The home office deduction: when can you claim your workspace?

Working from home sounds like it should be tax-efficient — you already pay for the space, so why not deduct it? The Dutch tax authority has a different idea. The rules around home office deduction are notoriously strict: most home-based freelancers cannot deduct the room itself. But you can deduct furniture, equipment, and utilities. Here's exactly where the line is drawn.

The "zelfstandige werkruimte" test#

To deduct rent, utilities, or a portion of your mortgage on your home office, the space must qualify as a "zelfstandige werkruimte" — a dedicated, independent workspace. It must have:

1. Its own entrance (or a separate door that guests do not have to pass through the main living area to access).
2. Its own toilet and washing facilities (or at least exclusive use of a shared bathroom).
3. Be used exclusively for work (not a bedroom by night, workspace by day).
4. An income share (your business must earn a material portion of your income from that space — not a hobby).

Almost nobody qualifies. If you work in your living room, a shared bedroom, or a corner of your kitchen, the test fails immediately. Even a spare bedroom that you don't sleep in usually fails because it shares entry and facilities with the rest of your home.

What you CAN deduct#

Even if the room itself doesn't qualify, you can still deduct several things:

Furniture and equipment#

A desk, chair, bookshelf, or filing cabinet bought for your home office is deductible and can be depreciated if it costs over roughly €450, or expensed at once if cheaper.

Office equipment#

Monitor, keyboard, mouse, printer, scanner, headset, microphone, camera — all fully deductible if used for work.

Software and subscriptions#

Your invoicing tool, video-conference software, project management app, accounting software — all fully deductible, whether you use it at home or elsewhere.

Utilities — the business share#

If you work from home and have internet and electricity costs, you can deduct the business portion. This is typically:

• Internet: 50–70% business (the rest is streaming, browsing, personal use). Some freelancers justify 80–90% if they're online for work most of the day.
• Electricity: 10–20% of your home's total (it's a small share, and auditors rarely push back on reasonable estimates).

Document your estimate. For internet, you might write: "Unlimited home broadband €50/month, 60% business use = €30/month deductible." For electricity, a room-size calculation works: "Home office is 15% of total floor area, so 15% of electricity is business = €X/month."

Phone and mobile costs#

If you use a landline or mobile exclusively for work, it's fully deductible. If you use it for personal calls too, split it (e.g., 70% business).

What you CANNOT deduct#

• Rent or mortgage (unless the workspace qualifies as "zelfstandige werkruimte" — which it almost certainly doesn't).
• Council tax or property tax (not deductible for any part of the home).
• Home insurance (personal, not business).
• Water rates (usually personal, though a tiny share is arguably business).
• Gas heating (personal, though a proportion of the bill is arguably business use, but it's rarely worth arguing).
• The room itself (depreciation of the structure — not allowed for a home).

Workarounds#

If your home office fails the test, consider these alternatives:

Rent a co-working space#

A desk or small office at a co-working space is 100% deductible. Many zzp'ers find that a few days a week in a shared space keeps them focused and solves the deduction problem entirely. Monthly costs range from €50–€300 depending on location and amenities.

• Research co-working spaces in your area
• Compare pricing and facilities
• Consider part-time or hot-desking options
• A co-working invoice is a clean business deduction

Claim the fixed flat-rate deduction#

Some freelancers use a standard allowance approach: estimate your home office costs annually (utilities, phone, a portion of rent or mortgage) and claim a fixed amount (e.g., €100–€200/month) without detailed justification. The Belastingdienst usually accepts modest, round numbers. However, you must still be able to justify it if audited.

Furnish and equipment only#

This is the most conservative approach: deduct only the furniture, equipment, and utilities that clearly serve your work. Skip the room itself, and rest assured your claim is solid. This is probably what your accountant will recommend.

Depreciation of home office equipment#

Furniture, equipment, and improvements to your home office:

• Over €450: depreciate over the asset's useful life. A desk or chair: typically 5 years. A computer: 3–4 years. A renovation: often 20 years (building improvement) or fully expensed if it's minor.
• Under €450: expense immediately (deduct the full cost in the year you buy it).

See depreciation of business assets for the detailed rules and how to build a depreciation schedule.

Frequently asked questions#

The Dutch home office rules are frustratingly restrictive, but they're not designed to be unfair — they're designed to stop abuse. Most home-based freelancers simply deduct furniture, equipment, and a reasonable share of utilities. That's defensible, honest, and usually enough. ZZP Belasting helps you track all these costs clearly, so you know exactly what you can claim and why.
