Are you an entrepreneur for tax? The Belastingdienst test

The difference between being an ondernemer (entrepreneur) and earning income from "other activities" might seem like tax jargon, but it's one of the most important distinctions you'll make in Dutch tax law. Get it wrong, and you'll lose access to valuable deductions that can save you thousands of euros each year. Get it right, and your tax status unlocks the full suite of entrepreneur benefits.

The Dutch tax office uses five specific criteria to test whether you truly qualify as an ondernemer. Pass the test, and you're eligible for entrepreneur deductions like the zelfstandigenaftrek. Fail it, and you're treated as earning income from something else—and those deductions disappear.

What does "ondernemer" mean?#

In the Netherlands, the term ondernemer has a precise legal meaning in the eyes of the Belastingdienst. It's not enough to call yourself self-employed or freelance. The tax office will verify that you meet its definition, which is based on five core criteria:

The other two criteria are:

• 4. Continuity: Your business is intended to last (not a one-off project)
• 5. Hours: You work at least 1,225 hours per year (or work towards meeting this)

The five criteria explained#

1. Independence (zelfstandigheid)#

You must work independently, not under the direction or control of someone else. The key test: who decides how and when you do the work?

You are independent if:

• You decide your own working hours and methods
• You choose which clients to take on
• You can refuse a job without penalty
• You set your own fees (within market rates)
• You make your own business decisions

You may NOT be independent if:

• A client dictates your exact hours, location, or methods
• You work under someone else's supervision or performance management
• You cannot refuse work without serious consequences
• Your fee is non-negotiable and set by the client
• You're integrated into the client's organisation (using their tools, reporting to their managers, bound by their workplace rules)

2. Economic risk (ondernemingsrisico)#

You must stand to lose money if things go wrong. In other words, there's genuine financial risk in your business.

You have economic risk if:

• You invoice after completing work (not paid upfront)
• A client can refuse to pay and you have to absorb the loss
• You invest in tools, training, or materials before knowing if you'll be paid
• You bear the cost if a project runs over or has quality issues
• You keep unsold inventory at your own risk

You do NOT have real risk if:

• You're paid in full before or during work (no possibility of non-payment)
• The client covers all costs and materials
• You're guaranteed payment regardless of the outcome
• Someone else (a parent company, guarantor) covers your financial exposure

3. Multiple clients (meerdere opdrachtgevers)#

The Belastingdienst generally expects you to work for at least two different clients. This is one of the clearest signals that you're running a true business, not just taking one job under another name.

This criterion is met if:

• You have (or actively seek) work from multiple, independent clients
• You invoice different clients separately
• Each client relationship is negotiated independently

This criterion is NOT met if:

• You work exclusively for one client (especially for long periods)
• You have one main client and only occasional work from others
• You have no realistic plan to diversify your client base

4. Continuity (voortzetningsoogmerk)#

Your business must be intended to continue, not just a one-off project or temporary gig.

Continuity is present if:

• You register at the KVK (Chamber of Commerce)
• You offer your services on an ongoing basis
• You plan to stay in business for several years
• You invest in tools, skills, or infrastructure for the long term
• You have multiple projects or clients over time, not just one

Continuity may be lacking if:

• You only take on a single, time-limited project
• You explicitly tell clients this is temporary work
• You have no infrastructure or business planning beyond the next job
• You're doing this only until you find a regular job

5. Hours (urencriterium)#

Finally, the Belastingdienst expects you to work at least 1,225 hours per year as an entrepreneur.

• Count direct billable hours to clients (consulting, design, coding, etc.)
• Include indirect hours (admin, marketing, training, business development)
• Measure hours worked, not hours billed (unpaid admin counts)
• For year one: show progress toward 1,225 hours; the rule is enforced strictly from year two onwards
• Keep a time log (urenregistratie) as proof — auditors expect this

At least 1,225 hours a year works out to roughly 24 hours per week, 52 weeks per year (or 50 hours per week over a 25-week engagement). If you can't reach this consistently, the Belastingdienst will question your ondernemer status.

Why this matters: the deduction consequences#

The stakes are high because ondernemer status unlocks specific deductions you cannot claim otherwise:

• Zelfstandigenaftrek: A deduction of up to €3,750 per year (2025 figure; phasing down to ~€900 by 2027)
• Startersaftrek: An extra €2,123 deduction in your first three of five years (if you meet the urencriterium)
• MKB-winstvrijstelling: A 12.7% automatic deduction on your profit
• Vermogensrendementsheffing (box 3) exemption: Money in your business account is not taxed as savings

If you fail the ondernemer test, you lose all of these. You're treated as earning "resultaat uit overige werkzaamheden" (income from other activities), and you pay tax on the full amount with no entrepreneur benefits.

Over a €40,000 profit, the difference can easily be €5,000–€8,000 in extra tax per year.

When might you fail the test?#

Common scenarios where the Belastingdienst might deny ondernemer status:

Full-time single-client work: You work 40 hours/week for one client for two years straight, in their office, using their systems, reporting to their manager. This looks like a job, not a business. Risk: High.

Dependent contractor with a large company: You're bound by their contract, they set your rate, they manage your schedule, and they are your only income source. Risk: High.

Hobby income: You sell crafts or advice sporadically, work only 10 hours a year, and have no growth plan. Risk: High.

Short-term project: You take on a three-month contract, have no other clients, and tell everyone it's temporary. Risk: High.

Moonlighting with no plan: You freelance 4 hours a month on top of your main job, have one client, and have never looked for more work. Risk: Medium to High.

How to strengthen your ondernemer status#

If you're borderline or worried about a challenge, here's how to bulletproof your position:

1. Diversify your clients

• Never rely on a single client for more than 50% of your income
• Actively pitch new business; keep records of your pitches and rejections
• If you must work for one client, make sure it's time-limited (6–12 months, not ongoing)

2. Keep meticulous time records

• Log your hours weekly (direct work + indirect/admin hours)
• Use software or a simple spreadsheet
• Auditors will ask for this; it's your primary defense

3. Establish independence

• Set your own rates (don't accept non-negotiable fees from a powerful client)
• Negotiate your schedule and deliverables
• Use independent tools and work your own way

4. Document your risk

• Invoice after delivering work (or at milestones), not upfront
• Keep invoices unpaid until payment is made (or long enough to prove risk)
• Invest your own money in tools, training, or materials

5. Build infrastructure

• Register at the KVK
• Open a business bank account
• Get business insurance
• Have a website, portfolio, or marketing presence
• File your annual tax return as an entrepreneur

6. Plan for the long term

• Set aside money for tax, pension, and buffers
• Invest in improving your skills
• Build processes and systems, not just project-to-project work
• Plan year two and beyond, not just the next contract
