SME Definition in Horizon Europe
The definition of a Small and Medium-sized Enterprise (SME) in Horizon Europe is provided by the Directorate-General for Internal Market, Industry, Entrepreneurship and SMEs. This definition also applies to Horizon 2020.
According to the EU Recommendation 2003/361, an enterprise qualifies as an SME if it meets the following criteria:
- Fewer than 250 employees, and
- Either:
- Annual turnover not exceeding €50 million, or
- Balance sheet total not exceeding €43 million
SMEs make up 99% of all businesses in the EU, and the SME definition plays a key role in determining eligibility for EU funding and support programmes specifically designed for smaller enterprises.

Key Criteria for SME Classification
Two main factors determine SME status:
- Staff Headcount
- Financial Thresholds:
- Annual turnover, or
- Balance sheet total
⚠️ Important: If a company is part of a larger corporate group, it may need to include the relevant data from the entire group (e.g., headcount, turnover, balance sheet) when assessing SME status.
