ZIM vs. Research Allowance Germany: Comparison 2026

For CFOs, CTOs and R&D leads, the ZIM vs. Research Allowance Germany comparison is no academic question. It shows up in liquidity, in the effective tax rate and in the financeability of an entire development portfolio. Both instruments fund research and development, yet they differ considerably in who gets in, when the money arrives, what evidence they demand and how far they scale.

ZIM vs. Research Allowance: Two Funding Programmes at a Glance

What is the Central Innovation Programme for SMEs (ZIM)?

The Central Innovation Programme for SMEs (ZIM) is a funding programme of the Federal Ministry for Economic Affairs and Energy (BMWE) that has backed technology-oriented SMEs with direct grants since 2008. It funds market-oriented innovation projects, feasibility studies and network initiatives, and it stays open to every sector. Working with pre-defined project budgets, it is built for projects with a sharp boundary, a traceable start, a defined end and a commercialisation path. One caveat now overrides all of that: since midday on 7 July 2026, ZIM has been accepting no new applications at all, project outlines included. Applications already submitted are still being decided and payments run on as agreed, and the one route still open runs through the bilateral and multilateral international calls.

More than 60,000 funded projects have accumulated since the programme started, a figure quoted in chamber of commerce guidance on ZIM; the programme's own ZIM statistics carry the running count. A number of that order is evidence of how broadly the programme is accepted across the German SME sector.

What is the tax-based Research Allowance?

The Research Allowance is a tax-based instrument resting on the Research Allowance Act (FZulG), in force since January 2020. It is non-dilutive, needs no equity stake and never has to be repaid. In practice it runs in two stages: the BSFZ, the certification body for the Research Allowance, certifies that the work is R&D at all, and the tax office then assesses the amount. Two later laws improved the terms considerably, the Growth Opportunities Act (March 2024) and the Act for a Tax-Based Immediate Investment Programme (July 2025).

Funding Requirements and Target Groups Compared

The decisive question is not whether a project looks innovative, but whether it fits the logic of the programme in question. ZIM judges projects heavily ex ante. The Research Allowance asks instead whether the R&D criteria are met and which eligible expenses actually arose in the financial year.

Who can apply for ZIM?

ZIM funding for SMEs targets small and medium-sized companies under the EU definition, plus other mid-sized firms with fewer than 500 employees, affiliated and partner companies included; the old revenue threshold disappeared with the 2025 directive, which also opened the programme to firms of fewer than 1,000 employees where they cooperate with a funded SME. What carries an application is technical risk, degree of novelty, a credible commercialisation case and robust project planning. Topics and sectors stay open: a mechanical engineering firm with a new manufacturing process stands on the same footing as a software company building an AI module. All of that describes the programme in normal operation, and normal operation is exactly what is suspended: since 7 July 2026 no new applications are being taken.

Who benefits from the Research Allowance?

Tax-based research funding in Germany is open in principle to every company, whatever its legal form. SMEs under the EU definition have had an increased rate of 35 per cent since March 2024, while large companies stay at the standard 25 per cent. Where R&D runs continuously, in software, biotech, mobility or engineering, that model scales considerably better than a one-off project grant.

Which Sectors and Topics Both Programmes Cover

Both programmes are open to all sectors. New algorithms, sensor technology, manufacturing processes, drug development platforms, energy systems and climate-relevant processes all qualify. By contrast, the following do not:

• Routine development and pure product maintenance
• Standard integration or mere scaling of existing software
• Mandatory regulatory work that carries no technical uncertainty of its own
• Bug fixing and UI work with no experimental element

Funding Amounts and Funding Rates: Which Delivers More?

In an R&D funding comparison, the nominal amount is only one of four things that matter. The others are the assessment basis of the Research Allowance, how predictable the payout is and how much internal work the application swallows before any money moves.

How much funding does ZIM provide?

ZIM funding depends on the project type and the partner setup. Three of the four figures below cap the eligible costs, and only network management caps the grant itself:

• Individual projects: 25 to 45 per cent of eligible costs, and those costs are capped at EUR 690,000
• Feasibility studies: eligible costs of up to EUR 125,000 per company, funded at 50 to 70 per cent
• Cooperation projects: 30 to 55 per cent nationally, 40 to 60 per cent with foreign partners, on eligible costs of up to EUR 560,000 per company
• Network management: a grant of up to EUR 490,000 for national networks, up to EUR 600,000 for international ones

How much is the Research Allowance in Germany?

Since January 2026, after the changes brought by the Growth Opportunities Act and the Immediate Investment Programme, the assessment basis runs to EUR 12 million per financial year. For SMEs that means a maximum Research Allowance of EUR 4.2 million at 35 per cent; for large companies the ceiling is EUR 3 million at 25 per cent.

For projects starting after 31 December 2025, a flat rate of 20 per cent of the other eligible expenses covers the overheads and operating costs of in-house research on top of the wages themselves. Take a ten-person AI startup with EUR 420,000 in eligible wage costs: the wages alone yield roughly EUR 147,000 in allowance, before that flat rate is added.

