Most services in California aren’t subject to sales tax. California sales tax on services applies only in specific situations, because the state’s sales and use tax is built around the retail sale of tangible personal property—physical items you can see, touch, or weigh—not the labor or expertise behind a service. The statewide base rate is 7.25%, with local district taxes pushing the combined rate higher in most areas. Consulting, legal advice, medical care, accounting, and similar labor-only work fall outside the tax entirely. The exceptions kick in when labor produces, alters, installs, or repairs physical property, and the line between taxable and nontaxable often comes down to how the invoice is written.
The General Rule for Pure Services
California’s sales and use tax applies to sales of goods and merchandise, collected by the California Department of Tax and Fee Administration.1California Department of Tax and Fee Administration. Sales and Use Tax in California Because the tax targets transfers of physical property, transactions that are purely labor or advice sit outside its reach. Some labor services do become taxable when the work is involved in creating or manufacturing new tangible personal property.2California Department of Tax and Fee Administration. What Is Taxable That distinction—whether the labor produces a new physical item—runs through every exception below.
Fabrication Labor: Making New Items
The biggest exception is fabrication. When labor is used to create, produce, process, or assemble a new physical item for a customer, the full charge—labor included—is subject to sales tax. Under Revenue and Taxation Code Section 6006(b), producing or fabricating tangible personal property for a consumer counts as a “sale,” even when the customer supplies the raw materials.3California Legislative Information. California Revenue and Taxation Code 6006
This is true whether labor charges are itemized on the invoice or rolled into the product price. A print shop producing custom brochures, a machinist making a bespoke part, or a jeweler sizing and engraving a new ring all owe tax on the entire amount charged.4California Department of Tax and Fee Administration. Publication 108 – Taxable Labor
Altering new items also falls under fabrication. Tailoring a new suit to fit the buyer, or restyling a new garment, counts as creating a new item for that customer, and the alteration charges are taxable.4California Department of Tax and Fee Administration. Publication 108 – Taxable Labor A narrow carve-out exists for businesses primarily engaged in cleaning or dyeing clothing, but a standalone tailor or a clothing retailer offering in-house alterations won’t qualify.5California Department of Tax and Fee Administration.

Repair and Installation Labor
Work performed on an item that already exists is treated very differently. Fixing a broken appliance, restoring furniture, or replacing an alternator involves repair labor that is not taxable, though the parts and materials used in the repair are.6California Department of Tax and Fee Administration. Labor Charges – Nontaxable Charges The catch: the invoice has to separately state labor and parts. Revenue and Taxation Code Section 6012 excludes installation and repair 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 lump sum that combines everything into one number risks making the whole amount taxable.
The 10% Parts Rule
California has a useful threshold for small-parts repairs. If the retail value of parts and materials used in a job 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. Tax is paid when the repair person buys the parts, and the customer’s bill shows no tax at all. Once parts exceed 10% of the total charge, the repair person must itemize and collect tax on the fair retail selling price of those parts.6California Department of Tax and Fee Administration. Labor Charges – Nontaxable Charges
Installing a Newly Purchased Item
Labor for installing a product the customer just bought—mounting a new TV, setting up purchased equipment—is excluded from the tax base when the installation charge is separately stated.7California Department of Tax and Fee Administration. California Revenue and Taxation Code 6012 – Gross Receipts The product remains taxable, but the installation labor doesn’t add to the taxable amount. Bundling it all together invites the CDTFA to tax the whole charge.
Construction Contractors
Construction is one of the most commonly misunderstood corners of California sales tax. A construction contractor is generally treated as the consumer of the materials they furnish and install, not as a retailer selling those materials to the property owner. The contractor pays sales or use tax when buying the materials, and that cost is built into the contract price without showing up as a separate tax line on the owner’s bill.8California Department of Tax and Fee Administration. Construction and Building Contractors
Fixtures are handled differently. Contractors are retailers of fixtures they furnish and install, meaning tax applies to their sale of the fixtures to the property owner.9Legal Information Institute. California Code of Regulations Title 18, Section 1521 – Construction Contractors The same retailer treatment applies to machinery and equipment furnished under a construction contract. A remodeling invoice might therefore include sales tax on fixtures and equipment but not on lumber or drywall, because those material taxes were already paid at the supply house.
