California sales tax isn't optional and the rules are specific to California. Most LA small businesses benefit from understanding the basics even when they have a bookkeeper handling filings. This is a practical guide to what you need to know and when to call your tax pro.

What California sales tax is

California's sales tax is a transaction tax applied to retail sales of tangible goods and certain services. The current base rate in Los Angeles County (as of 2026) is approximately 9.5% — this combines the California state rate, the Los Angeles County rate, and any applicable district taxes. Most LA addresses are subject to a uniform countywide rate, but specific addresses in cities with their own district taxes (e.g., parts of Avalon, parts of Santa Monica pre-2022) may have slightly different totals. Confirm your exact rate with CDTFA or your bookkeeper.

If you sell taxable goods or services in California, you likely owe sales tax — and you need to register, collect, report, and remit.

What counts as taxable in California

This is broader than most people expect. California taxes:

Tangible goods

Most physical products are taxable:
- Retail merchandise sold to California customers
- Online sales shipped to California addresses
- Software delivered electronically is generally NOT taxable in California (post-Wayfair, with some exceptions for software-as-a-service arrangements)
- Food for home consumption (groceries) is NOT taxed in California (rare exception to sales tax)
- Restaurant food IS taxed at the standard rate
- Candy is taxed differently depending on the type

Specific services

California taxes a narrower set of services than many states, but several common ones:

  • Sales of products even when bundled with services (the services component depends on facts)
  • Installation labor for taxable goods (taxed with the goods in many cases)
  • Certain labor in specific industries (manufacturing, fabrication, construction)
  • Telecommunications services broadly taxed
  • Title insurance, certain real estate transfers

Most LA small businesses that aren't in retail may or may not have sales tax obligations depending on what they sell. A bookkeeper or CPA can confirm in 5–10 minutes.

Services that are NOT taxed in California

Most professional services are NOT taxed in California:

  • Consulting services by a professional
  • Lawyer fees
  • Doctor and medical services
  • Accounting services
  • Marketing services (most advertising, marketing strategy)
  • Most repair services to existing items (depends on facts)

If you provide mostly services and you're uncertain, ask. Most queries resolve with "yes, it's a service" or "no, it's a service."

When you need to register

California requires registration if any of these are true:

  • You sell tangible goods to California customers
  • You sell certain services that are taxable under California law
  • You make $10,000 or more in sales to California customers from out-of-state (under economic nexus rules post-Wayfair)
  • You sell on marketplaces like Amazon or Etsy (the marketplace may handle the tax for you in many cases)
  • You have a physical presence in California (including employees, inventory, or an office)

If you're unsure, register and ask the California Department of Tax and Fee Administration (CDTFA) for clarification, or talk to your bookkeeper or CPA. The cost of being wrong on the high side is small; the cost of being wrong on the low side is significant.

How to register

California sales tax registration is done through CDTFA:

1. Apply online at the CDTFA website for a seller's permit
2. Receive your permit typically within a few days
3. Set up your filing frequency — most new businesses are quarterly; high-volume businesses may be monthly
4. Set up your payment methods — most payments are electronic

Your bookkeeper can usually handle this entire process in a few hours.

Filing frequency

California assigns filing frequency based on expected sales volume:

  • Monthly if you expect to owe more than $17,500 in any quarter (most high-volume retail)
  • Quarterly if you expect to owe $1,500–$17,500 per quarter (most small businesses)
  • Annually if you expect to owe less than $1,500 per quarter (smallest businesses)

You're assigned to one based on your registration estimate, but you can request a different frequency.

Filing due dates

For monthly filers:

  • Sales of January are reported and paid by February 28 (or 29)
  • Sales of February are reported and paid by March 31
  • And so on

For quarterly filers:

  • Q1 (Jan–Mar) sales are reported and paid by April 30
  • Q2 (Apr–Jun) sales are reported and paid by July 31
  • Q3 (Jul–Sep) sales are reported and paid by October 31
  • Q4 (Oct–Dec) sales are reported and paid by January 31

Late filings incur penalties. A bookkeeper can keep this on track.

