In California, how often do you get billed for your business license? -

I know you get billed by the County Assessors office (at least in L.A. county). I noticed my license is expired, but I have not received a bill. How can I check this? I don t want to get fined or have my business closed.

I m in LA County and my business license is through the city not the county. I get billed once a year.
