PI claims examples: bookkeepers

How to read these scenarios

The scenarios below are generic illustrations of how professional indemnity claims typically arise in this profession. They are composite, hypothetical patterns for explanation only, not descriptions of real cases, clients or firms, and how any actual policy responds always depends on its own terms.

The shape of a bookkeeping claim is usually a client who has paid penalties, interest or extra professional costs because of an error in the records or the filings, and who looks to the practice to make it good. PI insurance typically funds the defence and pays what the practice is liable for, up to the limit and subject to the excess and terms.

Scenario 1: a VAT return error that compounds

A coding error means a category of transactions is treated wrongly for VAT, and the mistake repeats every quarter until an accountant or an HMRC check catches it. The client faces assessments, interest and penalties across multiple periods and claims the cost from the bookkeeper.

Compounding is the point: each individual error is small, and the total is not. PI responds in the ordinary way, and the buying lesson is to think about limits in terms of accumulated exposure across periods and clients, not the size of any single mistake. It is also a reminder that an aggregate limit can erode faster than expected when one root cause produces several claims.

Scenario 2: payroll misprocessed

A payroll run applies the wrong treatment to part of the workforce for months. Employees are underpaid or overpaid, corrections and employer costs follow, and the client claims the cost of putting it right.

The insurance lesson here is about boundaries. The client’s claim against the practice for negligent payroll work is PI territory. Employers’ liability insurance is entirely different: it is the employer’s statutory cover for injury to its own employees, not a payroll backstop, and it belongs to the client’s programme, not yours. A practice running payroll should simply make sure payroll is declared as an activity on its own PI.

Scenario 3: a software migration that loses data

Moving a client from one bookkeeping platform to another, part of the history does not survive: opening balances are wrong, transactions are missing, and the year-end accounts and filings built on the migrated data need expensive reworking.

Digital practice creates digital claims. The lesson is disclosure: migrations, bank feeds, automation rules and app integrations are all part of what a modern practice does, and the policy’s activity description and the insurer’s understanding should reflect that. An old policy that predates your software-led way of working is worth re-describing at the next renewal.

Scenario 4: a filing missed, penalties follow

A practice responsible for a client’s submissions misses a deadline, penalties and interest accrue, and the client claims them back along with the accountancy costs of tidying up.

Like the missed election in tax work, this is a diary failure rather than a judgement failure, which is why it is among the most frequent patterns. It is also the pattern most sensitive to engagement letters: a clear record of who files what, by when, decides these disputes. The buying lesson is administrative honesty, and the practice lesson is that scope in writing is cheap insurance of its own.

Scenario 5: scope creep into tax advice

A long-standing client asks a competent, helpful bookkeeper a tax question, and the answer goes beyond bookkeeping into advice the practice is neither qualified for nor insured to give. The advice proves wrong and the client claims.

This is the quiet one, and the most instructive. A policy priced and worded for bookkeeping may not respond to a tax advice claim, precisely because the activity was never declared. The lessons: describe your activities accurately, decline or refer work beyond them, and if the practice genuinely wants to offer tax services, tell the insurer and buy the cover deliberately. AAT and ICB practice rules point the same way: work within the services your licence and your insurance actually cover.

What the patterns teach about buying cover

Three habits deal with almost everything above. First, describe the practice as it is: payroll, VAT, MTD filings, software work and anything approaching advice, all declared. Second, keep the claims-made mechanics intact: continuous cover, a preserved retroactive date through any broker or insurer change, and run-off when the practice closes. Third, put scope in writing with every client, so the argument about who was responsible for what never has to happen. None of this is expensive; all of it decides claims.

Frequently asked questions

Are these real claims against real bookkeeping practices?

No. They are generic, hypothetical illustrations of the claim patterns most associated with bookkeeping work, written to show how PI insurance typically responds. They describe no actual case, client or firm, and any real policy’s response depends on its own terms and facts.

Does PI cover HMRC penalties my client suffers because of my error?

A client’s claim to recover penalties, interest and associated costs caused by your negligent work is the sort of loss PI policies typically respond to, subject to the policy’s terms. The penalties are the client’s; what PI covers is your liability to make them good.

Is payroll covered by employers’ liability insurance?

No. Employers’ liability is the statutory cover an employer holds for injury to its own employees. Claims about negligent payroll processing are professional negligence claims against your practice, which is PI territory, so payroll should be declared as an activity on your PI policy.

What if I answered a tax question and it went wrong?

Notify your insurer promptly and be candid about what was said. Whether the policy responds will depend on the activities it covers, which is exactly why advice beyond your declared services is dangerous. The durable fix is to declare tax work properly or refer it on.

How big a limit does a small bookkeeping practice need?

There is no universal figure. Think about accumulated exposure: errors that compound across VAT quarters, payroll runs and clients, plus defence costs. Your professional body’s requirements set a floor, and your client base and work mix should set the working answer with your broker.
