Apply for Research Allowance Germany: Guide 2026

The R&D tax allowance (Forschungszulage) has been Germany's central R&D funding instrument since January 2020, and the legislative amendments of 2024 and 2025 have made it considerably more attractive. Anyone applying for the Research Allowance in Germany gets a non-dilutive, non-repayable liquidity advantage that combines with grants, venture capital or bank financing. This guide shows how the process works in practice in 2026.

What Is the Research Allowance and Who Can Apply?

The Research Allowance is a direct tax credit under the Research Allowance Act (FZulG). It is credited against income or corporation tax, and any surplus is paid out, which is what makes it work for companies with no current profits.

Who Receives the Research Allowance?

Every company subject to tax in Germany qualifies: corporations, partnerships, sole traders and startups with no profit history. Size, legal form and industry make no difference, provided there is an eligible R&D project and qualifying expenditure behind the claim.

Since the Wachstumschancengesetz (Growth Opportunities Act), SMEs receive 35 percent of the eligible assessment basis for expenditure incurred after 27 March 2024, large enterprises 25 percent. For an SME, the Research Allowance is the most direct lever on liquidity there is.

Which R&D Projects Are Eligible?

The FZulG funds basic research, industrial research and experimental development, as the OECD Frascati Manual defines them. What matters is demonstrable technical or scientific uncertainty, not innovation buzzwords.

What stays outside the definition:

• Routine programming and plain product maintenance
• Standard integration and customising with no research content
• Series development that carries no technical uncertainty

Software and AI, deep tech, biotech and pharma, automotive, mechanical engineering and energy tech come up most often, although the law itself names no sectors at all.

The Two-Stage Application Process at a Glance

The Research Allowance application process runs in two clearly separated stages: the BSFZ reviews whether the project is research at all, and the tax office then assesses the money. Confuse the two levels and you buy yourself follow-up queries and delays.

Step 1: Apply for R&D Certification at the BSFZ

The Bescheinigungsstelle Forschungszulage (BSFZ), the certification body, handles the technical review of the project. The application for R&D certification runs entirely through the BSFZ web portal.

A project description that holds up covers:

• The state of the art and the technical problem you identified
• Your own solution logic and the methods behind it
• Milestones and termination criteria
• Why the outcome was genuinely open when the project started

CTOs and R&D leads should not hand the description to finance and walk away. For software projects, architecture limits, model validation or scaling problems carry far more weight with the reviewers than general claims about innovation.

Step 2: Submit the Research Allowance Application at the Tax Office

Once the BSFZ certification is in hand, the Research Allowance application goes to the tax office through Mein ELSTER. It is filed per financial year on the basis of expenditure actually incurred, so the timing follows the books rather than the project plan.

Plan the timing realistically: several weeks for the BSFZ review, then further weeks to months until the tax assessment. Without the BSFZ decision the tax office cannot assess anything at all.

Applying for the Research Allowance via Mein ELSTER

Mein ELSTER is where the payout is actually triggered. After certification, companies report the eligible expenditure of the completed financial year in the electronic form. Since the Growth Opportunities Act (March 2024), eligible costs include:

• Taxable wages of the R&D team
• Owner-performed R&D by sole traders and partners in a partnership (Mitunternehmer), at a flat EUR 100 an hour for activities from 1 January 2026 and EUR 70 an hour for activities between 28 March 2024 and 31 December 2025, capped at 40 hours a week
• Contract research, with 70 percent of the fee claimable for contracts placed after 27 March 2024, 60 percent for earlier ones
• A 20 percent overhead flat rate on the remaining eligible expenditure, available from 2026 for projects that start after 31 December 2025 under the Tax Investment Stimulus Programme
• Depreciation on certain movable capital assets, new since March 2024

Structure and Modules of the Application Form

The ELSTER form is built in modules, and a typical application uses these:

• Company details and tax reference number
• Eligible project with BSFZ certification number
• Internal personnel costs with time records
• Contract research with contract references
• Owner-performed R&D, for sole traders and partners in a partnership only

Not every module applies to every company. The structure follows the audit trail through tax, payroll and project controlling, which is also the order in which a reviewer reads it.

