Prescription of Inheritance Tax: Up to 10 Years in Case of Fraud

Imagine: you have just lost a loved one and, while sorting through their papers in Romilly-sur-Seine, you come across a bank statement showing a transfer of €50,000 to another family member. Your notaire explains that this might be an undeclared manual gift. You breathe a sigh of relief: the 3-year prescription period has passed. But is it really over?

The question every heir asks: can the tax authorities revisit an inheritance after several years if they suspect fraud? How far back can they go?

In a decision of 31 January 2012, the Court of Cassation ruled: when the authorities must conduct additional investigations to discover the true nature of an act (for example, a concealed manual gift via a power of attorney), the recovery period is no longer 3 years but 10 years. A difference that can change everything, as we will see.

The facts: a story like many others

Mr X, a resident of Bar-sur-Seine, died in 2000. His inheritance was declared by his children, who mentioned bank accounts and a property. However, the tax authorities, while checking the statements, discovered a strange withdrawal of €80,000 three years before Mr X's death, followed by a transfer to his daughter's account. The daughter claimed it was a loan, but no written evidence or repayment supported this version.

The tax agents conducted further investigations: they questioned the bank, examined the powers of attorney, and uncovered that the daughter had a general power of attorney and had withdrawn the funds without any consideration. In their view, this was a manual gift (a donation without a notarial deed) that should have been subject to transfer taxes. However, the gift was never declared in the inheritance.

The authorities notified a reassessment in 2006, over 3 years after the registration of the inheritance return. The family contested: for them, the 3-year recovery period (Article L. 180 of the Tax Procedures Book, LPF) had expired. The court initially ruled in favour of the family. But the Reims Court of Appeal, followed by the Court of Cassation, held that the ten-year prescription (Article L. 186 LPF) applied because the exact nature of the act (manual gift) was not discernible from the inheritance return alone. Subsequent investigations were necessary. The reassessment was upheld.

The reasoning of the court — dissected

The judges applied a two-step reasoning. First, they recalled the general law: Article L. 180 LPF sets a 3-year recovery period for registration duties, running from the registration of the act (here, the inheritance return). This period applies even if the authorities discover an omission, provided the act is sufficiently explicit. But beware: if the authorities must conduct "further investigations" to establish the tax liability, then the ten-year prescription of Article L. 186 (in its version then in force) applies.

In this case, the inheritance return only mentioned a current account and a house. The manual gift of €80,000 appeared nowhere. To detect it, the tax authorities had to use investigative powers: request bank statements, reconstruct movements, analyse the power of attorney. This constitutes "further investigations" within the meaning of the law. The Court of Cassation therefore confirmed that the shortened prescription (3 years) is set aside in favour of the ten-year period.

The decision is not a departure from precedent: it follows a line of case law that protects the authorities against opaque arrangements. However, it clarifies a key point: the mere existence of a power of attorney does not make the act transparent. As long as the authorities cannot immediately ascertain the composition of the assets and the tax liability, the long period applies.

What this means for you — in practical terms

For heirs, this decision means that silence or an omission in an inheritance return can resurface long after the three-year mark. Concrete example: in Bar-sur-Seine, an heir received a back-tax demand for €15,000 plus late interest, 7 years after his mother's death, for an undeclared manual gift of €40,000. Without this ruling, the tax authorities would have been time-barred.

For donors (those who make a manual gift), the risk is twofold: the gift is generally exempt from tax up to €100,000 between close relatives, but it must be declared (Cerfa form). If you omit this declaration, the authorities can catch up with you for 10 years.

For professionals (notaires, advisors), it is imperative to inform families of this long period as soon as a suspicious element appears. An overly concise inheritance return may conceal a tax liability.

If you are in this situation, you must check whether the disputed facts were "hidden" or simply poorly documented. If the authorities had to conduct extensive investigations to discover them, the 10-year period applies. Otherwise, the 3-year period runs from the registration.

Four tips to avoid this type of dispute

• Declare all manual gifts, even between close relatives, using form 2735. The cost is nil or minimal (depending on allowances) but avoids the long prescription period.
• Keep supporting documents for money transfers (bank transfers, cheques) for at least 10 years after the transaction. In the event of an audit, you can prove the nature of the flow (loan, gift, etc.).
• Do not rely on a power of attorney to mask a liberalité: case law treats the improper use of a power of attorney as a manual gift if the funds are diverted to the agent's benefit.
• Consult a notaire for any significant gift, even between individuals. An authentic deed secures the evidence and opens the 3-year period from its registration.

Further reading: related case law and developments

The Court of Cassation had already set milestones in a decision of 12 May 2004 (No. 03-14.875), holding that the ten-year prescription applies when concealment results from fraudulent actions. Here, the 2012 decision extends this principle to cases where fraud is not obvious but requires investigations.

Conversely, in a decision of 10 July 2013 (No. 12-25.321), the Court applied the 3-year period because the inheritance return contained sufficient information to allow the authorities to verify without further investigation. The line is therefore fine.

Since 2012, the trend has been towards strengthening the tax authorities' control powers: the ten-year prescription becomes the rule for any opaque transaction. Legal professionals must be extra vigilant when preparing inheritance returns.

What you absolutely must remember

Here is a checklist of reflexes to adopt:

1. Check the deceased's accounts over the last 10 years: any abnormal withdrawal may be reclassified as a manual gift.
2. Declare without delay any gifts made before the death, even if you think they are prescribed.
3. In the event of an audit beyond 3 years, do not assume the period is time-barred: ask a lawyer whether the authorities had to conduct investigations.
4. Keep in mind that the amount of tax may be increased by 40% in case of bad faith (Article 1729 of the General Tax Code).
