American Samoa Tax ID Number (TIN) Guide 

Introduction

In American Samoa, the Tax Identification Number (TIN) is a unique identifier assigned to individuals, businesses, and legal entities for tax purposes. Accurate possession and use of the correct TIN are essential for compliance with American Samoa’s tax regulations, which are overseen by the American Samoa Tax Office. All information provided here is verified from official sources, including the American Samoa Tax Office and relevant U.S. federal tax authorities. 

Tax Identification Number Types 

American Samoa uses the following official types of TINs: 

• Social Security Number (SSN): Assigned to individuals residing in American Samoa, the SSN is used for tax reporting and identification purposes. 

• Employer Identification Number (EIN): Used for businesses and other legal entities operating in American Samoa, this number is issued by the Internal Revenue Service (IRS) and is required for federal tax purposes. 

These identifiers ensure proper tax compliance for both individuals and entities in American Samoa. 

TIN Format and Structure 

• Social Security Number (SSN): 
  Format: XXX-XX-XXXX 

• Nine digits divided into three parts by hyphens. 

• Used for individual taxpayer identification. 

• Employer Identification Number (EIN): 
  Format: XX-XXXXXXX 

• Nine digits with a hyphen after the first two digits. 

• Used to identify businesses and entities for tax purposes. 

Both formats follow the standard U.S. tax ID conventions as American Samoa is a U.S. territory. 

Issuing Authority and Registration Process 

• The American Samoa Tax Office administers local tax laws and oversees tax registrations. 

• The Internal Revenue Service (IRS) issues SSNs and EINs for federal tax purposes, including those applicable in American Samoa.

TIN and VAT Number Connection 

American Samoa does not have a separate VAT system like many other countries. Instead, tax collection relies primarily on federal income tax identification numbers (SSN and EIN). Therefore, the SSN and EIN serve as the primary tax identification for individuals and businesses, respectively. 

Why Accurate TIN Validation Matters 

Ensuring the accuracy of your TIN is critical for both businesses and individuals in American Samoa. 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
