ZIM is the federal government's largest technology- and sector-open R&D funding programme for mid-sized companies. Applications run all year and entirely digitally: there are no fixed deadlines. What there is, is a clearly structured process you need to know before you write the first sentence of the application.
Step 1: check eligibility
Before you submit anything, check three basic conditions.
- SME status: companies with up to 1,000 employees and a registered office or operating site in Germany can apply. Important: linked companies — parents, sisters or subsidiaries with holdings above 25% — are aggregated for the headcount. Ignoring that risks clawback.
- The project's R&D character: the project needs demanding technical risk and a clearly recognisable market objective. Pure routine development, contract manufacturing or market adaptation of existing products are not eligible.
- Your own R&D share: you have to deploy your own R&D staff. Simply contracting the development work out to third parties, with no involvement of your own, will not be approved. External services are only eligible up to 35% of direct staff costs.
If you are unsure whether the project is suitable for ZIM, you can submit a project outline to the responsible agency for a pre-check. That pre-check is optional but gives clarity early and saves time where the project has fundamental defects.
Step 2: choose the right project management agency
Since 1 January 2025 there have been two responsible agencies, depending on the project type:
- VDI/VDE Innovation + Technik GmbH (ZIM-Foyer): responsible for single projects, feasibility studies and innovation networks.
- AiF Projekt GmbH (ZIM-KOOP): responsible for cooperation projects between at least two companies or between a company and a research institution.
The choice of project type has a direct effect on the funding rate. For cooperation projects the rate is 5 percentage points higher than for a single project. If you are planning a single project and a cooperation project in parallel, from 2025 you have two agencies to deal with, with separate portals but a common application standard.
Step 3: prepare the application
The ZIM application is a full application, not a statement of intent. You have to work out the following components completely before you start submitting:
- Project description: the technical starting position, R&D objectives, work plan, milestones and a clear boundary between routine work and R&D.
- Cost and financing plan: broken down into staff costs, external services (max. 35% of direct staff costs), project-related material and travel costs, and depreciation. For SMEs with fewer than 50 employees, an overhead flat rate of 120% of staff costs has applied since the reform, replacing the earlier itemised evidence.
- Exploitation plan: market potential, the target group's willingness to pay and a concrete go-to-market path. Without plausible market relevance the application is rejected.
- Proof of creditworthiness: you have to evidence the financial capacity to fund your own share.
For cooperation projects there is an additional rule: all cooperation partners have to submit their applications to the agency within 14 days. If one partner is late, the arrival date shifts for the whole project, with consequences for the decision date.
Step 4: submit the application
Submission is exclusively digital through the Förderzentrale Deutschland (FZD). No post, no email. The time the application arrives at the agency is legally decisive: it determines which version of the guideline applies, which approval round the project falls into and, crucially, what counts as an early project start.
Starting the project before the application arrives is prohibited. Every project-related staff assignment, every contract with a supplier and every investment made before the application reaches the agency counts as an early start and leads to rejection. That also applies to preliminary studies or concept work where they are substantively attributable to the project applied for.
Step 5: wait for the assessment
Once it arrives, the agency assesses the application technically with external reviewers. The criteria are degree of innovation, technical risk, market potential and feasibility. From arrival to funding decision typically takes 3 to 5 months.
Approvals are subject to available budget. For 2026 the ZIM budget is set at €558m in the federal budget, which significantly reduces the risk of an approval freeze compared with periods of provisional budget management, though it doesn't rule it out entirely.
If you receive a positive decision, your project only begins once the funding decision has been served. No decision, no start.
Step 6: after the decision
The funding decision starts the delivery phase. Typical project terms run 18 to 36 months. During that time the following obligations apply:
- Interim reports every 12 months, on substance and on costs.
- A statement of use at the end of the project, with complete cost documentation.
- A retention obligation for all project-related records: 10 years.
- Project changes — moving the end date or swapping cooperation partners, for instance — have to be requested from the agency in advance. Unilateral changes endanger the funding.
If you combine ZIM with the Forschungszulage, watch the ban on cumulation: the same person-hour may not be claimed both in the ZIM statement of use and in the FZulG application. A clean cost separation at the level of individual hours is mandatory.
Common mistakes in a ZIM application
- Starting the project early: the most common ground for rejection. Even preparatory studies or contract awards before the application arrives can count as a start.
- No market relevance: purely academic projects with no recognisable exploitation objective are rejected. The application has to set out users, willingness to pay and a marketing strategy plausibly.
- SME status not properly checked: holdings above 25% in linked companies raise the aggregated headcount. Overlooking that risks clawback after approval.
- Missing the 14-day cooperation deadline: if one cooperation partner submits late, the whole project counts as submitted late.
- Double funding with the Forschungszulage: claiming identical staff hours in both programmes is not permitted and can lead to clawback.
Structuring the application around the agencies' assessment criteria — degree of innovation, technical risk, market potential, feasibility — measurably raises the chance of approval.
FAQ
When can I file a ZIM application?
ZIM has no fixed deadlines. You can submit an application all year round. Applications are processed in the order they arrive.
Where do I submit the ZIM application?
Exclusively digitally through the Förderzentrale Deutschland (FZD). For single projects the agency is VDI/VDE-IT (the ZIM-Foyer portal), for cooperation projects AiF Projekt GmbH (the ZIM-KOOP portal).
How long does a ZIM application take to process?
From arrival to funding decision typically takes 3 to 5 months. A project outline submitted for a pre-check is answered faster.
May I start the project before the decision?
No. Every project-related staff assignment, contract or purchase before the application reaches the agency counts as an early project start and leads to rejection. The project may only start after the funding decision.
What do I have to submit after approval?
Interim reports every 12 months and a statement of use at the end of the project. Records have to be kept for 10 years.
