Two Ways to Pay Less

Bundle PI with PL: Arranging professional indemnity and public liability together under a single policy or business pack typically saves 10 to 15% compared to buying them separately.

Claim the tax deduction: PI premiums are generally tax-deductible as a business operating expense under section 8-1 of the Income Tax Assessment Act 1997 to the extent they relate to earning assessable business income. If you purchase or renew before 30 June, you may be able to claim the deduction in the current financial year. Confirm with a registered tax agent.