Under a lump-sum contract, the contractor is always the consumer of materials. Under a time-and-materials contract, the contractor is generally still the consumer.8California Department of Tax and Fee Administration. Construction and Building Contractors If a contract explicitly transfers title to the materials before installation and separately states the sale price of those materials apart from installation, the contractor can be treated as the retailer instead.9Legal Information Institute. California Code of Regulations Title 18, Section 1521 – Construction Contractors
Software and Digital Products
How software is delivered matters more than what the software does.
Pre-Written Software
Pre-written (sometimes called “canned”) software delivered on a physical medium—a flash drive, a disc—is taxable tangible personal property. The same software downloaded electronically is generally not taxable, because no physical item changes hands. One trap: if a seller delivers software electronically but also provides a physical backup copy on a flash drive, the entire transaction becomes taxable.10California Department of Tax and Fee Administration. Internet Sales (Publication 109) Nontaxable Sales
Custom Software
Software developed specifically for a client’s needs is treated as a nontaxable service under Revenue and Taxation Code Section 6010.9, even when delivered alongside hardware. If a seller bundles custom software with computer equipment without breaking out the price, a reasonable allowance for the software’s value is excluded from the taxable amount.11California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 120.0000 If the software is a substantially modified version of pre-written code, the modification charges must be separately stated on the invoice to qualify.
SaaS and Cloud Access
Software as a Service, where the customer accesses software remotely through a browser or app without receiving a copy, is not taxable. The CDTFA has consistently held that charges for accessing a remote database or using hosted software don’t amount to a sale or lease of tangible personal property.11California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 120.0000 That covers enterprise cloud platforms and subscription-based productivity tools alike, as long as no physical copy is delivered.
Mixed Transactions and the True Object Test
Many real deals involve both a service and some transfer of physical property. A graphic designer delivers consulting plus printed proofs. An engineer provides analysis and hands over a bound report. When a transaction blends taxable goods with nontaxable services, California applies the “true object” test to decide which element controls.
The test asks what the buyer actually wanted. If the real object of the transaction is the service, the deal is nontaxable even though some tangible property changes hands. If the buyer’s real goal was the physical product, the labor to create it doesn’t save the transaction from tax.12California Department of Tax and Fee Administration. Sales and Use Tax Annotations – 515.0040
Clear invoicing helps. A technology consultant who delivers a strategic report can keep the transaction nontaxable by making clear the client is paying for the analysis, with the printed binder incidental. A photographer who delivers prints or albums is selling tangible personal property no matter how much artistic labor went into the shoot.
Optional Warranties and Maintenance Contracts
Extended warranties and optional service contracts have their own treatment. When a dealer sells an optional warranty and later performs repairs under it, the dealer is treated as the consumer of the repair parts. The dealer owes tax on the cost of those parts at the time of purchase, and the customer pays no additional tax when the repair happens. If the warranty requires the customer to pay a deductible, the calculation shifts and part of the receipts become subject to sales tax.13California Department of Tax and Fee Administration. Warranties and Maintenance Agreements (Publication 119) Optional Warranties For most customers, tax on warranty repairs is invisible, baked into the original warranty price rather than added to each service visit.
Why Invoicing Drives the Outcome
A pattern runs through nearly every category above: how you structure the invoice can determine whether a charge is taxable. 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 software. Lump-sum billing is the most common way that otherwise nontaxable service charges become taxable in California.7California Department of Tax and Fee Administration. California Revenue and Taxation Code 6012 – Gross Receipts
For service providers, the lesson is to itemize. For buyers, it’s worth checking that invoices clearly separate labor, parts, and product charges before paying. A few extra line items can be the difference between a nontaxable service and a fully taxable sale.