Worked Example: ZIM vs. Research Allowance at Different Personnel Costs

Assume a ZIM grant of EUR 120,000 for one self-contained development project. At the 35 per cent SME rate, the Research Allowance draws level at around EUR 345,000 in eligible personnel costs, and above that threshold it keeps scaling in proportion to what a company actually spends on R&D.

Around that crossing point, a pragmatic comparison of funding programmes in Germany sorts into three cases:

• Up to roughly EUR 345,000 in eligible personnel costs, ZIM can come out ahead in nominal terms
• Above that, the Research Allowance scales better, because it attaches to annual expenditure rather than to one budget
• With continuous R&D or several sub-projects at once, the tax-based logic usually proves more robust than a single grant

TRUMPF, the laser technology manufacturer from Ditzingen, shows the scale German R&D budgets can reach: according to its annual report for 2023/24, the company spent more than EUR 500 million on research and development. A budget of that size runs far past the assessment basis, so the allowance is capped long before the spending is.

Application Process, Effort and Tax Treatment

Beyond the funding rate, the process decides. ZIM requires fully prepared application documents on the desk before the project starts, which is one reason the current freeze on new applications bites so hard in planning. The Research Allowance runs in two stages and can hook into the R&D cost tracking a company already has.

Application and Administrative Effort Compared

With ZIM, the project description, work packages, cost plan and commercialisation strategy have to be in robust shape early. The Research Allowance instead sends you through the BSFZ, the certification body for the Research Allowance, and then on to the tax office. Three habits carry most of the weight there:

• Draw the boundary of each R&D project and document it against the BSFZ criteria.
• Record personnel time, roles and technical uncertainties on a monthly basis.
• After the financial year ends, apply for the allowance at the tax office with a cost calculation that can be traced line by line.

The mistakes repeat themselves: routine development declared as R&D, staff time documented only on a flat-rate basis, standard implementation never separated from experimental work.

Is ZIM funding tax-free?

No. The grant counts as taxable operating income, so the tax treatment of the ZIM grant belongs in the profitability calculation from the start. Project-related expenses stay deductible at the same time. What counts in the end is the after-tax effect within the overall financing model, not the gross grant.

Retroactive Application for the Research Allowance

One advantage tends to go unused: applying for the Research Allowance retroactively works for every financial year that is not yet time-barred, which in practice means up to four years back. Development spending that left the account long ago can still be turned into liquidity. For startups that spent their early years deep in R&D without ever building a funding structure, it is regularly the largest single item we find.

Hourly Rates and Eligible Costs

What hourly rate does the Research Allowance allow?

For the hours sole proprietors and co-entrepreneurs put in themselves, the eligible hourly rate rose from EUR 40 to EUR 70 with the Growth Opportunities Act (March 2024), and under the Immediate Investment Programme it has stood at EUR 100 since 2026. In corporations, the directly attributable wages of the employees assigned to the project count instead. The roles that typically qualify:

• Software developers and data scientists
• Laboratory staff and test engineers
• R&D project leads with a verifiable share of their hours

Recognition depends on a direct link to the project, hours recorded as the work happens and technical documentation of the uncertainty that made it research in the first place.

Contract Research: Differences Between ZIM and the Research Allowance

For contract research, the Research Allowance has become distinctly more attractive since the Growth Opportunities Act: 70 per cent of the external remuneration goes into the assessment basis, which for an SME works out at 24.5 per cent funding (35 per cent of 70 per cent). ZIM can be strong for cooperation work too, though it asks for a tightly defined project structure and partner roles fixed in advance.

BioNTech shows how large those cost blocks can get: its full-year results report more than EUR 1.7 billion of R&D spending in 2023. What the contract research rule is worth depends on how much of that work goes to outside partners rather than on the total, and even on an SME budget every externally commissioned work package shifts the arithmetic.

Which Programme Suits Your Company?

Choose by financing logic rather than by programme name. Everything below assumes an SME under the EU definition, the standard case in our client work:

ZIM fits SMEs with clearly delineated projects

ZIM is the right instrument when an SME can describe one innovation project cleanly, plans a clear start and needs the money committed before work begins. That case has not disappeared, only parked: the programme announcement puts a reopening at early 2027, subject to the federal budget. Typical use cases:

• Mechanical engineering and production processes
• Automotive supply and hardware-focused deep-tech projects
• First-of-a-kind developments with defined milestones and a commercialisation path

The Research Allowance fits SMEs with continuous R&D

Innovation funding for SMEs through the Research Allowance pays off in companies with ongoing R&D, several teams and recurring development cycles. It is especially attractive in software and AI, biotech, medtech, climate and energy technology or complex engineering, wherever R&D is organised as a permanent core function.

Can ZIM and the Research Allowance be combined?

Yes, a combination works, but never as double funding of the same costs. The separation runs along projects or cost categories: ZIM for one tightly defined project, the Research Allowance for the rest of the in-house research in the portfolio. Before you combine them, check the aid ceilings, how the costs are split and the interaction with other grants, VC financing and state-level programmes.

The ZIM vs. Research Allowance Germany comparison rarely ends in an either-or. For most growing SMEs the Research Allowance is the more scalable base instrument, and ZIM complements it wherever a single project can be carved out cleanly and described early enough. While new ZIM applications are on hold, that base instrument carries the whole load, which puts clean R&D documentation ahead of any grant application on the to-do list.
