California Sales Tax on Invoices: A Practical Guide
Last verified: · Sales-tax rates and nexus thresholds change; verify with the California Department of Tax and Fee Administration before relying on any specific rate or rule.
California has the highest base state sales tax rate in the United States — 7.25% statewide — and one of the most complex local-rate frameworks. For a small business or out-of-state seller invoicing California customers, the practical questions are: do you have to collect California sales tax, what rate do you charge, and what does that look like on the invoice? This guide answers each in plain English, with current rates, the post-Wayfair economic-nexus rules, and authoritative sources.
The headline rate
California's statewide base sales tax rate is 7.25%. That breaks down as:
- 6.00% state portion (state general fund + local revenue fund)
- 1.25% mandatory uniform local rate (county and city)
Most California cities and counties layer an additional district tax on top — typical district taxes are 0.25% to 2.50%, and the combined rate at any given address ranges from 7.25% (in the few areas with no district tax) to 10.75% in San Francisco transit districts and parts of LA County. To find the exact combined rate for an invoice destination, use the CDTFA's Find a Sales and Use Tax Rate ZIP-code lookup tool.
Do you need to register?
If your business is physically located in California:yes. Any business making taxable sales from a California location must register with CDTFA for a Seller's Permit and collect sales tax on California sales of tangible personal property. The permit is free; processing typically takes 1-3 business days.
If your business is outside California: the post-Wayfair economic nexus rules apply. You must register and collect California sales tax once you make $500,000 or more in California salesin the current or prior calendar year. There's no transaction-count threshold — California eliminated the 200-transaction prong in 2019. Until you cross the $500,000 threshold, no California sales-tax obligation exists for the out-of-state seller.
If you sell only through marketplaces:registered marketplace facilitators (Amazon, Etsy, eBay, Walmart Marketplace) collect California sales tax on third-party sellers' behalf since October 2019. A seller operating exclusively through these marketplaces typically doesn't need to register independently — the facilitator handles it. A seller with both marketplace and direct-sales channels has to count combined California sales toward the $500K threshold and register for the direct-sales portion if applicable.
What's taxable, what isn't
California taxes tangible personal property (physical goods) and a narrow list of specific services. Most professional services — consulting, design, accounting, legal, photography services, freelance work — are not taxed. Mixed transactions where you deliver both services and tangible goods require splitting the invoice: services on a non-taxable line, tangible deliverables on a taxable line.
SaaS, cloud computing, and prewritten downloaded software have historically NOT been taxable in California. This is a common point of confusion because many other states (Texas, New York, Pennsylvania, and others) DO tax SaaS. CDTFA Publication 109 (Non-Taxable Sales) covers the current treatment in detail.
Common exemptions you may apply to California invoices:
- Sales for resale.B2B sales to California-registered resellers with a valid California Resale Certificate (form BOE-230) are exempt from sales tax. Reference the buyer's California Seller's Permit number on the invoice and note "Sale for resale; resale certificate on file."
- Sales to nonprofits generally aretaxed in California, with limited exceptions (sales to certain qualified veterans' organizations, sales for fundraising by qualifying nonprofit youth or church groups, and a few others). Most nonprofits pay full sales tax.
- Sales to government entities are taxed in California unless the sale is to the federal government directly (which is constitutionally exempt). Sales to California state and local government entities are taxable.
- Food sales. Most groceries (cold prepared food, raw food, food for home consumption) are exempt; restaurant prepared food and hot beverages are taxable.
What the invoice should show
For a California taxable sale, the invoice should clearly itemize:
- The taxable items with line-item prices
- Subtotal of taxable goods
- Tax label ("Sales tax" or "CA Sales Tax") with the combined rate (e.g., 8.625%)
- Calculated tax amount
- Grand total
Mixed invoices (taxable + non-taxable items) should subtotal each separately so the tax calculation is unambiguous. Issueable's invoice generator supports per-line tax handling for exactly this case.
Use tax — what California buyers owe
Sales tax is paid by the buyer to the seller at the point of sale; use taxis owed by the buyer when they purchase taxable goods from an unregistered seller (typically out-of-state internet purchases where the seller doesn't collect California tax). Use tax is owed at the same combined rate as sales tax. California businesses report use tax on their CDTFA returns; California consumers report use tax on their state income tax return (Form 540, line 91) or directly to CDTFA.
The economic-nexus rules largely shifted use-tax collection to seller-side sales-tax collection — out-of-state sellers above $500K now collect tax at the point of sale instead of leaving it to the buyer to self-report.
