The United States employs a complex progressive tax system administered by federal, state, and local authorities. California has one of the highest state income tax rates in the nation, with marginal rates reaching 13.3% for high earners, making San Diego's combined tax burden among the highest in the US. The US tax year runs from January to December, with federal returns typically due April 15th and California returns due the same date. For expatriates, the US system may be challenging as it taxes worldwide income regardless of residence location, though certain exclusions and credits may apply.
