Starting a business in Germany can feel overwhelming, especially when tax numbers enter the conversation. Many new entrepreneurs and Amazon sellers struggle to understand the differences between these numbers, and it’s no surprise — the German tax system has several variations that sound alike but serve different purposes. In this guide, I’ll walk you through each one, explain how they affect your Amazon business, and clear up the confusion once and for all.
Steuer-Identifikationsnummer (Steuer-ID): Your Lifetime Personal Tax ID
The Steuer-Identifikationsnummer, often shortened to Steuer-ID, is the personal tax identification number assigned to every German resident. If you are born in Germany, you automatically receive it at birth. If you move to Germany as a foreigner, you’ll be issued one once you register with your local Finanzamt (tax office).
This number is unique, permanent, and never changes throughout your lifetime, even if you move within Germany. Employers use it to report your wages, and the tax office uses it to track your personal income tax obligations.
When selling on Amazon, this is what Amazon often refers to as your citizen’s ID. If they request it, they are asking for your Steuer-ID.
Steuernummer: Your Business Tax Number
Next, we have the Steuernummer. Unlike the Steuer-ID, which is personal, the Steuernummer is issued by the Finanzamt when you either:
- Register a business, or
- File an income tax return as a freelancer or entrepreneur.
This number can change depending on your circumstances. For example, if you move from Hamburg to Berlin, you will receive a new Steuernummer from your new local tax office. Even within the same city, different districts are managed by different offices, so a simple move across postal codes could also result in a new number.
For married couples, a joint Steuernummer may also be issued for filing income taxes together.
In the Amazon ecosystem, when you’re asked to provide your business tax number, it’s the Steuernummer they are referring to.
Umsatzsteuer-Identifikationsnummer (USt-ID): The VAT Number
If you plan to trade across borders within the European Union, you’ll need an Umsatzsteuer-Identifikationsnummer (USt-ID), commonly called the VAT number.
This number always begins with a country code (for Germany, DE), followed by a string of digits. For France, it starts with FR, for Spain ES, and so on.
The VAT number plays a vital role in intra-EU transactions. It allows businesses and authorities to track cross-border trade, ensuring that VAT is applied correctly. For example, if you buy products from a French supplier, you’ll provide them with your German USt-ID so the transaction can be processed correctly.
Amazon requires sellers to provide their VAT number if they plan to do business at scale. Even if you are based in Germany, cross-border activity is inevitable when selling on Amazon, so it’s wise to register for your USt-ID early.

Kleinunternehmerregelung: The Small Business VAT Exemption
One concept that often confuses new sellers is the Kleinunternehmerregelung (small business regulation). If you expect to earn less than €22,000 in your first year, or under roughly €50,000–55,000 in your second year, you may qualify. Under this rule:
- You do not charge VAT on invoices.
- You are not required to file VAT returns.
While this sounds convenient, there’s a catch. For Amazon sellers, the Kleinunternehmerregelung can complicate matters significantly. Amazon often assumes sellers are VAT-registered, and its system may not handle the exemption smoothly. As a result, many sellers find themselves in a messy situation where VAT is miscalculated or overlooked.
For that reason, I usually recommend registering for a VAT number straight away, even if you qualify for the small business exemption. It saves you stress and aligns your business with Amazon’s requirements.
Putting It All Together for Amazon Germany
To summarize:
- Steuer-ID → Your personal lifetime ID (Amazon calls it your citizen’s ID).
- Steuernummer → Your business tax number (Amazon calls this your business tax ID).
- USt-ID (VAT Number) → Necessary for EU-wide trade and essential for Amazon sellers.
- Kleinunternehmerregelung → Avoid if selling on Amazon, since it creates complications.
If you’re serious about building a successful Amazon FBA business in Germany, having these tax numbers sorted is non-negotiable. They not only keep you compliant with German law but also ensure your Amazon account runs smoothly.
Frequently Asked Questions
1. Do I need all three numbers to sell on Amazon Germany?
Yes, in most cases. Amazon will ask for your Steuer-ID, Steuernummer, and VAT number (USt-ID). The Kleinunternehmerregelung may exempt you from VAT, but it often complicates selling on Amazon, so I recommend registering for VAT anyway.
2. What happens if I move cities in Germany?
Your Steuer-ID remains the same, but your Steuernummer will likely change since each local Finanzamt issues its own. Always notify your new tax office to stay compliant.
3. Can foreigners selling on Amazon Germany get these numbers?
Absolutely. Once you register in Germany, you’ll receive your Steuer-ID. You can then apply for your Steuernummer and VAT number as needed. Many foreign Amazon sellers operate successfully in Germany with these registrations.
4. Is the Kleinunternehmerregelung good for beginners?
It can work for freelancers or very small businesses, but for Amazon FBA sellers, it usually creates headaches. It’s better to start with a VAT number to avoid future issues.
