SBI-code 2025: What’s changing in September and what does that mean for your business?

As an entrepreneur, you already have a lot on your plate. You need to find clients, deliver your services, and keep your administration in order. One part you might not think about often is your SBI code. Yet, this code can have a bigger impact on your business than you might expect.

In September 2025, the Dutch Chamber of Commerce (KVK) will implement a major change: all existing SBI codes will be automatically updated between September 5 and 7, 2025. The goal is to ensure that the classification reflects the modern economy. But what does this mean for you? And why is it so important to check your code?

What Is an SBI Code?

SBI stands for Standard Business Classification. It’s a system used by the Central Bureau of Statistics (CBS) to categorize companies based on their economic activities.

When you register your business with the KVK, you’re assigned at least one code corresponding to your main activity. If you perform multiple types of work, you may have additional codes — for example, a consultant who also provides training.

The codes are numerical and become more specific with each digit. The first digits indicate a broad sector, while the last digits describe your exact activity.

Why Is the SBI Code Important?

You might rarely use your SBI code yourself, but it plays a major role in the background. Many institutions rely on these codes — often without you realizing it.

Some key examples include:

• Insurance – Insurers use your SBI code to determine premiums and coverage terms. If the code doesn’t match your actual work, a claim might be rejected.

• Banks and lenders – Business account or loan applications include an SBI check. An incorrect code can cause delays or even denials.

• Subsidies and grants – Government bodies and funds use the codes to decide eligibility for subsidies or support programs.

• Tax Authority – Certain VAT exemptions or obligations are tied to the SBI code. An incorrect classification can lead to retroactive tax assessments.

• Pension funds – Some industries require mandatory participation; your code determines if this applies to you.

• Municipal regulations – Local rules, zoning, or environmental policies may be checked using SBI codes.

• Labor law – If you employ staff, your SBI code may determine which collective labor agreement (CAO) applies.

In short, having the wrong code can cause a lot of trouble.

What Will Change in September 2025?

The SBI system is updated every 15 years, and the next update is now due. The economy has evolved — new professions have emerged, and older classifications no longer fit.

The main changes include:

• New codes – For rapidly growing sectors such as digital services.

• Reclassification – Some existing codes will be merged or revised to better match real-world activities.

• Extra digit – Four-digit codes will receive a zero to make the system more consistent.

• Automatic update – The KVK will apply the changes automatically between September 5–7.

You don’t need to take action, but it’s essential to check afterward that your new classification matches what you actually do.

What Are the Risks of an Incorrect SBI Code?

A wrong classification can have several negative effects. For instance:

• You might think you’re VAT-exempt but later discover you owe VAT, resulting in tax penalties.

• You could miss out on subsidies or funding because your business appears to fall outside the eligible category.

• You may encounter problems with your insurer or pension fund.

The issue often surfaces only when you apply for something or encounter a dispute — by then, it’s too late to fix easily.

How to Check Your SBI Code

Fortunately, verifying your code is simple and can save you a lot of stress.

Step-by-step guide:

1. Visit Mijn KVK and log in with DigiD or eHerkenning.

2. Review your business activity description and the linked SBI code(s).

3. Check whether it still reflects your actual work. Have your services changed? Has your main activity shifted?

4. If something is wrong, submit an update request online. The KVK will review it before making any changes.

What to Keep in Mind When Updating

• Be specific: Clearly describe what you do. A vague label like “creative services” could result in misclassification.

• Check secondary activities: If you offer additional services, ensure these are registered too.

• Consider tax implications: In sectors like healthcare or IT, the exact wording can determine VAT exemptions or tax obligations.

A well-chosen SBI code can not only prevent issues but also unlock opportunities — giving you access to programs and benefits you might otherwise miss.

Real-World Examples

Many entrepreneurs evolve over time. A restaurant owner may start offering delivery, or a freelancer might shift from graphic design to digital marketing. If your SBI code doesn’t evolve with you, your registration no longer reflects reality.

The 2025 update aims to better classify such modern activities. Still, it remains your responsibility to ensure your business description is accurate.

What You Can Do Now

• Prepare: Check now whether your current description is up to date.

• Verify after September: Once the update is live, log in and confirm everything is correct.

• Update if necessary: Submit any changes promptly to the KVK.

• Seek advice: If you’re unsure about the implications, consult your accountant or bookkeeper.
