Quick answer. A genuine change of activity by a company subject to corporate income tax triggers a deemed cessation of business (Article 221-5 of the French Tax Code). It is characterised notably by a swing of more than 50% in turnover, or in both headcount and gross fixed assets. The result: immediate taxation of latent profits and permanent forfeiture of carry-forward losses.
You run a company that has accumulated losses and you are considering reshaping its model: adding an activity, dropping one, transferring a business unit. This routine-looking operational decision can trigger a heavy and irreversible tax consequence. If the tax authorities consider that a genuine change of activity has occurred, your company is deemed to have ceased its business. The stock of losses you planned to offset against future profits disappears.
This point is rarely anticipated. In strategic repositioning files, the most overlooked risk is not the cost of the transformation itself, but the loss of a patiently built tax asset. We set out here the mechanism of Article 221-5 of the French Tax Code, the thresholds that trigger cessation, the exemption by ministerial approval, and how to secure your loss carry-forwards in advance.
Why a change of activity forfeits losses#
For corporate income tax purposes, losses are a tax asset: they offset profits of subsequent years. Article 209 I of the French Tax Code allows an unlimited carry-forward in time, but capped each year at 1,000,000 euros, increased by 50% of the portion of profit exceeding that million. A loss-making company can therefore neutralise a significant share of its future profits, sometimes over several years.
Article 221-5 of the French Tax Code frames this advantage. When a company subject to corporate income tax undergoes a genuine change of activity, it is deemed to cease its business. This deemed cessation produces two cumulative and definitive effects:
- immediate taxation of operating profits not yet taxed and of latent capital gains (for example gains on fixed assets);
- forfeiture of the right to carry forward losses arising before the cessation: those losses can no longer be offset against later profits.
In other words, the company still exists legally, but for tax purposes it starts from scratch. The loss counter is reset. This is an anti-abuse measure, clarified by the amending finance act for 2012, whose stated aim was to end the trade in loss-making "shell" companies, emptied of their original activity and bought for their stock of losses.
Our reading#
The core issue is not the motivation behind the operation. You may have excellent economic reasons to pivot: a collapsing market, an opportunity to seize, a necessary repositioning. Article 221-5 does not judge intent, it measures the scale of the change. A perfectly legitimate reorientation can trigger cessation if it crosses the thresholds. It is this gap between entrepreneurial logic and tax reading that most often surprises directors.
What is a genuine change of activity#
The text does not rely on a subjective assessment. It sets numerical criteria. A genuine change of activity results notably from the addition, abandonment or transfer, even partial, of one or more activities, where this operation causes, in the year of its completion or the following year, a swing of more than 50% compared with the year preceding the operation:
- either in the company's turnover;
- or, cumulatively, in the average headcount of staff and the gross amount of fixed assets.
Also covered is the disappearance of the means of production needed to continue the activity, where this disappearance lasts more than twelve months (save in cases of force majeure), or is followed by a resumption of activity.
| Trigger | Cessation under Article 221-5? |
|---|---|
| Addition, abandonment or transfer of activity, with turnover swing above 50% | Yes, deemed cessation |
| Addition, abandonment or transfer, with combined swing above 50% in average headcount and gross fixed assets | Yes, deemed cessation |
| Disappearance of means of production for more than 12 months (save force majeure), or followed by a resumption | Yes, deemed cessation |
| Change of corporate purpose only in the bylaws, without change in the real activity | No, on its own |
| Organic growth in turnover without addition, abandonment or transfer of activity | No, in principle |
The underestimated risk: corporate purpose versus real activity#
Many directors believe they protect themselves, or conversely expose themselves, by amending the corporate purpose stated in their bylaws. This is a flawed analysis. A change of corporate purpose alone does not trigger a cessation of business. What matters is the activity actually carried out, measured by the numerical criteria. Conversely, keeping a very broad corporate purpose offers no protection if the economic flows shift: case law holds that maintaining a residual activity does not prevent the qualification of a genuine change of activity. An original activity kept "for show", but now marginal, is not enough to avoid cessation.
What the tax authorities look at#
The authorities reason on facts, not on declarations of intent. During an audit or a review of your situation, several indicators are examined first:
- the change in turnover by type of activity, from one year to the next;
- the composition of average headcount and the nature of roles before and after the operation;
- the gross amount of fixed assets allocated to the activity, and their renewal;
- the reality and continuity of the means of production;
- the timing: an operation carried out just before or after the acquisition of a loss-making company attracts attention.
The evidential stake is central. It is up to you to be able to demonstrate the continuity of the activity that generated the losses. Without solid documentation, you face the authorities' reading rather than shaping it.
The exemption by ministerial approval#
The legislature provided a safety valve. By way of exception, the cessation may be set aside if the company obtains prior ministerial approval. This approval is granted where the operations of addition, abandonment or transfer of activity are indispensable to the continuation of the activity that generated the losses and to the preservation of employment.
| Consequence | Without approval | With prior approval |
|---|---|---|
| Tax qualification | Deemed cessation of business | Cessation set aside |
| Immediate taxation of latent results | Yes | No |
| Fate of prior carry-forward losses | Permanent forfeiture | Carry-forward maintained |
| Process | No corrective option after the fact | Request to be filed before the operation |
The word "prior" is decisive. The approval is sought upstream, through a reasoned application. It cannot be obtained once the operation has been carried out. This is precisely why the trade-off must be addressed at the moment the reorientation project takes shape, not when the tax return is prepared.
