What Is a TIN Number in the Netherlands?
In the Netherlands, the Tax Identification Number (TIN) for individuals is the BSN – Burger Service Nummer.
This is the unique personal identifier used across all government, tax, and administrative systems. Every Dutch citizen and every legally registered expat receives one.
You need a BSN for income tax, employment, healthcare registration, social benefits, banking, insurance, and most formal interactions with Dutch institutions.
Quick Facts About the Dutch TIN (BSN)
- Format: 9-digit number, usually following the 11-check algorithm.
- Who assigns it: The municipality (gemeente) upon registration in the BRP (personal records database).
- Where it’s stored: ID documents, Belastingdienst letters, MijnOverheid, employer payroll systems.
When it’s required: Employment, tax filings, insurance, healthcare, studying, opening a bank account.
Where to Find Your Dutch TIN (BSN)
Most people receive their BSN during their first registration appointment in the Netherlands. After that, you can find it in several secure locations – both physical and digital.
On Your ID Documents
You can locate your BSN on:
- Dutch passport – typically on page 2, near the machine-readable zone.
- Dutch ID card – printed on the back side.
- Residence permit (certain types) – some permits include the BSN, but this is not guaranteed for all categories.
In Official Letters
Your BSN is also present in official documents such as:
- letters from Belastingdienst (Dutch tax authority);
- the municipality registration confirmation (BRP document) received after your first appointment;
- health insurance correspondence, depending on the provider.
In Your Digital Profiles
If you use Dutch digital services, your BSN appears in:
- your DigiD account (digital identity system);
- the MijnOverheid portal (your central online government dashboard);
- your employer’s payroll or HR portal (on pay slips and tax statements such as the jaaropgave).
- OECD website (global forum analyzing economic trends and coordinating policy to improve worldwide well-being.)
TIN Number (BSN) vs VAT Number vs RSIN vs KvK: What’s the Difference?
This is one of the most confusing areas for newcomers. Each number serves a different purpose and applies to different entities.
For Individuals
BSN (Burger Service Nummer) – your personal identification number and taxpayer ID (TIN).
Used for employment, tax filings, healthcare, education, benefits, and identity verification.
For Companies
- BTW-nummer (VAT number) – used for invoicing, EU trade, and VAT reporting.
- RSIN – assigned to certain legal entities such as foundations, associations, and partnerships.
- KvK number – your registration number with the Kamer van Koophandel; required for nearly all business activity.
Comparison Table: BSN vs KvK vs RSIN vs BTW (VAT)
| Identifier | Who Receives It | Format | Purpose / Use Cases |
| BSN (TIN) | Individuals (residents & registered expats) | 9 digits | Tax filing, employment, healthcare registration, banking, education, government services |
| KvK Number | All registered businesses (BV, NV, sole proprietors, partnerships, etc.) | Numeric (8 digits) | Company registration, legal identity, required for contracts, invoices, opening business bank accounts |
| RSIN | Legal entities (foundations, associations, partnerships, some companies) | Numeric | Corporate tax identification, administrative records, used by Belastingdienst |
| BTW Number (VAT) | VAT-registered businesses | “NL” + 9 digits + B + 2 digits (e.g., NL123456789B01) | Invoicing, EU trade, VAT reporting, international transactions |

How to Get a TIN (BSN) Number in the Netherlands as an Expat
Expats receive their Dutch TIN when they register in the BRP (Basisregistratie Personen) at their local municipality.
The number assigned during this process is the BSN, which functions as the official Dutch TIN.
Step-by-Step Guide
- Schedule an appointment at your municipality (gemeente). Appointments are required in most cities, especially larger ones.
- Bring the required documents:
- Passport
- Rental contract or other proof of address
- Birth certificate (in some municipalities; may require an apostille)
- Register in the BRP. This is the national population registry used by governmental bodies.
- Receive your BSN (TIN).
- In many municipalities, the BSN is issued during the appointment.
- In some cases, it is sent by post shortly after.
Processing Time
- Typical timeframe: same day or within 1–5 business days.
- For short-stay or temporary workers, the issuance may take slightly longer depending on the registration category.
What If You Don’t Have a Fixed Address Yet?
If you have not secured housing, several options remain available:
- Register at a temporary address, such as staying with a friend or relative (with their written permission).
- Employer-assisted registration: some companies provide temporary accommodation or facilitate registration for new hires.
- Knowledge migrants may qualify for expedited processes depending on municipality capacity.
Lost Your TIN/BSN? Here’s What to Do
There is no “replacement number,” but you can retrieve your existing BSN through several official channels.
