Breakthrough Young Innovative Company (JEIR) France 2026: Conditions and Tax Benefits

Up to date as of 12 May 2026. The Jeune Entreprise Innovante de Rupture (JEIR — Breakthrough Young Innovative Company) is a sub-category of the French JEI (Jeune Entreprise Innovante) tax status, introduced by the French Finance Act 2024 (loi n° 2023-1322 of 29 December 2023, Article 44). Its defining criterion is a higher R&D intensity threshold: at least 30% of fiscally deductible expenses must relate to research and development activities, compared to 15% for the standard JEI. The Finance Act 2024 simultaneously aligned the corporate tax (IS) exemption levels between JEI and JEIR, making the JEIR the more demanding but comparably rewarded option for deeptech and high-intensity R&D companies.

For a Paris-based startup or SME with strong technological content, choosing between JEI and JEIR is a material fiscal decision that affects several years of tax and social security exemptions and requires solid analytical accounting to withstand a combined DGFiP/URSSAF audit.

The JEI regime is codified in Article 44 sexies-0 A of the French General Tax Code (CGI). The Finance Act 2024 (loi n° 2023-1322, Article 44) introduced three key changes:

1. A new sub-category — the JEIR — with an R&D intensity threshold of 30% of deductible expenses.
2. A reduction in the maximum age of eligibility from 11 to 8 years, applicable to financial years opened from 1 January 2024.
3. Alignment of IS exemptions for JEIR with those applicable to the standard JEI.

The JEIR is not a separate article in the CGI; it is distinguished within Article 44 sexies-0 A by the 30% threshold. Tax exemptions are addressed under Article 44 sexies-0 A (IS), Articles 1383 D and 1466 D (land tax and CET), and social contribution exemptions derive from Article 131 of Law n° 2003-1311.

Caveat: As of the update date of this article, the BOFiP (official French tax doctrine) had not yet published detailed administrative guidance specifically on the JEIR as a distinct sub-category under Finance Act 2024. Practitioners should monitor BOFiP publications and consider a tax ruling (rescrit) before applying the regime.

All five conditions must be met simultaneously. Failing any one of them disqualifies the company from JEIR status.

1. Size criterion: EU-definition SME#

The company must employ fewer than 250 employees AND have annual turnover below or equal to €50 million OR a balance sheet total below or equal to €43 million. These are the thresholds of the EU SME definition (European Commission Recommendation 2003/361/EC). A mid-cap company that exceeds either threshold cannot claim JEIR status regardless of R&D intensity.

2. Age criterion: less than 8 years (Finance Act 2024 change)#

The company must be less than 8 years old on 1 January of the tax year. Finance Act 2024 reduced this limit from 11 to 8 years. Companies created in 2018 reaching their 8-year mark in 2026 must check whether they remain eligible based on the exact opening date of their financial year.

3. Capital independence criterion#

At least 50% of the capital and voting rights must be held, directly or indirectly, by: natural persons, other JEI-status companies, publicly recognised scientific research foundations or associations, public research bodies, or eligible venture capital vehicles (French FCPI or FIP funds). This criterion is designed to exclude subsidiaries of established industrial groups. Any investment round admitting non-eligible institutional investors risks pushing eligible ownership below 50%.

4. Genuine creation criterion#

The company must be genuinely newly created — not resulting from a merger, restructuring, extension of a pre-existing activity, or takeover of an activity previously carried out by another business. DGFiP controls this criterion: a spin-off that absorbs assets or teams from an existing entity may be requalified.

5. R&D intensity criterion: >= 30% of deductible expenses (JEIR threshold)#

This is the distinguishing criterion. R&D expenditure — as defined in Article 244 quater B of the CGI (same scope as the Research Tax Credit) — must represent at least 30% of total fiscally deductible expenses for the year. Eligible categories include: depreciation on R&D-dedicated assets, R&D personnel costs (researchers, technicians), R&D project managers' remuneration, patent filing and defence costs, R&D sub-contracting with approved public or private bodies, and provisions for depreciation of R&D-derived product inventories.

