In Germany, not every home workspace is automatically accepted for tax deductions.
Before thinking about how much you can deduct, the tax office first asks a much more important question:
👉 Do you actually qualify for a “dedicated home office room” at all?
This guide helps you quickly understand whether your situation meets the legal requirements.

🎯 The Only Question That Matters
Is your workspace a separate room used almost exclusively for professional work?
This is the starting point for everything.
If you cannot clearly answer this with “yes”, you will usually not qualify for a dedicated home office room deduction.
🏠 Requirement 1: A Separate Room
The tax office only accepts a home office if:
- It is a fully separated, enclosed room
- It has a door
- It is part of your private living space
❌ Not accepted:
- Desk in the living room
- Corner in a bedroom
- Kitchen table workspace
- Open space or hallway setup
👉 If your workspace is not a real room, you will generally fall under the Home Office Flat Rate system instead.
🧭 Requirement 2: Almost Exclusive Use (90% Rule)
The room must be used almost entirely for work.
Allowed (professional use):
- Desk and computer setup
- Work documents
- Office equipment
Not allowed (private use):
- Guest bed
- TV for entertainment
- Storage for personal items
- Shared family space
👉 Even limited private use can create problems during a tax review.
🎯 Requirement 3: Center of Professional Activity (Mittelpunkt)
This is the most important test.
The question is:
Is this room the main center of your professional work?
Typically YES:
- Full-time freelancers working from home
- Self-employed professionals
- Remote workers without a workplace at an employer
Often difficult to qualify:
- Hybrid workers with a regular employer office
- Employees with a permanent workplace provided by the employer
- People whose main activity takes place outside the home
👉 The tax office focuses on where your work is professionally centered, not simply how many days you work from home.
⚠️ Important Reality Check
Even if you:
- Work many days from home
- Have a well-organized workspace
- Spend long hours working there
👉 It does NOT automatically mean you qualify.
The decisive factor is still whether the room is considered the professional center of your activity.

📋 Quick Eligibility Check
Ask yourself these three questions:
Q1: Do I have a fully separate room?
- No → You will generally use the Home Office Flat Rate
- Yes → continue
Q2: Is it used almost only for work (90%)?
- No → The room will usually not qualify
- Yes → continue
Q3: Is it the main center of my professional activity?
- No → You will usually fall under the Home Office Flat Rate system
- Yes → You may qualify for a dedicated home office room deduction
🧠 What If You Do NOT Qualify?
If you do not meet the conditions for a dedicated home office room, you can still claim:
- Home Office Flat Rate (€6 per day, max €1,260)
- Laptop and work equipment
- Internet costs (partial deduction)
👉 These do not require a separate room.
⚠️ The Home Office Flat Rate and the dedicated home office room deduction cannot be claimed for the same working day.
🧾 Key Takeaway
The home office room deduction in Germany is not mainly about how often you work from home.
It depends on:
- The physical structure of your workspace
- The exclusivity of professional use
- Whether the room is the professional center of your activity
If one of these conditions is missing, the tax office will usually place you in the Home Office Flat Rate system instead.
