Small and Medium-Sized Enterprise (SME) Definition (EU)

Whether a business qualifies as an SME under EU law is not merely a label: it determines eligibility for reserved contracts, the proportionality of financial thresholds a buyer may impose, and access to a wide range of public support programmes. The definition originates in Commission Recommendation 2003/361/EC, which remains the authoritative reference for public procurement purposes across European member states and EEA countries including Norway and Liechtenstein.

What is the Small and Medium-Sized Enterprise (SME) Definition (EU)?

The EU SME definition uses three quantitative thresholds applied at the level of the individual enterprise, adjusted for linkages with other enterprises.

Micro enterprise. Fewer than 10 employees and either annual turnover or annual balance-sheet total not exceeding EUR 2 million.

Small enterprise. Fewer than 50 employees and either annual turnover or annual balance-sheet total not exceeding EUR 10 million.

Medium-sized enterprise. Fewer than 250 employees and either annual turnover not exceeding EUR 50 million or annual balance-sheet total not exceeding EUR 43 million.

The thresholds are applied to two consecutive accounting periods. An enterprise that exceeds a threshold in one year does not lose its SME status until it has exceeded the threshold in two successive years, providing stability during periods of growth.

Critically, the definition includes an independence test. A business that is owned 25 percent or more by a single enterprise that is not itself an SME is classified as a "partner enterprise," and the partner's figures must be added in proportion to the ownership share. Ownership above 50 percent makes the other enterprise a "linked enterprise," whose full figures are consolidated. This prevents large corporate groups from qualifying for SME status through subsidiary structures.

In the UK, the Procurement Act 2023 and associated guidance reference the same headline thresholds for policy purposes, though the legal basis is domestic rather than the EU Recommendation after the UK's exit from the EU.

Why it matters for bidders

The classification affects how buyers are permitted to treat your business during a procurement. Under SME-friendly procurement policies, buyers must keep financial capacity thresholds proportionate, and for reserved contracts under Article 20 of Directive 2014/24/EU, eligibility is limited to sheltered workshops and certain social enterprises. Knowing your classification also helps when responding to selection questionnaire questions that ask suppliers to self-declare their size category, which buyers use for statistical reporting to the European Commission.

If you are part of a corporate group, calculating your true classification requires aggregating figures with linked and partner enterprises. Getting this wrong can constitute a material misrepresentation in a tender.

Example

A software development company with 60 employees and EUR 12 million turnover appears at first glance to be a medium-sized enterprise. However, a private equity firm owns 60 percent of its shares, and the private equity firm is not itself an SME. Because the ownership exceeds 50 percent, the private equity firm's figures are consolidated: the combined headcount and turnover far exceed the medium-enterprise thresholds. The software company is therefore not an SME for EU procurement purposes, even though it looks small in isolation.

Frequently Asked Questions

Do the EU SME thresholds apply in the UK after Brexit?

The UK uses the same headline employee and turnover thresholds for policy purposes, and the Procurement Act 2023 requires contracting authorities to consider barriers facing SMEs. However, the legal basis is UK domestic policy rather than Commission Recommendation 2003/361/EC. The independence test works similarly but is applied under UK guidance rather than EU law.

Can a company self-certify its SME status in a tender?

Yes. The European Single Procurement Document (ESPD) allows suppliers to self-declare their SME classification without providing certificates at the tender stage. Buyers may verify the classification before contract award. False self-declaration can result in exclusion and, in serious cases, debarment.

Do the thresholds change over time?

The thresholds in Commission Recommendation 2003/361/EC have remained unchanged since 2005, though the European Commission has periodically reviewed them. Businesses operating in Norway, Iceland, and Liechtenstein under the EEA Agreement apply the same thresholds through incorporation of the Recommendation into EEA law.
