Public Innovation Grants France 2026: Complete Guide to BPI, France 2030, EU Funding and Tax Credits

Updated 15 May 2026. Written by Samuel Hayot, chartered accountant in Paris. This article is for information purposes only; each situation requires a personalised analysis taking your documents, sector, and applicable law into account.

The landscape of public innovation funding has been deeply reshaped since 2022. France 2030 injected 54 billion euros of public credits over eight years, the Horizon Europe programme mobilises 95 billion euros at European level through 2027, and new tax credits - notably the C3IV for green industry - have expanded the range of available instruments.

For the CEO of a startup, an innovative SME, or an industrial company, the real challenge is not knowing every scheme in detail, but understanding which to activate first, in what order, and with what cumulation risks.

This guide offers a practitioner's reading: what we see in client files, where founders lose time, which combinations work, and what traps to avoid.

France 2030: 54 Billion Euros Over Eight Years#

The France 2030 plan, announced in October 2021, structures public investment around ten sectoral objectives: green hydrogen, civil nuclear, health and biotech, clean mobility, agro-ecology, space, digital, defence, culture, and education. Credits are deployed through BPI France, ADEME, and ANR via thematic calls for projects published on the government France 2030 platform.

The timeline is tight: calls for projects have strict closing dates, juries demand technological maturity (TRL), and conventions take three to six months to sign after selection. Planning at least one year ahead is a minimum rule.

Horizon Europe: 95 Billion Euros From the EU#

Horizon Europe is the EU framework programme for research and innovation funding for 2021-2027. It is organised around three pillars: fundamental research (European Research Council), global challenges and European industrial competitiveness, and innovative Europe (EIC). For a French SME, the most accessible instruments are the EIC Accelerator and Horizon consortium projects as an SME partner.

The European Green Deal as a Filter#

Since 2023, a growing share of public funding - European and national alike - is conditioned on a contribution to the Green Deal: decarbonisation, energy efficiency, circular economy. Ignoring this dimension in an application is a negative signal for evaluation juries.

Tax credits are the first instruments to activate because they are a statutory right: there is no jury, no competitive selection, and amounts can be substantial. They generally combine well with direct grants, subject to deduction rules.

Our reading. The CIR remains the most powerful tool for companies with significant R&D payroll expenses. The CII is often underused by SMEs that innovate without conducting fundamental research in the strict sense. The C3IV entered into force recently and deserves specific examination for any company in the batteries, heat pumps, wind, or solar panels sectors.

BPI France is the central operator of public innovation funding in France. Its range covers every stage of an innovative company's life.

French Tech Grant (30,000 to 50,000 euros)#

Aimed at startups in the ideation or proof-of-concept phase. It is a non-refundable subsidy awarded after selection by a regional jury. The file focuses on team strength, market relevance, and technological credibility. Average delay from submission to payment: four to six months.

Feasibility Aid (up to 50,000 euros)#

A grant covering technical or commercial feasibility studies prior to an innovation project. Less well known than the French Tech Grant, it is more accessible because the project does not need to be finalised. It often serves as the first aid received before an Innovation Loan.

Innovation Loan (50,000 to 500,000 euros)#

A reduced-rate loan (between 0 and 2% depending on conditions) with no personal guarantee, targeting SMEs with a clearly identified innovation project. Often used alongside equity investment or a fundraising round. The file requires a detailed business plan, a coherent financing plan, and a credible technical roadmap.

Seed Loan (100,000 to 500,000 euros)#

A product close to the Innovation Loan but aimed at very upstream projects still in the seed phase. It can be combined with conventional bank loans in the context of a structured financing plan.

BPI Innovation Guarantee (up to 70% of bank debt)#

BPI France can guarantee up to 70% of a bank loan granted to an innovative company, allowing the bank to reduce its risk and the founder to limit their personal guarantee. This instrument is particularly useful for companies with no tangible assets to pledge.

i-Lab Competition (20,000 euros + mentoring)#

The i-Lab Competition funds high-technology startup creation projects. The laureate receives financial support and mentoring from a BPI tutor. Selectivity is high and the jury values deeptech projects.

Deeptech Plan: Labelling and Support#

The BPI France Deeptech label provides access to a dedicated financing ecosystem: French Tech Seed fund, access to specialised investors, and technical and commercial support. The process takes six to twelve months but opens doors that are otherwise inaccessible.

