The Essentials at a Glance

Yes, you can apply for Germany's research allowance without a consultant. Both stages are open to every company: the BSFZ application and the tax office application (Anlage FZ). A first application realistically takes 40–80 working hours. The allowance is 25 % of eligible expenses, 35 % for SMEs on request, on up to €12 million assessment basis – a maximum of €4.2 million per year. In 2024, some 29 % of BSFZ projects were rejected, mostly over weakly substantiated Technical Risk.

Can You Apply for the Research Allowance Yourself?

Yes – entirely. The Research Allowance Act (FZulG) has no consultancy requirement: every eligible company can complete both stages of the procedure in-house. The BSFZ reviews DIY applications against exactly the same criteria as professionally prepared ones.

“There is no consultancy requirement. The difference is not admissibility – it is effort and rejection risk.”

The procedure has two stages – you can handle both yourself:

Stage 1: BSFZ Application

Technical project description in the BSFZ portal: demonstrate novelty, Technical Risk, and systematic approach. The BSFZ reviews substantive eligibility.

Stage 2: Tax Office Application

After certification: file Anlage FZ via ELSTER. The tax office assesses the allowance and offsets it against your tax liability – any surplus is paid out.

The funding level does not depend on who files: 25% of eligible expenses, 35% for SMEs on request (a 10-percentage-point increase, Section 4 FZulG). Assessment basis since 01.01.2026: €12 million per year (27.03.2024–31.12.2025: €10 million); maximum allowance: €4.2 million per year.

Our honest assessment: With one clearly delineated R&D project and time available, DIY is realistic – you do not need a consultant, not even us. It gets critical with multiple projects, contract research, or retroactive claims.

How Much Effort Is the Application, Really?

The honest answer: more than most expect. Plan 40–80 internal working hours for a first application with one R&D project – realistic distribution per stage from our application practice:

Task Stage Realistic Effort
Identify & delineate R&D projects Preparation 8–15 hrs
Write the BSFZ project description Stage 1 (BSFZ) 15–30 hrs per project
Register & submit in the BSFZ portal Stage 1 (BSFZ) 2–4 hrs
Complete Anlage FZ via ELSTER Stage 2 (tax office) 4–8 hrs per fiscal year
Ongoing time tracking & documentation Continuous 1–2 hrs per week
Queries from BSFZ or tax office Both stages 4–10 hrs

What drives the effort up

  • Multiple projects: Effort scales almost linearly per project description.
  • First application: The BSFZ-criteria and portal learning curve hits hardest once.
  • Retroactive years: Documentation must be reconstructed – often the largest item.
  • Contract research: Contracts need review – 70% of the fee is eligible.
Relief since 2026: For eligible expenses from 01.01.2026, the 20% flat overhead allowance applies (Section 3 (3b) FZulG) – overhead needs no itemized proof, noticeably reducing documentation effort.

When Does DIY Make Sense?

Three factors decide whether DIY pays off: how clearly your R&D project is delineated, how much time you have, and how comfortable you are with tax forms. Three typical constellations:

Team working on a DIY application
DIY Works Well

Constellation 1: One Project, Clear Delineation, Time Available

A single R&D project with genuine technical novelty – a new algorithm, a new process, a prototype. Then the DIY application is realistic:

  • R&D delineation: Clear-cut – the project has recognizable Technical Risk
  • Tax know-how: Available in-house, or your accountants handle Anlage FZ
  • Time budget: 40–80 hours are planned and affordable
  • Documentation: Technical records and time tracking already exist

Borderline

Constellation 2: Multiple Projects or Unclear Delineation

Your development blends into day-to-day business, you have several projects, or contract research is involved. Effort rises sharply – and with it the error risk:

  • R&D delineation: Laborious – routine work must be cleanly separated out
  • Effort: 15–30 hours of project description per project, quickly adding up
  • Typical stumbling block: Contract research (70% of the fee) allocated incorrectly
  • Recommendation: At least one external quality check before submission
Complex paperwork on a desk
Consider Consulting

Constellation 3: Complex Structure, High Amounts, No Time Budget

Affiliated companies, retroactive applications over several years, or simply: nobody has 40–80 hours to spare. Here the DIY application costs more than it saves:

  • Complexity: SME definition in a group, multiple fiscal years, mixed projects
  • Error cost: With high assessment bases, every overlooked item weighs heavily
  • Opportunity cost: R&D leads and management tied up for weeks
  • Alternative: Success-based consulting – no approval, no fee
Frankly: If you are in constellation 1, you do not need a consultant – use the free resources further down, they cover the entire DIY application. A consultation only becomes worthwhile from constellation 2 onwards.

Where Do DIY Applications Fail Most Often?

In 2024, around 29% of BSFZ projects were rejected. From more than 25 supported engagements, we know the five mistakes that repeat most often:

1 Technical Risk not substantiated. The application describes what was developed – but not why the solution path was uncertain. That is exactly what the BSFZ reviews, alongside novelty and systematic approach. By far the most common rejection reason.
2 R&D delineation too broad. The entire development project is submitted instead of the R&D core. Routine work in the application leads to cuts – or drags the whole project into rejection.
3 Assessment basis left unused. The 20% overhead allowance (for eligible expenses from 01.01.2026) is not claimed, contract research (70% of the fee) is overlooked, or the own-contribution rate for sole proprietors (€100 per working hour, max. 40 hrs/week) is forgotten.
4 Time tracking starts too late. R&D hours are not documented project-based and continuously. Reconstructed timesheets rarely survive a tax audit.
5 BSFZ certification and Anlage FZ do not match. Projects, periods, or costs differ between stage 1 and stage 2 – provoking tax office queries and delaying payout by months.
The good news: All five mistakes are avoidable once you know them before submission. Our application example with wording guidance shows what a convincing project description looks like.

