I retired in December 2020 and got some severance pay in January 2021; this bumped up my earnings for 2021. I started Medicare last year, midyear 2022, a year and a half after the severance payment. Because of the severance, I'm paying ungodly IRMAA Medicare fees that I expect will go back down come January 2024. Now that I've filed our 2022 taxes (no severance there, just retirement), I'm wondering if I can make a case for getting the IRMAA fees cut immediately. Thanks in advance, AKB.
