If you run a small business in California, understanding sales tax isn’t optional — it’s mandatory. From brick-and-mortar shops in Fremont to online sellers on Shopify, Amazon, or Etsy, every business owner needs to know what sales tax to collect and how to report it properly.

California’s tax laws are among the most complex in the U.S., and failing to comply can lead to penalties, audits, and unnecessary stress. The good news? With the right knowledge — and the right partner — you can stay compliant and focus on growing your business.

What Exactly Is California Sales Tax?

Sales tax in California is a consumption tax applied to the sale of tangible goods and some services. While the statewide base rate is 7.25%, local county and city rates can add more.

As a small business, you’re responsible for:

• Registering for a seller’s permit
• Collecting the correct tax rate based on customer location
• Reporting & remitting taxes to the California Department of Tax and Fee Administration (CDTFA)
• Common Sales Tax Challenges for California Businesses

Charging the wrong tax rate due to county/city variations

• Misunderstanding marketplace collection rules (Shopify, Amazon, Etsy)
• Missing tax deadlines and filing late returns
• Failing to register for a seller’s permit
• Not separating taxable vs. non-taxable items correctly

Fact: The CDTFA collected over $50 billion in sales tax last year, and small business audits are on the rise.

Why California Sales Tax Is More Complex Than Other States

• Different rates per county/city (Los Angeles vs. Fremont vs. San Diego)
• Special exemptions for certain industries (food, healthcare, manufacturing)
• Marketplace facilitator rules (Amazon, Etsy, eBay collect for you — but you may still need to file)
• Use tax requirements (for goods bought out-of-state and used in California)
• Nexus laws — if you sell to California from another state, you may still owe tax

How to Stay Compliant With California Sales Tax

Step 1: Get a Seller’s Permit — Apply with CDTFA before making taxable sales
Step 2: Track Sales by Location — Use bookkeeping software that maps sales tax rates
Step 3: File on Time — Monthly, quarterly, or annually depending on sales volume
Step 4: Understand Marketplace Rules — Even if platforms collect tax, filing may still be required
Step 5: Work With a Tax Professional — Especially if you operate across multiple cities or online platforms
