California sales tax on services generally doesn’t apply: the state’s sales and use tax is built around retail sales of tangible personal property, not labor or expertise. Consulting, legal work, medical care, accounting, and similar pure services sit outside the tax base. The complications start when labor produces a new physical item, when parts are supplied along with repair work, or when a single invoice bundles services with taxable goods. The statewide base rate is 7.25%, with local district taxes pushing most combined rates higher.1California Department of Tax and Fee Administration. Sales and Use Tax in California
The General Rule for Services
The California Department of Tax and Fee Administration (CDTFA) collects sales and use tax on transfers of goods and merchandise. Because the tax is tied to physical property changing hands, labor-only transactions don’t trigger it. A lawyer billing for advice, an accountant preparing a return, a janitor cleaning an office, or a consultant delivering recommendations owes no sales tax on those fees.
Labor does become taxable, however, when it is involved in creating or manufacturing new tangible personal property.2California Department of Tax and Fee Administration. What Is Taxable That one distinction — whether the labor produces a new item or operates on an existing one — explains most of the rules below.
Fabrication: Labor That Creates New Property
Fabrication is the big exception. When someone uses labor to produce, process, or assemble a new physical item for a customer, the entire charge is taxable, labor included. Revenue and Taxation Code Section 6006(b) defines producing or fabricating tangible personal property for a consumer as a “sale,” even if the customer supplies the raw materials.3California Legislative Information. California Revenue and Taxation Code 6006
It doesn’t matter whether the labor is itemized separately or buried in the product price. A print shop producing custom brochures, a machinist making a one-off part, or a jeweler sizing and engraving a new ring owes tax on the full amount.4California Department of Tax and Fee Administration. Publication 108 – Taxable Labor
Altering a new item counts as fabrication too. Tailoring a new suit to fit the buyer, or restyling a new garment before it leaves the store, is treated as creating a new item, and the alteration charge is taxable.4California Department of Tax and Fee Administration. Publication 108 – Taxable Labor A narrow carve-out exists for businesses whose main trade is cleaning or dyeing clothing.5California Department of Tax and Fee Administration.

Repair and Installation Labor
Work on an existing item is treated very differently from fabrication. Fixing a broken appliance, restoring furniture, replacing a car’s alternator — the labor itself is not taxable. Parts and materials used in the repair are.6California Department of Tax and Fee Administration. Labor Charges – Nontaxable Charges
The condition attached to that nontaxable status is strict: the invoice must separately state labor charges and parts charges. Revenue and Taxation Code Section 6012 excludes repair and installation labor from the tax base only when the charges are broken out.7California Department of Tax and Fee Administration. California Revenue and Taxation Code 6012 – Gross Receipts A single lump-sum bill can make the whole amount taxable.
The 10% Parts Rule
Small-parts repairs get a simpler treatment. When the retail value of the parts used is 10% or less of the total charge and no separate charge is made for them, the repair person is treated as the consumer of those parts. They pay tax on the parts when they buy them, and the customer sees no tax on the bill. Once parts exceed 10% of the total, the repair person must itemize and collect tax on the retail selling price of the parts.6California Department of Tax and Fee Administration. Labor Charges – Nontaxable Charges
Installing Something the Customer Just Bought
Labor for installing a newly purchased product — mounting a TV, setting up equipment — is excluded from the tax base when the installation charge is separately stated on the invoice.7California Department of Tax and Fee Administration. California Revenue and Taxation Code 6012 – Gross Receipts The product remains taxable. The installation labor doesn’t add to the taxable amount, provided the invoice shows it on its own line.
Mixed Transactions and the True Object Test
Many real-world jobs blend service and goods. A graphic designer delivers consulting plus printed proofs. An engineer provides analysis and hands over a bound report. California applies the “true object” test to decide which side controls the tax treatment.
The test asks what the buyer was actually paying for. If the real object was the service, the transaction is nontaxable even though some physical property changed hands. If the buyer’s goal was the physical product, the labor behind it doesn’t save the deal from tax.8California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 515.0040
A technology consultant who delivers a strategic report can keep the transaction nontaxable by making clear the client is paying for analysis; a printed binder is incidental. A photographer who delivers prints or albums is selling tangible personal property no matter how much artistic labor went into the shoot. Separate invoicing for service charges and any tangible-property charges strengthens the position when the line is close.
Software, SaaS, and Digital Products
For software, how it reaches the customer matters more than what it does.
Pre-written software delivered on a flash drive or disc is taxable tangible personal property. The same software downloaded electronically is generally not taxable. One trap: if a seller delivers software electronically and also provides a physical backup copy, the entire transaction becomes taxable.9California Department of Tax and Fee Administration. Internet Sales (Publication 109) Nontaxable Sales
Custom software developed for a specific client is a nontaxable service under Revenue and Taxation Code Section 6010.9, even when delivered alongside hardware. If the custom work is really a modification of pre-written code, the modification charges have to be separately stated to qualify.10California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 120.0000
Software as a Service is not taxable in California. The CDTFA has consistently treated charges for remote database access or hosted software as something other than the sale or lease of tangible personal property.10California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 120.0000 Enterprise cloud platforms, subscription productivity tools, hosted analytics — none of them trigger sales tax as long as no physical copy of the software reaches the customer.
Construction Work
Construction surprises people because contractors generally aren’t retailers of what they install. A contractor who furnishes and installs materials is treated as the consumer of those materials. The contractor pays sales or use tax when buying lumber, drywall, pipe, or wire, and that cost is folded into the contract price. No separate tax line appears on the property owner’s bill for those materials.11California Department of Tax and Fee Administration. Construction and Building Contractors
Fixtures are the exception. Contractors are retailers of the fixtures they furnish and install, so tax applies to the sale of those fixtures to the property owner. The same retailer treatment covers machinery and equipment furnished under a construction contract.12Legal Information Institute. California Code of Regulations Title 18, Section 1521 – Construction Contractors A remodeling invoice may show sales tax on cabinets and appliances but none on the framing lumber or drywall, because that tax was already paid upstream.
Optional Warranties
Extended warranties and optional service contracts have their own treatment. When a dealer sells an optional warranty and later makes repairs under it, the dealer is treated as the consumer of the repair parts. Tax is owed on the parts at the dealer’s cost when they are purchased, and the customer sees no additional tax when a repair is performed.13California Department of Tax and Fee Administration. Warranties and Maintenance Agreements (Publication 119) Optional Warranties From the customer’s side, warranty-covered repairs look tax-free; the tax is built into the warranty price.
Why Invoicing Decides So Much
A single pattern runs through nearly every rule above. Repair labor is nontaxable only if separately stated from parts. Installation labor is excluded only when broken out from the product price. Custom software modifications must be itemized to avoid being taxed as pre-written code. The true object test is easier to win when service charges stand apart from any physical items delivered.
Lump-sum billing is the most common way otherwise nontaxable service charges become taxable in California. If you provide services, itemize. If you’re paying for services, check that the invoice separates labor, parts, and product charges before you settle it.7California Department of Tax and Fee Administration.
