California Franchise Tax Notices: What Every LLC and S Corp Owner Needs to Know in 2025
This information is current as of 8/14/2025. Tax laws change frequently. Verify updates with the IRS or FTB if reading this later.
Every year, more than 150,000 California businesses get blindsided by California franchise tax notices—from reminders to penalties. If you think this is just a “paperwork hassle,” you’re missing the real risk: hidden fees, sudden bank levies, and the FTB’s growing database of enforcement triggers. In the past 12 months, small missteps have cost California business owners up to $6,400 per incident—often due to one careless deadline or assuming exemption when you’re not. Here’s the reality: with FTB enforcement projected to reach record levels this tax year, smart owners need to ditch the panic and adopt proactive, compliance-first strategies.
Fast Tax Fact
California’s franchise tax is a minimum $800 annual fee for every LLC or S Corp that does business in the state—regardless of profit. Skipping it for even one year exposes you to penalties up to 25% of the tax due, plus interest and a “demand for tax return” notice that can trigger audits, license suspension, and even bank account levies.
The Franchise Tax Board’s Enforcement Playbook for 2025
Quick answer: In 2025, the FTB is harnessing new automation—matching your business filings and banking activity against Secretary of State data, IRS filings, and even social media accounts. If you’re a California LLC or S Corp with any financial footprint (bank account, payroll, 1099s), you’re on their radar. Delayed filings or missed minimum payments now mean a warning, then a penalty, then an account freeze—all within as little as 90 days. If your business is classified as “suspended,” you lose the right to do business, open new accounts, or access the courts until every notice and fee is cleared.
FTB compliance isn’t just about paying $800 annually—it’s about maintaining year-round good standing (filed tax returns, paid all old fees, resolved ancient notices), which means watching for and addressing every notice immediately. Check your business mailing address and online account monthly. One undelivered FTB notice is enough to suspend your entity without you even knowing.
What Counts as Doing Business? (Common Traps Most Miss)
Here’s why hundreds of LLC and S Corp owners are caught off guard every spring: California defines “doing business” far more broadly than most states. Just signing a lease, holding a bank account, or making a single sale in the state triggers franchise tax obligations—even for out-of-state LLCs and S Corps.
- If your business is formed in California—even if dormant—you owe the franchise tax.
- Operate physically or virtually in CA? Franchise tax applies.
- Out-of-state entity with a CA customer, property, or agent? You almost certainly owe it, even if your home state doesn’t have this rule.
Failing to pay by the deadline (usually April 15th for calendar-year filers, 15th day of the 4th month after year-end for everyone else) gets you a “demand for tax return” or “final notice” from the FTB. This spiral quickly leads to suspension and accumulating penalties, all while you lose the right to enforce contracts or defend against lawsuits.
How to Avoid a Franchise Tax Notice—and What to Do if You Get One
Don’t ignore the envelope: most FTB notices—including late payment warnings—carry a hard deadline, after which penalties double, and interest starts accruing on a daily basis. If you get a notice:
- Act within 30 days for most warnings; some give you as little as 15 days to respond before escalation.
- Log in to your MyFTB online portal to review account status and pay any outstanding amounts.
- If your entity is “suspended,” resolve all open issues, file missing returns, and pay penalties—then file Form 3557 to request reinstatement.
- Use our tax notice and audit defense guide to get step-by-step help resolving notices and avoiding suspension traps.
For many small business owners, the most dangerous trap is mailing a check or correspondence to the wrong address or failing to update your SOS and FTB records after moving. One undelivered FTB notice starts the penalty clock and can suspend you even if your online account shows good standing.
