The IRS and FTB websites say its an automatic extension until Oct 16th. 

I sent all my entity extensions in back before I saw the announcement for the extended due date, Im not going to fuss with 4868s.

I AM encouraging people to not wait until Oct to pay everything (they extended the 4th qtr 2022 estimate as well as the first 3 2023 estimates until Oct 16th too!), people just get too far behind.
