Since 1 January 2018, gains from life insurance contracts in France have been subject by default to the Prelevement Forfaitaire Unique (PFU), commonly known as the flat tax, at an overall rate of 30%. However, taxpayers retain the option to choose the progressive income tax scale. This choice, governed by Article 200 A of the Code General des Impots (CGI), can have significant financial consequences ranging from a few dozen to several thousand euros depending on the situation. Understanding the mechanics of each option and knowing which one suits your profile is essential for optimising your tax position.
What the 30% PFU comprises
The PFU breaks down into two distinct components whose respective nature must be well understood:
- 12.8% income tax (or 7.5% for contracts over 8 years old within the 150 000 euro contribution limit)
- 17.2% social charges (CSG at 9.2%, CRDS at 0.5%, solidarity levy at 7.5%)
This overall rate of 30% applies only to the capital gains portion included in the withdrawal, not to the full amount withdrawn. It is essential to remember that social charges of 17.2% remain due whichever option is chosen between PFU and progressive scale. Only the income tax component (12.8% or 7.5%) can be replaced by the progressive scale.
In practice, when a withdrawal is made, the insurer deducts an advance of 12.8% (or 7.5% for contracts over 8 years old) plus social charges of 17.2%. If the taxpayer subsequently opts for the progressive scale when filing their tax return, the advance is adjusted: any overpayment is refunded if the marginal tax rate (TMI) is lower than the advance rate.
The progressive income tax scale in detail
The progressive income tax scale for 2026 (2024 income) is as follows:
- 0% up to 11 294 euros
- 11% from 11 295 to 28 797 euros
- 30% from 28 798 to 82 341 euros
- 41% from 82 342 to 177 106 euros
- 45% above 177 106 euros
When the taxpayer opts for the progressive scale, life insurance gains are added to all other taxable income. The tax then depends on the marginal tax rate (TMI). Note that the TMI is the rate applied to the last bracket of income, not the average tax rate. A taxpayer with a TMI of 30% does not pay 30% on all their income, but only on the portion above 28 797 euros.
| Criterion | PFU (flat tax) | Progressive scale |
|---|---|---|
| Income tax rate (contract < 8 years) | 12.8% fixed | According to TMI: 0%, 11%, 30%, 41%, 45% |
| Income tax rate (contract > 8 years, contributions ≤ 150 000 euros) | 7.5% fixed | According to TMI |
| Social charges | 17.2% | 17.2% |
| Deductible CSG (6.8%) | No | Yes |
| 4 600 / 9 200 euro allowance (contract > 8 years) | Yes | Yes |
| Application | By default | By election (box 2OP) |
| Scope of the choice | Automatic | Global across all investment income |
When is the PFU more advantageous?
The PFU is generally more attractive for taxpayers with a TMI of 30% or above. In that case, the flat rate of 12.8% is significantly below the marginal rate that would apply to gains. The difference can amount to several thousand euros for large withdrawals.
For contracts over 8 years old with contributions not exceeding 150 000 euros, the reduced rate of 7.5% makes the PFU particularly competitive. In this configuration, even taxpayers with a TMI of 11% will pay more under the progressive scale than under the PFU, since 11% exceeds 7.5%. This is a point many savers overlook.
Worked example: Marc, 52, senior secondary school teacher (agrege)
Marc, 52, is a senior secondary school teacher in Paris. Single, his taxable income is 42 000 euros, placing him in the 30% bracket. He has a Linxea Spirit 2 life insurance contract opened 6 years ago, into which he has contributed 80 000 euros. The contract is now worth 98 000 euros. Marc makes a partial withdrawal of 15 000 euros to finance renovations in his apartment.
