Part-Time Student Jobs in the Netherlands: BSN, Payroll Tax, and Holiday Pay

Getting your BSN

The BSN, burgerservicenummer, is the citizen service number every employer, bank, and health insurer in the Netherlands asks for. You get one by registering your address at the local gemeente, the municipality, which issues the number as part of that registration. Bring your passport or ID, proof of address such as a rental contract, and your enrollment confirmation to the appointment, then give the BSN to your employer and use it to open a Dutch bank account. Keep the confirmation letter from the gemeente somewhere safe, since some banks and insurers ask to see it alongside your number during their own verification steps.

Book your gemeente appointment as soon as you have a rental address, since popular cities often have appointment slots booked out for weeks around the start of each semester, delaying both your BSN and your first correctly taxed payslip.

Why the BSN matters for tax

Without a BSN on file, an employer withholds tax at a higher emergency rate rather than your normal rate, since the payroll system will not apply your personal tax credits without it. According to EURAXESS guidance on Dutch payslips , register your BSN with your employer as soon as you receive it, so the correct rate applies from your first pay period instead of getting refunded later through a tax return.

Reading your payroll tax (loonheffing)

Loonheffing is the combined deduction covering income tax and social security contributions, shown as one line on your payslip rather than split out. Apply your general tax credit, loonheffingskorting, at only one employer at a time, so if you hold two part-time jobs, put it toward the one paying more to reduce total withholding.

Opening a Dutch bank account

Most employers pay wages only into a Dutch bank account, so open one soon after you get your BSN, since banks generally ask for it during account setup along with your passport and proof of address. Some banks offer a basic account aimed at students with lower or no monthly fees, worth comparing before picking the first branch near your accommodation.

Holiday allowance (vakantiegeld)

Dutch law requires employers to add at least 8 percent of your gross salary as holiday allowance, on top of normal pay, whether you work full or part time, according to Business.gov.nl . Most employers pay this out as a lump sum in May, though some spread it monthly instead, so check your contract for which method your employer uses. Vakantiegeld shows up as its own line on your payslip rather than folded into your regular gross pay, making it easy to spot once it arrives.

Working more than one job

Nothing in Dutch law caps you to one employer, so many students combine a campus job with weekend shifts elsewhere. Track your total hours against your visa or permit condition if you fall under the non-EU/EEA category, since the hour cap applies to your combined work across every employer rather than to each job separately.

Pension contributions

Pension-eligible salary appears on your payslip as a separate figure from gross pay, since not every part-time or short contract falls under a mandatory pension scheme. Whether pension contributions apply to your specific role depends on your employer's collective labor agreement, the CAO, and your age, so check your contract or ask HR directly rather than assuming either way.

Non-EU/EEA students: work permit and hour limits

Students from outside the EU/EEA generally need a separate work permit tied to their residence permit, and their employer typically applies for it. Working hours for non-EU/EEA students are usually capped during term time, with more flexibility during the summer months, so confirm your specific limit with your university's international office or the IND before accepting shifts, since limits vary by permit type and change from time to time. Some universities run a short workshop on this during orientation week specifically for non-EU/EEA students, worth attending before you sign a work contract.

Health insurance stays separate

A part-time job in the Netherlands does not automatically enroll you in Dutch health insurance the way payroll tax gets deducted automatically. EU students usually stay covered through their home country's EHIC or S1 arrangement, while non-EU students typically need to arrange Dutch health insurance separately when they register, so confirm your specific situation with your university's international office rather than assuming your job covers it.

Quick checklist before your first shift

• Register your address at the gemeente and receive your BSN

• Give your BSN to your employer before your first payslip

• Confirm which employer applies your loonheffingskorting if you hold two jobs

• Check your contract for how vakantiegeld gets paid out

• Non-EU/EEA students: confirm your permit and hour limit before agreeing to shifts
