California sales tax at a glance

Verified against CDTFA published guidance, current as of June 2026.

Statewide base rate

7.25%

6.00% state + 1.25% uniform local. Districts add on top.

Max combined rate

up to 10.75%

Alameda, Long Beach, Albany, Azusa reach the cap.

Economic nexus

Marketplace law

Since Oct 2019

Marketplace facilitators collect & remit. Sales still count toward your threshold.

Filing frequency (monthly / quarterly / annual) is assigned by CDTFA based on your collected volume. Returns generally due last day of the month following the period; quarterly prepayments due the 24th of the first two months of each quarter.

What’s included

End-to-end California sales tax handled

Every plan includes CDTFA registration, ongoing return prep and filing, district-rate breakdowns, and a dedicated account rep. Add audit defense or special data processing when you need them.

01

CDTFA registration

Seller’s permit application, multi-location handling, and use-tax registration. $125 flat per registration.

02

Monthly & quarterly returns

We prepare, reconcile, and file your California returns — including district-level allocation across all 1,000+ jurisdictions.

03

Marketplace reconciliation

Separate marketplace-facilitator sales from your direct sales so you don’t double-collect or under-report.

04

Notice handling

CDTFA notices come to us first. We respond, document, and keep your account in good standing.

05

Audit defense

Representation during CDTFA audits — $125/hour. We’ve been through hundreds of California audits since 2002.

06

Voluntary disclosure

If you’re behind on California filings, we negotiate VDAs with CDTFA to reduce penalties and back-period exposure.
