Introduction

In Germany, Tax Identification Numbers (TINs) are essential for individuals and businesses to ensure compliance with tax regulations. These unique identifiers facilitate accurate tax reporting and administration. All information presented here is verified from official tax authority websites and trusted government sources.​Taxation and Customs Union 

Tax Identification Number Types 

Germany utilizes several types of tax identification numbers:​ 

  • Steuerliche Identifikationsnummer (Steuer-ID): An 11-digit personal tax identification number assigned to individuals.​germantaxes.de 
  • Steuernummer (Tax Number): A unique number assigned to individuals and businesses for local tax purposes.​ 
  • Umsatzsteuer-Identifikationsnummer (USt-IdNr.): A VAT identification number used by businesses for intra-European Union transactions.​ 

TIN Format and Structure 

  • Steuer-ID: Consists of 11 digits in the format 12 345 678 901. This number is unique, permanent, and does not contain any personal information. ​
  • Steuernummer: The format varies by region but generally follows a pattern such as 12/345/67890. It includes information about the local tax office and the taxpayer. ​ 
  • USt-IdNr.: Comprises the country code ‘DE’ followed by 9 digits, e.g., DE123456789.

Issuing Authority and Registration Process 

  • Steuer-ID: Issued automatically by the Federal Central Tax Office (Bundeszentralamt für Steuern, BZSt) to all residents upon registration in Germany. If lost, it can be requested online.
  • Steuernummer: Assigned by the local tax office (Finanzamt) where the individual or business is registered. Applicants need to submit a completed tax registration form along with identification documents. The process may vary by region.
  • USt-IdNr.: Businesses can request this number during their tax office registration. For already registered businesses without a USt-IdNr., an online application is available through the BZSt.

TIN Verification and Lookup 

  • Steuer-ID: Individuals can retrieve their Steuer-ID through the BZSt’s official website if it’s misplaced. ​ 
  • USt-IdNr.: The European Commission provides an online tool, the VAT Information Exchange System (VIES), for verifying VAT numbers across EU member states. ​

TIN and VAT Number Connection 

In Germany, the Umsatzsteuer-Identifikationsnummer (USt-IdNr.) serves as the VAT identification number. It is distinct from the Steuer-ID and Steuernummer and is specifically used for intra-EU transactions.

Why Accurate TIN Validation Matters 

Ensuring the accuracy of your TIN is critical for both businesses and individuals in Germany. An incorrect or unverified TIN can lead to serious complications such as: 

  • Delays in tax processing 
  • Rejection of tax exemption claims 
  • Fines and penalties for non-compliance 
  • Rejection of e-invoicing submissions 
  • Onboarding unqualified suppliers or customers 
  • Data quality issues across finance and compliance systems
