California generally doesn’t require you to charge sales tax on cleaning services. Labor and services aren’t subject to sales tax in the state. When you clean a home or office, the work itself is exempt, so your invoice for the service doesn’t need a sales tax line.

The exception shows up when you sell tangible goods to a customer. If you resell a bottle of cleaner or list supplies as a separate charge on an invoice, those product sales are taxable. The distinction comes down to whether you’re providing a service or transferring ownership of a physical product.

Supplies you use up during the job don’t count as product sales. The paper towels, spray bottles, and cleaning solutions consumed while you work are part of your cost of doing the service. You paid sales tax when you bought them at the supply store and that’s the end of it. You aren’t required to charge customers sales tax on what you used to complete their job.

Separately itemized products are different. If an invoice shows a line for cleaning service and another line for supplies left with the client, that product line is a taxable sale. The same applies if a client asks to buy a pack of microfiber cloths from you. In that transaction you’re acting as a retailer, not a service provider.

Most operators in the cleaning services industry never sell products, so they don’t need a seller’s permit or sales tax account. If your business is pure service work, California sales tax doesn’t apply to what you charge.

If you do sell products, register with the California Department of Tax and Fee Administration for a seller’s permit. You collect sales tax on those product sales, file returns on the schedule they assign based on volume, and remit what you collected. Filing frequency can be monthly, quarterly, or annually depending on how much you sell.

Keep your books structured so service revenue and product sales are tracked separately. If the CDTFA ever reviews your records, you need to show clearly what was non-taxable service work and what was taxable product revenue. Mixing the two together creates a mess that’s much harder to unwind after the fact than it is to track properly from the start.

One more thing to watch. Combined billing for a service like post-construction cleanup where materials are used up during the work stays treated as service revenue. What triggers sales tax is physical product ending up in the customer’s possession after the job is done, not supplies consumed to complete it.
