San Francisco Just Changed Your Biz Renewal

If you renewed your San Francisco business registration last year, the process you used is gone. The city eliminated the standalone registration renewal form. Starting this year, you file a single Annual Business Registration and Tax Form that combines your registration renewal with your annual business tax return.

This happened because San Francisco voters approved Proposition M in November 2024. Prop M restructured the city’s business tax system and merged two previously separate filings into one. You can no longer split them up.

The SF Treasurer and Tax Collector put it plainly: “Beginning with the 2025 filing, all San Francisco businesses must renew their 2026-27 business registration in a combined return with the 2025 annual business tax. You can no longer file the business registration renewal separately as in prior years.”

The deadline for this new combined form is the last day of February each year. In 2026, February 28 falls on a Saturday, so the effective deadline is March 2, 2026. That date applies to every San Francisco business, regardless of size. Richardson CPA’s advisory on the new filing confirmed the adjusted date and the penalty risks for anyone who misses it.

Under $5 Million? You’re Probably Just Checking a Box

The combined form looks like it’s asking you to do more. For most small businesses, it isn’t. If your business had $5 million or less in San Francisco gross receipts last year, you likely owe zero additional taxes. “SF gross receipts” means the revenue tied to your San Francisco operations specifically, not your total company revenue everywhere.

The SF Treasurer confirmed this directly: “Most small businesses will only renew the registration and will not file or pay additional business taxes.” The form has exemption sections you check off and move on. As the chart below shows, other thresholds reinforce how far away most small businesses are from owing anything extra. The Commercial Rents Tax doesn’t kick in until $2.325 million in combined taxable SF gross receipts. The Homelessness Gross Receipts Tax only applies above $25 million.

One thing that trips people up: being exempt from taxes does not mean you skip the form. You still file. You still meet the March 2 deadline. You just won’t owe anything beyond the registration renewal fee itself.

Three Things You Need Before You Log In

Before you go to sftreasurer.org, have these three items ready:

Check your prior year notices from the Treasurer’s office for the account number and PIN. If you can’t find them, call the office directly. The SF Treasurer’s instructional video, published February 2, 2026, walks through the full login and filing process on screen.

The Extension Covers Your Taxes. It Doesn’t Cover Your Registration.

Here’s where people are going to get burned this year. The new combined form has two parts: registration renewal and tax filing. If your business qualifies, you can extend the tax filing portion to November 30, 2026. That aligns with California’s state deadline.

Think of it like filing a federal tax extension. You can push your return to October, but you still owe estimated taxes by April 15. Same idea here. The tax paperwork can wait if you qualify. The registration cannot.

As Richardson CPA warned in their advisory: “Failure to meet these deadlines will result in penalties, interest, and fees.” Don’t assume the extension covers everything just because the form is combined. It doesn’t.

One Bill Instead of Two

A quick word on why this changed. Proposition M was a ballot measure, which means San Francisco voters decided on it directly. They approved it in November 2024. It restructured how the city collects business taxes and how businesses interact with the Treasurer’s office.

The simplest way to think about it: San Francisco used to make you pay your electric bill and water bill to the same utility company, but on different dates, with different forms, through different logins. Prop M merged them into one bill, one form, one deadline. Long-term, that’s simpler. Short-term, the transition caught a lot of business owners off guard because the process they relied on disappeared without much warning.

This isn't a pilot program. It's the permanent structure going forward. Every February, you'll file this combined form.

You Don’t Have to Be in San Francisco for This to Bite You

San Francisco made national news because the change was big and the deadline is soon. But cities and counties across the country have their own business registration renewals, license renewals, and local tax calendars. Many update their rules quietly. A deadline shifts. A form merges. A fee changes. And nobody sends you a push notification.

Missing a local renewal isn’t just about fines. In some places, a lapsed registration means you lose good standing with the state. You might not be able to pull permits for a new office or job site. In certain jurisdictions, you can’t enforce your own contracts if your business registration isn’t current. That’s a real operational risk, not just a paperwork headache.

A good rule of thumb: once a year, search “[your city] business registration renewal deadline” and “[your county] business license renewal.” Whatever dates come up, put them in your calendar.

The One-Hour Compliance Calendar

This week, set aside one hour. Look up four things and add each one to your calendar with a 30-day advance reminder:

That’s the whole list. Four items. Four calendar entries. Four reminders set 30 days early so you’re never scrambling the week before a deadline you forgot existed.

If you already work with a CPA or a registered agent, ask whether they track your local deadlines. Some do. Many only watch federal and state dates. It’s worth a quick email to find out what’s covered and what falls on you.
