What to watch in California
- The highest statewide base rate in the country — and the 7.25% already includes mandatory local components.
- SaaS and electronically delivered software are generally not taxable; tangible software media is.
- District (local) tax collection obligations attach separately — a retailer can owe some district taxes and not others.
Rates, thresholds, and taxability change mid-year — verify against the California Department of Tax and Fee Administration (CDTFA) before advising. In L3i, every determination is cited to the controlling authority.
The California voluntary disclosure agreement.
Behind in California? There’s a front door. The voluntary disclosure program lets a business settle unregistered-period exposure on defined terms — before the state finds it first. The terms that shape the client conversation:
Administered by the California Department of Tax and Fee Administration ↗. Program terms as of February 2026 — confirm current terms before filing. L3i pairs the exposure math with the filing itself — see exposure analysis & VDA services.
California, in brief.
What is the economic nexus threshold in California?
$500,000 in sales, effective April 1, 2019. Preceding or current calendar year; includes all sales of tangible personal property, including marketplace sales. Once the threshold is crossed, remote sellers must register with the California Department of Tax and Fee Administration (CDTFA) and begin collecting.
What is the sales tax rate in California?
The state sales tax rate is 7.25%. District taxes push combined rates as high as ~10.75% in some cities.
Do marketplace facilitators collect California sales tax?
Yes — marketplace facilitators have been required to collect since October 1, 2019. Direct (non-marketplace) sales remain the seller’s obligation.
How does a remote seller register for California sales tax?
Register with the California Department of Tax and Fee Administration (CDTFA) before collecting — a remote seller must register once it crosses the economic nexus threshold ($500,000 in sales).
Does California offer a voluntary disclosure agreement (VDA)?
Yes — the California Department of Tax and Fee Administration administers a voluntary disclosure program with a lookback of 36 months (3 years). Penalties are generally waived; interest is generally still due. An advisor can approach the state anonymously before disclosing the client’s identity.