France 2030 is not an open window: it is a set of calls for projects published in waves, each with its own eligibility criteria and jury. Themes include:

• Energy: innovative nuclear reactors, hydrogen, storage
• Health and biotechnologies: biotech, medtech, diagnostics
• Clean mobility: electric vehicles, rail, low-carbon aviation
• Digital: sovereign cloud, cybersecurity, artificial intelligence
• Agro-ecology: sustainable agriculture, food
• Green industry: decarbonisation of industrial sites

Files are submitted on demarches.data.gouv.fr or directly to BPI France, ADEME, or ANR depending on the programme. Average ticket ranges from 200,000 euros for experimentation projects to several million for advanced industrial projects.

The underestimated risk. Project leaders systematically underestimate the preparation time for a France 2030 file: between two and four months for a solid submission, with mobilisation of a research partner for technical projects. Carefully reading the terms of reference before any commitment of time or resources is essential.

Regional councils and metropolitan authorities have their own innovation aid envelopes, often less well known but faster to obtain.

Ile-de-France. The IDF Region deploys approximately 100 million euros per year in support for innovative companies, via grants, repayable advances, and participations in regional funds. Paris Region Entreprises is the natural entry point.

Other major regions. Auvergne-Rhone-Alpes, Hauts-de-France, and Nouvelle-Aquitaine have specific programmes for innovative companies, often articulated with FEDER funds and national schemes.

Metropolitan areas. Grand Paris, Metropole de Lyon, Bordeaux Metropole, and Marseille Provence Metropole have direct aid programmes for startups and innovative SMEs, often as payroll or equipment subsidies.

ADEME (the French Agency for Ecological Transition) finances the ecological transition of companies through several schemes:

• Diag Eco-Flux: free or subsidised diagnostic of energy and material consumption, the entry point to more substantial grants.
• Investment aids: subsidies or repayable advances for emissions reduction, energy efficiency, or circular economy projects.
• Green Industry Ecological Bonus: complement to the C3IV for industrialists investing in certified low-carbon equipment.

ADEME generally requires co-instruction with BPI France for large-scale projects under France 2030.

EIC Accelerator (1 to 15 million euros)#

The EIC Accelerator is the most generous European scheme for innovative SMEs: up to 2.5 million euros in grant combined with up to 15 million euros in EIC Fund equity investment. Eligibility targets breakthrough innovations with strong European and global market potential. The success rate is low - under 5% - but preparing an EIC file is a structuring exercise useful regardless of the outcome.

EIC Pathfinder (upstream research)#

Aimed at research consortia exploring radically new technologies. Less accessible for a standalone SME, but relevant for university-company partnerships.

FEDER: European Regional Development Fund#

FEDER co-finances projects in eligible regions. In France, FEDER credits are managed by Regional Councils and can fund R&D investment, digital infrastructure, or energy transition. Instruction is local but cumulation and reporting rules are European.

For innovative companies targeting international markets:

• BPI Export Credit and Export Guarantee: facilitates access to bank financing for export projects and guarantees non-payment risk from foreign clients.
• Business France VIE (International Corporate Volunteer): enables sending a young professional abroad with partial State support. The real cost to the company is often lower than that of a conventional expatriate.
• Regional Export Grants: regions subsidise participation in international trade fairs, commercial missions, and export market studies.

Hiring Aids#

• Young people under 26: hiring aid under current schemes (to verify with France Travail for the current year).
• People with disabilities: AGEFIPH, workstation adaptation aid.
• Seniors over 55: senior professionalisation contract, hiring aid under the applicable scheme.

Training via OPCO#

Companies with fewer than 50 employees can mobilise their OPCO (Skills Operator) to finance training without drawing on their payroll budget. The management training tax credit is a useful complement for the director.

ACRE, NACRE, ARCE, Honour Loan#

• ACRE: partial or total exemption from social contributions in the first year of activity, filed with URSSAF within 45 days of company creation.
• NACRE: free support by an accredited operator for three years.
• ARCE (France Travail): payment as capital of a portion of remaining unemployment rights, for insured company founders.
• Honour Loan (Reseau Entreprendre, Initiative France): personal loan with no interest or guarantee, from 5,000 to 50,000 euros, awarded after selection by a jury of volunteer business leaders.

The de minimis rule caps State aid not subject to notification to the European Commission at 200,000 euros over three rolling fiscal years (300,000 euros in certain sectors since Regulation 2023/2831). Beyond this, aids must be granted under a notified and approved regime.

In practice. A founder who combines a French Tech Grant, a regional subsidy, ADEME aid, and a subsidised loan may approach the limit without realising it. The chartered accountant must maintain a tracking table of aids received and verify the qualification of each (de minimis or notified regime) before submitting a new application.

