The statute of limitations is a fundamental legal mechanism that limits the tax authorities’ right to make rectifications or recover debts over time. This principle protects taxpayers from indefinitely prolonged audits, while enabling the State to exercise its prerogatives within a reasonable timeframe. Understanding the statute of limitations is essential to anticipate the risks associated with a tax audit and secure your tax position.

What is the tax statute of limitations?

Tax prescription refers to the period of time after which the tax authorities can no longer exercise their right to rectify a taxpayer’s tax returns. This legal mechanism is based on the principle of legal certainty, and is designed to prevent taxpayers from remaining indefinitely under threat of reassessment.

In tax matters, there are two types of prescription: prescription of the right of recovery, which limits the period during which the administration can rectify your tax returns, and prescription of the right of collection, which limits the period during which you can recover established taxes.

Article L169 of the Livre des procédures fiscales (LPF) sets the standard recovery period at three years, while articles L176 and L188 of the LPF provide for extensions of this period in certain situations (failure to declare, concealed activity, fraudulent maneuvers). Article L274 of the LPF sets the limitation period for recovery at four years. These periods vary according to the nature of the tax, the type of irregularity found and the taxpayer’s conduct.

The standard trade-in period

Article L169 of the French Tax Procedures Code (LPF) sets a three-year recovery period for most taxes, subject to legal exceptions. The tax authorities can rectify your tax returns up to December 31 of the third year following the year in which the tax is due. This period applies to income tax (impôt sur le revenu – IR), corporation tax (impôt sur les sociétés – IS), VAT, registration fees and real estate wealth tax (impôt sur la fortune immobilière – IFI).

In concrete terms, for your income in 2024, the tax authorities have until December 31, 2027 to initiate rectification proceedings. However, there are a number of exceptions to this basic principle, which can considerably extend the time available to the tax authorities to take action, particularly in the case of failure to declare income or concealed activities.

Extended trade-in deadlines

Extension to six years in the event of failure to declare

Pursuant to Article L176 of the French Tax Code, failure to file a tax return within the legal time limit extends the recovery period to six years. This notion of failure to file a tax return primarily concerns the total absence of a tax return, and not simple omissions or errors in a filed tax return. This extension applies even if the failure to file is the result of a simple oversight with no fraudulent intent.

The tax authorities consider that a taxpayer who fails to declare his income or profits cannot benefit from the shortened three-year limitation period. This extension to six years is intended to penalize failure to comply with the fundamental obligation to declare income, irrespective of the taxpayer’s good faith.

Case law states that a tax return filed late, after expiry of the legal deadline for filing, does not prevent application of the six-year recovery period. The administration therefore retains this extended period even if the taxpayer spontaneously rectifies his situation after the initial deadline.

Extension to ten years for occult activity

The limitation period reaches ten years when the tax authorities establish the existence of a concealed activity, in accordance with article L169 paragraph 2 of the French Tax Procedures Code. An activity is considered to be concealed when you carry on a taxable activity without making yourself known to the tax authorities, without filing returns and without paying the corresponding taxes.

This qualification of “concealed activity” has particularly far-reaching consequences, as it enables the tax authorities to go back over a full decade. The jurisprudence of the Cour de cassation applies this notion strictly, and requires that three cumulative conditions be met: the exercise of a taxable activity, the absence of any declaration of existence to the administration (notably in the SIRENE register), and the failure to file any tax return relating to this activity. All three of these elements must be present in order to characterize a concealed activity.

Hidden activities must be distinguished from the simple concealment of income or revenue. A regularly declared taxpayer who underestimates his income or omits certain receipts is not in a situation of concealed activity, even if his behavior may constitute tax fraud. In this case, the recovery period remains limited to three years, unless there is evidence of fraudulent maneuvers justifying an extension to ten years on another legal basis.

Special cases and situations

Other extensions of the ten-year recovery period apply in specific situations. Proven fraudulent maneuvers (deliberate concealment, falsification of documents) are covered by article L169 of the LPF and give rise to this ten-year period. In the case of foreign assets, failure to declare foreign bank accounts in accordance with Article 1649 A of the CGI also triggers the ten-year time limit, even in the absence of undeclared income. Transactions carried out with non-cooperative states or territories (updated list available on the OECD website) may justify a similar extension of limitation periods.

