Research Allowance for Startups Germany (2026)

The Research Allowance (Forschungszulage) is not a grant you compete for, it is a tax entitlement. Whatever the tax office assesses is credited in full against your next income or corporation tax assessment, and anything left over after that is refunded. In a loss-making growth phase that remainder is the whole point, because it turns part of a research budget back into cash.

The Research Allowance Act (FZulG) as the Legal Basis

The Research Allowance Act (FZulG) has been in force since 1 January 2020, and it gives any company with a tax residence or a taxable permanent establishment in Germany a legal entitlement to support for eligible research and experimental development. There is no competition behind it and no discretionary decision: if the project and the costs qualify, the money follows. From 2026, the version that applies is the one widened by the Growth Opportunities Act (March 2024) and the tax investment stimulus programme (July 2025).

Two bodies decide, in a fixed order. The BSFZ (Bescheinigungsstelle Forschungszulage, the certification body) rules on whether the work counts as research at all; only then does the tax office look at the costs, assess the allowance and set it against your tax.

Who Qualifies for the Research Allowance?

Corporations, partnerships, sole traders and spin-offs all qualify, provided they are registered for tax in Germany. Age is beside the point here: a company incorporated last quarter has the same entitlement as a manufacturer that has been filing accounts for decades. What counts is the quality of the project.

What does not qualify:

• Pure product maintenance and bug fixing
• Standard software, customising, regular rollout
• Quality assurance in daily operations
• Scale-up without technical risk

Only projects that systematically produce new technical knowledge, or resolve genuine technical uncertainty, are eligible.

Funding Amount and Assessment Basis for Startups at a Glance

How much liquidity actually arrives depends on two figures: the funding rate that applies to you, and the assessment basis the law allows. Both have been widened considerably, first by the Growth Opportunities Act in 2024 and then by the tax investment stimulus programme in 2025.

Standard Rate and the Higher Rate for Startups

The standard rate is 25%, and that is what larger enterprises get. SMEs, a category that covers most startups and founder-led companies, claim the higher rate of 35%. Take a 10-person AI startup with EUR 800,000 of eligible personnel costs: that comes to EUR 280,000 of Research Allowance for a single financial year.

The money costs no equity, unlike a VC round, and creates no repayment obligation, unlike a loan. Which is why founders tend to run the allowance alongside grants and equity rather than instead of them.

Retroactive Claims: Older Projects Count Too

You can still claim for earlier years, as long as the assessment deadline for that financial year is open. In 2026 that usually means the financial years from 2022, while the project itself may well have started earlier, since everything from 1 January 2020 is covered. The BSFZ certificate is needed for those years too. Plenty of companies raise cash this way out of development cycles or pilot projects they finished long ago.

Step by Step: How Startups Apply for the Research Allowance

A claim that goes through cleanly is usually the work of four people talking to each other: the CTO, whoever runs R&D, finance and the tax adviser. What they have to produce is a clear project boundary, time records that hold up, and costs traceable line by line from payroll, ERP and contracts.

Step 1: Apply for the Eligibility Certificate

At the BSFZ you describe the objective, the starting position, the technical risk and the systematic route to a solution. The applications that go through without a query make one thing obvious early: why the solution was not already part of the state of the art.

A submission that works includes:

• Work packages and milestones
• Who does what, and what the prototype is meant to prove
• A clear line between the project and routine development

The BSFZ judges the technical core of the project, not its business case. Depending on complexity, expect several weeks to a few months.

Step 2: File the Claim with the Tax Office

Once the certificate is in, the claim goes to the tax office, electronically through ELSTER and only after the financial year has ended. What you claim are the eligible costs actually incurred in that year.

Without a solid cost matrix, by project, person, period and receipt, the risk of queries rises sharply. Treat the allowance as a reliable but delayed inflow: the money does not land in the same quarter you file.

