What California asks of a business with a website

A few rules apply to any Mountain House business that sells or advertises online:

  • Under ADA Title III, a business open to the public should make its website usable by people with disabilities, according to the Justice Department’s guidance. ADA.gov guidance
  • Out-of-state sellers have to collect California sales tax once they reach the state threshold: more than $500,000 in combined sales of tangible personal property for delivery in California in the preceding or current calendar year (no transaction-count test). Revenue and Taxation Code section 6203
  • California’s statewide sales and use tax rate is 7.25%, and most areas add district taxes of roughly 0.10% to 2.00% on top of it. California Department of Tax and Fee Administration (CDTFA)
  • The California Consumer Privacy Act, as amended by the California Privacy Rights Act (CCPA/CPRA) exists, but its thresholds are high: For-profit businesses doing business in California that meet any one of three tests: gross annual revenue over $25 million; buying, selling or sharing the personal information of 100,000 or more California residents or households; or deriving 50% or more of annual revenue from selling California residents’ personal information. A typical small business (a local service company with a brochure site or a small store) meets none of them and is outside the CCPA – but CalOPPA still requires a privacy policy (see outras_leis_site). California Civil Code, Title 1.81.5 (Civ. Code 1798.100 et seq.)
  • San Joaquin County and the City of Mountain House may each charge a local business tax; ask both before you open. Official source