Common mistakes

A few patterns that catch LA small businesses:

Forgetting to register

If you start selling without registering, you're likely to owe back taxes plus penalties when you register. Better to register before you start.

Mixing taxable and non-taxable revenue

Most service businesses don't have sales tax; some retail businesses do entirely. If you have both, separating them in your bookkeeping prevents misfilings.

Misclassifying products as services

If you sell a product with installation, the tax treatment is different from selling a service alone. The product component is usually taxable.

Undercharging clients who pay sales tax

Most sales tax is passed through to customers. If you're charging clients sales tax on top of your service fee, you owe that to the state.

Missing marketplace facilitator rules

Since 2019, marketplaces like Amazon, Etsy, and most delivery platforms handle sales tax on your behalf. If you sell on these platforms, the platform collects and remits. You don't owe the tax, but you do need to report the marketplace sales on your return.

What to track monthly or quarterly

If you collect sales tax, you need:

  • Total taxable sales for the period
  • Total non-taxable sales for the period
  • Sales tax collected (computed at the appropriate rate)
  • Use tax on purchases (tax you owe on items you bought without paying sales tax that you use for your business)
  • District tax adjustments for any specific districts that apply

Most of this is straightforward bookkeeping. The bookkeeper tracks it through categorization and produces the report.

When to call a tax professional

A bookkeeper typically files sales tax if your situation is straightforward. A tax pro is needed when:

  • Multiple product types with different tax treatments
  • Sales across state lines (multi-state nexus)
  • Marketplace facilitator complications
  • Sales tax audits (rare but real)
  • Significant use tax (you bought goods for resale without paying tax)

Most LA small businesses with simple retail or food service sales can be handled by a competent bookkeeper.

LA-specific things

A few LA-specific items to know:

  • City of Los Angeles sales tax is part of the Los Angeles County rate. There isn't a separate city sales tax — the county is the rate setting body.
  • District taxes vary by specific address. Most LA addresses fall under the countywide uniform rate, but some are in special districts.
  • Los Angeles County transient occupancy tax for hotels (separate from sales tax, applied to room rates)
  • California use tax for goods you purchased from out-of-state sellers for use in California

Most of this is detail the bookkeeper handles, but it's worth knowing.

Sales tax and bookkeeping

A few practical things for the bookkeeper relationship:

  • Categorize sales by taxable status so the report is straightforward
  • Track sales tax collected separately from revenue (it's a liability, not income)
  • Track use tax paid separately for any business purchases
  • Keep marketplace and direct sales separate so each can be reported correctly
  • Reconcile sales tax deposits to bank statements each filing period

A few hours of monthly work prevents most of the mistakes that catch small businesses.

Practical setup for a new business

If you're just starting:

1. Apply for a seller's permit through CDTFA
2. Set up sales tax collection at your point of sale (Stripe, Square, Shopify, etc. handle most of this automatically)
3. Communicate that prices include sales tax (most LA businesses list prices without tax and add at sale)
4. File on the cadence assigned to you (monthly or quarterly)
5. Pay what you owe by the due date

Most new businesses get this right by following the steps.

Common scenarios

A few scenarios and what they say:

"I'm a service-only business but I sold a product"

The product is usually taxable. The service is usually not. Separate them.

"I sell software"

Generally not taxable in California. But if it's bundled with implementation services, the picture may change.

"I sell on Amazon"

Amazon handles the sales tax for you (since marketplace facilitator laws). You owe the tax indirectly through Amazon's pricing structure but don't file separately.

"I bought something for the business from a non-California supplier"

May owe use tax. Most small businesses ignore this. It's not huge but it's real.

"The CDTFA audited me"

Most small-business sales tax audits are about specific records you should have kept (invoices, exemption certificates, marketplace reports). A bookkeeper can help you respond.
