California sales tax rates 2026: Calculator, nexus, and due dates

California sales tax rates by city and county

California’s sales tax structure is layered. The 7.25% state base rate applies everywhere, but counties, cities, and special districts add their own local sales tax rates on top — meaning the combined rate can vary significantly by location.

Because California is a destination-based state, you charge the rate based on where your customer receives the product, not where your business is located.

A sale shipped to Los Angeles requires 10.25%, while a sale shipped to San Diego requires 7.75%. California centralizes all filings with the CDTFA, so you only file one return regardless of how many jurisdictions you sell into.

Major California cities and their 2026 combined rates:

California nexus thresholds

Every business with customers in California is subject to nexus laws. You are required to register and collect sales tax if you trigger “nexus” through a physical presence in the state or by exceeding specific economic thresholds as a remote seller.

California economic nexus

You will trigger California economic nexus if you exceed the following thresholds in the current or previous calendar year:

• Sales threshold: $500,000 in total gross sales (including marketplace sales)
• Transaction threshold: None (California is dollar-volume only).

California physical nexus

You have physical nexus (and must register from dollar one) if you have:

• Inventory: Storing goods in a 3PL or Amazon FBA warehouse in California.
• Personnel: Remote employees, contractors, or sales reps based in the state.
• Property: Leasing tangible property like physical offices, stores, or sample rooms.

Registering for a California tax permit

Once you trigger nexus, you must register with the California Department of Tax and Fee Administration (CDTFA) before you can legally collect sales tax. Operating without a permit after crossing the threshold exposes you to back taxes, penalties, and interest from the date nexus was established — not the date you registered.

1. Gather your information. You’ll need your FEIN, estimated annual sales, business structure details, and bank account information.
2. Submit your application. Use the CDTFA’s Online Services portal to apply for your Seller’s Permit. Most applications are approved immediately or within a few business days.
3. Note your effective date. California requires you to begin collecting sales tax on the date nexus was triggered — not the date you registered. If there’s a gap, you may owe back taxes for that period.

If you have questions about your California registration or compliance history, TaxCloud’s U.S.-based support team typically responds within 2 hours and can review your setup directly.

Understanding California sales tax calculations

California’s calculation rules are straightforward compared to states with home rule complexity — but destination-based sourcing and marketplace reporting requirements trip up sellers who are new to the state.

What is taxable in California?

Taxability in California is determined by how a product is classified under state law. Below is a high-level summary for 2026:

• Tangible personal property: Most physical goods — such as furniture, electronics, and standard retail items — are subject to sales tax unless a specific exemption applies.
• Digital products, software, and SaaS: California generally does not tax digital goods (eBooks, music) and Software as a Service (SaaS). For more, read our guide to California SaaS Sales Tax.
• Food and groceries: California typically exempts grocery staples. However, prepared or heated food sold for immediate consumption is generally taxable.
• Clothing: Clothing and footwear are generally taxable at standard state and local rates.

What is tax exempt in California?

California provides sales tax exemptions for essential goods and specific categories:

• Essential exemptions: California provides specific exemptions for items such as prescription medications, diapers, and menstrual hygiene products.
• Additional exemptions: Most groceries (excluding hot prepared food), cold prepared food sold to-go, certain medical devices, and purchases made with CalFresh benefits are also exempt from sales tax.

California sales tax due dates and filing frequency

Filing frequency is assigned by the CDTFA based on your reported or estimated sales volume. In California, sales tax returns are generally due on the last day of the month following the reporting period.

Critical 2026 compliance notes:

• The “prepay” trap: If your tax liability exceeds $17,000 per month, California moves you to a “Quarterly Prepay” schedule. You must make two prepayments (due on the 24th of the first two months) before filing your final quarterly return.
• Zero-return requirement: If you are registered but had $0 in sales this period, you must still file. Failure to file a “Zero-Tax” return is the #1 cause of unnecessary “Forgetfulness Penalties” for ecommerce founders.
• Weekend rule: If the due date falls on a weekend or state holiday, your return is due the next business day.
