In this 2026 guide, we explain the Dutch VAT number format, covering the following topics: how a Dutch VAT identification number and VAT tax number are structured, what each part means, and how they differ from other business identifiers in the Netherlands. We will provide a Netherlands VAT number example, learn how to perform a VAT number check in the Netherlands, and understand when and how these numbers are validated at the European level. This guide also covers common mistakes that can cause issues for international companies, especially those that wish to expand or relocate into the Netherlands.

What Is a Dutch VAT Number?

For many directors and business owners who set up a Dutch entity, VAT is not optional. Once a company is registered with the Dutch Chamber of Commerce, most companies are required to obtain a VAT identification number in the Netherlands to invoice, file VAT returns, and for compliance reasons with Dutch and European tax rules. The VAT identification number itself is issued by the Belastingdienst and follows a strict format that must be used consistently on invoices, contracts, and transactions in the European Union. Accounting services by consultancy firms such as Beyond can assist in ensuring that a company’s invoicing complies with all these regulations.

The purpose of a Dutch VAT identification number is to identify your company as VAT-registered in the Netherlands. It thus serves as the official tax identifier for VAT purposes. The number is used to charge, collect, and reclaim VAT, and to report VAT to the Dutch tax authorities. If a company formats or uses a Dutch VAT number incorrectly, the invoicing can be blocked, payments can get delayed, or it can result in compliance questions.

In the Netherlands, VAT is commonly referred to as BTW (Belasting over de Toegevoegde Waarde). For business owners, it is important that VAT is an international and European term, and that BTW is Dutch terminology.

Dutch business owners commonly receive two numbers for VAT: the VAT identification number and the VAT number. The VAT identification number is used for all your contacts with customers and suppliers, such as invoices and websites, and to do business in the European Union.Not every company receives a VAT number automatically, as it depends on the business activities, the type of transactions, and VAT liability. A VAT identification number in the Netherlands is issued to:

Dutch BVs and NVs carrying out taxable activities
Foreign-owned companies with a Dutch establishment
Directors operating a Dutch company with VAT-liable transactions
Companies that are expanding into Europe via the Netherlands

The VAT tax number is used for contact with the Tax Administration. If business owners need to call the Tax Information Line, or if they write a letter to the Tax Administration, they will need to use this number. To understand how a Dutch VAT number is composed, we will inform you about its format.

Netherlands VAT Number Format Explained

The Netherlands VAT identification number format follows a standard structure that applies to the majority of Dutch companies registered for VAT. A standard Netherlands VAT number format looks like this:

NL + 9 digits + B + 2 digits (example: NL123456789B01)

Here is the meaning of each part of the format:

NL: Country code for the Netherlands
9 digits: Unique taxpayer number
B: Indicates a VAT registration
2 digits: Suffix identify the VAT entity

The last two digits distinguish the VAT registration from other tax identifiers and may change in some situations, such as multiple VAT registrations or administrative adjustments. The most common reason for invoices to be rejected or for failed VAT checks is the use of an incorrect suffix.

VAT tax number format Netherlands is for sole proprietorships and consists of the citizen service number (BSN), followed by the letter B and two digits. For other legal structures, the RSIN number is followed by the letter B and two digits. There is no NL in front of the VAT tax number, compared to the VAT ID. A VAT tax number Netherlands example would look like this:

BSN/RSIN number + B + 2 digits (example: 112234567B01)

Keep in mind that if you are not an entrepreneur for VAT purposes, then you do not need to have a VAT ID number in the Netherlands or a VAT tax number. Consultancy firms such as Beyond Solutions can assist international business owners in validating if they need these numbers for their Dutch business.

VAT Number vs KVK Number

VAT number Netherlands is often confused with KVK by owners of foreign companies, but they serve different purposes. The KVK number (business registration) is issued once the company is incorporated and identifies the company in the Dutch business register. This number is used for legal and administrative purposes. The VAT number (tax identifier) is issued separately by tax authorities and used only for VAT reporting and invoicing. This number is required for European VAT validation.

Using a KVK number instead of a VAT number on invoices is a frequent error among international business owners and can result in non-compliant invoices or rejected VAT deductions. Therefore, it is important to understand both and to know how to check a VAT number in the Netherlands.

How to Check a VAT Number in the Netherlands

There are official verification tools to perform a Netherlands VAT number check before issuing invoices. Businesses usually verify VAT numbers through European VAT validation systems and Dutch tax authority databases. A Netherlands VAT number check confirms whether the VAT number is valid, if the number belongs to an active business, and if the registration can be used for European transactions.

VAT validity must be checked before invoicing to European clients, when applying reverse-charge VAT rules, and during audits or compliance reviews. When a business fails to verify VAT numbers, this can expose the company to compliance and financial risks.

Common VAT Number Formatting Mistakes

Foreign companies often commit formatting mistakes when it comes to the Dutch VAT number, causing invoicing and compliance issues. The following are common mistakes:

Missing the “NL” country prefix
Using an incorrect digit count
Entering a KVK number instead of the VAT number
Confusing VAT tax number with VAT ID, and vice versa
Applying outdated or inactive VAT numbers

It is crucial to make sure that the invoice is formatted with the correct Dutch VAT number, in order to ensure a smooth operation. If you are unsure about this, Beyond Consultancy can assist you to double check information and to make sure you comply with the Dutch tax system.

Do You Need a VAT Number for Invoicing?

It depends on your transaction type and business setup if you need a VAT number in the Netherlands. For domestic invoicing in the Netherlands, most Dutch companies require a VAT number to supply taxable goods or services. A valid VAT identification number Netherlands is also required for supplies within the European Union and for reverse-charge VAT arrangements.

Non-EU clients do not necessarily require a VAT number for invoicing. In this situation, VAT requirements depend on service type, place of supply rules, and local and European VAT regulations. Companies that expand into the Netherlands often require VAT registration, especially when operating within the EU.
