Netherlands Tax ID Number (TIN) Guide

In the Netherlands, Tax Identification Numbers (TINs) are essential for individuals and entities to comply with tax regulations. The correct TIN ensures accurate tax reporting and facilitates interactions with Dutch tax authorities. All information presented here is verified from official sources, including the Dutch Tax and Customs Administration (Belastingdienst).​ 

Tax Identification Number Types 

The Netherlands utilizes two primary types of TINs:​ 

1. Burgerservicenummer (BSN): This Citizen Service Number is assigned to individuals.​ 

2. Rechtspersonen en Samenwerkingsverbanden Informatienummer (RSIN): This Legal Entities and Partnerships Identification Number is assigned to legal entities and partnerships.​ 

The BSN is applicable to all residents and is used for various administrative purposes, including taxation. The RSIN is assigned to legal entities and partnerships for tax identification.  

TIN Format and Structure 

Burgerservicenummer (BSN): 

• Format: A unique 9-digit number.​ 

• Structure: The BSN does not have a segmented structure; it is a straightforward 9-digit identifier.  

Rechtspersonen en Samenwerkingsverbanden Informatienummer (RSIN): 

• Format: A unique 9-digit number.​ 

• Structure: Similar to the BSN, the RSIN is a 9-digit number without specific segmentation.  

Issuing Authority and Registration Process 

Burgerservicenummer (BSN): 

• Issuing Authority: The Dutch government assigns the BSN through the Municipal Personal Records Database (Basisregistratie Personen, BRP).​ 

• Registration Process: 

1. Eligibility: All individuals residing in the Netherlands.​ 

2. Required Documents: Valid identification (e.g., passport) and proof of address.​ 

3. Application: Upon registering with the municipality (gemeente) where they reside, individuals are automatically assigned a BSN.​ 

4. Fees: There are no fees for obtaining a BSN.  

Rechtspersonen en Samenwerkingsverbanden Informatienummer (RSIN):

• Registration Process: 

1. Eligibility: Legal entities and partnerships operating in the Netherlands.​ 

2. Required Documents: Company formation documents, identification of directors/partners, and proof of business address.​ 

3. Application: Entities register with the Dutch Business Register (Handelsregister) at the Chamber of Commerce (Kamer van Koophandel, KvK). Upon registration, the KvK assigns a KvK number and informs the Belastingdienst, which then issues the RSIN.​ 

4. Fees: Registration fees are determined by the KvK.