Step 3: Assessment and Crediting Against Your Tax

Once assessed, the Research Allowance is credited in full against your next income or corporation tax assessment, and any remainder is refunded. While that tax return is still outstanding, the tax office will also reduce your current prepayments on request. Both work in a loss-making year, and that is what makes the instrument valuable to a growing startup.

Eligible Costs: What Counts for the Research Allowance?

With eligible costs, the documentation decides what is paid out. The tax office does not check technical plausibility, that is the BSFZ's part; the tax office wants to see which people, contracts and assets are directly attached to the certified project.

Personnel Costs as the Central Assessment Basis

Personnel costs carry most claims. What qualifies is the pay of everyone working directly on the project, as far as it is subject to payroll tax. Founders and managing directors doing technical work count as well, as long as their project hours are documented separately from management and sales.

Where the line falls depends on the industry:

• Software and AI: architecture, model training, the evaluation of novel methods and experimental data pipelines qualify. App development, bug fixing, standard integrations and day-to-day operations do not.
• Deep tech, biotech, mechanical engineering: laboratory work, simulation, prototyping, test series. Hour-based project records are mandatory here, and blanket estimates are one of the more common reasons for rejection.
• Contract research: 70% of the fee paid to a qualified contractor counts, provided the contract was awarded after 27 March 2024; for contracts awarded earlier it is 60%. The contract chain, the project reference and the absence of double funding all have to be documented.

Your Own Spending as the Precondition for the Maximum

The maximum allowance of EUR 4.2 million, for SMEs and for expenses incurred from 2026, presupposes demonstrable spending of your own on a matching scale. Since 2024, investment in movable capital assets has counted for more, which is what makes the difference for semiconductors, robotics, measurement technology or laboratory equipment. Procurement, capitalisation and project allocation therefore belong on the tax team's desk early, not in the last week of the financial year.

Practical Examples: How Companies Document Their R&D

BioNTech shows the order of magnitude these rules are built for: the company spends billions on research every year and reports its R&D expenditure to international standards. Anyone documenting at that level already has the basis for tax-based funding in place.

It is a similar picture at TRUMPF, the mechanical engineering and laser technology manufacturer: the group reports annual R&D spending in the hundreds of millions of euros. For the allowance, what matters is less the total than how it breaks down by project and cost centre, and that is a question of bookkeeping discipline rather than of size.

Common Errors, and What They Actually Cost

The usual failure is not a thin innovation story, it is a blurred boundary. Mix routine work with research, or report costs without evidence behind them, and you invite queries or a correction later.

Avoiding Double Funding

Double funding is the audit point everything turns on: the same costs must not be financed by another subsidy and claimed through the Research Allowance at the same time. Combining the two is possible, as long as cost types, periods and work packages are kept properly apart.

In practice, draw up a single funding overview before you apply, recording for each work package which wages, external services and material costs have been claimed or approved where. It earns its keep the moment BMFTR grants, state programmes or EU projects are in the mix.

Reconcile the Assessment Notice with Other Applications

When other funding is applied for in parallel, the Research Allowance assessment notice, and ideally the BSFZ certificate before it, should be reconciled with the rest of the paperwork. That keeps the project description, the cost approach and the state aid presentation from contradicting each other, and the same consistency pays off again in due diligence with investors and auditors.

By international standards the German instrument is generous: on the OECD data for R&D tax incentives, Germany now sits in the upper third of OECD countries for effective SME funding intensity, a result of the reforms since 2024.

Conclusion: Deploy the Research Allowance for Startups Strategically

From 2026, the Research Allowance for startups in Germany is a dependable part of the financing mix: SMEs get 35% of their eligible costs, the assessment basis runs to EUR 12 million, and the maximum allowance is therefore EUR 4.2 million per financial year.

So take the project portfolio for the financial years still open, put the ongoing R&D documentation on a footing that survives a query, and plan the allowance into your budget and cash forecast. Structure the time tracking, the project boundaries and the cost logic early, and the R&D tax incentive in Germany works reliably and in full.
