San Jose does not levy a local self-employment or income tax. San Jose charges a business tax based on the number of employees, with a base fee plus a per-employee amount that scales with company size.
Business expenses that lower net profit (equipment, software, home office, mileage) reduce both SE tax and income tax. The deductible half of SE tax, self-employed health insurance, and retirement contributions reduce income tax.
