France's 2026 Employer Payroll Relief Reform: What Changes for Employers

The overhaul of employer social contribution relief on 1 January 2026 is the most structurally significant change since the Fillon reduction was introduced in 2003. After years of accumulated, overlapping mechanisms — the general degressive reduction, the reduced sickness band and the reduced family allowance band — the legislature merged them all into a single scheme. For employers running small and medium-sized businesses, the stakes are immediate: the January 2026 payroll requires a new formula, new parameters and heightened attention to the reference minimum wage (SMIC).

This article sets out the applicable rules, the official formula, the current parameters and the operational points of vigilance we observe in the payroll files of our clients.

From 1 January 2026, the two reduced-rate salary bands (sickness contribution up to 2.5× SMIC, family allowances up to 3.5× SMIC) were abolished and merged into a single degressive employer relief (RGDU — réduction générale dégressive unique) applicable up to 3× the SMIC. The maximum coefficient is 0.3981 for employers with fewer than 50 employees (0.4021 for 50 employees or more). The relief falls to zero the moment annual gross pay reaches or exceeds three times the annual SMIC.

Until 31 December 2025, three mechanisms coexisted to reduce employer social contributions on lower wages:

1. The general degressive reduction (the "Fillon reduction"), applicable up to 1.6× the SMIC.
2. A reduced sickness contribution rate (13% reduced to 7%), applicable between 1× and 2.5× SMIC.
3. A reduced family allowance contribution rate (5.25% reduced to 3.45%), applicable between 1× and 3.5× SMIC.

Law n° 2025-199 of 28 February 2025 (Social Security Financing Act — LFSS 2025, Article 18), supplemented by Decree n° 2025-887 of 4 September 2025, abolished all three layers and replaced them with a single mechanism: the RGDU. The simplification is genuine, but it reshuffles the cards for many employers whose staff were earning between 1.6× and 3.5× SMIC.

Yes, without exception for mainstream private-sector employers. The reduced sickness contribution rate (7% instead of 13%) and the reduced family allowance rate (3.45% instead of 5.25%) disappeared from the general social security regime on 1 January 2026.

One important nuance: these reduced rates survive only for employers benefiting from specific territorial or sectoral exemptions (Lodeom for overseas departments, TO-DE for seasonal agricultural work, AADPA, ZRD, ZFRR). For the vast majority of standard TPE and PME employers, they no longer exist.

This is the most visible structural change. The old Fillon general reduction expired at 1.6× the annual SMIC. The RGDU 2026 runs to 3× the annual SMIC. The relief becomes zero exactly when annual gross pay reaches that threshold.

With the SMIC in force on 1 January 2026 (€1,823.03/month), the exit threshold from the relief sits at approximately €65,629 gross per year (around €5,469 gross per month for a full-time employee). That threshold will shift when the SMIC is revised upward.

Our reading: for an employer whose team includes technicians or junior sales staff earning between €2,000 and €4,000 gross per month, the RGDU 2026 unlocks an entitlement to relief in salary ranges where previously only the family allowance band applied — and only partially. The potential saving is worth a precise calculation before drawing any conclusions.

The official formula, derived from Decree n° 2025-887, is as follows:

Coefficient = Tmin + (Tdelta × [0.5 × (3 × annual SMIC / annual gross pay − 1)]^P)

The parameters are:

The coefficient is capped at its maximum value at SMIC level and falls to zero once pay reaches 3× SMIC.

Maximum coefficients (at SMIC level)#

The relief amount equals: Gross pay × Coefficient

Illustrative example#

An employee earns €2,200 gross per month in a 12-person business. Based on the SMIC in force in January 2026 (€1,823.03/month, or €21,876.36 annually), the reference annual gross pay would be €26,400.

The ratio 3 × SMIC / pay would be approximately €65,629 / €26,400 ≈ 2.49. The bracketed term equals 0.5 × (2.49 − 1) = 0.745. Raised to the power 1.75, that term gives approximately 0.574. The approximate coefficient would therefore be: 0.0200 + 0.3781 × 0.574 ≈ 0.237, producing an approximate monthly relief of €2,200 × 0.237 ≈ €521.

This calculation is purely illustrative. The exact coefficient must be obtained via the official URSSAF simulator (urssaf.fr). Actual parameters — working hours, pay components taken into account — can materially alter the result.

This is where errors occur most frequently, and it is the point we monitor as a priority in the payroll files we manage.

The SMIC to use is the rate in force for the relevant employment period — not a fixed annual value frozen at the start of the year. The formula incorporates an "annual SMIC" which is derived from the SMIC applicable over each pay period, adjusted for the employee's actual or contractual working hours.