Our view: The 30% threshold requires robust analytical accounting and rigorous time-tracking. In the client files we handle at Hayot Expertise in Paris, deeptech startups (AI, biotech, medtech, semiconductors) naturally reach this level. Conventional SaaS companies with lean R&D teams typically track between 20-25%, making the standard JEI a better fit.

Corporate tax (IS) exemptions#

Finance Act 2024 aligned IS exemptions between JEI and JEIR:

• First profitable financial year: 100% IS exemption.
• Second profitable financial year: 50% IS exemption.
• From the third profitable year onwards: standard IS regime.

A loss-making year does not "consume" the exemption but does not carry it forward. The exemption is calculated on taxable profit before imputation of tax credits (CIR, CII). BOFiP confirmation pending on the exact mechanics for JEIR as a distinct sub-category.

Local economic contribution exemption (CET: CFE + CVAE)#

Article 1466 D CGI allows local authorities to pass a resolution granting a CFE and CVAE exemption for up to 7 years. This is not automatic: it requires an explicit local authority resolution. Paris-based companies should verify whether the relevant municipality has adopted such a resolution and under what conditions.

Land tax exemption#

Article 1383 D CGI provides an equivalent option for land tax on built properties. Again subject to local authority resolution. Relevant primarily for companies that own their laboratory premises; tenant companies in Paris are not directly affected.

Scope of the exemption#

The JEIR exemption covers employer social security contributions for employees and executives assigned to R&D work. Eligible roles: researchers, R&D technicians, R&D project managers, intellectual property lawyers handling patent filings and technology transfer agreements, and executive directors who directly and predominantly work on R&D. The exemption applies to the employer share of contributions for sickness, maternity, disability, death, old-age, family allowances and work accident/occupational disease.

De minimis ceiling: €200,000 over 3 rolling years#

All financial advantages of the JEIR regime — employer contribution exemptions, CET and land tax exemptions combined — are subject to the EU de minimis aid ceiling of €200,000 over three rolling fiscal years (EC Regulation n° 1407/2013). This ceiling aggregates all de minimis aid received by the company from any source. Exceeding it triggers repayment of the excess, potentially retroactively.

In practice: for a deeptech startup of 5 to 10 employees with 3 or 4 assigned to R&D, annual employer contribution exemptions typically range from €15,000 to €35,000 depending on salary levels. The €200,000 ceiling is generally reached around year 4 or 5 as the R&D team grows. Tracking this ceiling consolidated across all aid sources is a monitoring task Hayot Expertise integrates into annual JEIR client reviews.

CIR compatibility#

JEIR status is fully compatible with the Research Tax Credit (CIR — CGI Article 244 quater B). Both mechanisms may benefit the same R&D expenses but operate through distinct calculations. The CIR reduces IS or generates a refundable tax receivable; JEIR IS exemptions apply upstream before net IS is determined. Poor documentation exposes both the CIR and the JEIR status to simultaneous reassessment.

CII compatibility#

The Innovation Tax Credit (CII — CGI Article 244 quater B, II) is similarly compatible. The distinction between CIR-eligible expenses (fundamental research, applied research, experimental development) and CII-eligible expenses (product innovation) must be rigorously documented to avoid double-counting.

Bpifrance: French Tech Grant and Innovation Aid#

JEIR status is a facilitating (though not sufficient) factor for Bpifrance instruments: Bourse French Tech, Aide Individualisee a l'Innovation (AI), and innovation loans. Not all Bpifrance instruments are de minimis aids in the technical EU sense (repayable loans are debt instruments). Each instrument's classification should be verified when building a financing package.

The underestimated risk: combined DGFiP / URSSAF audit#

DGFiP and URSSAF share information on JEI/JEIR status. An URSSAF payroll audit that challenges the employer contribution exemptions can trigger a DGFiP referral that reopens IS exemptions. The resulting double reassessment is the most significant risk in this area and one that is frequently underestimated by startup founders. Analytical accounting for R&D must simultaneously satisfy both administrations' documentation requirements.