In practice: how to secure your losses#
Here is the approach we recommend when a transformation project is on the table and the company carries significant losses.
- Map the stock of losses. Quantify the amount of carry-forward losses and the corporate tax saving they represent, given the annual cap of Article 209 I. This is the value of the asset you risk losing.
- Simulate the impact of the three criteria. Compare the year preceding the operation with the year of completion and the following year, on turnover, average headcount and gross fixed assets. Identify whether any criterion crosses 50%.
- Qualify the operation. Is it an addition, an abandonment, a transfer, even partial? Is there a risk of disappearance of the means of production for more than twelve months?
- Document continuity. Keep the evidence showing that the activity behind the losses genuinely continues: contracts, customers, human and material resources allocated.
- Study the exemption. If the operation is indispensable to the continuation of the activity and of employment, assess the option of a prior approval request, and prepare the file before any action.
- Set the filing calendar. Anticipate the obligations linked to a possible cessation, including filing the returns within a 60-day deadline.
Checklist before pivoting#
- Amount of carry-forward losses quantified and valued
- Turnover swing measured over N-1, N and N+1
- Combined swing of headcount and gross fixed assets measured
- Nature of the operation qualified (addition, abandonment, transfer)
- Continuity of the original activity documented
- Option of prior approval decided
- Cessation filing obligations anticipated (60-day deadline)
A common case: the SME that pivots#
A software-publishing SME accumulates losses over three years while funding its development. To rebound, it decides to abandon publishing and shift to a consulting and services activity for the same clients. The following year, more than 60% of turnover comes from consulting, which did not exist the previous year. The technical headcount is largely replaced by consultants.
On paper, the company survived and kept its name. Under Article 221-5, the abandonment of activity combined with a turnover swing above 50% characterises a genuine change of activity. The company is deemed to have ceased its business. The losses accumulated during the software phase are forfeited, even though they represented most of the company's tax value. An upstream analysis would have allowed either spreading the transition to stay below the thresholds, or filing an approval request.
This example is anonymised and illustrative. Each situation is assessed on its own flows and its own timing.
2026 points of vigilance#
- The measure targets companies subject to corporate income tax. Group structuring, the use of a holding company and any tax consolidation alter the analysis and warrant a dedicated review. Our articles on setting up a holding company and on moving cash up from a holding without friction shed light on these structures.
- The carry-forward cap of Article 209 I (1,000,000 euros, increased by 50% beyond) governs the real value of your stock of losses: losses you will never use have limited tax value. Our overview of corporate tax in 2026, standard and reduced rates completes this framing.
- The director's remuneration trade-off shapes the formation of losses; see our comparison dividend or salary in 2026.
- A reorientation often requires a bylaw amendment. The legal aspect is handled alongside the tax aspect: this is the purpose of our legal advice engagement, articulated with chartered accountancy and holding taxation.
Key takeaways#
- A genuine change of activity triggers a deemed cessation of business under Article 221-5 of the French Tax Code, with immediate taxation of latent results.
- The cessation entails permanent forfeiture of prior carry-forward losses: they can no longer be offset against future profits.
- The key threshold is a swing of more than 50% in turnover, or a combined swing in average headcount and gross fixed assets.
- A change of corporate purpose alone does not trigger cessation: what matters is the activity actually carried out.
- An exemption by prior ministerial approval exists where the operation is indispensable to the continuation of the activity and of employment.
- The trade-off is decided before the operation: once cessation is established, there is no retroactive remedy.
Frequently asked questions
When does a change of activity forfeit losses?+
When the operation is qualified as a genuine change of activity under Article 221-5 of the French Tax Code. This requires an addition, abandonment or transfer of activity causing a swing of more than 50% in turnover, or a combined swing in headcount and fixed assets.
What is a genuine change of activity?+
It is a transformation of the activity actually carried out, not of the corporate purpose alone. It results from the addition, abandonment or transfer, even partial, of activities, where the swing exceeds 50% of turnover, or of headcount and gross fixed assets, in the year of completion or the following year.
How can carry-forward losses be preserved?+
By measuring the impact of the three criteria of Article 221-5 before the operation, by documenting the continuity of the original activity, and, if the operation is indispensable to the activity and to employment, by requesting prior ministerial approval. The decision is made upstream, never after the fact.
Does a change of corporate purpose trigger a cessation?+
No, changing the corporate purpose alone in the bylaws does not trigger a cessation of business. It is the genuine change of activity, assessed on economic flows and the numerical criteria, that triggers cessation and the loss of carry-forwards, regardless of how the corporate purpose is drafted.
Does keeping a small original activity protect the losses?+
Not necessarily. Case law holds that maintaining a residual activity does not prevent the qualification of a genuine change of activity. An original activity that has become marginal is not enough to avoid cessation if the criteria of a swing above 50% are otherwise crossed.
How much can be carried forward for corporate tax?+
Article 209 I of the French Tax Code provides for an unlimited carry-forward in time, but capped each year at 1,000,000 euros, increased by 50% of the portion of profit exceeding that amount. This cap governs the real value of the stock of losses you risk forfeiting on a cessation.
What filing obligations apply on cessation?+
A cessation of business triggers filing obligations, including filing the returns within a 60-day deadline. It is prudent to anticipate this calendar from the project stage, in order to avoid a forced regularisation and to secure the treatment of the operation.
