A proposal to reform San Francisco’s business tax formula is being considered for approval by voters in November. The proposal would modify the gross receipts tax to focus on a company’s sales instead of its on-site headcount, potentially leading to tax cuts for small businesses and making it more attractive for large companies to keep their workers in the city. The plan is expected to be revenue neutral over time, with initial declines in business tax revenue before increases in the following years. The proposal would also raise the threshold for exemption from gross receipts taxes for small businesses. The effort to reform the tax structure has gathered momentum over the past year and has involved major San Francisco employers, labor unions, and other stakeholders in negotiations. Labor unions are not expected to actively oppose the measure’s passage.
