Freelancing as a student: tax, study finance and KVK

Freelancing as a student is common—and entirely legal. But it changes everything about your student status, your grants, and your tax obligations in ways that can surprise you. This guide walks you through the practical and financial implications of going freelance while you're still in school.

Can you freelance while studying?#

Yes. There is no legal bar to registering at the KVK (Chamber of Commerce) and setting up as a freelancer while a student. Employers and clients don't care whether you're enrolled; they care whether you can deliver the work. The complication isn't legality—it's money and administration.

The KVK registration: it's mandatory#

If you intend to freelance more than incidentally, you need to register at the KVK. This is not optional—it is a legal requirement for any self-employed activity above pocket-money scale. The moment you invoice a client for work, you're running a business (however small), and the Belastingdienst expects you to be registered.

The good news: the KVK registration costs about €80 and takes a couple of weeks. You can read the full KVK registration guide for the step-by-step process.

The complicated part: telling DUO (the student finance authority) that you've registered.

How freelancing affects your study finance (DUO)#

This is where it gets serious. If you receive any form of study finance—studeren.nl, a specific college grant, or welfare support—your freelance income may reduce or eliminate it. Here's why:

DUO and the municipality assess your household income and assets. If you earn freelance income, it counts toward your toetsingsinkomen (assessment income). In practice:

• Below ~€15,000–€17,000/year: Often no immediate impact. Many students freelance at small scale and stay under the threshold.
• €15,000–€25,000/year: Your grant may be reduced or means-tested away. DUO recalculates based on your expected annual profit.
• Above €25,000/year: You are likely no longer eligible for most study finance.

The assessment window#

DUO typically assesses income for the study year based on the previous calendar year. So if you start freelancing in September, your 2024 income matters most for your 2025 study grant. Timing and profit forecasting become critical.

If you expect to earn significantly, speak to your DUO contact or a financial advisor before registering at the KVK. Some students strategically time their registration or adjust their invoicing to align with the calendar year in which they want to minimize their reported income.

Zorgtoeslag (health insurance allowance)#

Separately, if you receive zorgtoeslag (subsidy for health insurance), your freelance income is also relevant. The zorgtoeslag is income-tested and recalculated annually. Starting a freelance business can reduce or eliminate your zorgtoeslag.

The urencriterium problem: the 1,225-hour rule#

Here's where freelancing and studying collide head-on. To claim many of the tax deductions available to freelancers—especially the zelfstandigenaftrek (self-employed deduction)—you must meet the urencriterium: working at least 1,225 hours per year on your freelance business.

1,225 hours per year is roughly 24 hours per week, 50 weeks a year. Full-time.

As a full-time student taking 40–60 hours of classes and study per week, adding a genuine 24 hours of billable freelance work is nearly impossible. Here's the reality check:

• Part-time freelance work (10–15 hours/week): You're nowhere near 1,225 hours and cannot claim the zelfstandigenaftrek or startersaftrek.
• Seriously juggling study and freelance (20+ hours/week): You might scrape toward 1,225 hours, but your study will likely suffer, and the hours are hard to defend on paper.

The Belastingdienst is strict about the urencriterium. They expect a time log (uren­registratie) showing when you worked. If your recorded hours don't make sense for the type of work you claim, you'll lose the deduction.

The practical implication#

Most students who freelance do not meet the urencriterium, which means:

1. You cannot claim the zelfstandigenaftrek (saving you €600–€1,500/year in tax).
2. You cannot claim the startersaftrek (another €400–€650/year).
3. You lose deductions on your profit calculation, so more of your freelance income is taxable.

If you freelance part-time as a student, you're essentially paying higher tax on your lower income. It's unfair, but it's the rule.

Small business scheme (KOR): a possible escape hatch#

If your annual freelance income is under €20,000, you can opt into the KOR (kleineondernemersregeling), the small business scheme. The KOR exempts you from filing VAT returns and allows you to invoice without VAT—but only if your turnover stays below the threshold.

The KOR advantage for students:

• No urencriterium required. The KOR doesn't care whether you work 1,225 hours or 100 hours.
• Simpler tax filing. No quarterly VAT returns. Your annual income tax return is your main obligation.
• Smaller tax bill. You avoid some of the additional tax complexity.

The KOR downside:

• No VAT reclaim. You cannot reclaim VAT on business expenses (software, equipment, travel). This can add 15–20% to your costs.
• Invoice differently. You invoice without VAT and note the exemption, which may confuse B2B clients who expect VAT-registered invoices.

For a student earning under €15,000 in profit, the KOR is often sensible. For higher incomes, the inability to reclaim VAT becomes expensive. Read the full KOR guide to decide.

Handling your tax filing#

Your income tax return (aangifte inkomstenbelasting) combines your study status with your freelance profit:

1. Box 1 (inkomstenbelasting): You declare your freelance profit, losses, and deductions.
2. Study deductions: If you paid course fees or relevant education costs, some may be deductible as business expenses (especially if the course directly relates to your freelance work).
3. Allowances and credits: Depending on your profit and household situation, you may still be eligible for the arbeidskorting or other credits, even as a student.

Common scenarios#

Scenario 1: Freelance design work, ~€12,000/year, 500 hours. You're below the KOR threshold and cannot meet the urencriterium. Opt for the KOR, invoice without VAT, file a simple annual return, and forget about quarterly filings. You cannot reclaim VAT, but your volume is small enough that it doesn't hurt much. Study finance remains mostly intact (depending on your household income).

Scenario 2: Freelance tutoring or coaching, €8,000/year, 200 hours. Below KOR, way below urencriterium. You don't register for VAT. You file your annual return with your profit. You cannot claim zelfstandigenaftrek, but your profit is small anyway. Check whether this income triggers zorgtoeslag loss.

Scenario 3: Freelance contract work, €35,000/year, 1,500 hours. You likely exceed the KOR threshold. You must register for VAT and file quarterly returns. You can argue that you meet the urencriterium (1,500 hours is solid), so you can claim deductions. But your DUO study finance is almost certainly affected. You're earning more than many full-time employees. Your status becomes "student who is also self-employed" rather than a student with a side gig.

Key takeaways#

• Register at the KVK if you freelance beyond pocket money.
• Tell DUO immediately. Hiding freelance income is illegal and discovered.
• Check your grants and allowances carefully; they may be clawed back.
• The urencriterium is hard. Document hours if you attempt it; otherwise, forget the deduction.
• The KOR is often a good fit for student freelancers earning under €20,000.

Freelancing as a student is viable, but it requires honest planning. The tax rules don't discriminate between students and others; you pay tax like any self-employed person. The real challenge is managing your study time while meeting financial obligations to DUO and the Belastingdienst.

If you're unsure about your specific grants or tax position, a free consultation with a belastingadviseur (tax advisor) or your DUO contact is worth the time. They can forecast your actual tax bill and help you decide whether the timing is right. When you're ready to set up, ZZP Belasting can help you track your income, hours, and deductions so that your annual return is straightforward.
