Progressive Scale or PFU for Life Insurance: In-Depth Analysis

Choosing between PFU and progressive scale: an underestimated issue

Since the Prelevement Forfaitaire Unique came into effect on 1 January 2018, life insurance gains in France are taxed by default at 12.8% (or 7.5% after 8 years, subject to conditions). Yet the option for the progressive income tax scale, exercised via box 2OP on form 2042, can generate substantial savings for certain taxpayer profiles. The key is knowing when this option is worthwhile and, above all, measuring its effects on the household's overall tax position.

According to data from the Direction Generale des Finances Publiques (DGFiP), approximately 40% of tax households declaring investment income opt for the progressive scale. But many taxpayers tick (or do not tick) box 2OP without fully understanding the consequences. This decision deserves thorough analysis, as it can represent savings -- or additional costs -- of several hundred or even several thousand euros depending on the situation.

How the option works

The option for the progressive scale is:

• Global: it applies to all investment income (dividends, interest, securities capital gains, life insurance gains)
• Annual: it is renewed each year when filing the tax return
• Irrevocable for the year: once the tax return is definitively validated, it is no longer possible to revert to the PFU for that year

The 2026 progressive income tax scale (2024 income)

The applicable scale is as follows:

• Up to 11 497 euros: 0%
• From 11 498 to 29 315 euros: 11%
• From 29 316 to 83 823 euros: 30%
• From 83 824 to 180 294 euros: 41%
• Above 180 294 euros: 45%

These brackets apply to taxable income per share of the household quotient. They determine the TMI (tranche marginale d'imposition), which is the rate applied to the last euro earned.

Profiles for which the progressive scale is advantageous

TMI at 0%: the progressive scale always wins

Non-taxable taxpayers (income below the tax threshold) should always opt for the progressive scale. Tax on gains will be 0% instead of 12.8% (or 7.5% after 8 years).

TMI at 11%: the progressive scale generally wins before 8 years

For taxpayers with an 11% TMI, the progressive scale is advantageous for contracts under 8 years old (11% < 12.8%). For contracts over 8 years old, the PFU at 7.5% regains the advantage, unless deductible CSG and any dividends benefiting from the 40% allowance tip the balance.

TMI at 30% or above: the PFU is almost always preferable

With a 30% TMI, the tax rate far exceeds the PFU at 12.8%. Even factoring in deductible CSG, the PFU remains more advantageous in the vast majority of cases.

The key role of deductible CSG

How deductible CSG works

By opting for the progressive scale, 6.8% of the CSG paid on life insurance gains (and more broadly on investment income) becomes deductible from taxable income the following year (Article 154 quinquies of the CGI). Under the PFU, no portion of the CSG is deductible.

This mechanism is often overlooked in PFU vs progressive scale comparisons, yet it can tip the decision for taxpayers whose TMI is close to the break-even point.

The numerical impact of deductible CSG

For gains of 10 000 euros:

• Deductible CSG: 10 000 x 6.8% = 680 euros
• Tax saving at 11% TMI: 680 x 11% = 74.80 euros
• Tax saving at 30% TMI: 680 x 30% = 204 euros

Paradoxically, deductible CSG benefits higher-TMI taxpayers more in absolute terms. But even at a 30% TMI, it is not enough to offset the gap with the PFU: on 10 000 euros of gains, the extra cost of the progressive scale at 30% is (30% - 12.8%) x 10 000 = 1 720 euros, far from being offset by 204 euros of deductible CSG.

The trap of the option's globality

The option applies to all investment income

The progressive scale choice cannot be selective. If a taxpayer opts for the progressive scale on their life insurance gains, the choice also applies to their:

• Share dividends (which do benefit from the 40% allowance under the progressive scale)
• Interest from term deposits or taxable savings accounts
• Capital gains on securities disposals

This globality is a frequent trap. A taxpayer may gain on their life insurance gains by switching to the progressive scale but lose more on their other investment income. The balance must be calculated across all income.

High-risk situation: diversified investment income

Example: Monsieur Lambert (11% TMI) receives:

• 3 000 euros of life insurance gains (contract < 8 years)
• 8 000 euros of share dividends

Under global PFU:

• Income tax on life insurance gains: 3 000 x 12.8% = 384 euros
• Income tax on dividends: 8 000 x 12.8% = 1 024 euros
• Total income tax: 1 408 euros

Under global progressive scale:

• Income tax on life insurance gains: 3 000 x 11% = 330 euros
• Income tax on dividends (after 40% allowance): 4 800 x 11% = 528 euros
• Total income tax: 858 euros

Here the progressive scale option is clearly advantageous thanks to the 40% allowance on dividends. The saving is 550 euros. This calculation illustrates the importance of considering all investment income together, not just life insurance gains.

