Sole Proprietorship Status in Guam: Key Facts

Individuals can operate as sole proprietors, but no tailored or simplified framework exists, and there is no distinct alternative status specifically for micro-entrepreneurs.

Legal and Tax Steps for Individual Businesses in Guam

To establish and operate a sole proprietorship in Guam, individuals must obtain a business license from the Guam Department of Revenue and Taxation. This registration process is mandatory before commencing business activities. Once registered, all business income is reported together with the individual’s personal finances; no separate entity or separate corporate tax return is involved.

Income generated through a sole proprietorship is subject to Guam’s application of the U.S. Internal Revenue Code. This means all federal tax rates and rules used in the 50 U.S. states are also adopted in Guam unless specifically excluded.

Tax Regime and Filing

Guam does not provide a simplified or preferential tax regime for small businesses operating as sole proprietors. All income is integrated into the personal income tax filing process, following standard federal guidelines. From a liability perspective, the individual remains fully responsible for obligations and debts incurred by their business operation.

Actionable Pro Tips for Doing Business as a Sole Proprietor in Guam (2025)

  • Secure a Business License Early: Before initiating any commercial activity, complete the business license process with Guam authorities. Registration is mandatory and noncompliance may result in penalties.
  • Keep Meticulous Records: Since Guam follows federal tax filing rules, accurate bookkeeping will streamline the reporting process and help avoid mistakes during tax season.
  • Understand Tax Obligations: All earnings are taxed at U.S. rates in Guam. Without a separate legal entity, your full income and liabilities are tied to your personal finances—plan your estimated tax payments accordingly throughout the year.
  • Monitor for Regulatory Updates: While the Guam regime is stable, reviewing regulations annually ensures ongoing compliance and awareness of any potential changes.

Official Resources

No special sole proprietorship regime is available in Guam for 2025; instead, standard U.S. individual business rules apply with straightforward licensing and tax filing steps. The absence of a preferential or simplified status means business owners must ensure thorough compliance with the federal tax system as implemented in the territory. Keep in mind, all income and associated legal liabilities remain closely linked to your personal standing, underscoring the importance of diligent recordkeeping and familiarity with applicable obligations in Guam.