Calculating the gains portion in the withdrawal:
- Total gains: 98 000 - 80 000 = 18 000 euros
- Gains in the withdrawal: 15 000 - (80 000 x 15 000 / 98 000) = 15 000 - 12 244.90 = 2 755.10 euros
With the PFU:
- Income tax: 2 755.10 x 12.8% = 352.65 euros
- Social charges: 2 755.10 x 17.2% = 473.88 euros
- Total: 826.53 euros
With the progressive scale (30% TMI):
- Income tax: 2 755.10 x 30% = 826.53 euros
- Social charges: 2 755.10 x 17.2% = 473.88 euros
- Deductible CSG: 2 755.10 x 6.8% = 187.35 euros, yielding a saving of 187.35 x 30% = 56.20 euros
- Net total: 1 244.21 euros
The PFU saves Marc 417.68 euros. For a teacher in the 30% bracket, the PFU is unambiguously the better choice on a contract under 8 years old.
When is the progressive scale more advantageous?
The progressive scale becomes attractive in two main situations, affecting a significant number of taxpayers.
Low TMI (0% or 11%)
If your TMI is 0% or 11%, the progressive scale is mechanically more advantageous than the flat 12.8% rate for contracts under 8 years old. A non-taxable taxpayer who accepts the PFU by default without ticking box 2OP loses money unnecessarily. This situation applies notably to low-pension retirees, students who have inherited a contract, or people on a sabbatical with reduced income.
For taxpayers with an 11% TMI, the saving is 1.8 percentage points (12.8% - 11%), plus the benefit of deductible CSG. On gains of 10 000 euros, this represents 180 euros in direct savings plus approximately 75 euros from deductible CSG, for a total gain of around 255 euros.
Deductible CSG: an often overlooked advantage
By opting for the progressive scale, a portion of the CSG (6.8% out of 9.2%) becomes deductible from taxable income, pursuant to Article 154 quinquies of the CGI. This deduction can represent a non-negligible additional benefit, especially for taxpayers receiving substantial investment income taxed under the progressive scale.
For a gain of 10 000 euros, deductible CSG amounts to 680 euros. For a taxpayer with an 11% TMI, this generates an additional saving of 74.80 euros. At a 30% TMI, the saving would be 204 euros, but it does not compensate for the extra cost of the marginal rate being above 12.8%.
The 40% allowance on dividends: an argument in favour of the progressive scale
When you opt for the progressive scale, share dividends benefit from a 40% allowance before taxation, which considerably reduces their effective rate. A taxpayer with an 11% TMI receiving both life insurance gains and dividends often benefits from ticking box 2OP, as the allowance on dividends can more than offset any extra cost on other investment income. Remember to simulate the overall impact before validating your return.
The special case of contracts over 8 years old
For contracts over 8 years old, the PFU income tax rate drops to 7.5% (instead of 12.8%) for gains corresponding to contributions not exceeding 150 000 euros. This reduced rate, combined with the annual allowance of 4 600 euros (9 200 euros for a couple), makes the PFU particularly competitive after 8 years.
The 150 000 euro threshold is assessed per taxpayer and across all contracts held. For a married or civil-partnered couple, each partner has their own threshold, giving 300 000 euros in total. This is a crucial point for couples with significant life insurance holdings. Contracts such as Lucya Cardif or Boursorama Vie make it easy to open a contract in each partner's name to optimise this allocation.
Worked example after 8 years
Consider a married couple who withdraw 15 000 euros of gains from a contract over 8 years old (contributions below 150 000 euros).
With the PFU:
- Allowance: 9 200 euros
- Taxable base: 15 000 - 9 200 = 5 800 euros
- Income tax: 5 800 x 7.5% = 435 euros
- Social charges: 15 000 x 17.2% = 2 580 euros
- Total: 3 015 euros
With the progressive scale (11% TMI):
- Allowance: 9 200 euros
- Taxable base: 5 800 euros
- Income tax: 5 800 x 11% = 638 euros
- Social charges: 15 000 x 17.2% = 2 580 euros
- Total: 3 218 euros
Even with an 11% TMI, the PFU at 7.5% is more advantageous by 203 euros. The deductible CSG of 15 000 x 6.8% = 1 020 euros generates only an additional saving of 112.20 euros (at 11% TMI), insufficient to close the gap. The verdict is clear: after 8 years, unless the TMI is 0%, the PFU at 7.5% almost always wins.
