San Diego Finance Guide 2026

San Diego is a California city of 1,406,106 people, which puts it in the category of a population over a million among the metros MONEYlume covers. San Diego residents face a top state income tax rate of 13.3%, well above the national median, which changes the math on where to hold taxable versus tax-deferred investments.

At a median of $980,000, San Diego homes cost roughly double the national median — renting versus buying is a much closer call here than in most US cities. The guides linked below turn all of this into specifics — real banks, real rates, real local rules — instead of national averages that don't apply to San Diego.
