On 21 May 2025, the European Commission presented a new package of simplification measures that will slash a further €400 million per year in administrative costs for businesses across the EU, building on the €8 billion already targeted through previous efforts. This is the fourth Simplification Omnibus presented under the current mandate, following previous efforts to streamline sustainability reporting, agricultural policy, and investment regulations. Central to this proposal is the creation of a new company category — small mid-caps (SMCs) — defined as enterprises with fewer than 750 employees and either up to €150 million in turnover or up to €129 million in total assets. Nearly 38,000 such companies across the EU will now benefit from existing SME exemptions and simplified rules, including under the GDPR and EU listing requirements. Further measures include exempting around 10,000 low-volume businesses from mandatory registration in the F-gas Portal, simplifying GDPR record-keeping by focusing only on high-risk processing activities for organisations with fewer than 750 employees, and replacing paper-based product compliance documentation with digital processes. The Commission is also extending the compliance deadline for due diligence rules in the battery sector to 2027, offering businesses more time to adapt and establish verification frameworks. The next packages will address the defence, chemical, and digital sectors, continuing the Commission’s commitment to reduce red tape and foster a regulatory environment that promotes innovation and growth.
