SME Definition: How to Calculate EU SME Status and the Funding Rate It Sets

The EU SME definition is the test, set out in Commission Recommendation 2003/361/EC, that decides whether a company counts as a micro, small or medium-sized enterprise. Under that Recommendation, a company qualifies with fewer than 250 staff and either turnover of up to €50 million or a balance sheet of up to €43 million. The count includes the companies that own it and those it owns.

Most founders know the headline thresholds. Fewer know how funders count staff, whose figures get added to yours, or when status changes. This guide applies the SME definition the way a funding authority does, then shows what the result is worth in 2026.

What is the EU SME definition?

Under the EU SME definition, a company is small or medium-sized if it has fewer than 250 staff. It also needs annual turnover of up to €50 million or a balance sheet total of up to €43 million. The staff ceiling always applies. Of the two financial ceilings, a company only has to stay under one.

On their own, the ceilings look at a single company. The European Commission adds that a firm that is part of a larger group may need to include the group's staff and financial data as well. Most status errors start with that sentence.

The Commission's 2020 user guide to the definition opens with a line from Jean-Claude Juncker, then President of the European Commission, who called SMEs "the backbone of our economy" (PDF).

In Germany, the word Mittelstand is often used as if it meant SME. Our article on how the Mittelstand differs from SMEs sets out the German definitions. For funding, only the EU test decides the rate.

How do you count staff for the SME definition?

The SME definition counts staff in annual work units (AWU) rather than heads. According to the Commission's 2020 user guide, one person working full time for the whole reference year equals one AWU. Part-time and seasonal staff count as the fraction of the year they worked. The figures come from the last approved annual accounts.

Article 5 of Commission Recommendation 2003/361/EC sets out who belongs in the count:

• employees
• people working for the company who are treated as employees under national law
• owner-managers
• partners who work in the business regularly and draw financial benefits from it

Two groups stay out. Apprentices and students with an apprenticeship or vocational training contract are not counted in the SME headcount, and neither is time spent on maternity or parental leave. For a company close to 250, check those exclusions first.

Turnover is taken net of VAT and other indirect taxes. A newly founded company with no closed accounts uses a good-faith estimate for the current financial year instead. Keep the business plan behind it, in case a funder checks.

Which partner and linked company figures do you add?

Under Commission Recommendation 2003/361/EC, you add the figures of every company that holds 25% or more of yours, and of every company in which you hold 25% or more. Partner companies, with stakes from 25% up to 50%, count in proportion to the stake. Linked companies, where the stake is over 50% or one company controls the other, count in full.

Source: Commission Recommendation 2003/361/EC, Annex, Articles 3 and 6.

The Commission's 2020 user guide works the sum through for a company with partner stakes of 25%, 33% and 49%. The total is 100% of the company's own figures plus 25%, 33% and 49% of each partner's figures. The figures of a partner's own partner are not added.

Under Article 3 of the Recommendation, some investors can hold up to 50% without creating a partner link, provided they are not linked to you:

• public investment corporations and venture capital companies
• business angels whose total investment in your company is less than €1,250,000
• universities and non-profit research centres
• institutional investors, including regional development funds
• autonomous local authorities with an annual budget under €10 million and fewer than 5,000 inhabitants

Public ownership works the other way. Under the same article, if public bodies control 25% or more of the capital or voting rights, directly or indirectly, the company is not an SME at all.

Formal shareholdings are only part of the test. In HaTeFo, decided on 27 February 2014, the Court of Justice of the European Union (CJEU) answered a question from Germany's Federal Fiscal Court (Bundesfinanzhof). A tax office had refused HaTeFo the higher SME rate under the 2005 investment-allowance law. Companies forming a single economic unit through the same natural persons count as linked, the Court held, even without any formal link.

The step most applicants skip is looking upwards. Test the holding company above the applicant, and everything else that holding company owns.

When do you gain or lose SME status?

A company gains or loses SME status only after crossing a ceiling in two consecutive accounting periods, under Article 4 of Recommendation 2003/361/EC. One strong year changes nothing. The buffer does not cover a change of ownership: after a merger or acquisition, the Commission's user guide says the loss of status may be immediate.

For the Forschungszulage, the test runs year by year. According to the Saxony-Anhalt finance ministry's May 2026 guidance, the SME thresholds relate to the financial year for which the allowance is claimed, with the same two-year rule on top.

The risk of losing SME status is highest during a running grant. The European Innovation Council (EIC) assesses a loss of SME status during an EIC Accelerator project case by case. It states that an ownership change can end the grant, with costs ineligible from the date the transaction completes.

A European Ombudsman case published in February 2024 shows how a mid-project loss of status plays out. In case 533/2022/PB, the European Innovation Council and SMEs Executive Agency (EISMEA) ended a grant after the beneficiary was acquired and lost its SME status. The Ombudsman found the termination justified but the delays maladministration, and EISMEA now informs beneficiaries within 15 working days when termination is likely.

Before you sign a term sheet or a share purchase agreement:

1. Re-run the SME test on the cap table as it will look after the deal.
2. List every running grant or claim that depends on SME status.
3. Read each funder's rules on ownership changes, and tell the funder early if status will change.

