San Francisco, Startups and Taxes

San Francisco was rated the best city in the US to launch a startup in 2023, according to Fast Company. The city is home to more than 8,000 tech startups. It’s easy to see why startups are attracted to San Francisco’s booming startup economy, since San Francisco offers a culture of innovation, lots of talented employees, world-class universities, and an extensive network of venture capital investors. But, the local government doesn’t hold back on creating taxes and other, unique governmental filings that impact many of the startups that call it home. 

The most important taxing authorities for companies in San Francisco are: 

In 2024, San Francisco has many unique corporate tax deadlines beyond the traditional April 15th tax return date. Important filing deadlines include the San Francisco Gross Receipts filing deadline of February 28 and the April 1st business property tax filing. Estimated tax payments due dates include April 30th, July 31st, and October 31st. See the calendar above for a more complete list.

San Francisco Corporate Taxes

San Francisco has a reputation of… how shall we say.. not being afraid to level taxes on businesses. These are in addition to the California corporate taxes, which are a flat 8.84% in 2023 (connect with your tax advisor, as this corporate rate may vary depending on your business’ entity type and industry; most tech startups that we work with in SF will pay around 8.84%). SF also has a gross receipts tax, which levels taxes on the revenue a business earns – this is different than the federal or California tax rates, which are based on taxable income.  

SF Gross Receipts Tax

The San Francisco Gross Receipts Tax is a tax on the gross receipts of businesses operating within the city of San Francisco. The tax rate varies depending on the type of business and the amount of gross receipts. The tax is typically reported and paid on a quarterly basis. The allocation of gross receipts to San Francisco for taxation purposes varies according to the taxpayer’s business type. It is determined by the gross receipts coming from customers in SF, the payroll expenses for employees in the city, or a mix of both factors. Of course, then the next question is “what are gross receipts?”

What are Gross Receipts?

Basically, revenue earned in San Francisco. According to the SF Treasurer’s office, gross receipts are “Gross receipts include but is not limited to all amounts that constitute gross income for federal income tax purposes. Gross receipts, including advance payments, shall be included in a taxpayer’s gross receipts at the time such receipts are recognized as gross income for federal income tax reporting purposes.”

San Francisco’s Homelessness Gross Receipts Tax

This is a unique tax to SF; thankfully there is a revenue minimum that makes it not apply to most startups. San Francisco’s Homelessness Gross Receipts Tax applies an extra tax to the majority of businesses that generate more than $50 million in gross annual receipts within the city. Additionally, businesses that opt for the payroll tax under the alternative “administrative office” tax structure are also liable for an extra 1.5% payroll tax. For businesses and consolidated groups that have gross annual receipts exceeding $50 million from San Francisco sources, this tax introduces an added rate between 0.175% and 0.690%, which varies based on the type of business.

San Francisco Overpaid Executive Gross Receipts Tax

Thankfully, this is another SF tax that doesn’t impact most startups. Starting with the 2022 tax year, San Francisco has introduced an additional tax targeting companies with significantly high executive compensation, known as the “Overpaid Executive Gross Receipts Tax.” This tax is activated when the pay ratio between the company’s highest-paid managerial employee, regardless of their location, and the annualized median compensation of both full-time and part-time employees in San Francisco, exceeds 100:1. Compensation for this calculation includes a wide range of earnings like bonuses and stock options. Companies with an executive pay ratio above this threshold will face an extra tax on their San Francisco gross receipts, which varies from 0.1% to 0.6%, based on the specific pay ratio.
