Learn about tax regulations for employers and employees in American Samoa

Updated on April 27, 2025

Navigating the complexities of employment taxes is a critical aspect of operating a business, particularly in unique jurisdictions like American Samoa. Employers bear significant responsibilities for withholding taxes from employee wages and contributing their own share to local social programs. Understanding these obligations is essential for compliance, avoiding penalties, and ensuring smooth operations when employing individuals in the territory.

The tax system in American Samoa is administered by the American Samoa Government's Department of Treasury. It is based on a modified version of the U.S. Internal Revenue Code, adapted to the specific needs and circumstances of the territory. Both employers and employees have distinct tax responsibilities that must be met throughout the year.

Employer Social Security and Payroll Tax Obligations

Employers in American Samoa are required to contribute to the local social security system, often referred to as the American Samoa Social Security System (ASG-ASSS). This system provides retirement, disability, and survivor benefits to eligible residents.

The employer's contribution is a percentage of the employee's gross wages, up to an annual wage base limit. The employee also contributes a matching percentage, which the employer withholds from their pay.

Tax Type Employer Rate Employee Rate Annual Wage Base Limit (2025 - estimate)
American Samoa Social Security [Rate]% [Rate]% $[Amount]

Note: Specific rates and the wage base limit for 2025 are subject to legislative confirmation and may differ slightly from previous years. Employers should verify the current rates with the ASG Department of Treasury.

Employers are responsible for calculating both their contribution and the employee's withholding, remitting these amounts along with required reports on a regular basis (typically quarterly).

Income Tax Withholding Requirements

Employers are mandated to withhold American Samoa income tax from their employees' wages. The amount of tax to be withheld depends on several factors, including the employee's filing status, the number of withholding allowances claimed on their Form AS-A4 (similar to the U.S. W-4), and their wage amount.

American Samoa utilizes a progressive income tax system, meaning tax rates increase as income rises. Employers use withholding tables provided by the ASG Department of Treasury to determine the correct amount of tax to deduct from each payroll.

While specific tax brackets and rates for 2025 should be confirmed with the ASG Treasury, the structure generally involves multiple brackets with increasing marginal tax rates.

Taxable Income Bracket (2025 - estimate) Tax Rate (estimate)
Up to $[Amount 1] [Rate 1]%
Over $[Amount 1] to $[Amount 2] [Rate 2]%
Over $[Amount 2] to $[Amount 3] [Rate 3]%
Over $[Amount 3] [Rate 4]%

Note: These brackets and rates are illustrative based on typical progressive tax structures and should be verified with official 2025 ASG tax publications.

Accurate withholding is crucial. Under-withholding can result in employees owing significant taxes at year-end, while over-withholding can unnecessarily reduce employee take-home pay. Employers must ensure they have a current Form AS-A4 on file for each employee and apply the correct withholding calculations.

Employee Tax Deductions and Allowances

Employees in American Samoa may be eligible for various deductions and allowances that reduce their taxable income. While employers are primarily concerned with applying the correct withholding based on the AS-A4 form, understanding these potential deductions is helpful context.

Common deductions and allowances available to employees may include:

  • Standard Deduction: A fixed amount that can be claimed instead of itemizing deductions. The amount varies based on filing status (e.g., Single, Married Filing Jointly).
  • Personal Exemptions/Allowances: An amount claimed for the taxpayer, spouse, and dependents. These are reflected in the allowances claimed on the AS-A4 form, which directly impacts employer withholding.
  • Itemized Deductions: Certain expenses may be deductible if they exceed a certain threshold and the employee chooses not to take the standard deduction. These can include medical expenses, certain taxes, home mortgage interest, and charitable contributions.
  • Specific Credits: American Samoa's tax code may also include various tax credits that can reduce an employee's final tax liability.

Employees claim these allowances and deductions when filing their annual income tax returns. The number of allowances claimed on the AS-A4 form instructs the employer on how much income to effectively exempt from withholding for each pay period.

Tax Compliance and Reporting Deadlines

Employers in American Samoa must adhere to specific deadlines for reporting wages and remitting withheld taxes and employer contributions. Failure to meet these deadlines can result in penalties and interest.

Key reporting requirements and typical deadlines include:

  • Quarterly Reports (Form AS-WT): Employers must file a quarterly withholding tax return reporting total wages paid, income tax withheld, and ASG-ASSS contributions (both employer and employee shares). This report is typically due by the last day of the month following the end of the quarter (e.g., April 30 for the first quarter).
  • Annual Wage and Tax Statements (Form AS-W2): Similar to the U.S. W-2, employers must provide each employee with a statement summarizing their annual wages and taxes withheld by January 31st of the following year. Copies must also be filed with the ASG Department of Treasury by the same deadline.
  • Annual Reconciliation (Form AS-W3): Employers must file an annual reconciliation summarizing all quarterly filings and W-2 information. This is typically due by January 31st.

Employers are generally required to make tax deposits (withheld income tax and ASG-ASSS contributions) on a periodic basis, often monthly or semi-weekly, depending on the total amount of tax liability. Specific deposit schedules are provided by the ASG Department of Treasury.

Special Tax Considerations for Foreign Workers and Companies

Employing foreign workers or operating as a foreign company in American Samoa introduces additional tax considerations.

  • Residency Status: The tax treatment of foreign workers depends heavily on their residency status in American Samoa. Non-resident aliens are generally taxed only on income earned from sources within American Samoa, often at a flat rate unless a tax treaty applies (though treaties are less common for U.S. territories). Resident aliens are taxed on their worldwide income, similar to U.S. citizens and residents. Employers must determine the correct residency status for withholding purposes.
  • Withholding for Non-Residents: Specific withholding rules apply to payments made to non-resident aliens, including wages and other types of income. The withholding rate may differ from that for residents.
  • Foreign Companies: Foreign companies operating in American Samoa may be subject to corporate income tax on income effectively connected with a trade or business within the territory. They may also have withholding obligations on certain payments made from American Samoa sources, even if those payments are not wages (e.g., payments for services).
  • Compliance: Foreign entities and employers of foreign workers must ensure they comply with all ASG tax registration, reporting, and payment requirements applicable to their specific situation. This may involve obtaining a local business license and taxpayer identification number.

Navigating these specific rules requires careful attention to detail and potentially consultation with tax professionals familiar with American Samoa's unique tax code. An Employer of Record service can significantly simplify compliance for foreign companies employing workers in the territory by handling all local payroll, tax withholding, and reporting obligations.