SME status also shapes the firms-in-difficulty test, where young SMEs get an exemption that large companies do not. Our guide to the research allowance and firms in difficulty explains the young-SME exemption in detail.

Why does SME status set your funding rate?

SME status sets your funding rate because EU state-aid rules allow higher aid for smaller companies, and German and EU programmes build that into their own conditions. Under the Forschungszulagengesetz (FZulG), SME status lifts the Forschungszulage, Germany's R&D tax allowance, from 25% to 35% on eligible costs incurred after 27 March 2024 (PDF, in German).

The Forschungszulage is the clearest case of SME funding in Germany. From 2026 the assessment basis is capped at €12 million a year. According to the German Chamber of Industry and Commerce (DIHK), the allowance therefore tops out at €3 million at 25% and €4.2 million at 35%.

For linked companies, Section 3(6) of the FZulG applies one cap to the whole group. Our complete Forschungszulage guide lists the rates and caps for every year.

The General Block Exemption Regulation (GBER), known in German as the Allgemeine Gruppenfreistellungsverordnung (AGVO), sets ceilings rather than rates. Its R&D ceilings run from 70% for small companies in industrial research down to 25% for large companies in experimental development. That range comes from the Research Council of Norway's 2026 summary of Article 25.

Under GBER Article 25, bonuses for collaboration can lift aid to a maximum of 80% of eligible costs. Each German grant programme then sets its own rate at or below those ceilings.

Eurostars shows the hard edge of the SME line. Germany's research ministry, the Bundesministerium für Forschung, Technologie und Raumfahrt (BMFTR), funds SMEs in a Eurostars project at up to 50% of eligible costs. Under the September 2026 call, German funding is capped at €500,000 for all German partners per project. Large companies receive no German funding and must file a self-funding declaration.

At EU level, the European Innovation Council (EIC) Accelerator grant of below €2.5 million is reserved for start-ups and SMEs.

Horizon Europe is size-neutral. Under its 2026 to 2027 work programme, innovation actions pay for-profit companies 70% of eligible costs (PDF), whatever their size. Our guide to Horizon Europe grants explains what a company receives and when.

Two of our Forschungszulage cases show the 10-point gap in euros. A growing SaaS company with two certified database projects received €1.4 million on an eligible base of about €4 million. That matches the 35% SME rate, as our case study on research allowance for software projects shows. At the 25% standard rate, the same base would have produced €1 million (illustrative: 25% × €4 million).

An energy and blockchain company with two certified projects received €1.9 million on an eligible base of €7.6 million. That is the standard 25% rate, as our case on the research allowance amount for energy projects sets out. The case page also notes that affiliated companies share one cap.

How do you prove SME status to a funder?

You prove SME status with a signed self-declaration on each funder's own form, backed by your accounts and ownership records. The European Commission's user guide contains a model declaration, and German funders such as KfW and the tax authorities use their own versions.

• EU Funding & Tenders Portal: when an EU call depends on SME status, the portal asks for an SME self-assessment, which you must repeat if none was done in the last two years. Without it, you can be blocked from submitting.
• Research Executive Agency (REA): the agency's validation service runs ex-post checks on SME and mid-cap status (PDF).
• Forschungszulage: Saxony-Anhalt's finance ministry publishes a signed self-declaration on the SME definition (Anlage 3) for claimants.
• KfW: the federal development bank asks for its own self-declaration and examines the last three completed financial years (PDF, in German).

Every SME declaration rests on the same evidence:

• the last approved annual accounts for your company and for every partner and linked company
• an annual work unit (AWU) calculation for the reference year
• a cap table showing every holder of 25% or more, upwards and downwards
• for a company without closed accounts, the business plan behind your estimate

The Forschungszulage rate follows from SME status, so BeFunded checks status before anything is filed. We work through your annual work units, last approved accounts and cap table, including every partner and linked company. We then confirm whether the 35% rate holds for the year you claim.

Our research allowance consulting runs the claim from the Bescheinigungsstelle Forschungszulage (BSFZ), which certifies the R&D, to the tax office. The fee is 10% of the allowance up to €500,000 a year and 5% above, due only after payout.

What happens when you outgrow the SME definition?

Passing the SME ceilings now leads into a new EU category, although the higher SME rates stay behind. Commission Recommendation (EU) 2025/1099 of 21 May 2025 defines a small mid-cap as a company that is not an SME and has fewer than 750 staff. Its turnover must stay at or below €150 million, or its balance sheet at or below €129 million.

In its 2025 factsheet, the Commission puts the number of small mid-caps in the EU at about 38,000 (PDF). The Recommendation leaves the SME thresholds unchanged, so the 35% Forschungszulage rate still stops at the SME line. Our funding for large companies service covers what stays open above it. One EU route remains: the European Innovation Council (EIC) Accelerator admits small mid-caps with up to 499 employees for its equity component.

The aid ceilings may also move. According to the Commission's 2024 training material, the current General Block Exemption Regulation (GBER) applies until 31 December 2026 (PDF). The European Commission plans a revised GBER, with entry into force on 1 January 2027. Recheck your rates once it is published.
