The Zentrales Innovationsprogramm Mittelstand (ZIM) is open to all technologies and sectors, but it isn't open to everyone. Anyone applying has to meet five core conditions at the same time. If one is missing, the project is rejected or clawed back later[1].
SME status and company size
ZIM is aimed at mid-sized companies. The limit is up to 1,000 employees, which goes beyond the EU SME definition of 249[4]. For single projects the narrower SME definition applies: up to 499 employees, €50m turnover and a €43m balance sheet total. Cooperation projects open the programme to companies with up to 1,000 employees as well.
The decisive pitfall: linked companies are aggregated. Anyone who ignores a parent company, a sister company or a holding of more than 25% may lose SME status retroactively, with clawback as the consequence[1]. SME status therefore has to be documented across all linked companies before the application is filed.
A research and development project
The project has to be a demanding R&D project with recognisable technical risk. The reviewer checks whether it goes beyond the known state of the art. Typical grounds for rejection: the project describes a market adaptation rather than a new development, the technical risk isn't named, or it is pure system integration with off-the-shelf components[1].
The state aid category matters: Article 25 GBER distinguishes between industrial research and experimental development. The category determines the maximum funding rate[3]. ZIM applications should name the R&D category explicitly rather than leaving it to the reviewer.
Your own R&D share
ZIM doesn't fund pure contract research. The company has to make its own R&D contribution: its own staff, its own knowledge gain, its own technical risk. Anyone who contracts the entire project out to third parties does not meet this condition[1].
External services are eligible up to 35% of direct staff costs. That limit relates exclusively to direct staff costs, not to the total project budget. Every external service also has to make an independent, documented research contribution; routine services or contract manufacturing don't qualify[2].
Financial capacity
The company has to be able to fund its own share of the project costs from its own resources. The project management agency assesses financial capacity during the application procedure. Companies in insolvency or with negative equity are not eligible. Companies in difficulty within the meaning of the EU guidelines are also outside the scope[1].
In practice that means: before applying, make sure the company's own share — typically 55 to 75% of eligible project costs depending on the funding rate — can be covered from current cash flow or existing credit lines, so the project doesn't founder on financing.
No early project start
No ZIM criterion leads to rejection more often than this one: any project-related activity before the application arrives at the agency disqualifies the project. That covers staff assignments, orders and contracts with partners, and on a strict reading also concept or feasibility studies that feed directly into the ZIM project[1].
The decisive date is when the application arrives at the agency, not the date of the funding decision. So the project may only start after submission, with the decision typically following 3 to 5 months later[4]. That gap has to be built into the project plan.
Market relevance
ZIM is not a basic research programme. The project has to have clearly recognisable market potential: who are the users, what is their willingness to pay, how does the path run from development to exploitation? Purely academic projects with no recognisable route to market are rejected[1].
The application has to answer those points concretely, not as marketing copy but as a plausible argument to the reviewer. An exploitation plan with target market, addressable volume and a realistic go-to-market path belongs in every full application.
Further checks: double funding and cooperation
Double funding: ZIM can be combined with the Forschungszulage under the FZulG, but not on the same staff hours. The ban on cumulation in Article 8 GBER and § 7 FZulG prohibits funding the same expenditure twice. Anyone using both programmes needs a clean cost separation at the level of time recording[3].
Cooperation projects: in cooperation projects all partner applications have to reach the agency within 14 days for them to count as belonging together. If one partner delays submission, the decisive date shifts for the whole project[2]. In addition, since 1 January 2025 AiF Projekt GmbH is responsible exclusively for cooperation projects while single projects go to VDI/VDE-IT, so the right agency has to be addressed from the start.
Funding for cooperation projects is 5 percentage points higher than for single projects. Anyone who can choose between the two formats should factor that difference into their calculations. The article on ZIM funding rates gives a detailed overview of the 2026 rates.
FAQ
How large can a company be to apply for ZIM? Mid-sized companies with up to 1,000 employees can apply. For single projects the narrower SME limit applies: up to 499 employees, €50m turnover and a €43m balance sheet total. Linked companies are aggregated[4].
What does "no early project start" mean? Any project-related activity — staff assignment, order, contract — before the application arrives at the agency disqualifies the project. Concept work that feeds directly into the ZIM project can also count as a start on a strict reading[1].
Does a ZIM project have to carry technological risk? Yes. ZIM funds only projects that go beyond the known state of the art and carry recognisable technical risk. Routine development and pure market adaptations don't qualify[1].
Can I combine ZIM with the Forschungszulage? Yes, as long as the same person-hour isn't claimed under both programmes. The ban on cumulation in the GBER and the FZulG requires a clean cost separation at the level of time recording[3].
Do shareholdings count for the SME test? Yes. Parent companies, sister companies and holdings above 25% are added together for the SME test. Ignoring that risks losing status retroactively and facing clawback[1].

ZIM: which costs are eligible
