Frequently Asked Questions

What is the Forschungszulage?

The Forschungszulage (Research Allowance) was introduced in 2020 under the Forschungszulagengesetz (FZulG). It provides a 25% tax credit on eligible R&D personnel costs, up to a maximum eligible expenditure of EUR 2 million per year (maximum credit: EUR 500,000). The credit is offset against the company's income or corporate tax.

What expenditure is eligible?

Eligible costs are primarily personnel costs for employees working on qualifying R&D projects (basic research, applied research, or experimental development). Contract research costs are eligible at 60% of the invoiced amount. The R&D project must be certified by the Bescheinigungsstelle Forschungszulage (BSFZ).

Can all companies claim the Forschungszulage?

Yes. Unlike many other R&D incentives, the Forschungszulage is available to all companies subject to German income or corporate tax, regardless of size, industry, or profitability. Even loss-making companies can receive the credit as a cash payment if it exceeds their tax liability.

Understanding R&D Tax Credits in Germany

The Forschungszulage, who qualifies, and how much you can claim

What is the Forschungszulage?

The Forschungszulage is a tax credit for research and development activities introduced in 2020. Companies receive 25% of eligible R&D personnel costs back as a tax credit. The maximum eligible amount is €4 million per year, giving a maximum credit of €1 million. Unlike a deduction, it directly reduces your tax bill euro for euro.

Who can claim the Forschungszulage?

All companies in Germany can claim it, regardless of size or industry — from a one-person startup to a large corporation. Sole traders, partnerships, and corporations all qualify. You must conduct R&D activities that are new or significantly improved products, processes, or services. The R&D must involve systematic investigation or experimentation.

What costs are eligible?

Eligible costs include wages and salaries of employees directly working on R&D projects, plus 15% flat rate for overhead costs. For contract research (Auftragsforschung), 60% of the contract value is eligible. A company with 3 researchers earning €70,000 each has eligible costs of €210,000 × 1.15 = €241,500, giving a Forschungszulage of about €60,375.

How do you apply?

The process has two steps. First, apply to the Bescheinigungsstelle Forschungszulage (BSFZ) for certification of your R&D project. They confirm your project qualifies. Second, claim the credit in your annual tax return (Anlage FZ). The BSFZ decision typically takes 3-4 months. You can apply retroactively for up to 4 years.

Can startups and loss-making companies benefit?

Yes, this is a key advantage. If your Forschungszulage exceeds your tax bill, the excess is paid out as a cash refund. A startup with no profits that spends €200,000 on qualifying R&D staff gets a €50,000 cash payment from the Finanzamt. This makes it one of the most startup-friendly R&D incentives in Europe.

Can you combine it with other R&D funding?

Yes, the Forschungszulage can be combined with other public funding programmes like ZIM, BMBF grants, or EU Horizon Europe. However, costs funded by other programmes cannot be double-counted. If a researcher is 50% funded by a ZIM grant, only the remaining 50% of their salary qualifies for the Forschungszulage.
