Full Breakdown

SDMC §31.0301 sets the general business tax classification: any business, trade, or profession "not specifically taxed by any other business tax code" pays $125 annually plus $5 per employee, or a flat $125 plus $5 per independent contractor for out-of-town companies using local agents. Businesses with twelve or fewer employees pay a reduced $34 flat tax under later subsections. Separate classifications exist for residential rental real estate (§31.0305), refuse collectors (§31.0306), trailer/mobile home parks (§31.0307), and swap meets and trade shows (§31.0308), each with its own rate structure administered by the City Treasurer.

Violations & Fines

Engaging in business without obtaining the required business tax certificate is a misdemeanor under §31.0121; unpaid taxes become a debt to the City collectible by suit under §31.0122, plus delinquency surcharges of $68 to $250 under §31.0301(f).

Frequently Asked Questions

Does every San Diego business pay the same tax rate?
No. Most pay $125 plus $5 per employee under §31.0301, but rental housing, refuse collection, trailer parks, and swap meets have their own separate classifications and rates.
Is San Diego's business tax based on revenue?
No, it's a flat per-business charge plus a per-employee amount under SDMC §31.0301, not a percentage of gross receipts.
