San Marcos specifics
San Marcos has a combined sales and use tax rate of 8.75 percent as of October 1, 2026, one of the higher rates in the county because of a city district tax. Contractors who buy materials, retailers and restaurants should make sure purchases and sales are taxed correctly. Businesses operating in the city need a City of San Marcos business license, which is renewed annually.
California businesses deal with more state-level accounts than most. Sales and use tax is reported to the CDTFA at rates that vary by city within San Diego County, payroll includes State Disability Insurance and state unemployment insurance through the EDD, and LLCs owe annual tax and fees to the Franchise Tax Board. Books that track those liabilities correctly make filings simple and avoid surprise notices.