The starting point of the limitation period

The limitation period begins to run from the taxable event, not the date of declaration or payment. In the case of income tax, the period begins on January 1 of the year following the year of the income concerned.

For corporation tax, the starting point is the first day of the financial year following that in which the tax is due. This rule applies regardless of when your company’s financial year ends.

In terms of VAT, the time limit runs from the taxable event, i.e. generally the delivery of goods or the completion of services. The complexity of these rules often justifies recourse to specialist advice.

Interruption and suspension of the statute of limitations

Certain events can interrupt or suspend the running of the tax statute of limitations. Interruption erases the period that has already elapsed and starts a complete new period, while suspension temporarily freezes the period without erasing it.

The main acts interrupting the tax statute of limitations include: notification of a proposal for rectification, which starts a new three-year period to enable the administration to establish the tax assessment; formal notice to pay, which interrupts the collection period and starts a new four-year period; the summons to pay and acts of seizure, which have the same interruptive effect; and finally, acknowledgement of debt by the taxpayer, whether express or tacit, which renews the collection period in full.

The causes of suspension of the limitation period have distinct characteristics. Litigation procedures suspend the time limit for their entire duration, from the initial claim to the final decision. Requests for information sent to foreign authorities in the context of international administrative assistance also suspend the time limit until receipt of the reply. Proceedings before the criminal courts for offences related to the taxes concerned freeze the statute of limitations until the final judgment.

To calculate the effective date of prescription, all interruptions and periods of suspension must be listed chronologically, and the periods concerned added together. Each interruption starts a new complete period (three years for the right to repossess, four years for recovery), while suspensions are added to the initial period without erasing it. This rigorous calculation method makes it possible to accurately determine whether the administration is acting within the legal time limits.

The statute of limitations on collection rights

Once the tax has been assessed, the tax authorities have a distinct period in which to obtain payment. According to article L274 of the French Tax Procedures Code, the limitation period for collection rights is four years from the date of assessment, i.e. from the date of receipt by the taxpayer of the tax assessment or collection notice. This four-year period applies both to initial assessments and to assessments issued following a tax audit.

This period may be interrupted by any legal action (formal notice, summons, seizure) or by an acknowledgement of debt from the taxpayer. Each interruptive act starts a complete new four-year period. In concrete terms, a tax assessed in 2024 must be collected before the end of 2028. If the administration carries out a seizure in 2027, the new period runs until 2031, thus extending the collection deadline by a further four years.

The distinction between the statute of limitations on the right of recovery and the statute of limitations on the right of collection is of vital importance. You may be time-barred from collecting a tax when the tax authorities were within the time limit for assessing it, and vice versa. These two periods run independently and are governed by separate rules.

The practical consequences of prescription

Once the statute of limitations has expired, the tax authorities can no longer legally rectify or demand payment of a tax claim. You then have absolute legal protection against any action by the authorities relating to the statute-barred period.

The statute of limitations is an objection that you can raise at any stage of the procedure, including before a judge. The administration itself cannot disregard an acquired statute of limitations, even if it subsequently discovers new elements.

In practice, compliance with the statute of limitations should be systematically checked upon receipt of a proposition de rectification or a avis de mise en recouvrement. This technical verification requires a precise analysis of the dates and any interruptive acts.

Securing your situation with regard to statute of limitations

Mastering tax statutes of limitation enables you to anticipate risks and organize your defense effectively. Keep your accounting documents for 10 years in accordance with Article L123-22 of the French Commercial Code, and your tax returns and supporting documents for a minimum of 6 years, and up to 10 years if you are at risk of being reassessed for concealed activity or if your tax situation is complex. This methodical storage is your first line of defense in the event of an audit.

When you receive a notification from the administration, check immediately whether it is within the legal time limit. Exceeding the statute of limitations is an absolute defense that must be raised without delay. For any reply to the tax authorities, systematically send it by registered letter with acknowledgement of receipt, which guarantees you proof of an enforceable date. You should also draw up a table showing the statute of limitations for each fiscal year: this schedule will enable you to quickly identify the periods that can still be audited and those that are definitively statute-barred.

Faced with the complexity of the applicable rules and their many exceptions, when in doubt about the applicable deadlines, or when faced with a complex procedure, calling on the services of a specialized advisor can help secure your defense. This expertise guarantees you a precise analysis of your situation and the best possible defense of your interests against the tax authorities.