Prepare the data in this order:

• Verify BSFZ certification and project ID
• Reconcile personnel lists, time records and payroll totals
• Document contract research agreements and invoices separately

When to Apply, and How Far Back You Can Go

The BSFZ certification can be applied for before, during or after the project, up to four years retroactively. The tax assessment through ELSTER always comes after the end of the financial year, and the tax office can still assess a claim up to four years after the end of the year in which it arose. Applying for the Research Allowance retroactively therefore works for as long as those two windows are open. The instrument has run since 2020, but it is the four-year limits, not the start of the programme, that decide which years you can still reach.

Take an AI startup with 10 employees and a full development year behind it:

Item - Amount

Eligible R&D wages: EUR 800,000

Contract research, gross: EUR 200,000

Of which claimable at 70 percent: EUR 140,000

Total assessment basis: EUR 940,000

Research Allowance at the SME rate of 35 percent: EUR 329,000

Research Allowance Amount and Tax Effect

The funding ceiling rose sharply with the Tax Investment Stimulus Programme (July 2025). For expenditure from 2026 the maximum assessment basis is EUR 12 million per financial year, which puts the maximum Research Allowance for an SME at EUR 4.2 million, 35 percent of EUR 12 million.

The allowance is credited in full against the income or corporation tax assessed next, and only a remaining surplus is refunded, which is what makes it valuable to loss-making startups.

Specifics for Large Enterprises and Technology-Neutral Development Projects

Large enterprises receive 25 percent of the assessment basis, up to EUR 3 million a year. The Research Allowance stays strategically relevant for them because it prescribes no thematic funding framework and no submission deadlines.

An automotive supplier, a semiconductor manufacturer and a software house are all measured against the same R&D criteria, provided the project carries genuine technical uncertainty. Unlike grants or venture capital, the Research Allowance is non-dilutive and non-repayable.

In practice, large industrial groups run the allowance as a permanent part of their research financing and combine it with direct project grants, and that combination scales down well: the allowance covers the in-house R&D payroll, while the grant funds the collaborative part of the same project. The one hard limit is that the same expenditure cannot be funded twice, so costs already covered by a grant or any other state aid drop out of the assessment basis under Section 7 (2) FZulG.

Correctly Accounting for and Recognising the Research Allowance

How do you recognise the Research Allowance in the accounts? Under commercial law the item on the balance sheet is the sufficiently concrete refund claim, never the intangible R&D result behind it. Three conditions have to hold: the balance sheet date falls after the claim arises, the evidence stands up, and the assessment is sufficiently probable.

For booking and accounting for the Research Allowance the rule is unglamorous: without solid project delineation, a BSFZ certification and traceable cost accounting, nothing should be recognised at all. Many companies wait for the assessment notice before they book the claim, which matters most in statements that go to investors or banks.

Section 10 FZulG governs the tax crediting itself. The commercial balance sheet treatment follows the general HGB principles for recognising receivables, and the two questions are decided separately.

Practical Tips and Typical Mistakes with the Research Allowance

Most rejections arise not from an insufficient level of innovation but from unclear R&D delineation. The BSFZ sets out what it expects in its audit guide (Prüfleitfaden), and in practice the follow-up queries land on the descriptions that never say what was technically uncertain at the start.

Typical errors:

• Declaring routine development as research
• Claiming personnel costs without time records
• Drafting contract research agreements without a clear R&D scope
• Classifying implementation work as experimental development

The companies that get through the BSFZ review without a round of queries tend to keep a short standing profile for every R&D project: what was uncertain at the start, which milestones were set, and where the work stops being research and turns into series development. That profile is the BSFZ application in draft form.
