California Resale Certificate (CDTFA-230): A Reseller's Guide to Sales Tax Exemption in Los Angeles
I'm a CPA who specializes in one corner of tax most of my peers avoid: California sales and use tax. A big part of my practice is resellers — retailers, wholesalers, distributors, and online sellers across the Los Angeles area who are either overpaying tax they never owed or setting themselves up for an audit without realizing it.
The good news for resellers is that your path to sales tax exemption is cleaner than a contractor's. Done right, a California resale certificate lets you buy inventory tax-free and increase your bottom line legally — no gimmicks, fully defensible. Here's exactly how it works in LA, and where I see sellers slip up.
Quick note: this is education, not advice for your specific business. When it matters, call a professional — my number is at the bottom.
What You're Paying in Los Angeles
California's statewide base rate is 7.25% — the floor, everywhere. In Los Angeles, district taxes push it higher: combined rates across LA County commonly land around 9.5% and climb past 10% in many cities. Confirm the exact rate for your business address, because it varies city to city.
Don't forget use tax. Buy inventory or supplies from an out-of-state or online seller who doesn't charge California tax, and you owe use tax when you bring the goods here. Buying out of state rarely saves what people think it does.
Resale Certificate vs. Exemption Certificate: Not the Same Thing
This is the confusion I clear up most often, so let's settle it:
A resale certificate defers tax. You buy goods tax-free and collect sales tax when you sell to the end customer. The tax still gets paid — once, at the retail level. This is the reseller's everyday tool.
An exemption certificate removes tax on a genuinely exempt transaction or buyer — for example, the partial exemption on manufacturing equipment.
Read that first point twice. A resale certificate doesn't make tax disappear — it moves it down the chain to the final sale, where you collect and remit it.
The Seller's Permit Comes First
Here's a detail that surprises out-of-state sellers: in many states the resale certificate is the primary document. In California, it isn't. The seller's permit is the foundation, and your resale certificate is only valid because you hold one.
The permit is issued by the CDTFA and it's free to register.
You cannot issue a valid California resale certificate without one.
If your permit is revoked, suspended, or lapses, every resale certificate you've issued dies with it.
One tip when you register: be conservative with your projected monthly sales. Wildly optimistic numbers can trigger a security-deposit request you didn't need to invite.
How to Use the California Resale Certificate (CDTFA-230)
If you're searching "how to get a California resale certificate," here's the actual workflow:
Register for a seller's permit with the CDTFA (free, online).
Get Form CDTFA-230, the General Resale Certificate.
Fill it out completely — your business name, your seller's permit number, and a specific description of what you resell.
Give it to your supplier at or before the time of purchase — never after the sale is done.
The supplier keeps it on file as their proof for not charging you tax.
A few things that quietly matter:
Be specific in the description. "Various goods" is one of the fastest ways to have a certificate thrown out in an audit. Describe what you actually resell.
Big retailers may run their own system. Suppliers like large national chains often won't accept your PDF — you enter your permit number into their tax-exemption portal and their system generates the certificate. Know which suppliers want the form and which want the portal.
Only use it for genuine resale. Buying personal or business-consumption items with a resale certificate is a violation of California tax law, and the CDTFA runs data-matching to catch exactly that.
Blanket vs. Single-Transaction Certificates
You have two ways to issue a resale certificate:
Single-transaction certificate — covers one specific order. Precise, but paperwork-heavy for repeat suppliers.
Blanket certificate — covers all qualifying purchases from one seller until you rescind it. Far more efficient for ongoing relationships.
Most established sellers use blanket certificates with regular suppliers and single-transaction certificates for one-off buys. If some purchases from that supplier don't qualify for resale, flag those separately so the supplier charges tax on them.
The Packaging Win Most Resellers Miss
Packaging that goes to the customer with the product is generally purchased for resale and is tax-free — boxes, mailers, bubble wrap, packing peanuts, and the like. But internal-use items are taxable: tape dispensers, box cutters, and labels you use in the warehouse but don't pass to the customer. Sort your shipping-supply purchases accordingly and stop paying tax on the resale-eligible ones.
The Nonprofit Myth
If you run or supply a nonprofit, know this: being a nonprofit does not automatically exempt purchases from California sales tax. Unlike some states, California doesn't grant a blanket pass based on nonprofit status. A specific statutory exemption has to apply to the particular transaction. "We're a nonprofit" is not a magic phrase at the register.
If You Fabricate or Manufacture: The Partial Exemption
Some resellers also produce or assemble goods. If that's you, look at California's manufacturing and R&D partial exemption on qualifying equipment:
It reduces the state rate by 3.9375% — qualifying equipment is taxed at 3.3125% instead of 7.25%, plus applicable district taxes.
Claimed with certificate CDTFA-230-M. No pre-approval required.
Covers up to $200 million in qualifying purchases per year, currently through June 30, 2030.
Don't Forget Use Tax
The mirror image of sales tax catches resellers all the time. Anything you buy for your own business use — not for resale — from a seller who didn't charge California tax generally carries use tax. Fixtures, office equipment, supplies you consume: track them, because the CDTFA does.
Audit Triggers to Avoid
Vague certificate descriptions ("various goods").
Late certificates provided after the sale.
Using a resale certificate for personal or consumption purchases.
Unreported use tax on out-of-state and online buys.
A lapsed seller's permit invalidating your certificates.
Keep every certificate you issue and accept, organized by supplier and customer, and reconcile exempt purchases against them. An exempt purchase with no matching certificate is an audit adjustment waiting to happen.
Frequently Asked Questions
Do I have to pay for a California resale certificate?
No. The seller's permit that underpins it is free from the CDTFA. Be wary of third-party sites charging you for something the state provides at no cost.
Does a resale certificate mean I never pay sales tax?
No. It defers the tax to the final retail sale. You collect and remit it when you sell to the end customer.
I'm a nonprofit — am I automatically exempt?
No. California doesn't grant blanket exemptions based on nonprofit status. A specific statutory exemption must apply.
What happens if I use a resale certificate for personal purchases?
That's a violation of California tax law, and CDTFA data-matching is built to catch it. Penalties and back tax can follow.
Buy Smarter. Keep More.
For LA resellers, a correctly run resale certificate is one of the simplest ways to protect margin and increase your bottom line legally. But the details — specific descriptions, timing, blanket vs. single, use tax, packaging — are exactly where sellers lose money or invite audits.