The option is global: beware of the trap
A fundamental point to remember: the option for the progressive scale is global. It applies to all investment income received during the year (dividends, interest, securities capital gains). It is impossible to apply the PFU to some income and the progressive scale to others. This rule, set out in Article 200 A, 2 of the CGI, requires simulating the overall impact before making a choice.
This globality can create paradoxical situations. For example, a taxpayer with an 11% TMI who would benefit from the progressive scale for their life insurance gains could be penalised if, in the same year, they realised securities capital gains on a standard brokerage account. Conversely, large dividends benefiting from the 40% allowance can make the progressive scale more favourable overall, even if certain income items would individually be better treated under the PFU.
Warning: the option is irrevocable for the year
Once your tax return is definitively validated, you can no longer reverse the PFU/progressive scale choice for that year (except through a formal dispute within the statutory time limits). Take the time to simulate both scenarios on impots.gouv.fr before validating. The site's simulator allows you to compare results by ticking and unticking box 2OP. This few minutes of precaution can save you several hundred euros.
How to make your choice in practice
The option for the progressive scale is exercised when filing the annual tax return, by ticking box 2OP on form 2042. By default, without any action by the taxpayer, the PFU applies. The process is as follows:
- Gather your documents: the IFU (Imprime Fiscal Unique) from your insurer, dividend statements, capital gains summaries
- Calculate your TMI by including all income, including life insurance gains
- Simulate both options on the impots.gouv.fr website by filling in your return once without box 2OP, then a second time with it
- Factor in deductible CSG if you opt for the progressive scale: it reduces your taxable income for the year
- Consider all investment income, not just life insurance: dividends with the 40% allowance, capital gains with possible holding period allowances
- Compare the tax amounts calculated in both scenarios and choose the most favourable
For taxpayers with contracts at several insurers (for example a Boursorama Vie contract and a Linxea Spirit 2 contract), you must add up all gains and contributions to get a coherent overall picture.
Mixed situations: multiple contracts and multiple regimes
Complexity increases when the taxpayer holds several contracts of different ages, with contributions split before and after 27 September 2017. In that case, gains from each contract may fall under different rates within the PFU itself, while the progressive scale applies a single rate (the TMI) to all.
A taxpayer may have a contract under 8 years old (PFU at 12.8%) and a contract over 8 years old (PFU at 7.5%). If they opt for the progressive scale, their TMI rate applies to both. With an 11% TMI, the progressive scale would be advantageous on the first contract (11% < 12.8%) but disadvantageous on the second (11% > 7.5%). The overall calculation will determine the optimal choice.
Summary: which choice for your profile?
| Situation | Recommended option | Comment |
|---|---|---|
| TMI at 0% | Progressive scale | Maximum income tax saving |
| TMI at 11%, contract < 8 years | Progressive scale | 11% < 12.8% + deductible CSG |
| TMI at 11%, contract > 8 years | PFU at 7.5% | 7.5% < 11% despite deductible CSG |
| TMI at 30% | PFU | 12.8% significantly < 30% |
| TMI at 41% or 45% | PFU | Very large gap in favour of PFU |
| Large dividends + 11% TMI | Simulate both | The 40% allowance can change the outcome |
| Diversified investment income | Full simulation | The option is global, not selective |
Conclusion
The choice between PFU and progressive scale fundamentally depends on your marginal tax rate and the overall composition of your investment income. Taxpayers with a TMI of 0% or 11% with contracts under 8 years old almost always benefit from ticking box 2OP. Taxpayers with a TMI of 30% and above should keep the PFU by default. In between, and for contracts over 8 years old, simulation remains essential. The tax authorities, in their guidance (BOFiP-RPPM-RCM-30-10-20-10), emphasise that this option should be exercised with full knowledge of the facts. Take the time to simulate both scenarios before validating your return, and remember to factor in deductible CSG and the impact on your dividends in the calculation.
