The question nobody answers
Most CV advice assumes you are applying at home. A Pole looking for work in Poland has plenty to read. A Pole applying to the Netherlands is doing something different, and almost nobody writes about it.
You do not need a work permit. Poland is in the EU, and so is the Netherlands. What you need is to avoid four specific frictions that have nothing to do with whether you are good at the job.
1. The BSN trap, and it costs 52%
This is the one that catches people, and it is the reason this article exists.
To be paid normally in the Netherlands you need a BSN (burgerservicenummer), the Dutch citizen service number. You get one by registering with the gemeente (municipality) where you live.
If your employer does not have your BSN, name and address before your first working day, they are legally required to apply the anoniementarief — the anonymous rate — and withhold 52% of your wages in payroll tax. This is article 26b of the Wet op de loonbelasting 1964. It is not a penalty and it is not discretionary; your employer has no choice.
Now the part almost nobody tells you:
- The deadline is before the work starts, not before the first payslip.
- Your employer may not go back and correct it. Once the anonymous rate has been correctly applied to a period, earlier payroll filings stay as they are. Corrections are only allowed where the rate was applied by administrative mistake.
- You get the money back through your own annual income tax return (aangifte inkomstenbelasting), not through your employer. That can mean waiting until the following year.
So the practical rule is simple: start the registration before you start the job, not after. If your start date is close, tell your employer and ask what they need from you and when.
The catch-22 to plan around: registering with the gemeente generally requires a Dutch address, and a Dutch address often requires a job, and being paid properly requires the registration. This is a real ordering problem and it is worth solving deliberately rather than discovering it in week one. Ask the employer whether they help with registration — many that recruit abroad do, and the ones that do not will at least tell you which gemeente and what to bring.

2. Which language to write in
There is no single answer, and the honest version is a rule of thumb:
- International, tech, logistics, engineering, and anything at a multinational: English is usually fine and often expected.
- Roles serving Dutch customers, public sector, healthcare, education, and most SMEs: Dutch, or at minimum a Dutch cover letter with an English CV and a line about your Dutch level.
If the vacancy is written in Dutch, answer in Dutch. If it is written in English, English is safe. That sounds obvious and it is the single best signal available to you.
State your Dutch level honestly using CEFR (A2, B1, B2). Overstating it is discovered in the first phone call and costs you the benefit of the doubt on everything else.
3. What to remove from your Polish CV
Two things that are normal in Poland and read badly in the Netherlands:
The RODO/GDPR consent clause. A Polish CV usually carries a data-processing consent line at the bottom. It belongs on a Polish CV. On a Dutch one it is noise at best, and at worst it signals a copied template.
The photo, date of birth and marital status. Dutch practice leans away from all three. Some employers still see photos and nobody will reject you for one, but leaving them off is the safer default and removes an unconscious-bias objection before it exists.
Two pages is acceptable in the Netherlands. You do not need to compress a real career onto one.
4. The reference gap, in reverse
Applying to Germany, a Pole gets asked for an Arbeitszeugnis — an evaluative reference Poland does not issue. The Netherlands has the mirror-image problem and it is gentler, but worth knowing.
Polish świadectwo pracy is a purely factual employment certificate: who employed you, in what role, for how long. Polish law provides for no assessment, so there is nothing evaluative in it.
Dutch employers typically expect named referees you can be contacted about, or sometimes a getuigschrift. If you offer a świadectwo pracy as a "reference", it will read as strangely thin — not because it is, but because it is answering a different question.
What to do: list two referees with role, relationship and contact details, and say plainly that Polish employers issue factual certificates rather than written references. One sentence removes the confusion entirely.
5. Qualification recognition: start it early or not at all
For most jobs you need nothing. Your degree is your degree.
For regulated professions it is different, and the timeline is the problem rather than the difficulty:
- Healthcare (nurses, doctors, physiotherapists, pharmacists): registration in the BIG-register is mandatory before you may practise or use the title. Start this before you apply, not after you are offered something.
- Teaching, law, and several trades: check the specific regulator for the profession.
- Everything else: a credential evaluation from Nuffic / IDW is often requested to express a Polish qualification in Dutch terms. It is not usually mandatory, but it makes a CV easier to read for someone who has never seen a Polish diploma.
Processing times and fees vary and change. Check with the issuing body — BIG-register, Nuffic, or the relevant regulator — rather than trusting a number in an article, including this one.
6. The order to do things in
Ordered so the slow things start first, which is the only ordering that matters:
1. Qualification recognition, if your profession is regulated. Longest lead time by far.
2. Credential evaluation (Nuffic/IDW), if you want it, in parallel.
3. The job.
4. Address, then gemeente registration, then BSN — before your first working day. See section 1. This is the one with a hard deadline and a 52% price.
5. DigiD, once you have a BSN. You will need it for almost every government service afterwards.
6. Health insurance. Mandatory in the Netherlands, with a deadline after registration.
What this does not change
None of this makes you a better candidate for a job you are not qualified for. What it removes is the friction that has nothing to do with your competence — the recognition started three months too late, the reference nobody told you needed explaining, and a payroll rate that takes half your first payslip because a number was missing on day one.
Those are the things that cost people offers they had already earned.
