5 PI Insurance Mistakes New Accounting Practices Make

Professional Indemnity insurance is one of those things most accountants know they need — but many don’t give enough attention to the detail. When you’re setting up a new practice, there’s a long list of things competing for your focus: client acquisition, systems, staffing, compliance, cash flow. Insurance can feel like a box to tick rather than a decision to get right.

That’s where mistakes happen. And with PI insurance, the consequences tend to surface at the worst possible time — when a claim lands on your desk.

Here are the five most common PI insurance mistakes we see new accounting practices make, and what to do instead.

Mistake 1:  Starting practice before cover is in place

Why it matters: Every major Australian professional body — CPA Australia, CA ANZ, IPA, and ATMA — requires you to hold PI insurance before you begin offering services to the public. Not after your first client. Not once things settle down. Before. If you start practising without cover, you’re in breach of your professional body’s requirements. That can trigger compliance action, suspension of your public practice certificate, or worse — a claim with no policy behind it.

What to do instead: Arrange your PI cover as part of your practice setup, not after launch. Build it into your pre-launch checklist alongside your ABN registration, business name, and professional body notification. A specialist provider like Abacus can typically turn around a quote within a day.

Mistake 2:  Underestimating fee revenue on the application

Why it matters: Your PI premium is partly calculated on your estimated annual fee revenue. It’s tempting to lowball the number when you’re just starting out — especially if you’re unsure how quickly the practice will grow. The problem is that if your actual revenue significantly exceeds your declared estimate, your cover may be inadequate. In the event of a claim, your insurer could argue that the policy was based on materially incorrect information. That can delay or reduce your payout — or in serious cases, void the policy entirely.

What to do instead: Provide your best honest estimate. If your revenue grows faster than expected, notify your insurer during the policy period. Adjustments are straightforward and protect you against a gap between what you declared and what you earned.

Mistake 3:  Not declaring all the services you offer

Why it matters: PI policies are structured around the services you provide. If you declare that you offer tax and BAS services, but you also start advising on SMSF, financial planning, or audit work without notifying your insurer, those additional services may not be covered. Different services carry different risk profiles. SMSF advice and audit work attract higher premiums because they carry higher claim potential. If your policy doesn’t reflect what you actually do, a claim arising from an undeclared service can be rejected.

What to do instead: Be comprehensive when listing your services at application. If you add new service lines during the policy period, notify your insurer immediately. A specialist provider expects service evolution and will adjust your cover accordingly — it’s a normal part of managing an accounting practice policy.

Mistake 4:  Choosing the cheapest policy without reading the wording

Why it matters: When you’re managing startup costs, the cheapest PI premium is appealing. But the lowest price almost always means the narrowest cover. Common trade-offs in cheaper policies include: professional negligence wording instead of civil liability (narrower), limited or no retroactive date, costs inclusive of the limit (your defence costs eat into your cover), no reinstatements (one claim exhausts your annual limit), and no run-off cover. These aren’t minor differences. They’re the difference between a policy that protects you and one that gives you a certificate but leaves critical gaps.

What to do instead: Compare policies on wording, features, and claims support — not just premium. Use a checklist to evaluate each option against the features that matter: wording type, retroactive date, reinstatements, costs treatment, run-off, and compliance alignment. The premium difference between adequate and inadequate cover is often surprisingly small.

Mistake 5:  Not notifying your professional body of your insurer

Why it matters: Most Australian accounting bodies require you to declare your PI insurance provider as part of your public practice certificate application or renewal. It’s easy to overlook this step, particularly when you’re focused on getting the policy itself sorted. But failing to notify your professional body means you’re technically non-compliant — even if you’re fully insured. Compliance action can follow, including suspension of your practice certificate.

What to do instead: Once your policy is confirmed, notify your professional body immediately. Keep your Certificate of Currency accessible and set a reminder to update it at each renewal. A specialist insurer will provide documentation that aligns with what your body requires.

 Bonus: Two More Mistakes Worth Mentioning

Forgetting about run-off when leaving a partnership

If you’re leaving a partnership or firm to start your own practice, you may need your own run-off cover for advice given while you were part of that firm. The firm’s continuing policy may not cover you once you’ve left. Check your partnership agreement and discuss this with your insurer before you transition.

Ignoring cyber risk

PI insurance covers professional advice and services. It doesn’t cover a data breach, ransomware attack, or email compromise. Accountants hold some of the most sensitive financial data of any profession. A cyber incident can be devastating — and increasingly common. Cyber insurance is a separate policy, but it’s one that every modern accounting practice should seriously consider.

How to Get It Right From Day One

The common thread in all five mistakes is the same: they happen when PI insurance is treated as a formality rather than a foundational business decision.

Getting it right means:

•  Starting the process early — before you begin practising

•  Being honest and thorough on your application

•  Comparing policies on features, not just premium

•  Keeping your insurer and professional body informed as things change

•  Working with a specialist provider who understands accounting practices
