What is the EXIST founder grant?
EXIST is a German federal funding programme for founding teams from universities and research institutions, typically running twelve months for up to three people. It consists of two components treated very differently for tax: the personal stipend and the material cost allowance paid to the institution.
The EXIST-Gründerstipendium is a funding programme run by Germany's Federal Ministry for Economic Affairs. It supports founding teams from universities and research institutions during the early development phase — typically for twelve months, with up to three funded individuals per team.
The funding consists of two components with fundamentally different tax treatment:
EXIST-Forschungstransfer is a separate, more advanced programme for projects with greater technological maturity, running in two phases. The tax treatment is structurally similar but differs in detail — particularly because GmbH incorporation often occurs earlier and parts of the funding flow at company level. This guide covers the standard EXIST founder grant only.
Is the EXIST grant tax-free?
No. The exemption under § 3 Nr. 44 EStG does not apply because the grant serves the founding of a business — an economic purpose — rather than research or academic training. The Federal Fiscal Court confirmed this in its ruling of 25 March 2021 (VIII R 47/18); the tax authorities follow this view.
The common assumption: Section 3 No. 44 of the German Income Tax Act (EStG) exempts stipends that promote research and scientific training from income tax. This sounds applicable — but it does not apply to EXIST.
Section 3 No. 44 EStG requires that the stipend serves exclusively scientific or artistic training or research, and that the recipient is not required to provide an economic return. The EXIST founder grant serves business creation — an economic purpose — and the founding team commits to using the funded period to develop a company.
The BFH case law — starting with ruling III B 128/11 and confirmed in judgment VIII R 47/18 of 25 March 2021 — has established that the tax exemption under Section 3 No. 44 EStG does not apply to the EXIST founder grant. The grant is taxable. The precise allocation to an income category has not been finally resolved by the BFH; the tax authorities (including OFD Frankfurt) regularly classify the EXIST grant paid in monthly instalments as recurring income under Section 22 No. 1 EStG.
How is the grant taxed?
Where paid monthly, the tax authorities generally classify the grant as a recurring payment under § 22 Nr. 1 EStG — other income, declared in Anlage SO. The personal income tax rate applies. With no other income, the basic allowance of €12,348 (2026) provides relief.
The EXIST grant is regularly classified by the tax authorities as recurring income under Section 22 No. 1 EStG — miscellaneous income under German tax law. It is declared in the annual income tax return using the supplementary form for miscellaneous income (Anlage SO).
Tax rate
The personal income tax rate applies — no preferential rate, no flat withholding tax. Recipients who have no other significant income during the EXIST year benefit from the basic tax-free allowance (Grundfreibetrag — €12,348 in 2026). Depending on the grant amount and personal circumstances, the effective tax burden can therefore be modest — or in some cases zero.
Married recipients
Married recipients can benefit from joint assessment (Ehegattensplitting) if their spouse has their own income — this can significantly reduce the overall tax burden.
How much of the grant remains after tax? The EXIST calculator on startuptax.io works through the numbers — including the basic allowance, deductible expenses, and the joint assessment option.
Which expenses are deductible?
Not just the €102 flat rate. For other income under § 22 Nr. 1 EStG, the taxable amount is the excess of income over actual expenses. Anyone who can document higher actual costs — work equipment or travel, for example — should claim them.
Contrary to a common oversimplification, the deduction is not limited to the €102 flat expense allowance. Under Section 22 No. 1 EStG, taxable income is calculated as receipts minus actual deductible expenses. Where actual expenses exceed €102, they can be claimed.
What may be deductible — the following list is not exhaustive:
- Work equipment purchased personally and paid for out of pocket — to the extent not covered by the university's project cost allowance
- Travel costs to customers, partners, or conferences paid personally
- Home office flat rate: €6/day, up to €1,260/year (applicable since 2023)
- Professional literature, memberships in relevant associations
- Necessary training or professional development directly related to the funded activity
- Other expenditure with a direct connection to the grant activity
Costs already covered by the university's project cost allowance cannot be claimed again as personal deductible expenses — no double deduction. In practice, personal deductible expenses are often limited in scope, but they are not zero. Keep receipts and review what can legitimately be claimed.
How is the material cost allowance treated?
The material cost allowance is paid to the institution, not to the founders, and is therefore generally not taxable income for them. It becomes relevant for tax only if equipment financed from it remains with the founders after the funding period or is transferred into the GmbH.
The project cost allowance (Sachkostenpauschale) flows directly to the university or research institution — not to the founders personally. It is therefore not taxable income for the founders.
It becomes relevant if equipment or other assets purchased via the allowance remain with the founders after the grant period ends or are transferred into a GmbH. Depending on the specific circumstances, this could constitute a taxable benefit. This should be clarified with the university and a tax advisor on a case-by-case basis.
What happens with health insurance?
EXIST recipients are generally not in employment subject to social security. Anyone previously covered by family insurance loses that status once the grant exceeds the income threshold. Voluntary statutory or private cover then becomes necessary — the cost belongs in the budget from the outset.
A frequently overlooked point: EXIST grant recipients are generally not in a social insurance-paying employment relationship. Those who were previously covered as a family member under a parent's or partner's statutory health insurance will lose that cover if the grant exceeds the income threshold for family co-insurance. Personal health insurance — either voluntary statutory or private — then becomes mandatory. These costs should be factored in from the outset and can be deducted as special expenses in the tax return.
Do I need a tax advisor for this?
Not necessarily. The classification is clear and the relevant items are manageable; Anlage SO can be handled with standard tax software. That assumes you understand what is taxable and which expenses qualify. Where there is parallel income or the classification is unclear, professional support is worthwhile.
Not necessarily. Founders who familiarise themselves with the basics can in many cases prepare their personal income tax return for an EXIST year themselves. The classification is clear, the relevant items are manageable, and standard tax software handles the miscellaneous income section (Anlage SO) straightforwardly.
What matters is understanding the topic — what is taxable, which expenses are deductible, and which entries go where. Getting this wrong risks errors that the tax authority will correct — with back payments and interest.
A tax advisor makes sense when the personal situation is more complex: simultaneous GmbH incorporation, other income streams, international circumstances, or uncertainty about how to classify specific items correctly.
Practical notes on the tax return
Where classified under § 22 Nr. 1 EStG, the grant belongs in Anlage SO. All personally borne expenses connected with the funded activity should be documented. Importantly, the tax office may set advance payments after the first assessment — the liquidity for this should be planned in.
- Anlage SO: Where the grant is classified as recurring income under Section 22 No. 1 EStG, it is declared in the miscellaneous income supplement (Anlage SO). The classification in the individual case should be agreed with the responsible tax office or a tax advisor.
- Keep records: Document all personally incurred expenses connected with the grant activity — receipts, bank statements, mileage records where relevant.
- Advance tax payments: The tax authority may set quarterly advance income tax payments once the expected liability exceeds a threshold. This can happen retroactively after the first return is filed. Getting an overview early avoids unexpected liquidity pressure.
- Filing deadline: Generally 31 July of the following year. With a tax advisor, the deadline extends significantly.
- Health insurance contributions: Enter as special expenses (Sonderausgaben) — this reduces the tax liability further.
Enter your own numbers and model the tax burden — including deductible expenses, basic allowance, health insurance, and the joint assessment option.