Case Study: How One LLC Owner Slashed $6,000 in Avoidable Franchise Tax Penalties
Marissa—a Riverside, CA ecommerce LLC owner—thought her business was “on hold” while she took a year off. She stopped making franchise tax payments after shuttering sales, never filed formal dissolution paperwork, and assumed that lack of activity meant there were no obligations for 2024. In spring 2025, she received a series of FTB “demand for tax return” notices that spiraled into entity suspension, a $6,400 penalty bill, and a threatened bank levy. KDA ran a three-step rescue: we 1) filed past-due returns, 2) negotiated to reduce penalties using FTB’s reasonable cause rules, and 3) submitted formal dissolution documentation. Marissa ended up paying $2,000 total—an instant $4,400 savings—and got her LLC out of FTB crosshairs permanently.
Pro Tip: Franchise Tax Compliance Is Year-Round—Not Just at Tax Deadline
If you wait for a notice before paying or checking status, you’re already behind. Set recurring calendar reminders to check your MyFTB portal quarterly, especially before hiring, opening accounts, or entering new contracts. FTB suspensions are now flagged by credit agencies and can block you from getting loans or business insurance until cleared.
Why Most Owners Miss Critical Notice—and How to Never Miss One Again
The single biggest error? Relying on paper mail, which is slow and unreliable. Update your business mailing and email addresses in both your SOS and FTB profiles. Opt into electronic notices and set up SMS/email alerts via MyFTB. Have a compliance partner or accountant review your MyFTB portal monthly—this $75 service can save you five figures if a notice slips through.
Still using paper checks? Slow mail can trigger a “late” status even if you sent payment on time. Always pay online, get an instant confirmation, and download proof of submission, especially near the deadline.

FAQs: Your Franchise Tax Notice Questions Answered
What if my LLC or S Corp hasn’t made any money this year?
You still owe the $800 minimum tax, unless you are a newly-formed LLC (exempt the first year only). The FTB does not care if your profits are $0. Forgetting this is a common mistake that leads to “demand” notices and suspension. Check your exemption status directly via the FTB’s official site.
How do I resolve an FTB suspension?
First, log in to your MyFTB account and pull your account history. Second, pay any past-due fees or penalties. Third, file all missing returns. When done, submit Form 3557 via the FTB portal to request reinstatement. Processing usually takes 4–8 weeks if all paperwork is in order.
What IRS forms should I track for California franchise tax compliance?
Track Form 1065 (LLC partnerships) and 1120/1120S (for S and C Corps). But remember: the FTB’s requirements and deadlines are separate from federal IRS rules. FTB can suspend you even if your federal filings are perfect. See the IRS business structures resource for entity-specific rules.
KDA Case Study: Bay Area S Corp Reactivates, Saves $9,300 in Penalties
James, a Bay Area tech consultant running his own S Corp, let his company’s good standing lapse after missing franchise tax payments during the pandemic. He incorrectly assumed “business inactivity” meant he could ignore FTB notices for a year. By 2025, his S Corp was suspended—he faced a combined penalty and interest bill of $9,300, plus loss of state contracts and legal standing. KDA’s compliance team stepped in, filed the appropriate returns, secured penalty abatement under new 2025 reasonable cause standards, and had the corporation reinstated in under four weeks. James paid $3,500 in back taxes and fees for total reinstatement—securing state contracts worth $74,000 and restoring his legal right to do business. James’s ROI was over 20x in a single year.
Red Flag: Ignoring an FTB Franchise Tax Notice Means Big Risk
Ignoring or delaying an FTB notice is now a fast track to forced suspension and serious cash consequences. The FTB automates entity suspensions, making it harder than ever to claim ignorance or fix things without penalty. Suspended businesses can’t sue, collect payments, or protect their IP in California courts. See the state’s penalty notice explainer for current enforcement policy.
Get Out of Notice Purgatory—Don’t Wait for Penalties
Proactive compliance isn’t expensive—inaction is. Most clients spend $750–$2,500 for KDA’s full compliance and penalty response, with savings that routinely exceed $5,000 per incident. Don’t try to play catch-up alone—most business owners miss critical filings, deadlines, or opportunities for penalty abatement.