What Does a Mistake Cost Compared to Consulting?

The decisive calculation is not “fee saved” but “error cost avoided”. A rejected project, an understated assessment basis, or missing time tracking cost real money – sometimes permanently:

Mistake Typical Consequence Fixable Afterwards?
BSFZ rejection due to a weak project description Claim for the project lost; appeal or new application costs 3–6 months Partly – appeal and re-application are possible
Overhead allowance not claimed 20% of personnel costs missing from the assessment basis – every single year Yes, as long as the assessment can be amended
Contract research allocated incorrectly Cut by the tax office, or the 70% of the fee goes unused Partly – depends on the procedural stage
Time tracking missing or started too late Cuts in a tax audit, in the worst case clawback Hardly – difficult to heal retroactively

For scale: since 2026, SMEs can reach effectively up to 42% of personnel costs (35% funding rate on 120% assessment basis thanks to the 20% overhead allowance) – miss the allowance and you give up that lever in every funding year. On the other side, reputable FZulG consulting typically works success-based. At NOVARIS that means: no upfront costs – if no allowance is approved, you pay nothing.

The most expensive mistake is not the rejection itself – that can often be repaired via appeal or re-application. It is the silently understated assessment basis: nobody notices it, it is never corrected, and it repeats year after year.

DIY or Consulting: The Direct Comparison

DIY Application
Your time instead of a fee
vs
OR
Specialized Consulting
Success-based, no upfront costs

Both routes lead to the same allowance – the difference lies in time, risk, and how fully the assessment basis is used:

DIY Application
No fee – the full allowance stays in the company
FZulG know-how is built up in-house
Full control over content and timing
Realistic for one clearly delineated project
40–80 hours of internal working time
Higher rejection risk without BSFZ routine
Assessment basis often left incomplete
Learning curve for Frascati criteria and portal
Specialized Consulting (NOVARIS)
BSFZ routine and proven wording practice
Assessment basis fully used (allowances, contract research, own contributions)
Few internal hours: interviews instead of writing
Retroactive application including reconstruction
Success-based – no approval, no fee
100% approval rate across all engagements
Success-based remuneration if approved
External insight into your R&D projects required
Rule of thumb: One project, clear delineation, time available – do it yourself. Multiple projects, contract research, retroactive years, or no 40 hours to spare – a free initial consultation clarifies in 30 minutes whether consulting pays off for your case.

The DIY Application in 5 Steps

This order has proven itself – each step links to the matching free resource.

1
Delineate Your R&D Projects

Check each project against the three criteria: novelty, Technical Risk, systematic approach. Only the R&D core counts – routine development stays out. The application example provides orientation.

2
Write the Project Description

Write for the BSFZ: What was technically uncertain? Which solution paths were investigated systematically? Mind the portal's character limits – the portal walkthrough explains every field.

3
Submit the BSFZ Application

Via the BSFZ portal, signing in with an ELSTER organization certificate. Processing takes about 3 months on average. The certification then acts as a binding base ruling for the tax office.

4
Time Tracking from Day One

Document project-based R&D hours continuously – not retroactively. Templates and requirements: time tracking. Own contributions: €100 per working hour, max. 40 hrs/week.

5
File the Tax Office Application

After receiving the certification, file Anlage FZ via ELSTER – separately per fiscal year. The allowance is offset against the next tax assessment; any surplus is paid out. All forms: forms overview.

Stuck at step 2? That is the most common exit point. An initial consultation with NOVARIS is free – since 2021 we have filed €18.85M in funding volume with a 100% approval rate. Book a call.

Frequently Asked Questions

Yes. There is no consultancy requirement – every eligible company can complete both stages itself: the BSFZ application via the BSFZ portal, followed by the tax office application via Anlage FZ in ELSTER. The difference is not admissibility but effort and rejection risk: around 29% of BSFZ projects were rejected in 2024, often over weakly substantiated Technical Risk.
Plan 40–80 internal working hours for a first application with one project: R&D delineation (8–15 hrs), BSFZ project description (15–30 hrs), portal submission (2–4 hrs), Anlage FZ via ELSTER (4–8 hrs), plus ongoing time tracking. BSFZ processing then takes about 3 months on average; payout follows with the next tax assessment.
The Technical Risk is not substantiated. Many DIY applications describe what was developed – but not why the solution path was technically uncertain. That is exactly what the BSFZ reviews, alongside novelty and systematic approach. Second place: assessment basis left unused, such as the 20% overhead allowance (for eligible expenses from 01.01.2026) or the 70% rate for contract research.
Yes, at any time and in any phase: before submission for quality assurance, after a BSFZ rejection for an appeal or new application, or between stage 1 and stage 2 to optimize the assessment basis. Retroactive correction is possible as long as the tax assessment can still be amended. NOVARIS works success-based – reviewing an existing DIY application costs nothing if no additional allowance results. Our consultant comparison shows which providers are suited for this step.
The BSFZ application is by far the higher hurdle. You must argue in free text why your project meets novelty, Technical Risk, and systematic approach – within the portal's character limits. The tax office application (Anlage FZ) is a structured form: demanding when calculating the assessment basis correctly, but manageable if time tracking and personnel costs are cleanly documented.

Why Self-Applications Fail

The FZulG application process is technically complex and full of pitfalls. BSFZ rejections, faulty cost allocations, and missed deadlines cost German companies millions in unclaimed funding every year.
