new client to me - shuts down CA S corp 2015 and files last return in 2016, well files a final return without filing the dissolution certificate for CA. They send a bill for $1600 for 2016 and 2017 franchise tax.

He writes a letter and files form DSF STK in 2018 - hears nothing back and no further collection efforts. 

He gets a letter and a fine for a Corporation Past Due notice for $250. 

Any CA folks have any friendly advice here? I checked on the SoS and the S-corp is still active - I'm hoping not to go through the application for certificate of revivor....
