Steuer-ID, Steuernummer, and USt-IdNr. What’s the Difference?
In Germany, navigating the tax system requires understanding several identification numbers, each serving unique functions for individuals and businesses. This detailed guide clarifies the differences between the Tax Identification Number (Steuer-ID), the Tax Number (Steuernummer), and the VAT Identification Number (Umsatzsteuer-Identifikationsnummer or USt-IdNr.).
Tax Identification Number (Steuer-ID)
Purpose
The Steuer-ID is a permanent, personal identifier used by German tax authorities to track your tax-related activities.
Key Features
Format: 11-digit number (e.g., 12 345 678 901).
Issuer: Federal Central Tax Office (Bundeszentralamt für Steuern).
Permanence: It never changes, even if you relocate or change your employment status.
Use Cases: Needed for employment contracts, opening bank accounts, claiming child benefits, and interacting with public authorities.
Obtaining Your Steuer-ID
You receive your Steuer-ID automatically after registering your address (Anmeldung) in Germany. If misplaced, it can be requested from the Federal Central Tax Office.
Tax Number (Steuernummer)
Purpose
The Steuernummer is primarily used for tax declarations, tax payments, and interactions with local tax authorities (Finanzamt).
Key Features
Format: Usually 10-13 digits, structured differently across regions (e.g., 133/8150/8159).
Issuer: Local tax office (Finanzamt).
Variability: Can change if you move to a new tax district or alter your business structure.
Use Cases: Essential for submitting tax returns, particularly for freelancers, self-employed individuals, and businesses.
Obtaining Your Steuernummer
Issued after completing and submitting the tax registration questionnaire ("Fragebogen zur steuerlichen Erfassung") to your local Finanzamt.
VAT Identification Number (Umsatzsteuer-Identifikationsnummer or USt-IdNr.)
Purpose
The USt-IdNr. is necessary for businesses conducting cross-border transactions within the European Union (EU), primarily for VAT-related procedures.
Key Features
Format: Country code followed by 9 digits (e.g., DE123456789).
Issuer: Federal Central Tax Office (Bundeszentralamt für Steuern).
Use Cases: Required for invoicing international EU clients, reporting VAT within the EU, and claiming VAT refunds across member states.
Obtaining Your USt-IdNr.
Request your USt-IdNr. through the Federal Central Tax Office’s online portal, often simultaneously with your business registration.
