There is a widespread belief among directors of industrial SMEs: "R&D grants are for large companies with their own laboratory." It is understandable to think so, but it is a costly mistake. Spanish law — and European law — defines innovation far more broadly than most people imagine. Manufacturing a component with a dimensional tolerance that was previously unachievable, adapting a production line to a new material, developing proprietary control software, or improving a welding process that reduces rejects by 30% are activities that technically qualify as R&D or technological innovation. The question is not whether what you do deserves the name of research; the question is whether you know how to document it, classify it, and present it to the authorities in a way that will not get it rejected.
This article explains, step by step, how an industrial SME without an R&D department can access the main grants available in Spain in 2026: tax deductions under Article 35 of the Corporate Income Tax Act, CDTI subsidies, regional calls, and Horizon Europe programmes accessible through consortia. It also explains the role a specialist consultancy plays in doing the work the company cannot do on its own.
What counts as R&D under Spanish regulations
The first obstacle is conceptual. Many companies do not apply for anything because they believe their activities are not sufficiently "scientific." However, Law 27/2014 on Corporate Income Tax distinguishes three categories with different requirements:
| Category | Legal definition | Industrial examples | Tax deduction (gross tax liability) |
|---|---|---|---|
| Research (R) | Original, planned investigation aimed at discovering new knowledge | Development of new alloys, study of material properties | 25% of expenditure (35% if it exceeds the average of the previous 2 years) |
| Development (D) | Application of research results to manufacture new materials, products or procedures | Prototyping of bespoke tooling, design of a mould with a new geometry | 25% of expenditure (35% on the excess over the average) |
| Technological innovation (TI) | Activity whose result is a technological advance in existing products or processes | Integration of a machine-vision system into an existing line, implementation of a proprietary MES | 12% of expenditure |
The most important practical distinction for an industrial SME is that technological innovation does not require generating knowledge that is new at a global level: it is enough for it to be new to the company and to represent an objective technological advance. That puts the 12% deduction within reach of many more companies.

Tax deductions under Article 35 of the Corporate Income Tax Act
This is the most low-profile route and, for many SMEs, the most profitable one. It does not require submitting a project to any call for applications: the company identifies the qualifying expenditure for the financial year (research staff, depreciation of dedicated equipment, materials consumed in the project, subcontracts with technology centres), documents it correctly, and deducts it in the Corporate Income Tax return. If the gross tax liability is not sufficient to absorb the full deduction, the balance can be applied over the following 18 financial years or, in certain cases, claimed as a cash payment.
The risk lies in a tax authority audit. To neutralise it, there is the Binding Motivated Report (IMV): a report issued by the Ministry of Science and Innovation (through bodies such as the State Research Agency or the CDTI) that is binding on the tax authority regarding the classification of expenditure. Obtaining it before making the deduction makes the company's tax position virtually unassailable.
CDTI: business R&D projects
The Centre for the Development of Industrial Technology (CDTI), under the Ministry of Science, directly finances business projects through three main instruments:
- R&D Projects: partially reimbursable loans (non-reimbursable tranche of 33% for SMEs) with financing of up to 85% of eligible expenditure. Indicative minimum budget: €175,000.
- Direct Innovation Line (LIC): loans for technological innovation projects. Minimum eligible budget: €175,000. Suitable for industrial SMEs with more substantial process-improvement projects.
- Neotec: for recently created technology-based companies. Relevant if the company is in its early years.
For an industrial SME without an R&D team, the LIC is the standard entry point: projects with a minimum eligible budget of €175,000, with financing coverage of up to 75% of the approved budget (up to 85% when co-financed with FEDER funds).
Regional calls: Castilla y León and beyond
Regional governments publish annual grant calls for business innovation that, in many cases, are complementary to CDTI funding and tax deductions. In Castilla y León, the regional government runs programmes to support business innovation channelled through ADE (the Castilla y León Agency for Innovation, Financing and Business Internationalisation). The grants include:
- Direct subsidies for R&D expenditure (staff, materials, contracting of technology centres).
- Support for obtaining the Innovative SME seal from the Ministry of Science.
- Social security contribution rebates for research staff (Article 35.2 of the Corporate Income Tax Act in conjunction with Science Act 14/2011).
The Innovative SME seal is particularly valuable: it allows companies to compete for public tenders with an advantage on innovation criteria, facilitates access to European instruments, and formally accredits innovation activity to third parties.
Horizon Europe: more accessible than it appears
The European Union's framework programme for R&D 2021–2027 has a total budget of €95.5 billion. Many industrial SMEs rule it out, considering it the exclusive domain of universities and large corporations. However, the EIC Accelerator (European Innovation Council) is specifically designed for innovative SMEs and start-ups, with grants of up to €2.5 million and the possibility of additional equity investment.
The most realistic route for an industrial SME with no European experience is collaborative projects in consortia led by a technology centre or university: the company provides the real-world use case, the technology centre leads the proposal and coordination, and the SME gains access to European funding with a manageable level of bureaucracy. Networks of Technology Institutes (REDIT in the Valencian Community, TECNALIA in the Basque Country, ITCyL in Castilla y León) are the usual entry point.