In 2026, two SMIC values apply:

• From 1 January to 31 May 2026: €12.02/hour, or €1,823.03/month for a full-time 35-hour week.
• From 1 June 2026 onward: €12.31/hour, or €1,867.02/month for a full-time 35-hour week.

This June uprating mechanically alters the reference "annual SMIC" used in the formula for payslips issued from June 2026 onward. An employee whose pay sits close to the 3× SMIC threshold may therefore see their position shift slightly from one half of the year to the other.

The underestimated risk: certain payroll software packages configured with a fixed annual SMIC set at the start of the year may produce incorrect coefficients from June 2026 onward. Verify that your payroll tool automatically incorporates the updated reference SMIC. See also our guide on SMIC 2026.

The table below schematically compares the old regime (until 31 December 2025) and the new regime (from 1 January 2026) to illustrate the areas of gain and loss.

Before and after 2026 comparison by pay band#

Our reading: the 3× to 3.5× SMIC band is the only zone where an employer can suffer a net loss relative to 2025. This typically affects employees earning between €5,469 and €6,381 gross per month. This segment deserves careful scrutiny of the payroll budget before the end of the first half of the year.

The RGDU applies to all private-sector employers affiliated to the general French social security regime, except those operating under a specific incompatible exemption scheme (Lodeom, TO-DE, etc.). It therefore covers:

• Companies (SARL, SAS, SA, SNC, etc.)
• Sole traders employing staff
• Non-profit associations (loi 1901) with employees
• Employer groupings

Self-employed workers, corporate officers without an employment contract, and professionals in private practice with no payroll are not in scope.

The calculation base for the RGDU is annual gross pay subject to social security contributions, as used for employer contribution calculations. In practice, this includes:

1. Basic salary
2. Bonuses and gratuities subject to contributions
3. Benefits in kind subject to contributions
4. Regular salary supplements

Pay components exempt from contributions (profit-sharing and incentive schemes within certain limits, meal vouchers, etc.) are excluded from this base. For a detailed picture of what appears on the payslip, see the new 2026 payslip format and the 2026 net social amount.

The RGDU may be calculated under two methods, as was the case for the former Fillon reduction: monthly calculation (the most common approach), or annual calculation with regularisation at year-end or on the employee's final payslip of the year. Annual regularisation is mandatory in certain configurations (short fixed-term contracts, mid-year starters and leavers, changes in working hours).

When the SMIC is revised mid-year — as happens on 1 June 2026 — the annual regularisation may generate material differences between monthly advances and the final balance. This is a control point to anticipate as part of your payroll outsourcing.

In the opening months of 2026, we identified three recurring friction points when reviewing payroll:

First point: payroll software not yet updated that continues to apply the Fillon ceiling at 1.6× SMIC, leaving part of the relief unclaimed for employees earning between 1.6× and 3× SMIC. The missed relief is not lost if a regularisation is carried out in time, but it creates a cash flow timing difference.

Second point: confusion over which FNAL rate applies. An employer who crosses the 50-employee threshold during the year must switch to the Tdelta of 0.3821. That switch affects the coefficient and therefore the relief applied across the whole workforce.

Third point: uncertainty about how the RGDU should appear on the payslip. The reduction line must now reflect the new unified mechanism; the old "bandeau maladie" or "bandeau AF" labels no longer have any place on the payslip.

1. Confirm that your payroll software or provider has correctly loaded the RGDU 2026 parameters (Tmin 0.0200, P 1.75, Tdelta according to headcount, 3× SMIC ceiling).
2. Verify that the reference SMIC is updated automatically from 1 June 2026 (€12.31/hour, €1,867.02/month) and has not been frozen at the January value.
3. Identify employees whose pay falls between 3× and 3.5× annual SMIC: they lose the benefit of the reduced family allowance rate without any offsetting relief under the RGDU.
4. Check your headcount against the 50-employee threshold to determine the correct Tdelta (0.3781 or 0.3821).
5. Ensure that payslips for January through May 2026 no longer carry the old "bandeau maladie" and "bandeau AF" line items.
6. Schedule the annual regularisation if your software calculates the relief on a monthly basis: the differences arising from the June SMIC uprating must be settled no later than the final payslip of the year.

For employers considering a first hire, our guide on hiring your first employee already incorporates these new calculation rules.

Two approaches coexist:

Pure monthly calculation: the coefficient is calculated each month on the basis of that month's SMIC and pay. Easy to manage, but can create irregularities for employees whose pay varies (one-off bonuses, overtime).

Annual regularisation: monthly amounts are treated as provisional advances; a final balance is calculated at year-end on total annual pay and the weighted annual SMIC. More precise for variable pay, but requires coordination between payroll close and the year-end tax return preparation.