The reverse situation: when dividends tip the balance

Example: Madame Mercier (30% TMI) receives:

• 2 000 euros of life insurance gains (contract < 8 years)
• 3 000 euros of share dividends

Under global PFU:

• Income tax: (2 000 + 3 000) x 12.8% = 640 euros

Under global progressive scale:

• Income tax on life insurance gains: 2 000 x 30% = 600 euros
• Income tax on dividends (after 40% allowance): 1 800 x 30% = 540 euros
• Total income tax: 1 140 euros

The PFU is clearly more advantageous here: 500 euros in savings. At a 30% TMI, even the 40% allowance on dividends is not enough to make the progressive scale competitive.

Detailed worked examples: when to switch to the progressive scale

Case 1: the low-income retiree

Madame Renaud, a widow, receives a pension of 14 000 euros per year. She withdraws 6 000 euros of gains from a contract over 8 years old.

Taxable income with life insurance gains under the progressive scale: 14 000 + 6 000 - 4 600 (8-year allowance) = 15 400 euros. TMI: 11%.

• PFU: (6 000 - 4 600) x 7.5% = 105 euros income tax
• Progressive scale: (6 000 - 4 600) x 11% = 154 euros income tax

Here the PFU at 7.5% is more advantageous despite the 11% TMI. The gap is 49 euros in favour of the PFU. However, if Madame Renaud also received dividends, the calculation could reverse thanks to the 40% allowance.

If Madame Renaud's gains had not exceeded the 4 600 euro allowance, both options would be equivalent (0 euros income tax in both cases).

Case 2: the young worker with a recent contract

Monsieur Garcia, single, taxable income of 16 000 euros (11% TMI). He withdraws 2 000 euros of gains from a 3-year-old contract. No other investment income.

• PFU: 2 000 x 12.8% = 256 euros income tax
• Progressive scale: 2 000 x 11% = 220 euros income tax

Saving with the progressive scale: 36 euros, plus deductible CSG of 2 000 x 6.8% = 136 euros, generating 136 x 11% = 14.96 euros extra the following year. Total: 50.96 euros in savings.

Modest in absolute terms, but systematic for this profile. Over 10 years of similar withdrawals, the cumulative saving would reach approximately 500 euros.

Case 3: the couple with significant investment income

Monsieur and Madame Fabre (30% TMI) receive 15 000 euros in dividends and 5 000 euros of life insurance gains (contract < 8 years).

Global PFU:

• Income tax: (15 000 + 5 000) x 12.8% = 2 560 euros

Global progressive scale:

• Taxable dividends (after 40% allowance): 9 000 euros
• Income tax: (9 000 + 5 000) x 30% = 4 200 euros

The PFU is clearly more advantageous here: 1 640 euros in savings. At a 30% TMI, the 40% allowance on dividends does not compensate for the rate differential.

Case 4: the non-taxable taxpayer with a contract over 8 years old

Madame Picard, a retired widow, taxable income of 9 000 euros (0% TMI). She makes a withdrawal generating 8 000 euros of gains from a contract over 8 years old.

PFU:

• Allowance: 4 600 euros
• Income tax: (8 000 - 4 600) x 7.5% = 255 euros

Progressive scale:

• Allowance: 4 600 euros
• Taxable income: 9 000 + 3 400 = 12 400 euros
• First bracket (11%): (12 400 - 11 497) x 11% = 99.33 euros additional income tax
• Total income tax on life insurance gains: approximately 99 euros

The progressive scale wins here: 156 euros in savings. For taxpayers close to the non-taxable threshold, the progressive scale remains advantageous even after 8 years.

How to simulate the right choice

Using the impots.gouv.fr simulator

The tax authority website allows you to compare both options by running two successive simulations:

1. Fill in the return without ticking box 2OP (PFU by default)
2. Fill in the same return ticking box 2OP (progressive scale)
3. Compare the calculated tax amounts
4. Remember to factor in the effect of deductible CSG for the following year

Information to gather

To run the simulation, prepare:

• Your overall taxable income (salaries, pensions, property income, etc.)
• The amount of life insurance gains (shown on the IFU sent by the insurer)
• Your other investment income (dividends, interest, securities capital gains)
• Your family situation (number of household quotient shares)
• The amount of deductible CSG from the previous year if you opted for the progressive scale

Summary: complete decision grid

The progressive scale option is a tax lever often overlooked by savers. For low-income taxpayers (TMI 0% or 11%) or those receiving dividends eligible for the 40% allowance, it can significantly reduce the tax burden. The golden rule remains simulation, as each situation is unique and the global nature of the option requires reasoning across all investment income of the household. Each year at tax filing time, take a few minutes to compare both options: a brief calculation can save you several hundred euros.
