Home Office Tax Deduction in Germany 2026: Arbeitszimmer Rules for Freelancers and GmbH Directors

If you work from home in Germany, you've probably wondered: can I deduct my home office? The answer depends on whether you qualify for a full Arbeitszimmer (dedicated home office room) or whether the simpler Homeoffice-Pauschale flat rate applies to your situation.

Arbeitszimmer: When Is a Home Office Fully Deductible?

Under §4 Abs. 5 Nr. 6b EStG, a home office room is fully deductible if it forms the center (Mittelpunkt) of your entire professional activity. Since the 2023 tax reform, there is no longer a €1,250 annual cap — the full proportional costs can be claimed. This applies to:

• Freelancers (Freiberufler) and self-employed traders (Gewerbetreibende) whose primary workplace is at home
• GmbH managing directors when the home office is the primary place of work and no adequate company office is available

Key requirement: the room must be used almost exclusively for business purposes. A guest bed or shared use immediately disqualifies the deduction.

How Much Can You Deduct?

With a qualifying Arbeitszimmer, you can deduct a proportional share of:

• Rent (Kaltmiete) or building depreciation (for owners), proportional to floor area
• Utilities: electricity, heating, water, internet — proportional share
• Cleaning costs for the office room
• Furniture and fittings (potentially via depreciation over useful life)

Example: office room is 20 m² in a 100 m² apartment (20%). With €2,000/month rent, that's €400/month deductible — €4,800 per year.

Homeoffice-Pauschale: The Simpler Alternative

If you don't qualify for (or don't want to claim) a full Arbeitszimmer, you can use the Homeoffice-Pauschale flat rate:

• €6 per day on which you work exclusively from home
• Maximum €1,260 per year (210 days)
• Permanently available since 2023 — no dedicated room required, just a record of home-working days
• For freelancers: claimed in Anlage EÜR; for employed managing directors: in Anlage N

Special Rules for GmbH Managing Directors

If you're a shareholder-director with no full company office, you have two options:

• Rent agreement between GmbH and yourself personally: You rent a room in your private apartment to the GmbH at market rates. The GmbH deducts the rent as a business expense; you report rental income. Advantage: no Arbeitszimmer complexity in your personal income tax. The contract must be in writing and at arm's length.
• Personal income tax deduction: If the Arbeitszimmer qualifies as your primary workplace (Mittelpunkt), you can claim it in your personal tax return — but only there, not at the GmbH level.

What Doesn't Qualify as an Arbeitszimmer?

The tax office will not accept:

• A desk in a corner of the living room or bedroom
• A room also used as a guest room, hobby room, or storage
• A room with any regular private use, even occasional

Conclusion

The choice between the full Arbeitszimmer and the Homeoffice-Pauschale depends on your situation. For freelancers who primarily work from home, the full deduction is usually far more valuable. For everyone else, the flat rate is simpler.
