Because in California, missing a sales tax rate change costs more than staying ahead of it.

Sales tax rates shift constantly across California — by city, county, and even special district. But here’s the catch:

If you charge the wrong rate, you still owe state the difference plus penalties and interest. This can easily be 1,000’s
of dollars a month.

And if the CDTFA audits you?

A single missed update can trigger thousands in back tax, fines, and scrutiny.

Get the alerts. Stay compliant.
Avoid costly penalties.
