New CA law starting Jan 1 2025:
All state-chartered (not federal) credit unions and banks in Calif can no longer charge overdraft fees where it's declined immediately due to insufficient funds. Assembly Bill 2017 applies to banks and credit unions that are regulated by the state of Calif. From CalMatters website: "The law covers instances in which banks charge customers when their withdrawals are declined instantaneously, such as at ATMs, because of insufficient funds. It takes effect Jan. 1."

According to CalMatters, the CA Credit Union League first opposed the bill but eventually took a neutral position. Didn't say how the banks felt, they probably hate losing a juicy source of profits. This bill only covers delcines that happen instantly. But.......
Yet another new Calif law, but this one won't take effect until Jan 1 2026, is: State Senate Bill 1075, which will limit CA-chartered credit-union fees for insufficient funds to $14 unless a lower federal limit is set.
