Four distinctions for labor taxability.

If California is taxing labor services you provide or receive — or CDTFA sent a notice about labor taxability:

California’s rules on whether labor is taxable are highly fact-specific and frequently disputed in audits. A free 15-minute call covers whether your specific transactions should be taxable under California law, what CDTFA is likely to focus on, and what a protest or appeal looks like for your situation.

In California, labor by itself is not subject to sales tax — but fabrication labor is. If your work creates or assembles a product (cutting, bending, machining, assembling parts into something new), the CDTFA treats that labor as part of a taxable sale. Repair and installation labor is generally not taxable when it’s separately stated on the invoice. The line between “fabrication” and “repair” is exactly where CDTFA audits attack, because reclassifying your labor turns years of untaxed invoices into a tax bill.

Quick Reference

Jump to: fabrication, installation, repair, or services.

1. Fabrication Labor

Labor to create, produce, assemble TPP is taxable.

If this is you: Creating / producing / fabricating tangible personal property. Labor to produce product is part of sales price. Taxable. Custom manufacturing typical example.

Fabrication Strategy

  1. Identify fabrication activities.
  2. Include labor in taxable sales price.
  3. Distinguish from installation / repair.
  4. Document character.
  5. Report on CDTFA return.

2. Installation Labor

Installation of TPP on real property generally exempt.

If this is you: Installing TPP for customer (appliances, equipment). Labor generally exempt when separately stated. Sale of property still taxable.

3. Repair Labor

Repair labor exempt if separately stated from parts.

If this is you: Auto mechanic, appliance repair, equipment repair. Labor separately stated from parts = labor exempt, parts taxable. Bundled pricing = all taxable.

4. Services to Property

Facts-specific analysis of whether service results in TPP.

If this is you: Custom programming, design, consulting. If results in TPP transfer, analysis required. Pure services generally not taxable. Bundled with TPP transfer may be.