Frequently asked questions
What is California's state sales tax rate?
California's statewide base sales tax rate is 7.25% — the highest base rate of any US state with a sales tax. This 7.25% comprises a 6.00% state portion and a 1.25% mandatory local portion that funds county and city services. Most California sales also incur an additional discretionary district tax that varies by city — typical combined rates are 8.0%-9.5%, with some Bay Area and LA-area districts reaching 10.25%-10.75%. The CDTFA (California Department of Tax and Fee Administration) publishes the current combined rate by ZIP code at cdtfa.ca.gov.
Do I need to charge California sales tax if I'm not based in California?
Yes, if you exceed the economic nexus threshold. Out-of-state sellers must register and collect California sales tax once they make $500,000 or more in California sales in the current or prior calendar year. There is no transaction-count threshold (California eliminated the 200-transaction prong in 2019). The threshold applies to combined sales of tangible personal property delivered to California — services-only revenue typically doesn't count toward the threshold. Marketplace sales facilitated by registered marketplace facilitators (Amazon, Etsy, eBay) also count toward the threshold even though the facilitator collects on the seller's behalf.
Does California tax services?
Generally no. California is one of the majority of US states that doesn't tax most professional and personal services — consulting, design, accounting, legal, financial planning, photography services, freelance work, etc. are typically not subject to sales tax. Tangible personal property IS taxed. Mixed transactions (e.g., a graphic designer who delivers both design services and printed materials) require splitting the invoice — services on a non-taxable line, tangible deliverables on a taxable line. SaaS / cloud computing has historically NOT been taxed in California, though this has been periodically debated; check CDTFA Publication 109 for current treatment.
What about marketplace facilitator rules?
Since October 2019, marketplace facilitators (Amazon, Etsy, eBay, Walmart Marketplace, etc.) that meet California's economic nexus threshold must collect and remit California sales tax on behalf of third-party sellers using their platforms. Sellers operating exclusively through registered marketplace facilitators don't need to register or collect California sales tax themselves — the facilitator handles it. However, a seller with both marketplace and direct-sale channels still has to register for the direct-sale portion if those direct sales push them over the $500K threshold (counting all California sales, marketplace + direct).
How do I claim a resale exemption on a California invoice?
B2B sales to California-registered resellers can be exempt from sales tax if the buyer provides a valid California Resale Certificate (form BOE-230, Section 6092 of the California Sales and Use Tax Law). The seller retains the certificate (typically a one-time submission, not per-transaction) and applies zero tax on qualifying transactions. The invoice should reference the buyer's California Seller's Permit number and note 'Sale for resale; resale certificate on file.' Misuse of resale exemptions — the buyer ultimately consuming the goods rather than reselling — is a focus area for CDTFA audit examinations and a felony if intentional.
What's the difference between sales tax and use tax in California?
Sales tax is paid by the buyer to the seller at the point of sale; use tax is owed by the buyer when they purchase taxable goods from an unregistered seller (typically out-of-state internet purchases where the seller doesn't collect California tax). Use tax is owed at the same combined rate as sales tax. California businesses report use tax on their CDTFA returns; California consumers report use tax on their state income tax returns or directly to CDTFA. The economic-nexus rules largely shifted use-tax collection to seller-side sales tax collection — out-of-state sellers above $500K now collect tax instead of leaving it to the buyer.
Are there special California rules for SaaS, digital products, or downloaded software?
California has historically NOT taxed prewritten downloaded software or SaaS subscriptions — these are treated as non-taxable services rather than tangible personal property. Custom software developed for a single customer is also generally not taxable. Tangible delivery of software (physical media — DVDs, USB drives) IS taxable on the tangible goods portion. This treatment differs from many other states (Texas, New York, Pennsylvania, and several others tax SaaS); confirm with CDTFA Publication 109 (Non-Taxable Sales) for current rules before assuming non-taxability.
Where can I verify California sales tax rates and rules?
California Department of Tax and Fee Administration (CDTFA) at cdtfa.ca.gov — the state's official tax authority. Look for: 'Find a Sales and Use Tax Rate' tool for ZIP-code-specific combined rates, Publication 73 (Your California Seller's Permit), Publication 109 (Non-Taxable Sales of Services and Other Items), and Regulation 1685 (Marketplace Facilitator Act). For specific transaction questions, CDTFA offers a free taxpayer information line and a written-ruling service.