Deducting grants from the CIR base is another frequent source of error: a non-refundable grant received for an R&D project must be deducted from eligible expenses; otherwise the tax credit is overstated and the company faces a reassessment.

1. Eligibility check: read the terms of reference or the regulatory text. Do not apply if criteria are not met.
2. File preparation: business plan, financing plan, technical project description, team CVs, quotes, or detailed budgets.
3. Submission: on the dedicated platform (BPI Connect, demarches.data.gouv.fr, or the EIC European portal).
4. Review and jury: two to six months depending on the scheme. Additional questions may be asked by the reviewer.
5. Convention: signing of a convention defining milestones, required supporting documents, and payment conditions.
6. Monitoring and justification: progress reports, accounting documents, technical accounts. The chartered accountant intervenes for compliance of supporting documents.
7. Balance and audit: payment of the balance after verification of outcomes. An audit may be conducted by the funder.

Case 1: Deeptech Startup Paris, Pre-Seed#

A two-founder startup spun out of Ecole Polytechnique is developing a quantum sensor for industrial gas detection. It has just incorporated as a SAS and has no revenue yet.

Actionable public funding within 12 months:

• French Tech Grant: 30,000 euros to fund first prototypes.
• BPI Seed Loan: 200,000 euros to secure 18 months of runway without dilution.
• CIR: estimated base of 300,000 euros in R&D expenses (founder researcher salaries and laboratory services), giving a tax credit of 90,000 euros refundable from year one as a JEI.
• BPI Deeptech Label: support pathway and access to French Tech Seed fund.

Total mobilisable public funding: approximately 320,000 euros without dilution, before a fundraising round.

Case 2: Green Industrial Company, Hauts-de-France, Battery Production#

An 80-employee SME in the Lille region wants to invest 5 million euros in a battery production line for electric vehicles.

Potential public financing plan:

• C3IV: 20 to 40% of eligible cost depending on company size and location (AFR zone possible), representing 1 to 2 million euros in tax credit.
• France 2030 - Green Industry: dedicated call for projects, potential grant of 500,000 to 1.5 million euros subject to jury approval.
• ADEME: investment aid for the energy efficiency of the production line.
• BPI Green Growth Loan: supplementary financing for the uncovered portion.
• FEDER Hauts-de-France: possible European co-financing subject to regional eligibility.

Such a file requires careful coordination between the accounting firm, the regional BPI advisor, and possibly a State aid specialist consultant.

Case 3: Export SME, Nouvelle-Aquitaine#

A 30-employee Bordeaux SME in the vineyard equipment sector wants to open a commercial office in Spain and prospect the Japanese market.

Actions to take:

• VIE Business France: deploying a young professional to Spain for 12 to 24 months, with partial State funding via Business France.
• BPI Export Guarantee: cover for non-payment risk from foreign clients.
• Nouvelle-Aquitaine Regional Export Aid: subsidy for participation in the Vinitech-Sifel trade fair and a commercial mission to Japan.
• BPI Export Credit: financing of the export receivable if payment terms are long.

In the files we advise on in Paris, three mistakes recur systematically.

1. Activating grants in the wrong order. Tax credits (CIR, CII, C3IV) must be calculated before submitting grant applications, because the non-refundable grant must be deducted from the eligible base. Reversing the order leads to an overstated tax credit, exposing the company to reassessment during a tax audit.

2. Ignoring the de minimis rule. No tracking is maintained, and the company discovers during an audit that it exceeded the three-year cap. The consequence can be the recovery of illegally cumulated aids, with interest.

3. Underdocumenting the project. A poorly documented BPI or France 2030 file - inconsistent project timeline, untraceable expenses, no milestones - fails at the jury stage or is reassessed at balance. Accounting rigour is a competitive advantage in a call for projects.

Our role is not to replace an innovation consultant or a BPI business advisor, but to secure the foundations: exact tax credit calculation, tracking of aids received, coherence of the financing plan, and preparation of supporting documents for balance payment. This upstream work prevents costly reassessments and maximises the effective refund rate.

• Identify the project maturity stage (TRL, revenue, headcount)
• Calculate CIR/CII/C3IV base before any grant application
• Verify JEI eligibility for startups under 8 years old
• List all aids received over the last three fiscal years (de minimis rule)
• Check the current France 2030 calls for projects calendar
• Verify regional eligibility before targeting FEDER funds
• Prepare a coherent technical and financial file before submission
• Set up accounting tracking of eligible expenses by project
• Anticipate supporting documents required at balance (invoices, payslips, R&D timesheets)
• Have the financing plan reviewed by your chartered accountant before signing the convention