Most frequent audit findings#

• Insufficient R&D documentation: no laboratory notebooks, no signed time-sheets by project, no progress reports.
• Improper staff classification: sales or support staff wrongly allocated to R&D roles to inflate the R&D expense base.
• Capital independence breach: non-eligible investor entry that pushes eligible ownership below 50%.
• Genuine creation challenge: subsidiary created to restart a JEI clock on an existing activity.
• De minimis ceiling breach: multiple aid sources not consolidated in a single tracking register.

Situation: SAS incorporated in Paris in 2022, 5 employees (3 R&D engineers, 1 sales, 1 technical CEO), 2025 turnover €380,000, balance sheet total €520,000. Fiscally deductible expenses 2025: €640,000, of which €385,000 are R&D expenses per analytical accounts (60% ratio). Capital: 75% held by the two founders (natural persons), 25% by an approved FCPI.

JEIR analysis:

• SME: yes (< 250 employees, turnover < €50M, balance sheet < €43M)
• Age: created 2022, 2025 = year 3. Well within the 8-year limit.
• Capital independence: 75% natural persons + 25% FCPI = 100% eligible holders. Criterion satisfied.
• Genuine creation: incorporated ex nihilo, no activity takeover.
• R&D intensity: 60% > 30%. JEIR criterion satisfied.

Conclusion: the company qualifies as JEIR for financial year 2025. If 2025 is the first profitable year, the IS exemption is 100%. Employer contribution exemptions on the 3 R&D engineers represent approximately €18,000 for the year. CIR stacking on the same R&D base is to be processed separately via Form 2069-A.

Recommended approach by Hayot Expertise: formalise analytical R&D accounting, prepare a tax ruling application before the first JEIR declaration, and calculate the consolidated de minimis ceiling (JEIR exemptions + refundable CIR + any Bpifrance grants).

1. Reaching the 8-year age limit: the expected "normal" exit. Plan for this 12 to 18 months in advance to adapt the financing plan and identify replacement mechanisms (CIR, CII, enterprise zones if applicable).
2. Loss of capital independence: any funding round admitting a non-eligible investor must be checked against the 50% threshold before signing. This requires coordination between the M&A lawyer and the accountant — a process cabinet Hayot Expertise supports for its Paris-based clients.
3. R&D intensity falling below 30%: as the company scales and operational and commercial costs grow faster than the R&D envelope, the ratio may fall below the JEIR threshold. The company may then qualify for standard JEI (>= 15%) if that lower threshold is still met.

A successful JEIR file is not built in a single month. Our recommended operating cadence covers four quarterly reviews and one annual close, embedding the JEIR requirements in the normal accounting calendar.

Quarter 1: framing and analytical accounting setup#

In the first quarter of the financial year, the team formalises the R&D project portfolio, opens dedicated analytical sections for each project, and parametrises the time-tracking tool (we typically use a simple spreadsheet or a SaaS such as Toggl for early-stage companies, with custom fields for project, phase and CIR-eligibility flag). The chart of accounts is reviewed to ensure that R&D-related expense accounts (614x, 615x, 622x for research subcontracting, 641x for R&D headcount) are correctly mapped.

Quarter 2: mid-year R&D intensity check#

By the end of the second quarter, the company computes a provisional R&D intensity ratio based on year-to-date expenses. If the ratio is trending below 30%, the management team has six months to take corrective action: accelerating R&D hiring, reclassifying genuinely mixed roles, or deferring non-R&D spend. Below 30%, the company may have to fall back to the standard JEI threshold of 15%, which is still attractive but significantly less ambitious.

Quarter 3: pre-closing tax positioning#

The third quarter is the right moment to discuss with the chartered accountant whether the company will be in profit at year-end, since the IS exemption applies only on profitable years. If a loss is anticipated, the JEIR IS exemption is preserved for future use (the first profitable year carries the 100% exemption). If a profit is anticipated, the practical interaction with the CIR refund must be modelled in detail.