Why industrial SMEs fail when applying for these grants
At Summum Consultora we have spent more than a decade supporting industrial SMEs in accessing R&D grants and have identified three recurring causes of rejection or under-utilisation:
- Failing to document while the work is being done. The project is executed, but nobody records the hours spent, the technical problems encountered, the failed experiments or the design decisions taken. When an audit or justification is required, there is no evidence that the activity ever took place.
- Confusing productive activity with R&D activity. Manufacturing a special order is not R&D. But developing the process to manufacture it — with genuine technical uncertainty, iterations and tests — can be. The line is drawn by documentation and intent, not the final result.
- Presenting the technical report as though it were a sales brochure. The authorities want to read about technical uncertainties, the state of the art, expected advances and methodology. A report that sounds like a marketing leaflet does not qualify.
The role of specialist R&D consultancy
A company without an R&D department can access these grants perfectly well, provided it has the right support. The work of a specialist consultancy covers what the company cannot do internally:
- Eligibility audit: review of ongoing projects to identify which activities qualify as R, D or TI under the current legal criteria.
- Technical report writing: translating shop-floor or production language into the language required by the authorities (state of the art, hypotheses, methodology, expected results).
- Binding Motivated Report application: processing the application to the CDTI or AEI to safeguard the tax deduction.
- Justification and monitoring: preparation of expenditure documentation, time sheets and progress reports required by the calls.
- Coordination with the tax adviser: integration of the deduction into the corporate tax return with the correct safeguards.
What the consultancy cannot replace is the technical content: the company must know its own process, its real problems and its solutions. The consultancy provides the methodology and language; the company provides the sector's technical knowledge. It is a collaboration, not a total outsourcing.
If you want to find out whether your current projects qualify for any of these routes, our R&D consultancy team carries out an initial, no-obligation assessment for industrial companies in Castilla y León and the Canary Islands.
How much money can actually be recovered: indicative examples
Without citing consultancy fees or guaranteeing specific results, it is possible to illustrate the order of magnitude using public data:
| Scenario | Estimated eligible expenditure | Route used | Indicative tax benefit / grant |
|---|---|---|---|
| SME of 20 employees improving a laser-cutting process (TI) | €80,000/year | Deduction Art. 35 CIT Act (12%) | ~€9,600 off corporate tax liability |
| SME of 40 employees developing proprietary tooling (D) | €150,000/year | Deduction Art. 35 CIT Act (25%) + IMV | ~€37,500 off corporate tax liability |
| SME of 35 employees with a line-automation project | €200,000 project | CDTI Direct Innovation Line | Up to €150,000 (75%) in a partially subsidised loan |
| SME in a European consortium (collaborative H2020/HE project) | €300,000 SME budget | Horizon Europe (70% grant) | ~€210,000 in direct grant funding |
These figures are indicative only and depend on the company's profile, the technical quality of the project, and compliance with each call's requirements. Nevertheless, they illustrate that the potential return more than justifies the effort of documentation and administration.
Concrete steps to get started this week
- List the technical projects under way or completed in the past 4 years. Include process improvements, tooling development, automation projects and any activity in which there was real technical uncertainty.
- Retrieve available records: technical emails, drawings, test reports, time sheets, non-conformance records. These are the raw material for documentation.
- Identify the expenditure: hours of technical staff involved, materials consumed, subcontracts, depreciation of specific equipment.
- Consult a specialist to assess what proportion of that expenditure is eligible and which route is most appropriate (tax deduction, CDTI, regional or European).
- Implement a minimum tracking system for future projects: a weekly timesheet by project, a technical incident log, and an evidence folder per activity. With that, the bulk of the documentation work is resolved.
Frequently asked questions
Can an industrial SME without engineers on the payroll access the R&D tax deduction?
Yes. The regulation does not require engineers with a specific qualification or a formal department. It requires that the activity is technically classifiable as R, D or TI and that the expenditure is correctly documented. The staff can be qualified operatives, process technicians or external personnel. What matters is that there is real, traceable dedication to technological innovation activities.
Can the corporate tax deduction be combined with a CDTI grant?
Yes, with caveats. The tax deduction base must be reduced by the amount of any non-reimbursable grant received (the "outright grant" portion). The reimbursable portion of the CDTI loan does not reduce the deductible base. In practice, the combination remains financially very advantageous and is the standard strategy for larger projects.
How far back can an R&D tax deduction be claimed?
The deduction is generated in the financial year in which the expenditure is incurred and can be applied over the following 18 tax years if the tax liability is insufficient to absorb it. However, verification of expenditure and classification of activities is subject to the general tax limitation period (4 years). Obtaining the IMV before taking the deduction provides protection against subsequent audits.
What is the difference between a CDTI grant and an R&D tax deduction?
The CDTI grant (or partially reimbursable loan) is money that enters the company's cash flow directly: the CDTI finances a percentage of eligible expenditure before or during project execution. The tax deduction, on the other hand, reduces the corporate tax bill after the project has been executed: no cash comes in, but less tax is paid. Both are compatible and complementary. For projects with a large budget, the most common combination is to finance execution with a CDTI loan and deduct the remaining eligible expenditure in the corporate tax return.
