Gross receipts taxes are poorly structured taxes. Because they tax all business transactions throughout the supply chain, they create a pyramiding effect that penalizes more complex industries, e.g., an aircraft manufacturer probably gets taxed more than a local dairy. I don't know whether the things the SF government wants to spend the money on will help with the homelessness problem or not; but I do think there are better types of taxes to raise that money.
