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.