Quarter 4: annual close and de minimis consolidation#

At year-end, the team consolidates: (i) the audited R&D expense base, (ii) the URSSAF and DGFiP exemptions obtained during the year, (iii) any Bpifrance grant treated as de minimis, and (iv) any other public aid received. The cumulative figure is compared with the EUR 200,000 ceiling over three rolling years. If the company is approaching the ceiling, the next year's planning must adjust accordingly.

Annual filing and JEI/JEIR-specific declarations#

The JEIR status itself does not require an annual specific declaration to the DGFiP, but the company indicates the regime in its corporate tax return (form 2065) and in the related schedules. The URSSAF exemptions are activated through the monthly DSN with a dedicated CTP code for JEIR. A mismatch between the IS declaration and the DSN entries is a frequent red flag during audit.

For foreign entrepreneurs considering an incorporation in France, the JEIR regime should be compared with comparable schemes in other jurisdictions to put the French offer in context.

UK R&D tax relief#

The UK SME R&D tax relief, reshaped in 2024, provides an enhanced deduction or a payable credit on qualifying R&D expenditure, with rates updated by the UK Spring Budget. The UK scheme is more focused on cash refund through HMRC than on a parallel social contribution exemption. The French JEIR combination of IS exemption plus payroll exemption plus stackable CIR is structurally more generous in absolute terms when the company has a significant R&D headcount.

US Qualified Small Business Stock (QSBS, Section 1202)#

The US QSBS exemption provides up to 100% exclusion of capital gain on the sale of qualifying small business stock held for more than five years, subject to caps. It is an exit-time benefit rather than an ongoing operating one. For founders comparing jurisdictions, the structural decision is whether to optimise for ongoing cash savings during the build phase (JEIR) or for capital gain treatment at exit (QSBS).

Practical implication for cross-border founders#

A founder considering whether to incorporate in France can frequently combine multiple regimes by having a French operating company (SAS or SASU) eligible for JEIR and CIR, and a parent holding structure abroad that aligns with the founder's personal tax residence. The cross-border structuring requires careful coordination between French and foreign counsel to avoid permanent establishment and transfer pricing issues. Hayot Expertise often works alongside US, UK or Israeli counsel on such structures.

Three operational points consistently arise in JEIR files at Hayot Expertise:

Documentation is the real barrier to entry. Reaching 30% R&D in expenses is not enough without proof. A quarterly R&D analytical dashboard with signed timesheets from assigned staff is the operational minimum.

The tax ruling is not optional for material stakes. A startup anticipating a significant IS exemption (first profitable year) or multi-year payroll contribution exemptions should systematically file a ruling request with the business tax office before declaring JEIR status. Articles L 80 A and L 80 B of the French Tax Procedures Book govern this process. Cabinet Hayot Expertise prepares and files these ruling applications for its Paris clients.

The de minimis ceiling must be tracked on a consolidated basis. Many startups receive aid from multiple sources without aggregating it. An undetected breach exposes the company to retroactive repayment demands across all sources.

A typical 24-month JEIR roadmap for a Paris deeptech startup#

For a deeptech startup incorporated in Paris and planning a Series A round in 18 to 24 months, the typical roadmap looks like this:

• Months 1 to 3: incorporation, capital table verification, R&D project portfolio setup, analytical accounting parameters.
• Months 4 to 6: first quarterly R&D ratio check, tax ruling preparation, first URSSAF DSN with JEIR exemption codes.
• Months 7 to 9: tax ruling filing, mid-year R&D intensity review, Bpifrance instrument scoping.
• Months 10 to 12: annual close, de minimis ceiling consolidation, IS return with JEIR claim if profitable.
• Months 13 to 18: ongoing quarterly monitoring, CIR file preparation for the prior year, fundraising preparation including JEIR status as a value driver in the data room.
• Months 19 to 24: Series A closing with attention to capital independence threshold, post-money structuring to preserve eligibility, alignment of the financing strategy with the eight-year window.