If You Still Live in the Netherlands
- Visit your local municipality office to request documentation containing your BSN.
- Log into your DigiD (DigiD) account – your BSN is visible in linked services.
- Check your MijnOverheid profile – the central portal for digital government communication.
- Request a new copy of official letters from Belastingdienst if needed.
If You Already Left the Country
If you previously lived in the Netherlands but no longer reside there:
- Register or update your details in the RNI (Non-Residents Register).
- Contact the Belastingdienst International Office with your passport and former Dutch address.
- They can confirm and provide your BSN for tax or administrative needs.
Dutch TIN Number for Non-Residents (RNI Registration)
Individuals who do not permanently live in the Netherlands but interact with Dutch institutions can obtain a TIN through RNI (Register Niet-Ingezetenen). This process issues the same BSN number, but with a non-resident status.
Who Qualifies?
You can register in the RNI if you:
- work in the Netherlands but live abroad (cross-border workers);
- come for seasonal or short-term employment;
- previously lived in the Netherlands and now reside abroad but still need a BSN for tax or administrative purposes;
- require a BSN to interact with employers, banks, tax authorities, or government services.
What You Get
RNI registration provides:
- a non-resident BSN – identical to a resident BSN but issued under non-resident status;
- limited access to digital government services, but fully valid for:
- employment;
- receiving salary;
- filing taxes;
- communicating with Dutch government and financial institutions.
How the Dutch TIN Is Used in Taxes (Belastingdienst Overview)

Dutch TIN Validation: How Institutions Verify It
BSN validation is mandatory for financial and governmental institutions. This is a strong SEO topic competitors often skip.
Who Needs to Validate a BSN/TIN
Validation is performed by:
- banks;
- financial institutions performing AML/KYC checks;
- employers;
- insurance providers;
- municipalities and government bodies.
How BSN Validation Works
Institutions verify a BSN using several steps:
- Format check: verifying the 9-digit structure and checksum;
- BRP cross-check: matching the number with the population registry;
- Tax authority data matching: confirming identity and status with tax systems.
Individuals cannot validate someone else’s BSN – only authorized institutions have access to validation systems.
TIN for Business & Corporate Entities in the Netherlands
Businesses do not receive a BSN, but they do use other identifiers. Many articles mix these concepts, so this section provides a full breakdown.
Corporate Identifiers
Legal entities may have several identifiers, each serving a different purpose:
- RSIN – assigned to foundations, associations, and partnerships;
- VAT (BTW) number – used for VAT reporting, invoicing, and EU transactions;
- KvK registration number – the official number issued by the Chamber of Commerce, required for most business activities.
When Businesses Need TIN-Like Identifiers
Companies use these identifiers for:
- filing corporate taxes;
- issuing invoices domestically and across the EU (RSIN/Btw);
- participating in international trade;een
- cross-border compliance reporting (OSS, Intrastat, etc.).
Common Problems & How to Solve Them
A structured troubleshooting section performs well in AI search because it maps directly to problem-based queries.
1. You Cannot Receive a BSN Because of Missing Documents
If documents are incomplete:
- Check your municipality’s list of accepted documents (requirements differ).
- Provide alternative proof of address (official letter, employer statement, residence confirmation).
- If your birth certificate is missing or not legalized, you can still register temporarily and deliver the document later, depending on the municipality.
- Request an extraction or legalized copy from your home country.
2. Your Appointment at the Gemeente Is Delayed
- Look for earlier slots in nearby municipalities; regulations allow you to register outside your city in many cases.
- Check for drop-in hours (smaller towns sometimes allow walk-ins).
- Ask your employer for assistance – some municipalities provide priority slots for knowledge migrants or corporate partnerships.
3. You Need a TIN Urgently for Employment
If you must start work immediately:
- You can still begin employment while waiting for your BSN; employers can temporarily use a placeholder in payroll.
- Make sure the BSN is submitted as soon as it is issued to avoid incorrect tax withholding (the “anonymous rate”).
4. Your Employer Cannot Validate Your TIN
- Confirm that you provided the exact 9-digit number without formatting changes.
- Ensure your BRP or RNI registration is finalized – BSNs may take up to a few days to propagate across systems.
- Employers must validate through official tax or payroll systems; individuals cannot validate their own BSN.
5. You Had a BSN Previously but Don’t Remember It
If you lived in the Netherlands before:
- Check your old tax letters or employment documents.
- Log into MijnOverheid or DigiD if you still have access.
- If you left the Netherlands, contact the Belastingdienst International Office or register in the RNI to retrieve your BSN.
