Professional liability insurance: requirements, coverage and accounting

Professional liability insurance (RC Pro) covers the financial consequences of the damage your business can cause to third parties. Many owners assume it is universal; others think it is optional. The truth depends on the profession. And beyond taking out cover, it is often the accounting for premiums and claims that causes problems. In our practice, we see insurance charges wrongly matched to the period, or indemnities mistakenly booked as a reduction of expense.

Quick answer. Professional liability cover is mandatory for many regulated professions (real estate agents under the Hoguet Act, accountants and statutory auditors, healthcare professionals, lawyers, notaries) and, in construction, ten-year structural liability cover is required by Article L241-1 of the Insurance Code. For other SMEs it is optional but strongly recommended. In accounting, the premium is booked as an expense (account 616); when it spans two fiscal years, deferred expenses (account 486) are used; an indemnity received is booked as income, never as a reduction of expense.

The obligation is not general: it targets professions exposed to particular risk towards third parties or clients.

Our reading. For real estate agents, the Hoguet Act separates two things: professional liability (required to obtain the licence) and the financial guarantee, required only when handling client funds (management, syndic). The minimum financial guarantee cannot be below EUR 110,000 per activity (reduced to EUR 30,000 for the first two years). Do not confuse the financial guarantee with professional liability: the former protects client funds, the latter repairs damage caused.

For other businesses (retail, industry, services), professional liability is optional by law, but often required by banks, insurers and contracting parties, notably in public procurement. An uninsured claim can weigh heavily: damages, defence costs, business interruption.

General liability#

It covers material or bodily damage caused to third parties during operations, outside the intellectual service itself: a client who falls on your premises, a delivery that damages a client's property, a tool that damages a building facade.

Professional liability#

It covers losses arising from a fault, error or omission in the service: faulty advice, a missed deadline, an unsuitable recommendation. It is the key cover for intellectual and regulated professions.

Ten-year structural guarantee (construction)#

It covers defects compromising the solidity of the works or making them unfit for purpose, discovered within ten years of completion (Civil Code Articles 1792 et seq.). Insuring it is mandatory (Insurance Code Article L241-1). It does not cover normal wear.

This is the angle we handle most often. Correct accounting drives deductibility and a true and fair view of profit.

The insurance premium#

The premium is recorded as an operating expense, account 616 "Insurance premiums". When the premium covers a full fiscal year, the whole amount is the year's expense.

Entry (annual premium paid in advance, year fully covered): debit account 616 "Insurance premiums"; credit account 512 "Bank".

A premium spanning two fiscal years#

This is the common case of a premium paid mid-year for a period crossing the year-end. The matching principle requires booking to the year only the consumed portion.

At year-end, a deferred expense is recognised: debit account 486 "Deferred expenses"; credit account 616. The deferred portion matches the months covered in the following year. It is expensed during Year N+1.

Example: a EUR 1,200 premium covering 1 October Year N to 30 September Year N+1 represents EUR 300 of expense in Year N (three months) and EUR 900 of deferred expenses carried to Year N+1.

Common pitfall. Booking the whole premium in the year of payment distorts profit. The expense must follow the period actually covered.

The claim indemnity received#

When the insurer pays you an indemnity, it is recorded as income — account 791 "Expense transfers" when it reimburses an already-booked expense, or exceptional income (account 778) on the loss of an asset — and never as a reduction of the original expense account: it compensates a loss, it does not erase the expense incurred.

The deductible#

The deductible stays with you: it is booked as an expense of the year. It is not recoverable from the insurer, by definition.

Micro-enterprise#

The premium follows the same expense logic; but under the micro regime, expenses are not deducted at actual cost (the flat allowance accounts for them). Professional liability remains a useful, sometimes mandatory, outlay depending on the trade.

Real estate partnership (SCI)#

Insurance of the property (owner's liability, cover of let premises) is recorded at SCI level, not at the partner's level.

A claim resolved in a later year#

If the outcome of a dispute is only known one or two years later, a provision is recognised while an outflow of resources is probable, then released when the indemnity or the award becomes certain.

• Cover of digital risks. Check that your policy covers intangible damage (data loss, business interruption). Cyber insurance often complements classic professional liability.
• Rising premiums. Inflation in claim costs pushes premiums and deductibles up: renegotiate every two to three years, especially if claim-free.
• Adequate limits. An under-sized guarantee leaves a balance to bear on a large claim. Match limits to your real exposure.
• Accounting traceability. A poorly matched premium (expense not spread, indemnity booked against expense) is exposed to challenge on audit.

A construction SME recently consulted us to audit its cover: it combined the ten-year guarantee and general liability in a single policy, without clearly distinguishing the guarantees. On a claim, the insurer applied the deductible specific to each guarantee, where the owner expected only one. Reading the policy with a specialised broker would have clarified how the guarantees fit together and avoided the unpleasant surprise.

Hayot Expertise advice. Review your policy at least every three years: check that limits match your risks, that deductibles are consistent, and that premiums are properly booked (account 616, deferral to 486 if the premium crosses the year-end). A well-chosen, well-recorded policy means peace of mind and a correctly stated tax charge.

• Mandatory for regulated professions (Hoguet, accountants/auditors, healthcare, lawyers, notaries) and, in construction, for ten-year structural liability (Insurance Code L241-1).
• Three guarantees to distinguish: general liability (third-party damage), professional liability (service errors), ten-year (construction defects over 10 years).
• Premium booked to account 616; spread to deferred expenses (486) if it spans two fiscal years.
• Indemnity received as income, never as expense reduction; deductible borne by you.
• Review your policy every two to three years and align limits with your exposure.
