San Diego specifics
Every business operating inside city limits needs a City of San Diego Business Tax Certificate, renewed annually, in addition to state registrations. Sales tax rates inside the city differ from some neighboring cities because of district taxes, so multi-location retailers and restaurants should confirm the CDTFA rate for each address.
California recognizes the federal S election but still taxes the corporation itself at 1.5 percent of net income, with an $800 minimum franchise tax. That entity-level tax belongs in any comparison between S corporation and LLC or partnership treatment.

S corp tax preparation questions from San Diego owners
When is our S corporation return due?
March 15 for calendar-year companies. We aim to deliver K-1s early so owners can file their personal returns on time.
What is the California S corporation tax?
1.5 percent of net income with an $800 minimum, paid by the corporation, in addition to the tax shareholders pay on their K-1 income.
Do you track shareholder basis?
Yes. Basis determines whether losses can be deducted and whether distributions are taxable, so we keep a schedule for each shareholder.
