Update 2/5/21: The reduced annual fee will continue until March 30, 2021.
(Update: readers confirm that the annual fees on cards renewals slated for February 1st will also be the lower $450. We don’t know about March and beyond.)
In April 2020 Chase announced that Chase Sapphire Reserve cardholders with a renewal date between April 1 – July 1 would have a reduced annual fee of $450. That was then extended until the end of December. themaskedmoron now reports receiving an annual fee of $450 in 2021, so it seems that the $550 annual fee has been delayed further. New or upgraded accounts still see the $550 annual fee unfortunately.
